PURPOSE: A heat radiation structure is provided to obtain a compact register, while achieving improved heat radiation efficiency and reducing pressure loss and noise. CONSTITUTION: A heat radiation structure comprises a substrate(1) a corrugated radiation fin(5) installed to the substrate; and a plurality of louvers(51) arranged in a lengthwise or widthwise direction at a side of the substrate. The heat generated from a serial resistance circuit(2) is transferred to the radiation fin, and the air passing through the substrate and the corrugated radiation fin flows through the louvers, to thereby enhance heat radiation efficiency.
