LOOP HEAT PIPE

摘要

PROBLEM TO BE SOLVED: To provide a loop heat pipe of high performance provided with an evaporating part or a condensing part with low heat resistance and low passage resistance and stably circulating an operating fluid in a fixed direction in a closed loop while completely preventing the contraflow of steam. SOLUTION: This loop heat pipe comprises: a condensing part formed of a plurality of parallel-connected passages thermally connected to a cooling means; an evaporating part thermally connected to a cooled body; a steam passage communicating the evaporating part with the condensing part and allowing steam to flow inside; a condensate passage communicating the condensing part with the evaporating part and allowing condensate to flow inside; an operating fluid filled inside; and a contraflow preventing mechanism making it easy for the operating fluid to flow in one direction.
