[0027] A hydraulic module is an integrated circulating water delivery device commonly used in air conditioners, which enables hot water preparation by using a refrigerant from an air conditioning system by connecting a water heating pipeline to the air conditioning system.

[0028] The hydraulic module typically includes a housing, a display panel, and an electric control box. The display panel is mounted on an outer surface of the housing and is electrically connected to the electric control box arranged inside the housing. However, if an internal structure of the hydraulic module is not properly configured, assembly between the display panel and the housing may be complicated, thereby reducing assembly efficiency of the hydraulic module. This makes wiring of the display panel and the electric control box inconvenient, and also makes maintenance and repair of components inside the hydraulic module inconvenient.

[0029] Accordingly, some embodiments of the present disclosure provide a hydraulic module 1. The hydraulic module 1 can be applied to air conditioners, or may be applied to floor heating, radiators, or other domestic heating devices, and is configured to heat or cool water flowing therethrough to output water at a set temperature.

[0030] In some embodiments, as shown in FIG. 1, the hydraulic module 1 includes a housing 100. One side of the housing 100 is open to form an opening. For example, the housing 100 is substantially a lidless cuboid.

[0031] In some embodiments, as shown in FIG. 1, the hydraulic module 1 further includes a first panel 300. The first panel 300 is fixedly connected to the housing 100, and seals the opening. The housing 100 and the first panel 300 together define an accommodating cavity 110. For example, the first panel 300 is in a shape of a rectangle.

[0032] In some embodiments, as shown in FIG. 1, the hydraulic module 1 further includes a display panel assembly 400. The display panel assembly 400 is arranged on the side of the first panel 300 facing away from the accommodating cavity 110 and is fixedly connected to the first panel 300. The display panel assembly 400 is configured to display an operating state and data of the hydraulic module 1 (e.g., a water outlet temperature of the hydraulic module 1) and to regulate and control the hydraulic module 1 in response to a user operation (such as a touch operation).

[0033] For example, one side of the housing 100 in a thickness direction (i.e., a front-rear direction as shown in FIG. 1) is open, to form an opening. The first panel 300 is connected to a front side of the housing 100, and the display panel assembly 400 is arranged on a front side of the first panel 300.

[0034] For example, the first panel 300 is detachably mounted on the side of the housing 100 in the thickness direction, and the display panel assembly 400 is detachably mounted on the side of the first panel 300 facing away from the accommodating cavity 110.

[0035] In some embodiments, the display panel assembly 400 is arranged on the side of the housing 100 facing away from the first panel 300, and is electrically connected to the electric control box in the housing 100.

[0036] In some embodiments, as shown in FIG. 1 and FIG. 2, the hydraulic module 1 further includes a water pump 200 and a heat exchanger 210. The water pump 200 and the heat exchanger 210 are both arranged in the accommodating cavity 110. The water pump 200 is connected to the heat exchanger 210, and is configured to deliver water to the heat exchanger 210. The heat exchanger 210 is further connected to a refrigerant loop of the air conditioner and is configured to exchange heat between a refrigerant in the refrigerant loop of the air conditioner and the water flowing through the heat exchanger 210, thereby increasing or decreasing a temperature of the water, so that the hydraulic module 1 outputs the water at the set temperature.

[0037] In some embodiments, the water pump 200 is connected to an external water source.

[0038] In some embodiments, referring to FIG. 2, the heat exchanger 210 includes a first heat exchange pipeline and a first connecting pipe 211. One end of the first heat exchange pipeline is connected to the water pump 200 through the first connecting pipe 211, and is configured to convey to-be-treated water supplied by the water pump 200.

[0039] In some embodiments, referring to FIG. 2, the heat exchanger 210 further includes a second heat exchange pipeline and a second connecting pipe 212. The second heat exchange pipeline is connected to the refrigerant loop of the air conditioner through the second connecting pipe 212, and is configured to convey the refrigerant. The second heat exchange pipeline is further configured to perform heat exchange with the first heat exchange pipeline (i.e., the refrigerant in the second heat exchange pipeline performs heat exchange with the to-be-treated water in the first heat exchange pipeline) to increase or decrease the temperature of the to-be-treated water conveyed in the first heat exchange pipeline 211, so that the hydraulic module 1 outputs the water at the set temperature.

[0040] For example, a water inlet of the hydraulic module 1 is connected to a water source, and a water outlet of the hydraulic module 1 is connected to a water storage apparatus such as a water tank or a heat release apparatus such as a floor heating pipe or a radiator. The hydraulic module 1 may heat the water by performing heat exchange between the refrigerant and the water through the heat exchanger 210, or cool the water to output the water at the set temperature and deliver the water to the water storage apparatus such as the water tank or the heat release apparatus such as the floor heating pipe or radiator.

[0041] In some embodiments, as shown in FIG. 4, the hydraulic module 1 further includes an electric control box 220, and the electric control box 220 is mounted in the accommodating cavity 110, and is electrically connected to the water pump 200. The display panel assembly 400 is electrically connected to the electric control box 220.

[0042] In some embodiments, as shown in FIG. 2 and FIG. 4, the hydraulic module 1 further includes a heater 230. The heater 230 is connected to the heat exchanger. The heater 230 is connected to the other end of the first heat exchange pipeline, and is configured to heat the water in the first heat exchange pipeline. For example, the heater 230 is an electric heating tank.

[0043] For example, the heater 230 includes a liquid inlet pipe 231. The liquid inlet pipe 231 is connected to the other end of the first heat exchange pipeline.

[0044] For example, the heater 230 further includes a liquid outlet pipe 232. The liquid outlet pipe 232 is connected to the water outlet of the hydraulic module 1, so that the water can enter the liquid inlet pipe 231 from the water pump 200 through the first connecting pipe 211 and the first heat exchange pipeline, and then enter the heater 230 through the liquid inlet pipe 231. After the heater 230 heats the water flowing therethrough, the water is discharged to the water outlet of the hydraulic module 1 through the liquid outlet pipe 232. For example, the heater 230 is an electric heating tank.

[0045] It may be understood that when the refrigerant in the second heat exchange pipeline cannot provide enough heat to make the water in the first heat exchange pipeline reach the set temperature, that is, when the air conditioner performs indoor heating and the water temperature cannot meet a heating requirement, the water can be heated by the heater 230 to increase the water temperature to meet the heating requirement of the air conditioner.

[0046] In some embodiments, the heater is arranged on an outer peripheral surface of the liquid inlet pipe 231. For example, the heater 230 is a heating wire. The heating wire is wound around the outer peripheral surface of the liquid inlet pipe 231 so as to be in full contact with the liquid inlet pipe 231. In this way, the heating wire can efficiently heat the water in the liquid inlet pipe 231.

[0047] In some embodiments, the heater may alternatively be arranged on an outer peripheral surface of another pipeline in the hydraulic module 1 (e.g., the connecting pipe of the water pump), which is not limited in the present disclosure.

[0048] In some embodiments, as shown in FIG. 2 and FIG. 4, the hydraulic module 1 further includes an expander 240. The expander 240 is connected to a water outlet pipe of the heater 230, and is configured to balance air pressure in the water outlet pipe, to improve steadiness and smoothness of water output.

[0049] It may be understood that the accommodating cavity 110 may accommodate and fix a plurality of components (such as the water pump 200, the heat exchanger 210, the electric control box 220, the heater 230, and the expander 240), and the housing 100 covers the plurality of components, thereby preventing damage to the plurality of components by an external force.

[0050] Based on the separate arrangement of the housing 100, the first panel 300, and the display panel assembly 400, the display panel assembly 400 and the first panel 300 may be assembled and fixed in advance. In this way, when the hydraulic module 1 is assembled, the components such as the heat exchanger 210 and the electric control box 220 may be first mounted in the housing 100, the display panel assembly 400 and the electric control box 220 are electrically connected, and then the first panel 300, the display panel assembly 400, and the housing 100 are assembled, to seal the accommodating cavity 110. This facilitates the wiring of the display panel assembly 400 and the electric control box 220 during assembly, and also helps to simplify assembly steps of the hydraulic module 1, thereby improving assembly efficiency of the hydraulic module 1.

[0051] In addition, by arranging the first panel 300 and the housing 100 separately, when the hydraulic module 1 is maintained or repaired, the components inside the housing 100 can be exposed only by disassembling the first panel 300 from the housing 100, thereby facilitating maintenance and repair. When the wiring of the display panel assembly 400 and the electric control box 220 is inspected, wiring harnesses of the display panel assembly 400 and the electric control box 220 can be exposed only by removing the display panel assembly 400 from the first panel 300, thereby facilitating inspection of the wiring harnesses.

[0052] In some embodiments, as shown in FIG. 1 and FIG. 5, the display panel assembly 400 includes a second panel 410.

[0053] In some embodiments, the first panel 300 includes a first panel body 301 and a mounting portion 310, and the mounting portion 310 is arranged on the side of the first panel body 301 facing away from the housing 100. The second panel 410 is detachably arranged in the mounting portion 310.

[0054] For example, the first panel 300 is a sheet metal part, and the second panel 410 and the decorative plate 420 are plastic parts.

[0055] In some embodiments, as shown in FIG. 1 and FIG. 5, the display panel assembly 400 includes the decorative plate 420. The decorative plate 420 is detachably mounted on the side of the second panel 410 facing away from the first panel 300.

[0056] In some embodiments, as shown in FIG. 1 and FIG. 5, the display panel assembly 400 includes a display panel 430. The display panel 430 is detachably mounted on the side of the decorative panel 420 facing away from the second panel 410. The display panel 430 is electrically connected to the electric control box 220.

[0057] It may be understood that, through the arrangement of the decorative plate 420 in the display panel assembly 400, aesthetics of the hydraulic module 1 can be improved. For example, a color of the decorative plate 420 may be different from that of the first panel 300, or a pattern may be engraved on the decorative plate 420.

[0058] For example, the display panel 430 is a touch screen. In this way, the display panel 430 may be configured to display an operating state and data of the hydraulic module 1, and may regulate and control the hydraulic module 1 in response to a touch operation of a user.

[0059] In some embodiments, as shown in FIG. 1, a side surface of the first panel 300 facing away from the housing 100, a side surface of the second panel 410 facing away from the first panel 300, a side surface of the decorative plate 420 facing away from the second panel 410, and a side surface of the display panel 430 facing away from the decorative plate 420 are flush. In this way, flatness of an outer surface of the hydraulic module 1 can be improved, thereby improving the aesthetics of the hydraulic module 1.

[0060] For example, the mounting portion 310 is recessed towards the housing 100. That is, the mounting portion 310 is recessed in the direction away from the second panel 410. In this way, the display panel assembly 400 can be flush with an outer surface of the first panel 300 after being mounted in the mounting portion 310.

[0061] It may be understood that, through the arrangement of the mounting portion 310 in the first panel 300, the assembly between the display panel assembly 400 and the first panel 300 can be pre-positioned to simplify assembly steps of the display panel assembly 400 and the first panel 300, and a contact area between the display panel assembly 400 and the mounting portion 310 can be increased, thereby helping to improve reliability of the connection between the second panel 410 and the mounting portion 310.

[0062] In some embodiments, as shown in FIG. 2, FIG. 3, and FIG. 6, the housing 100 includes a housing body 102 and a plurality of plug-in holes 120. The plurality of plug-in holes 120 are arranged on the side of the housing body 102 close to the display panel assembly 400.

[0063] The first panel 300 includes a first panel body 301 and a plurality of plug-in blocks 320. The plurality of plug-in blocks 320 are arranged on the side of the first panel body 301 facing the housing 100. The plurality of plug-in blocks 320 correspond to a plurality of plug-in holes 120, and the plug-in blocks 320 are configured to be connected to the corresponding plug-in holes.

[0064] In this way, the first panel 300 and the housing 100 may be positioned and connected through the plug-in block 320 and the plug-in hole 120, thereby helping to simplify assembly steps between the first panel 300 and the housing 100 and improve assembly efficiency.

[0065] In some embodiments, as shown in FIG. 3, the plug-in hole 120 includes an insertion section 121, a transition section 122, and a locking section 123. Along a height direction of the hydraulic module 1 (i.e., the up-down direction as shown in FIG. 1 and FIG. 3), the insertion section 121, the transition section 122 and the locking section 123 are sequentially arranged. Moreover, the insertion section 121 is in communication with the transition section 122, and the transition section 122 is in communication with the locking section 123.

[0066] For example, the insertion section 121 extends along the height direction of the hydraulic module 1. A dimension of the insertion section 121 in the height direction of the hydraulic module 1 is greater than that of the plug-in block 320 in the height direction of the hydraulic module 1, and a dimension of the insertion section 121 in the width direction of the hydraulic module 1 (i.e., the left-right direction as shown in FIG. 1 and FIG. 3) is greater than or equal to that of the plug-in block 320 in the width direction of the hydraulic module 1. That is, the plug-in block 320 may be inserted into the insertion section 121 along the front-back direction.

[0067] For example, the transition section 122 is connected to a lower side of the insertion section 121 and extends in the direction away from the insertion section 121. Along an extension direction of the transition section 122, a width of the transition section 122 decreases. That is, a width of the end of the transition section 122 close to the insertion section 121 is greater than that of the end of the transition section 122 away from the insertion section 121. The locking section 123 is connected to a lower side of the transition section 122. A dimension of the locking section 123 in the width direction of the hydraulic module 1 is smaller than or equal to that of the transition section 122 in the width direction of the hydraulic module 1.

[0068] In some embodiments, as shown in FIG. 6, the plug-in block 320 extends in the direction close to the housing 100 and is bent towards the lower side. That is, the plug-in block 320 may be configured in a hook-like shape. In this way, the plug-in block 320 can be inserted into the plug-in hole 120 through the insertion section 121, and the insertion section 121 has a larger dimension, which facilitates the insertion of the plug-in block 320, thereby improving assembly efficiency of the first panel 300 and the housing 100. Then, under the action of gravity, the first panel 300 may slide downwards, thereby driving the plug-in block 320 to slide along the transition section 122 into the locking section 123, and the locking section 123 may limit the plug-in block 320 in the width direction of the hydraulic module 1, thereby preventing relative shaking between the first panel 300 and the housing 100. Moreover, when the plug-in block 320 is locked in the locking section 123, the end of the plug-in block 320 away from the first panel body 301 is engaged with the side of the housing 100 facing away from the first panel 300, so that the first panel 300 can be limited in the thickness direction of the hydraulic module 1, thereby realizing a fixed connection between the first panel 300 and the housing 100.

[0069] In some embodiments, as shown in FIG. 2, FIG. 3, and FIG. 5, the housing 100 includes a first side plate 130, a second side plate 140, a plurality of first guide blocks 131, and a plurality of second guide blocks 141.

[0070] The first side plate 130 and the second side plate 140 are arranged opposite to each other along the width direction of the hydraulic module 1. The plurality of first guide blocks 131 are arranged on the side of the first side plate 130 facing the display panel assembly 400, and the plurality of second guide blocks 141 are arranged on the side of the second side plate 140 facing the display panel assembly 400. The plurality of first guide blocks 131 correspond to the plurality of second guide blocks 141. Along an arrangement direction from the housing 100 to the first panel 300, a distance between the first guide block 131 and the second guide block 141 decreases, that is, a distance between the end of the first guide block 131 away from the housing 100 and the end of the second guide block 141 away from the housing 100 is smaller than that between the end of the first guide block 131 close to the housing 100 and the end of the second guide block 141 close to the housing 100. The first guide block 131 and the second guide block 141 are configured to limit the first panel 300 in the width direction of the hydraulic module 1 to improve the assembly efficiency of the first panel 300 and the housing 100.

[0071] In some embodiments, as shown in FIG. 5 and FIG. 6, the first panel 300 further includes a first side edge 330 and a second side edge 340. The first side edge 330 and the second side edge 340 are arranged opposite to each other along the width direction of the hydraulic module 1. The first guide block 131 and the second guide block 141 are located between the first side edge 330 and the second side edge 340, the first guide block 131 abuts against the first side edge 330, and the second guide block 141 abuts against the second side edge 340, so that the first panel 300 can be limited in the width direction of the hydraulic module 1.

[0072] In this case, one part of the plurality of plug-in holes 120 are arranged on the side of the first side plate 130 facing the display panel assembly 400, and the other part of the plurality of plug-in holes 120 are arranged on the side of the second side plate 140 facing the display panel assembly 400.

[0073] It may be understood that, when the first panel 300 is mounted on the housing 100, the first panel 300 is required to be moved from front to back to insert the plug-in block 320 into the plug-in hole 120. Since the distance between the end of the first guide block 131 away from the housing 100 and the end of the second guide block 141 away from the housing 100 is smaller, the first guide block 131 and the second guide block 141 can be inserted between the first side edge 330 and the second side edge 340. Then, as the first panel 300 moves towards the housing 100, the first guide block 131 may abut against the first side edge 330, and the second guide block 141 may abut against the second side edge 340, so that the first panel 300 can be limited in the width direction of the hydraulic module 1 to guide the assembly of the first panel 300 and the housing 100. In this way, assembly steps of the first panel 300 and the housing 100 are simplified, and assembly efficiency of the first panel 300 and the housing 100 is improved.

[0074] In some embodiments, as shown in FIG. 5 and FIG. 7, the housing 100 further includes a bottom plate 150 and a plurality of first bolt holes 151. The plurality of first bolt holes 151 are arranged at the end of the bottom plate 150 close to the display panel assembly 400 and are spaced apart along the width direction of the hydraulic module. For example, the first bolt hole 151 passes through the bottom plate 150 along the thickness direction of the bottom plate 150, or the first bolt hole 151 may be constructed as a blind hole.

[0075] As shown in FIG. 8 and FIG. 9, the first panel 300 further includes a first bent portion 350 and a plurality of second bolt holes 351, and the first bent portion 350 is arranged at a lower end of the first panel body and is bent towards the housing 100. The plurality of second bolt holes 351 are arranged in the first bent portion 350 and are spaced apart along the width direction of the hydraulic module.

[0076] The bottom plate 150 is located on a lower side of the first bent portion 350, and abuts against the first bent portion 350. The plurality of first bolt holes 151 correspond to the plurality of second bolt holes 351. Fasteners such as bolts pass through the first bolt hole 151 and the corresponding second bolt hole 351, so that the fixed connection between the first panel 300 and the housing 100 can be realized.

[0077] It may be understood that the arrangement of the first bent portion 350 can increase a contact area between the first panel 300 and the bottom plate 150, thereby improving stability and reliability of the connection between the first panel 300 and the housing 100. In addition, by bending the first bent portion 350 in the direction close to the housing 100, the first bent portion 350 may not protrude from the outer surface of the hydraulic module 1, thereby helping to improve reliability of a connection structure between the first panel 300 and the housing 100 and improve the aesthetics of the hydraulic module 1.

[0078] Therefore, the first panel 300 and the housing 100 can first be plugged in and fixed through the plug-in block 320 and the plug-in hole 120, and then the first panel 300 and the bottom plate 150 of the housing 100 are fixed by screwing, which can improve the assembly efficiency of the first panel 300 and the housing 100 and also ensure reliability of the connection between the first panel 300 and the housing 100.

[0079] In some embodiments, as shown in FIG. 5, the housing 100 further includes a top plate 160, and the housing is a split part. The first side plate 130, the second side plate 140, and a rear side wall of the housing 100 may be constructed as a frame by integral stamping, and the top plate 160 and the bottom plate 150 may be detachably connected to the frame respectively. This facilitates processing and assembly of the housing 100.

[0080] In some embodiments, the housing 100 may alternatively be an integral part. The first panel 300 is detachably connected to the housing 100, and seals the opening on the front side of the housing 100.

[0081] In some embodiments, as shown in FIG. 5, FIG. 10, and FIG. 11, the second panel 410 includes a second panel body 4100, a plurality of first positioning blocks 411, and a plurality of first elastic buckles 412. The plurality of first positioning blocks 411 are spaced part on an upper side surface of the second panel body 4100, and the plurality of first elastic buckles 412 are spaced part on the upper side surface of the second panel body 4100. For example, the plurality of first positioning blocks 411 and the plurality of first elastic buckles 412 are alternately spaced apart and protrude from an upper side surface of the second panel 410.

[0082] The mounting portion 310 includes a plurality of first positioning holes 311 and a plurality of first engagement holes 312. The plurality of first positioning holes 311 correspond to the plurality of first positioning blocks 411. The first positioning block 411 is configured to be inserted into the corresponding first positioning hole 311, to position the second panel 410 and the mounting portion 310. The plurality of first engagement holes 312 correspond to the plurality of first elastic buckles 412. The first elastic buckle 412 is configured to be inserted into the corresponding first engagement hole 312, and is engaged with and fixed to the first engagement hole 312.

[0083] Therefore, when the second panel 410 is assembled, the second panel 410 can be moved upwards from bottom to top to insert the first positioning block 411 into the first positioning hole 311 and insert the first elastic buckle 412 into the first engagement hole 312. In this way, the second panel 410 and the first panel 300 can be pre-positioned through cooperation between the first positioning block 411 and the first positioning block 411, so as to simplify assembly steps of the first panel 300 and the second panel 410. Moreover, after the first positioning block 411 is inserted into the first positioning hole 311, the first elastic buckle 412 may be inserted into the first engagement hole 312 and be engaged with and fixed to the first engagement hole 312, thereby preliminarily fixing the first panel 300 and the second panel 410 to prevent detachment of the second panel 410 from the first panel 300.

[0084] In some embodiments, the first panel 300 and the housing 100 are fixedly connected by welding, thereby improving reliability of the connection structure between the first panel 300 and the housing 100.

[0085] In some embodiments, the first panel 300 and the housing 100 are fixedly connected by a rivet, thereby improving reliability of the connection structure between the first panel 300 and the housing 100.

[0086] In some embodiments, one end of the first panel 300 is hinged to the housing 100, and the other end of the first panel 300 is engaged with the housing 100, thereby facilitating the opening of the first panel 300 for maintenance of the components inside the housing 100.

[0087] In some embodiments, as shown in FIG. 6, FIG. 10, and FIG. 11, the mounting portion 310 further includes a plurality of second positioning holes 313. The second panel 410 further includes a plurality of second positioning blocks 413 corresponding to the plurality of second positioning holes 313. The plurality of second positioning blocks 413 are arranged on the side of the second panel body 4100 facing the first panel 300. The second positioning block 413 includes a positioning portion 414 and an engagement portion 415.

[0088] The positioning portion 414 protrudes from a side surface of the second panel body 4100 facing the first panel 300, and the engagement portion 415 is arranged on the side of the positioning portion 414 facing away from the second panel body 4100 and protrudes from a side surface of the positioning portion 414 facing away from the second panel body 4100. In this way, when the first positioning block 411 is inserted into the first positioning hole 311, two sides of the positioning portion 414 abut against an inner wall surface of the second positioning hole 313, and the engagement portion 415 is engaged with the mounting portion 310.

[0089] For example, the first positioning block 411 is arranged in the first positioning hole 311, two sides of the positioning portion 414 along the width direction of the hydraulic module 1 abut against two side inner wall surfaces of the second positioning hole 313 along the width direction of the hydraulic module 1, and the engagement portion 415 is engaged with the side of the mounting portion 310 facing away from the display panel assembly 400.

[0090] In this way, sidewalls of the second positioning hole 313 can limit the second positioning block 413 from opposite sides thereof in the width direction, thereby limiting the second panel 410 in a width direction thereof and preventing shaking of the second panel 410 relative to the first panel 300 in the width direction, so that the connection between the first panel 300 and the second panel 410 is more stable.

[0091] In some embodiments, a dimension of the second positioning hole 313 along the height direction of the hydraulic module 1 is larger than that of the second positioning block 413 along the height direction of the hydraulic module 1, so that the second positioning block 413 can be inserted into the second positioning hole 313.

[0092] In this way, when the second panel 410 is assembled, the second panel 410 can be mounted on the first panel 300 from front to back so that the second positioning block 413 is inserted into the second positioning hole 313, and then the second panel 410 is moved upwards so that the first positioning block 411 is inserted into the first positioning hole 311 and the first elastic buckle 412 is inserted into the first engagement hole 312. In this case, the engagement portion 415 of the second positioning block 413 can be engaged with the side of the mounting portion 310 facing away from the display panel assembly 400. Therefore, the cooperation between the first elastic buckle 412 and the first engagement hole 312 can prevent detachment of the second panel 410 from the first panel 300 in the up-down direction, and the engagement of the engagement portion 415 of the second positioning block 413 with the mounting portion 310 can prevent detachment of the second panel 410 from the first panel 300 in the front-rear direction.

[0093] In some embodiments, as shown in FIG. 11, the second panel 410 further includes a plurality of third bolt holes 416. The plurality of third bolt holes 416 are spaced apart at the bottom of the second panel body 4100. For example, the plurality of third bolt holes 416 are arranged along the width direction of the hydraulic module 1.

[0094] As shown in FIG. 6 and FIG. 9, the first panel 300 further includes a second bent portion 360 and a plurality of fourth bolt holes 361. The second bent portion 360 is arranged at the lower end of the first panel body and is bent in the direction close to the second panel 410. The plurality of fourth bolt holes 361 are arranged in the second bent portion 360 and are spaced apart along the width direction of the hydraulic module.

[0095] For example, the first panel 300 includes a plurality of second bent portions 360, and the second bent portions 360 are spaced apart at the lower end of the first panel body and are bent in the direction close to the second panel 410. The plurality of fourth bolt holes 361 are correspondingly arranged in the plurality of second bent portions 360.

[0096] The second bent portion 360 is supported on a lower side of the second panel 410, and the plurality of third bolt holes 416 and the plurality of fourth bolt holes 361 are correspondingly fixedly connected by fasteners such as bolts.

[0097] It may be understood that the arrangement of the second bent portion 360 can increase a contact area between the first panel 300 and the second panel 410, thereby improving stability and reliability of the connection between the first panel 300 and the second panel 410.

[0098] Therefore, for the first panel 300 and the second panel 410, the first panel 300 and the second panel 410 can be first pre-positioned through cooperation between the first positioning block 411 and the first positioning hole 311, snap fitting between the first elastic buckle 412 and the first engagement hole 312, and cooperation between the second positioning block 413 and the second positioning hole 313, thereby improving assembly efficiency between the first panel 300 and the second panel 410. Then, the first panel 300 and the second panel 410 are fixed by screwing to improve reliability of the connection between the first panel 300 and the second panel 410.

[0099] In some embodiments, as shown in FIG. 10 to FIG. 12, the decorative plate 420 includes a plurality of second elastic buckles 421. The plurality of second elastic buckles 421 are arranged on the side of the decorative plate 420 close to the second panel 410, and are spaced apart along a circumferential direction of the decorative plate 420.

[0100] The second panel 410 further includes a plurality of second engagement holes 417, and the plurality of second elastic buckles 421 are correspondingly engaged with the plurality of second engagement holes 417, to connect the decorative plate 420 to the second panel 410.

[0101] In some embodiments, as shown in FIG. 1, FIG. 13, and FIG. 14, the housing 100 includes a frame 101. A front side, an upper side, and a lower side of the frame 101 are open, to facilitate mounting of internal components. The first panel 300 is arranged on the front side of the frame 101 and is connected to the frame 101, to seal an opening on the front side of the frame 101.

[0102] In some embodiments, the housing 100 further includes a top plate 160.

[0103] In some embodiments, the housing 100 further includes a bottom plate 150. The top plate 160 and the bottom plate 150 are respectively arranged on the upper side and the lower side of the frame 101, to seal openings on the upper side and the lower side of the frame 101. The frame 101 is fixedly connected to the top plate 160 and the bottom plate 150 through a plug-in structure and a screw-in structure.

[0104] For example, referring to FIG. 7, FIG. 14, and FIG. 15, the frame 101 includes at least one first plug-in portion 170 and at least one first screw-in portion 180, and at least one of the top plate 160 and the bottom plate 150 includes at least one second plug-in portion 152 and at least one second screw-in portion 153. The first plug-in portion 170 and the second plug-in portion 152 are engaged with each other, and the first screw-in portion 180 and the second screw-in portion 153 are fixedly connected by a fastener such as a bolt, thereby achieving a fixed connection of the frame 101 to the top plate 160 and the bottom plate 150.

[0105] In some embodiments, as shown in FIG. 14 to FIG. 17, the frame 101 includes a plurality of first plug-in portions 170 and a plurality of first screw-in portions 180. One part of the plurality of first plug-in portions 170 are arranged on the upper side of the frame 101 to be cooperatively plugged into the second plug-in portion 152 in the top plate 160, and the other part of the plurality of first plug-in portions 170 are arranged on the lower side of the frame 101 to be cooperatively plugged into the second plug-in portion 152 in the bottom plate 150. One part of the plurality of first screw-in portions 180 are arranged on the upper side of the frame 101 to be cooperatively plugged into the second screw-in portion 153 in the top plate 160, and the other part of the plurality of first screw-in portions 180 are arranged on the lower side of the frame 101 to be cooperatively plugged into the second screw-in portion 153 in the bottom plate 150.

[0106] In this way, screw-in portions between the top plate 160 and the frame 101 and between the bottom plate 150 and the frame 101 can be reduced, which helps to simplify an assembly process of the housing 100 and improve assembly efficiency of the housing 100.

[0107] In some embodiments, as shown in FIG. 14, FIG. 16, and FIG. 17, the frame 101 includes a back plate 190. The back plate 190 is a side plate of the frame 101 arranged opposite to the first panel 300. That is, the back plate is a rear side plate of the housing 100. The housing 100 may fit a wall through the back plate 190 to connect the hydraulic module 1 to the wall.

[0108] In some embodiments, as shown in FIG. 14, FIG. 16, and FIG. 17, the frame 101 further includes a first side plate 130.

[0109] In some embodiments, as shown in FIG. 14, FIG. 16, and FIG. 17, the frame 101 further includes a second side plate 140. The first side plate 130 and the second side plate 140 are respectively connected to two sides of the back plate 190 (i.e., the two sides in the width direction of the hydraulic module 1). For example, the first side plate 130 may be connected to the left side of the back plate 190, and the second side plate 140 may be connected to the right side of the back plate 190. At least one of an upper side and a lower side of the first side plate 130 is bent in the direction close to the second side plate 140 to form a third bent portion 132, and at least one of an upper side and a lower side of the second side plate 140 is bent in the direction close to the first side plate 130 to form a fourth bent portion 142.

[0110] A first part of the plurality of first plug-in portions 170 and a first part of the plurality of first screw-in portions 180 are arranged on the third bent portion 132, and a second part of the plurality of first plug-in portions 170 and a second part of the plurality of first screw-in portions 180 are arranged on the fourth bent portion 142.

[0111] For example, the upper side and the lower side of the first side plate 130 are both bent in the direction close to the second side plate 140 to form two third bent portions 132. The upper side and the lower side of the second side plate 140 are both bent in the direction close to the first side plate 130 to form two fourth bent portions 142.

[0112] In this way, along the width direction of the hydraulic module 1, one end of the top plate 160 is fixedly connected to the third bent portion 132 located on the upper side of the first side plate 130, the other end of the top plate 160 is fixedly connected to the fourth bent portion 142 located on the upper side of the second side plate 140, one end of the bottom plate 150 is fixedly connected to the third bent portion 132 located on the lower side of the first side plate 130, and the other end of the bottom plate 150 is fixedly connected to the fourth bent portion 142 located on the lower side of the second side plate 140, so that the top plate 160 and the bottom plate 150 can respectively seal the upper side and the lower side of the frame 101.

[0113] Moreover, the arrangement of the third bent portion 132 and the fourth bent portion 142 facilitates the construction of the first plug-in portion 170 and the first screw-in portion 180, and can increase a contact area between the frame 101 and the top plate 160 and a contact area between the frame 101 and the bottom plate 150, thereby helping to improve reliability of the connection between the frame 101 and the top plate 160 and the connection between the frame 101 and the bottom plate 150.

[0114] In some embodiments, as shown in FIG. 14, the back plate 190, the first side plate 130, and the second side plate 140 are constructed as an integral part, which can reduce a number of parts of the housing 100 and facilitate the assembly of the housing 100, and also helps to improve structural strength of the frame 101 and improve reliability of the connection among the back plate 190, the first side plate 130, and the second side plate 140.

[0115] In some embodiments, as shown in FIG. 7 and FIG. 16, the first plug-in portion 170 is configured as a plug-in hole, and the second plug-in portion 152 is configured as a plug-in block. The plurality of first plug-in portions 170 are correspondingly engaged with the plurality of second plug-in portions 152 to connect the frame 101 to the bottom plate 150 and to connect the frame 101 to the top plate 160.

[0116] The first screw-in portion 180 and the second screw-in portion 153 are configured as bolt holes. In this way, a plurality of bolt fasteners correspondingly pass through the plurality of first screw-in portions 180 and the plurality of second screw-in portions 153, thereby achieving a fixed connection between the frame 101 and the bottom plate 150 and a fixed connection between the frame 101 and the top plate 160.

[0117] Therefore, when the housing 100 is assembled, the plug-in block may be first inserted into the plug-in hole to pre-position the assembly of the frame 101, the top plate 160, and the bottom plate 150, thereby simplifying assembly steps of the housing 100. Then, the bolt fastener passes through the first screw-in portion 180 and the second screw-in portion 153 to fixedly connect the frame 101 and the top plate 160 as well as the frame 101 and the bottom plate 150, thereby ensuring strength of the connection between the frame 101 and the top plate 160 and between the frame 101 and the bottom plate 150, which helps to improve reliability of the housing 100.

[0118] It is to be noted that the manner of fixedly connecting the first panel 300 to the housing 100 and the related structure have been described above. Details are not described herein again.

[0119] In some embodiments, as shown in FIG. 18, the back plate 190 includes a back plate body 1900 and at least one mounting hole 191. The at least one mounting hole 191 passes through the back plate body 1900 along a thickness direction of the back plate body 1900. The mounting hole 191 is configured to fit a mounting plate pre-fixed to the wall. That is, when the hydraulic module 1 is fixed to the wall, the back plate 190 may be hung on the mounting plate through the mounting hole 191, thereby preliminarily fixing the hydraulic module 1.

[0120] In some embodiments, as shown in FIG. 16 to FIG. 18, the back plate 190 further includes a flange portion 192, and the flange portion 192 is arranged around the mounting hole 191. The flange portion 192 can enhance structural strength around the mounting hole 191, thereby improving reliability of the connection between the back plate 190 and the mounting plate and preventing deformation of the back plate 190.

[0121] In some embodiments, the flange portion 192 is arranged on the side of the back panel body 1900 facing the accommodating cavity 110, which can prevent interference of the flange portion 192 with the wall, thereby facilitating the mounting.

[0122] In some embodiments, as shown in FIG. 18, the back plate 190 further includes a protruding portion 193, and the protruding portion 193 is arranged on the back plate body 1900 and protrudes towards the accommodating cavity 110, to prevent interference of the protruding portion 193 with the wall. The protruding portion 193 is located on one side of the mounting hole 191, and is configured to improve structural strength of the back plate 190.

[0123] For example, the protruding portion 193 is located on an upper side of the mounting hole 191, and extends along the width direction of the hydraulic module 1. The protruding portion 193 is arranged close to the mounting hole 191, and is spaced apart from the mounting hole 191. In this way, the protruding portion 193 can improve the structural strength of the back plate 190, thereby improving stability of the connection between the hydraulic module 1 and the wall.

[0124] In some embodiments, the back plate 190 includes a plurality of protruding portions 193, the plurality of protruding portions 193 are spaced apart on the side of the back plate body 1900 facing the accommodating cavity 110, and extension directions of the plurality of protruding portions 193 may be the same or different, which can improve stability of the connection between the back plate 190 and the wall and can also improve stability of the connection between the components in the housing 100 (such as the heat exchanger 210, the water pump 200, and the expander 240) and the back plate 190.

[0125] In some embodiments, as shown in FIG. 18, the back plate 190 includes a plurality of assembly protrusions 197, and the plurality of assembly protrusions 197 are arranged on the back plate body 1900 and are located on the side of the back plate body 1900 facing away from the accommodating cavity 110. The plurality of assembly protrusions 197 are configured to abut against the wall to prevent direct contact of the back plate body 1900 with the wall, thereby helping to improve heat dissipation efficiency of the hydraulic module. In addition, when the temperature inside the hydraulic module 1 is low, liquid droplets may precipitate on the back plate body 1900. Therefore, through the abutment of the plurality of assembly protrusions 197 against the wall, damage to the wall caused by dripping of the liquid droplets onto the wall can be prevented.

[0126] For example, the plurality of assembly protrusions 197 include four assembly protrusions 197, and the four assembly protrusions 197 are respectively arranged at edge positions of the back plate body 1900 and protrude towards the rear side. The frame 101 abuts against the wall through the four assembly protrusions 197.

[0127] In some embodiments, as shown in FIG. 2, the hydraulic module 1 further includes a drain pan 250, and the drain pan 250 is arranged in the accommodating cavity 110, and is located at the bottom of the accommodating cavity 110. The drain pan 250 is configured to receive liquid dripping from the heat exchanger 210 or other components.

[0128] In some embodiments, as shown in FIG. 18, the back plate 190 further includes a first mounting protrusion 194. The first mounting protrusion 194 is arranged on the side of the back plate body 1900 facing the accommodating cavity 110, and protrudes towards the accommodating cavity 110. The first mounting protrusion 194 is arranged close to the bottom plate 150, and extends along the width direction of the hydraulic module 1. The drain pan 250 is fixedly connected to the first mounting protrusion 194. This can improve structural strength of the back plate 190 can be improved, and help to improve reliability of the connection between the back plate 190 and the drain pan 250.

[0129] In some embodiments, as shown in FIG. 18, the back plate 190 further includes a plurality of second mounting protrusions 195, and the plurality of second mounting protrusions 195 are arranged on the side of the back plate body 1900 facing the accommodating cavity 110, and protrude towards the accommodating cavity 110. The second mounting protrusion 195 is arranged close to the first side plate 130, and is located above the first mounting protrusion 194. The expander 240 is fixedly connected to the plurality of second mounting protrusions 195. This can improve structural strength of the back plate 190, and help to improve reliability of the connection between the back plate 190 and the expander 240.

[0130] It may be understood that the expander 240 has a large volume. Therefore, by arranging the plurality of second mounting protrusions 195 and arranging the plurality of second mounting protrusions 195 respectively at two ends of the expander 240 in a length direction or a width direction, stability of the connection between the expander 240 and the back plate 190 is improved. Compared with a single second mounting protrusion 195 with a larger size, a plurality of second mounting protrusions 195 with smaller sizes are easier to process and have higher structural strength.

[0131] In some embodiments, as shown in FIG. 18, the back plate 190 further includes a third mounting protrusion 196, and the third mounting protrusion 196 is arranged on the side of the back plate body 1900 facing the accommodating cavity 110, and protrudes towards the accommodating cavity 110. The third mounting protrusion 196 is arranged close to the second side plate 140, and is located above the first mounting protrusion 194. The heat exchanger 210 is fixedly connected to the third mounting protrusion 196. This can improve structural strength of the back plate 190, and help to improve reliability of the connection between the back plate 190 and the heat exchanger 210.

[0132] Therefore, through the arrangement of the first mounting protrusion 194, the second mounting protrusion 195, and the third mounting protrusion 196, the structural strength of the back plate 190 can be improved, and the structural strength at positions where the back plate 190 is connected to the drain pan 250, the expander 240, and the heat exchanger 210 can be improved, thereby improving reliability of the connection between the back plate 190 and the drain pan 250 and between the expander 240 and the heat exchanger 210.

[0133] In some embodiments, the hydraulic module 1 further includes a mounting bracket assembly 500. The mounting bracket assembly 500 is arranged in the accommodating cavity 110 and is close to the side of the hydraulic module 1 in the width direction. The heater 230 is arranged on the mounting bracket assembly 500. For example, the mounting bracket assembly 500 is located on the side of the heat exchanger 210 close to the first side plate 130. For example, the mounting bracket assembly 500 is arranged on the first side plate 130, and corresponds to the position of the heat exchanger 210. That is, the heater 230 and the heat exchanger 210 are arranged along the width direction of the hydraulic module 1, thereby preventing interference between the heater 230 and the heat exchanger 210 and facilitating the internal layout of the hydraulic module.

[0134] In this way, the heater 230 is connected to the housing 100 through the mounting bracket assembly 500, which helps to improve stability of the connection between the heater 230 and the housing 100.

[0135] In some embodiments, the position of the mounting bracket assembly 500 is adjustable. In this way, by adjusting the position of the mounting bracket assembly 500 relative to the first side plate 130 in the front-rear direction, the position of the heater 230 relative to the first side plate 130 can be adjusted, so that the heater 230 can be spaced apart from the back plate 190.

[0136] In some embodiments, the heater 230 and other components in the hydraulic module 1 (such as the expander 240 and the pipelines) may be arranged in the front-rear direction. For example, the other components may be located between the heater 230 and the back plate 190. It may be understood that, since the mounting bracket assembly 500 is arranged on the side plate of the housing 100, the mounting bracket assembly 500 is not easy to interfere with other components in the thickness direction of the hydraulic module 1, so that the heater 230 and part of the hydraulic module 1 can be arranged in the front-rear direction, and the other part of the hydraulic module 1 can be arranged in the left-right direction, which helps to reduce the size of the housing 100 and reduce a processing cost and a material cost of the housing 100.

[0137] In some embodiments, as shown in FIG. 2, the heat exchanger 210 is arranged on the back plate 190, and is close to the second side plate 193. The mounting bracket assembly 500 may be mounted on the first side plate 130 to connect and fix the heater 230 to the first side plate 130. In this way, the heater 230 may be spaced apart from the back plate 190, thereby facilitating the arrangement of the heater 230 and the components connected to the back plate 190 in the front-rear direction.

[0138] It is to be noted that, in some embodiments, the mounting bracket assembly 500 may alternatively be arranged on the second side plate 193. That is, the heat exchanger 210 is arranged adjacent to the first side plate 130, and the heater 230 is arranged adjacent to the second side plate 193.

[0139] In some embodiments, as shown in FIG. 20 to FIG. 22, the mounting bracket assembly 500 includes a first bracket 510 and a second bracket 520. The first bracket 510 is connected to the first side plate 130, the second bracket 520 is detachably mounted on the first bracket 510, and the heater 230 is arranged on the second bracket 520.

[0140] That is, the mounting bracket assembly 500 is a split part. In this way, when the heater 230 is mounted in the housing 100, the first bracket 510 may be connected to the housing 100 first, the second bracket 520 may be fixedly connected to the heater 230, and then the second bracket 520 may be mounted on the first bracket 510, thereby realizing the connection and fixation between the heater 230 and the housing 100, which helps to improve assembly efficiency of the heater.

[0141] In some embodiments, the first bracket 510 is welded and fixed to the first side plate 130, and the second bracket 520 is welded and fixed to an outer peripheral surface of the heater 230, thereby improving strength of the connection between the first bracket 510 and the first side plate 130 and strength of the connection between the second bracket 520 and the heater 230, and improving stability and reliability of the connection between the heater 230 and the housing 100.

[0142] In some embodiments, as shown in FIG. 22 and FIG. 23, the first bracket 510 includes a first bracket body 5100, and the first bracket body 5100 protrudes towards the back plate 190 to form a third positioning block 513. The back plate 190 includes a positioning hole corresponding to the position of the third positioning block 513, and the third positioning block 513 is arranged in the positioning hole to limit the first bracket 510 in the left-right direction and the up-down direction, thereby pre-positioning the first bracket 510 and the housing 100 and facilitating assembly connection between the first bracket 510 and the housing 100.

[0143] In some embodiments, as shown in FIG. 22 to FIG. 24, the first bracket 510 further includes a third plug-in portion 511 and a first fixing portion 512, and the third plug-in portion 511 and the first fixing portion 512 are spaced apart on the first bracket body 5100.

[0144] The second bracket 520 includes a fourth plug-in portion 521 and a second fixing portion 522, the third plug-in portion 511 is plugged into and fits the fourth plug-in portion 521, and the first fixing portion 512 is fixedly connected to the second fixing portion 522.

[0145] In this way, the first bracket 510 and the second bracket 520 can fit each other by plug-in through the third plug-in portion 511 and the fourth plug-in portion 521, and can also be fixedly connected through the first fixing portion 512 and the second fixing portion 522, which helps to improve assembly efficiency of the first bracket 510 and the second bracket 520, and at the same time can ensure reliability of the connection between the first bracket 510 and the second bracket 520, thereby improving stability of the connection between the heater 230 and the housing 100.

[0146] In some embodiments, as shown in FIG. 22 to FIG. 24, one of the third plug-in portion 511 and the fourth plug-in portion 521 is a socket, and the other is a plug. The plug is plugged into the socket. The first fixing portion 512 and the second fixing portion 522 are both mounting holes and are fixedly connected by a fastener. In this way, a number of screw connections between the first bracket 510 and the second bracket 520 can be reduced, which helps to improve assembly efficiency of the first bracket 510 and the second bracket 520.

[0147] For example, the third plug-in portion 511 is a plug and is arranged close to one side of the first bracket 510 in a length direction, and the fourth plug-in portion 521 is a socket. The first fixing portion 512 is arranged close to the other side of the first bracket 510 in the length direction. In this way, one side of the first bracket 510 fits the second bracket 520 by plug-in, and the other side of the first bracket 510 is connected to the second bracket 520 by the fastener, which helps to improve stability of the connection between the first bracket 510 and the second bracket 520.

[0148] For example, the third plug-in portion 511 protrudes towards the second side plate 140, and an upper side and a front side of the third plug-in portion 511 are open. The fourth plug-in portion 521 may be plugged into the fourth plug-in portion 521 from top to bottom or from front to back, so that side walls of the third plug-in portion 511 can be stopped at the side of the fourth plug-in portion 521 facing the back plate 190, a lower side of the fourth plug-in portion 521, and the side of the fourth plug-in portion 521 facing away from the first bracket body 5100, thereby supporting and fixing the second bracket 520 and limiting the second bracket 520 in a thickness direction of the first bracket 510.

[0149] In some embodiments, as shown in FIG. 22 and FIG. 24, the second bracket 520 includes a vertical portion 523 and a horizontal portion 524. The vertical portion 523 fits the first bracket body 5100, and extends along the height direction of the hydraulic module 1. The horizontal portion 524 is arranged at an upper end of the vertical portion 523, and extends towards the second side plate 140. The heater 230 is arranged on the horizontal portion 524. The fourth plug-in portion 521 and the second fixing portion 522 are arranged on the vertical portion 523.

[0150] For example, the side of the horizontal portion 524 facing the second side plate 140 is welded and fixed to the heater 230. The end of the horizontal portion 524 facing the heater 230 may be constructed as an arc that matches the outer peripheral surface of the heater 230, thereby increasing a contact area between the horizontal portion 524 and the heater 230, which helps to improve strength of the connection between the second bracket 520 and the heater 230. In addition, the vertical portion 523 fits the first bracket body 5100, which can increase a contact area between the vertical portion 523 and the first bracket 510, thereby helping to improve stability of the connection between the first bracket 510 and the second bracket 520.

[0151] In some embodiments, as shown in FIG. 2 and FIG. 4, the expander 240 is located at a rear side of the heater 230 and is fixedly connected to the housing 100, and the electric control box 220 is located at a front side of the heater 230 and is fixedly connected to the housing 100.

[0152] That is, the expander 240, the heater 230, and the electric control box 220 may be arranged along the front-rear direction of the housing 100, which facilitates the layout and mounting of the expander 240, the heater 230, and the electric control box 220 and can effectively reduce the size of the housing 100.

[0153] In some embodiments, as shown in FIG. 22 and FIG. 23, the first bracket 510 further includes an avoidance groove 514. The avoidance groove 514 is arranged on the first bracket body 5100 and corresponds to the position of the expander 240. The avoidance groove 514 is recessed in the direction away from the expander 240 to avoid the expander 240, thereby preventing positional interference between the first bracket 510 and the expander 240.

[0154] In some embodiments, the first bracket 510 is located on a front side of the expander 240, that is, the first bracket 510 is connected to the first side plate 130 and is spaced apart from the back plate 190 by a predetermined distance. In this way, a dimension of the first bracket 510 in the front-rear direction can be shortened, which helps to reduce a processing cost of the first bracket 510. In addition, the first bracket 510 may not extend between the expander 240 and the first side plate 130, so there is no need to arrange the avoidance groove 514 in the first bracket 510 to avoid the expander 240, which helps to simplify the structure of the first bracket 510 and facilitates the processing.

[0155] In some embodiments, as shown in FIG. 19, the hydraulic module 1 includes a plurality of mounting bracket assemblies 500, and the plurality of mounting bracket assemblies 500 are spaced apart on the first side plate 130 along the height direction of the hydraulic module. For example, the plurality of mounting bracket assemblies 500 may be spaced apart along an axial direction of the heater 230, and the plurality of mounting bracket assemblies 500 respectively fix a plurality of axial parts of the heater 230 and the first side plate 130, which helps to improve strength of the connection between the heater 230 and the first side plate 130.

[0156] Some embodiments of the present disclosure further provide an air conditioner 1000. As shown in FIG. 25, the air conditioner 1000 includes the hydraulic module 1 in any one of the foregoing embodiments and achieves the same technical effect as the hydraulic module 1, which is not described in detail in the present disclosure.

[0157] The air conditioner 1000 performs a refrigeration cycle of the air conditioner 1000 by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplying a refrigerant to exchange heat with the conditioned air.

[0158] The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges a compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to a surrounding environment through a condensation process.

[0159] The expansion valve expands a high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by utilizing latent heat of evaporation of the refrigerant to exchange heat with a to-be-cooled material. In the entire cycle, the air conditioner 1000 may regulate a temperature and humidity of an indoor space.

[0160] Those skilled in the art will understand that the scope of disclosure in the present invention is not limited to the foregoing specific embodiments and may modify and substitute some elements of the embodiments without departing from the spirits of the present disclosure. The scope of the present disclosure is limited by the appended claims.

[0027] A hydraulic module is an integrated circulating water delivery device commonly used in air conditioners, which enables hot water preparation by using a refrigerant from an air conditioning system by connecting a water heating pipeline to the air conditioning system.

[0028] The hydraulic module typically includes a housing, a display panel, and an electric control box. The display panel is mounted on an outer surface of the housing and is electrically connected to the electric control box arranged inside the housing. However, if an internal structure of the hydraulic module is not properly configured, assembly between the display panel and the housing may be complicated, thereby reducing assembly efficiency of the hydraulic module. This makes wiring of the display panel and the electric control box inconvenient, and also makes maintenance and repair of components inside the hydraulic module inconvenient.

[0029] Accordingly, some embodiments of the present disclosure provide a hydraulic module 1. The hydraulic module 1 can be applied to air conditioners, or may be applied to floor heating, radiators, or other domestic heating devices, and is configured to heat or cool water flowing therethrough to output water at a set temperature.

[0030] In some embodiments, as shown in FIG. 1, the hydraulic module 1 includes a housing 100. One side of the housing 100 is open to form an opening. For example, the housing 100 is substantially a lidless cuboid.

[0031] In some embodiments, as shown in FIG. 1, the hydraulic module 1 further includes a first panel 300. The first panel 300 is fixedly connected to the housing 100, and seals the opening. The housing 100 and the first panel 300 together define an accommodating cavity 110. For example, the first panel 300 is in a shape of a rectangle.

[0032] In some embodiments, as shown in FIG. 1, the hydraulic module 1 further includes a display panel assembly 400. The display panel assembly 400 is arranged on the side of the first panel 300 facing away from the accommodating cavity 110 and is fixedly connected to the first panel 300. The display panel assembly 400 is configured to display an operating state and data of the hydraulic module 1 (e.g., a water outlet temperature of the hydraulic module 1) and to regulate and control the hydraulic module 1 in response to a user operation (such as a touch operation).

[0033] For example, one side of the housing 100 in a thickness direction (i.e., a front-rear direction as shown in FIG. 1) is open, to form an opening. The first panel 300 is connected to a front side of the housing 100, and the display panel assembly 400 is arranged on a front side of the first panel 300.

[0034] For example, the first panel 300 is detachably mounted on the side of the housing 100 in the thickness direction, and the display panel assembly 400 is detachably mounted on the side of the first panel 300 facing away from the accommodating cavity 110.

[0035] In some embodiments, the display panel assembly 400 is arranged on the side of the housing 100 facing away from the first panel 300, and is electrically connected to the electric control box in the housing 100.

[0036] In some embodiments, as shown in FIG. 1 and FIG. 2, the hydraulic module 1 further includes a water pump 200 and a heat exchanger 210. The water pump 200 and the heat exchanger 210 are both arranged in the accommodating cavity 110. The water pump 200 is connected to the heat exchanger 210, and is configured to deliver water to the heat exchanger 210. The heat exchanger 210 is further connected to a refrigerant loop of the air conditioner and is configured to exchange heat between a refrigerant in the refrigerant loop of the air conditioner and the water flowing through the heat exchanger 210, thereby increasing or decreasing a temperature of the water, so that the hydraulic module 1 outputs the water at the set temperature.

[0037] In some embodiments, the water pump 200 is connected to an external water source.

[0038] In some embodiments, referring to FIG. 2, the heat exchanger 210 includes a first heat exchange pipeline and a first connecting pipe 211. One end of the first heat exchange pipeline is connected to the water pump 200 through the first connecting pipe 211, and is configured to convey to-be-treated water supplied by the water pump 200.

[0039] In some embodiments, referring to FIG. 2, the heat exchanger 210 further includes a second heat exchange pipeline and a second connecting pipe 212. The second heat exchange pipeline is connected to the refrigerant loop of the air conditioner through the second connecting pipe 212, and is configured to convey the refrigerant. The second heat exchange pipeline is further configured to perform heat exchange with the first heat exchange pipeline (i.e., the refrigerant in the second heat exchange pipeline performs heat exchange with the to-be-treated water in the first heat exchange pipeline) to increase or decrease the temperature of the to-be-treated water conveyed in the first heat exchange pipeline 211, so that the hydraulic module 1 outputs the water at the set temperature.

[0040] For example, a water inlet of the hydraulic module 1 is connected to a water source, and a water outlet of the hydraulic module 1 is connected to a water storage apparatus such as a water tank or a heat release apparatus such as a floor heating pipe or a radiator. The hydraulic module 1 may heat the water by performing heat exchange between the refrigerant and the water through the heat exchanger 210, or cool the water to output the water at the set temperature and deliver the water to the water storage apparatus such as the water tank or the heat release apparatus such as the floor heating pipe or radiator.

[0041] In some embodiments, as shown in FIG. 4, the hydraulic module 1 further includes an electric control box 220, and the electric control box 220 is mounted in the accommodating cavity 110, and is electrically connected to the water pump 200. The display panel assembly 400 is electrically connected to the electric control box 220.

[0042] In some embodiments, as shown in FIG. 2 and FIG. 4, the hydraulic module 1 further includes a heater 230. The heater 230 is connected to the heat exchanger. The heater 230 is connected to the other end of the first heat exchange pipeline, and is configured to heat the water in the first heat exchange pipeline. For example, the heater 230 is an electric heating tank.

[0043] For example, the heater 230 includes a liquid inlet pipe 231. The liquid inlet pipe 231 is connected to the other end of the first heat exchange pipeline.

[0044] For example, the heater 230 further includes a liquid outlet pipe 232. The liquid outlet pipe 232 is connected to the water outlet of the hydraulic module 1, so that the water can enter the liquid inlet pipe 231 from the water pump 200 through the first connecting pipe 211 and the first heat exchange pipeline, and then enter the heater 230 through the liquid inlet pipe 231. After the heater 230 heats the water flowing therethrough, the water is discharged to the water outlet of the hydraulic module 1 through the liquid outlet pipe 232. For example, the heater 230 is an electric heating tank.

[0045] It may be understood that when the refrigerant in the second heat exchange pipeline cannot provide enough heat to make the water in the first heat exchange pipeline reach the set temperature, that is, when the air conditioner performs indoor heating and the water temperature cannot meet a heating requirement, the water can be heated by the heater 230 to increase the water temperature to meet the heating requirement of the air conditioner.

[0046] In some embodiments, the heater is arranged on an outer peripheral surface of the liquid inlet pipe 231. For example, the heater 230 is a heating wire. The heating wire is wound around the outer peripheral surface of the liquid inlet pipe 231 so as to be in full contact with the liquid inlet pipe 231. In this way, the heating wire can efficiently heat the water in the liquid inlet pipe 231.

[0047] In some embodiments, the heater may alternatively be arranged on an outer peripheral surface of another pipeline in the hydraulic module 1 (e.g., the connecting pipe of the water pump), which is not limited in the present disclosure.

[0048] In some embodiments, as shown in FIG. 2 and FIG. 4, the hydraulic module 1 further includes an expander 240. The expander 240 is connected to a water outlet pipe of the heater 230, and is configured to balance air pressure in the water outlet pipe, to improve steadiness and smoothness of water output.

[0049] It may be understood that the accommodating cavity 110 may accommodate and fix a plurality of components (such as the water pump 200, the heat exchanger 210, the electric control box 220, the heater 230, and the expander 240), and the housing 100 covers the plurality of components, thereby preventing damage to the plurality of components by an external force.

[0050] Based on the separate arrangement of the housing 100, the first panel 300, and the display panel assembly 400, the display panel assembly 400 and the first panel 300 may be assembled and fixed in advance. In this way, when the hydraulic module 1 is assembled, the components such as the heat exchanger 210 and the electric control box 220 may be first mounted in the housing 100, the display panel assembly 400 and the electric control box 220 are electrically connected, and then the first panel 300, the display panel assembly 400, and the housing 100 are assembled, to seal the accommodating cavity 110. This facilitates the wiring of the display panel assembly 400 and the electric control box 220 during assembly, and also helps to simplify assembly steps of the hydraulic module 1, thereby improving assembly efficiency of the hydraulic module 1.

[0051] In addition, by arranging the first panel 300 and the housing 100 separately, when the hydraulic module 1 is maintained or repaired, the components inside the housing 100 can be exposed only by disassembling the first panel 300 from the housing 100, thereby facilitating maintenance and repair. When the wiring of the display panel assembly 400 and the electric control box 220 is inspected, wiring harnesses of the display panel assembly 400 and the electric control box 220 can be exposed only by removing the display panel assembly 400 from the first panel 300, thereby facilitating inspection of the wiring harnesses.

[0052] In some embodiments, as shown in FIG. 1 and FIG. 5, the display panel assembly 400 includes a second panel 410.

[0053] In some embodiments, the first panel 300 includes a first panel body 301 and a mounting portion 310, and the mounting portion 310 is arranged on the side of the first panel body 301 facing away from the housing 100. The second panel 410 is detachably arranged in the mounting portion 310.

[0054] For example, the first panel 300 is a sheet metal part, and the second panel 410 and the decorative plate 420 are plastic parts.

[0055] In some embodiments, as shown in FIG. 1 and FIG. 5, the display panel assembly 400 includes the decorative plate 420. The decorative plate 420 is detachably mounted on the side of the second panel 410 facing away from the first panel 300.

[0056] In some embodiments, as shown in FIG. 1 and FIG. 5, the display panel assembly 400 includes a display panel 430. The display panel 430 is detachably mounted on the side of the decorative panel 420 facing away from the second panel 410. The display panel 430 is electrically connected to the electric control box 220.

[0057] It may be understood that, through the arrangement of the decorative plate 420 in the display panel assembly 400, aesthetics of the hydraulic module 1 can be improved. For example, a color of the decorative plate 420 may be different from that of the first panel 300, or a pattern may be engraved on the decorative plate 420.

[0058] For example, the display panel 430 is a touch screen. In this way, the display panel 430 may be configured to display an operating state and data of the hydraulic module 1, and may regulate and control the hydraulic module 1 in response to a touch operation of a user.

[0059] In some embodiments, as shown in FIG. 1, a side surface of the first panel 300 facing away from the housing 100, a side surface of the second panel 410 facing away from the first panel 300, a side surface of the decorative plate 420 facing away from the second panel 410, and a side surface of the display panel 430 facing away from the decorative plate 420 are flush. In this way, flatness of an outer surface of the hydraulic module 1 can be improved, thereby improving the aesthetics of the hydraulic module 1.

[0060] For example, the mounting portion 310 is recessed towards the housing 100. That is, the mounting portion 310 is recessed in the direction away from the second panel 410. In this way, the display panel assembly 400 can be flush with an outer surface of the first panel 300 after being mounted in the mounting portion 310.

[0061] It may be understood that, through the arrangement of the mounting portion 310 in the first panel 300, the assembly between the display panel assembly 400 and the first panel 300 can be pre-positioned to simplify assembly steps of the display panel assembly 400 and the first panel 300, and a contact area between the display panel assembly 400 and the mounting portion 310 can be increased, thereby helping to improve reliability of the connection between the second panel 410 and the mounting portion 310.

[0062] In some embodiments, as shown in FIG. 2, FIG. 3, and FIG. 6, the housing 100 includes a housing body 102 and a plurality of plug-in holes 120. The plurality of plug-in holes 120 are arranged on the side of the housing body 102 close to the display panel assembly 400.

[0063] The first panel 300 includes a first panel body 301 and a plurality of plug-in blocks 320. The plurality of plug-in blocks 320 are arranged on the side of the first panel body 301 facing the housing 100. The plurality of plug-in blocks 320 correspond to a plurality of plug-in holes 120, and the plug-in blocks 320 are configured to be connected to the corresponding plug-in holes.

[0064] In this way, the first panel 300 and the housing 100 may be positioned and connected through the plug-in block 320 and the plug-in hole 120, thereby helping to simplify assembly steps between the first panel 300 and the housing 100 and improve assembly efficiency.

[0065] In some embodiments, as shown in FIG. 3, the plug-in hole 120 includes an insertion section 121, a transition section 122, and a locking section 123. Along a height direction of the hydraulic module 1 (i.e., the up-down direction as shown in FIG. 1 and FIG. 3), the insertion section 121, the transition section 122 and the locking section 123 are sequentially arranged. Moreover, the insertion section 121 is in communication with the transition section 122, and the transition section 122 is in communication with the locking section 123.

[0066] For example, the insertion section 121 extends along the height direction of the hydraulic module 1. A dimension of the insertion section 121 in the height direction of the hydraulic module 1 is greater than that of the plug-in block 320 in the height direction of the hydraulic module 1, and a dimension of the insertion section 121 in the width direction of the hydraulic module 1 (i.e., the left-right direction as shown in FIG. 1 and FIG. 3) is greater than or equal to that of the plug-in block 320 in the width direction of the hydraulic module 1. That is, the plug-in block 320 may be inserted into the insertion section 121 along the front-back direction.

[0067] For example, the transition section 122 is connected to a lower side of the insertion section 121 and extends in the direction away from the insertion section 121. Along an extension direction of the transition section 122, a width of the transition section 122 decreases. That is, a width of the end of the transition section 122 close to the insertion section 121 is greater than that of the end of the transition section 122 away from the insertion section 121. The locking section 123 is connected to a lower side of the transition section 122. A dimension of the locking section 123 in the width direction of the hydraulic module 1 is smaller than or equal to that of the transition section 122 in the width direction of the hydraulic module 1.

[0068] In some embodiments, as shown in FIG. 6, the plug-in block 320 extends in the direction close to the housing 100 and is bent towards the lower side. That is, the plug-in block 320 may be configured in a hook-like shape. In this way, the plug-in block 320 can be inserted into the plug-in hole 120 through the insertion section 121, and the insertion section 121 has a larger dimension, which facilitates the insertion of the plug-in block 320, thereby improving assembly efficiency of the first panel 300 and the housing 100. Then, under the action of gravity, the first panel 300 may slide downwards, thereby driving the plug-in block 320 to slide along the transition section 122 into the locking section 123, and the locking section 123 may limit the plug-in block 320 in the width direction of the hydraulic module 1, thereby preventing relative shaking between the first panel 300 and the housing 100. Moreover, when the plug-in block 320 is locked in the locking section 123, the end of the plug-in block 320 away from the first panel body 301 is engaged with the side of the housing 100 facing away from the first panel 300, so that the first panel 300 can be limited in the thickness direction of the hydraulic module 1, thereby realizing a fixed connection between the first panel 300 and the housing 100.

[0069] In some embodiments, as shown in FIG. 2, FIG. 3, and FIG. 5, the housing 100 includes a first side plate 130, a second side plate 140, a plurality of first guide blocks 131, and a plurality of second guide blocks 141.

[0070] The first side plate 130 and the second side plate 140 are arranged opposite to each other along the width direction of the hydraulic module 1. The plurality of first guide blocks 131 are arranged on the side of the first side plate 130 facing the display panel assembly 400, and the plurality of second guide blocks 141 are arranged on the side of the second side plate 140 facing the display panel assembly 400. The plurality of first guide blocks 131 correspond to the plurality of second guide blocks 141. Along an arrangement direction from the housing 100 to the first panel 300, a distance between the first guide block 131 and the second guide block 141 decreases, that is, a distance between the end of the first guide block 131 away from the housing 100 and the end of the second guide block 141 away from the housing 100 is smaller than that between the end of the first guide block 131 close to the housing 100 and the end of the second guide block 141 close to the housing 100. The first guide block 131 and the second guide block 141 are configured to limit the first panel 300 in the width direction of the hydraulic module 1 to improve the assembly efficiency of the first panel 300 and the housing 100.

[0071] In some embodiments, as shown in FIG. 5 and FIG. 6, the first panel 300 further includes a first side edge 330 and a second side edge 340. The first side edge 330 and the second side edge 340 are arranged opposite to each other along the width direction of the hydraulic module 1. The first guide block 131 and the second guide block 141 are located between the first side edge 330 and the second side edge 340, the first guide block 131 abuts against the first side edge 330, and the second guide block 141 abuts against the second side edge 340, so that the first panel 300 can be limited in the width direction of the hydraulic module 1.

[0072] In this case, one part of the plurality of plug-in holes 120 are arranged on the side of the first side plate 130 facing the display panel assembly 400, and the other part of the plurality of plug-in holes 120 are arranged on the side of the second side plate 140 facing the display panel assembly 400.

[0073] It may be understood that, when the first panel 300 is mounted on the housing 100, the first panel 300 is required to be moved from front to back to insert the plug-in block 320 into the plug-in hole 120. Since the distance between the end of the first guide block 131 away from the housing 100 and the end of the second guide block 141 away from the housing 100 is smaller, the first guide block 131 and the second guide block 141 can be inserted between the first side edge 330 and the second side edge 340. Then, as the first panel 300 moves towards the housing 100, the first guide block 131 may abut against the first side edge 330, and the second guide block 141 may abut against the second side edge 340, so that the first panel 300 can be limited in the width direction of the hydraulic module 1 to guide the assembly of the first panel 300 and the housing 100. In this way, assembly steps of the first panel 300 and the housing 100 are simplified, and assembly efficiency of the first panel 300 and the housing 100 is improved.

[0074] In some embodiments, as shown in FIG. 5 and FIG. 7, the housing 100 further includes a bottom plate 150 and a plurality of first bolt holes 151. The plurality of first bolt holes 151 are arranged at the end of the bottom plate 150 close to the display panel assembly 400 and are spaced apart along the width direction of the hydraulic module. For example, the first bolt hole 151 passes through the bottom plate 150 along the thickness direction of the bottom plate 150, or the first bolt hole 151 may be constructed as a blind hole.

[0075] As shown in FIG. 8 and FIG. 9, the first panel 300 further includes a first bent portion 350 and a plurality of second bolt holes 351, and the first bent portion 350 is arranged at a lower end of the first panel body and is bent towards the housing 100. The plurality of second bolt holes 351 are arranged in the first bent portion 350 and are spaced apart along the width direction of the hydraulic module.

[0076] The bottom plate 150 is located on a lower side of the first bent portion 350, and abuts against the first bent portion 350. The plurality of first bolt holes 151 correspond to the plurality of second bolt holes 351. Fasteners such as bolts pass through the first bolt hole 151 and the corresponding second bolt hole 351, so that the fixed connection between the first panel 300 and the housing 100 can be realized.

[0077] It may be understood that the arrangement of the first bent portion 350 can increase a contact area between the first panel 300 and the bottom plate 150, thereby improving stability and reliability of the connection between the first panel 300 and the housing 100. In addition, by bending the first bent portion 350 in the direction close to the housing 100, the first bent portion 350 may not protrude from the outer surface of the hydraulic module 1, thereby helping to improve reliability of a connection structure between the first panel 300 and the housing 100 and improve the aesthetics of the hydraulic module 1.

[0078] Therefore, the first panel 300 and the housing 100 can first be plugged in and fixed through the plug-in block 320 and the plug-in hole 120, and then the first panel 300 and the bottom plate 150 of the housing 100 are fixed by screwing, which can improve the assembly efficiency of the first panel 300 and the housing 100 and also ensure reliability of the connection between the first panel 300 and the housing 100.

[0079] In some embodiments, as shown in FIG. 5, the housing 100 further includes a top plate 160, and the housing is a split part. The first side plate 130, the second side plate 140, and a rear side wall of the housing 100 may be constructed as a frame by integral stamping, and the top plate 160 and the bottom plate 150 may be detachably connected to the frame respectively. This facilitates processing and assembly of the housing 100.

[0080] In some embodiments, the housing 100 may alternatively be an integral part. The first panel 300 is detachably connected to the housing 100, and seals the opening on the front side of the housing 100.

[0081] In some embodiments, as shown in FIG. 5, FIG. 10, and FIG. 11, the second panel 410 includes a second panel body 4100, a plurality of first positioning blocks 411, and a plurality of first elastic buckles 412. The plurality of first positioning blocks 411 are spaced part on an upper side surface of the second panel body 4100, and the plurality of first elastic buckles 412 are spaced part on the upper side surface of the second panel body 4100. For example, the plurality of first positioning blocks 411 and the plurality of first elastic buckles 412 are alternately spaced apart and protrude from an upper side surface of the second panel 410.

[0082] The mounting portion 310 includes a plurality of first positioning holes 311 and a plurality of first engagement holes 312. The plurality of first positioning holes 311 correspond to the plurality of first positioning blocks 411. The first positioning block 411 is configured to be inserted into the corresponding first positioning hole 311, to position the second panel 410 and the mounting portion 310. The plurality of first engagement holes 312 correspond to the plurality of first elastic buckles 412. The first elastic buckle 412 is configured to be inserted into the corresponding first engagement hole 312, and is engaged with and fixed to the first engagement hole 312.

[0083] Therefore, when the second panel 410 is assembled, the second panel 410 can be moved upwards from bottom to top to insert the first positioning block 411 into the first positioning hole 311 and insert the first elastic buckle 412 into the first engagement hole 312. In this way, the second panel 410 and the first panel 300 can be pre-positioned through cooperation between the first positioning block 411 and the first positioning block 411, so as to simplify assembly steps of the first panel 300 and the second panel 410. Moreover, after the first positioning block 411 is inserted into the first positioning hole 311, the first elastic buckle 412 may be inserted into the first engagement hole 312 and be engaged with and fixed to the first engagement hole 312, thereby preliminarily fixing the first panel 300 and the second panel 410 to prevent detachment of the second panel 410 from the first panel 300.

[0084] In some embodiments, the first panel 300 and the housing 100 are fixedly connected by welding, thereby improving reliability of the connection structure between the first panel 300 and the housing 100.

[0085] In some embodiments, the first panel 300 and the housing 100 are fixedly connected by a rivet, thereby improving reliability of the connection structure between the first panel 300 and the housing 100.

[0086] In some embodiments, one end of the first panel 300 is hinged to the housing 100, and the other end of the first panel 300 is engaged with the housing 100, thereby facilitating the opening of the first panel 300 for maintenance of the components inside the housing 100.

[0087] In some embodiments, as shown in FIG. 6, FIG. 10, and FIG. 11, the mounting portion 310 further includes a plurality of second positioning holes 313. The second panel 410 further includes a plurality of second positioning blocks 413 corresponding to the plurality of second positioning holes 313. The plurality of second positioning blocks 413 are arranged on the side of the second panel body 4100 facing the first panel 300. The second positioning block 413 includes a positioning portion 414 and an engagement portion 415.

[0088] The positioning portion 414 protrudes from a side surface of the second panel body 4100 facing the first panel 300, and the engagement portion 415 is arranged on the side of the positioning portion 414 facing away from the second panel body 4100 and protrudes from a side surface of the positioning portion 414 facing away from the second panel body 4100. In this way, when the first positioning block 411 is inserted into the first positioning hole 311, two sides of the positioning portion 414 abut against an inner wall surface of the second positioning hole 313, and the engagement portion 415 is engaged with the mounting portion 310.

[0089] For example, the first positioning block 411 is arranged in the first positioning hole 311, two sides of the positioning portion 414 along the width direction of the hydraulic module 1 abut against two side inner wall surfaces of the second positioning hole 313 along the width direction of the hydraulic module 1, and the engagement portion 415 is engaged with the side of the mounting portion 310 facing away from the display panel assembly 400.

[0090] In this way, sidewalls of the second positioning hole 313 can limit the second positioning block 413 from opposite sides thereof in the width direction, thereby limiting the second panel 410 in a width direction thereof and preventing shaking of the second panel 410 relative to the first panel 300 in the width direction, so that the connection between the first panel 300 and the second panel 410 is more stable.

[0091] In some embodiments, a dimension of the second positioning hole 313 along the height direction of the hydraulic module 1 is larger than that of the second positioning block 413 along the height direction of the hydraulic module 1, so that the second positioning block 413 can be inserted into the second positioning hole 313.

[0092] In this way, when the second panel 410 is assembled, the second panel 410 can be mounted on the first panel 300 from front to back so that the second positioning block 413 is inserted into the second positioning hole 313, and then the second panel 410 is moved upwards so that the first positioning block 411 is inserted into the first positioning hole 311 and the first elastic buckle 412 is inserted into the first engagement hole 312. In this case, the engagement portion 415 of the second positioning block 413 can be engaged with the side of the mounting portion 310 facing away from the display panel assembly 400. Therefore, the cooperation between the first elastic buckle 412 and the first engagement hole 312 can prevent detachment of the second panel 410 from the first panel 300 in the up-down direction, and the engagement of the engagement portion 415 of the second positioning block 413 with the mounting portion 310 can prevent detachment of the second panel 410 from the first panel 300 in the front-rear direction.

[0093] In some embodiments, as shown in FIG. 11, the second panel 410 further includes a plurality of third bolt holes 416. The plurality of third bolt holes 416 are spaced apart at the bottom of the second panel body 4100. For example, the plurality of third bolt holes 416 are arranged along the width direction of the hydraulic module 1.

[0094] As shown in FIG. 6 and FIG. 9, the first panel 300 further includes a second bent portion 360 and a plurality of fourth bolt holes 361. The second bent portion 360 is arranged at the lower end of the first panel body and is bent in the direction close to the second panel 410. The plurality of fourth bolt holes 361 are arranged in the second bent portion 360 and are spaced apart along the width direction of the hydraulic module.

[0095] For example, the first panel 300 includes a plurality of second bent portions 360, and the second bent portions 360 are spaced apart at the lower end of the first panel body and are bent in the direction close to the second panel 410. The plurality of fourth bolt holes 361 are correspondingly arranged in the plurality of second bent portions 360.

[0096] The second bent portion 360 is supported on a lower side of the second panel 410, and the plurality of third bolt holes 416 and the plurality of fourth bolt holes 361 are correspondingly fixedly connected by fasteners such as bolts.

[0097] It may be understood that the arrangement of the second bent portion 360 can increase a contact area between the first panel 300 and the second panel 410, thereby improving stability and reliability of the connection between the first panel 300 and the second panel 410.

[0098] Therefore, for the first panel 300 and the second panel 410, the first panel 300 and the second panel 410 can be first pre-positioned through cooperation between the first positioning block 411 and the first positioning hole 311, snap fitting between the first elastic buckle 412 and the first engagement hole 312, and cooperation between the second positioning block 413 and the second positioning hole 313, thereby improving assembly efficiency between the first panel 300 and the second panel 410. Then, the first panel 300 and the second panel 410 are fixed by screwing to improve reliability of the connection between the first panel 300 and the second panel 410.

[0099] In some embodiments, as shown in FIG. 10 to FIG. 12, the decorative plate 420 includes a plurality of second elastic buckles 421. The plurality of second elastic buckles 421 are arranged on the side of the decorative plate 420 close to the second panel 410, and are spaced apart along a circumferential direction of the decorative plate 420.

[0100] The second panel 410 further includes a plurality of second engagement holes 417, and the plurality of second elastic buckles 421 are correspondingly engaged with the plurality of second engagement holes 417, to connect the decorative plate 420 to the second panel 410.

[0101] In some embodiments, as shown in FIG. 1, FIG. 13, and FIG. 14, the housing 100 includes a frame 101. A front side, an upper side, and a lower side of the frame 101 are open, to facilitate mounting of internal components. The first panel 300 is arranged on the front side of the frame 101 and is connected to the frame 101, to seal an opening on the front side of the frame 101.

[0102] In some embodiments, the housing 100 further includes a top plate 160.

[0103] In some embodiments, the housing 100 further includes a bottom plate 150. The top plate 160 and the bottom plate 150 are respectively arranged on the upper side and the lower side of the frame 101, to seal openings on the upper side and the lower side of the frame 101. The frame 101 is fixedly connected to the top plate 160 and the bottom plate 150 through a plug-in structure and a screw-in structure.

[0104] For example, referring to FIG. 7, FIG. 14, and FIG. 15, the frame 101 includes at least one first plug-in portion 170 and at least one first screw-in portion 180, and at least one of the top plate 160 and the bottom plate 150 includes at least one second plug-in portion 152 and at least one second screw-in portion 153. The first plug-in portion 170 and the second plug-in portion 152 are engaged with each other, and the first screw-in portion 180 and the second screw-in portion 153 are fixedly connected by a fastener such as a bolt, thereby achieving a fixed connection of the frame 101 to the top plate 160 and the bottom plate 150.

[0105] In some embodiments, as shown in FIG. 14 to FIG. 17, the frame 101 includes a plurality of first plug-in portions 170 and a plurality of first screw-in portions 180. One part of the plurality of first plug-in portions 170 are arranged on the upper side of the frame 101 to be cooperatively plugged into the second plug-in portion 152 in the top plate 160, and the other part of the plurality of first plug-in portions 170 are arranged on the lower side of the frame 101 to be cooperatively plugged into the second plug-in portion 152 in the bottom plate 150. One part of the plurality of first screw-in portions 180 are arranged on the upper side of the frame 101 to be cooperatively plugged into the second screw-in portion 153 in the top plate 160, and the other part of the plurality of first screw-in portions 180 are arranged on the lower side of the frame 101 to be cooperatively plugged into the second screw-in portion 153 in the bottom plate 150.

[0106] In this way, screw-in portions between the top plate 160 and the frame 101 and between the bottom plate 150 and the frame 101 can be reduced, which helps to simplify an assembly process of the housing 100 and improve assembly efficiency of the housing 100.

[0107] In some embodiments, as shown in FIG. 14, FIG. 16, and FIG. 17, the frame 101 includes a back plate 190. The back plate 190 is a side plate of the frame 101 arranged opposite to the first panel 300. That is, the back plate is a rear side plate of the housing 100. The housing 100 may fit a wall through the back plate 190 to connect the hydraulic module 1 to the wall.

[0108] In some embodiments, as shown in FIG. 14, FIG. 16, and FIG. 17, the frame 101 further includes a first side plate 130.

[0109] In some embodiments, as shown in FIG. 14, FIG. 16, and FIG. 17, the frame 101 further includes a second side plate 140. The first side plate 130 and the second side plate 140 are respectively connected to two sides of the back plate 190 (i.e., the two sides in the width direction of the hydraulic module 1). For example, the first side plate 130 may be connected to the left side of the back plate 190, and the second side plate 140 may be connected to the right side of the back plate 190. At least one of an upper side and a lower side of the first side plate 130 is bent in the direction close to the second side plate 140 to form a third bent portion 132, and at least one of an upper side and a lower side of the second side plate 140 is bent in the direction close to the first side plate 130 to form a fourth bent portion 142.

[0110] A first part of the plurality of first plug-in portions 170 and a first part of the plurality of first screw-in portions 180 are arranged on the third bent portion 132, and a second part of the plurality of first plug-in portions 170 and a second part of the plurality of first screw-in portions 180 are arranged on the fourth bent portion 142.

[0111] For example, the upper side and the lower side of the first side plate 130 are both bent in the direction close to the second side plate 140 to form two third bent portions 132. The upper side and the lower side of the second side plate 140 are both bent in the direction close to the first side plate 130 to form two fourth bent portions 142.

[0112] In this way, along the width direction of the hydraulic module 1, one end of the top plate 160 is fixedly connected to the third bent portion 132 located on the upper side of the first side plate 130, the other end of the top plate 160 is fixedly connected to the fourth bent portion 142 located on the upper side of the second side plate 140, one end of the bottom plate 150 is fixedly connected to the third bent portion 132 located on the lower side of the first side plate 130, and the other end of the bottom plate 150 is fixedly connected to the fourth bent portion 142 located on the lower side of the second side plate 140, so that the top plate 160 and the bottom plate 150 can respectively seal the upper side and the lower side of the frame 101.

[0113] Moreover, the arrangement of the third bent portion 132 and the fourth bent portion 142 facilitates the construction of the first plug-in portion 170 and the first screw-in portion 180, and can increase a contact area between the frame 101 and the top plate 160 and a contact area between the frame 101 and the bottom plate 150, thereby helping to improve reliability of the connection between the frame 101 and the top plate 160 and the connection between the frame 101 and the bottom plate 150.

[0114] In some embodiments, as shown in FIG. 14, the back plate 190, the first side plate 130, and the second side plate 140 are constructed as an integral part, which can reduce a number of parts of the housing 100 and facilitate the assembly of the housing 100, and also helps to improve structural strength of the frame 101 and improve reliability of the connection among the back plate 190, the first side plate 130, and the second side plate 140.

[0115] In some embodiments, as shown in FIG. 7 and FIG. 16, the first plug-in portion 170 is configured as a plug-in hole, and the second plug-in portion 152 is configured as a plug-in block. The plurality of first plug-in portions 170 are correspondingly engaged with the plurality of second plug-in portions 152 to connect the frame 101 to the bottom plate 150 and to connect the frame 101 to the top plate 160.

[0116] The first screw-in portion 180 and the second screw-in portion 153 are configured as bolt holes. In this way, a plurality of bolt fasteners correspondingly pass through the plurality of first screw-in portions 180 and the plurality of second screw-in portions 153, thereby achieving a fixed connection between the frame 101 and the bottom plate 150 and a fixed connection between the frame 101 and the top plate 160.

[0117] Therefore, when the housing 100 is assembled, the plug-in block may be first inserted into the plug-in hole to pre-position the assembly of the frame 101, the top plate 160, and the bottom plate 150, thereby simplifying assembly steps of the housing 100. Then, the bolt fastener passes through the first screw-in portion 180 and the second screw-in portion 153 to fixedly connect the frame 101 and the top plate 160 as well as the frame 101 and the bottom plate 150, thereby ensuring strength of the connection between the frame 101 and the top plate 160 and between the frame 101 and the bottom plate 150, which helps to improve reliability of the housing 100.

[0118] It is to be noted that the manner of fixedly connecting the first panel 300 to the housing 100 and the related structure have been described above. Details are not described herein again.

[0119] In some embodiments, as shown in FIG. 18, the back plate 190 includes a back plate body 1900 and at least one mounting hole 191. The at least one mounting hole 191 passes through the back plate body 1900 along a thickness direction of the back plate body 1900. The mounting hole 191 is configured to fit a mounting plate pre-fixed to the wall. That is, when the hydraulic module 1 is fixed to the wall, the back plate 190 may be hung on the mounting plate through the mounting hole 191, thereby preliminarily fixing the hydraulic module 1.

[0120] In some embodiments, as shown in FIG. 16 to FIG. 18, the back plate 190 further includes a flange portion 192, and the flange portion 192 is arranged around the mounting hole 191. The flange portion 192 can enhance structural strength around the mounting hole 191, thereby improving reliability of the connection between the back plate 190 and the mounting plate and preventing deformation of the back plate 190.

[0121] In some embodiments, the flange portion 192 is arranged on the side of the back panel body 1900 facing the accommodating cavity 110, which can prevent interference of the flange portion 192 with the wall, thereby facilitating the mounting.

[0122] In some embodiments, as shown in FIG. 18, the back plate 190 further includes a protruding portion 193, and the protruding portion 193 is arranged on the back plate body 1900 and protrudes towards the accommodating cavity 110, to prevent interference of the protruding portion 193 with the wall. The protruding portion 193 is located on one side of the mounting hole 191, and is configured to improve structural strength of the back plate 190.

[0123] For example, the protruding portion 193 is located on an upper side of the mounting hole 191, and extends along the width direction of the hydraulic module 1. The protruding portion 193 is arranged close to the mounting hole 191, and is spaced apart from the mounting hole 191. In this way, the protruding portion 193 can improve the structural strength of the back plate 190, thereby improving stability of the connection between the hydraulic module 1 and the wall.

[0124] In some embodiments, the back plate 190 includes a plurality of protruding portions 193, the plurality of protruding portions 193 are spaced apart on the side of the back plate body 1900 facing the accommodating cavity 110, and extension directions of the plurality of protruding portions 193 may be the same or different, which can improve stability of the connection between the back plate 190 and the wall and can also improve stability of the connection between the components in the housing 100 (such as the heat exchanger 210, the water pump 200, and the expander 240) and the back plate 190.

[0125] In some embodiments, as shown in FIG. 18, the back plate 190 includes a plurality of assembly protrusions 197, and the plurality of assembly protrusions 197 are arranged on the back plate body 1900 and are located on the side of the back plate body 1900 facing away from the accommodating cavity 110. The plurality of assembly protrusions 197 are configured to abut against the wall to prevent direct contact of the back plate body 1900 with the wall, thereby helping to improve heat dissipation efficiency of the hydraulic module. In addition, when the temperature inside the hydraulic module 1 is low, liquid droplets may precipitate on the back plate body 1900. Therefore, through the abutment of the plurality of assembly protrusions 197 against the wall, damage to the wall caused by dripping of the liquid droplets onto the wall can be prevented.

[0126] For example, the plurality of assembly protrusions 197 include four assembly protrusions 197, and the four assembly protrusions 197 are respectively arranged at edge positions of the back plate body 1900 and protrude towards the rear side. The frame 101 abuts against the wall through the four assembly protrusions 197.

[0127] In some embodiments, as shown in FIG. 2, the hydraulic module 1 further includes a drain pan 250, and the drain pan 250 is arranged in the accommodating cavity 110, and is located at the bottom of the accommodating cavity 110. The drain pan 250 is configured to receive liquid dripping from the heat exchanger 210 or other components.

[0128] In some embodiments, as shown in FIG. 18, the back plate 190 further includes a first mounting protrusion 194. The first mounting protrusion 194 is arranged on the side of the back plate body 1900 facing the accommodating cavity 110, and protrudes towards the accommodating cavity 110. The first mounting protrusion 194 is arranged close to the bottom plate 150, and extends along the width direction of the hydraulic module 1. The drain pan 250 is fixedly connected to the first mounting protrusion 194. This can improve structural strength of the back plate 190 can be improved, and help to improve reliability of the connection between the back plate 190 and the drain pan 250.

[0129] In some embodiments, as shown in FIG. 18, the back plate 190 further includes a plurality of second mounting protrusions 195, and the plurality of second mounting protrusions 195 are arranged on the side of the back plate body 1900 facing the accommodating cavity 110, and protrude towards the accommodating cavity 110. The second mounting protrusion 195 is arranged close to the first side plate 130, and is located above the first mounting protrusion 194. The expander 240 is fixedly connected to the plurality of second mounting protrusions 195. This can improve structural strength of the back plate 190, and help to improve reliability of the connection between the back plate 190 and the expander 240.

[0130] It may be understood that the expander 240 has a large volume. Therefore, by arranging the plurality of second mounting protrusions 195 and arranging the plurality of second mounting protrusions 195 respectively at two ends of the expander 240 in a length direction or a width direction, stability of the connection between the expander 240 and the back plate 190 is improved. Compared with a single second mounting protrusion 195 with a larger size, a plurality of second mounting protrusions 195 with smaller sizes are easier to process and have higher structural strength.

[0131] In some embodiments, as shown in FIG. 18, the back plate 190 further includes a third mounting protrusion 196, and the third mounting protrusion 196 is arranged on the side of the back plate body 1900 facing the accommodating cavity 110, and protrudes towards the accommodating cavity 110. The third mounting protrusion 196 is arranged close to the second side plate 140, and is located above the first mounting protrusion 194. The heat exchanger 210 is fixedly connected to the third mounting protrusion 196. This can improve structural strength of the back plate 190, and help to improve reliability of the connection between the back plate 190 and the heat exchanger 210.

[0132] Therefore, through the arrangement of the first mounting protrusion 194, the second mounting protrusion 195, and the third mounting protrusion 196, the structural strength of the back plate 190 can be improved, and the structural strength at positions where the back plate 190 is connected to the drain pan 250, the expander 240, and the heat exchanger 210 can be improved, thereby improving reliability of the connection between the back plate 190 and the drain pan 250 and between the expander 240 and the heat exchanger 210.

[0133] In some embodiments, the hydraulic module 1 further includes a mounting bracket assembly 500. The mounting bracket assembly 500 is arranged in the accommodating cavity 110 and is close to the side of the hydraulic module 1 in the width direction. The heater 230 is arranged on the mounting bracket assembly 500. For example, the mounting bracket assembly 500 is located on the side of the heat exchanger 210 close to the first side plate 130. For example, the mounting bracket assembly 500 is arranged on the first side plate 130, and corresponds to the position of the heat exchanger 210. That is, the heater 230 and the heat exchanger 210 are arranged along the width direction of the hydraulic module 1, thereby preventing interference between the heater 230 and the heat exchanger 210 and facilitating the internal layout of the hydraulic module.

[0134] In this way, the heater 230 is connected to the housing 100 through the mounting bracket assembly 500, which helps to improve stability of the connection between the heater 230 and the housing 100.

[0135] In some embodiments, the position of the mounting bracket assembly 500 is adjustable. In this way, by adjusting the position of the mounting bracket assembly 500 relative to the first side plate 130 in the front-rear direction, the position of the heater 230 relative to the first side plate 130 can be adjusted, so that the heater 230 can be spaced apart from the back plate 190.

[0136] In some embodiments, the heater 230 and other components in the hydraulic module 1 (such as the expander 240 and the pipelines) may be arranged in the front-rear direction. For example, the other components may be located between the heater 230 and the back plate 190. It may be understood that, since the mounting bracket assembly 500 is arranged on the side plate of the housing 100, the mounting bracket assembly 500 is not easy to interfere with other components in the thickness direction of the hydraulic module 1, so that the heater 230 and part of the hydraulic module 1 can be arranged in the front-rear direction, and the other part of the hydraulic module 1 can be arranged in the left-right direction, which helps to reduce the size of the housing 100 and reduce a processing cost and a material cost of the housing 100.

[0137] In some embodiments, as shown in FIG. 2, the heat exchanger 210 is arranged on the back plate 190, and is close to the second side plate 193. The mounting bracket assembly 500 may be mounted on the first side plate 130 to connect and fix the heater 230 to the first side plate 130. In this way, the heater 230 may be spaced apart from the back plate 190, thereby facilitating the arrangement of the heater 230 and the components connected to the back plate 190 in the front-rear direction.

[0138] It is to be noted that, in some embodiments, the mounting bracket assembly 500 may alternatively be arranged on the second side plate 193. That is, the heat exchanger 210 is arranged adjacent to the first side plate 130, and the heater 230 is arranged adjacent to the second side plate 193.

[0139] In some embodiments, as shown in FIG. 20 to FIG. 22, the mounting bracket assembly 500 includes a first bracket 510 and a second bracket 520. The first bracket 510 is connected to the first side plate 130, the second bracket 520 is detachably mounted on the first bracket 510, and the heater 230 is arranged on the second bracket 520.

[0140] That is, the mounting bracket assembly 500 is a split part. In this way, when the heater 230 is mounted in the housing 100, the first bracket 510 may be connected to the housing 100 first, the second bracket 520 may be fixedly connected to the heater 230, and then the second bracket 520 may be mounted on the first bracket 510, thereby realizing the connection and fixation between the heater 230 and the housing 100, which helps to improve assembly efficiency of the heater.

[0141] In some embodiments, the first bracket 510 is welded and fixed to the first side plate 130, and the second bracket 520 is welded and fixed to an outer peripheral surface of the heater 230, thereby improving strength of the connection between the first bracket 510 and the first side plate 130 and strength of the connection between the second bracket 520 and the heater 230, and improving stability and reliability of the connection between the heater 230 and the housing 100.

[0142] In some embodiments, as shown in FIG. 22 and FIG. 23, the first bracket 510 includes a first bracket body 5100, and the first bracket body 5100 protrudes towards the back plate 190 to form a third positioning block 513. The back plate 190 includes a positioning hole corresponding to the position of the third positioning block 513, and the third positioning block 513 is arranged in the positioning hole to limit the first bracket 510 in the left-right direction and the up-down direction, thereby pre-positioning the first bracket 510 and the housing 100 and facilitating assembly connection between the first bracket 510 and the housing 100.

[0143] In some embodiments, as shown in FIG. 22 to FIG. 24, the first bracket 510 further includes a third plug-in portion 511 and a first fixing portion 512, and the third plug-in portion 511 and the first fixing portion 512 are spaced apart on the first bracket body 5100.

[0144] The second bracket 520 includes a fourth plug-in portion 521 and a second fixing portion 522, the third plug-in portion 511 is plugged into and fits the fourth plug-in portion 521, and the first fixing portion 512 is fixedly connected to the second fixing portion 522.

[0145] In this way, the first bracket 510 and the second bracket 520 can fit each other by plug-in through the third plug-in portion 511 and the fourth plug-in portion 521, and can also be fixedly connected through the first fixing portion 512 and the second fixing portion 522, which helps to improve assembly efficiency of the first bracket 510 and the second bracket 520, and at the same time can ensure reliability of the connection between the first bracket 510 and the second bracket 520, thereby improving stability of the connection between the heater 230 and the housing 100.

[0146] In some embodiments, as shown in FIG. 22 to FIG. 24, one of the third plug-in portion 511 and the fourth plug-in portion 521 is a socket, and the other is a plug. The plug is plugged into the socket. The first fixing portion 512 and the second fixing portion 522 are both mounting holes and are fixedly connected by a fastener. In this way, a number of screw connections between the first bracket 510 and the second bracket 520 can be reduced, which helps to improve assembly efficiency of the first bracket 510 and the second bracket 520.

[0147] For example, the third plug-in portion 511 is a plug and is arranged close to one side of the first bracket 510 in a length direction, and the fourth plug-in portion 521 is a socket. The first fixing portion 512 is arranged close to the other side of the first bracket 510 in the length direction. In this way, one side of the first bracket 510 fits the second bracket 520 by plug-in, and the other side of the first bracket 510 is connected to the second bracket 520 by the fastener, which helps to improve stability of the connection between the first bracket 510 and the second bracket 520.

[0148] For example, the third plug-in portion 511 protrudes towards the second side plate 140, and an upper side and a front side of the third plug-in portion 511 are open. The fourth plug-in portion 521 may be plugged into the fourth plug-in portion 521 from top to bottom or from front to back, so that side walls of the third plug-in portion 511 can be stopped at the side of the fourth plug-in portion 521 facing the back plate 190, a lower side of the fourth plug-in portion 521, and the side of the fourth plug-in portion 521 facing away from the first bracket body 5100, thereby supporting and fixing the second bracket 520 and limiting the second bracket 520 in a thickness direction of the first bracket 510.

[0149] In some embodiments, as shown in FIG. 22 and FIG. 24, the second bracket 520 includes a vertical portion 523 and a horizontal portion 524. The vertical portion 523 fits the first bracket body 5100, and extends along the height direction of the hydraulic module 1. The horizontal portion 524 is arranged at an upper end of the vertical portion 523, and extends towards the second side plate 140. The heater 230 is arranged on the horizontal portion 524. The fourth plug-in portion 521 and the second fixing portion 522 are arranged on the vertical portion 523.

[0150] For example, the side of the horizontal portion 524 facing the second side plate 140 is welded and fixed to the heater 230. The end of the horizontal portion 524 facing the heater 230 may be constructed as an arc that matches the outer peripheral surface of the heater 230, thereby increasing a contact area between the horizontal portion 524 and the heater 230, which helps to improve strength of the connection between the second bracket 520 and the heater 230. In addition, the vertical portion 523 fits the first bracket body 5100, which can increase a contact area between the vertical portion 523 and the first bracket 510, thereby helping to improve stability of the connection between the first bracket 510 and the second bracket 520.

[0151] In some embodiments, as shown in FIG. 2 and FIG. 4, the expander 240 is located at a rear side of the heater 230 and is fixedly connected to the housing 100, and the electric control box 220 is located at a front side of the heater 230 and is fixedly connected to the housing 100.

[0152] That is, the expander 240, the heater 230, and the electric control box 220 may be arranged along the front-rear direction of the housing 100, which facilitates the layout and mounting of the expander 240, the heater 230, and the electric control box 220 and can effectively reduce the size of the housing 100.

[0153] In some embodiments, as shown in FIG. 22 and FIG. 23, the first bracket 510 further includes an avoidance groove 514. The avoidance groove 514 is arranged on the first bracket body 5100 and corresponds to the position of the expander 240. The avoidance groove 514 is recessed in the direction away from the expander 240 to avoid the expander 240, thereby preventing positional interference between the first bracket 510 and the expander 240.

[0154] In some embodiments, the first bracket 510 is located on a front side of the expander 240, that is, the first bracket 510 is connected to the first side plate 130 and is spaced apart from the back plate 190 by a predetermined distance. In this way, a dimension of the first bracket 510 in the front-rear direction can be shortened, which helps to reduce a processing cost of the first bracket 510. In addition, the first bracket 510 may not extend between the expander 240 and the first side plate 130, so there is no need to arrange the avoidance groove 514 in the first bracket 510 to avoid the expander 240, which helps to simplify the structure of the first bracket 510 and facilitates the processing.

[0155] In some embodiments, as shown in FIG. 19, the hydraulic module 1 includes a plurality of mounting bracket assemblies 500, and the plurality of mounting bracket assemblies 500 are spaced apart on the first side plate 130 along the height direction of the hydraulic module. For example, the plurality of mounting bracket assemblies 500 may be spaced apart along an axial direction of the heater 230, and the plurality of mounting bracket assemblies 500 respectively fix a plurality of axial parts of the heater 230 and the first side plate 130, which helps to improve strength of the connection between the heater 230 and the first side plate 130.

[0156] Some embodiments of the present disclosure further provide an air conditioner 1000. As shown in FIG. 25, the air conditioner 1000 includes the hydraulic module 1 in any one of the foregoing embodiments and achieves the same technical effect as the hydraulic module 1, which is not described in detail in the present disclosure.

[0157] The air conditioner 1000 performs a refrigeration cycle of the air conditioner 1000 by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplying a refrigerant to exchange heat with the conditioned air.

[0158] The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges a compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to a surrounding environment through a condensation process.

[0159] The expansion valve expands a high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by utilizing latent heat of evaporation of the refrigerant to exchange heat with a to-be-cooled material. In the entire cycle, the air conditioner 1000 may regulate a temperature and humidity of an indoor space.

[0160] Those skilled in the art will understand that the scope of disclosure in the present invention is not limited to the foregoing specific embodiments and may modify and substitute some elements of the embodiments without departing from the spirits of the present disclosure. The scope of the present disclosure is limited by the appended claims.
