Abstract

The refrigerator of the present invention includes: an inner shell for forming a storage room; a thermoelectric module for cooling the storage room, including a thermoelectric element and a radiator in contact with the thermoelectric element; a fixing pin fixed to the radiator and a heat dissipation fan provided with a fixing pin through hole through which the fixing pin penetrates, and is spaced from the heat sink in a state of being coupled with the fixing pin.

Description

technical field [0001] The present invention relates to a refrigerator, and more specifically, to a refrigerator using a thermoelectric module to cool a storage room. Background technique [0002] A refrigerator is a device used to cool or store food or medicine at a low temperature to prevent them from spoiling or deteriorating. [0003] A refrigerator includes a storage compartment for storing food or medicine, etc., and a cooling device for cooling the storage compartment. [0004] As an example of the cooling device, it may be constituted by a refrigeration cycle device including a compressor, a condenser, an expansion mechanism, and an evaporator. [0005] As another example of the cooling device, it may be composed of a thermoelectric module (TEM: Thermoelectric Module) that combines different metals and utilizes a phenomenon that causes a temperature difference between both end surfaces of the different metals when a current is applied thereto. [0006] A refrigerat...
