[0046] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0047] In the description of the present invention, it should be understood that descriptions involving orientation, such as the orientation or positional relationship indicated by up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0048] In the description of the present invention, "a plurality" refers to more than two. The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of the indicated technical features, or implicitly indicating the order of the indicated technical features.

[0049] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0050] Reference Figure 1 and Figure 2 As shown, a hydraulic module 1000 according to an embodiment of the present invention can be used in air-to-water heaters, as well as in household heating equipment such as floor heating and radiators, without further limitation herein. It should be noted that the hydraulic module 1000 is used to exchange heat between the refrigerant in the refrigerant pipe 600 and the water in the water pipe 500, thereby heating or cooling the water, thereby outputting water at a set temperature to a water storage device such as a water tank, or to a heat release device such as a floor heating pipe or radiator.

[0051] Reference Figure 1 and Figure 2 As shown, the hydraulic module 1000 of the embodiment of the present invention includes a housing 100. The interior of the housing 100 forms a receiving cavity (not shown in the figure). The hydraulic module 1000 of the embodiment of the present invention also includes components such as a heat exchanger 200, an expansion tank 300, and a water pump 400. The heat exchanger 200, the expansion tank 300, and the water pump 400 are arranged in the receiving cavity. The housing 100 includes a bottom plate 110 and a panel (not shown in the figure), as well as a side plate 120 arranged between the bottom plate 110 and the panel. The heat exchanger 200, the expansion tank 300, and the water pump 400 are all mounted on the bottom plate 110, thereby making the overall structure of the hydraulic module 1000 more stable. The heat exchanger 200 is installed in the middle space of the accommodating cavity, the expansion tank 300 is installed in the upper space of the accommodating cavity, and the water pump 400 is installed in the lower space of the accommodating cavity. Therefore, the expansion tank 300 and the water pump 400 are spaced apart above and below the heat exchanger 200, respectively. The heat exchanger 200 is a core component, and other components such as the expansion tank 300 and the water pump 400 are connected to the heat exchanger 200. In addition, the heat exchanger 200 is relatively heavy, so placing it in the middle space of the box body 100 is conducive to the installation and placement of other components and pipelines. The overall weight of the hydraulic module 1000 is also relatively more concentrated in the middle, which is conducive to the transportation and installation of the hydraulic module 1000. The hydraulic module 1000 of the embodiment of the present invention optimizes the position layout of the three components, making the layout of the various components of the hydraulic module 1000 more reasonable. When the hydraulic module 1000 needs to increase the heat exchange capacity, it can be increased by increasing the height direction between the bottom plate 110 and the panel (i.e. Figure 2 Increasing the size of the heat exchanger 200 (in the front-to-back direction) provides ample room for expansion, enabling it to be increased within the enclosure 100 while maintaining the same dimensions and component layout. This also allows for varying heat exchange capacities within the hydraulic modules 1000, enhancing the versatility of the enclosure 100. The expansion tank 300 is located externally to the heat exchanger 200, facilitating maintenance and improving efficiency. It also facilitates assembly.

[0052] Reference Figure 1 and Figure 3 As shown, the hydraulic module 1000 of this embodiment of the present invention further includes a water pipe 500 and a refrigerant pipe 600. Portions of the water pipe 500 and refrigerant pipe 600 are disposed within the accommodating cavity. One end of the water inlet section of the water pipe 500 is provided with a water inlet connector 510, located on the outer side of the lower end surface of the side panel 120. The other end is connected to the heat exchanger 200. The connecting pipe section 570 of the water pipe 500 is connected between the heat exchanger 200 and the water pump 400. The connecting pipe section 570 includes a first pipe 571, a second pipe 572, and a connecting pipe 573.

[0053] Reference Figure 3 and Figure 4 As shown, heat exchanger 200 is a double-tube heat exchanger with a hollow interior. A first tube 571 is vertically inserted through the hollow interior. The lower end of first tube 571 is connected to water pump 400, and the upper end of first tube 571 is provided with an exhaust valve 560. Exhaust valve 560 is used to exhaust gas from water pipe 500 to ensure normal water flow. A second tube 572 is arranged horizontally and connected to the end of first tube 571 near exhaust valve 560. Second tube 572 is provided with a water flow switch 550, which detects whether the water flow is normal. The water flow signal is fed back to the controller via a wire. A connecting tube 573 connects second tube 572 and the double-tube heat exchanger. Connecting tube 573 is U-shaped to facilitate connection to the double-tube heat exchanger. The above arrangement of connecting pipe 570 in this embodiment of the present invention can effectively reduce bends in the water pipe, reduce resistance in the water pipe, and reduce the impact noise of the water flow in the water pipe.

[0054] In the hydraulic module of this embodiment of the present invention, the outlet section of the water pipe 500 is connected to the water pump 400 at one end, and the other end extends to the outside of the lower end surface of the side panel 120 and is provided with a water outlet connector 520. The inlet section of the refrigerant pipe 600 is provided with a refrigerant gas connector 610 at one end and connected to the heat exchanger 200 at the other end. The liquid outlet section of the refrigerant pipe 600, after being throttled by the electronic expansion valve 700, extends to the outside of the lower end surface of the side panel 120 and is provided with a refrigerant liquid connector 620. The water inlet connector 510, water outlet connector 520, refrigerant liquid connector 620, and refrigerant gas connector 610 are spaced apart on the lower end surface of the side panel 120, thereby facilitating the connection of the hydraulic module 1000 to external piping.

[0055] The hydraulic module 1000 of the embodiment of the present invention optimizes the arrangement of the refrigerant pipe 600 and the water pipe 500 within the receiving chamber by positioning the water pump 400 near the lower end surface of the side panel 120, positioning the heat exchanger 200 above the water pump 400, and positioning the water inlet connector 510, the water outlet connector 520, the refrigerant liquid connector 620, and the refrigerant gas connector 610 below the water pump 400. This effectively reduces the length of the pipes, lowering manufacturing costs and reducing pipe bends. This reduces the system resistance of the hydraulic module 1000, lowers its energy consumption, and improves its energy efficiency. Furthermore, it reduces noise caused by water flow impact in curved pipe sections.

[0056] Reference Figure 1 and Figure 2As shown, the hydraulic module 1000 of this embodiment of the present invention has an electrical control box 800 mounted on its panel. The electrical control box 800 is located in the upper space of the accommodating chamber. The electrical control box 800, facing the outside of the hydraulic module 1000, is equipped with a display screen for displaying parameters such as water temperature, as well as a touch screen or buttons for controlling these parameters. The electrical control box 800 is positioned on the panel corresponding to the expansion tank 300, that is, spaced apart from the end of the expansion tank 300 away from the base plate 110. This allows for more efficient use of the accommodating chamber space, increases the size of the heat exchanger 200, and improves the heat exchange capacity of the hydraulic module 1000.

[0057] Reference Figure 3 and Figure 4 As shown, it can be understood that the heat exchanger 200 adopts a double-tube heat exchanger, and the pipes of the double-tube heat exchanger are spiral structures in the vertical direction. The double-tube heat exchanger includes an inner tube 210 and an outer tube 220. The outer tube 220 is sleeved on the outer circumference of the inner tube 210. The inner tube 210 is connected to the water pipe 500 and is used for water flow. The outer tube 220 is connected to the refrigerant pipe 600 and is used to flow refrigerant between the outer tube 220 and the inner tube 210. Heat is exchanged between the inner tube 210 and the outer tube 220 through heat transfer, thereby transferring heat from the refrigerant to the water, thereby heating the water and achieving the function of hot water production.

[0058] It can be understood that when the hydraulic module 1000 is used to make hot water, the hydraulic module 1000 of the embodiment of the present invention realizes the reverse flow of water and refrigerant in the shell and tube heat exchanger by connecting the inner tube 210 and the outer tube 220 at one end of the shell and tube heat exchanger to the inlet of the water pipe 500 and the outlet of the refrigerant pipe 600 respectively, and correspondingly, connecting the inner tube 210 and the outer tube 220 at the other end of the shell and tube heat exchanger to the outlet of the water pipe 500 and the inlet of the refrigerant pipe 600 respectively, thereby achieving a higher heat exchange efficiency.

[0059] Reference Figure 3 and Figure 4 As shown, it can be understood that the hydraulic module 1000 also includes a safety valve 530 and a water pressure gauge 540. The safety valve 530 and the water pressure gauge 540 are arranged in the water inlet pipe section of the water pipe 500. It can be understood that the safety valve 530 is used to automatically open to drain and relieve pressure when the water pressure exceeds the pressure set by the safety valve 530, thereby maintaining the water pressure and ensuring that the system is protected from damage; the water pressure gauge 540 is used to detect the water pressure value of the water pipe 500.

[0060] Reference Figure 4 and Figure 5As shown, it is understood that the hydraulic module 1000 further includes a first bracket 130, and the expansion tank 300 is mounted on the base plate 110 via the first bracket 130. It should be noted that the expansion tank 300 is used to balance the pressure changes of the water in the system caused by temperature changes. When the water temperature rises, the volume will expand, resulting in an increase in the pressure in the water pipe 500. The installation of the expansion tank 300 can squeeze the expanded water in the system into the expansion tank 300, thereby achieving pressure balance in the water system within a certain range.

[0061] Reference Figure 5 As shown, it can be understood that the first bracket 130 includes a first fixing seat 131 and a fixing card 132, and the end of the first fixing seat 131 facing the base plate 110 is fixedly connected to the base plate 110, and the end of the first fixing seat 131 away from the base plate 110 is detachably connected to the fixing card 132, and the first fixing seat 131 and the fixing card 132 are together arranged around at least part of the peripheral wall of the expansion tank 300, so as to be positioned and connected to the expansion tank 300, thereby realizing a stable connection between the first bracket 130 and the expansion tank 300, and the expansion tank 300 can be easily disassembled and repaired.

[0062] Reference Figure 6 and Figure 7 As shown, it can be understood that the first fixing seat 131 includes a first support plate 1311 and a first folding edge 1312. The first support plate 1311 is provided with a clearance opening 1313, which enables the outer surface of the expansion tank 300 to be embedded in the clearance opening 1313 when the expansion tank 300 is installed. The clearance opening 1313 is provided with a clamping hole 1314, which is positioned with a part of the boss 310 on the peripheral wall of the expansion tank 300 to achieve the positioning function of the expansion tank 300. The first folding edge 1312 is symmetrically provided with two and respectively connected to the first support plate 1311 along the first direction ( Figure 6 The ends of the fixing clip 132 are respectively connected to the two first folded edges 1312, thereby forming a space surrounding the peripheral wall of the expansion tank 300. Furthermore, during after-sales disassembly and assembly, because the hydraulic module 1000 is installed in a hanging manner, disassembly and assembly of the expansion tank 300 is more convenient.

[0063] The first fixing seat 131 further includes a mounting edge 1315, which is symmetrically provided with two mounting edges 1315 and the two mounting edges 1315 are respectively connected to the first support plate 1311 along the second direction ( Figure 6 At both ends (in the up-down direction in the second direction), the mounting edges 1315 are fixedly connected to the base plate 110, and the second direction is perpendicular to the first direction, thereby making the structure of the first fixing seat 131 more stable. It is understood that the mounting edges 1315 can be fixedly connected to the base plate 110 using fasteners such as rivets and screws, which are not specifically limited here.

[0064] Reference Figure 7As shown, the fixing clip 132 is provided with a first mounting plate 1321 at each end. The first mounting plate 1321 is fixedly connected to the first folded edge 1312 via fasteners such as screws. Furthermore, the first mounting plate 1321 is provided with a first positioning edge 1322. Correspondingly, the first folded edge 1312 is provided with a first positioning groove 1316. The first positioning groove 1316 engages with the first positioning edge 1322, thereby facilitating the positioning of the fixing clip 132 with the first fixing seat 131, facilitating the installation of fasteners, and improving the installation efficiency of the expansion tank 300.

[0065] Reference Figure 5 and Figure 7 As shown, it can be understood that the fixing clamp 132 includes at most five plates 1323 that are interconnected and angled with each other. The five plates 1323 contact the peripheral wall of the expansion tank 300, thereby applying pressure to the expansion tank 300 to secure the expansion tank 300. Of course, the fixing clamp 132 may also include three, four, or more interconnected plates 1323, which is not specifically limited here.

[0066] Reference Figure 5 As shown, it can be understood that the peripheral wall of the expansion tank 300 is provided with a boss 310, and each plate 1323 is correspondingly provided with a limiting hole 1324, which respectively cooperates with the boss 310 at the corresponding position. The fixing clip 132 is provided with a limiting hole 1324 that cooperates with the boss 310, which can enhance the positioning effect of the fixing clip 132 and the expansion tank 300, so that the expansion tank 300 and the fixing clip 132 can be better installed and fixed.

[0067] It is understandable that the first fixing seat 131 and the fixing clip 132 can be integrally formed by a sheet metal folding process, thereby improving the structural strength of the first bracket 130 and improving the installation stability of the expansion tank 300.

[0068] Reference Figure 8 As shown, it is understood that the hydraulic module 1000 also includes a buffer block 140 located below the first bracket 130. The buffer block 140 can be made of a material such as sponge. The buffer block 140 is mounted on the base plate 110 and supports the water pipe 500 at the lower end of the expansion tank 300, thereby reducing vibration at the connection between the expansion tank 300 and the water pipe 500, thereby ensuring the safety of the hydraulic module 1000 during production, handling, or transportation.

[0069] Reference Figure 3As shown, it can be understood that the expansion tank 300 is arranged in the upper space of the accommodating cavity and is located on the right side of the upper space. Therefore, space is reserved on the left side of the upper space for setting up an electric heating component (not shown in the figure). When the hydraulic module 1000 has higher functional requirements, the electric heating component can be installed on the left side of the upper space without changing the internal layout of the box body 100, so that the electric heating component and the expansion tank 300 are arranged at intervals and are both located above the heat exchanger 200, which can better maintain the consistency of the structural layout of the same series of products and improve the versatility of the box body 100.

[0070] Reference Figure 8 and Figure 9 As shown, it is understood that the hydraulic module 1000 also includes a second bracket 150. The second bracket 150 is mounted on the base plate 110 and is used to mount the water pump 400. The second bracket 150 and the water pump 400 can be directly connected or connected through a support member 160. The second bracket 150 includes a second support plate 151 and two second folded edges 152. The two second folded edges 152 are respectively connected to the two ends of the second support plate 151. The second folded edges 152 are used to separate the second support plate 151 from the base plate 110 by a certain distance. A second mounting plate 153 is provided at one end of the second folded edge 152 away from the second support plate 151. The second mounting plate 153 is fixed to the base plate 110 by fasteners such as screws, thereby achieving a stable connection between the second bracket 150 and the base plate 110.

[0071] Reference Figure 9 and Figure 10 As shown, it can be understood that the second folded edge 152 is provided with a second positioning edge 1521, and correspondingly, the base plate 110 is provided with a second positioning groove 111, and the second positioning groove 111 cooperates with the second positioning edge 1521, so as to facilitate the positioning of the second bracket 150 and the base plate 110 and facilitate the installation of fasteners.

[0072] It is understandable that the second bracket 150 can be integrally formed by a sheet metal folding process, thereby improving the structural strength of the second bracket 150 and improving the installation stability of the expansion tank 300.

[0073] Reference Figure 4 and Figure 8As shown, a water pump 400 according to an embodiment of the present invention is mounted on the second support plate 151 via a support member 160. The support member 160 is a structure with elastic deformation capability, such as a rubber member. The support member 160 can be injection molded using rubber or other cushioning materials to make the structure of the support member 160 more durable and reliable. A groove structure (not shown) can also be provided within the support member 160 to effectively reduce the weight of the support member 160 while increasing the elastic cushioning performance of the support member 160. It is understood that during the transportation or handling of the hydraulic module 1000, the water pump 400 may be subjected to external forces and collide.
