AI Technical Summary
In existing liquid-cooled radiators, the temperature of the coolant gradually increases in the strip-shaped flow channel, resulting in a gradual decrease and uneven heat dissipation capacity.
Design a liquid-cooled radiator with a reciprocating flow channel, in which the coolant flows back and forth between the first channel, the cooling channel and the second channel. The first channel and the second channel are formed in a wave shape to achieve the alternating distribution of hot and cold coolant.
It improves the temperature uniformity of the coolant, increases the heat dissipation uniformity and cooling efficiency of the objects to be cooled, and is suitable for cooling multiple objects.
