technical field

The invention relates to the field of cold chain transportation, in particular to a roof power installation device for a convection new energy refrigerated vehicle.

Background technique

At present, refrigerated vehicles are an indispensable tool for transporting some items. At present, a power installation box is installed on the roof of the current new energy refrigerated vehicles. The power installation box is equipped with a fully enclosed compressor and power conversion components, a fully enclosed compressor and Power conversion components are heat-generating components that generate a lot of heat.

The current structure of the power installation box is shown in FIG. 1 , which includes three major components: an upper shell (1), a lower shell (5) and a partition plate (3). The upper shell (1) and the lower shell (5) are matched together. , the partition plate (3) separates the space formed by the upper shell (1) and the lower shell (5) from the first chamber (501) and the second chamber (502), wherein the fully enclosed compressor and the power conversion module Installed in the first chamber (501), the condenser (4) is installed in the second chamber (502), the partition plate (3) is a complete plate without holes, the first chamber (501) Gas convection cannot be formed with the second cavity (502).
