Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2022/054963
Kind Code:
A1
Abstract:
A heat exchanger that dissipates heat from an object to be heat exchanged to a heat exchange medium, with improved heat dissipation efficiency on the downstream side of the heat exchange medium. In the present invention, the upward-sloping surface 6b and the downward-sloping surface 6c of each wave 6 of a corrugated fin 5 interposed in a heat exchanger body are formed with alternating recessed and protruding ridges 10 in the thickness direction of the strip-shaped metal plate thereof. The inclination angle of each of the recessed and protruding ridges 10 is within the range of 10-60 degrees with respect to the main flow of a heat exchange medium 21, and the adjacent recessed and protruding ridges 10 are arranged in the same direction. This structure allows the heat exchange medium 21 flowing inside the corrugated fin 5 to circulate, thereby improving the heat dissipation performance on the downstream side of the heat exchange medium 21.
