Problems solved by technology

Among them, the space occupied by the oil storage tank in the liquid cooling source is about half of the volume of the entire micro-hydraulic station. Therefore, the existing micro-hydraulic station is used for liquid-cooled charging guns and cables. The existing problems are as follows: the overall volume is large , Cannot be integrated inside the charging pile, high power consumption, poor cooling effect during the working process, the temperature of the coolant will continue to rise, and cannot effectively cool down the conductive terminals of the charging gun and the conductors of the cable, thus causing the charging system Less reliable for long working hours

Abstract

A liquid cooling source of secondary circulation cooling liquid comprises a cooling unit, a power unit, a case, a power supply and a control unit. According to the power unit, a motor drives a main pump and an auxiliary pump to work at the same time, the main pump drives the cooling liquid to circulate among the liquid cooling source, a liquid cooling charging gun and a cable, the auxiliary pump drives the cooling liquid to circulate and dissipate heat in the liquid cooling source for the second time, and the cooling liquid is fully cooled through the two circulations. According to the liquid cooling source of the secondary circulation cooling liquid, a traditional liquid storage tank structure is removed, a plurality of micro-channel radiators are arranged in the cooling unit, and the multiple micro-channel radiators and the cooling liquid stored in pipelines of a system are utilized, so that the liquid cooling source has the advantage of being small in size, and the liquid cooling source can be perfectly integrated in the charging pile; the micro-channel radiator arranged in the cooling unit has excellent heat dissipation performance, and the requirements of the charging pile for the volume, cooling efficiency, working energy consumption and working reliability of the liquid cooling source are fully met.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging piles, in particular to a liquid cooling source for a secondary circulating cooling liquid. Background technique [0002] Electric vehicles have developed rapidly due to the advantages of no exhaust emissions and no environmental pollution, and have become the future development direction of the automotive field. At present, there are two main factors restricting the development of electric vehicles: one is the short battery life; the other is the long charging time. The problem of short battery life needs to be solved by improving the energy density of lithium batteries through the development of lithium battery technology, but correspondingly, the charging time of lithium batteries is further extended. [0003] Using high-power fast charging can significantly reduce the charging time of lithium batteries, but excessive charging current will cause the conductive terminals and c...
