DETAILED DESCRIPTION

[0063] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0064] The hydraulic module is used to exchange heat between the refrigerant in the refrigerant flow channel and the water in the water delivery channel to heat the water, or to cool the water, thereby outputting water of a set temperature and delivering it to water storage devices such as water tanks, or to heat release devices such as floor heating pipes and radiators.

[0065] The inventors have discovered that the layout of the components of the hydraulic module, such as the heat exchange device, small water tank heater, water pump, expansion tank, temperature controller, and electronic control box, in the box is not designed properly, which easily leads to moisture remaining in the internal space of these devices, and the residual moisture easily causes corrosion to the internal structure of the components. For example, when the hydraulic module is inspected, the moisture inside the hydraulic module is discharged. If there is still moisture remaining, when the hydraulic module is put into use in the user's home, it will take a long time, and the residual moisture is likely to cause corrosion to the internal structure of the components. Therefore, it is necessary to set the layout of the components inside the hydraulic module so that the water in the internal space of the hydraulic module components can be more fully discharged. Based on this, the embodiment of the present application provides a hydraulic module and a heat pump system.

[0066] The hydraulic module provided in the embodiment of the present application can be used in air energy water heaters, and can also be used in home heating equipment such as floor heating and radiators, which will not be specifically limited here. Figures 1 to 3 FIG. 1 is a schematic diagram of the structure of a hydraulic module 10 provided in an embodiment of the present application.

[0067] The hydraulic module 10 provided in the embodiment of the present application includes a plurality of functional components, for example, the functional components include an expansion tank 200, a heat exchange device 300, a water tank 400, a water pump 500, and the like.

[0068] The heat exchange device 300 has a water channel and a refrigerant channel inside, and fluids of different temperatures flow through the water channel and the refrigerant channel respectively. The fluid in the water channel exchanges heat with the fluid in the refrigerant channel to adjust the temperature of the fluid in the water channel. The heat exchange device 300 includes a temperature detection component extending into the water channel, and the temperature detection component is used to obtain the temperature of the fluid in the water channel, so as to adjust the temperature of the fluid in the refrigerant channel according to the temperature of the fluid in the water channel, and then adjust the temperature of the fluid output from the water channel to a preset temperature range.

[0069] A first water inlet 310a is formed at one end of the water delivery channel, and a first water outlet 320a is formed at the other end. The first water inlet 310a is used to connect to an external water source. The water flow delivered by the external water source enters the water delivery channel from the first water inlet 310a and is output from the first water outlet 320a. The flow direction of the fluid in the water delivery channel is opposite to the flow direction of the fluid in the refrigerant channel, so as to improve the heat exchange efficiency between the fluid in the water delivery channel and the fluid in the refrigerant channel. The temperature detection component is used to detect the temperature of the water flow at and near the first water inlet 310a and the first water outlet 320a, so as to obtain the temperature state of the water flow in the water delivery channel. The heat exchange device 300 includes a plate heat exchange device 300, a sleeve heat exchange device 300, and the like.

[0070] The water tank 400 has a water storage cavity, and the water tank 400 also has a second water inlet 410a and a second water outlet 420a connected to the water storage cavity. Water flows into the water tank 400 from the second water inlet 410a and flows out of the water storage cavity from the second water outlet 420a, wherein part of the water entering the water tank 400 is buffered in the water storage cavity. The water tank 400 has a heater, and the heater is used to heat the water stored in the water storage cavity to adjust the temperature of the water flow output from the second water outlet 420a of the water tank 400.

[0071] The water pump 500 has a water intake end 510 and a water delivery end 520. The water intake end 510 of the water pump 500 is used to communicate with at least one of the water tank 400 or the heat exchange device 300, and the water delivery end 520 of the water pump 500 is used to communicate with the outside. Water flows into the water pump 500 from the water intake end 510 and is output to the external structure from the water delivery end 520. The water pump 500 is used to provide water delivery power so that the water in the hydraulic module 10 can flow in the internal space of the water tank 400 and the heat exchange device 300.

[0072] The expansion tank 200 has an expansion port 210 for communicating with at least one of the water tank 400 or the heat exchange device 300. The expansion tank 200 is used to balance the pressure change of water in the system due to temperature change. When the water temperature rises, the volume will expand, thereby increasing the pressure in the water pipe. The setting of the expansion tank 200 can make the expanded water in the system squeeze into the expansion tank 200, thereby achieving pressure balance of the water system within a certain range.

[0073] The first water outlet 320a is connected to the second water inlet 410a, and the second water outlet 420a is connected to the water drawing end 510 of the water pump 500. When the water pump 500 runs, it drives the water flow from the first water inlet 310a into the water delivery channel, flows from the first water outlet 320a to the second water inlet 410a and flows into the water storage chamber. The water in the water storage chamber is pumped from the second water outlet 420a to the water drawing end 510 of the water pump 500, and the water in the water pump 500 is then supplied to the external structure from the water delivery end 520. For example, the water delivery end 520 is connected to the floor heating pipe of the floor heating.

[0074] like Figure 2 As shown, in the gravity direction G, the water pump 500 is located below the water tank 400, the expansion tank 200 is located above the heat exchange device 300, the first water inlet 310a is lower than the first water outlet 320a, the first water outlet 320a is connected to the second water inlet 410a, and the first water outlet 320a is lower than the second water inlet 410a, or, the first water outlet 320a is flush with the second water inlet 410a, the second water inlet 410a is lower than the second water outlet 420a, and the second water outlet 420a is connected to the water intake end 510 of the water pump 500. In this way, when it is necessary to discharge the water inside the hydraulic module 10, under the action of gravity, the water in the water storage chamber of the water tank 400 can flow out through the second water inlet 410a, the first water outlet 320a, the water delivery channel and the first water inlet 310a in sequence, and the second water outlet 420a connected to the water pump 500 is also located above the water pump 500 in the gravity direction G, and the water flow inside the structural member connecting the second water outlet 420a and the water pump 500 water intake end 510 is also convenient to be discharged more fully under the action of gravity. In addition, the water tank 400 adopts a water supply method of bottom-in and top-out. When the water in the water storage chamber is heated, water is stored in the lower area of ​​the water storage chamber, which can reduce the risk of drying up and improve the safety of use.

[0075] The expansion port 210 of the expansion tank 200 is connected to the first water inlet 310a, so that the expansion tank 200 can also be connected to the water delivery channel of the heat exchange device 300 and the water storage chamber of the water tank 400, thereby balancing the pressure in the water delivery channel of the heat exchange device 300 and the water storage chamber of the water tank 400. In the gravity direction G, the first water inlet 310a is located in the area below the hydraulic module 10. The area below the hydraulic module 10 has a large space, which is convenient for arranging structural parts for detecting the pressure in the water delivery channel of the heat exchange device 300 and adjusting the pressure in the water delivery channel, so that the overall layout of the hydraulic module 10 is compact and easy to repair and install.

[0076] In the horizontal direction, the first water inlet 310a and the first water outlet 320a are both opened toward the side where the water tank 400 is located, and the second water inlet 410a and the second water outlet 420a are both opened toward the side where the heat exchange device 300 is located, so as to facilitate the connection between the first water outlet 320a and the second water inlet 410a, and to reduce the number of reversals of the structural parts connecting the first water outlet 320a and the second water inlet 410a. In addition, such an arrangement can also enable the structural parts connected to the first water inlet 310a, the first water outlet 320a, the second water inlet 410a and the second water outlet 420a to be more located between the water tank 400 and the heat exchange device 300, so that the overall layout of the hydraulic module 10 is compact, which is convenient for reducing the thickness of the hydraulic module 10.

[0077] The heat exchange device 300 includes a heat exchange box, and the heat exchange box has a water delivery channel and a refrigerant flow channel inside. The heat exchange device 300 also includes a first water inlet interface 310 and a first water outlet interface 320. The first water inlet interface 310 has a first water inlet 310a, and the first water outlet interface 320 has a first water outlet 320a. The first water inlet interface 310 and the first water outlet interface 320 are both convexly arranged on the outer surface of the heat exchange box, so that the structural member is connected to the first water inlet interface 310 and the first water outlet interface 320, so as to realize the communication between the first water inlet 310a and the first water outlet 320a and the corresponding structural member.

[0078] In the gravity direction G, the first water inlet 310a and the first water outlet 320a are arranged side by side along the first straight line A, so that the first water inlet 310a and the first water outlet 320a are arranged on the same straight line, which is convenient for arranging the positions of the structural parts connected to the first water inlet 310a and the first water outlet 320a, and at the same time prevents these structural parts from interfering with the structural parts connecting the refrigerant flow channel, so that the structural parts connected to the heat exchange device 300 are arranged in order, which is convenient for maintenance and installation.

[0079] The water tank 400 includes a water tank body, which has a water storage cavity. The water tank 400 also includes a second water inlet interface 410 connected to the second water inlet 410a, and a second water outlet interface 420 connected to the second water outlet 420a. The second water inlet interface 410 and the second water outlet interface 420 are both protruding from the outer surface of the water tank 400 so that structural parts can be set on the second water inlet interface 410 and the second water outlet interface 420 to achieve communication between the second water inlet 410a and the second water outlet 420a and the corresponding structural parts.

[0080] In the gravity direction G, the second water inlet 410a and the second water outlet 420a are arranged side by side along the second straight line B, so that the second water inlet 410a and the second water outlet 420a are arranged on the same straight line, so as to further improve the compactness of the water tank 400 and the structural parts connecting the head to the water tank 400, which helps to reduce the size of the hydraulic module 10.

[0081] The hydraulic module 10 also includes an integrated piping subsystem, which includes a plurality of connecting pipes. Two functional devices of the hydraulic module 10 are connected through at least one connecting pipe. For example, the first water outlet 320a of the heat exchange device 300 is connected to the second water inlet 410a of the water tank 400 through one connecting pipe or two connecting pipes; the second water outlet 420a of the water tank 400 is connected to the water intake end 510 of the water pump 500 through one connecting pipe or two connecting pipes. The present application does not limit the number of connecting pipes connecting two functional devices, which can be selected according to actual needs.

[0082] Optionally, one of the connecting pipes of the integrated piping subsystem is a transition pipe 610, which connects the first water outlet 320a and the second water inlet 410a. Specifically, one end of the transition pipe 610 is connected to the first water outlet interface 320 to communicate with the water supply channel, and one end of the transition pipe 610 is connected to the second water inlet interface 410 to communicate with the water storage chamber.

[0083] The transition pipe 610 is a transition straight pipe, the axial direction of which is perpendicular to the first straight line A and the second straight line B. The first water outlet 320a and the second water inlet 410a are connected through the transition straight pipe, which facilitates the smooth flow of water between the first water outlet 320a and the second water inlet 410a, so that the pipeline connecting the first water outlet 320a and the second water inlet 410a occupies less space.

[0084] Furthermore, the central axis of the transition straight pipe is located in the plane defined by the first straight line A and the second straight line B, that is, the central axes of the first water outlet 320a, the first water inlet 310a, the second water outlet 420a and the second water inlet 410a are coplanar, so that the water tank 400 and the heat exchange device 300 can be coplanar, which facilitates the compact structure of the hydraulic module 10 and also facilitates the smooth flow of water in the water tank 400, the heat exchange device 300 and the connecting pipeline.

[0085] At least one of the connecting pipes of the integrated pipe subsystem forms a water tank guide pipe 620, one end of which is connected to the second water outlet interface 420, and the other end of the water tank guide pipe 620 is connected to the water drawing end 510 of the water pump 500, and the second water outlet 420a and the water drawing end 510 of the water pump 500 are connected through the water tank guide pipe 620. In the gravity direction G, the water pump 500 is located below the water tank 400, so that the second water inlet 410a and the second water outlet 420a are both higher than the water pump 500, therefore, the length of the water tank guide pipe 620 connecting the second water outlet 420a and the water drawing end 510 of the water pump 500 also needs to be designed to be longer, and the water tank guide pipe 620 can be arranged to be spliced ​​by two or three sections of connecting pipes for easy assembly.

[0086] When the water tank flow guide pipe 620 is connected to the second water outlet 420a and the water intake end 510 of the water pump 500, the water tank flow guide pipe 620 is optionally set to extend from the second water outlet 420a to pass through the outside of the transition pipe 610 and then extend to connect with the water intake end 510 of the water pump 500, so that the water tank flow guide pipe 620 can also be relatively concentrated between the water tank 400 and the heat exchange device 300, making full use of the installation space. The water tank flow guide pipe 620 designed in this way has a multi-section bending structure. Optionally, the water tank flow guide pipe 620 includes a first straight pipe 621, a second straight pipe 622 and a third straight pipe 623 connected in sequence. The first straight pipe 621 and the third straight pipe 623 are respectively arranged at an angle with the second straight pipe 622.

[0087] Specifically, Figure 3 As shown, the axial direction of the first straight pipe 621 is perpendicular to the second straight line B, and the first straight pipe 621 is connected to the second water outlet 420a. For example, the second water outlet interface 420 is convexly disposed on the outer surface of the water tank body, the axial direction of the second water outlet interface 420 is parallel to the axial direction of the transition straight pipe, the first straight pipe 621 is connected to the second water outlet interface 420, and the axial direction of the first straight pipe 621 is perpendicular to the axial direction of the second water outlet interface 420. The second straight pipe 622 is connected to the first straight pipe 621, and the second straight pipe 622 extends from the first straight pipe 621 along a direction parallel to the second straight line B to pass through the outside of the transition pipe 610 and extend to connect with the third straight pipe 623. For example, the axial directions of the first straight pipe 621, the second straight pipe 622 and the second water outlet interface 420 are angled with each other. The third straight pipe 623 extends from the second straight pipe 622 along a direction angled with the second straight line B to connect with the water intake end 510 of the water pump 500. In this way, the water tank guide pipe 620 is formed into a two-section bending structure, and the bending angle of the water tank guide pipe 620 at the bending part can be made larger, so as to facilitate the flow of water and drain water smoothly.

[0088] The first straight pipe 621, the second straight pipe 622 and the third straight pipe 623 of the water tank flow guide pipe 620 can each be formed by a section of connecting pipe; or, the water tank flow guide pipe 620 is formed by splicing two sections of connecting pipes, for example, a part of one connecting pipe forms the first straight pipe 621, and the other part is connected with a part of another connecting pipe to form the second straight pipe 622, and the remaining part of the other connecting pipe forms the third straight pipe 623.

The expansion guide pipe 630 is provided to include two sections of pipe bodies, so that the expansion guide pipe 630 is conveniently processed and formed in one piece. Optionally, the first pipe section 631 and the second pipe section 632 are integrally injection molded.

[0093] Both the first pipe segment 631 and the second pipe segment 632 are straight pipes, and the axial direction of the second pipe segment 632 forms an angle with the axial direction of the first pipe segment 631.

[0098] The hydraulic module 10 further includes a pressure relief valve 703, which is disposed in the expansion guide tube 630.

[0115] like Figure 5 As shown, the outer peripheral wall of the plug-in portion 22 is provided with a limiting groove 20a, so that when the plug-in portion 22 is plugged into the plug-in hole 21a, the limiting groove 20a corresponds to the limiting hole 21b, so that the limiting member 23 can smoothly pass through the limiting hole 21b and be plugged into the limiting groove 20a.

[0116] Optionally, the limiting groove 20a is an annular limiting groove 20a arranged around the outer periphery of the plug-in portion 22, which facilitates the limiting member 23 to be inserted into the limiting groove 20a at multiple angles, and facilitates the multi-angle splicing of the plug-in portion 22 and the sleeve portion 21, making the assembly more flexible.

Prevent the sleeve portion 21 and the sleeve portion 21 from rotating relative to each other around the axial direction of the plug hole 21a.

[0118] The limiting member 23 is arranged around the outer circumference of the sleeve portion 21. During assembly, the two ends of the limiting member 23 correspond to the two limiting holes 21b one by one and are inserted into the two limiting holes 21b, so that it is easy to insert into place in one step and to facilitate assembly and disassembly.

Among them, the distance from the annular sealing groove 20c to the first end wall surface 20b is smaller than the distance from the limiting hole 21b to the first end wall surface 20b, so that more parts of the hard support portion 221 can extend into the plug-in hole 21a, thereby improving the stability of the plug-in portion 22 inserted into the sleeve portion 21 and maintaining a good sealing effect of the sealing ring.

[0136] In some other embodiments, the sixth plate body 36 may also be provided to include only the first insulation part, the third insulation part and the fourth insulation part, extending from the second plate body 32 to cover the side of the heat exchange device 300 away from the fourth plate body 34, and the heat exchange space 30f is defined by the second plate body 32, the first insulation part, the third insulation part, the fourth insulation part and the fifth plate body 35.

[0137] Among them, each plate body of the thermal insulation support member (including the first plate body 31, the second plate body 32, the third plate body 33, the fourth plate body 34, the fifth plate body 35 and the sixth plate body 36) abuts against the surface of the corresponding functional device to define the position of each functional device and provide support for each functional device. For example, each plate body of the thermal insulation support member can be connected with an adjacent plate body to fix the position of two adjacent plate bodies; or, each plate body of the thermal insulation support member abuts against the inner wall surface of the box body 100 to fix the position of two adjacent plate bodies; or, each plate body of the thermal insulation support member adopts a combined installation method of connecting adjacent plate bodies and abutting the plate body with the inner wall surface of the box body 100 to fix the position of two adjacent plate bodies.

[0138] The hydraulic module 10 further includes an electric control box 800, which has a conductive element. In the gravity direction G, the distance from the electric control box 800 to the top wall 110 is smaller than the distance from the electric control box 800 to the bottom wall 120. The electric control box 800 is arranged in the upper area of ​​the accommodating cavity 100a of the box body 100 to prevent the conductive element from being short-circuited in the bottom wet area of ​​the accommodating cavity 100a. The electric control box 800 is arranged outside the thermal insulation support member, and the electric control box 800 abuts against the thermal insulation support member, for example, the electric control box 800 abuts against the second plate body 32, or the electric control box 800 abuts against the second plate body 32 and the sixth plate body 36, so as to improve the installation stability of each plate body of the thermal insulation support member.

[0139] The front side wall can be opened or closed. Optionally, the electric control box 800 is arranged on the front side wall, and the electric control box 800 can move with the front side wall. After opening the front side wall, the second plate body 32, the fifth plate body 35 or other plates of the heat preservation support member can be disassembled to inspect and repair the components in the box body 100, which is convenient to operate.

[0140] The heat-insulating support member is a polypropylene foam board, which has good structural strength, can provide stable support for the functional device, and has good heat-insulating effect. Alternatively, in some other embodiments, the heat-insulating support member includes a hard support shell and a heat-insulating material layer filled in the inner space of the hard support shell.

[0141] The hydraulic module 10 further includes a water receiving tray 140, which is disposed in the accommodating cavity 100a and mounted on the bottom wall 120. Figure 8 As shown, the middle area of ​​the water receiving tray 140 has a plurality of docking openings 140 a , and each docking opening 140 a corresponds to one of the pipe installation openings of the bottom wall 120 .

[0142] The integrated piping subsystem includes a plurality of piping interfaces 640 for docking with an external system. For example, the piping interfaces 640 of the integrated piping subsystem include but are not limited to interfaces corresponding to the refrigerant input pipe 704, the refrigerant output pipe 705, the expansion guide pipe 630, the water delivery end 520 of the water pump 500 and other pipelines.

[0143] Each pipe interface 640 is passed through one of the docking openings 140a, and each pipe interface 640 is fixed to the water receiving tray 140. The liquid condensed on the outer surface of the device of the integrated pipe subsystem is retained at the pipe interface 640 under the action of gravity and flows along the surface of the pipe interface 640 into the water receiving tray 140. Among them, multiple docking openings 140a of the water receiving tray 140 are opened in the middle area of ​​the water receiving tray 140, and multiple pipe interfaces 640 of the integrated pipe subsystem are concentrated and installed in the middle area of ​​the water receiving tray 140 to prevent the pipe interfaces 640 from contacting the inner wall surface of the box body 100, causing the liquid condensed on the surface of the device of the integrated pipe subsystem to flow along the inner wall surface of the box body 100 to the bottom wall 120 and fail to be discharged from the bottom wall 120. The water receiving tray 140 can more comprehensively collect water droplets dripping from the surface of the functional device and the surface of the device of the integrated pipe subsystem, so that more water vapor can be discharged through the water receiving tray 140, thereby reducing the humidity of the internal space of the box body 100.

[0144] The water receiving tray 140 includes a water receiving main body 142 and a raised portion 141. There are multiple raised portions 141, and the raised portions 141 are protruded from the surface of the water receiving main body 142 away from the bottom wall 120. Each raised portion 141 has a docking opening 140a. When the pipe interface 640 is installed corresponding to the docking opening 140a, water can flow to the water receiving main body 142 through the surface of the pipe interface 640 and the surface of the raised portion 141 in sequence, preventing water from remaining at the docking opening 140a.

[0145] The pipe interface 640 is fixed to at least one of the protrusion 141 and the water receiving body 142. For example, the pipe interface 640 is fixed to the protrusion 141, so that the portion of the pipe interface 640 closer to the docking opening 140a is fixed, thereby improving the stability of the pipe interface 640 fixed to the water receiving tray 140 and improving the sealing performance of the connection between the pipe interface 640 and the water receiving tray 140.

[0146] The hydraulic module 10 also includes an interface sealing gasket, which is arranged between the pipeline interface 640 and the raised portion 141. The interface sealing gasket seals the gap between the pipeline interface 640 and the raised portion 141 to prevent water vapor from entering the docking opening 140a through the gap between the pipeline interface 640 and the raised portion 141.

[0147] The water receiving tray 140 has a water collecting groove 140c and a drain port 142a. The drain port 142a is provided at the bottom wall 120 of the water drawing groove. The water flowing into the water drawing groove is discharged to the external space from the drain port 142a. In the gravity direction G, the drain port 142a is lower than the docking opening 140a, further preventing the water flowing into the water collecting groove 140c from overflowing into the docking opening 140a. For example, the drain port 142a is provided at the surface of the water receiving body 142.

[0148] Among them, the pressure relief pipe 706 connected to the pressure relief valve 703 passes through the drain port 142a to communicate with the external atmosphere, and the opening through which the pressure relief pipe 706 passes is the same opening as the drain port 142a, which simplifies the structure of the water receiving tray 140, reduces the number of openings on the water receiving tray 140, and thereby reduces the occurrence of water falling from the opening of the water receiving tray 140 to the bottom wall 120 of the box body 100.

[0149] Optionally, the outer diameter of the pressure relief pipe 706 is smaller than the inner diameter of the drain port 142a, and the water in the water collection tank 140c can flow out from the outer surface of the pressure relief pipe 706 and the wall surface of the water receiving pan 140 defining the drain port 142a. In some other embodiments, the outer surface of the portion of the pressure relief pipe 706 that passes through the drain port 142a is provided with an opening or a groove, and the water in the water collection tank 140c can be discharged from the opening or the groove on the outer surface of the pressure relief pipe 706.

[0150] Optionally, the pipe interface 640 has a guide flange 641, the pipe interface 640 passes through one of the docking openings 140a, and the guide flange 641 covers the corresponding docking opening 140a and is connected to the surface of the water receiving tray 140. The docking opening 140a is closed by the guide flange 641, and the guide flange 641 can guide the water flow into the water collecting tank 140c of the water receiving tray 140.

[0151] The guide flange 641 extends away from the central axis of the docking opening 140a and is fixed to the water receiving tray 140. The guide flange 641 increases the contact area between the pipe interface 640 and the water receiving tray 140, thereby improving the installation stability of the pipe interface 640.

[0152] Optionally, the guide flange 641 covers the raised portion 141 and is fixed to the raised portion 141; or, the guide flange 641 covers the raised portion 141 and extends to connect to the water receiving body 142, so that the distance from the outer edge of the guide flange 641 to the docking opening 140a is larger, further reducing the probability of water flowing to the docking opening 140a. For example, the guide flange 641 is fixed to the raised portion 141 of the water receiving tray 140, and the guide flange 641 is fixed to the water receiving tray 140 by screws.

[0153] As shown in the figure, optionally, the pipeline interface 640 includes a first interface 6401 and a second interface 6402, the first interface 6401 is arranged in the accommodating cavity 100a, the second interface 6402 is arranged on the side of the bottom wall 120 away from the first interface 6401, and the second interface 6402 passes through the pipeline installation opening and the docking opening 140a in sequence and is inserted into the flow channel of the first interface 6401. The first interface 6401 abuts and is fixed to the water receiving tray 140, and the second interface 6402 abuts and is fixed to the bottom wall 120. Among them, the first interface 6401 has a guide flange 641, and the second interface 6402 has a mounting flange 642. The guide flange 641 and the mounting flange 642 can increase the contact area, thereby improving the installation stability of the pipeline interface 640 installed at the docking opening 140a.

[0154] The water collecting tray 140 includes a folded portion 143, which is connected to the outer periphery of the water collecting main body 142, and the folded portion 143 is in contact with the inner wall surface of the peripheral side wall 130. The folded portion 143, the water collecting main body 142 and the raised portion 141 define a water collecting trough 140c, and the water collecting trough 140c has a depth in the gravity direction G so that the water collecting trough 140c can buffer a certain volume of accumulated water to prevent the accumulated water in the water collecting trough 140c from overflowing the water collecting trough 140c.

[0155] The edge area of ​​the water receiving tray 140 contacts the inner wall surface of the peripheral side wall 130. Specifically, the folded portion 143 of the water receiving tray 140 contacts the inner wall surface of the peripheral side wall 130, so that the water receiving tray 140 corresponds to more functional components in the lower area of ​​the box body 100, thereby more comprehensively collecting water droplets dripping from the functional components.

[0156] The folded portion 143, the water receiving main body 142 and the raised portion 141 are integrally arranged, for example, the folded portion 143, the water receiving main body 142 and the raised portion 141 are integrally injection molded or integrally vacuum molded, the process is simple, and the overall thickness of the water receiving tray 140 is thin, and the water receiving tray 140 occupies a small space of the box body 100, which is convenient for the miniaturized design of the hydraulic module 10.

[0157] The embodiment of the present application also provides a heat pump system, including the hydraulic module 10 as described above. The water flow in the internal space of the functional components of the hydraulic module 10 can be discharged more fully, and the humidity in the box 100 of the hydraulic module 10 can be lower. The various components of the hydraulic module 10 of the embodiment of the present application can be in a relatively dry and good environment, so that the hydraulic module 10 has good stability in use, and thus the heat pump system installed with the hydraulic module 10 also has good stability in use.
