Also known as semiconductor thermoelectric module, thermoelectric device and semiconductor thermoelectric chip, it is an electronic device composed of thermal conductive and insulating material substrate, such as copper-clad ceramic substrate, semiconductor grain, wire and other semiconductor thermoelectric device fingers, which uses the thermoelectric effect of semiconductor materials to realize the direct mutual conversion of electric energy and heat energy. According to the direction of thermoelectric conversion, It can be divided into semiconductor thermoelectric refrigeration devices and semiconductor thermoelectric power generation devices.
Thermoelectric cooling modules, also known as Tec, thermoelectric refrigeration device, semiconductor thermoelectric refrigeration component, refrigeration chip and semiconductor thermoelectric refrigeration chip, is a kind of semiconductor thermoelectric refrigeration device, which refers to an electronic device that uses the Peltier effect of semiconductor materials to realize refrigeration or heating. Tec products of the company include single-stage thermoelectric refrigeration devices, micro thermoelectric refrigeration devices, multi-stage thermoelectric refrigeration devices and other types.
Thermoelectric power generator, also known as TEG, thermoelectric device and semi-semiconductor thermoelectric device, is an electronic device that uses the Seebeck effect of semiconductor materials to realize power generation.
Peltier effect, first discovered by Peltier, a Frenchman, is a phenomenon that heat will be absorbed or released at the node when direct current passes through the circuit composed of two different conductive materials through Peltier effect.
Seebeck effect was first discovered by German scientist zebeck in 1821. Zebeck effect is the inverse process of Peltier effect. When two different conductive materials form a circuit, zebeck effect heats one node and keeps the other node low temperature. In the circuit, electromotive force is generated due to the temperature difference between the two nodes of conductive materials Phenomenon of loop current.
Also known as white sheet, it refers to the ceramic substrate with an alumina content of 96% and a thickness of about 0.25mm to 1.2mm. 96% alumina ceramic substrate has high thermal conductivity, good insulation strength, high pressure resistance, high temperature resistance and corrosion resistance. It is the basic material for making ceramic circuit boards.
Copper clad ceramic substrate is an electronic basic material made by directly sintering copper foil and copper clad sector on the surface of ceramic substrate using DBC (direct bond copper) technology. It has excellent heat cycle resistance, stable shape, high thermal conductivity, high reliability, large current capacity and high mechanical strength.
The dimensionless thermoelectric performance merit value ZT is a composite parameter obtained by calculating the physical property parameters of zebeck coefficient, conductivity and thermal conductivity ZT value index and the corresponding temperature. It is a comprehensive embodiment of the thermal and electrical characteristics of materials. The larger the ZT value of thermoelectric materials, the higher the thermoelectric conversion efficiency.
The conversion efficiency between thermal energy and electric energy is divided into power generation efficiency and refrigeration efficiency according to the different conversion directions from thermal energy to electric energy and from electric energy to hot (cold) energy. Thermoelectric conversion efficiency refers to the electrical efficiency, which is defined as the ratio of the electrical power output from the device to the load and the heat absorption power of the device, that is, the output electrical energy converted from the unit input heat energy to the load. Refrigeration efficiency is defined as the ratio of the refrigeration power of the device to the input electric power, that is, the cold energy generated by the unit electric energy.
Bismuth telluride (Bi2Te3) based thermoelectric material was found in the 1950s. This material refers to the material with excellent thermoelectric properties near room temperature. It is widely used in refrigeration and power generation near room temperature. It is the only thermoelectric material system widely commercialized in thermoelectric materials at present.
Semiconductors and holes are their own conductive mechanisms. In semiconductors, valence electrons are bound by atomic nuclei and cannot move by themselves in crystals. Free electrons and holes are valence p-type and n-type semiconductors, which are produced by changing the motion state of electrons after being excited by heat. For n-type semiconductors, the conductive mechanism is a free electron, and for p-type semiconductors, the conductive mechanism is a hole. The difference between n-type semiconductors and free electrons is that the charge is equal and the symbol is opposite.
The size index of thermoelectric refrigeration device refers to w refers to the width of refrigeration device substrate, L1 refers to the length of cold end substrate, L2 refers to the length of hot end substrate, and H refers to the height of refrigeration device.
