Abstract

Provided is a DC charging pile air-cooling circulation system. The invention discloses a DC charging pile air-cooling heat dissipation system which solves the problem that an existing device is low inefficiency and high in consumption. The system includes an air-cooling heat dissipation module which is used for conveying cooling air to perform heat exchange with a heat-generating device and discharging hot air, thereby cooling a DC charging pile; the system can be divided into a duct, a gear-toothed heat pipe combined radiator and a fan; the duct is used for conveying cooling air to cool a power device and discharging hot air; the gear-toothed heat pipe combined radiator includes a gear-toothed radiator, an embedded heat pipe and a liquid metal heat-conducting fin and is used for conducting heat of the power device out to perform heat exchange with the cooling air; and the fan is used for sucking the cooling air from the outside of the system to make the cooling air flow in the duct.The system can effectively improve the comprehensive convective heat exchange capacity of the air cooling, and the air cooling effect is more obvious, ensuring that the heat generated inside the DC charging pile is effectively and timely discharged.

Description

technical field [0001] The present application relates to the technical field of electric vehicle charging equipment, in particular to an air-cooled circulation system of a DC charging pile. Background technique [0002] DC charging pile is a kind of charging equipment to realize high-power and fast charging of electric vehicles. The power charging module that converts AC to DC is the core component and the main heat source. High temperature will have a serious impact on most components. The performance of the device changes or even fails, resulting in the failure of the entire DC charging pile. Electric vehicle users have higher requirements on the charging time of charging piles. High power density is the development trend of DC charging piles. High power and small volume will inevitably lead to more concentrated heat and greater resistance to heat transfer. How to timely and effectively reduce the heat generated by power devices It is an urgent problem to be solved to en...
