Abstract

PURPOSE: To make the inside and the outside of the inner cylinder which is mounted around the rotary shaft heat receiving chamber, and the heat transferring chamber with multi number of heat pipes with blade fins redially penetrated through the inner cylinder in multi stage to prevent deterioration in heat transferring effect by adhesion of the particles.

CONSTITUTION: The rotary shaft 3, which is fitted in the inner cylinder 5 through arms 4,4, is supported at the center of the cover plate la and the bottom plate 1b fixed on both ends of the outer cylinder 1. The top and the bottom ends of the inner cylinder 5 are slidably arranged around the outer peripherals of the short pipes 6a, 6b projected on both end parts to form the heat receiving chamber B and the heat transferring chamber A outside and inside of the inner cylinder. Eight heat pipes 7 are pentrated through theinner cylinder 5 rectangular to and radially mounted on the rotary shaft 3 horizontally and in multi stages vertically. The blade fins 7a, 7b are provided projected on the outer surfaces of the evaporating part and the condensing part of the heat pipes 7. By such constitution, the particles adhering to the heat pipes 7 are thrown away by the centrifugal force to prevent deterioration in the heat transferring effect.
