UV LED MODULE COOLING DEVICE

摘要

PURPOSE: A UV LED module cooling device is provided to improve cooling efficiency of a UV LED module by controlling the injection and discharge of refrigerant in a light emitting block. CONSTITUTION: A cooling block(110) receives heat from one or more light emitting devices. A first refrigerant line(120) supplies refrigerant to the cooling block. A second refrigerant line(130) compulsorily discharges refrigerant to the outside of the cooling block. The cooling block includes a receiver. The receiver includes a metal porous material(112) and an external block unit(111). The external block unit surround the metal porous material. A conduit line of an external block unit connects the first refrigerant line to the metal porous material.
