Abstract

PURPOSE:To improve the cooling efficiency of a cone by providing a cooling fin on the cone outer peripheral face in the power dumper equipped with the cone to absorb a laser light and the housing to store it and to cool the cone with the cooling water communicating the inner part. CONSTITUTION:Plural cooling fins 6 whose outer peripheral edges are closely fitting to the inner peripheral face of a housing 3 at the prescribed intervals in the axial direction are provided on the outer peripheral face of the cone 1 in a funnel shape of the lower end closed. An opening 7 is alternately provided at the peripheral edge part opposing to the diameter direction on each cooling fin 6. The bending path of the cooling water is then formed inside the housing 3 by these each cooling fin 6. In this power dumper, a laser light 5 is led by the cone 1, absorbed as a heat energy and this heat energy is disposed by being transmitted to the cooling water communicating inside the housing 3. Since the contact area of the cone 1 and cooling water is increased by the cooling fin 6 in this case the cooling efficiency of the cone 1 by the cooling water is made better and can be used as for high output.
