Detailed description of the invention
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As depicted in figs. 1 and 2, the temperature control system of the present embodiment comprises First Heat Exchanger 11, the second heat exchanger 12, electronic component 13, heat abstractor 20, first throttle device 35 and subcooler 30.The second heat exchanger 12 is connected to realize flowing of refrigerant between with First Heat Exchanger 11.Subcooler 30 is arranged between the second heat exchanger 12 and First Heat Exchanger 11, subcooler 30 has the first opening 31, the second opening 32, the 3rd opening 33, the 4th opening 34, the first opening 31 is connected with the second opening 32, the 3rd opening 33 is connected with the 4th opening 34, the first opening 31 and the 3rd opening 33 are all connected with First Heat Exchanger 11, be provided with first throttle device 35, the second openings 32 and be connected with the second heat exchanger 12 between the 3rd opening 33 and First Heat Exchanger 11.Heat abstractor 20 is arranged between subcooler 30 and first throttle device 35 and absorbs the heat that electronic component 13 distributes, and heat abstractor 20 has refrigerant channel 21, and preferably, heat abstractor 20 contacts with electronic component 13.The temperature control system of the present embodiment also comprises compressor 17, separator 18 and four-way change-over valve 19, wherein, the mode of communicating of compressor 17, separator 18, four-way change-over valve 19, First Heat Exchanger 11 and the second heat exchanger 12 can adopt in existing air-conditioner the connected relation between corresponding component to realize process of refrigerastion.First throttle device 35 is preferably electromagnetic expanding valve.
The temperature control system of application the present embodiment, in the situation that first throttle device 35 is opened, the refrigerant being flowed out by First Heat Exchanger 11 heat abstractor 20 of can flowing through, and heat abstractor 20 has refrigerant channel 21, therefore, the refrigerant being flowed out by First Heat Exchanger 11 can flow through heat abstractor 20 refrigerant channel 21 and flow into the second heat exchanger 12, again because the refrigerant between First Heat Exchanger 11 and the second heat exchanger 12 is liquid refrigerants, liquid refrigerant temperature is lower, therefore, low temperature liquid refrigerant is lowered the temperature to heat abstractor 20.Because heat abstractor 20 absorbs the heat that electronic component 13 distributes, therefore, by the heat abstractor 20 after refrigerant cooling, electronic component 13 is lowered the temperature, the temperature of electronic component 13 is reduced, be equivalent to adopt refrigerant to lower the temperature to electronic component 13, due to the characteristic of refrigerant self, the cooling-down effect of refrigerant is more remarkable.As the above analysis, the temperature control system of the present embodiment has improved the radiating effect of electronic component 13.
In the present embodiment, between the first opening 31 and the second opening 32, have refrigerant first-class to, between the 3rd opening 33 and the 4th opening 34, have refrigerant second to, refrigerant first-class to refrigerant second to contrary.
Refrigerant and the electronic component 13 of heat abstractor 20 of flowing through carried out heat exchange, when the very high heat of its generation that causes of power of electronic component 13 larger, especially summer (being that electronic component 13 is under hot environment), flowing through the refrigerant of heat abstractor 20 possibly cannot be reduced to the temperature of electronic component 13 in rational scope, therefore, the temperature control system of the present embodiment also tool has the following advantages, because heat abstractor 20 is arranged between subcooler 30 and first throttle device 35, therefore, in the situation that first throttle device 35 is opened, the refrigerant flowing out through First Heat Exchanger 11 is divided into two-way, one road flows into the first opening 31 and flows into the second heat exchanger 12 to complete process of refrigerastion by the second opening 32, another road flows into the 3rd opening 33 flow into refrigerant channel 21 after first throttle device 35 after again, the pressure of the refrigerant of process first throttle device 35 reduces and is accompanied by the reduction of temperature.That is to say, the refrigerant of first throttle device 35 of flowing through is lowered the temperature again, refrigerant after cooling flows in heat abstractor 20 and has carried out heat exchange with electronic component 13 again, has improved the endothermic effect of the refrigerant in heat abstractor 20, and then has further improved the radiating effect of electronic component 13.
As shown in Figure 1, the temperature control system of the present embodiment also comprises that gas-liquid separator 40, the four openings 34 are connected with gas-liquid separator 40.Flow out and flow into gas-liquid separator 40 from the 4th opening 34 with refrigerants after electronic component 13 heat exchanges and that temperature raises, gas-liquid separator 40 will stay liquid refrigerants to deposit therein, prevent that liquid refrigerants from entering in compressor 17, causes the damage of compressor 17.
