Fig. 1 is a schematic structural view of some embodiments of a cabinet air conditioning heat dissipation system according to the present disclosure. The cabinet air conditioner cooling system includes: the compressor 1, the condenser group 2, the throttling device 3 and the evaporator group 4 which are sequentially connected to form a refrigerant loop (refer to a refrigerant loop shown by thickened lines in fig. 1), wherein an exhaust port 1a and an air suction port 1b of the compressor 1 are respectively communicated with a refrigerant inlet of the condenser group 2 and a refrigerant outlet of the evaporator group 4. Fig. 1 shows an example of a refrigerant circuit and various components forming the refrigerant circuit, but is not limited to the refrigerant circuit form and components forming the refrigerant circuit shown in fig. 1.

The cabinet air conditioner heat dissipation system further comprises: a gas-liquid separator 5, a vortex tube 6 and an electric box radiator 7. The inlet 5a of the gas-liquid separator 5 is connected to the condenser unit 2, and is configured to perform gas-liquid separation on the gas-liquid mixed refrigerant from the condenser unit 2. The gas-liquid separator 5 may mix the gas-liquid mixture refrigerant inputted from the inlet 5a with the gas refrigerant and the liquid refrigerant, and output the gas refrigerant outwards through the gas outlet 5b and output the liquid refrigerant outwards through the liquid outlet 5 c.

An inlet 6a of the vortex tube 6 is communicated with an air outlet 5b of the gas-liquid separator 5, and is configured to perform vortex separation on the gaseous refrigerant separated by the gas-liquid separator 5. The vortex tube 6 has a vortex chamber, and when the high-pressure gaseous refrigerant is injected into the vortex chamber, the high-pressure gaseous refrigerant rotates at a high speed to flow to the hot air end outlet of the vortex tube, a part of air flows out from the hot air end, and after the rest of air is blocked, the air reversely rotates at the same rotation speed at the inner ring of the original air flow and flows to the cold air end of the vortex tube. In this process, the two streams undergo heat exchange, the inner stream becomes very cold and exits the cold end of the vortex tube, and the outer stream becomes very hot and exits the hot end of the vortex tube. Thus, the vortex tube can efficiently generate low-temperature gas.

The electric box radiator 7 is arranged in an electric box 8 of the cabinet air conditioner, and an inlet 7a of the electric box radiator 7 is communicated with a cold air outlet 6b of the vortex tube 6 so as to radiate heat of the electric box 8 through the refrigerant separated by the vortex tube 6. Components for realizing control functions and the like in the cabinet air conditioner are arranged in the electric box 8 and normally operate at a proper temperature.

According to the embodiment, the gas-liquid separator 5 obtains a high-pressure gaseous refrigerant from the refrigerant loop of the cabinet air conditioner to be input into the vortex tube 6, and then the low-temperature gaseous refrigerant separated by the vortex tube 6 is input into the electric box radiator 7, so that effective heat dissipation of components in the electric box 8 is realized, the components in the cabinet air conditioner electric box work at an adaptive environment temperature, the service life damage of the components in the electric box 8 under the high-temperature environment working condition is reduced, the service life of the components in the electric box 8 is prolonged, and the service life of the cabinet air conditioner is further prolonged.

In addition, as the high-pressure gaseous refrigerant introduced into the vortex tube 6 comes from the refrigerant loop of the cabinet air conditioner, an additional air compression device can be omitted, the cooling effect of the vehicle-mounted electronic cabinet is realized by the circulation of the cabinet air conditioner refrigerant, the heat dissipation requirement of the electric box 8 is met, and the space occupation of a cabinet air conditioner heat dissipation system is saved.

Referring to fig. 1, in some embodiments, the condenser bank 2 includes a first condenser 21 and a second condenser 22 connected in series, an inlet 21a of the first condenser 21 being in communication with the discharge port 1a of the compressor 1, an outlet 21b of the first condenser 21 being in communication with an inlet 22a of the second condenser 22, an inlet 5a of the gas-liquid separator 5 being in communication with an outlet 21b of the first condenser 21, and a hot gas outlet 6c of the vortex tube 6 being in communication with an inlet 22a of the second condenser 22.

In this embodiment, the hot gas outlet 6c of the vortex tube 6 is in communication with the inlet 22a of the second condenser 22, so that the gaseous refrigerant discharged from the hot gas outlet 6c of the vortex tube 6 re-enters the refrigerant circuit to ensure stable refrigerant circulation in the refrigerant circuit. And, the refrigerant discharged from the outlet 21b of the first condenser 21 is merged and then secondarily cooled by the second condenser 22, thereby preventing the refrigerant of different temperatures outputted from different circuits from adversely affecting the throttling effect when entering the throttling device 3.

In fig. 1, the cabinet air conditioner heat dissipation system may further include a first check valve 91. A first check valve 91 is provided in the refrigerant flow path between the hot gas outlet 6c of the vortex tube 6 and the inlet 22a of the second condenser 22, and is configured to be in one-way conduction from the hot gas outlet 6c of the vortex tube 6 to the inlet 22a of the second condenser 22.

By arranging the first check valve 91 on the refrigerant flow path between the hot gas outlet 6c of the vortex tube 6 and the inlet 22a of the second condenser 22, the high-pressure refrigerant in the refrigerant loop is prevented from flowing back to the hot gas outlet 6c of the vortex tube 6 to affect the normal operation of the vortex tube 6.

Referring to fig. 1, in some embodiments, the outlet 22b of the second condenser 22 is in communication with the throttling device 3, and the liquid outlet 5c of the gas-liquid separator 5 is in communication with the outlet 22b of the second condenser 22.

The liquid outlet 5c of the gas-liquid separator 5 is communicated with the outlet 22b of the second condenser 22, so that the liquid refrigerant separated by the gas-liquid separator 5 reenters the refrigerant circuit for circulation, and thus, not only can the high-pressure refrigerant entering the vortex tube 6 keep in a gaseous state, but also the stable refrigerant circulation in the refrigerant circuit can be ensured by supplementing the separated liquid refrigerant to the refrigerant circuit.

In fig. 1, the cabinet air conditioning and heat dissipation system may further include a second check valve 92. The second check valve 92 is disposed on the refrigerant flow path between the liquid outlet 5c of the gas-liquid separator 5 and the outlet 22b of the second condenser 22, and is configured to be in one-way conduction from the liquid outlet 5c of the gas-liquid separator 5 to the outlet 22b of the second condenser 22.

By arranging the second check valve 92 on the refrigerant flow path between the liquid outlet 5c of the gas-liquid separator 5 and the outlet 22b of the second condenser 22, the liquid refrigerant in the refrigerant circuit is prevented from flowing back to the liquid outlet 5c of the gas-liquid separator 5 to affect the normal operation of the gas-liquid separator.

Referring to fig. 1, in some embodiments, the evaporator group 4 includes a first evaporator 41 and a second evaporator 42 connected in series, an outlet 41b of the first evaporator 41 communicates with an inlet 42a of the second evaporator 42, an outlet 42b of the second evaporator 42 communicates with the suction port 1b of the compressor 1, and an outlet 7b of the electrical box radiator 7 communicates with an outlet 41b of the first evaporator 41.

In this embodiment, the outlet 7b of the electric box radiator 7 is communicated with the outlet 41b of the first evaporator 41, so that the refrigerant discharged from the outlet 7b of the electric box radiator 7 reenters the refrigerant circuit to ensure stable refrigerant circulation in the refrigerant circuit; and the refrigerant discharged from the outlet 41b of the first evaporator 41 is merged and then secondarily evaporated through the second evaporator 42, thereby preventing the refrigerant of different temperatures outputted from different circuits from adversely affecting the function of the compressor 1 when entering the compressor 1.

In fig. 1, the cabinet air conditioner heat dissipation system further includes a third check valve 93. The third check valve 93 is provided on the refrigerant flow path between the outlet 7b of the electrical box radiator 7 and the outlet 41b of the first evaporator 41, and is configured to be one-way conductive from the outlet 7b of the electrical box radiator 7 to the outlet 41b of the first evaporator 41.

By arranging the third check valve 93 on the refrigerant flow path between the outlet 7b of the electric box radiator 7 and the outlet 41b of the first evaporator 41, the liquid refrigerant in the refrigerant loop is prevented from flowing back to the outlet 7b of the electric box radiator 7 to affect the normal operation of the electric box radiator 7.

Fig. 2 is a schematic diagram of signal connections in some embodiments of a cabinet air conditioning and heat dissipation system according to the present disclosure. Referring to fig. 1 and 2, in some embodiments, the cabinet air conditioner heat dissipation system further includes: a switching valve 94, a first temperature sensor 97, and a controller 96. A switching valve 94 is provided in the refrigerant flow path between the inlet 5a of the gas-liquid separator 5 and the condenser group 2. The switching valve 94 may include a solenoid valve, an electrically operated valve, a pilot operated valve, or the like.

A first temperature sensor 97 is located within the electrical box 8 and is configured to detect the temperature within the electrical box 8. The controller 96 is in signal connection with the switching valve 94 and the first temperature sensor 97, and is configured to send an on-off command to the switching valve 94 so as to turn on or off the switching valve 94.

The switching valve 94 is arranged on the refrigerant flow path between the inlet 5a of the gas-liquid separator 5 and the condenser group 2, the controller 96 can determine whether to turn on or off the switching valve 94 according to the temperature in the electric box 8 sensed by the first temperature sensor 97 in the electric box 8, and when the temperature in the electric box 8 is not high and the normal operation of components in the electric box 8 is not affected, the switching valve 94 can be turned off, so that the continuous and stable operation of the refrigerant circulation of the cabinet air conditioner is ensured.

When the temperature in the electric box 8 is higher to influence the normal operation of components in the electric box 8, the switching valve 94 can be conducted, the refrigerant in the condensing unit enters the vortex tube 6 through the gas-liquid separator 5, and the vortex tube 6 inputs the separated colder air flow into the electric box radiator 7 to realize the heat dissipation in the electric box 8, so that the temperature in the electric box 8 is reduced, and the normal operation of the components in the electric box 8 is ensured.

Referring to fig. 1 and 2, in some embodiments, the cabinet air conditioner heat dissipation system further includes: a first temperature sensor 97, a second temperature sensor 98, a proportional valve 95, and a controller 96. A first temperature sensor 97 is located within the electrical box 8 and is configured to detect a temperature T within the electrical box 8 _{Inner part} . A second temperature sensor 98 is located on the electrical box heat sink 7 and is configured to detect the temperature T of the electrical box heat sink 7 _{Powder medicine} . The proportional valve 95 is disposed on the refrigerant flow path between the cool air outlet 6b of the vortex tube 6 and the inlet 7a of the electric box radiator 7.

The controller 96 is in signal connection with the proportional valve 95, the first temperature sensor 97 and the second temperature sensor 98, and is configured to send a flow adjustment command to the proportional valve 95 so as to adjust the flow of the refrigerant entering the inlet 7a of the electric box radiator 7 from the cool air outlet 6b of the vortex tube 6.

The first temperature sensor 97 is arranged in the electric box 8, the second temperature sensor 98 is arranged on the electric box radiator 7, and the controller 96 can send a flow regulating instruction to the proportional valve 95 according to the difference value between the temperature in the electric box 8 and the temperature of the electric box radiator 7 on the refrigerant flow path between the cold air outlet 6b of the vortex tube 6 and the inlet 7a of the electric box radiator 7 so as to regulate the refrigerant flow entering the inlet 7a of the electric box radiator 7 from the cold air outlet 6b of the vortex tube 6, thereby not only ensuring the heat dissipation requirement of the electric box 8, but also avoiding the risk that the electric box 8 is exposed during heat dissipation to affect the electric safety.

For example, when the difference between the temperature in the electrical box 8 and the temperature of the electrical box radiator 7 exceeds the dew point temperature difference, the proportional valve 95 may be made to reduce the flow rate of the refrigerant entering the inlet 7a of the electrical box radiator 7 from the cool air outlet 6b of the vortex tube 6, so as to avoid the risk of condensation of the electrical box 8 during heat dissipation to affect electrical safety. For another example, when the difference between the temperature in the electrical box 8 and the temperature of the electrical box radiator 7 is lower than the dew point temperature difference, the proportional valve 95 is made to increase the flow rate of the refrigerant entering the inlet 7a of the electrical box radiator 7 from the cool air outlet 6b of the vortex tube 6, so as to ensure the heat dissipation requirement of the electrical box 8 and improve the heat dissipation efficiency.

The embodiments of the cabinet air conditioner heat dissipation system disclosed in the disclosure can be applied to the heat dissipation function of the electrical box of the cabinet air conditioner. Therefore, the embodiment of the present disclosure further provides a cabinet air conditioner, including: an electrical box 8 and a cabinet air conditioner heat dissipation system of any of the foregoing embodiments.

Referring to the embodiments of the cabinet air conditioner heat dissipation system and the control method thereof disclosed in the disclosure, since the electronic cabinet performs cooling and heat dissipation through cabinet air conditioner refrigeration throughout the year, if a set of independent refrigeration and heat dissipation system is additionally added on the basis of the cabinet air conditioner, space occupation can be increased, and space utilization rate is reduced. According to the embodiment of the cabinet air conditioner heat dissipation system, one path of refrigerant separated from the refrigerating system of the existing vehicle-mounted cabinet air conditioner can be input into the vortex tube, the characteristics of the vortex tube are utilized to provide cooling medium for the electric box radiator, effective heat dissipation of the electric box is ensured, the temperature stress coefficient is reduced, and the service life of components in the electric box is prolonged. Because the air conditioning system and the heat dissipation system share one set of refrigerant, the cooling system is not required to be additionally arranged, and the air conditioning space of the existing cabinet can be fully utilized, thereby fully utilizing the vehicle-carried limited space and improving the space utilization rate.

Taking the MOS microprocessor in the GJB/Z299C reliability prediction table 5.2.2-10 as an example, when the cabinet air conditioner heat dissipation system disclosed by the disclosure is adopted to dissipate heat of an electric box, the internal temperature of the electric box is reduced from 65 degrees to 61 degrees, and the temperature stress coefficient pi is reduced _T The reduction from 1.26 to 1.0 allows for an increase in the expected lifetime of the device by 26%.
