It should be noted that the second cooling line 50 can also be used to cool the terminal 11 and/or the housing 14 , that is, the second cooling line 50 can be used for the terminal 11 , the charging line 12 and the housing. At least one of 14. The following description continues with the second cooling duct 50 cooling the charging harness as an example.

Wherein, the second cooling line 50 may be disposed only on one of the housing 14, the terminal 11 or the charging harness 12; the second cooling line 50 may be simultaneously disposed on the housing 14 and the terminal 11, and simultaneously set The housing 14 and the charging harness 12 are simultaneously disposed on the terminal 11 and the charging harness 12; the second cooling duct 50 can be simultaneously disposed on the housing 14, the terminal 11 and the charging harness 12.

The air conditioning cooling system 20 may include: a compressor 21 connected in series, a condenser 22, a valve body 29, and an evaporator 23, that is, the compressor 21, the condenser 22, the valve body 29, and the evaporator 23 are connected in series, A flow passage 74 is provided on the bulkhead of the cooling compartment 70, and the flow passage 74 is configured as at least a portion of the evaporator 23. It will also be appreciated that both the flow passage 74 and the evaporator 23 are disposed within the cooling compartment 70, and the evaporator 23 is coupled to the cooling compartment 70 via the flow passage 74. Thereby, the evaporator 23 disposed in the cooling compartment 70 can exchange heat with the charging connector 10 at the cooling compartment 70, and the cooling compartment 70 thus provided can ensure the rationality of the arrangement of the evaporator 23 and the charging connector 10, and The operating temperature of the charging connector 10 can be effectively reduced, and the problem of overheating of the terminal 11 can be avoided.

As shown in FIGS. 8 and 9, the cooling compartment 70 includes a front fixing seat 71 and a rear fixing seat 72, and the evaporator 23 is disposed between the front fixing seat 71 and the rear fixing seat 72. Under isostatic conditions, the evaporator 23 boils the low-temperature low-pressure refrigerant vapor coming from the capillary 27, absorbing the heat of the charging connector 10, and becomes a low-temperature low-pressure refrigerant dry saturated steam. The front mount 71 is connected to the rear mount 72, and the front mount 71 and the rear mount 72 are provided with mounting holes for mounting the charging connector 10. Further, the flow path 74 is disposed in the rear fixed seat 72, and the liquid inlet and the liquid outlet of the flow path 74 penetrate the rear fixed seat 72. That is to say, the charging connector 10 can be mounted on the front fixing seat 71 and the rear fixing seat 72 at the same time, so that the mounting reliability of the charging connector 10 can be ensured on the one hand, and a part of the charging connector 10 can be cooled on the other hand. The interior of the compartment 70, so that the charging connector 10 can be wrapped by the cold air in the cooling compartment 70, can enhance the heat exchange effect of the evaporator 23 and the charging connector 10, thereby further reducing the operating temperature of the charging connector 10.

The cold air can flow into the cooling chamber 70 through the air cooling passage 73, and then the cold air flowing into the cooling chamber 70 contacts the charging connector 10 through the vent hole, so that the cooling connector 10 can be cooled.

In a specific embodiment, as shown in FIGS. 7-9, the air conditioning cooling system 20 may further include: a blower 25 disposed in the air cooling passage 73, and an outlet and cooling of the air cooling passage 73. Cabin 70 is connected. The air blowing member 25 can supply air to the cooling compartment 70. The arrangement of the air supply member 25 can increase the heat exchange efficiency of the evaporator 23 and the charging connector 10, so that the speed of lowering the temperature of the charging connector 10 can be accelerated, and the charging connector 10 can be maintained within a suitable operating temperature range. The air blowing member 25 may be an axial fan. The axial flow fan can facilitate the air supply to the interior of the cooling compartment 70, and the axial flow fan has a simple structure.

That is, the cold air blown into the cooling compartment 70 by the air blowing member 25 can be blown out from the air outlet 71c, so that the cold air blown out can be brought into contact with the charging connector 10 again, so that the heat of the charging connector 10 can be better taken away.

As shown in FIG. 10, the charging connector 10 may include a housing 14 and a terminal 11 fixed in the housing 14, and a vent hole 15 is formed in an inner circumference of the housing 14. Therefore, when the charging connector 10 is docked with the charging gun, the cold air enters the cooling compartment 70 through the air inlet 71d, and then the cold air flows out from the air outlet 71c, and then the cold air blown from the air outlet 71c can flow through the air vent 15 to connect the charging. The piece 10 is wrapped so that the cold air can not only cool the charging connector 10, but also cool the charging gun, so that the operating temperature of the charging connector 10 can be better reduced.

The vehicle 1000 controls the operation of the blower 25 when charging, and is adapted to control the operation of the compressor 21 when the temperature value detected by the temperature sensor is greater than a predetermined value. That is to say, the air blowing member 25 and the compressor 21 can operate at different times. For example, when the temperature is low and the charging connector 10 is just beginning to be charged, the air blowing member 25 starts to operate, and the charging connector 10 can be supplied with a certain flow rate. The normal temperature wind can slow down the operating temperature of the charging connector 10, and when the temperature of the charging connector 10 rises to a predetermined temperature, the compressor 21 starts to work again, and the evaporator 23 first exchanges heat with the air, and the air is recharged. The connector 10 exchanges heat so that the operating temperature of the charging connector 10 can be quickly reduced.

The charging device 100 may further include: a controller for detecting the temperature of the charging connector 10, and a temperature sensor electrically connected to the controller, the controller being adapted to detect the vehicle at the charging state detecting module The 1000 blower 25 is controlled to operate while charging, and is adapted to control the operation of the compressor 21 when the temperature value detected by the temperature sensor is greater than a predetermined value. That is to say, the air blowing member 25 and the compressor 21 can operate at different times. For example, when the temperature is low and the charging connector 10 is just beginning to be charged, the air blowing member 25 starts to operate, and the charging connector 10 can be supplied with a certain flow rate. The cold air can ensure the operating temperature of the charging connector 10, and when the temperature of the charging connector 10 rises to a predetermined temperature, the compressor 21 starts to work again, and the refrigerant in the evaporator 23 and the charging connector 10 exchange heat again. Thereby, the operating temperature of the charging connector 10 can be quickly lowered.

It should be noted that the cooling systems 20 of the above various embodiments may be combined with each other without interference. For example, two types of cooling systems 20 are employed in FIG. 1, and, for example, the cooling system 20 and the diagrams in FIG. The cooling system 20 in 6 can be combined.
