Capillary tube heat pipe and temperature controlling apparatus
First Claim
1. A capillary tube heat pipe having a heat receiving portion, a heat radiating portion and a heat transfer portion connecting said heat receiving portion and said heat radiating portion, the capillary tube heat pipe comprising:
- a capillary tube which forms a closed loop;
wherein the capillary tube has an inner diameter which is less than a maximum diameter which enables the working fluid to circulate in the capillary tube while being sealed inside the capillary tube;
wherein said heat transfer portion is constructed from only one pair of going and returning passages;
wherein the working fluid is capable of alternately flowing in a forward direction and a reverse direction within the capillary tube; and
wherein the heat receiving portion and heat radiating portion comprise a high heat conductive material, and the heat transfer portion comprises a low heat conductive material.

Abstract
A capillary tube heat pipe and the like are provided, in which is applicable for a case that a heat receiving portion is separated apart from a heat radiating portion, and a sufficient space for connecting the both portions does not exist. This capillary tube heat pipe (1) is provided with two turn portions (a heat receiving portion and a heat radiating portion) (3-1) and (3-2) at the both ends thereof and a straight portion (a heat transfer portion) (5) extending between the both turn portions (3), and has a closed loop structure in which both terminals of a single pipe are communicated. Since the heat transfer portion is made from two straight pipes (7) and (9), the straight portion (5) can be small in size.

16. A capillary tube heat pipe having a heat receiving portion, a heat radiating portion and a heat transfer portion connecting said heat receiving portion and said heat radiating portion, the capillary tube heat pipe comprising:
-
a capillary tube which forms a closed loop;
wherein said heat transfer portion is constructed from only one pair of going and returning passages;
wherein said heat receiving portion and/or said heat radiating portion comprises a meandering capillary tube (a meandering turn portion) having a plurality of turnings;
wherein said meandering turn portion is heated or cooled at one turn end side and is cooled or heated at another turn end side so as to cause a working fluid in said meandering turn portion to be evaporated and condensed, thereby increasing a flow force of the working fluid in said meandering turn portion;
wherein the working fluid is capable of alternately flowing in a forward direction and a reverse direction within the capillary tube; and
wherein the heat receiving portion and heat radiating portion comprise a high heat conductive material, and the heat transfer portion comprises a low heat conductive material. - View Dependent Claims (17, 18, 19, 23, 24, 25, 26, 27, 28)
