See also Fig. 1, the better embodiment of the cooling system of electronic equipment 10 of the present invention comprises one first heat exchanger 20, one first refrigerant pipe 30, a circulating pump 31, one second refrigerant pipe 40, one second heat exchanger 50 and one the 3rd heat exchanger 60.The first heat exchanger 20, the first refrigerant pipe 30, circulating pump 31, the second refrigerant pipe 40 and the second heat exchanger 50 link to each other successively to form a circulatory system.Be provided with the refrigerant of can flow through the first heat exchanger 20 and the second heat exchanger 50 in the first refrigerant pipe 30 and the second refrigerant pipe 40.
The first heat exchanger 20 places and is used for absorbing the heat that electronic equipment 10 produces in the electronic equipment 10.
The second heat exchanger 50 utilizes liquid gas 51 gasification heat absorption to flow through the heat of refrigerant of the second heat exchanger 50 to cool off this refrigerant with absorption.In the present embodiment, this liquid gas 51 the 3rd heat exchanger 60 second heat exchanger 50 of behind seawater preheating, flowing through of flowing through first.
The first refrigerant pipe 30 places and is used between the first heat exchanger 20 and the second heat exchanger 50 and will be transferred to the first heat exchanger 20 through the second heat exchanger 50 cooled refrigerants.
The second refrigerant pipe 40 places between the first heat exchanger 20 and the second heat exchanger 50 refrigerant of the heat that is used for absorbing the first heat exchanger 20 to be transferred to the second heat exchanger 50 to cool off.
Circulating pump 31 is arranged between the first refrigerant pipe 30 and the second heat exchanger 50.This circulating pump 31 is used to the transmission of the refrigerant between the first heat exchanger 20 and the second heat exchanger 50 that power is provided.In the present embodiment, circulating pump 31 will pump in the first heat exchanger 20 through the second heat exchanger 50 cooled refrigerants.Apparently, in other embodiments, this circulating pump 31 also can be arranged between the second refrigerant pipe 40 and the second heat exchanger 50, is used for pumping into through the refrigerant of the first heat exchanger 20 the second heat exchanger 50.
This circulating pump 31 will pump into the first refrigerant pipe 30 and enter the first heat exchanger 20 through the refrigerant of the second heat exchanger 50 coolings, refrigerant first heat exchanger 20 of flowing through flows into the second heat exchanger 50 with the heat that absorbs the first heat exchanger 20 again and cools off, so move in circles, thereby reduce the temperature of electronic equipment 10, the service behaviour of guaranteeing each assembly in the electronic equipment 10 is not subjected to the impact of temperature.
In the present embodiment, liquid gas 51 is liquefied natural gas.In the prior art, the natural gas that gas field is produced needs elder generation through purified treatment, is liquefied through a succession of ultralow temperature again, makes it become liquefied natural gas, so that store and transportation.And client needs liquefied natural gas is gasified when using liquefied natural gas, and in this process, can absorb a large amount of heat.Liquid gas 51 also can be the liquid gas of other rear use of need to gasifying, such as liquid nitrogen etc.
