[0034] In the description of the embodiments of the present application, it should be noted that the terms "first direction" and "second direction" are based on the attached Figure 2 and attached Figure 4 These directional terms are only used to facilitate the description of the embodiments of the present application and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application.

[0035] Another embodiment of the present application provides a heat pump system, which includes a hydraulic module.

[0036] Heat pump systems include but are not limited to heat pump water heaters, heat pump air conditioners, heat pump floor heating, heat pump multi-generation (such as air conditioning and floor heating dual-generation, air conditioning and floor heating hot water trigeneration), etc.

[0037] The heat pump system is equipped with a water circulation pipeline. The main function of the hydraulic module is to exchange heat with the water from the water circulation pipeline to obtain hot water or cooling water. The water after heat exchange is then transported through the water circulation pipeline to the water storage device such as the water tank of the heat pump system or the terminal such as the fan coil, floor heating pipe, radiator, etc.

[0038] See also Figure 1 The hydraulic module includes a chassis 10, an electric heating tank 30, fasteners (not shown) and two connecting pipes 20.

[0039] The electric heating tank 30 is used for auxiliary heating. Specifically, the hydraulic module is provided with a heat exchanger (not shown). The water from the water circulation pipeline first flows into the heat exchanger, and then flows into the electric heating tank 30 after heat exchange in the heat exchanger. For heating, if the water temperature of the hot water flowing out of the heat exchanger does not meet the required temperature requirements, it needs to be heated in the electric heating tank 30. If the water temperature of the hot water flowing out of the heat exchanger meets the required temperature requirements, it does not need to be heated when passing through the electric heating tank 30. For cooling, the cold water flowing out of the heat exchanger does not need to be heated when passing through the electric heating tank 30.

[0040] One of the two connecting pipes 20 is used for allowing the water after heat exchange to flow into the electric heating tank 30 , and the other connecting pipe 20 is used for allowing the water flowing into the electric heating tank 30 to flow out of the electric heating tank 30 .

[0041] See also Figures 1 to 5 The chassis 10 is provided with a mounting area M having a plurality of assembly holes 11a. The electric heating tank 30 includes a tank body 31 and a support frame 32. The tank body 31 is provided with a pipe joint 311 correspondingly connected to the connecting pipe 20. The support frame 32 supports the tank body 31, and the support frame 32 is provided with a mounting hole 322a for communicating with at least one of the plurality of assembly holes 11a. The fastener is provided in the mounting hole 322a and an assembly hole 11a communicating with the mounting hole 322a, so that the support frame 32 is fastened to the chassis 10.

[0042] Specifically, the number of the mounting holes 322a is not limited. For example, the number of the mounting holes 322a may be two or more than two.

[0043] Any assembly hole 11a in the installation area M can be used to communicate with the same installation hole 322a. That is, during the installation of the electric heating tank 30, the installation hole 322a can be connected to the corresponding assembly hole 11a in the installation area M according to the position of the electric heating tank 30.

[0044] The mounting hole 322a is connected with at least one of the multiple assembly holes 11a, which means that the mounting hole 322a can be connected with only one assembly hole 11a at a time, or can be connected with two or more assembly holes 11a, depending on the specific sizes and positions of the mounting hole 322a and the assembly hole 11a.

[0045] It is understood that the connection described in the present application means that the mounting hole 322a and the assembly hole 11a can be penetrated by the same fastener. The situation where a part of the assembly hole 11a is connected to the mounting hole 322a but the fastener cannot be penetrated in the assembly hole 11a does not belong to the connection described in the present application.

[0046] See also Figure 1 and Figure 2 The support frame 32 may have a plurality of mounting holes 322a, and the chassis 10 may be provided with a mounting area M corresponding to each mounting hole 322a. That is to say, the electric heating tank 30 may be fastened to the chassis 10 by a plurality of fasteners, and a fastener is passed through a mounting hole 322a and an assembly hole 11a corresponding to and connected to the mounting hole 322a.

[0047] The installation area M and the installation hole 322a can have a one-to-one correspondence, that is, all assembly holes 11a within one installation area M can be connected to only one installation hole 322a, and the installation area M and the installation hole 322a can have a one-to-many relationship, that is, all assembly holes 11a within one installation area M can be connected to at least two installation holes 322a.

[0048] According to the number and location of the mounting holes 322a, the number of mounting areas M may be one or more.

[0049] For example, Figure 1 and Figure 2 The chassis 10 shown is provided with four installation areas M, and all the assembly holes 11 a in each installation area M are correspondingly connected to two installation holes 322 a.

[0050] It should be noted that when the number of mounting holes 322a corresponding to the same mounting area M is one, the mounting hole 322a can be connected to at least one assembly hole 11a among the multiple assembly holes 11a. When the number of mounting holes 322a corresponding to the same mounting area M is multiple, in the actual installation process of the electric heating tank 30, a part of the mounting holes 322a can be connected to the corresponding assembly holes 11a in this mounting area M, and another part of the mounting holes 322a can not be connected to the assembly holes 11a in this mounting area M (equivalent to some mounting holes 322a being staggered with the assembly holes 11a due to installation errors, etc.), or all the mounting holes 322a can be connected to the corresponding assembly holes 11a in this mounting area M respectively.

[0051] During the installation of the electric heating tank 30, the two connecting pipes 20 are first connected to the pipe joints 311 on the electric heating tank 30 in a one-to-one correspondence. After the connecting pipe 20 is installed, the mounting hole 322a will be connected to the corresponding mounting hole 322a in the installation area M, and then the fastener is inserted into the mounting hole 322a and an assembly hole 11a corresponding to the mounting hole 322a, and the electric heating tank 30 can be fixed on the chassis 10. Since the electric heating tank 30 is first connected to the connecting pipe 20, there is almost no position deviation between the pipe joint 311 and the connecting pipe 20, so that the misalignment between the pipe joint 311 and the connecting pipe 20 can be effectively avoided. At the same time, since a plurality of assembly holes 11a are provided in the installation area M, the mounting hole 322a can be connected to at least one assembly hole 11a of the plurality of assembly holes 11a, and there is almost no misalignment between the mounting hole 322a and the assembly hole 11a, so that the electric heating tank 30 can be fixed on the chassis 10 by the fastener. The hydraulic module of the embodiment of the present application effectively solves the problem of difficult assembly of the electric heating tank 30 and improves the installation convenience of the electric heating tank 30.

[0052] In one embodiment, please refer to Figure 3 The spacing distance between two adjacent assembly holes 11 a among the plurality of assembly holes 11 a may be no less than 1.5 mm, so as to effectively prevent the damage to the structural strength of the chassis 10 caused by the dense openings.

[0053] It can be understood that, when there are multiple installation areas M on the chassis 10 , the minimum spacing distance of 1.5 mm refers to the distance between any two adjacent assembly holes 11 a in the same installation area M.

[0054] The arrangement of the multiple assembly holes 11a in the same installation area M is not limited. For example, in one embodiment, refer to Figure 3A portion of the plurality of assembly holes 11a may be arranged in a plurality of rows, each row having at least one assembly hole 11a, and another portion of the plurality of assembly holes 11a may be arranged in a divergent shape with one assembly hole 11a located at the center and the other assembly holes 11a surrounding the outer periphery of the assembly hole 11a located at the center. The divergent shape may be Figure 2 The divergent shape shown is roughly plum blossom-shaped, and can also be a divergent shape such as a cross shape. It is equivalent to that multiple assembly holes 11a in the same installation area M can be arranged in different shapes to ensure that when the installation position of the electric heating tank 30 is greatly offset, the installation hole 322a can also be connected to the appropriate assembly hole 11a.

[0055] In other embodiments, the multiple assembly holes 11a may also be arranged in multiple rows, with at least one assembly hole 11a in each row, or the multiple assembly holes 11a may also be in a divergent shape with one assembly hole 11a located at the center and the other assembly holes 11a surrounding the outer periphery of the assembly hole 11a located at the center.

[0056] In one embodiment, please refer to Figure 4 and Figure 5 For a hydraulic module having multiple mounting holes 322a, among all the mounting holes 322a, at least one mounting hole 322a can extend along a first direction, and at least one mounting hole 322a can extend along a second direction intersecting the first direction, that is, the mounting hole 322a has at least one relatively long length dimension, which is the dimension of the mounting hole 322a extending along the first direction or the second direction.

[0057] Figure 2 and Figure 4 The first direction is perpendicular to the second direction. In other embodiments, the first direction may be oblique to the second direction.

[0058] See also Figure 4 The first direction may be parallel to the axial direction of the electric heating tank 30 . In other embodiments, the first direction may also be inclined relative to the axial direction of the electric heating tank 30 .

[0059] The first direction intersects with the second direction, so that the electric heating tank 30 can be adjusted in the first direction and the second direction to meet the position adjustment requirements of the electric heating tank 30 in different directions.

[0060] For example, see Figure 2 and Figure 3 At least two assembly holes 11a may be arranged in the first direction in the installation area M corresponding to the installation hole 322a extending along the first direction, so that the installation hole 322a extending along the first direction can match the appropriate assembly hole 11a in the first direction.

[0061] Please continue reading Figure 2 and Figure 3 There may also be at least two assembly holes 11a spaced apart along the second direction in the installation area M corresponding to the installation hole 322a extending along the second direction, so that the installation hole 322a extending along the second direction can match a suitable assembly hole 11a in the second direction.

[0062] In one embodiment, please refer to Figures 2 to 5 The same mounting area M can correspond to at least one mounting hole 322a extending along the first direction and at least one mounting hole 322a extending along the second direction, respectively. That is to say, among the mounting holes 322a corresponding to the same mounting area M, there are both mounting holes 322a extending along the first direction and mounting holes 322a extending along the second direction. Therefore, the flexibility of installation of the electric heating tank 30 can be improved.

[0063] In one embodiment, please refer to Figure 2 and Figure 4 The electric heating tank 30 may be provided with a plurality of support frames 32 , and the plurality of support frames 32 are spaced apart along the axial direction of the tank body 31 , that is, each support frame 32 is provided with a mounting hole 322 a .

[0064] It should be noted that Figure 4 The tank body 31 shown is roughly cylindrical. Therefore, the terms "axial" and "radial" appearing in the present application are defined with reference to the tank body 31 being cylindrical. It can be understood that the tank body 31 can also be other shapes. When the tank body 31 is other shapes, the terms "axial" and "radial" can represent the length direction and width direction of the tank body 31, respectively.

[0065] Providing a plurality of support frames 32 can not only improve the reliability of the support frames 32 supporting the tank body 31 , but also improve the reliability of the fastening connection between the electric heating tank 30 and the chassis 10 .

[0066] In one embodiment, please refer to Figure 4 and Figure 5 The support frame 32 includes a support body 321 and a mounting plate 322 having mounting holes 322a, the support body 321 is connected to the tank body 31, and the mounting plate 322 is located on the side of the support body 321 away from the tank body 31. By providing the support body 321 and a plurality of mounting plates 322 having mounting holes 322a, not only can the structural stability of the support frame 32 be effectively increased, but also the mounting holes 322a can be easily connected to the corresponding assembly holes 11a.

[0067] See also Figure 4 and Figure 5The support frame 32 can have two mounting plates 322, and the two mounting plates 322 are located on opposite sides of the tank body 31 in the radial direction. The chassis 10 is provided with a mounting area M corresponding to the mounting holes 322a on each mounting plate 322. That is to say, the support frame 32 can be fastened to the chassis 10 on opposite sides of the tank body 31 in the radial direction to improve the reliability of the fastening connection between the electric heating tank 30 and the chassis 10.

[0068] For example, see Figure 4 and Figure 5 The same mounting plate 322 has at least two mounting holes 322a, wherein at least one mounting hole 322a extends along a first direction, and at least one mounting hole 322a extends along a second direction intersecting the first direction.

[0069] In other embodiments, the mounting holes 322a on one of the two mounting plates 322 may extend along a first direction, and the mounting holes 322a on the other mounting plate 322 may extend along a second direction intersecting the first direction.
