Radiator for power amplifier

The utility model discloses a heat radiator for a power amplifier, which comprises a rectangular heat radiation substrate; the heat dissipation fins are arranged on one side of the heat dissipation substrate and extend in the length direction of the heat dissipation substrate, and the heat dissipation fins are arranged in the width direction of the heat dissipation substrate at intervals and are parallel to one another; the surfaces of the two sides of each heat dissipation fin are in a symmetrical wave shape, a plurality of wave crests are formed on the surfaces of the wave shapes, the wave crests are sequentially arranged in the height direction away from the heat dissipation substrate, and the span of the wave crests is gradually reduced in the height direction away from the heat dissipation substrate. The radiator for the power amplifier provided by the utility model is relatively high in radiating efficiency. 本实用新型公开了一种功放用散热器，包含：散热基底，散热基底为矩形；若干散热翅片，若干散热翅片设置于散热基底的一侧且沿着散热基底的长度方向延伸，若干散热翅片在散热基底的宽度方向间隔排布且相互平行
