Heat exchanger

Abstract

A heat exchanger includes board members layered with each other, and a sintered member. A first passage and a second passage are alternately defined between the layered board members. The sintered member adsorbs or desorbs first fluid flowing through the first passage. Second fluid flowing through the second passage has a pressure higher than that of the first fluid. The sintered member is layered on a first face of the board member defining the first passage. The sintered member is pressurized on the first face of the board member in a direction of layering the board members. All outer periphery of the second passage is sealed.
