Description

Radiant heating device using constant temperature heater and heat pipe {A radient system using positive temperature coefficient heaters and heatpipes}

The present invention relates to a far-infrared radiant heating apparatus using electricity capable of heating with less power than conventional heating apparatuses.

The heat pipe, the constant temperature heater, and the radiant heating, which are the materials used as the main core elements in the present invention, are described in detail as follows.

Heat pipes, also called heat pipes, were manufactured by General Motors of the United States in 1942 for heat dissipation of spacecraft, but have been put into practice since the 1960s. The heat pipe is a pipe exhausted from the inside, filled with volatile liquid inside. In a heat pipe, when heat is applied to one end, the liquid evaporates and moves to the other end with thermal energy. It dissipates at the other end of the pipe and passes through it to return to its original position. Copper, stainless steel, ceramics, tungsten, etc. are used as a material of a heat pipe main body, and methanol, acetone, water, mercury, etc. are used as an internal volatile substance.

A constant temperature heater is a PTC heater, and a PTC (Positive Temperature Coefficient) heating element is a semiconducting ceramic element having a directly proportional temperature coefficient. As the temperature increases from the time of reaching the melting point to the melting point, the electrical resistance increases markedly to maintain a constant temperature, so when the PTC heating element is used, there is no need to connect bimetal, etc. In addition, regardless of the input power source can maintain a constant temperature by the Curie temperature (Curie temperature) set inside, so it is safer and more convenient than conventional ceramic heaters and excellent heat generation performance.

The types of heat transfer can be classified into heat conduction, heat convection, and heat radiation. Thermal conduction is a phenomenon in which the temperature of a high object moves to a low temperature object by the contact of two objects, and the heat convection phenomenon is relatively light, rising upward and low temperature air as the gas expands and loses density when heated. Is denser and comes down. Heat is circulated along by the flow of air molecules, and heat radiation is a phenomenon in which heat particles move directly from a hot object to a cold one without passing through an intermediate medium. The temperature is lowered by emitting light, and the low-temperature object absorbs the electromagnetic wave, and the temperature is increased.

On the other hand, far infrared radiation, which is attracting much attention in the health field, radiates far infrared rays when heat is applied, and is a material having a function of converting into thermal energy and light energy. When heat is applied to the far-infrared radiation, light energy is radiated. Radiant wavelengths are generated when heating charcoal, ocher, etc., which is widely known as a material that emits far-infrared rays. This has the effect of promoting metabolism.

Conventional electric radiators heat air to increase the concentration of dust, increase the amount of carbon dioxide in the space, and cause headaches and air pollution. In addition, in the case of a heating device using a heating wire, only the local part is heated without heating the entire space, and when used, the heating part produces a burning sensation and the non-heating part feels the cooling feeling at the same time, and the heating effect is incomplete. have. In addition, since these heating devices are based on convection heating, a large amount of heat is required in a large space. If you look at the current capacity of heating products, you need 1.5 ~ 2Kw per hour to heat 13.2㎡ (4 pyeong).

The present invention seeks to address these shortcomings and to develop a healthy and comfortable heating system. And when heating a large area hot water circulation heating requires the installation of the boiler and the heating efficiency is lower as the distance away from the boiler, the energy consumption is too much compared to the efficiency, so in the present invention heating while using a small amount of power It is to develop an economical heating system using materials and fastening technology that can effectively dissipate the required heat.

The present invention is effective in reducing the heating cost because the amount of power consumed by a radiator using a constant temperature heater and a heat pipe is small. Therefore, it can be easily installed in the place where radiant heating is needed, and excellent heat storage effect compared to the conventional heating method, it can be used as a healthy and comfortable heating device because there is no emission of components harmless to the human body.

In addition, using the patent of the present invention can maintain a space of 13.2 m 2 (4 pyeong) at all times with a power of approximately 0.3 ~ 0.5Kw.

     The present invention is a radiation radiation using a constant temperature heater and heat pipe which is improved by the inventors patented 10-0664326 (heating device using a constant temperature heater and heat pipe) and 10-0664327 (structural material using a constant temperature heater and heat pipe) It relates to a heating device.

     Accordingly, the present invention provides a constant temperature heater 20, a heat pipe 15, and a far infrared radiation material 14 in a metal case 13 to which a far infrared ray coating film 12 is applied in order to provide a radiator improved than a conventional heating apparatus. After attaching the built-in radiation radiator 10 and the radiation radiator 10 to the support plate 30, the radiation using a constant temperature heater and a heat pipe newly manufactured the mounting outer frame 40 and the safety net 50 Heating device.

     The present invention for achieving the above object will be described in detail with reference to the drawings. 1 is a perspective view showing the structure of a radiating heat sink which is a key element of the present invention, Figure 2 is a cross-sectional view showing that the radiating heat sink is a core element of the present invention attached to a support plate, Figure 3 is a heat sink and the core element of the present invention and 4 is a disassembled perspective view of a radiator-type heating apparatus using a net, and FIG. 4 is a perspective view showing an assembled state of a radiator apparatus using the present invention.

     First, the radiant heat radiating device 10, which is a core part of the present invention, as shown in FIG.

The constant temperature heater 20 attached to one end of the heat pipe 15, the heat pipe 15 and the constant temperature heater 20 are placed in the metal case 13, and the metal case 13 and the heat pipe 15 are placed in the metal case 13. The space between the) is filled with a far-infrared radiation material (14), both sides of the metal case 13 is sealed with a partition 17, one of the partitions 17 is connected to the constant temperature heater (20) The electric wire 16 is pulled out, the outside of the metal case 13 is coated with a far-infrared coating film 12 so that far-infrared rays can be radiated, the metal case 13 is a piece 19 and a piece hole 18 ) And the radiation radiator 10 is completed by attaching to the fixing plate 11 using screws.

At this time, the surface attached to the metal case 13 of the fixing plate 11 is preferably formed of a heat reflecting plate such as thin film aluminum that can reflect the heat, the opposite surface on which the metal case 13 is not attached is uretan , PE foam, PP foam, PS foam is attached to the heat insulating material is preferably insulated from the heat generated in the metal case (13).

      At this time, the constant temperature heater 20 can be implemented in a simple circuit because the temperature can be adjusted without the need for a separate bimetal. That is, since the constant temperature heater 20 has a function of automatically controlling the power without increasing the resistance value when the temperature reaches a constant temperature, it is possible to safely maintain the temperature required for heating with a relatively small amount of power. have.

       Since the constant temperature heater 20 is small within approximately 5 to 15 cm, a technique for generating a large area is required if it is to be applied to heating.

In this case, the far-infrared radiation member 14 is supplied with heat by the heat pipe 15 to have heat storage property, and has a radiant heating effect at a temperature within 60 ° C.

       When heating a large area, the heating effect is increased because the heat generating area of the surface is widened by using a plurality of radiant heat radiators 10 once regenerated. At this time, the far-infrared radiation material 14 is advantageous, such as ocher, charcoal, salt, ceramic, mica, elvan to emit far infrared rays. In addition, in order to radiate far infrared rays to the outside, the surface of the metal case 13 is preferably coated with a material that emits far infrared rays such as ceramic or a sheet impregnated with carbon, and the heat of the surface of the metal case 13 The far-infrared coating film 12 increases the far-infrared radiation effect, which enables more comfortable radiant heating.
