Title: Exhauster for condensate of heat exchanger
Inventor: JANG DONG YEON
IPC: F28F1/30
Filed: 2002-08-23
Abstract: PURPOSE: A condensate discharging device of a heat exchanger is provided to improve performance of the heat exchanger by actively discharging condensate down along the inclined surface with tilting a protruded slit and a base slit to the horizontal plane. CONSTITUTION: A heat exchanger is composed of a couple of headers(1,3) guiding gas; a tube(2) mounted between the headers to guide gas from one header to the other header; and fins(110) mounted between tubes to radiate heat. A protruded slit(114) is protruded in the fin, and inclined to the horizontal plane of a flat part(112) to discharge condensate down. The protruded slit and a base slit(115) are inclined to place the inflow portion of external air higher than the opposite portion of the slit. Thus, condensate in the surface of the fin is moved down and discharged through the protruded slit and the base slit. Heat exchange efficiency is improved by smoothly sliding condensate along the inclined surface according to flow of external air.
