DETAILED DESCRIPTION

[0034] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0036] The present application aims at the problems that the inverter of the control system and the inverter of the air-conditioning system are arranged independently in the current industry, the water channel structure inside the inverter is complex, the cost is high, the processing and assembly procedures are complicated, and the arrangement of the water channel leads to a large thickness of the bottom plate, resulting in low overall success rate density, poor integration, leakage risk, low modularization and platformization, etc. A shell assembly applied to the inverter assembly is proposed, which reduces the space occupied by the water channel structure inside the shell bottom plate by a cooling component that can be detachably arranged inside the shell, and at least partially realizes the thinning of the shell bottom plate, thereby increasing the available space inside the shell, thereby increasing the power density of the inverter assembly; reducing the assembly procedures and raw material costs of the water channel structure in the existing inverter shell.

[0037] like Figures 1 to 5 As shown, an embodiment of the present application provides a housing assembly, wherein the housing assembly includes a housing 1 and a cooling member 2. A cavity is formed inside the housing 1, the top of the housing 1 has an opening in an open state, and the bottom of the housing 1 has a bottom plate in a closed state. The cooling member 2 is detachably arranged inside the housing 1, and is used to cool the components installed inside the housing 1.

[0038] At least two through openings are provided on the side wall of the housing 1 at intervals, so as to allow the cooling medium to enter the interior of the housing 1 or be discharged to the exterior of the housing 1 .

[0039] A cooling cavity 21 is formed inside the cooling member 2 for the cooling medium to flow therein. The cooling member 2 is provided with at least two connecting ports, each of which is connected to the cooling cavity 21, and each connecting port is connected to a through-port. The cooling medium can flow from the outside of the shell 1 through at least one through-port and at least one connecting port in sequence into the cooling cavity 21, and the cooling medium can flow out of the shell 1 through at least one through-port through at least one connecting port, thereby realizing the circulation of the cooling medium, so as to exchange heat with the heat inside the shell 1 during the circulation of the cooling medium, thereby realizing the cooling inside the shell 1.

[0040] By replacing the cooling channel arranged inside the bottom plate of the shell 1 in the prior art with the cooling cavity 21 of the cooling component 2, the structure of the shell 1 can be effectively simplified, and the processing difficulty of the shell 1 can be reduced. At the same time, it is beneficial to the thinning design of the bottom plate of the shell 1, reducing the weight of the shell 1 and reducing the material cost. At the same time, when the shell component is applied to the inverter assembly, it is beneficial to improve the power density of the inverter assembly.

Each heat-conducting protrusion 211 is protruded on at least one inner wall of the cooling cavity 21 in a direction perpendicular to the bottom plate of the shell 1 and abuts against the other inner wall on the opposite side. The heat transferred to the cooling component 2 is transferred from the outer surface of the cooling component 2 to the inner wall of the cooling cavity 21 and each heat-conducting protrusion 211. By providing the heat-conducting protrusion 211, the heat exchange area with the cooling medium can be effectively increased and the cooling efficiency can be improved.
