The present invention relates to a heat pipe for long distance heat transfer, and more particularly, an evaporator for evaporating a working fluid to form vapor, and a condenser for dissipating heat to the outside of the vapor transferred at a predetermined interval from the evaporator. And a conveying part formed to communicate the evaporation part and the condensation part to convey steam, and a condensate recovery path or a return pipe is formed to recover the condensed water generated by condensing the vapor in the condensation part, so that the whole is enclosed. In order to improve the point that it is limited to the short-range application, the return pipe formed for the condensate conveyance function of the connecting pipe is conventionally removed so that it is possible to supply long-distance calories and reduce material costs regardless of terrain. It is about a heat pipe.

In general, heat refers to a role of raising the temperature of an object and causing a change of state. As a kind of energy, when the internal energy of an object changes, part or all of the change is released as heat. In general, changes in the internal energy of an object are caused by contact between objects of different temperatures, chemical changes in the material, electromagnetic processes, and the exchange of mechanical work with the outside.

Conversely, heat can be converted into other forms of energy. The theory that treats this energy entry and exit theoretically is called thermodynamics.

Heat pipe means a pipe for efficiently transferring heat. It is also called heat transfer tube. It was manufactured by General Motors of the United States in 1942 for heat dissipation of spacecraft.

It is a pipe exhausted from the inside, filled with volatile liquid inside a lot of small holes. When heat is applied to one end of the pipe, the liquid vaporizes and evaporates, moving to the other end with thermal energy. It dissipates at the other end of the pipe and condenses back into the liquid and returns to its original position along a separate pipe or other condensate return path.
Apparently, even in the case of a single pipe, it is a dual circuit of the steam and condensate passages within the pipe. In this case, a single connecting pipe or a single function means a pipe having a normal cross section, and means a pipe without porous fiber for the condensate recovery passage, and even if some condensate is formed, Condensate passages are not formed except where they collect from low to low.

Copper, stainless steel, ceramics, tungsten, etc. are used for the main body material, and porous fibers, etc. are used for the inner wall in order to increase the transfer path of the condensation recovery liquid using osmotic pressure.

Here, the heat pipe is a super-heat conductor, the operation principle is a heat carrier that transfers heat to both ends by using a phase change caused by evaporation and condensation when the working fluid injected into the vacuum-sealed container is endothermic or dissipated. to be.

In addition, the heat exchanger and the heat exchanger of the evaporator of the heat pipe and the heat exchanger of the condenser are cut to a certain length of a circular container such as a pipe made of stainless steel, copper, etc. to a certain length, and welded with a stopper at one end to form a hermetic seal. It forms a heat medium injection hole through which the heat medium can be injected, injects the internal vacuum and the heat medium (= thermal conductive composition), and seals it.In the case where the contact surface where the heat pipe is to be installed is wide and flat, several heat pipes are pressed directly onto the contact surface ( Or a heat pipe embedded type cooler (= thermal spreader cooler) in which the heat pipe is embedded in a heat-sink with pins fixed and flat on one side. I'm using it.

However, when the heat pipe is compressed according to the contact surface, the diameter of the circular tube should be 10 mm or less, and the contact surface should be larger than the crimp surface of the circular tube, or a plurality of heat pipes should be attached to maximize the heat dissipation performance. The problem that causes a rise occurs.

Accordingly, the present invention has been made to solve the above conventional problems,

An evaporator for evaporating the working fluid to form steam, a condenser for dissipating heat transferred to the outside from the evaporator by a predetermined interval, and a single unit for transporting only evaporated fluid vapor by communicating with the evaporator and the condenser It is composed of a conveying unit formed of a pipe connecting tube of a general type having a function, the working fluid supply is formed to replenish the working fluid evaporated in the evaporation unit from the outside, the condensate generated by condensing steam in the condensation unit to the outside As the condensate discharge part is formed to be discharged into the air, the recovery pipe formed for the condensate conveyance function of the connection pipe is removed in the past, so that long-term heat can be supplied regardless of the terrain and features, and to prevent heat loss due to the long-distance transfer. To reduce the manufacturing cost and reduce the material cost by forming a general-purpose pipe connector with a single function as insulation It has a purpose.
