PROBLEM TO BE SOLVED: To provide a refrigerant piping unit, making a refrigerating apparatus compact-sized. SOLUTION: This refrigerant piping unit 25 is provided with a cooling part 14 for cooling an electric component 29 where a power semiconductor for controlling the constitutive devices of the refrigerating apparatus 10 is mounted. The electric component 29 is fitted to the cooling part 14. A cooling passage 20 communicated to a refrigerant passage 30 of a unit body 13 is formed in the cooling part 14. The electric component 29 is cooled by a refrigerant circulating through the cooling passage 20. COPYRIGHT: (C)2009,JPO&INPIT
