[0039] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0040] As described in the background, in related art, an expansion tank is installed inside a hydraulic module, and the expansion tank is fixed to the hydraulic module via a connecting flange at the bottom of the tank body. This connection method requires a large space at the bottom of the expansion tank, making it difficult to secure and remove the expansion tank, and thus making it difficult to maintain and repair the expansion tank.

[0041] Therefore, the embodiments of the present application propose a hydraulic module and a heat pump system to facilitate the convenience of fixing, connecting and disassembling the expansion tank, thereby improving the convenience of inspection and maintenance.

[0042] In the first aspect, the present application proposes a hydraulic module 10. Figures 1 to 4As shown, the hydraulic module 10 includes a housing 100, an expansion tank 200, and a connecting assembly 300. The housing 100 has a receiving chamber 101 formed therein. The housing 100 includes a bottom plate 110 and a first side plate 120 and a second side plate 130 connected to the bottom plate 110. The first side plate 120 and the second side plate 130 are disposed adjacent to each other. The expansion tank 200 is located within the receiving chamber 101. The expansion tank 200 includes a tank body 210, which extends along the height direction of the housing 100. One end of the connecting assembly 300 is connected to the side wall of the tank body 210, and the other end is connected to at least one of the first side plate 120 and the second side plate 130.

[0043] The hydraulic module 10 of the present application includes a box 100, an expansion tank 200 and a connecting assembly 300. Figure 2 The housing 100 has a chamber 101 inside, which houses components such as the buffer water tank 400 and the water supply pipeline 500. As will be readily understood, the water supply pipeline 500 includes not only pipes but also various control valves and a drive pump. The buffer water tank 400 stores hot water at a preset temperature and supplies it to external components for heating. For example, the water in the buffer water tank 400 can be used to supply components such as a hot water fan heater, floor heating, and a domestic water tank.

[0044] The expansion tank 200 can balance the water pressure changes in the water system connecting the buffer water tank 400 and external components. When the water temperature rises, the volume of the water will expand, and the expanded water in the system will be squeezed into the expansion tank 200, thereby achieving pressure balance of the water in the system within a certain range. It should be noted that Figure 2 In addition to illustrating the expansion tank 200 of the present application, a second expansion tank 600 connected to the water supply pipeline is also exemplified, one end of the water supply pipeline is connected to an external water source, and the other end is connected to a buffer water tank and / or an external component such as a domestic water tank. The external water source can supply water to the buffer water tank and / or the domestic water tank through the water supply pipeline. Therefore, the second expansion tank 600 is used to balance the water pressure changes on the water supply pipeline. Since the volume of the second expansion tank 600 is much smaller than that of the expansion tank 200, the second expansion tank 600 does not need to be additionally fixed after being connected to the pipeline. Of course, the second expansion tank 600 can also be fixed in a manner similar to that of the expansion tank 200 of the present application, and the present application does not impose any restrictions on this.

[0045] Please refer to Figure 3 and Figure 4The expansion tank 200 includes a tank body 210, which is the core of the expansion tank 200. The tank body 210 is typically made of metal, such as stainless steel or galvanized steel, and is capable of withstanding pressure and temperature fluctuations within the system. The interior of the tank body 210 is divided into two sections: one is an air bladder, which isolates the gas and water to prevent them from mixing; the other is a water storage space. When the water in the system expands due to temperature fluctuations, excess water enters the tank body 210 and is stored there.

[0046] In the present application, the housing 100 of the hydraulic module 10 includes a bottom plate 110 and a first side plate 120 and a second side plate 130 connected to the bottom plate 110. The first side plate 120 and the second side plate 130 are adjacent side plates. Furthermore, the tank body 210 of the expansion tank 200 extends along the height direction of the housing 100. That is, the tank body 210 is placed vertically, and the side walls of the tank body 210 are connected to at least one of the first side plate 120 and the second side plate 130 via a connecting assembly 300. This arrangement can reduce the space occupied by the bottom of the tank body 210 compared to the related art method of fixing the tank body 210 via a flange at the bottom of the tank body 210, thereby facilitating the fixing, connection, and removal of the tank body 210. Furthermore, the tank body 210 is connected to at least one of the first side panel 120 and the second side panel 130 via a connecting assembly 300. When disassembling the expansion tank, only the connecting assembly 300 can be removed from the outside, further enhancing the convenience of securing and disassembling the expansion tank 200. This arrangement facilitates maintenance and repair of the expansion tank 200. Furthermore, since the bottom of the tank body 210 occupies less space, the installation space for the water supply pipeline 500 within the housing 100 is increased, further facilitating the layout of the internal components of the hydraulic module 10.

[0047] In some embodiments, the connecting assembly 300 is connected to both the first side plate 120 and the second side plate 130 , thereby improving the reliability of fixing the expansion tank 200 in the tank body 100 .

[0048] In some embodiments, as Figure 4 and Figure 5 As shown, the connection assembly 300 includes a mounting plate 310 and at least one fixing member 320. For example, the number of fixing members 320 can be one, two, or more. The fixing member 320 is welded to the side wall of the tank body 210. The fixing member 320 is detachably connected to the mounting plate 310. The mounting plate 310 is connected to at least one of the first side panel 120 and the second side panel 130.

[0049] This embodiment proposes one of the structures of the connection assembly 300. Specifically, the connection assembly 300 includes a mounting plate 310 and a fixing member 320. The fixing member 320 is connected to the tank body 210 by welding. The welded connection has the advantages of high strength and corrosion resistance, which is conducive to improving the connection reliability between the fixing member 320 and the tank body 210. The fixing member 320 and the mounting plate 310 are detachably connected. For example, the fixing member 320 and the mounting plate 310 are connected by at least one of a bolt connection, a snap connection, and a hook connection. This arrangement is conducive to improving the convenience of installation, maintenance and replacement of the expansion tank 200. The mounting plate 310 is connected to at least one of the first side plate 120 and the second side plate 130, so that the expansion tank 200 is fixedly connected to the box body 100.

[0050] It is easy to understand that the mounting plate 310 can also be connected to the first side plate 120 and the second side plate 130 in a detachable manner, thereby further improving the convenience of installation, maintenance and replacement of the expansion tank 200.

[0051] In some embodiments, as Figure 4 and Figure 5 As shown, there are multiple fixing members 320 and they are spaced apart along the axial direction of the tank body 210, wherein the mounting plate 310 is connected to the first side plate 120, and the fixing member 320 is arranged opposite to the first side plate 120; or, the mounting plate 310 is connected to the second side plate 130, and the fixing member 320 is arranged opposite to the second side plate 130.

[0052] This embodiment proposes two ways of connecting the mounting plate 310 to the box body 100. Specifically, in the first way, Figure 4 As shown, the mounting plate 310 is connected to the first side panel 120. In this case, multiple fixings 320 are arranged relative to the first side panel 120, which can improve the convenience of connecting the fixings 320 and the mounting plate 310. The tank body 210 is fixedly mounted on the first side panel 120 through the fixings 320 and the mounting plate 310. In a second embodiment, the mounting plate 310 is connected to the second side panel 130 (not shown in the drawings). In this case, multiple fixings 320 are arranged relative to the second side panel 130, which can improve the convenience of connecting the fixings 320 and the mounting plate 310. The tank body 210 is fixedly mounted on the second side panel 130 through the fixings 320 and the mounting plate 310. The above two embodiments allow the tank body 210 to be fixedly mounted on one of the first side panel 120 and the second side panel 130, thereby facilitating the improvement of the convenience of connecting the tank body 210 to the box body 100.

[0053] In some embodiments, as Figure 6 and Figure 7As shown, the mounting plate 310 includes a first sub-plate 311 and a second sub-plate 312 connected to each other. The first sub-plate 311 is connected to the first side plate 120 , and the second sub-plate 312 is connected to the second side plate 130 .

[0054] This embodiment provides another method for connecting the mounting plate 310 to the tank body 100. The mounting plate 310 includes a first sub-plate 311 and a second sub-plate 312 that are connected to each other. The tank body 210 is connected to the first side plate 120 and the second side plate 130 via the fixing member 320, the first sub-plate 311, and the second sub-plate 312. In other words, the first side plate 120 and the second side plate 130 can jointly fix the expansion tank 200, thereby further improving the reliability of the tank body 210.

[0055] It should be noted that the connection between the first sub-plate 311 and the first side plate 120 and the connection between the second sub-plate 312 and the second side plate 130 means that the first sub-plate 311 and the first side plate 120 are in a relative positional relationship, and the second sub-plate 312 and the second side plate 130 are in a relative positional relationship, thereby facilitating the installation of the first sub-plate 311 and the first side plate 120 and the installation of the second sub-plate 312 and the second side plate 130. In addition, Figure 6 and Figure 7 The difference is that in Figure 6 In the embodiment, the fixing member 320 is connected only to the first sub-board 311 (or only to the second sub-board 312), and Figure 7 In the embodiment, the fixing member 320 is connected to both the first sub-board 311 and the second sub-board 312 .

[0056] The first sub-board 311 and the second sub-board 312 are connected to each other. Specifically, the first sub-board 311 and the second sub-board 312 can be made by an integrated molding process, or the first sub-board 311 and the second sub-board 312 can be connected as one by welding, connecting parts, etc., and this application does not impose any restrictions on this.

[0057] In some embodiments, as Figure 7 and Figure 8 Shown and referenced Figure 3 There are multiple fixing members 320, a portion of the multiple fixing members 320 is arranged opposite to the first side panel 120 and connected to the first sub-panel 311, and another portion of the multiple fixing members 320 is arranged opposite to the second side panel 130 and connected to the second sub-panel 312.

[0058] This embodiment proposes one method for connecting the fixing member 320 to the tank body 210. Specifically, multiple fixing members 320 are grouped on the tank body 210. This allows the multiple fixing members 320 disposed opposite the first side panel 120 to be conveniently detachably connected to the first sub-panel 311, thereby achieving a connection between the tank body 210 and the first side panel 120. At the same time, the multiple fixing members 320 disposed opposite the second side panel 130 can be conveniently detachably connected to the second sub-panel 312, thereby achieving a connection between the tank body 210 and the second side panel 130. This helps further improve the reliability of the tank body 210 being fixed within the box body 100.

[0059] In some embodiments, as Figure 7 and Figure 9 Shown and referenced Figure 3 The fixing member 320 includes a first sub-fixing member 321 and a second sub-fixing member 322 connected to each other. The first sub-fixing member 321 is arranged opposite to the first side panel 120 and connected to the first sub-panel 311, and the second sub-fixing member 322 is arranged opposite to the second side panel 130 and connected to the second sub-panel 312.

[0060] This embodiment proposes another method for connecting the fixing member 320 to the tank body 210. The fixing member 320 includes a first sub-fixing member 321 and a second sub-fixing member 322 that are interconnected. The tank body 210 is connected to the first side panel 120 via the first sub-fixing member 321 and the first sub-plate 311. Simultaneously, the tank body 210 is connected to the second side panel 130 via the second sub-fixing member 322 and the second sub-plate 312. This helps further improve the reliability of the expansion tank 200's fixation within the tank body 100.

[0061] It should be noted that the first sub-fixing member 321 and the second sub-fixing member 322 are connected to each other. Specifically, the first sub-fixing member 321 and the second sub-fixing member 322 can be made using an integrated molding process, or the first sub-fixing member 321 and the second sub-fixing member 322 can be connected as one by welding, connecting with connectors, etc. This application does not impose any restrictions on this.

[0062] In some embodiments, as Figure 4 As shown, the side of the fixing member 320 near the can body 210 is provided with a slot 323 that mates with the side wall of the can body 210. This arrangement allows the fixing member 320 to precisely mate with the side wall of the can body 210, thereby facilitating welding of the fixing member 320 to the side wall of the can body 210. It is easy to understand that if the fixing member 320 includes a first sub-fixing member 321 and a second sub-fixing member 322 that are connected to each other, then the side of the first sub-fixing member 321 and the second sub-fixing member 322 near the can body 210 are both provided with a slot 323 that mates with the side wall of the can body 210.

[0063] In some embodiments, as Figure 5 As shown, the fixing member 320 is provided with a hook 324, and the mounting plate 310 is provided with a hanging interface (not shown) that cooperates with the hook 324. In other words, the fixing member 320 can be mounted on the mounting plate 310 by hanging. This helps to improve the convenience and efficiency of disassembly and assembly of the expansion tank 200 and the mounting plate 310, and facilitates maintenance and repair of the expansion tank 200.

[0064] It should be noted that the fixing member 320 can be connected to the mounting plate 310 using both a hook connection and a bolt connection, and this application does not limit this. In addition, if there are multiple fixing members 320, some of the multiple fixing members 320 can be connected to the mounting plate 310 using a hook connection, and some can be connected to the mounting plate 310 using a bolt connection, and this application does not limit this either.

[0065] In some embodiments, as Figure 3 As shown, the distance between the tank body 210 and the first side panel 120 is equal to the distance between the tank body 210 and the second side panel 130. In other words, the distances between the tank body 210 and two adjacent side panels of the housing 100 are equal. This allows the tank body 210 to occupy less space in both directions, thereby reducing the space required after the expansion tank 200 is installed. This increases the installation space for components such as the water supply pipeline 500 and the control valve, thereby facilitating the layout of components within the housing 100 of the hydraulic module 10.

[0066] Furthermore, in some embodiments, Figure 3 As shown, the box body 100 also includes a top plate 140 arranged opposite to the bottom plate 110, the first side plate 120 and the second side plate 130 are both connected to the top plate 140, and the distance between the tank body 210 and the top plate 140 is smaller than the distance between the tank body 210 and the first side plate 120.

[0067] In this embodiment, the housing 100 further includes a top plate 140 disposed opposite the bottom plate 110, with the top plate 140 positioned above the bottom plate 110. Furthermore, the distance between the tank body 210 and the top plate 140 is smaller than the distance between the tank body 210 and the first side plate 120. This results in the tank body 210 occupying a smaller space in all three directions, thereby reducing the space required after the expansion tank 200 is installed. This further increases the installation space for components such as the water supply pipeline 500 and the control valve, thereby facilitating the layout of components within the housing 100 of the hydraulic module 10.

[0068] It should be noted that in Figure 3In the figures shown in , the box body 100 further includes a third side panel 150, which is rotatably connected to the first side panel 120. This allows the third side panel 150 to switch between a closed position and an open position. When the third side panel 150 is in the open position, the components within the accommodating chamber 101 are exposed; when the third side panel 150 is in the closed position, the third side panel 150 encloses the accommodating chamber 101 and is disposed opposite the second side panel 130.

[0069] In some embodiments, the connecting assembly 300 includes a mounting plate 310 and at least one clamp (not shown in the figure), the tank body 210 is clamped in the clamp, the clamp is connected to the mounting plate 310 in a detachable manner, and the mounting plate 310 is connected to at least one of the first side plate 120 and the second side plate 130.

[0070] This embodiment provides another structure for the connection assembly 300. The connection assembly 300 includes a mounting plate 310 and a clamp. The clamp can clamp the sidewall of the tank body 210 to achieve a connection between the tank body 210 and the first side plate 120 and / or the second side plate 130. In this way, a fixed connection between the expansion tank 200 and the housing 100 is achieved.

[0071] In some embodiments, the expansion tank 200 further includes an interface portion 220 connected to the tank body 210. The hydraulic module 10 further includes a buffer water tank 400, which is located below the expansion tank 200 and connected to the base plate 110. The interface portion 220 is in communication with the buffer water tank 400. In this embodiment, the tank body 210 is connected to the buffer water tank 400 via the interface portion 220, allowing the expansion tank 200 to balance pressure fluctuations in the water system connecting the buffer water tank 400 to external components. Because the expansion tank 200 is not fixed from the bottom, the bottom space of the expansion tank 200 is relatively large. The interface portion 220 can be connected to the connecting pipeline between the buffer water tank 400 and the external components through a pipe, thereby improving the convenience of connecting the expansion tank 200 and the buffer water tank 400.

[0072] In a second aspect, the present application provides a heat pump system. The heat pump system includes the hydraulic module 10 described in the first aspect. Compared to the related art method of securing the tank body 210 via a flange at the bottom of the tank body 210, this method reduces the space occupied by the bottom of the tank body 210, thereby facilitating easier connection and removal of the tank body 210. Furthermore, the tank body 210 is connected to at least one of the first side panel 120 and the second side panel 130 via a connecting assembly 300. When removing the expansion tank, only the connecting assembly 300 can be removed from the outside, further enhancing the ease of connection and removal of the expansion tank 200. This arrangement facilitates easier maintenance and repair of the expansion tank 200. Furthermore, since the space occupied by the bottom of the tank body 210 is reduced, the installation space for the water supply pipe 500 within the housing 100 is increased, further facilitating easier arrangement of the internal components of the hydraulic module 10.
