Patent ID: 7059147

Claim:
A cooling system for a movable body, the cooling system comprising: a first heating element from which heat is absorbed; a refrigerator operated with the absorbed heat; wherein the refrigerator includes: an ejector pump, wherein the ejector pump ejects a fluid at a high speed that is heated by the first heating element to circulate refrigerant by using an entrainment effect of the fluid ejected at high speed; a radiator, wherein the radiator cools the refrigerant ejected from the ejector pump; and an evaporator, wherein the evaporator evaporates the refrigerant to generate refrigerating capacity; a second heating element cooled by the refrigerator; cooling mode selecting means for selecting and carrying out a cooling mode including a cooling air increase mode and a radiation air increase mode, the cooling air increase mode increasing an amount of air blowing on the second heating element in order to increase the cooling capacity for cooling the second heating element, the radiation air increase mode increasing an amount of air for radiation in order to increase the cooling capacity for cooling the second heating element.
