Working principle of the heat pipe radiator heat pipe radiator is running, the evaporator absorbs heat source (power semiconductor devices, etc.) produced by the heat, the liquid core tube into the liquid boiling heat pipe radiator with the heat of steam from the steam evaporation cooling segment to its mobile, when pass after cooling section, the heat steam condensing liquid and steam is condensed into liquid through the pipe wall on the capillary action of liquid core returns to the absorption evaporation section, repeat the cycle continuously cooling heat pipe radiatorHeat pipe radiator of the heat pipe has the advantage that the heat transfer fast, install to radiator can effectively reduce the thermal resistance, increase the cooling efficiency, has the high thermal conductivity, high thermal conductivity of pure copper ability is one hundred times, have good heat pipe heat superconducting laudatory name process pass design CPU radiator, will be out of reach for ordinary without heat pipe air cooled radiator strong performance in the current CPU radiator, the vast majority of heat pipe technology has been adopted the heat transfer efficiency of heat pipe and diameter structure technology, currently in good use 6 mm more heat pipe in heat pipe radiator, also have individual with 8 mm productA certain research institute has given a group of reference values. Heat pipes with a diameter of 3mm can only transfer 15W of heat in 2.8 standard heat transfer cycles, while heat pipes with a diameter of 5mm can transfer 45W of heat in 1.8 heat transfer cycles, which is 3 times as much as 3mm heat pipe!And only 0.6 to 8 mm tube product cycles can deliver up to 80 w heat so high heat transmission, if you don't have good heat sink design and fan to cooperate, it is easy to cause heat to radiate heat pipe radiator in civilian electronic products, computer application in aspects of CPU card is only a small unit, its application in power electronics industry is also widely, such as new energy power supply industry, IGBT SVG can be used on high power devices such as heat pipe radiator for cooling
