HEAT EXCHANGER FIN AND HEAT EXCHANGER USING HEAT EXCHANGER FIN

摘要

PURPOSE: A heat exchanger fin and heat exchanger using the same is provided to improve assemblability and performance of heat exchanger, and reduce parts count by constituting the heat exchanger fin as a single block. CONSTITUTION: A heat exchanger comprises a porous single block fin formed by foam molding an aluminum material and which has a plurality of ventilation holes(11) and a plurality of tube insertion holes(13) formed in lengthwise direction of the block fin; a plurality of tubes(2) inserted into tube insertion holes of the porous block fin in such a manner that both ends of the tube protrude outwardly from the tube insertion hole; and a header pipe(3) into which the portion of the tube protruded from the tube insertion hole is inserted so that the header pipe is communicated to tubes. A refrigerant inlet pipe(35) and a refrigerant outlet pipe(37) are connected to predetermined portions of the header pipe.
