A WATER BLOCK is the water cooling equivalent of a heatsink. The surface of the 40MMX40MM WATER COOLING BLOCK is polished, the inner flow channel is extruded into an M-shaped flow channel, brazing parts into a whole. A WATER BLOCK is better at dissipating heat than an air-cooled heatsink due to water’s higher specific heat capacity and thermal conductivity. Aluminium Water Block is Used widely in computer CPU, graphics GPU heat, Xbox consoles CPU, semiconductor cooling piece, industrial inverter driver, laser head cooling, and industrial control cabinet cooling.WATER COOLING HEATSINK is tailor-made for semiconductor refrigerating tablets and can be used for heat dissipation, cold transfer, cold water formation, etc.
