Abstract

The invention relates to a low-conductivity core body and processing technology for a fuel cell. The core body includes a heat dissipation pipe, a heat dissipation belt, a main board and a guard plate. A corrosion-resistant layer and a corrosion-resistant insulating layer are provided inside and outside, the corrosion-resistant layer includes a dense oxide film made of alumina, and the corrosion-resistant insulating layer includes a corrosion-resistant insulating layer made of water-based epoxy resin, graphene and a mixed resin. Membrane, through the new processing technology of the core structure of the radiator, the electrical conductivity of the fuel cell radiator is reduced. Compared with the traditional fuel cell radiator, it has the characteristics of constant electrical conductivity, low production cost and high production efficiency. For the rapid development of fuel cells in the future, the mass production of fuel cell radiators will greatly promote it.

Description

technical field [0001] The patent of the present invention relates to the field of heat dissipation systems, in particular to a low-conductivity core body and a processing technology for fuel cells. Background technique [0002] With the development of the automobile industry and the improvement of the country's environmental protection requirements, the whole vehicle is required to be more environmentally friendly in the development direction. As a true "zero-emission, pollution-free" vehicle, hydrogen fuel cell vehicles are one of the main development directions of new energy and clean power vehicles in the future. Hydrogen fuel cell is a power generation device that directly converts the chemical energy generated by the reaction of hydrogen and oxygen into electrical energy through chemical reaction. It has the advantages of high power generation efficiency and low environmental pollution. The fuel cell generates a huge amount of heat, so it is necessary to control the t...
