Liquid Cooling Apparatus for Heat Dissipation of High Power Light Emitting Diode

It provides a liquid cooling system for the heat generated by the high-power LED. The present invention is an LED mounted on the substrate at least one LED module for generating the power is on, the light; The LED module is at least one which is provided with heat transfer surfaces to be mounted, and, equipped with a jacket body that forms a circulation flow flowing through the cooling fluid to the interior space enclosed by the heat transfer surfaces the heat exchange column is passed through said transfer surface cooling fluid filled cooling jacket; An external heat sink to connect the connection line and the cooling jacket as a medium and the cooling fluid is circulated to be discharged from the cooling jacket; It includes; and is provided between the external heat sink the cooling jacket and the piezoelectric pump for forcibly circulating the cooling fluid to the outside as the radiator circulating within the heat exchanger cooling fluid is supplied to the cooling jacket. According to the present invention, exhaust waste heat generated from the LED module light source efficiently to the outside from the light source to prevent overheating of the light source, it is possible to increase the cooling efficiency. LED, liquid cooling, the heat transfer surfaces, a cooling jacket, a piezoelectric pump, an external heat sink, heat
