Title: Heat exchanger
Inventor: SHIRAKAWA HAJIME
IPC: F28F13/00
Filed: 1988-03-31
Abstract: PURPOSE:To improve heat transfer between first fluid and fin members, by a method wherein recessed and projected parts are formed on a first fluid passage, through which first fluid flows, and fin members employing a porous materials are extended in a second fluid passage, through which second fluid flows, while the fin members are engaged with the recessed and projected parts on the first fluid passage. CONSTITUTION:First fluid passing through a first fluid passage 15 flows along grooves 14 projected toward the center of the first fluid passage 15 while meandering and, therefore, turbulent flow is generated in the first fluid. A temperature boundary layer is hardly generated in the first fluid passage 15 due to the turbulent flow generated in the first fluid passage 15. Heat transfer between the first fluid and first plate members 10 as well as the heat transfer between the first fluid and second plate members 20 may be improved by the grooves 14 in such a manner. On the other hand, porous aluminum alloys 30 are welded by fusion to the first plate members 10 and the second plate members 20. Accordingly, heat transferred from the first fluid to the first and second plate members 10, 20 is transferred to the porous aluminum alloys 30 quickly. When the second fluid flows into the porous aluminum alloys 30, heat exchange is effected between the second fluid and the porous aluminum alloys 30.
