High-performance stable direct-current charging pile

Abstract

The invention relates to the technical field of charging piles, in particular to a high-performance stable direct-current charging pile which comprises a charging pile body. First fans are in threaded connection with the positions, close to the two ends, of the bottom of the inner wall of the charging pile body, a first heat dissipation bin is arranged at the top of the charging pile body, and a dustproof air inlet is formed in the right side of the first heat dissipation bin. A partition plate is arranged at the position, close to the dustproof air inlet, in the first heat dissipation bin, a fan is embedded in the middle of the side face of the partition plate, a dustproof air outlet is formed in the left side of the first heat dissipation bin, symmetrically-distributed rectangular mounting through grooves are formed in the position, close to the bottom, of the rear side of the charging pile body, and semiconductor chilling plates are arranged in the two rectangular mounting through grooves. According to the high-performance stable direct-current charging pile, the interior of the charging pile is cooled through the arranged first fan and the arranged semiconductor chilling plate, the temperature in the charging pile is prevented from being too high, and therefore what is ensured is that the charging pile can be in a high-performance charging state, the charging stability is maintained, and the situation of spontaneous combustion of the charging pile is avoided.

Description

technical field [0001] The invention relates to the technical field of charging piles, in particular to a high-performance stable DC charging pile. Background technique [0002] With the promotion and popularization of new energy electric vehicles, charging piles for charging electric vehicles are also being built on a large scale. In order to shorten the charging time of users, the existing charging piles generally adopt high voltage and high current working methods, but As the charging speed increases, the current and voltage will also increase linearly, which leads to an increase in the power of the inductance module of the charging pile, and the components such as the inductance module and the power module generate heat quickly and in large quantities. When the temperature inside the charging pile is high, It will affect the stability of charging, and there is a risk of spontaneous combustion. In view of this, we propose a high-performance stable DC charging pile. Cont...
