The heat receiving section and the heat dissipating section, which are formed by the meandering of the heat receiving section capillary container 1 and the heat dissipating section capillary container 2, are connected by a high temperature connecting capillary tube 3 and a low temperature connecting capillary tube 4 to form a loop. The working fluid in the heat-receiving section thin tube container 1 heated by the heating means 6 flows through the check valve 5-1.
5-2 circulates in the direction of the arrow, that is, in the order of heat receiving section capillary tube container 1 -> high temperature connecting capillary tube 3 -> heat radiating section capillary tube container 2 -> low temperature connecting capillary tube 4. At this time, the gas-phase-rich state of the 2
The working fluid of the phase mixed fluid is cooled by the cooling means 7 and lowered in temperature, and at the same time most of the gas phase components (vapor bubbles) are condensed and changed to a liquid phase rich state.

めて循環を開始せしめる。At this time, most of the propulsive force given by the evaporation boiling of the working fluid in the heat receiving section and the propulsive force accumulated as the vapor pressure of the gas phase components are attenuated, and the liquid phase rich working fluid in the low temperature connecting capillary 4 is attenuated. In this case, the driving force for the flow to flow back into the heat-receiving portion thin tube container 1 is extremely weak. This tendency is particularly strong in the top heat mode as shown in Fig. 2, when the low-temperature connecting tube 4 is long and the water level difference between the heat receiving and radiating parts is large, and the working fluid in the heat receiving part becomes insufficient at startup, restarting after stopping, etc. It often becomes difficult to operate due to The auxiliary heat receiving section 10 in FIG. 2 is a measure against such operational difficulties, and is designed to connect the auxiliary heat receiving section 10, the check valves 5-3, 5-4, and the auxiliary heating means 11 disposed before and after the auxiliary heat receiving section 10. The combination serves as a means of assisting circulation. Auxiliary heat receiving section 10 heated by auxiliary heating means 11
The boiling of the hydraulic fluid inside generates a strong propulsive force by the action of the check valve 5-3, 5-4, which propels the downstream hydraulic fluid into the heat receiving section. The working fluid boils in the heat-receiving section capillary container 1 and generates high pressure, which triggers the circulation of the working fluid, propelling all the working fluid in the loop-type capillary container in a predetermined direction and starting the circulation.

Ta. In other words, when the auxiliary means is used continuously all the time, the entire amount of the working fluid fed into the heat receiving part from the low temperature connecting capillary is heated to a temperature above the boiling point, and the low temperature operation is performed by cooling the heat radiation part in the heat radiation part. This could lead to the loss of the original purpose of the loop-type capillary heat pipe, which is to cool the heat-receiving part with liquid or to feed low-temperature working fluid to efficiently absorb heat from the heat-receiving part. there were. The present invention solves this problem and provides a means to supplement and strengthen the operation of the loop-type capillary heat pipe by continuous use.

However, the propulsion energy imparting means is not dependent on boiling of the working fluid due to thermal energy or vapor pressure, but is based on mechanical energy.
This is a feature of the present invention.

点を解決する。The principle of operation of a loop-type capillary heat pipe is based on vapor pressure fluctuations that occur before and after the check valve due to evaporation and boiling of the working fluid in the heat receiving section, and pulse-like pressure waves that propagate within the circulating working fluid. Fluctuations in vapor pressure cause a breathing effect between pressure chambers formed by partitioning a loop with multiple check valves, and pulsed pressure waves generate vibrations in the valve body of each check valve. The check action creates a driving force for the working fluid, which circulates the working fluid and becomes the driving force for the operation of the loop-type capillary heat pipe. The present invention solves this problem by generating the breathing action between the pressure chambers caused by evaporation and boiling of the working fluid and the vibration of the valve body using an external mechanical force applied to the container to generate a circulation assisting action.

合わせであっても良い。FIG. 1 shows an example of a loop-type capillary heat pipe according to the present invention. The difference from the conventional example lies in the configuration of the circulation assisting means, and the circulation assisting means of the conventional example includes an auxiliary heat receiving section 10, an auxiliary heating means 11, and check valves 5-3 .
5-4, in the present invention, the circulation assisting section 8, the internal volume varying means 9, and the check valves 5-4 before and after the circulation assisting section 8,
It consists of 3.5-4. Naturally, the direction in which the hydraulic fluid circulation direction is restricted by the check valve 5-3, 5-4 coincides with the hydraulic fluid circulation direction. The circulation auxiliary section 8 provided therebetween has a structure that facilitates internal volume variation due to the action of the internal volume variation means 9. For example, its inner and outer diameters may be enlarged, or it may be formed into a telescopic shape. In addition, in order to withstand the internal volume fluctuation external force that is repeated nearly infinite times, a highly elastic and strong material is used as the forming material. 1 and 2 have exactly the same structure except for the circulation assisting means. The internal volume varying means 9 may have any structure as long as it can periodically vary the internal volume of the circulation assisting section 8. Further, the internal volume variation may be a variation such as a breathing movement, a pulse-like variation, or a combination thereof.

如きことは無い。By repeating this action, the working fluid in the low temperature connecting capillary tube 4 is given an intermittent driving force and is sent into the heat receiving section capillary container 1. The pumped working fluid immediately boils and vaporizes, and is given a strong driving force by the action of the check valve 5-1. It is fed into the thin tube container 2, is heat-radiated and cooled, and is converted into a liquid-rich low-temperature working fluid, which is then transferred to the low-temperature connecting thin tube 4
It flows back into the circulation assisting section 8 through the. As this cycle repeats itself, the working fluid in the loop-type capillary heat pipe continues to circulate actively and continues to operate well as a heat pipe. In other words, the loop-type thin tube heat pipe, which had lost propulsion and was difficult to operate, was activated, regardless of the bottom heat mode or top heat mode, or regardless of the water level difference between the heat receiving part and the heat dissipating part. Furthermore, good operation continues regardless of the bending state of the connecting capillary tubes 3 and 4. In this case, although the auxiliary propulsive force is applied intermittently by the circulation auxiliary means, the working fluid circulating inside the loop-type capillary container is a two-phase mixed fluid, and due to the cushioning effect of its gas phase component, the actual working fluid The circulation speed becomes a procedural flow. Further, the internal volume varying means does not require a very strong external force to operate. The reason for this is due to the difference in pressure distribution within the loop-type capillary container. In Fig. 1, between the check valve 5-1, the heat-receiving part capillary container 1, and the high-temperature connecting capillary tube 3, the boiling vapor pressure of the working fluid in the heat-receiving part, and the vapor of the gas phase component in the working fluid, which is a two-phase mixed fluid. The pressure is sufficiently maintained, and the circulation driving force of the hydraulic fluid is also sufficiently maintained. However, in the heat dissipation section, the vapor pressure of the gaseous components is lost along with the heat dissipation in the thin tube container 2, and the vapor pressure is further lost due to condensation of the gaseous components. The pressure inside the pipe is significantly reduced due to the pressure loss within the pipe, and the external force required to change the internal volume of the circulation assisting section 8 does not require a very strong external force. Although the closing force of the check valve 5-1 due to the pressure inside the heat receiving section 1 is strong, as can be seen from the operating principle of the loop-type thin tube heat pipe, the valve body of the check valve 5-1 is similar to the check valve 5-2. The valve seat is in a vibrating state in which high pressure and low pressure are alternately repeated at high speed due to the interaction with There is no.

い。In the loop-type capillary heat pipe, the circulation driving force of the working fluid is not completely lost even in the low-temperature connecting capillary tube 4, and even in the top heat state as shown in Fig. 1, the circulation speed decreases and the heat transport capacity decreases. Since the water level is only decreasing, the circulation assisting means only needs to have a circulation assisting ability corresponding to the water level difference between the heat receiving and radiating parts. That is, when the water level difference is 5 m, it is sufficient to apply a propulsive force of 0.5 kg/al, and the operation of the internal volume varying means does not require a large amount of work.

れを作動せしめて、ループ型細管ヒートパイプの適用姿
勢に関係なく高性能を発揮させることが出来る。Since the circulation assisting means according to the present invention does not increase the temperature of the low-temperature working fluid as illustrated in FIG. 2, it does not reduce the heat transport efficiency of the loop-type capillary heat pipe. Furthermore, by adding a small amount of energy, the deterioration in performance caused by the low-temperature connecting capillary tube 4 is prevented, and the heat transport ability is greatly improved. Therefore, not only can it be used as a trigger at startup and restart, but it can also be activated at all times, allowing high performance to be exhibited regardless of the position in which the loop-type thin tube heat pipe is applied.
