Environmental protection heat generating device

Abstract

The invention relates to an environmental protection heat generating device which mainly comprises a semiconductor thermoelectric unit and a circuit unit which forms an electrical loop together with the semiconductor thermoelectric unit. The semiconductor thermoelectric unit is provided with a first ceramic layer, a second ceramic layer, a plurality of first conductors, a plurality of second conductors, a plurality of P-shaped semiconductors, a plurality of N-shaped semiconductors and a heat cutoff material layer; the first ceramic layer contacts a cold source; the second ceramic layer contacts a hot source; the first conductors and the second conductors are arranged on the first ceramic layer and the second ceramic layer at intervals and are mutually staggered; the P-shaped semiconductors and the N-shaped semiconductors are staggered and are connected among the first conductors and the second conductors correspondingly in series; the heat cutoff material layer is filled among the P-shaped semiconductors and the N-shaped semiconductors; and the P-shaped semiconductors and the N-shaped semiconductors receive the cold source and the hot source for causing a temperature difference togenerate current. In this way, the heat cutoff material layer is used for preventing heat from being transferred to the other end of the P-shaped semiconductors and the N-shaped semiconductors from one end, thereby intensifying the temperature difference and enhancing thermoelectric effect and generating efficiency.

Description

technical field [0001] The invention relates to a thermal power generation device, in particular to an environmentally friendly thermal power generation device which can generate electric energy by using temperature difference. Background technique [0002] In daily life, there are a lot of consumed energy generated, but wasted heat energy, such as: high-temperature flue gas generated by burners, waste heat emitted by factories, geothermal heat...etc. If the thermal energy can be properly utilized, it will become a renewable energy that meets the needs of environmental protection. The thermoelectric material (thermoelectric) can recover a large amount of waste heat and convert it into electric energy, and has the advantages of simple equipment, no transmission parts, low noise, no emission pollution, convenient access, safety and reliability, long life, and no maintenance, so it is widely used. The attention of advanced countries such as Japan, the United States, and Europe...

Problems solved by technology

[0005] 1. According to the foregoing, the greater the temperature difference of the thermoelectric semiconductor unit 1, the stronger the generated electric energy will be. However, since the P-type and N-type semiconductors 11 and 12 are respectively in contact with the heat source through the metal conductor 13, the thermal energy It is easy to conduct conduction from one end of the P-type and N-type semiconductors 11 and 12 to the other end, which will not only reduce the temperature difference between the P-type semiconductor 11 and the N-type semiconductor 12, but also affect the thermoelectric effect, so that the power generation efficiency is not as expected

[0006] 2. In the conventional P-type and N-type semiconductors 11 and 12, the metal powder is directly cut into particles after high-pressure stamping, and then soldered to the metal conductor 13 by soldering (melting temperature is 200° C.). Therefore, P-type and N-type semiconductors 11 and 12 are prone to loose disintegration and desoldering in a long-term high-temperature environment

[0007] This shows that the above-mentioned existing thermal power generation device obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
