ELECTRICAL APPLIANCE BOX, DOMESTIC ELECTRICAL APPLIANCE AND AIR-CONDITIONER HAVING EASILY COMBUSTIBLE AND EASILY INFLAMMABLE REFRIGERANT

摘要

Disclosed are an electrical appliance box, a domestic electrical appliance and an air-conditioner having an easily combustible and easily inflammable refrigerant, used for improving the heat dissipation performance of the electrical appliance box. The electrical appliance box comprises a box body (2) and a box cover (1), wherein the box body (2) and the box cover (1) fit together, the box body (2) is a metal box body and has an accommodating cavity (9); heat sink fins (3) are provided outside the box body (2), and the heat sink fins (3) are an integral structure with the box body (2). The above-mentioned technical solution only has two separate portions to be assembled together: the box cover (1) and the box body (2). A metal material is used for the box body (2), and the box body (2) is an integral structure with the heat sink fins (3) such that the heat dissipation performance is greatly increased.
