Description

Pipe for transfering fluid

The present invention relates to a fluid delivery pipe, and more particularly to a fluid delivery pipe for improving the efficiency and economics of heating and cooling.

In general, a cooling and heating device is a device for transferring a low temperature heat source to a high temperature or a high temperature heat source to a low temperature by using heat of a refrigerant or heat of condensation.

The air-conditioning apparatus mainly refers to a heat pump, and is classified into an electric heat engine type, a heat source type (waste heat source type), and a geothermal source type according to an electric type and an engine type according to a driving method.

Meanwhile, a heat pipe, which is a fluid transfer pipe for efficiently transferring heat, is used in such a cooling and heating device. The heat pipe is manufactured by injecting and sealing a certain amount of a working fluid (heat transfer medium) into a vacuum pipe. The heat source device is installed at one end of the heat source, and when heat is applied therefrom, the working fluid evaporates and moves to the other end, releasing thermal energy, and condensed back into the liquid by heat exchange to return to the original position.

In other words, the heat pipe is a heat transfer mechanism that transfers a large amount of heat by using evaporation in which the liquid is converted into gas and latent heat absorbed and released when the gas is condensed into the liquid.

These heat pipes can be raised or lowered uniformly in a fast time, and are usefully used for home heating, agricultural greenhouse heating, and geothermal heat recovery.

However, conventional heat pipes are relatively expensive because they use metals such as copper, copper, and aluminum, and require a separate connector to be bent at the bent connection site, resulting in poor workability and difficulty in finding cracks due to impact. Maintenance was difficult and this caused a problem that the durability is lowered.

In addition, the conventional heat pipe has a problem that it takes a long time to control the temperature for heating and cooling because the heat transfer efficiency is not high because the surface area of the heat transfer is mainly because of the circular flat structure.

In order to solve the above problems, the present invention is to solve the problem to provide a fluid transfer pipe that improves the efficiency and economic efficiency of heating and cooling by simply connecting the pipe of the structure and the effective heat transfer structure of the pipe.

In order to solve the above problems, the present invention is provided with a synthetic resin containing polyethylene, the circular portion is provided with a passage for moving the fluid for heating and cooling inside to be usable as a pipe including an excel pipe and a heat pipe; And a synthetic resin integral with the circular portion along the longitudinal direction on the outer circumference of the circular portion, wherein one or more numbers are regularly arranged in at least one or more directions of the longitudinal and circumferential directions of the circular portion, and increase the surface area to be transferred. It provides a fluid delivery pipe comprising a protruding pin extending in the radial direction of the circular portion.

Here, the protruding pin is preferably made of a screw shape extending around the outer periphery in the longitudinal direction of the circular portion. In addition, the protruding pin is formed in the space portion in communication with the passage so that the fluid is moved inside, it is preferable that a plurality is arranged at equal intervals along the circumferential direction of the circular portion. Further, the circular portion is formed to be connected to one end by being formed into a circular pipe portion to be pressed to the other end, it is preferable that at least one packing portion for receiving the packing member for sealing is formed in the pipe portion. In addition, the one end portion is formed as a circular straight pipe portion of one end, the other end is formed of a circular expansion pipe portion is fitted with the straight pipe portion is fitted with a fastening band is preferably coupled to be sealed by being coupled.

Through the above solution, the present invention provides the following effects.

First, since the protruding pins extending in the radial direction of the circular portion are provided, the surface area to be transferred is increased, thereby shortening the time for temperature control, thereby improving heat transfer efficiency, thereby significantly improving the efficiency of heating and cooling.

Second, since the circular part and the protruding pin are integrally made of synthetic resin, it can be manufactured inexpensively, so that the economic efficiency can be improved and the construction can be easily improved when buried by the protruding pin.

Third, a space portion through which the fluid for heating and cooling is moved is formed inside the protruding fins, so that the heat transfer efficiency can be remarkably improved since it can have almost the same thermal conductivity as a circular pipe of a conventional metal material.

Third, by providing a pipe for connecting to one side of the circular portion, by fixing the connection of a plurality of pipes can be extended as needed by the use can be significantly improved construction and usability.

Fourth, the straight pipe portion and the expansion pipe for connecting a plurality of pipes is provided by being fixed by the mutual fastening band, the workability is further improved and can be prevented in advance such as leaks due to construction.

Hereinafter, a fluid delivery pipe according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a fluid delivery pipe according to a first embodiment of the present invention.

As shown in FIG. 1, the fluid delivery pipe 100 according to the first embodiment of the present invention includes a circular portion 110 and a protruding pin 120.

In detail, the circular part 110 is provided with a synthetic resin including polyethylene, and is provided with a passage 111 through which fluid for heating and cooling is moved inside so that it can be used as a pipe including an Excel pipe and a heat pipe.

Here, the circular portion 110 is preferably made of a cylindrical shape provided with a passage 111 on the inside, the passage 111 has the same inner diameter as the inner diameter of the conventional pipe, such as Excel pipe, heat pipe, etc. Is preferred.

In addition, in the case of a heating excel pipe, the fluid is hot water, and in the case of a heat pipe, it is a working fluid such as methanol.

That is, the fluid delivery pipe 100 of the present invention performs heating or cooling by using heat radiation or latent heat while transferring fluids such as hot water and methanol through the inner passage 111, such as the existing Excel pipe and heat pipe. It is used for the purpose.

On the other hand, the outer circumference of the circular portion 110 is provided with a protruding pin 120 is formed of a synthetic resin integral with the circular portion in the longitudinal direction, the protruding pin 120 is one or more number of the circular portion 110 Is regularly arranged in at least one direction of the longitudinal direction and the circumferential direction, and extends in the radial direction of the circular portion 110 to increase the surface area to be transferred.

In this case, the protruding pin 120 may be used for any one of the pipes for the fluid delivery 100 of the present invention, such as an excel pipe or a heat pipe, or an extension length thereof may be determined by a manufacturer. In this case, however, consideration should be given to the flexibility and workability of the pipe, depending on the intended use.

In addition, the protruding pin 120 has one or more numbers regularly arranged in at least one or more of the longitudinal direction and the circumferential direction of the circular portion 110, as shown in FIG. 1, one protruding pin 120 has a screw shape. 2 to 3 or regularly arranged as shown in Figure 2 to 3 to say that is arranged regularly.

In addition, the circular portion 110 and the protruding pins 120 are preferably manufactured integrally for convenience of manufacture, and are preferably made of synthetic resin such as polyethylene.

Of course, the use of copper pipes or cast iron pipes may be considered for the efficiency of heat transfer. However, copper pipes or cast iron pipes are expensive and the rigidity of copper pipes is not flexible, so each element that is bent for construction is welded or T-shaped. It is expensive because it has to be connected with a connector.

Specifically, the heat pipe is manufactured by injecting a working fluid (heat transfer medium) such as methanol, anhydrous ethanol, purified water, or propanone-based liquid, having a low boiling point and a large latent heat of evaporation, into a vacuum metal tube. Is a device that transfers heat as latent heat at the time of phase change by using a phase change from liquid to steam, and is used for heating and cooling piping hose of a house, heating and cooling piping hose of facility plant, and heating and cooling using geothermal heat, etc. Since the heat pipe is made of synthetic resin, the cost is low and the maintenance cost is low, thereby improving the economic efficiency.

In addition, since it is possible to bend and use the heat pipe made of synthetic resin by improving the connection to the connection pipe or welding, etc., when constructing the existing metal heat pipe, it is possible to have excellent workability since it is easy to process and work according to construction.

In other words, synthetic heat pipes are cheaper than other types of pipes, and are light in weight, which can shorten the construction period, thereby providing excellent economic efficiency.

Then, by providing the protruding fin 120 on the outer circumference of the heat pipe, it is possible to increase the heat transfer contact area.

In this case, in order to maximize the efficiency of the heat transfer, the inner side of the protruding fin 120 is preferably formed with a space portion (refer to 221 of FIG. 2B) in communication with the passage 111.

To this end, the circular portion 110 and the protruding pin 120 is manufactured integrally by injection molding.

In addition, the existing Excel pipe is a kind of synthetic resin that does not have high shrinkage and expansion rate due to temperature change and has high corrosion resistance like metal, and has high molecular weight polyethylene structure by special reaction molding equipment. It is a crosslinked high density polyethylene tube changed into molecular material.

In addition, the existing Excel pipe is mainly used as a water supply and hot water pipe, because it is made of a circular flat structure can not transfer heat quickly, the heat transfer efficiency is low.

Moreover, these excel pipes are flexible when used for heating the house, and are laid and laid on the floor of the house, and since their outer periphery is made of a flat circle, the surface area in contact with the floor of the house decreases the heat transfer efficiency. The present invention can increase the heat transfer efficiency by increasing the surface area that is in contact with the bottom of the housing by heat transfer by having a protruding fin 120.

Accordingly, the fluid delivery pipe of the present invention is a pipe made of synthetic resin provided with the protruding fin 120, and is capable of significantly improving heat transfer efficiency due to active heat transfer as compared to the existing excel pipe or heat pipe.

Through this, in the heating of a house, indoor facility of a rural facility house or an air conditioner, the time required to obtain a predetermined temperature for air conditioning is shortened, and the energy consumed as a whole can be greatly reduced.

On the other hand, the protruding pin 120 is preferably made of a screw shape extending around the outer circumference in the longitudinal direction of the circular portion (110).

Here, the screw shape of the protruding pin 120 is preferably formed regularly in the longitudinal direction of the circular portion 110, this screw shape is the circular portion 110 and the protruding pin 120 is integrally manufactured Flexibility is maintained when bending as needed.

Furthermore, when a space portion (see 221 of FIG. 2B) is formed inside the protruding pin 120, the fluid is moved through the inner space of the protruding pin 120 according to the screw shape, thereby providing thermal conductivity of the synthetic resin tube. Complementary efficient heat conduction is possible, so heat transfer through a wider surface area can be made more effective. In addition, the screw shape is a shape that is easy to embed in order to use geothermal heat.

In addition, the protruding pin 120 may be easily fixed when the fluid delivery pipe 100 of the present invention is embedded.

For example, when the fluid delivery pipe 100 of the present invention is used as an excel pipe of a house, cement flows into the space between the protruding pins 120 after piping the excel pipe to the floor of the house to be heated. By being poured, the excel pipe is firmly coupled to the concrete layer.

In addition, since the protruding pin 120 is formed in a regular screw shape along the circumferential direction of the circular part 110, the mutual fixing force between the cement and the screw forming the concrete layer may be improved.

That is, the total sum of the outer surface of the circular portion 110 and the surface area of the protruding pin 120 is larger than the surface area of the pipe of the conventional cylindrical tube, and the contact area can be increased, and the protruding pin 120 and the concrete layer and Because the contact area of the is improved, the heat dissipation is improved widely and the heat transfer effect is improved.

Therefore, since the protruding pins 120 extending in the radial direction of the circular part 110 are provided, the surface area to be transferred is increased to improve heat transfer efficiency, thereby shortening the time for temperature control for cooling and heating, thereby economically improving heat transfer efficiency. Can be increased.

In addition, the protruding pin 120 is formed integrally with the circular portion 110 and injection molding, etc., so it is easy to manufacture and can be inexpensively, and the fluid delivery pipe 100 of the present invention is buried by the protruding pin 120. In this case, it is easy to fix and construction property can be significantly improved.
