Abstract

The invention relates to a heat dissipation housing, which mainly solves the problems that an existing housing is poor in heat dissipation effect and does not have effectively waterproof and dustproof functions. The heat dissipation housing includes a shell and a bottom cover, the shell includes a top plate, a bottom plate, and a front plate, a first side plate, a rear plate and a second side plate which are connected end to end in sequence, the front plate, the first side plate, the rear plate and the second side plate are connected between the top plate and the bottom plate, thereby forming a cavity used for bearing a heat emission device, the shell is connected with the bottom cover through a sealing ring, a sealing ring installing groove is arranged on the connecting face of the shell and the bottom cover, the sealing ring is arranged in the sealing ring installing groove, a first connecting hole matched with the shell is arranged in the sealing ring, a second connecting hole matched with the shell is arranged in the bottom cover, by adoption of the technical scheme, the problems are well solved, and the heat dissipation housing can serve as a housing of a DC / DC converter.

Description

technical field

[0001] The invention relates to a heat dissipation shell. Background technique

[0002] The design of DC / DC converters is increasingly developing in the direction of high power and small size, and DC / DC converters with higher power density and smaller volume are favored by the market. However, in the existing DC / DC converter, as the integration density of the power devices in the DC / DC converter increases, the heat generation of the DC / DC converter is becoming more and more obvious, and the heat dissipation performance of the DC / DC converter needs to be improved urgently. . As the application requirements for high-power DC / DC converter equipment become more and more extensive, in order to meet the multi-functional market demand, more and more electronic components are integrated in the DC / DC converter, and the DC / DC conversion The external size of the converter is also increasingly restricted, so the DC / DC converter with small size and high power density ha...
