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 mutual independent heat exchanging pipe 1 and cooling Circulation line 2, hydraulic pump 3 and liquid storage device 4 are provided on cooling cycle pipeline 2, and 1 part of heat exchanging pipe is arranged in liquid storage device 4.
When the cooling system and refrigeration system to be used cooperatively, can be introduced in refrigeration system by heat exchanging pipe 1 Refrigerant carries out heat exchange with cooling cycle pipeline 2, since the heat exchanging pipe 1 and cooling cycle pipeline 2 of cooling system are mutual indepedent, Therefore heat exchange can be realized with the coolant liquid in cooling cycle pipeline 2, then lead to by heat exchanging pipe 1 in liquid storage device 4 Supercooling circulation line 2 treats cooling-part and cools down, reduce directly by heat exchanging pipe 1 treat cooling-part carry out it is cold The length of required heat exchanging pipe 1 when but cooling down, reduces the length of pipe and complexity of access refrigeration system, effectively overcomes Access refrigeration system pipeline it is long caused by the problem of being easy to happen coolant leakage.
Further, since between heat exchanging pipe 1 and cooling cycle pipeline 2 independently of each other, can be followed in heat exchanging pipe 1 and cooling It is passed through different liquid in endless tube road 2, lower-cost coolant liquid can be also passed through in cooling cycle pipeline 2, to drop The cost of low entire cooling system.
The cooling system with others can also be easy that the equipment of liquid leakage occurs and is used cooperatively since pipeline is long, The length of pipe to connect with equipment is reduced, and the cryogenic liquid of equipment itself can be utilized to realize the cooling drop for treating cooling-part Temperature, to which resource distribution be better achieved.
The inlet end and an outlet end of hydraulic pump 3 is both provided with third solenoid valve 5, need to hydraulic pump 3 carry out replace or When person repairs, the two third solenoid valves 5 that can control 3 both ends of hydraulic pump close the refrigerant pipeline 9 for being connected to hydraulic pump 3, from And easily hydraulic pump 3 can be disassembled from cooling cycle pipeline 2.
In the present embodiment, hydraulic pump 3 is adjustable-flow hydraulic pump, and the flow-rate adjustment of hydraulic pump 3 is according to portion to be cooled The temperature of part is controlled, and when part temperatures to be cooled are more than that ideal temperature is higher, are adjusted hydraulic pump 3, is made cooling cycle pipe The flow of coolant liquid in road 2 increases, and to improve the heat dissipation that cooling cycle pipeline 2 treats cooling-part 16, quickly reduces and waits for The temperature of cooling-part 16 makes component 16 to be cooled be operated in safe temperature range.When part temperatures to be cooled are slightly above managed When thinking temperature, hydraulic pump 3 can be adjusted, the flow of the coolant liquid in cooling cycle pipeline 2 is made to reduce, reduces the defeated of hydraulic pump 3 Go out power, to reduce power consumption while ensureing part temperatures to be cooled, realizes energy saving.
Flow control valve can also be set on cooling cycle pipeline 2, and hydraulic pump 3 at this time can be the constant hydraulic pressure of flow Pump can control flow when needing to adjust the coolant rate in cooling cycle pipeline 2 according to the temperature of component to be cooled The state of regulating valve, to realize the adjustment to the coolant rate in cooling cycle pipeline 2.
The first end of heat exchanging pipe 1 is provided with the first solenoid valve 6, and the second end of heat exchanging pipe 1 is provided with second solenoid valve 7, the first end and second end of heat exchanging pipe 1 can be closed when the refrigerant in refrigeration system need not be introduced, avoid refrigeration system Refrigerant in system is flowed into heat exchanging pipe 1, controls simpler convenience.
Preferably, heat exchanging pipe 1 is located at the formation of the part in liquid storage device 4 coil pipe 8, can be with the coolant liquid in liquid storage device 4 Contact area with bigger improves the heat exchange efficiency of heat exchanging pipe 1 and the coolant liquid in liquid storage device 4, enhances cooling system Cooling performance.Coil pipe 8 herein or other structures, as long as heat exchanging pipe 1 and the cooling in liquid storage device 4 can be increased The contact area of liquid improves the heat exchange efficiency of heat exchanging pipe 1 and the coolant liquid in liquid storage device 4.
The outlet end of hydraulic pump 3 is connected to the top of liquid storage device 4, and the input end of hydraulic pump 3 is connected under liquid storage device 4 Portion does not interfere with the cooling performance of cooling system, keeps away yet to ensure that the coolant liquid into cooling cycle pipeline 2 is liquid Exempt from hydraulic pump 3 to suck excessive gas and generate cavitation.
Refrigeration system and the heat exchange of cooling system are realized by liquid storage device 4 and coil pipe 8.Hydraulic pump 3 extracts liquid storage device 4 In coolant liquid treat cooling-part and cool down, absorb the heat that component to be cooled distributes, become high-temperature gas, then High-temperature gas enters from the top of liquid storage device 4 in liquid storage device 4, at this point, 8 kinds of flowings of coil pipe in liquid storage device 4 is low-temp low-pressure Liquid refrigerants, the low-temp low-pressure liquid refrigerants in coil pipe 8 exchange heat with the high temperature coolant outside coil pipe 8, reduce cold in fluid reservoir But liquid temperature, and it is made to become liquid phase from gas phase, and the temperature of liquid phase refrigerant is less than the temperature of component to be cooled so that fluid reservoir Coolant liquid in 4 can continue to absorb the temperature of component to be cooled in recycling next time, treat cooling-part and carry out cooling heat. Device 16 in order to control of component to be cooled in the present embodiment.
Preferably, it is connected with coolant liquid filling line 19 on liquid storage device 4, the 5th electricity is provided on coolant liquid filling line 19 Magnet valve 20.Coolant liquid filling line 19 can inject coolant liquid into liquid storage device 4 in real time, without stopping the operation of cooling system, It can be caused cold to avoid due to cooling system long-term work so that remain enough coolant liquids in liquid storage device 4 But liquid is insufficient, can not treat cooling-part and carry out effectively cooling problem, and can ensure cooling system safe and stable operation. 5th solenoid valve 20 can control the break-make of coolant liquid filling line 19, and coolant liquid is avoided to occur from coolant liquid filling line 19 Leakage.
It is of course also possible to be not provided with coolant liquid filling line 19, but liquid injection port is opened up on liquid storage device 4, is needing to add It, can be directly by coolant liquid out of liquid injection port injection liquid storage device 4 when adding coolant liquid.
In conjunction with shown in Figure 1, according to an embodiment of the invention, air-conditioning system includes refrigeration system and cooling system, should Cooling system is above-mentioned cooling system, and the inlet and outlet of the heat exchanging pipe 1 of cooling system is connected to refrigeration system, and draws The refrigerant for entering refrigeration system cools down to the coolant liquid in liquid storage device 4.
