Patent Abstract

Provided is a heat exchanger for an adsorption heat transformation device. The heat exchanger comprises a stack of parallel plates, wherein a plate of the stack comprises an inlet and an outlet. The inlet is connected to the outlet by a plurality of parallel channels through the plate. The channels have a diameter between 1 millimeter and 3 millimeters. A clearance between channels of consecutive plates of the stack is between 1 millimeter and 2 millimeters and a space between the plates is fillable with an adsorbent.
