Specific implementation mode
Present invention is further described in detail in the following with reference to the drawings and specific embodiments, but not as the limit to the present invention
It is fixed.
Shown in Figure 1, according to an embodiment of the invention, cooling system includes cooling line 1 and is arranged in cooling line 1
On hydraulic pump 2, the cold medium flux in cooling line 1 is adjustable.In the present embodiment, the refrigeration of the cooling system and air-conditioning system
Connection is realized between system, and it is cold to radiate as the controller 16 to refrigeration system using the refrigerant in refrigeration system
Matchmaker.
The cooling system by hydraulic pump 2 for that when being cooled down to the controller 16 of refrigeration system, can be driven and be cooled down
Refrigerant flowing in pipeline 1 so that the refrigerant of flowing can quickly take away the heat that controller 16 distributes, and accelerate controller 16
Cooling heat dissipation, while cooling effect of the cooling line 1 to controller 16 can be improved, simultaneously as the refrigerant in cooling line 1
Flow is adjustable so that and cooling system can adjust the cold medium flux in cooling line 1 according to the temperature of of controller 16 itself, from
And reduce power consumption while meeting guarantee 16 temperature of controller.
It is both provided with third solenoid valve 3 in the inlet end and an outlet end of hydraulic pump 2, is needing to replace hydraulic pump 2
Or when repair, the two third solenoid valves 3 that can control 2 both ends of hydraulic pump close the refrigerant pipeline 9 for being connected to hydraulic pump 2,
So as to which easily hydraulic pump 2 is disassembled from cooling line 1.

Refrigerant in refrigeration system is flowed by inlet pipe 4 in liquid storage device 8, cold with participating in radiating to controller 16 in liquid storage device 8
Matchmaker mixes, and then flows out liquid storage device 8 from outlet pipe 5 again, and flow back in the refrigerant pipeline 9 of refrigeration system.In refrigeration system
Refrigerant realizes heat exchange with the refrigerant in cooling line 1 in liquid storage device 8, so as to continuous by the refrigerant in refrigeration system
The heat that the refrigerant in cooling system is taken away from controller 16 is taken away, the refrigerant for participating in radiating to controller 16 is reduced
Temperature improves heat dissipation performance of the cooling system to controller 16.
In addition, liquid storage device 8 can also play the role of storing the refrigerant for participating in controller heat dissipation, due to liquid storage device
Refrigerant in 8 participates in cooling cycle, so if the influence of flow loss and flow-rate adjustment is not considered, the refrigerant in liquid storage device 8
Amount can remain unchanged substantially, can cause cavitation since coolant quantity is insufficient at work to avoid hydraulic pump 2, improve liquid
Stability and reliability when press pump 2 works reduce noise when hydraulic pump 2 works.Liquid storage device 8 is also so that refrigeration system simultaneously
Interior refrigerant is not directly into the cooling participated in cooling line 1 to controller 16, so as to avoid to cooling line 1
The cold medium flux in refrigeration system is adversely affected when interior cold medium flux is adjusted, and ensures the heat exchange of cooling system
Efficiency.
