Abstract

The present invention provides a piping unit that facilitates downsizing of a cooler by decreasing the temperature of fluid to be introduced into the cooler without reducing the cooling effect of a cooler. A piping unit is for introduction of heated fluid into a cooler, the piping unit being formed from synthetic resin and including a heat exchange structure on an inner peripheral surface.

Claims

1. A piping unit for introduction of heated fluid, wherein the piping unit is formed from synthetic resin and comprises a heat exchange structure at least on an inner peripheral surface.

2. The piping unit according to claim 1, wherein the heat exchange structure is an asperity geometry formed at least on the inner peripheral surface of the piping unit.

3. The piping unit according to claim 1, wherein the heat exchange structure is a rib erected at least on the inner peripheral surface of the piping unit.

4. The piping unit according to claim 1, wherein the piping unit is constructed of a combination of at least a first segment and a second segment.

5. The piping unit according to claim 1, wherein the piping unit comprises a bent portion.

6. The piping unit according to claim 1, wherein the fluid is compressed and heated by a supercharger.
