WARM FLUID CIRCULATING MACHINE

摘要

PROBLEM TO BE SOLVED: To reduce the number of piping such as an intake pipe, improve power efficiency of a system by preferably applying heat releasing energy of a non-contact switching unit such as an electric motor and a triac so as to eliminate a coolant for the non-contact switching unit like the triac. SOLUTION: An intake port 11 of an electric pump is directly connected to a tank outlet 21 formed at the lower portion of a reserve tank 20. A casing 12 and the reserve tank 20 are formed into an integrated body by making a wall 23 common to a part of the casing 12 of the electric pump 10 and a part of the reserve tank 20. The integrated body is formed of the material exhibiting high heat conductivity like bronze. A flat heater 31 is mounted on the outer wall of the reserve tank. A triac 34 and a thermistor 35 are mounted on the outer wall of the casing 12. Therefore, the electric motor and the triac 34 can be cooled well irrespective of warm fluid.
