HEAT EXCHANGER USING HEAT TRANSFER MATERIAL HAVING VAPOR ADSORPTION/DESORPTION FUNCTION

摘要

PROBLEM TO BE SOLVED: To improve heat transfer performance and to carry out miniaturization in an adsorbent heat exchanger such as an adsorption refrigerator.;SOLUTION: The adsorption heat exchanger adopts a porous body integral type heat transfer face having an abundance of heat transfer performance obtained by forming a porous membrane composed of pores with a diameter of several Å to several hundred Å on a surface of metal such as aluminum. It is composed so as to increase adsorption capacity and improve adsorption and desorption speed by taking advantage of being able to easily control an adsorption equilibrium characteristic by controlling the pore diameter during membrane formation. The heat exchanger uses a heat transfer face with an adsorption capacity increased by carrying an adsorbent such as silica gel in the pores on the surface of the porous body integral type heat transfer face, and filling or applying a conventional adsorbent such as silica gel on its surface.;COPYRIGHT: (C)2005,JPO&NCIPI
