Description

Technical Field

[0001] The utility model belongs to the technical field of charging pile heat dissipation, and particularly relates to a liquid cooling mechanism for an ultra-high voltage charging pile. Background Technique

[0002] As a charging device for new energy vehicles, a charging pile can be analogously understood as an oil and gas fuel dispenser for conventional fuel vehicles. Charging piles are usually installed in public construction sites, parking lots or roadsides in residential communities. Charging piles are divided into AC charging piles and DC charging piles according to the output current method. Currently, DC charging piles are used more frequently. A DC charging pile outputs DC electric energy to the vehicle. The external end of the DC charging pile equipment introduces commercial power (three-phase power), and the alternating current is rectified inside the charging pile (AC-DC conversion). Then, through the monitoring of the control center and the coordinated work of each component, the pile body transmits direct current with a specified size and power to the vehicle battery.

[0003] After retrieval, the patent publication number CN220947615U discloses a liquid cooling and heat dissipation structure for a charging pile, belonging to the technical field of charging pile heat dissipation. Aiming at the problem that the existing liquid cooling and heat dissipation structure for a charging pile lacks a heat dissipation structure that can promote the rotation of the fan blades by means of the flow power of the coolant during use, which increases the use cost of the electric drive structure. It includes a charging pile housing and a charging core device. The front and rear side walls of the charging core device are fixedly connected to the inside of the charging pile housing through two connecting plates. Filter nets are fixedly connected to the air inlet openings on both side walls of the charging pile housing, and a base is fixedly connected to the bottom end of the charging pile housing. In the utility model, through the arranged liquid cooling component, when the liquid pump is started, the preset coolant in the cavity is extracted, and then it flows through the conveying pipe to a plurality of coolant circulation pipes. And with the action of a plurality of heat conducting plates, the heat generated when the charging core device works can be transferred through the coolant flowing in the plurality of coolant circulation pipes.

[0004] When the existing liquid cooling mechanism for an ultra-high voltage charging pile is actually used, due to the high temperature inside the ultra-high voltage charging pile, when the liquid cooling mechanism cools the charging core components inside the ultra-high voltage charging pile by liquid cooling, due to the large temperature difference between the liquid cooling mechanism and the charging core components, condensed water will be generated on the outer wall of the liquid cooling mechanism. When the condensed water falls on the charging core components, it is easy to cause the charging core components to be corroded or even damaged by the condensed water, and the service life is reduced. Therefore, we propose a liquid cooling mechanism for an ultra-high voltage charging pile to solve the existing problems. Content of the Utility Model
