Title:
HEAT TRANSPORTING DEVICE
Document Type and Number:
Japanese Patent JP3306480
Kind Code:
B2
Abstract:
PURPOSE: To eliminate a clogging at a filter and prevent an amount of circulation with a pump from being lowered by a method wherein a suction pipe of a bypassing pipe and a filter covering an injection pipe are rotated to separate adhered particles.
CONSTITUTION: At a stage in which mixed liquid in a circulating pipe 2 is circulated, the liquid receives heat at a heat receiving side heat exchanger 1b and the heat is radiated at a heat radiating side heat exchanger 1a. Liquid 32 contained in the mixed liquid passes through a filter 7 in the midway of the circulation passage, the liquid is sucked through the suction pipe 4 under an operation of a pump 5, passes through a bypassing pipe 24 and then is returned back again into the circulating pipe 2 from the injecting pipe 6. At that time, the filter 7 clogged with particles 3 at the suction pipe 4 is rotated together with a easing 25, thereby the filter is moved toward the injection pipe 6 and then the particles 3 are blown off with discharging pressure of the liquid 32 injected from the injection pipe 6. The liquid 32 returned back into the injection pipe 2 is circulated while giving an energy to the particles 3 around it. A rotating power of the casing 25 is given by applying a kinetic energy of the liquid 32 to a vane 8.
