Abstract

The invention discloses a charging gun heat exchange structure and a charging gun. The charging gun heat exchange structure comprises a heat exchange groove formed in the charging gun head; the heat exchange groove is connected with a liquid inlet pipe and a liquid outlet pipe; main wire terminals and a ground wire terminal pass through the heat exchange groove; a coolant which flows from the liquid inlet pipe flows through the heat exchange groove to perform heat exchange with the main wire terminals and then flows out of the liquid outlet pipe; the main wire terminals are set to be electrically isolated from the coolant in the heat exchange groove; and the ground wire terminal is set to be in electrical contact with the coolant in the heat exchange groove. By adoption of the charging gun heat exchange structure, the risk hidden danger caused by coolant leakage can be greatly lowered.

Description

technical field [0001] The invention relates to a heat exchange structure of a charging gun and a charging gun with the heat exchange structure. Background technique [0002] The cooling tube is arranged in the charging gun, and the terminal can be cooled by the liquid in the tube. The usual structure is to make a heat exchange tank, use a refrigeration tube to continuously provide refrigeration liquid to the heat exchange tank, and place the terminals outside the heat exchange tank to reduce the terminal temperature. [0003] Since the liquid pump that provides power to the coolant usually has a metal casing, and the metal casing will be grounded, once the heat exchange tank leaks liquid and the coolant comes into contact with the main line terminal, since the coolant is a conductive liquid, it will generate from Short circuit between the main line of high voltage and the ground of the metal casing of the liquid pump. The short circuit includes the main line conductor, th...
