Welcome to TEC Science Classroom! In this issue, we will give a detailed introduction to the structure, advantages and classic application scenarios of micro thermoelectric coolers.   What is a micro thermoelectric cooler? A micro-thermoelectric cooler is a small temperature control device based on the thermoelectric effect that can achieve precise heating or cooling functions. It is suitable for small electronic devices with limited space and extremely high temperature control requirements. Although the micro thermoelectric cooler is small in size, its structure is not simple. It mainly consists of two key parts:   1. Thermocouple pair (PN junction) The basic unit of TEC is a thermocouple pair composed of N-type and P-type semiconductor materials. When direct current passes through, the electrons in the N-type semiconductor and the holes in the P-type s...

Welcome to TEC Science Classroom! In this issue, we will introduce several common heat dissipation methods of thermoelectric coolers (TECs). Why do thermoelectric coolers need heat dissipation? Maybe you are curious, isn't the thermoelectric cooler used for cooling? Why is heat dissipation needed? This is closely related to its application principle: Thermoelectric coolers transfer heat through the Peltier Effect. When current passes through the junction of two different conductors, heat is absorbed or released. One side of the cooling fin becomes colder and the other side becomes hotter. In order to ensure the cooling effect, the heat on the hot side must be effectively dissipated, otherwise the heat accumulation will affect the cooling efficiency and even damage the equipment. Therefore, in the development process of thermal design, we first nee...

1. What is TEC reliability testing? TEC reliability testing refers to a testing method that comprehensively evaluates thermoelectric semiconductor cooling products by simulating actual usage conditions and environments. Its main purpose is to ensure that TEC products can operate stably and for a long time under various actual environmental conditions and meet the expected performance requirements.Through reliability testing, companies can discover potential product defects in advance and make timely improvements and optimizations, thereby improving product reliability and enhancing their market competitiveness.   2. What does reliability testing include? 1. Environmental adaptability test Including temperature testing (high temperature, low temperature, temperature cycle), humidity testing, vibration testing and shock testing ; this test is us...

TEC refrigeration clothing (air-conditioned clothing/water-cooled clothing) is a special type of clothing that cools the human body in high-temperature environments. It achieves this function through an internal cooling system. The semiconductor cooling sheet is the key component in its cooling system. Next, this article will focus on introducing the application principles, advantageous features and application scenarios of this type of special clothing.   1. Application of TEC Refrigeration Sheets in Air-conditioned Clothing Air-conditioned clothing refers to garments that cool the human body surface through air circulation and semiconductor refrigeration technology. Its built-in refrigeration system is composed of TEC refrigeration plates, temperature control components, fans and other parts. one.TEC refrigeration sheetThe refrigeration plate, as the core co...

Summer is almost here. In today's high temperature has become a global challenge, people's demand for cooling equipment is no longer limited to "use", but the pursuit of "easy to use, healthy and sustainable". However, traditional fans are limited by size, energy consumption and noise, and it is difficult to meet the cooling demand in mobile scenarios. The emergence of TEC fans has brought more high-quality and reliable cooling options for people.   How TEC fans work The working principle of the semiconductor refrigeration sheet is based on the Peltier effect (see TEC science Lesson # 1) : When a direct current flows through a module composed of semiconductor materials such as bismuth telluride, heat is rapidly transferred from the cold end to the hot end, creating a significant temperature difference. This process does not require compressors, coolers or mechanic...

San Francisco driverless TAXI first experience With the popularity of driverless technology around the world, many countries such as the United States, the United Kingdom, South Korea, and Singapore have begun to try to provide driverless taxi services in different pilots.Today, our colleagues came to San Francisco, USA, where they completed their first experience of driverless TAXI. First, we booked the ride through the mobile App. A few minutes later, the reserved car arrives at the designated place on time. We can see that the exterior body is equipped with advanced sensor devices, which are key components for environmental awareness and safe driving.Then, we still open the door through the App. After boarding the car, the central control screen displays the welcome message and itinerary overview, just click the "Start itinerary" button on the touch scr...
