PURPOSE: A cooling apparatus for headlight dehumidification is provided to improve a dehumidification effect by arranging a plurality of pins for the expansion of an air contact area. CONSTITUTION: A cold block(110) is made of a material having an excellent heat transfer coefficient on an upper side of a thermoelectric module(120). A plurality of upstanding fins is formed on the top of the cold block. The thermoelectric module is installed between a bottom surface of the cold block and the upper side of a radiating unit. The thermoelectric module is formed into a two-stage in which a top thermoelectric module(120a) and a lower thermoelectric module(120b) adhesively arranged on the bottom surface of the top thermoelectric module are laminated. A radiating unit(130) is installed to the bottom surface of the thermoelectric module. A cooling fan(140) is located to improve heat dissipation efficiency on the bottom surface of the radiating unit. |
