Fuel cell system, box body structure thereof and manufacturing method of box body structure

Abstract

The invention discloses a fuel cell system, a box body structure thereof and a manufacturing method of the box body structure, and the manufacturing method of the box body structure comprises the following steps: manufacturing an aluminum profile into a main body barrel structure through an extrusion molding process; and machining the formed main body barrel structure into a sealed mounting structure through a machining process to obtain a box body. In the scheme, the main body barrel structure is manufactured through an extrusion molding process; the assembly of six planes of the box body structure can be effectively avoided, the assembly surface is reduced, the problem of the untight sealing of the box body is solved based on the sealed mounting structure of the box body, and the sealinginstallation of a fuel cell in the box body is realized, so that the waterproof effect of the fuel cell in the box body is ensured.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell system, its box structure, and a manufacturing method for the box structure. Background technique [0002] The existing fuel cell box scheme is a spliced ​​structure of 6 boxes. The box body is composed of six sides: front, back, left, right, upper, and lower parts. At this time, the box body needs to be sealed at each overlapping joint when assembling. The existing sealing solution is sealing strip sealing, but this This method cannot achieve complete sealing at the overlapping joints of the three surfaces, resulting in loose sealing; at the same time, this solution has too many cabinets during assembly, the sealing structure is complicated, and the assembly operation is cumbersome. [0003] Another existing fuel cell case solution is an aluminum alloy casting integral molding solution. The box body is divided into six sides: front, rear, left, right, upper and ...

AI Technical Summary

Problems solved by technology

The box body is divided into six sides: front, rear, left, right, upper and lower. Among them, the upper part is hollowed out, and sealing strips are arranged around it. In addition, the top cover is pressed and sealed, and the assembly points of fuel cell accessories are arranged at the bottom. and the side; the implementation of this solution requires mold opening and molding. Compared with the current situation where the configuration of auxiliary parts is changeable, the installation points of the cabinet accessories are changed, but this kind of cabinet structure cannot adapt to the change of the installation points, resulting in a single scope of application for the cabinet
