HEAT RADIATION SYSTEM FOR STIRLING ENGINE AND COOLING CHAMBER HAVING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a heat radiation system for a stirling engine for sufficiently promoting heat radiation from a hot part without relying on an external power. SOLUTION: This heat radiation system for the sterling engine to radiate the heat generated in a compression stroke of a working medium of the stirling engine 1 consists of a refrigerating cycle using a natural refrigerant such as water and hydrocarbon, and comprises an evaporator 6 fitted to a hot part 2 of the stirling engine 1, a condenser 8 which is disposed higher than the evaporator 6 to condense the natural refrigerant, a vapor side pipe 7 and a liquid side pipe 11 which connect the evaporator 6 to the condenser 8 to circulate the refrigerant. The vapor refrigerant evaporated by the evaporator 6 is allowed to rise from the evaporator 6 to the condenser 8 through the vapor side pipe 7, and the liquid refrigerant condensed by the condenser 8 is circulated to the evaporator 6 through the liquid side pipe 11.
