Once the malfunction is eliminated and power is restored, the system will buffer the output to prevent the fuse burn-down.

Its state-of-art assembling techniques, is fully capable of producing multi-stage high power and large temperature difference Thermoelectric Cooling (TEC) modules. The cooling output of the module may reach tens of watts and its temperature difference is more than 90℃. Hui Mao is capable of supplying this kind of cooling module in large quantities. The success of the multi-stage TEC modules brings hope in developing a whole new generation of electric cooling refrigerator, wine cooler and air cooler. Our multi-stage thermoelectric cooling modules also can be used for cooling infrared photodetectors, deep chilling systems, X-ray detectors, etc.

Thermoelectric technology is an active thermal management technique based on the Peltier effect. It was discovered by J.C.A Peltier in 1834, this phenomenon involves the heating or cooling of the junction of two thermoelectric materials(bismuth and telluride) by passing current through the junction. During operation, direct current flows through the TEC module causing heat to be transfered from one side to the other. Creating a cold and hot side. If the direction of the current is reversed, the cold and hot sides are changed. Its cooling power also can be adjusted by changing its operating current. A typical single stage cooler (Figure. 1) consists of two ceramic plates with p and n-type semiconductor material (bismuth ,telluride) between the ceramic plates. The elements of semiconductor material are connected electrically in series and thermally in parallel.
