な（対流放熱させることが可能である。[Prior Art] A check valve is disposed at a predetermined portion within a tight loop type capillary container in which both ends of a long thin tube are connected to each other, and a predetermined portion on the loop is connected to a heat receiving part. JP-A No. 63-31849 discloses a loop-type capillary heat vibrator in which another predetermined portion is configured as a heat dissipation section and a predetermined amount of two-phase condensable working fluid is enclosed in a loop-type capillary container.
No. 3 is described in detail in U.S. Pat. No. 4,921,041. The thin tube heat pipe ensures that the working fluid moves in a predetermined direction within the loop due to the interaction between the check valve and the temperature difference between the heat receiving and dissipating parts, without the need for any kind of seed or electric circulation means. It circulated strongly and transported heat from the heat receiving part to the heat radiating part. This circulation of the working fluid is reliable regardless of the arrangement position of the thin tube heat pipe, i.e., in bottom heat mode, horizontal heat mode, or top heat mode, and is unconventional for conventional heat pipes as a means of transporting heat. It was designed to perform functions that were previously unavailable. In the loop type thin tube heat pipe, as illustrated in the schematic diagram of FIG. 3, the thin tube container 1 repeats meandering through many turns, and each of the thin tube containers has a heat receiving section 1-1. Heat radiation part 1-2. It has generally been used to form a heat insulating section (connecting section) 1-3. 2 to 1.2-2 are check valves, and 3 and 4 indicated by broken lines are heating means and cooling means, respectively. The thin tube containers are all shown in line diagrams in the following figures to simplify the drawings. The arrow indicates the direction of hydraulic fluid circulation. The working fluid, which naturally circulates in the direction of the arrow in the loop-shaped capillary 1, suffers a large pressure loss within the capillary, but the heat received at each turn gives it a new driving force due to nucleate boiling, and it is revived, as shown in Figure 3. The loop-type capillary heat pipe can increase the number of turns without limit and can transport a large amount of heat. Also φ2IllI1
1. Since it can be constructed with a thin tube container such as φ3m+m, the amount of heat generated in a narrow part can be transported through a narrow gap. In addition, since the multi-tube heat radiating section 1-2, which is constituted by a group of straight pipes of such a thin tube container, can obtain an extremely high heat transfer coefficient, it is possible to radiate heat by convection without installing a group of fins.

為に特願平２−１４８８０９号に詳述されてある如きル
ープ型細管ヒートパイプが案出された。As for the above-mentioned loop-type thin tube heat pipe, there is a stronger demand for a small number of straight pipe sections of the thin tube container that constitute the heat insulating section (connecting section) l-3 that connects the heat receiving section 1-1 and the heat dissipating section 1-2. It was requested that it be made into a book. In other words, when the heat receiving part 1-1 and the heat dissipating part 1-2 need to be connected through an extremely complicated and narrow gap between the parts, the number of straight pipe parts of the thin tube container in the heat insulating part (connection part) 1-3 should be as small as possible. It is desirable that the number of Furthermore, if the distance between the heat receiving section 51-1 and the heat dissipating section 1-2 is long, handling of the large number of straight pipe sections may become complicated and difficult. In order to solve these problems, a loop-type thin tube heat pipe was devised as detailed in Japanese Patent Application No. 148809/1999.

あった。FIG. 4 is a schematic diagram of the basic structure of such a loop-type capillary heat pipe with separate heat receiving and dissipating parts. The heat receiving section 1-1 and the heat dissipating section 1-2 are each made elongated by meandering multiple turns, and are separated from each other by a predetermined distance, and both ends of each are connected to a plurality of connecting thin tubes. Connecting part 1-3
They are connected by This kind of loop-type thin tube heat pipe completely satisfies the demands of the conventional industry.
It is extremely easy to handle, the installation work is simplified, and it is also possible to install multiple devices through narrow gaps.

する。[Problems to be Solved by the Invention] A loop-type capillary heat pipe with separate heat receiving and dissipating sections as illustrated in FIG. On the other hand, it comes at the expense of its important features. In other words, it is clear that the characteristic that the pressure loss in the tube is compensated for by nucleate boiling in the heat receiving section every turn and the circulation propulsion force is restored is lost. Therefore, the following problems occur in the loop type thin tube heat pipe with separate heat receiving and dissipating parts.
ａ、受放熱部具ターン数及び直管部の長さに限界があり
、大容量化が困難である。これは管内圧力損失の累積に
起因する。a. There are limits to the number of turns of the heat receiving and dissipating component and the length of the straight pipe section, making it difficult to increase the capacity. This is due to the accumulation of pressure loss within the pipe.
ｂ、水平ヒートモードにおける熱輸送能力が大幅に低下
し、トップヒートモードにおいては作動が困難となる。b. The heat transport capacity in horizontal heat mode is significantly reduced, and operation in top heat mode becomes difficult.
即ち従来の通常ヒートパイプと類似の性能となる。これ
も上述と同様に管内圧力損失の累積により作動液循環推
進力が低下し重力を克服することが困難となることに因
る。In other words, the performance is similar to that of a conventional ordinary heat pipe. This is also due to the fact that the hydraulic fluid circulation driving force decreases due to the accumulation of pressure loss within the pipes, making it difficult to overcome gravity, as described above.
Ｃ１放熱部の適冷はかえって性能低下の原因となる。こ
れは放熱部内作動液の蒸気成分が凝縮により殆ど失なわ
れることにより作動液循環推進力が低下することによる
。Proper cooling of the C1 heat dissipation section may actually cause performance deterioration. This is because most of the vapor component of the working fluid in the heat dissipation section is lost due to condensation, resulting in a reduction in the driving force for circulating the working fluid.

める。(B) Structure of the invention [Means for solving the problems] As a means for solving the above-mentioned problems, a predetermined part of the meandering thin tube container of either or both of the heat receiving part and the heat radiating part is connected to the thin tube container. A structure is adopted in which a predetermined part of the high temperature side connecting capillary container, which is a high temperature steam flow path, is connected by a short-circuit capillary tube, and a short-circuit flow path is formed for a part of the working fluid circulation flow. The short-circuiting capillary tube that short-circuits each predetermined portion of the capillary container with the capillary container distributes the working fluid vapor, which was applying a strong propulsive force only to the upstream turn of the meandering, to the downstream side after the middle turn. This ensures smooth circulation of the condensed working fluid within the heat dissipation section.

液の循環を円滑ならしめる。The short-circuiting capillary that short-circuits a predetermined portion of each of the low-temperature side connecting capillary container, which is the condensed working fluid flow path, and the heat dissipating meandering capillary container, reduces the suction force (heat receiving The rapid expansion and contraction of steam bubbles due to nucleate boiling generated in the middle section generates a propulsive force in the connected thin tube container on the high temperature side and a suction force in the connected thin tube container on the low temperature side.) is also distributed to the upstream side before the middle section. This ensures smooth circulation of the condensed working fluid within the heat dissipation section.

させる。The short-circuiting capillary tubes that short-circuit predetermined portions of the high-temperature connecting capillary container and the heat-receiving section meandering capillary container with each other reduce the steam pressure in the heat-receiving section and also reduce the steam flow rate. Reduces pressure loss.

せしめ低温細管からの作動液吸入を容易にする。The short-circuiting capillary that short-circuits a predetermined portion of each of the low-temperature connecting capillary container and the heat-receiving part meandering capillary container reduces the suction force generated in the heat-receiving part from being lost due to pressure loss within the pipe, and reduces the operation from the low-temperature capillary. Facilitates liquid inhalation.

設される逆止弁の規制方向で自ずから決定される。When directly short-circuiting a predetermined portion of the heat-receiving section meandering capillary container and a predetermined portion of the heat dissipating section meandering capillary container using a short-circuit capillary, it is possible to efficiently use a high-temperature gas-phase rich working fluid or a low-temperature liquid-phase rich working fluid. It is more effective because it can be introduced into the heat receiving and radiating section. In this case, whether the working fluid flowing through the short-circuit tube becomes high or low temperature is naturally determined by the regulating direction of the check valve disposed in the short-circuit tube.

The suction force of the working fluid generated in the low-temperature side thin tube container due to the vibration of the valve body of the check valve 2-1 is not reached due to pressure loss.A part of the working fluid is sucked from the connecting part at the top of the meandering thin tube container at the heat dissipation section and the pressure is increased. Alleviates losses and smooths circulation of hydraulic fluid.

The short-circuit capillary tubes c-1 and c-2 reduce the loss of propulsion of the generated steam due to the pressure loss inside the tube in the meandering capillary container with a length of 100 cm, reduce the steam generation to 1 volume, and improve the circulation of the working fluid. Make things go smoothly.

し、り熱部内の蒸気発生を容易ならしめる。The short-circuit thin tubes d-1 and d-S counteract the pressure loss inside the meandering thin tube container of the heat receiving section, help the refluxing working fluid smoothly flow into the heat receiving section, and assist the circulation of the working fluid within the loop. This makes it easier to generate steam in the heated section.

For example, in the case of the top heat mode as shown in Fig. 1 σ, the working fluid in the low-temperature side connected thin container is sufficient with the help of gravity alone, so the short-circuit thin tube on the container side is unnecessary, and the pressure loss is reduced by making the pipe thicker. In many cases, it is sufficient to simply reduce the amount.

A predetermined portion of the meandering thin tube container of heat radiation section 1-2 is directly short-circuited to a predetermined portion of the meandering thin tube container of heat dissipation section 1-2. The short-circuit thin tube sends the high water vapor in the heat receiving section to the heat radiating section 1-2, but whether the low-temperature working fluid in the heat radiating section 1-2 is allowed to flow back to the heat receiving section 1-1 is determined by the reverse direction installed therein. Stop valve 5-2.5~1
is automatically determined by the direction of flow regulation. All of these are very effective because they can simultaneously relieve the pressure chambers in the pipes in the heat receiving section 1-1 and the heat dissipating section 1-2.
