Description

Heating tube

More particularly, the present invention relates to a heat transfer tube for heating, and more particularly, to a heat transfer tube having a circulation structure and circulating the heat oil, thereby enabling uniform formation of heat over the entire buried area and measuring the presence or absence of air, The present invention relates to a heat transfer pipe for heating that can be easily removed, does not need to always drive a circulating motor, and can reduce noise caused by circulation of fruit oil.

Generally, the heating device is composed of a metal pipe or a PVC pipe storing a hot water heated by combustion heat generated from the boiler, and a boiler for burning oil or gas, and the heated water is heated by heat .

However, since the conventional heating apparatus as described above uses expensive oil or gas as the fuel, the heating cost is high, so that it is economically burdensome to the user, and a separate boiler for burning fuel such as oil or gas is purchased This is even more uneconomical.

In addition, since a space for installing the boiler having a predetermined volume is provided, not only the installation place is limited but also the high-density water is heated, so that a long heating time is required, and a large amount of heat loss And the like.

Therefore, in order to solve the above-mentioned problems, when a room, a flat, or an indoor space of an ordinary building is to be heated, a pipe (an excel pipe) into which a heating medium (heating water or oil) When a power is applied to a heating wire inserted in a heating medium inside a pipe, the heating medium is heated and circulated along the pipe so that heat can be transmitted to the bottom surface, thereby heating the room. Quot;) is gradually increasing.

Such a heating system is known as a means for sealing the both ends of the hot water pipe by inserting the heating wire inside the hot water pipe which is heated and installed on the floor of the building.

In a conventional heating system using a heating medium, there is a method of heating an electric hot water pipe and its apparatus in Patent Registration No. 10-0180211. This allows the hot water pipe to be heated by heating the water of the hot water pipe by inserting a heating wire which is made of copper wire in the entire length of the hot water pipe piped to the floor of the room. The both ends of the hot water pipe are connected to the opened expansion tank, Absorbing the pressure of the pipe to prevent the expansion of the hot water pipe and discharging the air or gas through the expansion tank

Also, in addition to the above-mentioned devices, there have been known a number of heating systems such as 'a sealing structure of a hot-water pipe with built-in heating line' and a hot-water pipe with a built-in heating line 20-0449209 of Registration No. 10-0859901 .

However, in the conventional heating tube electric boiler in which the conventional heating medium is stored, since the heating medium oil is fixed without circulation, when a part of the heating tube is partially provided with a heating means such as an electric heater or an electric heating plate for a long time, The temperature of the heating medium is different from the period in which the heating means is not provided. This causes a problem that the heating wire continuously heats the heating medium.

Therefore, there is a problem that the temperature continuously increases in the section where the warming means is provided, so that the risk of fire is always present.

In addition, there is also a disadvantage in that the heating wire continuously heats the heating medium, thereby consuming a large amount of electric power.

In addition, since the heating wire continuously heats the heating medium, the durability of the heating medium is lowered and the replacement cycle is shortened.

An object of the present invention is to provide a heat transfer tube for heating, in which the heat transfer tube has a circulation structure and the heat transfer oil is circulated so that uniform heat can be formed over the entire buried area.

Another object of the present invention is to provide a heat transfer pipe for heating which can measure the presence or absence of air and can easily remove the air when it senses air.

Another object of the present invention is to provide a heat transfer tube for heating which does not need to always drive the circulation motor.

In addition, the circulation motor of the present invention is mounted in the direction of one of the two ends connected to the heat transfer tube of the reverse Y-type circulation tube, and transfers the heat transfer fluid downward toward the heat transfer tube.

According to another aspect of the present invention, there is provided a control unit for controlling an amount of electric current supplied to the electric hot wire and whether the circulating motor is driven, wherein the control unit sets the vibration value based on the vibration value measured from the air sensor If it is more than the value, the driving of the circulation motor is stopped.

According to another aspect of the present invention, there is provided a heat exchanger comprising: a temperature sensor provided at a plurality of positions of the heat transfer tube for sensing heat radiated from the heat transfer tube; The circulation motor is driven.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 4, an electric hot wire 110 is inserted into a tube, and a heat transfer fluid is filled between the tube and the electric hot wire 110 so that both ends are exposed on a predetermined lengthwise surface, And two ends of the pipe are connected to both ends of the heat transfer tube 100 so that the heat transfer fluid in the heat transfer tube 100 flows in a circulation structure An inverse Y-shaped circulation pipe 200 in which two ends connected to the electro-thermal tube 100 are located below the branch point so that air in the electro-heating tube 100 can be lifted, A circulation motor 300 for circulating the oil in the heat transfer tube 100 and an inverse Y-type circulation pipe 200 connected to the other end located above the branch point of the reverse Y- And the reverse Y-shaped An auxiliary tank 400 for supplying the heating oil as much as the air floated to the annular pipe 200 and a control unit for controlling the amount of electric current supplied to the electric heating wire 110 and whether the circulating motor 300 is driven or not do.

The heat transfer tube 100 is buried in the form of a pipe of a boiler on the bottom surface of a room, a living room, etc., and generates heat when power is input to radiate heat to the outside. And the space between the tube and the electric heating wire 110 is filled with a fluid such as water, oil or antifreeze. Accordingly, when power is supplied to the electric heating wire 110, heat is generated from the electric heating wire 110, and the generated heat heats the heating fluid. This heated fluid will dissipate heat to the outside of the tube.

The heat transfer tube 100 is arranged in the same shape as the hot water pipe of the boiler and is arranged on the bottom surface of the room or the living room and embedded therein. The reverse heat transfer tube 200 having both ends exposed on the predetermined lengthwise surface, .

At this time, it is preferable that the electric hot wire 110 inserted into the tube is inserted from one end of the tube, U-shaped in the vicinity of the other end, and then escapes to the other end. In this case, if the extension line 120 of the electromagnetic wave shielding line and the power supply line of the electric heating line 110 are pulled out to the same end of the tube, the sealing operation becomes difficult. Because. However, it is also possible, but not limited, that both ends of the electric hot wire 110 escape to both ends of the tube.

At both ends of the heat transfer tube 100, two downward ends of the three ends of the reverse Y-type circulation pipe 200 are connected to each other. A method selected from known pipe coupling methods may be utilized for coupling between the heat transfer tube 100 and the end portion of the reverse Y-type circulation pipe 200, And this extension hose may be communicatively coupled to one end of the reverse Y-shaped circulation pipe 200 or an outer peripheral side of the opposite end in the direction of the end. The method of exposing the extension of the electric heating wire 110 or the electric heating wire 110 and the extension line 120 of the electromagnetic wave shielding wire to the outside from the coupling point of the heat transfer tube 100 and the reverse Y- It can be appropriately selected from conventional sealing methods.

On the other hand, a large amount of electromagnetic wave is generated in the heat transfer tube 100 when a current flows through the electric heating line 110. An electromagnetic wave shielding film and a shielding line are provided to enclose the electric heating wire 110 from the outside of the electric heating wire 110 in order to block the electromagnetic wave. An electromagnetic wave shielding line may be a shield cable or the like, and an extension line is connected to an external grounding line.

The inverse Y-shaped circulation pipe 200 spaced from the bottom surface and disposed on the wall provides a circulation path for circulating the oil in the heat transfer tube 100. When the thermal oil in the heat transfer tube 100 is thermally expanded The pressure of the heat transfer tube 100 may be corrected so that the tube of the heat transfer tube 100 is not damaged or the auxiliary tube 400 may be communicated with the heat transfer tube 100 so that the air in the heat transfer tube 100 may be removed.

For this, the reverse Y-shaped circulation pipe 200 is formed in the shape of a pipe branched in three branches, and the two ends are connected to both ends of the heat transfer tube 100 so that the heat transfer fluid in the heat transfer tube 100 is circulated The two ends of the heat transfer tube 100 connected to the heat transfer tube 100 are located below the bifurcation and the other end located above the bifurcation is positioned below the auxiliary tank 400 Respectively. That is, the upper pipe is connected to the auxiliary tank 400 and the lower pipe is connected to both ends of the heat transfer tube 100, respectively, among the three branched pipes branched so as to communicate with each other.

The reverse Y-shaped circulation pipe 200 communicates between one end and the other end of the heat transfer tube 100 so as to have a circulation structure. When the heat transfer tube 100 is heated by the power supplied to the heat transfer tube 100, The flow of the oil into the auxiliary tank 400 through the inverse Y-shaped circulation pipe 200 increases the water level of the auxiliary tank 400, thereby preventing breakage of the heat transfer tube 100.

On the other hand, when a heat insulating material such as a carpet or a quilt is placed on the upper surface of the floor where the heat transfer tube 100 is embedded, heat may accumulate at the corresponding point and the temperature may unintentionally rise. In order to prevent such a case and to supply uniform heat to the entire bottom surface where the heat transfer tube 100 is embedded, in the present invention, the heat emitted from the heat transfer tube 100 is sensed at a plurality of positions of the embedded heat transfer tube 100 A temperature sensor is provided.

Therefore, the control unit controls the amount of current supplied to the electric hot wire 110 of the heat transfer tube 100, the power supply time, and the like on the basis of the temperature value input from the temperature sensors. At this time, The temperature of the heat transfer tube 100 is circulated to equalize the temperature. To this end, the reverse Y-type circulation pipe 200 is further provided with a circulation pump.

The circulation motor 300 located on the wall spaced from the bottom surface serves to circulate the oil in the heat transfer tube 100 and is mounted on the reverse Y-type circulation pipe 200 for this purpose. Here, the means for mounting on the inverse Y-shaped circulation pipe 200 means that one end of the reverse Y-type circulation pipe 200 is provided on the inlet side of the circulation motor 300 as two pieces and two pieces are connected to the circulation motor 300 And the connecting portion is connected to the inlet side and the draw-out side.

The circulating motor 300 is mounted in the direction of one end of the two ends connected to the heat transfer tube 100 of the reverse Y type circulation pipe 200 and transfers the heat transfer fluid to the heat transfer tube 100 downward . Therefore, when the circulating motor 300 is driven, the movement of the oil in the reverse Y-shaped circulation pipe 200 is elevated from one end of the heat transfer tube 100 toward the branch point of the reverse Y-shaped circulation pipe 200, And is drawn into the other end of the heat transfer tube 100 via the circulation motor 300. [

The reason why the circulating motor 300 is disposed below the bifurcation point of the reverse Y-type circulation pipe 200 is to remove air moving through the heat transfer tube 100. The heat transfer tube 100 is basically constructed so as not to allow air to flow therethrough, and the air is also removed at the completion of the heat treatment. However, the minute bubbles in the heat oil repeatedly expand and contract, As they move, they come together and flow in droplets. Therefore, the air is not a problem unless the fluid is moved by the circulating motor.

When the air flows through the heat transfer tube 100 and flows into the circulation motor 300 along with the movement of the oil, the impeller of the circulation motor 300 can not push the oil, and is idle. In this case, the heat oil is not circulated and the temperature deviation is increased on the floor where the heat transfer tube 100 is embedded. Further, when the circulation motor 300 is idle, much noise and vibration are generated in the circulation motor 300. The circulating motor 300 of the present invention is located in the wall 500 and is located at a very close distance from the person residing in the room and the vibration and noise of the circulating motor can cause a great inconvenience to the resident.

Therefore, in the present invention, the air sensor 310 is provided to sense the air when the air is drawn into the circulation motor 300 and to exclude the air on the circulation path of the fruit oil. The air detection sensor 310 is provided on one side of the reverse Y-shaped circulation pipe 200 equipped with the circulation motor 300 or on the circulation motor 300 to sense the vibration of the circulation motor 300.

When the air is drawn into the circulating motor 300, the circulating motor 300 idles and generates a lot of vibration. The control unit controls the driving of the circulating motor 300 when the vibration value measured from the air detecting sensor 310 is equal to or higher than the set value Stop.

When the driving of the circulating motor 300 is stopped, the air that has been drawn into the circulating motor 300 is raised by the buoyant force and is raised to the auxiliary tank 400 through the turning point of the reverse Y- As the air is received in the auxiliary tank 400, the oil is transferred from the auxiliary tank 400 to the inverted Y-shaped circulation pipe 200. Then, the control unit restarts the circulation pump after the set time, and the circulation pump again circulates the fuel oil.

The auxiliary tank 400 serves to supply the heating oil to the heat transfer tube 100 through the reverse Y-type circulation pipe 200 or to receive the thermal oil when the thermal oil in the heat transfer tube 100 thermally expands to correct the pressure And is connected to the other end located above the branch point of the inverse Y-shaped circulation pipe 200 for this purpose. The auxiliary tank 400 may be formed of a transparent or semitransparent material to easily identify the level of the oil from the outside, but is not limited thereto.

The control unit controls the amount and time of the electric current supplied to the electric heating wire 110 of the heat transfer tube 100 and the driving of the circulation motor 300. For this purpose, the control unit controls the reverse Y-type circulation pipe 200, Or may be installed on one side of the wall body 500 and connected to the respective components through a separate control line.

The control unit supplies current to the electric hot wire 110 of the heat transfer tube 100 so that the temperature value measured from the temperature sensor reaches the user-set temperature, and when the deviation is equal to or higher than the set value, The motor 300 is driven to circulate the oil in the heat transfer tube 100.

At this time, when the vibration value measured from the air detection sensor 310 is equal to or higher than the preset value, it is determined that air is introduced into the circulation motor 300, the driving of the circulation motor 300 is stopped, As shown in FIG. After the set time has elapsed, the circulating motor 300 is driven again so that the fruit oil can be circulated.

Meanwhile, when the auxiliary tank 400, the reverse Y-type circulation pipe 200, the circulation motor 300, the air sensor 310, and the heat transfer tube 100 exposed to the ground are exposed to the outside, It is preferable to dispose it on the depressed inlet portion 510 of the wall 500 because there is a risk of being damaged by an impact or the like. The cover 520 is further provided with a cover 520 for sealing the inlet 510 of the wall 500 from the outside and a soundproofing material 521 Respectively.

In the present invention having the above-described constitution, the heat transfer tube 100 is circulated by the reverse Y-type circulation pipe 200, and the heat transfer fluid is circulated by the circulation motor 300 so that uniform heat generation There is a possible effect.

In addition, since the circulating motor 300 is provided in the direction of the lower end of the reverse Y-shaped circulation pipe 200 and transfers the oil to the heat transfer tube 100 downwardly, the air can be easily removed .

In addition, the present invention can measure the presence or absence of air from the vibration value of the circulating motor 300, and stop the circulating motor 300 when detecting the air, so that the air can be spontaneously lifted and removed.

In the present invention, since the temperature sensor is provided at a plurality of locations in the heat transfer tube 100, the circulation motor 300 is driven only when the temperature deviation between the temperature sensors is equal to or greater than the set value, There is an effect that is not necessary.

In addition, the present invention has an effect of preventing electromagnetic waves from being lost to the outside by providing an electromagnetic wave shielding line for shielding the electromagnetic wave by wrapping the electric heating line 110.

The sound insulation material 521 is attached to the cover 520 which seals the inlet 510 of the wall 500 so that the sound insulation material 521 There is an effect that the noise due to the significant circulation can be reduced.
