Ultrasonic probe having heat sink

Abstract

The present invention provides an ultrasonic probe which includes a heat sink ( 150 ) provided in a rear layer ( 140 ) to dissipate heat. The heat sink is coupled to a rear surface ( 141 ) of the rear layer such that contact area there between are increased. The heat sink includes a plurality of heat conductive protrusions ( 151 ) on one surface thereof. The heat conductive protrusions are inserted into respective heat conductive depressions ( 142 ) formed in the rear layer. Each heat conductive depression has a shape corresponding to the respective heat conductive protrusion. Preferably, each heat conductive protrusion has a bar shape.
