The traditional liquid cooling channel is a trough with the same width as the bottom. Not only is the amount of coolant passing through limited, but the contact surface between the coolant and the inside of the chassis is also limited. Utility Model Content

By setting the heat dissipation system of the precision instrument outside the chassis of the precision instrument and utilizing a closed liquid cooling channel with a wide mouth and a narrow bottom on the inner wall of the chassis, the throughput of the liquid cooling channel is increased and the channel mouth is widened to increase the cooling effect by utilizing the coolant in the channel to achieve the purpose of heat dissipation inside the chassis.

A trapezoidal upper cover with a narrow upper and wide lower structure whose bottom width is greater than the width of the liquid cooling groove opening is provided on the top of the cover strip. The cover strip is placed at the opening of the liquid cooling groove and can completely cover the liquid cooling groove. The two side walls of the cover strip are respectively in contact with the two side walls of the liquid cooling groove opening. The lower bottom surface of the trapezoidal upper cover protrudes from the two sides of the cover strip and rests on the two edges of the liquid cooling groove opening. After the cover strip covers the liquid cooling groove opening, the remaining liquid cooling groove forms a liquid cooling channel.
[0006] The large-flux liquid cooling channel of the hollow liquid cooling box plate is provided with liquid inlet and outlet holes penetrating the side wall of the plate at both ends of the liquid cooling groove.
