Abstract

A cooling system of an electronic device comprises a heat exchanger, a first refrigerant pipe, a circulation pump, a second refrigerant pipe and a cooling device, wherein the heat exchanger, the first refrigerant pipe, the circulation pump and the second refrigerant pipe are connected in sequence to constitute a first circulation system, the cooling device is connected between the second refrigerant pipe and the circulation pump in series, and the cooling device is placed outside the electronic device. When the electronic device operates, if the temperature of the outside is higher than that inside the electronic device, refrigerant circulates in the first circulation system to cool the electronic device; and if the temperature of the outside is lower than that inside the electronic device, the refrigerant passes through the cooling device, the refrigerant is cooled through the lower temperature of the outside. Compared with the prior art, the refrigerant is cooled through the cooling device placed outside the electronic device, refrigerating capacity of the heat exchanger is reduced, and electricity is saved.

Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
See also Fig. 1 and Fig. 2, the better embodiment of the cooling system of electronic equipment 100 of the present invention comprises a heat exchanger 10, one first refrigerant pipe 20, a circulating pump 30, one second refrigerant pipe 40, one first valve 50, a second valve 60 and a cooling device 70.Be provided with the refrigerant of the heat exchanger 10 of can flowing through in the first refrigerant pipe 20 and the second refrigerant pipe 40.
Electronic equipment 100 can be case type data center (container data center is called for short CDC), large-scale rack or other large-scale heater members, and it can produce lasting, a large amount of heats in the course of the work.In present embodiment, electronic equipment 100 is case type data center.
Heat exchanger 10 is placed in and is used for absorbing the heat that electronic equipment 100 produces in electronic equipment 100.Heat exchanger 10 can be air-conditioning equipment.
The first end connection heat exchanger 10 of the first refrigerant pipe 20 is derived for the refrigerant after the heat that will absorb heat exchanger 10 generations.
The first end of circulating pump 30 is connected in the second end of the first refrigerant pipe 20.The second end of circulating pump 30 connects respectively one first valve 50 and a second valve 60.
The first valve 50 is directly connected in the first end of the second refrigerant pipe 40.Second valve 60 is connected in the second refrigerant pipe 40 first ends by cooling device 70.Apparently, as a kind of switching device shifter, the first valve 50 and second valve 60 can replace with a triple valve, and the entrance of triple valve is connected in the second end of circulating pump 30, and two outlets of triple valve are connected to the second refrigerant pipe 40 and cooling device 70.
The second end of the second refrigerant pipe 40 is connected in heat exchanger 10 and is used for refrigerant delivery heat exchanger 10.
Heat exchanger 10, the first refrigerant pipe 20, circulating pump 30, the first valve 50 and the second refrigerant pipe 40 consist of one first circulatory system.Heat exchanger 10, the first refrigerant pipe 20, circulating pump 30, second valve 60, cooling device 70 and the second refrigerant pipe 40 consist of one second circulatory system.Circulating pump 30 provides power for refrigerant transmission in these two circulatory systems.In other embodiments, this circulating pump 30 also can be directly connected in the first end of the second refrigerant pipe 40.
Cooling device 70 is placed in top or outside other position of electronic equipment 100.Cooling device 70 is that cranky metal tube is with increasing heat radiation area.
During electronic equipment 100 running, if extraneous temperature is opened the first valve 50 and closes second valve 60 higher than the temperature of electronic equipment 100 inside, refrigerant is circulated in first circulatory system electronic equipment 100 is dispelled the heat.If extraneous temperature is lower than the temperature of electronic equipment 100 inside, close the first valve 50 and open second valve 60, refrigerant is circulated in second circulatory system, refrigerant is when apparatus for supercooling 70, utilize extraneous lower temperature that refrigerant is dispelled the heat, enter heat exchanger 10 through the cooled low temperature refrigerant of apparatus for supercooling 70 through the second refrigerant pipe 40, can reduce the refrigerating capacity of heat exchanger 10, be beneficial to the saving energy.
