Embodiment Construction

[0009] In the accompanying drawings, utilize a thermal insulation shell 2 with door 1, its inner wall 3 is made of aluminum material with good thermal conductivity, the semiconductor refrigeration sheet 8 is contacted with the inner wall 3 through the heat spreader 7 (aluminum), the semiconductor The other side of the refrigerating sheet 8 is in thermal contact with the radiator 9, and the outside of the radiator 9 has an external cooling fan 10, which forms a semiconductor refrigerator. In order to measure the refrigerating capacity of the semiconductor refrigerator, a heating electric heating wire 5 is installed inside again. In order to realize the instant balance of the internal temperature, a cooling fan 4 inside the machine is also installed near the electric heater. A temperature sensor 6 is installed and connected to an external digital thermometer 16 .

[0010] The heating wire 5 is connected in series with the temperature difference power generation overheat protecto...

Abstract

The invention discloses a semiconductor refrigeration thermo-electric generation experimental instrument comprising a semiconductor refrigerator and a main machine. The semiconductor refrigerator is internally provided with electric heating wires, a thermometer, an in-machine cooling fan and an overheat protector, wherein all parts in the semiconductor refrigerator are smartly combined with all unit circuits in the main machine, conversion switches, and the like to form a physical experimental instrument capable of carrying out quantitative experimental projects, such as research on a semiconductor refrigeration coefficient, research on a thermo-electric generation rule, measurement of the internal resistance of a thermo-electric power supply, and the like and fill the gap of the prior art. The invention has the advantages of convenient and reliable use and high performance price ratio, can guide university students to research environment-friendly refrigeration and environment-friendly generation and cultivate a concept of researching new energy and can be used in common physical experiments, modern physical experiments and college physical experiment courses in colleges and universities or used as a physical experiment demonstration instrument.

Description

technical field [0001] The invention relates to a physical experiment instrument, in particular to a semiconductor refrigeration thermoelectric power generation experiment instrument. Background technique [0002] Semiconductor refrigeration has the advantages of small size, light weight, no mechanical sliding parts, no noise, green and fluorine-free, long service life, convenient and precise cooling capacity control, etc. It is used in some limited spaces, high reliability requirements, and no refrigerant pollution. Occasions (such as military, medical, industrial, testing, high-end hotels, laboratories, etc.). Its theory is based on electromagnetism and semiconductor theory in physics. Thermoelectric power generation is a green power generation mode. There are temperature differences everywhere in nature. However, thermoelectric power generation has not been used by human beings and needs further development and research. It can be seen that the application and research ...
