Description

[0001] CANDLE LIGHT GENERATOR USING THERMOELEMENT ASSEMBLY [0002]

The present invention relates to a candle generator, and more particularly, to a candle generator that generates electricity using heat generated from a candle and a whitening effect of a thermoelectric element.

The candle generator is a device that generates electricity by using the whitening effect of the thermoelectric element and the heat of the candle. The Seebeck effect is a thermoelectric phenomenon in which current flows through a closed circuit that connects two metals or two semiconductors when they produce a temperature difference between two metals or two semiconductors. There is a thermoelectric element as a semiconductor which utilizes such a whitening effect. If a temperature difference is applied to both sides of the thermoelectric element, an electromotive force is generated.

The candle generator generates heat by heating the junction of one of the thermoelectric elements with the heat of the candle and by the temperature difference between the other junction and the junction. Here, power can be supplied to the household appliances using the generated electricity.

Here, the larger the temperature difference between the upper substrate and the lower substrate of the thermoelectric element, the greater the amount of electricity generated. Theoretically, as the heat applied to the lower substrate becomes larger, the temperature difference between the upper substrate and the upper substrate becomes larger, and the electric generation efficiency becomes higher by using the temperature difference.

However, in practice, since the heat of the lower substrate is transferred to the upper substrate side and conducted, there is a limit to increase the temperature difference between the lower substrate and the upper substrate, so that the amount of electricity generated by the candle generator is insufficient. Therefore, there is a problem that extra energy is required to increase the temperature difference.

The thermoelectric module 100 includes a lower substrate 110 and a lower substrate 110. The lower substrate 110 receives the heat of the candle F through the support frame 200 and is heated to a high temperature T1, (120) is disposed at a normal temperature, the temperature of the lower substrate (120) is lower than that of the lower substrate (110).

The cool air generated at a low temperature of the upper substrate 120a is moved upward along the upper guide plate 123 curved upward in the same direction as the lower guide plate 113.

A temperature difference between the high temperature T1 of the lower substrate 110 and the lower temperature T2 of the upper substrate 120 is generated between the lower substrate 110 and the upper substrate 120 and between the intermediate substrate 140 The upper and lower n-type semiconductors 130 and 130 'and the upper and lower p-type semiconductors 130' and 130a ', which are disposed in the upper and lower n-type semiconductors 130 and 130' The generated electricity is stored in the battery 500 through the electric output lines 181 and 183 and is transmitted to the electric appliance A through the electric appliance connection lines 510 and 520 so that the electric appliance A is driven.

At this time, the thermoelectric module 100 minimizes the conduction of heat between the upper substrate 120 and the lower substrate 110 by the intermediate substrate 140 so that a large temperature difference is generated between the upper substrate 120 and the lower substrate 110 . Accordingly, it is possible to increase the amount of electricity generated in the candle generator 1, thereby generating electricity in the outdoors without using energy such as a battery to use the electric appliance.

This makes it possible to use electric devices in outdoor activities such as mountain climbing, camping, fishing, etc.

6 and 7, the candle generator 1a according to another embodiment of the present invention includes a heat-shielded skirt wall 230 at a lower portion of the support frame 200a, The heat does not move quickly to the outside, but stay inside for a long time.

Thus, the heat of the candle F can be concentrated on the thermoelectric element seating plate 210, thereby maximizing the heat transfer efficiency. Furthermore, the bottom surface of the thermoelectric element receiving plate 210 may be provided with a heat transfer trench 211 for increasing the contact area with the heat H, thereby further increasing the heat transfer efficiency.

Accordingly, the lower substrate 110 can be heated to a higher temperature T1, and the temperature difference with the upper substrate 120 can be further increased, and the amount of electricity generated can be increased.

As described above, the candle generator using the thermoelectric module according to the present invention increases the heat conduction distance between the lower substrate and the upper substrate through the intermediate substrate between the lower substrate and the upper substrate of the thermoelectric module, Increase the temperature difference.

In addition, the candle generator of the present invention can prevent heat conduction between the lower substrate and the upper substrate of the thermoelectric module, thereby increasing the temperature difference between the lower substrate and the upper substrate.

Thus, the electricity generated by the thermoelectric module can be increased to improve the efficiency of the candle generator.

Further, the candle generator according to the present invention includes a support frame for supporting the thermoelectric module, and a heat-shielded skirt wall for stagnating the heat of the candle is provided, so that the heat of the candle can be transferred to the thermoelectric module have.

Accordingly, when the heat of the candle is applied at the same time, the amount of electricity generated due to the temperature difference generated by the candle generator according to the present invention can be increased.
