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)

Introduction of Epoxy Resin

Epoxy resin refers to organic compounds with two or more epoxy groups, and with rare exceptions, their relative molecular mass is not high. Epoxy resin has many advantages such as good dielectric properties, mechanical properties, adhesion, corrosion resistance, etc. And its dimensional stability and manufacturability are also both good, as well as its comprehensive properties. Whats more, due to the flexibility and diversity of epoxy materials, epoxy resin almost meets all the requirements of v...(more)

TEG is the abbreviation of thermoelectric generator, which can convert heat directly into electricity, totally opposite to TEC . TEG can be used as anti-corrosion protection for oil pipeline and gas pipeline and it can also be used as a power supply for monitoring facilities. The principle of TEG The operating principle of TEG is based on Seebeck effect found by Tomac Norahh, a German physicist. In an open circuit of two different conductors, if there is temperature difference between two contac...(more)

The Brief Introduction to TEC

In 1821, Thomas Seebeck discovered when two conductors with different materials and different temperature are connected, there is current flowing in the loop However, twelve years later, J. C. Peltier discovered an opposite phenomenon, that is ,by deleting a conductor in the loop, the external current can flow through the loop, and then a temperature difference between two connecting points is appeared. This phenomenon came to be known as Peltier Effect. Owing to the limitation of material at th...(more)

The Advantages of LED Car Lights

As a fourth-generation automobile light source, LED (Light Emitting Diode) lamps have been widely used for producing many beautiful car style by car manufacturers. LED light has many advantages including no delay, energy saving, long life, low heat, seismic resistance and high color purity and it has taken place of tungsten filament lamps and halogen lamps in many fields. Although its cost is very high, LED lamp has incomparable advantages of good quality and high grade when comparing with incan...(more)
