ATI high-temperature TEC modules are rated to 200 °C surface temperature (vs 125 °C) for AI data center GPU and high-power IC cooling — about 2× the heat-sink-to-ambient driving force at 25 °C ambient and roughly +30% theoretical ΔTmax, letting a smaller, quieter heat sink carry the same heat load....(more)

Piezoelectric materials vs. SMA Piezoelectric materials are crystalline materials that generate a voltage at the both ends when pressure is applied to them to deform the surface; the most important characteristic is the piezoelectric effect, including the piezoelectric effect and the inverse piezoelectric effect. Piezoelectric effect refers to the application of a force to the piezoelectric material for deforming the surface of the piezoelectric material, thus forming charges at both ends of the...(more)
As shown in the fig1pictures below, there are little few appearance differences between TEC and TEG, but their principles and applications are not the same. Fig 1. The photo of TEC and TEG Based on semiconductor materials, a thermoelectric cooler (TEC) can be used as an electronic component of a small heat pump. Through by adding a little low DC voltage to both ends of TEC, heat quantity will flow from one end to the other, and at the same time, the temperature of one end will decrease and the o...(more)
The common specifications voltage of LED lights are 12V and 24V, and one team of 12V LED light consists of three pcs LEDs, while24VLED light is made up of six pcs LEDs. Once, some customer requested to reduce the power supply voltage, but h...(more)
