The Thermoelectric Cooler is also called Semiconductor refrigeration module, Peltier, etc. . Because of there are two sides, one side absorbs heat, and the other side dissipates heat. Its effect is heat conduction. It does not produce heat by itself. So it is called Refrigeration piece or thermoelectric cooler module.(more)
But some usual semiconductor often is made up of Copper, aluminum or other metallic conductor and two pieces ceramic chip like sandwich biscuit to press something from both sides. The ceramic chip must be heat and conduction well. See the following the picture.(more)
NTC is the abbreviation of Negative Temperature Coefficient, which refers to semiconductor materials or electronic components. A glass encapsulated thermistor is a kind of NTC thermistors, which has the function of temperature compensation. And its main characteristics are high temperature resistance and humidity resistance.(more)
LED energy-saving lamp uses white light emitting diode with high brightness as a light source, which is a new generation of solid cold light source. It has many advantages such as high luminous efficiency, less power consumption, long service life and safety and environmental protection. Comparing with tube energy-saving lamps, LED lamps have high brightness, good light performance, wide voltage range and some other characteristics. Through the microcomputer controller, seven color changes of LED can be achieved. Comparing to incandescent or fluorescent lamp with low voltage, LED has obvious advantage in the respects of stability and long service life. The continuous work time of incandescent lamps is rarely more than 1000 hours; using electronic driver, the continuous work time of fluorescent lamps can be up to 8000 hours; LED trouble-free work time can reach 50000 hours.(more)
Thermalsilicone pad is a heat transfer mediumto reduce thermal contact resistance between the heat source surface and contact surface of radiator parts. In the industry, it is also called the thermal silica films, thermal conductive silicone pads, soft cooling pads and so on. As the electronic equipment continually makes more and more powerful function integrate into smaller and smaller components, the temperature increasing will lead to equipment running slowly, device fault, confined space and many other performance problems. So the temperature control has become one of the critical design challenges, that is, in the situationof framework of austerity and smaller and smaller operation space, how to effectively take away more heat produced by larger and larger unitpower.(more)
LED is the abbreviation of light emitting diode. LED is being widely used with the development of economy and technology. In this paper, I will introduce the application of LED in the aspect of indicator light in the circuits.(more)
There are many characteristics of thermal silicone pads, such as certain flexibility, excellent insulation and compressibility, natural surface tack and so on. The silicone pads are specially produced for the design proposal of transferring heat by using the gap. The thermal silicone pad can fill in gaps and transfer the heat between heating part and radiating part. At the same time, it also plays an insulation, sealing, damping effect. What’s more, the thermal silicone pads can meet the design requirements of equipment miniaturization and ultra-thin, and they have wide application range of the thickness.(more)
Light Emitting Diode (LED) is a kind of semiconductor solid light emitting device, which uses solid semiconductor chips as light emitting materials.When applying a positive voltage at its both ends, the composite of carriers in semiconductor will induce photon emission and produce light. LED can directly emit red, yellow, blue, green, green, orange, purple and white light.
There are many advantages of LED product.(more)
The thermistor is a kind of sensitive elements. According to the different temperature coefficients, it is divided into positive temperature coefficient thermistor (PTC) and negative temperature coefficient thermistor (NTC). The typical characteristic of the thermistor is sensitive to temperature, and it shows different resistant values under different temperatures. With the increase of temperature, the resistant value of PTC will be larger and with the decrease of temperature, the resistant value of NTC will be smaller. PTC and NTC both belong to semiconductor devices.(more)
