Abstract: A heat exchanger having an adsorbing core is advantageously applied to a refrigerating system mounted on an automotive vehicle. The adsorbing core absorbs heat from coolant and gives heat to the coolant thereby to perform heat-exchanging operation.

Since the attracting layer is uniformly formed and firmly connected to the surface of the heat exchanging member, heat is quickly transferred between the attractant layer and the heat exchanging member.
