Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this application.

For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] In addition, in this application, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0031] This application proposes a box body, which is applied to a heat pump unit and provides an installation space for various components of the heat pump unit. Among them, the heat pump unit includes components such as a plate heat exchanger 200, a liquid storage tank 300, a water pump 400, and a compressor 500. Please refer to Figures 1 to 6 In the embodiments of this application, the box body includes a housing 10, a first bracket assembly 20, a second bracket assembly 30, and a support plate 40.

[0032] The housing 10 is provided with an installation cavity inside. The first support assembly 20 is connected to the peripheral wall of the installation cavity. The support plate 40 is fixedly installed on the bottom wall of the installation cavity. The two sides of the second support assembly 30 are respectively connected to the first support assembly 20 and the support plate 40, so as to be suspended in the installation cavity and divide the internal installation space of the installation cavity into an upper installation space and a lower installation space.

[0033] The housing 10 is usually formed by splicing multiple plates. In Figures 1 to 3 and Figure 5 some plates of the housing 10 have been omitted for the convenience of display. Usually, a fan cavity is also provided inside the housing 10, and the fan cavity is used to install the fan of the heat pump.

[0034] The first support assembly 20 can be connected to the peripheral wall of the installation cavity through connection relationships such as threaded connection, snap connection, welding, etc. Similarly, the support plate 40 can also be fixedly installed on the bottom wall of the installation cavity through connection relationships such as threaded connection, snap connection, welding, etc.

[0035] The two sides of the second support assembly 30 are respectively connected to the first support assembly 20 and the support plate 40 means that the opposite sides or adjacent sides of the second support assembly 30 respectively establish connection relationships with the first support assembly 20 and the support plate 40. Specifically, the connection relationships can be threaded connection, riveting, welding, etc. Preferably, the opposite sides of the second support assembly 30 respectively establish connection relationships with the first support assembly 20 and the support plate 40.

[0036] It should be emphasized that the second support assembly 30 does not need to establish a direct connection relationship with the installation cavity. The indirect connection relationship it establishes through the first support assembly 20 and the support plate 40 means that during the assembly of the box body, the first support assembly 20 and the support plate 40 can be first installed in the installation, and then the second support assembly 30 is assembled.

[0037] The first support assembly 20 and / or the second support assembly 30 are used to respectively fix the plate heat exchanger 200, the liquid storage tank 300 and the water pump 400, so that the plate heat exchanger 200, the liquid storage tank 300 and the water pump 400 are installed in the upper installation space. The bottom wall of the installation cavity is used to fix the compressor 500, so that the compressor 500 is installed in the lower installation space.

[0038] The casing provided by the present application, through the above structural arrangement, the plate heat exchanger 200, the liquid storage tank 300, and the water pump 400 can be fixed on the first support assembly 20 and / or the second support assembly 30 by connection means such as threaded connection, snap connection, welding, etc., so as to be installed in the upper installation space. Similarly, the compressor 500 can be fixed on the bottom wall of the installation cavity by connection means such as threaded connection, snap connection, welding, etc., so as to be installed in the lower installation space. Thus, during the assembly of the heat pump unit, this casing can form two different installation spaces to respectively fixedly install the plate heat exchanger 200, the liquid storage tank 300, the water pump 400, and the compressor 500, thereby making full use of the installation space of the installation cavity to fixedly install different components, optimizing the spatial layout of the components in the internal installation space, and facilitating the miniaturization of the heat pump unit.

[0039] In some examples, as Figures 1 to 4 shown, the first support assembly 20 includes a fixing frame 21. The fixing frame 21 is connected to the peripheral wall of the installation cavity and encloses a first installation portion for fixedly installing the plate heat exchanger 200. On the side of the fixing frame 21 away from the peripheral wall of the installation cavity, there is also a second installation portion for fixedly installing the liquid storage tank 300. Among them, the second support assembly 30 is connected to the bottom of the fixing frame 21.

[0040] Such an arrangement aims to fixedly install the plate heat exchanger 200 in the upper installation space adjacent to the peripheral wall of the installation cavity and make the plate heat exchanger 200 adjacent to the liquid storage tank 300, so as to further optimize the spatial layout of the components of the heat pump unit. In addition, the second support assembly 30 is connected to the bottom of the fixing frame 21, reducing the interference of the second support assembly 30 on the liquid storage tank 300.

[0041] In some examples, as Figure 3 and Figure 4 shown, the first support assembly 20 further includes a bearing seat 22. The bearing seat 22 is connected to the peripheral wall of the installation cavity, and the bearing seat 22 forms a bearing surface 221 for bearing the plate heat exchanger 200 below the first installation portion.

[0042] Such an arrangement aims to play a role in supporting the plate heat exchanger 200 through the bearing surface 221 on the bearing seat 22. If the fixing frame 21 does not fully fix the plate heat exchanger 200 and the plate heat exchanger 200 drops downward under the action of gravity, the bearing surface 221 can bear the plate heat exchanger 200 to prevent the plate heat exchanger 200 from falling.

[0043] In some examples, as Figure 3 and Figure 4 shown, the first support assembly 20 further includes a spacer block 23. The spacer block 23 is connected to the peripheral wall of the installation cavity and is located inside the fixing frame 21 to space the plate heat exchanger 200 from the peripheral wall of the installation cavity.

[0044] With such a setting, it is intended to space the plate heat exchanger 200 from the peripheral wall of the installation cavity through the isolation block 23, avoiding direct contact between the plate heat exchanger 200 and the peripheral wall of the installation cavity, and improving the reliability of the operation of the plate heat exchanger 200. In addition, threaded holes, blind holes, etc. can be provided on the isolation block 23, and when assembling the plate heat exchanger 200, the plate heat exchanger 200 can be pre-mounted on the isolation block 23.

[0045] In some examples, such as Figure 3 and Figure 4 as shown, on the side of the fixing frame 21 away from the peripheral wall of the installation cavity, there protrudes an installation rib 211 extending in the vertical direction, and the installation rib 211 is provided with a second installation part. With such a setting, when the liquid storage tank 300 is installed on the second installation part, the peripheral side of the liquid storage tank 300 abuts against the installation rib 211, so as to increase the distance between the liquid storage tank 300 and the plate heat exchanger 200, and improve the reliability of the heat pump unit.

[0046] Among them, there are various installation methods for the liquid storage tank 300 to be installed on the second installation part. In one example, the installation rib 211 is provided with a groove to form the second installation part, and a hanging buckle is provided on the peripheral side of the liquid storage tank 300 to cooperate with the groove, so as to be hung on the groove on the installation rib 211. In another example, the installation rib 211 is provided with a threaded hole to form the second installation part, and the liquid storage tank 300 is threadedly connected to the threaded hole through a hoop.

[0047] In some examples, such as Figures 1 to 6 as shown, the second bracket assembly 30 includes a horizontal plate 31 and a support block 32. The two sides of the horizontal plate 31 are respectively connected to the first bracket assembly 20 and the support plate 40. The support block 32 is fixedly installed on the side surface of the horizontal plate 31 facing away from the lower installation space, and the support block 32 is provided with a support surface for supporting the water pump 400.

[0048] With such a setting, it is intended to support the water pump 400 through the support surface of the support block 32, so as to reduce the contact between the second bracket assembly 30 and the water pump 400.

[0049] In some examples, such as Figure 5 and Figure 6 as shown, the second bracket assembly 30 further includes a support pad 33 provided on the support surface. With such a setting, it is intended to absorb the vibration generated when the water pump 400 operates through the support pad 33, so as to avoid the connection relationship between the components being affected by the vibration and becoming loose.

[0050] In some examples, such as Figure 5 and Figure 6As shown, the second support assembly 30 further includes a plurality of sub-supports 34, and the plurality of sub-supports 34 are respectively fixedly installed on the horizontal plate 31. The sub-supports 34 are used to fix the pipeline communicated with the liquid storage tank 300. Such a setting aims to improve the stability of the pipeline, avoid the pipeline from shaking and colliding, and cause the pipeline to rupture.

[0051] In one example, the sub-support 34 includes a pipe clamp 341 for clamping and fixing the pipeline, and the pipe clamp 341 is directly fixedly connected to the horizontal plate 31; in another example, the sub-support 34 further includes a connecting plate 342 fixedly connected to the pipe clamp 341, and the pipe clamp 341 is fixedly connected to the horizontal plate 31 through the connecting plate 342.

[0052] In some examples, as Figure 1 shown, the box body further includes a top beam 50, at least part of the top beam 50 is fixedly installed on the top wall of the installation cavity, and the support plate 40 extends vertically to the top wall of the installation cavity and is fixedly connected to the top beam 50. Such a setting aims to improve the stability of the support plate 40, thereby indirectly improving the stability of the second support assembly 30.

[0053] This application also proposes a heat pump. Please refer to Figures 1 to 6 , this heat pump includes a plate heat exchanger 200, a liquid storage tank 300, a water pump 400, a compressor 500 and a box body. The specific structure of the box body refers to the above embodiments. Since this heat pump adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. Among them, the plate heat exchanger 200, the liquid storage tank 300 and the water pump 400 are respectively fixed by the first support assembly 20 and / or the second support assembly 30 to be installed in the upper installation space, and the compressor 500 is fixed by the bottom wall of the installation cavity to be installed in the lower installation space.
