Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a heat pipe unit configured in a plate shape.

(Conventional technology) Conventionally, plate-shaped heat pipes were
No. 190291 and others.

Although forming a heat pipe into a plate shape has various advantages in terms of manufacturing costs, uses, etc., conventional heat pipes have room for improvement in terms of thermal efficiency and ease of handling.

(Problems to be Solved by the Invention) The present invention aims to solve the above-mentioned conventional problems and provide a plate-shaped heat pipe unit that has good thermal efficiency and is easy to handle.

(Means for Solving the Problems) The present invention aims to achieve the above objects by: 1. A plate-shaped container, a wick provided along the inner surface of the container, and a hydraulic fluid contained in the container. A plate-shaped heat pipe unit consisting of the heating and cooling pipes attached to either or both of the upper and lower ends of the container, and a guide plate that is provided close to the heating and cooling pipes and guides the dripping working fluid to the wick. This is what we propose.

(Function) (1) The unit of the present invention has the configuration described in the claims for utility model registration, and in particular has a guide plate that guides the dripping hydraulic fluid to the wick, so that heat between the hydraulic fluid and the container (its wall surface) is reduced. There is sufficient exchange and thermal efficiency.

(2) The unit of the present invention has the same configuration as above, and in particular, it has a built-in heating and cooling pipe, so it can be used as is and is easy to handle.

(Example) The plate-shaped heat pipe unit of the present invention will be described below according to an example shown in the drawings.

1 and 2 show a plate-shaped heat pipe unit of the present invention, which has a plate-shaped container 1 made of iron, copper, aluminum, or the like.

A mesh screen wick 5 made of stainless steel, brass, etc. is provided along the inner surface of the container 1.

Further, the container 1 contains a working fluid 6 such as fluorocarbon, alcohol, or water.

Next, a heating and cooling pipe 3 for heating or cooling the working fluid by flowing hot water, water, Freon gas, etc. into either the upper or lower end of the container 1 is installed at a distance from the container wall, except for the penetrating part. It is installed while maintaining the

A guide plate 4 is provided adjacent to the heating/cooling pipe 3 for guiding the working fluid 6 dripping from the heating/cooling pipe 3 during cooling to the wick 5.

As this guide plate, it goes without saying that a so-called plate material without holes such as metal or plastic may be used, but also a porous plate material, wire mesh, cloth, etc. may be used for the purpose of guiding the liquid.

The operation of the plate-shaped heat pipe unit of the present invention shown in the above embodiments is as follows.

That is, when used for air conditioning, cold water of about 7 to 12 DEG C., which is used for air conditioning, for example, is flowed through the heating and cooling pipe 3 in the state shown in FIGS. 1 and 2.

As a result, the upper end of the container 1 is cooled, and the working fluid 6 is liquefied at the outer periphery of the heating and cooling pipe 3.

The liquefied working fluid 6 is guided by the guide plate 4, reaches the wick 5, and then flows along the wick 5 while evaporating.

As a result, the temperature of the container 1 (its wall surface) decreases and a cooling effect is exerted.

Here, since the working fluid evaporates at a temperature that depends on the pressure inside the container, the container wall is cooled to a uniform temperature.

Furthermore, since the heating and cooling pipes are installed at a distance from the container wall except for the penetrating portion, the temperature of the container wall does not drop to near the temperature of the cooling water, and condensation does not occur. Needless to say, appropriate heat insulation (cooling) work is performed on the external part of the heating and cooling pipe from the part that penetrates the container wall.

The above is a case where the container is used for cooling, but when it is used for heating, the container 1 is turned upside down and, for example, hot water of 40 to 60° C. for heating is poured into the heating and cooling pipe 3.

As a result, the working fluid 6 that has evaporated on the outer periphery of the heating and cooling pipe 3 condenses on the inner surface of the container 1, producing a heating effect.

In this case as well, the working fluid condenses at a temperature that depends on the internal pressure of the container, so that it is heated uniformly with the container wall.

Furthermore, since the heating and cooling pipes are installed at a distance from the container wall, the container wall will not reach the same temperature as the hot water.

FIG. 3 shows another plate-shaped heat pipe unit of the present invention, which has the following features compared with those shown in FIGS. 1 and 2.

That is, heating and cooling pipes 3 and 8 are provided at both the upper and lower ends of the container 1.

This allows the container 1 to be used for cooling and heating without changing its vertical position.

The one in FIG. 3 also has the guide plate 4 shown in FIG. 2, although it is not shown.

In addition, in the unit shown in Fig. 3, the heating and cooling pipes 3,
Regarding 8, both cooling and heating piping may be provided, but as shown by the dashed line in FIG. It is also possible to omit the switching operation.

(Effects of the invention) The embodiments of the plate-shaped heat pipe unit of the invention are as described above, and the effects thereof are listed below.

(1) The unit of the present invention has the configuration described in the claims for utility model registration, and in particular has a guide plate that guides the dripping hydraulic fluid to the wick, so that heat can be transferred and received sufficiently between the hydraulic fluid and the container (its wall surface). It is thermally efficient.

(2) The unit of the present invention has the same configuration as above, and is particularly easy to handle because it incorporates a heating and cooling pipe.

(3) In the unit of the present invention, the inner wall of the container has an evaporation temperature or a condensation temperature that corresponds to the internal pressure of the container, so the outer surface of the container has a uniform temperature and provides a suitable heating and cooling effect.

(4) In the unit of this invention, the heating and cooling pipe is installed with a distance from the container wall, except for the penetrating part, so the temperature of the container wall does not become almost the same as the cold water during cooling, and condensation does not occur. There's nothing to do.

Furthermore, even during heating, the temperature does not become nearly the same as the heat source, so there is no need to worry about burns.
