Cooler uses low-viscosity hydraulic powered systems with oil to cool down the temperature to the target temperature. TQ family coolers are assembled by front cover, back cover, main body and cooling core. The cooling core is made by heat pipe, fixed plates, movable plates, spoiler and rod. In order to avoid problems caused by thermal expansion, the heat pipe is made by special cooper wing chips with one end fixed and the other end movable. Cooling core is able to remove from the body for check, clean and maintenance. Water chamber is capable of installing Zinc bars in order to avoid corrosion and extend the maintenance cycle and life.
