PIPING DEVICE, AND FLUID CARRYING DEVICE

摘要

Provided is a piping device, which can heat a fluid carrying pipe (40) efficiently thereby to improve the homogeneity of the temperature of the fluid to flow in the pipe (40). The piping device includes the pipe (40) and a heating portion disposed at the end portion of the pipe (40) for heating the pipe (40). Inside of the annular wall of the pipe (40), there are disposed a plurality of tubes (42) along the extending direction of the pipe (40), a connecting pipe (43) for connecting the one-side ends of the tubes (42) to each other, and a connecting pipe (44) for connecting the other ends of the tubes (42) to each other. The tubes (42), the connecting pipe (43) and the connecting pipe (44) constitute a looped thin heat pipe (30).
