Overall cooling charging device for electrical vehicle

The invention provides an overall cooling charging device for an electrical vehicle. The overall cooling charging device comprises a power supply side connector (100) and a vehicle side connector (200), and the power supply side connector (100) is connected with a charging cable (300) and comprises a first box (101) which comprises a magnetic coupling convex part (111), a first iron core vertical plate side cooling part (110) and a first coupling end face (112); the vehicle side connector comprises a second box (201) which comprises a magnetic coupling concave part (211), a circumferential cooling part (209), a second iron core vertical plate side cooling part (210) and a second coupling end face (212); the charging cable (300) comprises a cable core (302) and a cable cooling water channel (301) surrounding the periphery of the cable core; water entry of the cable cooling water channel (301) is communicated with that of the first iron core vertical plate side cooling part (110); the power supply side connector (100) is suitable for forming end face coupling while forming electromagnetic coupling with the vehicle side connector. The overall cooling charging device communicates the cable, the power supply side connector and the vehicle side connector into the overall cooling channel, and control over working temperature of the charging device is greatly enhanced.

Active two-phase loop and phase change heat storage compound thermal control system

InactiveCN106954373AGood temperature control characteristicsLow circulation flow of working fluidModifications using liquid coolingTemperature controlLiquid line
The invention provides an active two-phase loop and phase change heat storage compound thermal control system, which belongs to the technical field of heat radiation and cooling. The system mainly comprises a heat absorber, a reservoir, a condenser, a steam line, a drive device, a liquid line and a blower fan. The heat absorber is of an integrated structure which is formed by packaging a head conducting housing, an evaporation chamber, a heat storage material and fins. The outlet of the evaporation chamber is communicated with the inlet of the condenser through the steam line, and the outlet of the condenser is connected with the reservoir and the drive device in sequence through the liquid line, and finally accesses to the inlet of the evaporation chamber, so as to form an enclosed loop. When the calorific value is small, heat can be absorbed by the heat storage material and radiated through the fins, so as to limit or delay the temperature rise; when the calorific value is larger, the drive device is started to operate the active two-phase loop. Specifically, when the heat changes dynamically or in a pulsed manner, the system maintains the good temperature control of the electronic chip or equipment, and has advantages of strong heat dissipation capacity, compact structure, safe temperature control, strong applicability, wide application range and the like.
