Description

Heating device using heat medium oil and micro heating element {HEATING APPARATUS USING HEAT-MEDIUM OIL AND MICRO HEATING BODY}

The present invention uses a triple cladding tube, heat medium oil, and micro heating element to rapidly generate heat with a small heat source to maximize thermal efficiency as well as reduce power consumption, and do not have an additional device for adjusting pressure, as well as providing an oil adsorption cloth. The present invention relates to a heating apparatus using heat medium oil and a micro heating element, which can prevent overheating and disconnection of a heating wire.

The boiler with a heating wire inside the pipe is configured to heat the water inside the pipe using the electrical resistance of the heating wire installed inside the pipe.

However, water has a problem that it takes a long time to increase the temperature is heated compared to other liquids.

That is, the rate of temperature drop is slow, but on the contrary, the rate of temperature rise is slow, and at this time, there are problems that many heat sources, that is, a lot of power are consumed.

In order to solve this problem, the heating tube (Korea Utility Model Publication 1985-0001888) has been published to increase the temperature rise rate by using oil as a heat medium oil.

Such a technique has the advantage that the rate of temperature rise by the internal oil is fast, and thus, the power required to reach a certain temperature is low.

By the way, the heating devices using the electricity as described above mainly use the late-night electric power, the late-night electric charge is increased due to the recent increase in the use of the late-night electric power, the problem of having to pay an expensive electric charge even when using oil as a heat medium as described above This is what happens.

On the other hand, in such a hot water pipe boiler, the electricity must be reached to the heating wire, it is necessary to connect the heating wire and the general wire.

Here, when the heating wire is exposed to the air in the inside of the tube, the air inside the tube is heated to a high temperature, so that the pipe of the synthetic resin is deformed or burned out, which causes a problem of leakage.

Therefore, the technology of connecting the heating wire and the general wire will be called a very important technology in a boiler using a tube with a heating wire.

As a technology related to a connection device for connecting a heating wire and a general wire, the heating wire is inserted into the inside of the tube where the heating wire is installed to connect the heating wire to minimize the phenomenon that the heating cap heats the sealing cap of the connecting device and the sealing cap melts. The structure of a hot water pipe with a heating wire inserted (Korean Utility Model Publication No. 20-415173) has been disclosed.

However, since water is generally used as a heat medium oil, the above structure has a problem in that a short circuit occurs when water comes into contact with a general electric wire due to a problem in which a heating wire and a general electric wire are connected in a hot water pipe.

In addition, although the connection point was applied with a waterproofing solution, the member applying the heating wire generally did not solve the short circuit problem because the Teflon material with low adhesiveness was not generally guaranteed to be completely waterproof.

In order to reduce the risk of electric leakage, a plug with a heating wire penetrated is installed inside the connecting device, and a 'sealing device at the end of the hot water pipe with a heating wire inserted' is connected to the heating wire and the general electric wire by the plug boundary. Utility Model Publication No. 20-326909) has been published.

The above technique reduces the risk of leakage due to the above technique, but there is a problem in that a leak occurs due to a gap between the plug and the heating wire due to damage of the plug due to the temperature rise of the heating wire.

The leakage of water eventually results in a decrease in the heat medium oil inside the tube, which leads to a problem that the tube is overheated and deformed or destroyed by a heating wire exposed to air.

On the other hand, using a sealing member made of elastic silicone material to improve the sealing performance of the connection point 'hot water pipe end sealing device of the thermal medium electric boiler' (Korea Patent Publication No. 10-0517863) has been published.

Such a technique prevents leakage by using elastic properties of the sealing member.

However, due to continuous heat, a gap occurred between the sealing member and the penetrating heating wire, which caused water leakage.

The heating device using the heat medium oil and the micro heating element of the present invention is to solve the problems occurring in the prior art as described above, and the hot water pipe is formed of a triple coat pipe of polyethylene coated, aluminum coated, and polyethylene coated, and the heat medium oil is formed. By using a micro heating element inside the heat medium oil, it is intended to rapidly generate heat with a small heat source to maximize thermal efficiency and to reduce power consumption until reaching a certain temperature.

In addition, it is intended to be able to prevent overheating and disconnection of the heating wire by simply using an oil adsorption cloth inside the triple coated pipe without having an additional device for adjusting the pressure.
