Description

Technical Field

[0001] The utility model relates to the technical field of heat pump parts, in particular to an electric appliance box and a heat pump unit. Background Art

[0002] Most of the electric appliance boxes of the existing heat pump units are sheet metal boxes installed on the side wall of the housing of the outdoor unit of the heat pump unit, and the controller main board is placed flat in the sheet metal box. Since it is arranged in the outdoor unit of the heat pump unit, the main board is prone to dust accumulation due to being placed flat, which increases the risk of short circuit of the main board; at the same time, since the sheet metal box occupies a large space, the already compact space of the outdoor unit becomes more cramped, resulting in poor heat dissipation performance of the electrical components. To avoid dust accumulation on the controller main board, some heat pump units enclose the controller main board in the sheet metal box, but this setting method makes it inconvenient to disassemble and assemble the sheet metal box during later maintenance and inspection of the controller, and the heat dissipation effect is even worse.

[0003] To balance dust prevention and heat dissipation improvement, some heat pump units vertically arrange the controller main board on the air cavity on the left side of the middle partition of the outdoor unit of the heat pump unit to reduce dust accumulation and improve heat dissipation. However, the vertical arrangement method reduces the installation stability of the controller main board in the outdoor unit of the heat pump unit; at the same time, it also causes many problems with the wiring of the controller main board. For example, it is far from the user wiring port, resulting in long internal wires and difficult to accommodate, and the wiring is chaotic; at the same time, due to the vertical placement of the sheet metal box, there is still the problem of inconvenient disassembly and assembly of the sheet metal box during later maintenance and inspection of the controller.
