AI Technical Summary
In existing hydrogen fuel cell systems, the heat exchange of solid hydrogen storage tanks is not direct enough. Traditional methods require circulation pumps that consume additional electricity, and in extreme weather conditions, hydrogen may not be released, affecting system performance.
A heat-conducting metal plate and heat-conducting pipe are used to connect the hydrogen fuel cell, hydrogen controller and solid hydrogen storage cylinder. Heat exchange is carried out by utilizing the anti-gravity heat absorption cycle principle of the heat-conducting pipe. A high-speed heat exchange channel is established at both ends of the hot and cold through the heat-conducting metal plate and heat-conducting pipe, realizing heat conduction without the need for electric drive.
It improves heat exchange efficiency, reduces power consumption, ensures that solid hydrogen storage cylinders can operate normally in extreme weather conditions, enhances the protection and installation positioning of the device, and is suitable for use in compact spaces.
