PROBLEM TO BE SOLVED: To provide a liquid-cooled type cooling device capable of reducing flow resistance which cooling liquid undergoes when flowing out of a casing.;SOLUTION: The liquid-cooled type cooling device is provided with a casing 2 having a cooling-liquid inlet and a cooling-liquid outlet 27, and an outflow pipe 7 connected to the cooling-liquid outlet 27. The casing 2 is provided with a cooling-liquid outflow portion 14 and the cooling-liquid outlet 27 is formed in a top wall 21 of the cooling-liquid outflow portion 14. The outflow pipe 7 has a lower wall 7a parallel to a portion of the top wall 21 of the cooling-liquid outflow portion 14 where the cooling-liquid outlet 27 is formed. A through-hole 47 connected to the cooling-liquid outlet 27 is formed to the lower wall 7a of the outflow pipe 7. A guide portion 40 is provided on a portion of an upper surface of a bottom wall 22 of the cooling-liquid outflow portion 14, the portion corresponding to the cooling-liquid outlet 27, so as to change, toward an upward direction, the flow direction of the cooling liquid flowing into the cooling-liquid outflow portion 14.;COPYRIGHT: (C)2009,JPO&INPIT
