Abstract
A cooling system comprising: an evaporator for evaporating a refrigerant by performing heat exchange with outside air; a condenser for condensing a gas refrigerant into a liquid refrigerant by making a refrigerant and a cooling medium perform heat exchange with each other; a gas refrigerant pipe and a liquid refrigerant pipe connecting the evaporator and the condenser; and the evaporator including: an upper part header provided in a highest position of the evaporator, and connected with the condenser by the gas refrigerant pipe, through the gas refrigerant pipe a gas refrigerant flowing; a lower part header provided in a lowest position of the evaporator, and connected with the condenser by the liquid refrigerant pipe, through the liquid refrigerant pipe a liquid refrigerant flowing; a middle header provided in an intermediate position between the upper part header and the lower part header, and connected with the condenser by the liquid refrigerant pipe, through the liquid refrigerant pipe the liquid refrigerant flowing; an upper part evaporator, arranged between the upper part header and the middle header, including an upper part steam generating tube having a first flow path for leading a refrigerant of the middle header to the upper part header while making the refrigerant of the middle header perform heat exchange with outside air and having a second flow path for leading a refrigerant of the lower part header to the upper part header while making the refrigerant of the lower part header perform heat exchange with outside air; and a lower part evaporator, arranged between the lower part header and the middle header, including a lower part steam generating tube having a third flow path inserted into the middle header while making a refrigerant of the lower part header perform heat exchange with outside air, the lower part steam generating tube communicated with the second flow path of the upper part steam generating tube.
