摘要
A cooling block 17 has three water channels 21 formed so as to be located near an LD device 18 fixed to a side surface 17c, each water channel 21 having a water channel sectional shape like an elongated hole, and being inclined relative to the side surface 17c. Heat generated by the LD device 18 is eliminated by cooling water flowing through the water channels 21. The water channel sectional area of an inlet manifold water channel is rendered not less than twice the water channel sectional area of the cooling block water channel. Irregularities are formed on the inner surface of each of the cooling block water channels. Further, an inlet portion of the cooling block water channel is chamfered or given a curvature.
