The fascia gun is no longer the exclusive equipment of fitness enthusiasts. It is very practical and can help people loosen muscles and relax their body and mind in daily life. The hot and cold fascia gun we are going to introduce today is a bit special - it has a thermoelectric cooler in its body, which provides it with an additional temperature regulation technology compared to ordinary fascia guns. This also means that in addition to massage, it can also provide hot and cold compresses to various parts of the body.   1. The structure and working principle of the cold and warm fascia gun ①Power drive system The power drive system of the fascia gun includes components such as brushless motor, transmission mechanism and impact shaft. The cold and warm fascia gun usually uses a brushless DC motor (BLDC), which can reach a speed of 3000-4500 rpm, can produce a stro...

There is a medical device called PCR instrument in the hospital's laboratory, which can detect viruses, determine genetic diseases, and even be used for paternity testing. These important functions are inseparable from the small semiconductor refrigerator in its body. 1. Working principle of semiconductor refrigerator The working principle of a semiconductor refrigerator is not complicated. Imagine that its interior is like a small factory with two rows of "workers" standing side by side - one row is P-type semiconductors and the other row is N-type semiconductors, connected by a wire. When the current passes through the N-type semiconductor after power is turned on, the electrons are pushed to the cold end, absorbing heat, and the temperature of the cold end drops; in the P-type semiconductor, the electrons carry the heat to the hot end, and the temperature of the hot ...

With the rapid development of science and technology, infrared cameras, as devices that can capture infrared radiation from objects and convert them into visual images, have been widely used in security monitoring, industrial inspection, biomedicine, astronomical observation and other fields.   1.Why is it necessary to perform precise temperature control on infrared cameras? For infrared cameras (especially those working in the short-wave infrared region), the image quality is easily affected by the "dark current". The dark current of the detector in the camera, such as the common InGaAs sensor, increases sharply with the increase of temperature. Studies have shown that for every 10°C increase in temperature, dark current* will increase by about 3 times. The increase in dark current will greatly reduce the sensitivity of the camera sensor and severely compres...

Most of the common electric lunch boxes on the market now do not have a cooling function. As the weather gets hotter, the food in the lunch box will become stale in less than half a day. Is it possible to make the lunch box no longer just a "heating tool" but also have the ability to keep food fresh like a refrigerator? Based on this idea, FerroTec  has launched a smart lunch box that can both heat and cool.   1. Dual use for cooling and heating: based on semiconductor refrigeration technology The reason why this smart lunch box has the refrigeration capacity that ordinary lunch boxes do not have is that its base is equipped with a semiconductor cooling plate independently developed and manufactured by Advanced TE, which connects the upper and lower heat conduction plates and achieves precise temperature control through TEC technology. • Press the heati...

Water dispensers are indispensable small appliances in homes and offices. The core component of water dispensers, the ice tank, directly determines the cooling performance of water dispensers. A high-quality ice tank can not only cool quickly, but also ensure long-term stable operation of the equipment. However, there are some problems with the traditional ice tank solutions currently available on the market, such as complex production processes and unstable refrigeration, which may cause the ice tank to have slow cooling speed, high energy consumption, and high maintenance costs. Semiconductor refrigeration (TEC) technology effectively solves these problems and also provides a more flexible and efficient cooling solution for the ice tank. Next, this article will introduce in detail the working principle, core advantages and future development trends of semiconductor refrigerati...

Recently, FerroTec Group successfully held the second special work meeting on automation and staff reduction, comprehensively summarizing the current progress and deploying key tasks for the next stage. The meeting focused on two core topics: one is the progress of automation implementation and future planning; the other is the analysis of staff reduction work and the evaluation of the "talent bank" management mechanism.   Thermal Power Division: Steadily promote automation and continuously optimize personnel structure General Manager Ruan Wei of the Thermal Power Division reported on the progress of the current automation project and the phased results at the conference: the overall operating efficiency has been steadily improved, and the personnel structure has been continuously optimized. From 2025 to 2026, the overall planning project includes 25 types of automa...

Recently, the annual plum rain season has arrived in the south. The floor at home is wet, clothes are still not dry after a week of hanging, and even the walls are beginning to grow mold... At this time, we urgently need a dehumidification device to solve the various problems caused by "humidity". The following new dehumidification device that integrates TEC technology - semiconductor dehumidifier, is becoming a new choice for people's dehumidification. Today we will talk specifically about its principles, advantages and common application scenarios. 1. Working principle of semiconductor dehumidifier The working principle of semiconductor dehumidifiers is based on the Peltier effect (see TEC Science Classroom Issue 1 for details) : When the semiconductor dehumidifier is powered on, the current passes through the semiconductor material, forming a diff...

As people's pursuit of quality of life continues to improve, more and more families choose to use fireplaces for heating in winter. At this time, placing a small unplugged fan next to the fireplace can make the indoor warmth much higher. This unplugged fan is called a "fireplace fan", and this warming phenomenon is essentially due to "temperature difference power generation".   1. Thermoelectric power generation principle: Seebeck effect The term "thermoelectric power generation" may sound advanced at first, but it is no longer a new technology. As early as the 19th century, German physicist Thomas Johann Seebeck discovered the principle of thermoelectric power generation - the "Seebeck effect". The Seebeck effect is the first thermoelectric effect, which refers to the phenomenon that when there is a temperature difference between the junctions of two differe...

Hello everyone, today we will mainly talk about a very critical but easily overlooked topic in the new energy field: the heat dissipation problem of IGBT modules. The "Made in China 2025" issued by the State Council clearly pointed out: "We must promote the development of new energy, smart grids and other fields, and make breakthroughs in key technologies such as high-power power electronic devices." As a core component of a variety of power electronic equipment such as photovoltaic inverters, electric vehicle electronic control systems, and industrial power supplies, the performance of IGBT (insulated gate bipolar transistor) depends to a large extent on how well it dissipates heat. So what are the mainstream heat dissipation methods for IGBT modules at present? Is there a better alternative? Let’s continue looking down. ▲IGBT (Insulated Gat...

Hello everyone, today I’m going to introduce a technology combination that sounds a bit “hardcore”: thermoelectric cooler (TEC) + photodetector. What is a Photodetector? What is a semiconductor refrigerator? Why do we need to use semiconductor coolers and photodetectors together? Let’s take a look at it together next. What is a photodetector? Simply put, a photodetector is a device that converts light signals into electrical signals. You can think of it as the "eye of light", responsible for sensing the presence and intensity of light. It has a wide range of applications, including fiber optic communications, cameras, laser printers, medical imaging, satellite remote sensing, space exploration, and so on. It can be said that as long as there is light, it is almost indispensable.   Photodetectors are very "afraid of heat" Although photodetecto...
