[0039] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0040] The present application provides a heat pump system, which can be a ground source heat pump, an air source heat pump, or an air-cooled heat pump, but is not limited thereto. For ease of explanation, the following heat pump systems are all traditional air source heat pumps.

[0041] The heat pump system of this embodiment includes an outdoor unit and a hydraulic module 100. The outdoor unit is used to exchange heat with the external environment, while the hydraulic module 100 is used to exchange heat between the refrigerant in the refrigerant pipe and the water in the water pipe, thereby heating or cooling the water, thereby outputting water at a set temperature and delivering it to a water storage device such as a water tank, or to a heat release device such as a floor heating pipe or radiator.

[0042] Among them, as mentioned in the background technology, the hydraulic module 100 includes a water pump, valves, a filter (also known as a filter assembly 20), a constant pressure water supply device, a water pump control cabinet, a box 10 and some pipeline structures 30. So many structures are arranged in one box 10, which will make the structure of the entire box 10 larger, and the panel structure of the box 10 will also be larger. In this way, the overall strength of the larger panel structure will be weakened, making it easy to deform. If the strength of the panel structure is to be guaranteed, the related technology generally adopts the method of increasing the thickness of the entire panel structure, which not only increases the cost, but also increases the weight of the entire box 10, which is not in line with the miniaturized design.

[0043] See also Figure 1 as well as Figure 2 The embodiment of the present application provides a hydraulic module 100, which includes a housing 10, a filter assembly 20, a buffer water tank 40 and an expansion tank (not shown).

[0044] The box body 10 serves as the exterior component of the entire hydraulic module 100. It not only includes the internal filter assembly 20, the buffer water tank 40 and the expansion tank for protection, but also enables the entire hydraulic module 100 to be an integrated design, which greatly saves the floor space of the machine room and improves space utilization.

[0045] The filter assembly 20 is mainly used to filter municipal water, and may include a magnetic filter and a soft water filter, such as Figure 2As shown, magnetic filters are primarily used to remove iron filings, iron powder, and other ferromagnetic impurities from fluids (including liquids, slurries, or gases). Their powerful adsorption capacity can capture ferromagnetic contaminants at the micron level, maintaining excellent filtration even at high flow rates. The primary purpose of a water softener 22 is to remove calcium and magnesium ions (the main components of scale formation) from water, thereby reducing water hardness.

[0046] By reducing the hardness of water, soft water filters can reduce the formation of scale, protect household appliances (such as water heaters, washing machines, etc.) from scale erosion, and extend the service life of the equipment.

[0047] The water inlet of the buffer water tank 40 is at the top and the water outlet is at the bottom. Temperature zoning can be achieved according to the different water temperatures of the inlet and outlet. According to the usage of the terminal (heating end), the excess heat source can be stored in the buffer water tank 40, and the heat source of the buffer water tank 40 can also be extracted to participate in the terminal temperature regulation. The terminal returns water to the bottom of the buffer water tank 40, and at the same time, the outdoor unit return water is also taken from the buffer water tank to achieve dynamic balance.

[0048] The expansion tank is mainly used to balance the pressure, for example, to prevent the internal pressure of the buffer water tank 40 from being too high, which may damage the equipment.

[0049] In the examples of this application, please refer to Figure 2 The box body 10 has a top plate, a bottom plate and multiple side plates, wherein the multiple side plates are connected in sequence to enclose a cavity, the top plate and the bottom plate are respectively connected to the opposite sides of the side plates and block the cavity, and the top plate, the bottom plate and the side plates are collectively referred to as a panel structure 11, wherein the panel structure 11 includes a main body 111 and a first reinforcement portion 112 extending from the edge of the main body 111, the first reinforcement portion 112 and the main body 111 are enclosed to form a hollow structure 11a, the hollow structure 11a formed by the first reinforcement portion 112 and the main body 111 can effectively disperse and resist external forces, prevent the panel structure 11 from being deformed or broken due to force, so that the panel structure 11 can still maintain its stability and integrity when bearing a large load, thereby extending its service life. On the other hand, the design of the hollow structure 11a can significantly reduce its weight while ensuring the strength of the panel structure 11.

[0050] It can be understood that the panel structure 11 of the top plate can have the first reinforcement part 112, or the panel structure 11 of the bottom plate can have the first reinforcement part 112, or the side plate can have the first reinforcement part 112. Of course, any two or any three of the bottom plate, side plate and top plate can have the first reinforcement part 112. In the embodiment of the present application, no further restrictions are made. The embodiment of the present application uses the panel structure 11 of the side plate having the first reinforcement part 112 for illustrative explanation.

[0051] Further, see Figure 3-4 The first reinforcement portion 112 includes a first plate portion 1121, a second plate portion 1122, a third plate portion 1123, a first curved transition portion 1125 connecting the main body 111 and the first plate portion 1121, a second curved transition portion 1126 connecting the first plate portion 1121 and the second plate portion 1122, and a third curved transition portion 1127 connecting the second plate portion 1122 and the third plate portion 1123. The first plate portion 1121, the second plate portion 1122, and the third plate portion 1123 constitute the main supporting structure of the first reinforcement portion 112. Together with the main body 111, they form a hollow structure 11a, providing additional rigidity and stability to the panel structure 11.

[0052] The design of the first arc-shaped transition portion 1125 , the second arc-shaped transition portion 1126 and the third arc-shaped transition portion 1127 makes the connection between the first reinforcement portion 112 and the body 111 smoother, thereby reducing the risk of stress concentration.

[0053] In some embodiments, the first curved transition portion 1125, the second curved transition portion 1126, and the third curved transition portion 1127 can all be connected using separate structures. Specifically, the first curved transition portion 1125 can be connected to the first plate portion 1121 and the body 111 by screws, welding, or other fixing methods, the second curved transition portion 1126 can be connected to the first plate portion 1121 and the second plate portion 1122 by screws, welding, or other fixing methods, and the third curved transition portion 1127 can be connected to the first plate portion 1121 and the second plate portion 1122 by screws, welding, or other fixing methods. Using separate curved transition portions makes the design of the entire reinforcement more modular. This means that during the manufacturing process, each component can be produced independently and then assembled, thereby improving production efficiency. If a curved transition portion is damaged or needs to be replaced, since it is a separate structure, it can be removed and replaced independently without affecting other parts of the reinforcement. This greatly simplifies the maintenance process and reduces maintenance costs.

[0054] In addition, the first arc-shaped transition portion 1125, the second arc-shaped transition portion 1126 and the third arc-shaped transition portion 1127 as separate structures can more flexibly adjust their shapes and sizes to adapt to different connection requirements, which helps to reduce stress concentration points and improve the mechanical properties and durability of the entire first reinforcement portion 112.

[0055] In other embodiments of the present application, the entire panel structure 11 can also be formed by bending a whole panel in sequence. By bending in sequence, a first curved transition portion 1125, a second curved transition portion 1126, and a third curved transition portion 1127 are formed at the bends. Since the entire panel structure 11 is formed by bending a whole panel, the connections between the parts are tighter, without additional connectors or gaps. This design helps to enhance the integrity and structural strength of the entire panel structure 11, making it more durable. On the other hand, the curved transition portions formed by bending reduce the number of connection points in traditional connection methods, thereby reducing the risk of structural failure caused by loose or damaged connection points.

[0056] Furthermore, the manufacturing process can be greatly simplified by using a single panel to bend and form the entire panel structure 11. Compared with the traditional multi-component connection method, this method reduces the number of components, reduces the difficulty of assembly, and improves production efficiency.

[0057] For further information, please refer to Figure 4 The first reinforcement portion 112 also includes a fourth plate portion 1124 and a fourth curved transition portion 1128 connecting the fourth plate portion 1124 and the third plate portion 1123. The fourth curved transition portion 1128 can also be connected to the fourth plate portion 1124 and the third plate portion 1123 using screws, welding, or other fixing methods. Alternatively, the fourth curved transition portion 1128 can be formed by bending. The presence of the fourth curved transition portion 1128 makes the connection between the fourth plate portion 1124 and the third plate portion 1123 smoother, helping to optimize stress distribution. When subjected to external forces, stress can be more evenly distributed throughout the entire panel structure 11, reducing the occurrence of stress concentration points, thereby improving the durability and service life of the panel.

[0058] The fourth plate portion 1124 is parallel to the main body 111, and the distance between the fourth plate portion 1124 and the main body 111 is h1, and h1 satisfies h1≤5mm. In this way, when hit by external force, the fourth plate portion 1124 can fit with the main body 111 to ensure a larger contact area, thereby dispersing the impact force, reducing the pressure per unit area, and improving the impact resistance of the panel structure 11.

[0059] Among them, h1 can be 1mm, 2mm, 3mm, 4mm, 5mm or a range between any two of the above numbers, and is set according to actual processing conditions.

[0060] It can be understood that the fourth arc-shaped transition portion 1128 is recessed toward the hollow structure 11a, making the connection between the fourth plate portion 1124 and the third plate portion 1123 smoother and more continuous, which helps to reduce structural mutations and stress concentration, thereby improving the overall strength and stability of the panel structure 11.

[0061] During the bending process, the first plate portion 1121 can be perpendicular to the main body 111, which can provide additional support force and enhance the overall stability of the panel structure 11. It is especially suitable for application scenarios that need to withstand large vertical loads. In addition, the first plate portion 1121 perpendicular to the main body 111 can more effectively utilize space, so that the panel structure 11 can achieve a more compact and efficient layout while maintaining high strength.

[0062] The second plate portion 1122 can be parallel to the main body 111, thereby increasing the volume of the hollow structure 11a, and further increasing the rigidity of the panel structure 11 and improving its anti-deformation ability; the third plate portion 1123 is perpendicular to the main body 111, so that the panel structure 11 is more stable when subjected to external force, and is suitable for application scenarios that need to withstand larger lateral loads.

[0063] It can be understood that when the panel structure 11 is bent in sequence, especially when the first arc-shaped transition portion 1125 is formed first, then the second arc-shaped transition portion 1126 is bent, and finally the third arc-shaped transition portion 1127 is formed, or when the fourth arc-shaped transition portion 1128 is first bent, then the second arc-shaped transition portion 1126 is bent, and then the first arc-shaped transition portion 1125 is bent, and finally the third arc-shaped transition portion 1127 is bent, and for the bending process, the bending of the panel structure 11 is generally achieved by a CNC bending knife. At this time, since the third arc-shaped transition portion 1127 is facing the hollow structure 11a, it is difficult to form the third arc-shaped transition portion 1127 by bending the panel structure 11 by a CNC bending knife. At this time, it is necessary to use a pressing knife process to bend the panel structure 11, thereby forming the third arc-shaped transition portion 1127.

[0064] However, for the pressing process, if the bending length is long, it is difficult to achieve bending. Therefore, in this application, please refer to Figure 4, the third arc-shaped transition portion 1127 includes multiple sub-arc-shaped transition portions 11271, and the multiple sub-arc-shaped transition portions 11271 are spaced apart along the length direction XX of the main body 111.

[0065] By decomposing a long bend into multiple short bends (i.e., multiple sub-arc transition portions 11271), the bending length of each sub-arc transition portion 11271 is relatively short, thereby reducing the difficulty of bending. Compared with a single long arc transition portion, multiple short arc transition portions can reduce stress concentration and reduce the risk of damage to components during the bending process.

[0066] Based on the fact that multiple sub-arc transition portions 11271 are spaced apart along the length direction XX of the main body 111 , the length of the sub-arc transition portion 11271 along the length direction XX of the main body 111 is h2, the thickness of the main body 111 is h3, and h2 and h3 satisfy h2≤2h3.

[0067] h2 can be 1.0h3, 1.1h3, 1.2h3, 1.3h3, 1.4h3, 1.5h3 or any two of the above numbers. No restrictions are imposed here. In this way, h2 is of appropriate length to reduce stress concentration, reduce the risk of damage to components during the bending process, and also reduce the difficulty of bending.

[0068] The total length of the multiple sub-arc transition portions 11271 along the length direction XX of the main body 111 is h4, and the length of the third plate portion 1123 along the length direction XX of the main body 111 is h5. h4 and h5 satisfy that h4≤0.15h5. When the total length of the multiple sub-arc transition portions 11271 does not exceed 15% of the length of the third plate portion 1123, it can ensure that the components can achieve a more compact and efficient spatial layout while maintaining sufficient strength, which helps to reduce the volume and weight of the panel structure 11 and improve the overall performance and efficiency.

[0069] The sub-arc transition portion 11271 of appropriate length can reduce stress concentration, making the stress distribution in the bending area more uniform, helping to enhance the structural strength of the panel structure 11 and improve the overall stability and durability.

[0070] In order to improve the aesthetics and deformation resistance of the entire panel structure 11, by arranging the first reinforcement part 112 on both the first edge and the second edge, the overall performance of the panel structure 11 is significantly improved, which not only enhances the structural stability and impact resistance of the panel structure 11, but also optimizes the stress distribution, improves the connection strength and overall aesthetics.

[0071] In another embodiment of the present application, the body 111 includes first edges disposed oppositely along its width direction YY and second edges disposed oppositely along its length direction XX. A first reinforcement portion 112 extends from the first edge, and a second reinforcement portion 113 extends from the second edge. The first reinforcement portion 112 and the second reinforcement portion 113 extend along the first and second edges of the body 111, respectively, providing additional support for the body 111. This design significantly enhances the strength and stability of the body 111 in the edge region, enabling it to better resist external loads and deformation.

[0072] Specifically, the second reinforcing portion 113 includes a fifth plate portion 1131 , a sixth plate portion 1132 and a seventh plate portion 1133 that are bent in sequence, and the sixth plate portion 1132 is located between the two second plate portions 1122 .

[0073] See Figure 5-6The fifth plate portion 1131 and the first plate portion 1121 are both perpendicular to the main body 111, the sixth plate portion 1132 and the second plate portion 1122 are relatively parallel and are in the same plane, and the seventh plate portion 1133 and the third plate portion 1123 are also perpendicular to the main body 111. In this way, the protruding heights of the first reinforcement portion 112 and the second reinforcement portion 113 relative to the main body 111 are consistent, which ensures the overall aesthetics while helping to disperse and alleviate the stress generated in the edge area when subjected to force, making the stress distribution more uniform and reducing stress concentration, thereby reducing the probability of the panel structure 11 being damaged due to excessive stress.

[0074] Please continue reading Figure 6 The dimension of the third plate portion 1123 along the length direction XX of the main body 111 is smaller than the dimension of the second plate portion 1122 along the length direction XX of the main body 111, that is, the parts of the second plate portion 1122 at both ends along the length direction XX of the main body 111 are not bent, and the dimension of the sixth plate portion 1132 along the width direction YY of the main body 111 is smaller than the dimension of the fifth plate portion 1131 along the width direction YY of the main body 111, that is, the parts of the fifth plate portion 1131 at both ends along the width direction YY of the main body 111 are not bent, thereby forming an avoidance area to provide an area for placing the third plate portion 1123, so that the first reinforcement portion 112 and the second reinforcement portion 113 fit tightly at the corners of the main body 111, thereby avoiding cutting hands while ensuring the overall aesthetics.

[0075] It should be understood that a crack stop groove (also known as "crack stop groove") is provided in the bent and unbent areas of the second plate portion 1122, and a crack stop groove is also provided in the bent and unbent areas of the fifth plate portion 1131. The design of the crack stop groove can avoid the generation of burrs, ensure safe operation, and effectively reduce the force required for forming, thereby assisting the panel structure 11 in successfully completing the bending.

[0076] In addition, please refer to the examples in this application. Figure 1 as well as Figure 2 An inspection port 11b can be opened on the panel structure 11 of the side panel, and the filter assembly 20 is arranged adjacent to the side panel, and the filter assembly 20 is arranged opposite to the inspection port 11b. In this way, it is convenient for the user to observe the operation of the filter assembly 20 through the inspection port 11b. After entering the box body 10 from the inspection port 11b, the maintenance personnel can directly and conveniently access the filter assembly 20 without moving or disassembling other components, which is convenient for replacing the filter element and cleaning the filter assembly 20.

[0077] In order to prevent dust, water and other foreign matter from entering the box body 10 through the inspection port 11b, an inspection panel 114 is provided on the side panel. The inspection panel 114 is movably installed at the inspection port 11b to open or cover the inspection port 11b. In order to facilitate the user to observe the operation of the internal filter assembly 20 or the operation of other components, the inspection panel 114 has a visual area 114a, which is arranged opposite to the filter assembly 20.
