る。[Detailed explanation of the invention] (a) Industrial application field This invention guides the vapor of the working fluid evaporated in the evaporation part to the condensation part located above the evaporation part.
The present invention relates to a heat pipe in which heat is transferred in one direction from the evaporator to the condenser by returning the condensed working fluid in the condenser to the evaporator by gravity.

り、同様の結果をもたらす。(b) Prior Art In this type of heat pipe, condensation in the condensing section tends to occur at the beginning of the condensing section, and the efficiency is poor when the entire condensing section is used as a heat exchanger. In addition, the condensed working fluid may interfere with the vapor of the working fluid in the condensing section, which may prevent the evaporation from penetrating into the deep part, resulting in a similar result.

下端に連通させたものが提案されている。 Therefore, as disclosed in Japanese Patent Application Laid-Open No. 51-81070, the evaporating section and the condensing section are connected by a gas pipe through which the vapor of the working fluid flows and a liquid pipe through which the condensed working fluid flows down. It has been proposed that the liquid tube is inserted into the condensing part up to the upper position, and the liquid pipe is connected to the lower end of the condensing part.

きなかつた。 In the heat pipe described above, the vapor of the working fluid and the condensed working fluid do not interfere with each other in the condensing section.
The flow of hydraulic fluid becomes smoother. However, since the evaporation section and the condensation section are connected by gas pipes and liquid pipes, there are many connection points such as brazing, which reduces reliability against leakage of the working fluid and causes an increase in costs. Ta. In addition, since two pipes are connected to the condensing section, the gas pipe must be installed eccentrically to the condensing section, which causes the steam in the condensing section to flow unevenly, making effective use of the heat transfer surface of the condensing section. I couldn't do it.

This lead-out pipe is arranged almost coaxially within the condensing part at a distance from the inner wall of the condensing part, and the condensed working liquid is connected to the evaporator at the lowest part of the lead-out pipe in the condensing part. It is configured with a return hole for returning it to the original state.

である。 According to this idea, the vapor of the working fluid evaporated in the evaporator is guided deep into the condensing part through the outlet pipe, and the working fluid condensed in the condensing part is evaporated from the return hole provided at the bottom of the outlet pipe in the condensing part. The vapor of the working fluid and the condensed working fluid do not interfere with each other, allowing smooth circulation of the working fluid. In addition, it is only necessary to connect the outlet tube to the condensing part in an airtight manner, and the number of connection points in the condensing part is only one, which increases the reliability against leakage of the working fluid and can be manufactured at low cost. In addition, since the outlet tube is inserted almost coaxially within the condensing section, the vapor of the working fluid drawn out from the outlet tube is evenly distributed in the space between the inside of the condensing section and the outlet tube, and the inner wall of the condensing section (heat transfer The condensed working fluid attached to the condensing surface can be moved toward the lower end of the condensing section, making it possible to effectively utilize the heat transfer surface.

Reference numeral 1 designates a heat pipe in which a heat collecting plate 3 is fixed to an evaporating section 2, the tip of which is opened to form an outlet tube 4, and a bulging condensing section 5 is connected to cover the outlet tube 4. There is. The evaporating section 2 and the condensing section 5 communicate with each other through an outlet tube 4, and the inside thereof is kept in a high vacuum and sealed, and an appropriate amount of working fluid is sealed inside the evaporating section 2. The outlet cylinder 4 extends to the middle of the condensing part 5 and has an opening, and is inserted almost coaxially within the condensing part so that a uniform interval 6 is formed between it and the inner wall of the condensing part 5. ing. 7... is a return hole drilled at the lowest part of the outlet tube 4 in the condensing part 5 at a location opposite to the interval 6;
The condensed working fluid is returned to the evaporator 2.

なうものである。 Thus, when heating or heat is collected in the evaporation section 2, the working fluid evaporates and rises, entering the condensation section 5 from the tip opening of the outlet tube 4, and also entering the gap 6. It then condenses and falls, and the condensed working fluid returns to the evaporation section 2 through the return holes 7. Furthermore, as the condensed working fluid returns from these return holes 7, circulation paths for the evaporated and condensed working fluids can be formed without interfering with each other, and the evaporated working fluid smoothly enters the gap 6. Since the condensation section 5 is bulged, the heat exchange surface is large, and condensation occurs smoothly within the gap 6, resulting in efficient heat exchange.

Inside, the vapor of the working fluid and the condensed working fluid do not interfere with each other, allowing smooth flow of the working fluid. Moreover, since the evaporating section 2 and the condensing section 5 are connected by one outlet pipe 4, if the evaporating section 2 and the discharging section 4 are integrated, it is only necessary to connect the discharging section 4 and the condensing section 5 in an airtight manner. heat pipe 1
, only one connection point is required, reliability against leakage of hydraulic fluid can be increased, and manufacturing can be done at low cost. In addition, since the outlet tube 5 is inserted almost coaxially into the condensing section 5, the vapor of the working fluid that has entered the condensing section 5 from the tip opening of the outlet tube 5 flows through the opening between the inner wall of the condensing section and the outlet tube 5. It is distributed evenly over 6 intervals. For this reason, the condensing section 5
The condensed working fluid adhering to the inner wall (heat transfer surface) of the condenser is quickly swept downward by steam, making it possible to effectively utilize the heat transfer surface of the entire condensing section.
