AI Technical Summary

Technical Problem

Existing cooling devices cannot simultaneously achieve rapid plugging and unplugging and effective heat dissipation during drone battery charging, resulting in inconvenient plugging and unplugging and reduced heat conduction efficiency.

Method used

An open-type immersion liquid cooling device is adopted, which realizes the recycling of coolant through a first liquid tank, a second liquid tank and a circulating heat dissipation component, ensuring that the cooled components are in full contact with the coolant for heat exchange, and the overflow structure maintains the coolant level to avoid frequent replenishment.

Benefits of technology

It enables rapid insertion and removal of drone batteries and efficient heat dissipation, reducing the frequency of manual coolant replenishment and improving the safety and efficiency of the charging process.

Abstract

The application discloses a liquid cooling device and a unmanned aerial vehicle battery charging system, which comprises a first liquid tank capable of accommodating a cooled part; a second liquid tank arranged to collect the cooling liquid overflowing from the first liquid tank; and a circulating heat dissipation assembly comprising a power pump and a radiator, wherein the input end of the power pump is connected with the second liquid tank, the output end of the power pump is connected with one end of the radiator, and the other end of the radiator is connected with the first liquid tank, so that the cooling liquid in the second liquid tank is pumped to the radiator for heat dissipation and then supplemented to the first liquid tank. The present application adopts an immersion liquid cooling mode, directly immerses the cooled part for cooling, and enables the surface of the cooled part to fully contact with the cooling liquid, so that efficient heat dissipation is realized. The cooled part does not need to be closely combined with the inner wall of the first liquid tank, and the quick insertion and extraction of the cooled part is facilitated. Meanwhile, the problem that the liquid level in the first liquid tank is lowered due to the cooling liquid brought out by the frequent insertion and extraction of the cooled part can be avoided, and the frequency of manually supplementing the cooling liquid for the liquid cooling device is effectively reduced.
