Welcome to TEC Science Lesson! Last week, we learned about the working principle and basic structure of the semiconductor refrigerator, and this class will continue to introduce its key parameters and performance. 1、Relevant performance parameters of thermoelectric refrigerator When choosing a semiconductor cooler, its comprehensive performance (such as cooling capacity, heat dissipation capacity, etc.) is our focus. The comprehensive performance of the semiconductor refrigerator is mainly determined by the four performance parameters of Imax, Vmax, DTmax and Qcmax. Let's take a look at what these parameters represent. ①Imax (maximum current) : the current value passing through TEC when the temperature difference ΔT between the heat releasing surface and the heat absorbing surface reaches its maximum. At this time, the heat absorption Qc of TEC is 0. I...

Hello everyone, welcome to TEC Science Class! In the first phase, we will focus on introducing the working principle and basic structure of semiconductor coolers. 1、 the working principle of semiconductor refrigerator- The Peltier effect Semiconductor refrigeration is also known as thermoelectric refrigeration or thermoelectric refrigeration, and its working principle is based on the Peltier effect in the thermoelectric effect. The Paltier effect was born in 1834. A French physicist named Peltier found that when the current flows through the contact formed by two different conductors, the contact will produce heat transfer and heat absorption phenomenon, and the size of the heat transfer or heat absorption is determined by the size of the current. This is the phenomenon of cooling and heating of semiconductors, also known as the Paltier effect. Its heat is calculated ...

On November 13, FerroTec Thermoelectric Division organized a lecture on the theme of happiness psychology in the workplace, with Mr. Dong, master of Applied Psychology from Fudan University, as the keynote speaker. At the beginning of the lecture, Teacher Dong began by talking about the three elements and importance of workplace happiness: Workplace happiness covers people's satisfaction with their work, their participation and concentration in work, and the harmony between work and personal life, which has a crucial influence on personal health, work efficiency and team atmosphere. Then, Teacher Dong threw out 20 anxiety tests to the employees present. Through the answer test, we have a deeper understanding of their own psychological conditions, but also learned some physical and mental knowledge related to anxiety. ▲ Lulu Dong, Master of Applied Psychology, F...

In recent years, with the enhancement of consumers' awareness of environmental protection and energy saving, new energy vehicles have gradually become people's first choice for car purchase. The government's strong support for new energy vehicles, including purchase subsidies, exemption from purchase tax, charging pile construction and other measures, has further promoted the market development of new energy vehicles. According to data released by Rho Motion, a market research company, from January to September 2024, the total production and sales of new energy vehicles completed 8.316 million and 8.32 million, respectively, an increase of 31.7% and 32.5%. It is expected that by the end of 2024, the production and sales scale of new energy vehicles in China is expected to reach 12 million, and the overall market penetration rate will exceed 50%.

Have you all heard of pumping lasers? Its English name is pump laser, which is a laser that uses the pump energy to stimulate the laser to amplify the medium (such as crystals, glass, gas, etc.) to produce laser emission. The pump laser is composed of laser medium, pump source, resonator, output coupler and controller, etc. It is mainly used in industrial, medical, communication, information technology and other fields, such as manufacturing micromachining, clinical treatment, optical communication, measurement and lidar. It uses a laser as a pump source and provides energy through a semiconductor laser. This energy is absorbed by the laser medium, such as ytterbium-doped fibers or crystals, and excites electrons in the medium. Through the above process, the final output of high power and high quality laser is generated.   ▲ Pump laser working principle   【980nm pump...
