Abstract
A scroll fluid machine has a fixed scroll in a housing and an orbiting scroll rotatably mounted to a driving shaft. A fixed wrap of the fixed scroll is engaged with an orbiting wrap of the orbiting scroll. The orbiting scroll is revolved at a certain eccentricity by the driving shaft, so that a gas sucked through the circumference of the housing is compressed as it moves toward the center, and discharged through the center. A gas-guiding bore is formed near the center of the orbiting scroll, and a heat-releasing rod is inserted in the bore. One end of the heat-releasing rod is projected from the fixed scroll to release heat to atmosphere.

A scroll fluid machine comprising:
- a housing;
- a driving shaft having an eccentric axial portion;
- a fixed scroll having a fixed wrap in the housing;
- an orbiting scroll rotatably mounted to the eccentric axial portion of the driving shaft, having an orbiting wrap, said orbiting scroll being revolved at a certain eccentricity by the driving shaft so that a gas sucked through a circumference of the housing being compressed as it moves toward a center of the orbiting scroll and discharged;
- and a gas-guiding bore formed axially near a center of the orbiting scroll, air being passed through the gas-guiding bore thereby releasing heat generated near the center of the orbiting scroll.
