AI Technical Summary
In traditional liquid cooling devices, uneven coolant flow leads to increased flow resistance, affecting heat dissipation efficiency. Furthermore, the reduced volume of coolant further impacts flow rate and volume.
Design a liquid cooling device comprising a base, a flow guide shroud and a base. By setting a set of recesses, grooves and return channels in the flow guide shroud, an inlet chamber and a distribution space are formed. The coolant is first temporarily stored in the inlet chamber and then flows evenly into the distribution space and flow channel, thereby improving the flow rate and heat exchange efficiency.
It achieves uniform flow of coolant, improves flow rate and heat exchange efficiency, ensures that coolant can effectively dissipate heat, and meets the needs of thin-film design.
