Description

technical field [0001] The invention relates to the technical field of metal fuel cells, and more specifically, the invention relates to a metal fuel cell heat dissipation structure and heat dissipation method. Background technique [0002] At present, during the working process of metal fuel cells (such as aluminum-air batteries), the reaction of the entire power generation system is an exothermic reaction, so most of the working process of metal fuel cells needs to be cooled. The metal fuel cell cooling scheme adopted in the prior art is: cool down by cooling fans, and the greater the amount of reaction liquid used in the power generation system, the greater the working power of the cooling fans. [0003] However, the heat dissipation fan adopted in the prior art will generate relatively loud noises during operation, and the heat dissipation fan will inevitably occupy additional space, resulting in a low space utilization rate of the existing metal fuel cell power generati...

Problems solved by technology

[0005] In order to solve the problems of high noise, low space utilization rate and unsatisfactory heat dissipation effect in the existing metal fuel cell heat dissipation scheme, the present invention innovatively provides a metal fuel cell heat dissipation structure and heat dissipation method. The liquid return pipe is used as the return line from the battery reactor to the reaction liquid tank, and the superconducting flat heat pipe and the flat liquid return pipe are bonded together by heat-conducting glue, so as to utilize the strong thermal conductivity of the superconducting flat heat pipe to flow the liquid back into the liquid pipe. Most of the heat of the overheated high-temperature reaction liquid is lost, and part of the heat is lost through the flat liquid return pipe itself. The invention effectively realizes the silent power generation of the metal fuel cell, and has outstanding advantages such as high space utilization rate and good heat dissipation effect.
