Description

Heat Transfer Use Heat Pipe Set}

When the heat pipe is used as an ondol pipe, that is, when the heat pipe is laid down, the working fluid contained in the pipe is laid flat and shallow along the length of the pipe, which significantly reduces the area of the working fluid in contact with the hot water pipe. . The medium that receives the heat from the hot water pipe and delivers it to the heat pipe body is the working fluid.The performance of the heat pipe differs depending on how well the material senses the hot water heat and how well it transmits to the end of the heat pipe body. Even conventional heat pipes installed have no or working fluid in contact with the hot water pipes, so that the side heat pipes may be hot but not cold at all. It is for this reason that the end of the heat pipe is set a little higher than the hot water pipe side in order to collect the working fluid toward the hot water pipe, which requires a lot of cement and sand to cover the ondol heat pipe. Increasing the load on the building not only shortens the life of the building, but also increases all expenses including labor costs.

In addition, most conventional heat pipes sometimes sound like a sizzling or exploding sound as the temperature increases, which is a phenomenon due to insufficient working fluid around the hot water pipe, and the heat heated by the hot water heat of the hot water pipe. This is because there is not enough working fluid around to cool down the pipe as it transfers heat, and as a result of hot or frying pans, water or oil will heat up not enough working fluid, just as it will evaporate with a loud noise. .

Many attempts have been made to maximize the area where the heat pipes are in contact with the hot water pipes to eliminate this phenomenon. However, it is difficult to fully collect the working fluid of the horizontally laid heat pipes toward the hot water pipes. This phenomenon is drastically reduced if there is sufficient working fluid around the hot water pipe receiving area. However, conventional heat pipes have no way of avoiding such phenomenon when used lying down for ondol use.

In order to solve the above problems, the present invention has been envisioned, in which the working fluid 3 in the heat pipe 6 lying on the horizontal side meets with the hot water pipe 7 so as to be brought into contact with the hot water pipe 7. The working fluid absorbent fabric 4 is installed and the working fluid absorbent fabric 4 easily absorbs the working fluid 3 which is shallowly laid on the bottom of the heat dissipation heat pipe by capillary action, so that the entire working fluid absorbent fabric is always sufficient. The working fluid was kept. Then, as shown in FIG. 3, the upper part of the heat transfer heat pipe is installed in the working fluid absorbent cloth, and the lower part is positioned in the hot water pipe in a diagonal direction so that the working fluid 2 in the heat transfer heat pipe 1 is heated in the hot water pipe (7). Since the heat pipe inside the heat pipe is collected in the lower part, the hot water heat in the hot water pipe can be easily transferred to the working fluid absorbent fabric 4, thereby solving the problems of the conventional heat pipe.

Of course, the vertical heat pipe also sounds like an explosion, which occurs because the working fluid gathered at the bottom of the heat pipe becomes hot and vaporizes at once, but the working fluid absorbent cloth 4 of the present invention is enclosed. Moisture is less dense and vaporizes quietly and quickly, like evaporating water vapor when ironing wet clothes, making it less noisy. In addition, the working fluid absorbent cloth always absorbs the working fluid vapor which is trapped in the bottom of the heat dissipation heat pipe by vaporization and vaporized and absorbs the working fluid vapor which is already vaporized and floats in the pipe. Since the working fluid is moistened, the present invention does not need to raise the drag portion of the heat pipe for heat dissipation during installation.

Accordingly, the present invention integrally forms the working fluid absorbent cloth 4 in the working fluid absorbent cloth protective cover 5 in which the heat transfer heat pipe 1 and the hot water pipe side are blocked and the opposite side is opened as shown in FIG. 2. When installed in the middle of the hot water pipe (7) and the heat dissipation heat pipe (6) as shown in Figure 3, the maximum heat efficiency can be expected, construction cost is reduced and heating operation costs are also reduced.

And when the conventional heat pipe is used to provide hot water heat only from one side lying down, there was a closed end that the working fluid does not spread far while evaporated, but when the present invention is installed in the middle of the heat pipe as shown in FIG. It is also effective to make the heat pipe much longer than the conventional one, which is also an advantage of reducing the construction cost and heating operation costs.

Accordingly, the present patent has been made to solve the above-mentioned problems. Since the working fluid in the heat dissipating heat pipe laid down by using the capillary phenomenon can be easily collected in the working fluid absorbent fabric, By not having to increase the use of cement and sand by making the tip higher than horizontal, it not only reduces raw material costs and labor costs, but also absorbs or generates noisy sound from the working fluid absorbent vaporization. Therefore, the user can enjoy a comfortable heating life, and the heat transfer heat pipe in the hot water pipe is transferred to the heat dissipation heat pipe quickly and maximally to provide economic benefits from the individual to the country and more. To create a better heating culture Its purpose is.

The present invention for achieving the above object is to be used in combination with the hot water pipe (7) and heat dissipation heat pipe (6), the preferred embodiment of the present invention will be described in detail by the accompanying drawings as follows.

Fig. 2 is a side cross-sectional view of the present invention, in which a working fluid absorbent cloth 4 is embedded in a round cylinder called a working fluid absorbent cloth protective cover 5, and the heat dissipation heat pipe direction is used to smoothly absorb the working fluid. Although open for the purpose of blocking the opposite side of the hot water pipe direction and half of the heat pipe for heat transfer (1) to the downward direction showing the structure of the working fluid (2) gathered downward to improve the heat transfer.

3 is a side cross-sectional view of the present invention coupled to the hot water pipe 7 and the heat dissipation heat pipe 6, showing an example in which the present invention is installed in the middle of the hot water pipe and the heat dissipation heat pipe.

4 shows that when the heat pipe is to be laid very long, the working fluid which senses the hot water heat cannot be evaporated indefinitely to the opposite end of the heat pipe to transfer heat, and thus the length of the heat pipe cannot be made too long. However, if the present invention is installed in the middle of the heat pipe, it can be made much longer than the conventional one, and an example is shown.

5 is a side cross-sectional view of the working fluid in the pipe when the heat pipe is laid down, as in construction for ondol, showing a state in which the amount of working fluid is not sufficient in the heat pipe of the end portion in contact with the hot water pipe Drawing.

As described above, the present invention improves energy efficiency by facilitating heat transfer of the heat pipe, reduces noise noise caused by heat transfer during heating operation, provides a comfortable heating life, and at the end of the heat pipe during installation. Since the amount of cement and sand is reduced by the increased area and volume, it is possible to extend the life of the building by reducing unnecessary load of the building.
