High voltage power supply is designed for achieving DC-DC conversion from low voltage to high voltage. It has been widelyused in industry, agriculture, national defense, scientific research and many other fields, such as X-ray machine high voltage power supply, laser high voltage power supply, particles injection high voltage power supply in semiconductor technology, physical vapor phase deposition high voltage power supply, and nanolithography high voltage power supplyetc.(more)

With the development of LED technology, more and more people like using desk lamps made of LED. LED lighting features high energy saving, environment protection, high reliability and long service lifetime. However, LED lamp with single function can’t meet people’s requirements along witheconomic and social development. So our company (ATI) has released a new LED desk lamp with multifunction, as shown in Figure 1.(more)

Super kits enclosure SK200 is a newly developed enclosure products, which contains 200 individual compartment. As you may know, we have a very popular kits product, SK128B, sold over 50,000pcs with zero return. This new SK200 is upgraded from SK128B, with better performance and larger capacity.(more)

New SMT resistor kit is the upgraded from our existing resistor kit. This resistor kit is based on our newly developed SMT component enclosure SK200, which has 200 individual lidded compartments for enclosing various SMT components.(more)

Although the two cooling systems comply with the same thermal dynamics, a TEC has many obvious advantages: simple structure, small volume, light weight, high reliability, long service lifetime, no noise, small power consumption, low cost and so on. What’s more, there is no need for TECs to fill chemical consumables, which the mechanical cooling method needs. Because of no moving parts, there is no wear and tear for TECs. Thus TEC is an ideal cooling method, which can gradually take the place of the mechanical cooling method when cooling many components (such as CCD).(more)

In practical applications, TEC can sustain work through continuous heat change of heat exchanger and cold and heat source. When the system works, the heat density of cold and hot ends can be up to 104W/m2, so effective operation is strongly dependent on heat transfer performance of cold and hot end. The heat dissipation of the cold end is more important than the hot end’s. Suppose the heat dissipating capacity of the cold end is q1, the heat dissipating capacity of hot end is q2 and the electric power consumption of the system is w0. After the TEC is connected to a power supply, the cold end continuously absorbs q1, which is cooling capacity. This part of the heat and electro-thermal consumption need to be dissipated from the hot end together, which can ensure the normal work of TEC and make TEC play an effective role.(more)

In this paper, the air cooling method of TEC is mainly introduced.(more)

In thermo-electric cooling system, the installation of TECs is very critical. Basic principles should be abided by during installation, or it may result in bad performance and reliability. There are a few factors to be considered in designing and installing the thermo-electric cooling system, as below.(more)

In general, selecting the size of TECs depends on the area of chips, but not bigger than that. Additionally, TEC has a certain thickness, which is put between chip and heat sink. If it is too thick, it will be hard to fix.(more)

In some specified applications, the main method is to use a special high thermal conductive epoxy resin binder. Since the coefficients of thermal expansion of the ceramics of TECs, heat sink and the cooled object, it's not recommended to use epoxy resin binder in large TECs. The detailed steps are as follows:(more)
