<P>PROBLEM TO BE SOLVED: To provide a heat exchanger for heating, preventing heating efficiency of air passing between fins from being degraded, by dissipating heat generated in an electrical heating element to a refrigerant medium. <P>SOLUTION: A heat exchanger H for heating includes: a cooling medium tube 21 for circulating a cooling medium; an electrical heating element tube 22 separated from the tube 21 and housing an electrical heating element 20; a cooling medium fin 23 integrally provided to the outside face of the cooling medium tube 21; and an electrical heating element fin 24 integrally provided on the outside face of the electrical heating element tube 22. The electrical heating element fin 24 is separated from the cooling medium tube 21 that is adjacent to the electrical heating element tube 22, provided with the electrical heating element, and the cooling medium fin 23, which is provided in the cooling medium tube 21, so as to be brought into noncontact with each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
