Description

Heating pipe {Heating pipe}

The present invention relates to a heating pipe, more specifically, to evenly heat a large indoor space, such as a plastic house, eco-friendly by not using raw materials that pollute the air, and maximize the heating efficiency while dramatically reducing the cost of raw materials It relates to a heating pipe that can be made.

Conventionally, a hot air fan is mainly used as a heating means for heating a large indoor space such as a vinyl house. Hot air heaters are usually heated in such a way that the heat generated by burning oil or gas is ventilated into a room using a large blower fan.

However, the hot air blower as described above is difficult to heat the entire inside of the plastic house at a uniform temperature, thereby lowering the heating efficiency. In addition, harmful gases are generated in the process of burning fuel such as petroleum and gas, which causes problems such as inhibiting the growth of crops and causing respiratory failure of the human body. In addition, the price continues to rise as fuels such as oil and gas are gradually exhausted, and enormous fuel costs are required for heating. Therefore, heating a plastic house using a hot air blower in a farmhouse is a significant economic burden. It is becoming.

On the other hand, a heating method is also disclosed in which heating water pipes are installed in various places of a plastic house using a boiler. However, by using fuel such as oil or gas to operate the boiler, the damage and economic burden caused by harmful gases are still maintained. It exists. In addition, since the temperature of the heating water is not high, there is a problem in that the heating efficiency is greatly reduced to be used for heating the atmosphere inside the plastic house.

The present invention is to solve the above problems, the purpose of the present invention is to use a pipe to heat the large indoor space, such as a plastic house can be heated to an even temperature, and do not cause air pollution using electrical energy Therefore, it is eco-friendly and provides a heating pipe that can maximize heating efficiency with a small raw material cost by increasing the contact area with the atmosphere while heating the pipe to a high temperature.

According to the present invention, the bone 10 is filled with the corrugated pipe 15, the heating wire 25 passed through the corrugated pipe 15 and covered by the insulator 20, and filled inside the corrugated pipe 15 There is provided a heating pipe, which comprises a heat medium 30 which transfers heat generated from the heating wire 25 to the inner wall surface of the corrugated pipe 15.

According to another feature of the present invention, the insulator 20 is provided with a heating pipe, characterized in that formed of silicon or Teflon material.

Hereinafter, described with reference to the accompanying drawings, preferred embodiments of the present invention is as follows. 1 is a cross-sectional view showing a heating pipe according to the present invention, Figure 2 is a state diagram according to an embodiment of the present invention, Figure 3 is a perspective view showing an example of the present invention applied to a plastic house.

Referring to this, the heating pipe passes through the heating wire 25 coated by the insulator 20 inside the corrugated pipe 15, and transfers the heat of the heating wire 25 to the inner wall of the corrugated pipe 15 inside the corrugated pipe 15. The heating medium 30 to be delivered is filled.

Preferably, the insulator 20 is made of silicon or Teflon material.

Referring to FIG. 1, the corrugated pipe 15 is formed such that the valleys 10 and the peaks 11 are alternately disposed along the longitudinal direction in order to widen the contact area with the atmosphere. Preferably, the corrugated pipe 15 is formed of an aluminum material having excellent thermal conductivity and excellent workability. The heating wire 25 covered by the insulator 20 passes through the corrugated pipe 15. As the heating wire 25, a copper steel wire is adopted. The heating wire 25 generates heat by resistance heat when a current is applied from a power supply source (not shown). In order to prevent the heating wire 25 from being grounded to the inner wall surface of the corrugated pipe 15, an insulator 20 is coated on the outside of the heating wire 25. At this time, as the insulator 20, a silicon or Teflon material having good heat resistance to withstand high heat is selected. In addition to the insulator 20, an alumina-based or ceramic-based resin having excellent heat resistance and excellent thermal conductivity may be selected. And, inside the corrugated pipe 15 is filled with a heat medium 30 for transferring the heat generated from the heating wire 25 to the inner wall surface of the corrugated pipe 15. Preferably, as the heat medium 30, oils having a high boiling point, low vapor pressure, and good fluidity are adopted. The heat medium 30 may be supplied from a separate tank (not shown), and may form and fill a closed space in the corrugated pipe 15. In order to ensure the fluidity of the heat medium 30, it is preferable that the heat medium 30 is not fully filled in the corrugated pipe 15.

Figure 2 is a state diagram showing an embodiment of the present invention, Figure 3 shows an example of the present invention applied to the vinyl house, with reference to this embodiment of the present invention will be described as follows.

First, as shown in FIG. 2, the heating pipe of the present invention is branched from a plurality of rows of pipes in the branch pipe 35, and is disposed in a loading place of a desired indoor space for heating. In addition, the heating pipe of the present invention may be provided as a branch pipe 35, an elbow pipe, a straight pipe, a curved pipe, and the like, and each pipe may be coupled by the connector 40. In the embodiment of Figure 3 the present invention is applied for heating of the plastic house. In this case, the heating pipe of the present invention is disposed along the edge of the inside of the vinyl house, and is fixed by a separate fastening means 50 to the column 45 inside the vinyl house. The corrugated pipe 15 disposed in the loading place in the plastic house may heat the inside of the plastic house at a uniform temperature, thereby helping to evenly grow the crop. In addition, since heating is performed using electric energy, unlike the conventional heating method using fuel such as oil or gas, there is an advantage that does not harm the crops or the human body without generating harmful gas. In addition, while using electrical energy relatively inexpensive compared to conventional fuels such as oil or gas, by using the corrugated pipe 15 to increase the contact area between the outer peripheral surface of the pipe and the atmosphere, it is possible to maximize the heating efficiency with a small raw material cost There is an advantage.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

As described above, according to the present invention, the pipe is placed in a suitable place to heat a large indoor space such as a plastic house at an even temperature, and the heat medium filled inside the pipe transfers the resistance heat of the heating wire to the inner wall of the pipe. It is environmentally friendly and does not generate harmful gas, and can provide a heating pipe that can maximize heating efficiency by widening the contact area with the atmosphere by using a corrugated pipe.
