Description

TECHNICAL FIELD [0001] The present invention relates to a thermoelectric module using a fuel gas as a heat absorbing medium, and a gas heating device which converts a part of the gas combustion heat into an LED lamp driving power by using the thermoelectric module. BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] HEAT OF GAS COMBUSTION IS APPLIED TO LIGHT LED LAMPS MOUNTED ON THE GAS HEATER BY USING THE THERMOELECTRIC MODULE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a gas heating apparatus that warms the surroundings by radiant heat generated when LNG or LPG is burned. Particularly, (Heat absorbing medium) of a thermoelectric element, thereby improving the heat exchange efficiency (power generation efficiency) simply and effectively. In the present invention, the electricity produced by the thermoelectric element can be used for illuminating decorative, illuminating or safety LED lamps mounted around the gas heater.

The Seebeck Effect is the principle that a difference in voltage (electromotive force) occurs due to the flow of energy (heat) in a conductor even though no current is applied to the conductor from the outside, that is, a thermoelectric effect ). The difference in temperature causes a difference in the electromotive force between the two ends of the conductor. On the other hand, the Peltier effect, in which both ends of two different conductor metals are welded to make a closed circuit, and current flows through this circuit, the temperature of the end portions of the both joints are different from each other. The thermoelectric (thermoelectric) sensor, which measures the magnitude of the electromotive force between conductors and can estimate the temperature difference across the conductor, is an example of a typical industrial application of the whitening effect, Examples of the latter include a heating and air-conditioning apparatus for a vehicle using a vehicle battery, a vehicle seat heating apparatus, or a small-sized refrigerator for a vehicle.

The present invention relates to a gas heater for burning a liquefied natural gas or liquefied petroleum gas such as LNG or LPG in the winter or outside in winter and directly heating the surrounding by the combustion heat, Lighting or safety LED lamp mounted on the periphery of a gas heater. The present invention relates to an apparatus for lighting a decorative lamp, an illumination lamp, or a safety LED lamp mounted on the periphery of a gas heater, The thermoelectric element for power generation used in the invention is a publicly known white bag element.

An example of an invention relating to the conventional conversion of combustion heat or waste heat to electricity by the whitening effect is a heater having a power generating function according to Korean Patent No. 10-0712960 as shown in Fig. This technology aims at improving the efficiency of combustion energy by ultimately generating and recycling by using the waste heat that is consumed at the time of operating the stove and the heater. In this case, the heat collecting plate which absorbs heat and collects heat at the upper part of the hearth and heater And a part of the waste heat such as the stove is converted into electricity and the other heat is dissipated through the heat dissipating plate by combining the heat conducting element for power generation with the heat collecting plate and the heat dissipating heat dissipating plate. Lt; / RTI > The heat dissipation block 30-1, the heat dissipation plate 30, and the cooling fan 40 are formed in this order so that the thermoelectric element 10, the heat dissipation block 30-1, The device 10 has a power generating function using a thermoelectric element 10 that induces a temperature difference between both ends to generate direct current electricity and supplies the direct current electricity through the direct current power supply control device 50 as electricity of stable voltage Heater is presented.

Although the heater having the power generation function according to this Korean Patent No. 10-0712960 uses waste heat in a heater such as a hearth or heater, since the waste heat is also a part of the heat of combustion, This can be said to belong to the same category as the invention.

However, the present invention is not a technique for improving the thermal efficiency (combustion efficiency) at the time of combustion simply as it is well known from the above description, but the combustion heat at the initial stage of combustion, which is not the combustion waste heat, is actively taken out directly, And is a temperature difference maximization technique that can efficiently obtain electromotive force without using a heat transfer element (heat exchange) promoting element, which is generally installed outwardly, such as a heat dissipation block, a heat sink, and a cooling fan . Therefore, the present invention differs from the prior art in that it is an art relating to an efficient heat exchange structure with respect to a cheek-element, and in particular, by using the low-temperature fuel gas itself as a low-temperature heat absorbing medium for a cheek- Which is different from the above-mentioned Korean Patent No. 10-0712960.

Further, another heating device related to the conversion of combustion heat into electricity in the conventional heating device is a heating device according to Japanese Patent Application Laid-Open No. 2001-296036 as shown in Fig. The present invention relates to a heating apparatus for circulating a heat medium (for example, water) heat-exchanged by combustion heat with a heat dissipating means (for example, a radiator) so as to reduce unnecessary consumption of the circulating pump operating battery for the heat (water) Water) at a high temperature. This technique is a heating method in which the heat 2 is heated by the combustion heating device 9 that generates heat by the oxidation reaction between the fuel gas and the air and the heat is circulated in the heat passage 19 formed in the heat dissipating means 17 The power source of the control unit 7 is divided into the thermoelectric conversion unit 12 and the battery unit 13 according to the voltage generated by the thermoelectric conversion unit 12 and the control unit 7 Is driven only by the power source of the battery 13.

Also, as shown in Fig. 11, in a heating apparatus according to Japanese Laid-Open Patent Application No. 2001-90962, similarly to the conventional heating apparatus using the thermoelectric power of the thermoelectric element as the driving source of the motor pump, the change in the output of the combustor, A heat generating part 23 for generating combustion heat and a heat dissipating part for dissipating heat generated in the heat generating part 23 (for example, And a circulation pump 16 for circulating the heat between the heat generating portion and the heat dissipating portion between the heat generating portion and the heat dissipating portion. The heat energy generated in the thermoelectric element 19 is supplied to the motor 17 of the circulating pump, (22) so that the rotation speed of the motor is kept constant regardless of the magnitude of the thermoelectric power generated by the thermoelectric element (19), thereby stabilizing the operation Lt; / RTI >

The above-mentioned two Japanese Patent Laid-open patent applications are also directed to a technique of using electric power obtained by converting a part of combustion heat by a thermoelectric power, as a pump driving power source for circulating the heat in a heating device circulating the water (heat) The present invention relates to a technology for effectively and stably ensuring electric power as a driving power source for a motor that circulates only a heat (e.g., water) to a heat radiating section. The present invention differs from the present invention in that the basic condition or configuration of the heating device is different from that of the present invention in which the combustion radiant heat during gas combustion is directly heated around the heater, The efficiency of electricity generation in converting electric energy into electric energy, that is, (Low heat source) of the fuel gas is used in order to obtain a large power of the fuel gas.

Since the electromotive force of the thermoelectric element due to the whitening effect increases as the temperature difference between the both ends of the thermoelectric element increases, the larger the temperature difference between the two heat sources (high heat source and low heat source) It is advantageous. In order to lower the temperature on the low-temperature side, the present invention does not adopt an outwardly protruding configuration such as a heat-dissipating fin or a cooling fan, which has been conventionally used for dissipating heat into the air at room temperature. The low temperature fuel gas itself, So that a high electromotive force of the device can be obtained by an extremely simple and efficient internal heat exchange structure.

On the other hand, in the case of heating devices that use gas as a heat source, such as gas heating devices, it is regulated so that external electric power can not be used in the gas heating device under the current domestic regulations in consideration of safety of use. For this reason, it is most advantageous and desirable that the gas burning heating apparatus is used in a predetermined case where a small amount of electricity is required, and a method of making and using electricity by itself using the thermoelectric effect as in the above-described prior art.

Since the invention is a gas-burning radiant heating device which directly surrounds the gas combustion heat, the frame of the heater, which is directly exposed to the radiant heat, is likely to overheat, so that the hands of those who are surrounded by heaters When the face, arm or the like touches the overheated frame, the image is likely to be instantaneously photographed. Further, in the case where the gas heating apparatus according to the present invention is used in a place without illumination at night, especially outdoors, and then the gas is closed and no further combustion is performed, even if the light due to the gas combustion flame is lost, The superheating temperature further increases the risk of burns as described above.

Further, in the construction of the gas combustion radiation heating apparatus in which the gas combustion heat is directly radiated to the surroundings and the surroundings are heated, the combustion flame of the gas is prevented from directly touching the person and the radiant heat is dispersed evenly, When a gas heating apparatus using a reinforced glass tube (combustion tube) having a predetermined diameter and a height extending vertically and vertically in a vertical direction is used in a state of being wrapped around a combustion nozzle at a lower portion thereof, Or a plurality of supporting frames extending in the longitudinal direction around the reinforced glass tube to vertically set the reinforced glass tube, a plurality of supporting frames are provided at predetermined positions, for example, on the supporting frame in the longitudinal direction thereof Accordingly, the meaning or design of indicating prohibition or safety It is very useful if a thermoelectric element capable of efficiently driving an LED lamp for such a purpose is developed.
