PURPOSE: A heat exchange unit is provided to improve the adhesive property between a heat exchanger and an insulating resin layer by preventing the damage and cracking of the insulating resin layer. CONSTITUTION: A heat exchange unit includes a thermoelectric module and a heat exchanger(11). The thermoelectric module comprises an upper electrode, a lower electrode(13), and a plurality of thermoelectric elements. A plurality of thermoelectric elements are interposed between the upper electrode and the lower electrode. The heat exchanger is made of an aluminum alloy layer or aluminum which has high thermal conductivity. The heat exchanger is attached to the upper electrode and/or the lower electrode through an insulating layer(12). The surface roughness of the heat exchanger which is connected to the insulating layer is controlled to range from 0.1um to 4.7um. |
