| 摘要 |
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.
