Every pet owner worries about their furry friends after being away for a few days. Especially in the summer, with temperatures nearing 40 degrees Celsius, food can easily spoil, become smelly, and infested with insects. To ensure fresh and healthy food for pets left alone at home, a new thermoelectric cooling technology, the TEC Smart Feeder, has emerged.   1. Working principle of TEC smart feeder   The TEC Smart Feeder's ability to keep food fresh, like a small refrigerator, relies on semiconductor refrigeration technology. When powered on, the fins create cooling on one end and dissipate heat on the other. The cold end, attached to the bottom or side of the grain bin, cools the grain, while the hot end uses a fan to dissipate heat, maintaining a stable temperature of around 4–15°C in the storage area. This effectively creates a small, con...

1. Working principle of multi-stage thermoelectric cooler When using single-stage thermoelectric coolers to control the temperature of equipment, we sometimes find that the cooling effect is less than ideal. This is especially true for applications with high cooling requirements, such as infrared detectors and deep-sea sensors (which require temperatures below -100°C to function properly). Single-stage coolers are no longer sufficient, and multi-stage coolers are needed for deep cooling. Let's first review the working principle of a single-stage semiconductor cooler: When the cooler is energized, current flows through the semiconductor material, creating a temperature differential at the contact point. One side absorbs heat (the cold end) and the other side releases heat (the hot end), achieving the desired cooling effect. The multi-stage semiconductor refrigeration pla...

In the summer, we often experience this: turning on the fan at night can cause headaches and leg soreness, while running the air conditioner all night makes things too dry. Is there a more gentle and comfortable way to cool down? Today, let's explore a new summer cooling option that's cooler than a fan and more hydrating than air conditioning: a semiconductor water-cooled mattress.   1. Working principle of semiconductor water-cooled mattress The working principle of the semiconductor water-cooled mattress is mainly based on the Peltier Effect. In addition, it is combined with a water circulation system and temperature sensors to ultimately achieve efficient and uniform temperature regulation. 1. Semiconductor refrigeration chip achieves efficient cooling The transelectric cooler (TEC) is the core component of a semiconductor water-cooled mattress. When the mattress is...

In summer, even at 40°C (111°F), if you park your car outdoors for just one hour, the seat temperature will quickly rise to over 60°C (111°F), making it incredibly hot to sit in. Even turning on the air conditioner beforehand can hardly bring the temperature down quickly. To enhance the driving experience, FerroTec has integrated thermoelectric  cooling technology (TEC) into car seats. This precise temperature control technology automatically adjusts the seat temperature, allowing drivers and passengers to park freely even on 40°C (111°F) days.   Popularization of TEC hot and cold seats in the automotive field   In the European and American markets, CCS-equipped seats (TEC hot and cold seats) are widely used in high-end models priced over 300,000 yuan - traditional automakers such as BMW, Mercedes-Benz, and Land Ro...

1. What is a TEC cooling module? The TEC cooling module is a solid-state refrigeration device whose core component is a semiconductor refrigeration element (TEC). The working principle of the cooling module is based on the Peltier effect: through direct current drive, heat is transferred from the cold end to the hot end, achieving a cooling effect. TEC refrigeration modules usually consist of the following three parts: Cold surface contact parts: direct contact with temperature control object Semiconductor Refrigeration Chip: Core Refrigeration Component Hot surface contact components: responsible for system heat dissipation   2. Commonly used refrigeration module series TEC cooling modules are categorized into various series, including DA, DN, AA, NN, DL, AL, DD, NA, and LL, depending on the contact method between th...

The role of TEC sealing glue in TEC module Sealing is a process that applies a layer of sealing material (sealing) to the surface of electronic components or modules to provide protection and enhance performance. It is directly related to the stability, life and reliability of semiconductor refrigeration modules. The following are the four major functions of sealing in TEC modules: 1.Isolate water vapor and corrosive gases When the semiconductor refrigeration chip is working, if the cold end temperature is lower than the dew point temperature, the water vapor in the air will condense into water droplets. When water vapor or corrosive gas (such as salt in a humid environment, industrial waste gas) enters the interior of the TEC, it will cause the semiconductor material to deteriorate and the copper electrode to corrode. In severe cases, it may also cause a short circui...

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...
