Abstract: A cooling system for a fuel cell is provided to deliver bulk of heat with very little loss without separate power for the circulation of work fluid, and to reduce volume of the complete system. A cooling system(20) for a fuel cell comprises an evaporation part(21) which evaporates and discharges gaseous work fluid by allowing liquefied work fluid to absorb heat; a condensation part(22) condensing gaseous work fluid evaporated from the evaporator; a gas transfer pipe(26) transferring gaseous work fluid to a condenser; and a liquid transfer pipe(27) transferring liquefied work fluid to the evaporator.

Abstract: PURPOSE: An evaporator with a flat bifacial evaporative surface for a loop heat pipe, a loop heat pipe with the same, and a heat transfer method using the same are provided to cool heat rapidly and stably by processing the heat of a heating source delivered to both surfaces of the evaporator simultaneously. CONSTITUTION: An evaporator(100) with a flat bifacial evaporative surface and a loop heat pipe comprises a housing(110), a flat plate-shaped wick(120), a spacer frame(130). A pair of wicks is installed inside the housing. The spacer frame comprises a plate wall. The plate wall divides the space between one-sided surfaces facing the wick and a space between the other surface of the wick and the housing into a liquid actuating fluid receiving area and a gaseous actuating fluid flowing area.
