Abstract

PURPOSE: A cooling device using a heat pipe is provided to effectively and speedily cool beverage and liquid in a can, a glass bottle and a plastic bottle. CONSTITUTION: A cooling device using a heat pipe includes a gasifying chamber(12) in which the heat pipe(11) is inserted partially. Refrigerant introduced via an inlet(13) is gasified in the gasifying chamber and removes the heat of the heat pipe from the surface of the heat pipe. The refrigerant is discharged via an outlet(14) of the gasifying chamber. The gasifying chamber is formed with a corrugation part(15) on an inner surface to remove the heat of the heat pipe as much as possible. The heat pipe is mounted with a heat absorbing plate(16) at a part to receive a beverage.

Description

Cooling Device with Heat Pipe {Cooling Device with Heatpipe}

The present invention relates to an apparatus for cooling beverages and liquids, and more particularly, to an apparatus capable of rapidly cooling various beverages such as alcoholic beverages, water, carbonated beverages, and industrial liquids. It is easy to carry when it is manufactured in a small size, and the structure is simple even when used for industrial use.

Conventionally, there have been inconveniences such as using an ice box to keep drinks cold when there is no refrigeration facility. The proposed chillers to solve this problem can be classified into three categories. The first is to cool the beverage in the can using the vaporization heat of the refrigerant by providing the refrigerant in the can itself. The second method is to put a can into a container in which the refrigerant can be vaporized, and eject the refrigerant into the container to absorb heat from the surface of the can to cool it. The third method is to insert a tube through which the refrigerant can pass into the beverage container and supply the refrigerant from one side of the tube to absorb the heat of the beverage as the refrigerant leaves the tube.

The present invention can be applied to all beverages in small cans, large cans, glass bottles and plastic bottles, and to provide a cooling device that is easy to apply and has excellent heat absorption efficiency. In addition, it provides a simple structure to maximize the heat transfer rate and the efficiency of the refrigerant.

In the present invention, the refrigerant is vaporized in the vaporization chamber of the cooling apparatus without directly entering the beverage container, and the heat of vaporization of the refrigerant is directly transmitted to the beverage through the heat pipe. In this case, the refrigerant is a generic term for not only conventional conventional refrigerants, but also a substance that absorbs heat of vaporization while being vaporized at room temperature and atmospheric pressure (1 atm). There is no technical problem in applying any material as long as vaporization heat is available.

Heatpipes are heat superconductors and have a thermal conductivity of several hundred times that of copper. A small amount of working fluid (distilled water, acetone, ethanol, methanol, etc.) is injected into the hollow metal pipe and sealed by lowering the pressure to near vacuum. The heat is transferred by latent heat by vaporization and liquefaction of the working fluid. It can transfer a large amount of heat quickly. In particular, the heat transfer efficiency is maximized in the condition that the lower temperature is high and the upper temperature is low as in the present invention. Currently, heat pipes are used in various fields that require fast heat transfer such as cooling devices, waste heat recovery, and heating facilities for various electronic devices.

As shown in FIG. 1A, which illustrates a cross-sectional view of the cooling apparatus of the present invention, one portion of the heat pipe 11 is placed in the vaporization chamber 12, and the refrigerant entering the inlet 13 is vaporized in the vaporization chamber 12. While taking heat from the surface of the heat pipe 11 and exits the outlet 14, the heat pipe cools the beverage by transferring heat at a very high speed when a temperature difference between the beverage and the vaporization chamber 12 occurs. . The vaporization chamber 12 has an inlet 13 through which the refrigerant is injected and an outlet 14 through which the vaporized refrigerant exits, and serves as a space in which the refrigerant is vaporized, and the refrigerant absorbs a lot of heat on the surface of the heat pipe 11. The wrinkles 15 may be formed therein as shown in FIG. The inner pleats 15 of FIG. 1B are formed on the inner wall of the vaporization chamber in a female thread-like structure to allow the refrigerant to absorb heat while traveling around the heat pipe 11 several times. FIG. 1 (c) shows that the wrinkles 15 are formed inside the vaporization chamber 12 and the heat absorbing plate 16 is installed in the portion of the heat pipe 11 to be contained in the beverage to increase the heat absorption area of the beverage. . The presence or absence of such wrinkles and the shape of the wrinkles, the presence and absence of the heat absorbing plate 16 can be designed in a variety of ways so that their modified forms belong to the scope of the present invention.

When the cooling device as described above is inserted into the beverage as shown in FIG. 2 and the refrigerant is injected into the inlet 13, the heat pipe absorbs the heat of the beverage 22 at a very high speed to cool the beverage 22. . At this time, the container 21 of the beverage does not matter in any form and only the inlet enough to insert the heat pipe 11 is to be secured. In addition, in the case of carbonated drinks, it is also possible to block the stopper 23 while the beverage 22 is cooled.

3A and 3B illustrate the movement of the coolant 31. In FIG. 3A, an inlet 13 is provided at a lower side of the vaporization chamber 12, and the coolant 31 is connected to the valve 32. It enters the injection hole 13 through the vaporization in the vaporization chamber 12 is to absorb the heat of the heat pipe (11). In FIG. 3B, an injection hole 13 is provided above the vaporization chamber 12b, and the refrigerant 31 enters the injection hole 13 through the valve 32, and is vaporized in the vaporization chamber 12 to heat the pipe. It absorbs heat from 11). The valve 32 serves to adjust the injection amount of the refrigerant 31, the position of the inlet 13 and outlet 14 can be changed as the designer intends. The dashed arrows indicate the inlet and outlet paths of the refrigerant.

FIG. 4 shows that the heat sink 41 made of metal is installed in the heat pipe 11 instead of the pleats 15 inside the vaporization chamber 12, where the heat sink 41 is the heat pipe 11 in the vaporization chamber 12. While increasing the efficiency of heat dissipation, the vaporized refrigerant travels inside the vaporization chamber 12 along the dashed line indicated by (40), absorbing heat from the heat sink 41 and the heat pipe 11 and exiting the outlet 14. It serves as a guide to get out. The preferred structure of the heat sink 41 has a hole 51 into which the heat pipe 11 can be inserted in the center and a groove 52 through which the refrigerant can flow out on one side, as shown in FIG. As shown in (a), it is advantageous to arrange the grooves 52 in opposite directions. In FIG. 5A, a heat dissipation plate 41 is exemplarily shown in an exemplary order, and the heat pipe 11 is omitted to avoid congestion in the drawing.

The refrigerant 31 used in the present invention is in a liquid state, and the liquid refrigerant 31 in the liquid state is injected into the vaporization chamber 12 to vaporize in a gaseous state to absorb the vaporization heat. The refrigerant that is vaporized and exits the outlet 14 may be recovered or left to blow into the atmosphere. If the refrigerant is a combustible material, a combustion device may be installed in the outlet 14 to combust the refrigerant.

By using the cooling device of the present invention, the beverage or the liquid can be cooled efficiently and quickly.
