Semiconductor thermoelectric cooler, also known as semiconductor chiller, semiconductor temperature control console, precision semiconductor cooler, is composed of semiconductor refrigeration system, circulating water cooling system, temperature control system, and measuring fixture platform. Widely used in semiconductor industry etching devices, CMP laboratory precision devices, high-precision testing instruments, etc

In terms of reliability testing for automotive grade chips, Shanghai Putaike High and Low Temperature Testing Machine has unique advantages that are different from traditional high and low temperature impact testing chambers: fast temperature change rate, fast temperature rise/fall of 18 ℃ per second, real-time monitoring of the actual temperature of the tested component, and the temperature of the impact airflow can be adjusted at any time. It can perform high and low temperature impact on a single IC among many components on the PCB circuit board separately, without affecting other peripheral components

The Putek PTLD series low-temperature refrigeration unit includes a compressor, pump, expansion chamber, evaporator, and condenser module, which can use single compressor and self cascade refrigeration technology, with strong refrigeration capacity; Environmentally friendly mixed refrigerant, energy-saving and environmentally friendly; Large caliber glass level gauge, easy to observe; Adopting a fully enclosed structural design to avoid low-temperature water absorption by the cooling medium; Importing refrigeration accessories to ensure reliable operation of equipment is an environmentally friendly and economical refrigeration solution.

It mainly consists of heating circulation system, cooling system, control system, box, etc. The heating cycle system consists of a circulation pump, an electric heater, an expansion vessel, an exhaust valve, a one-way valve, a thermal resistor, and a circulation pipeline. The cooling system consists of oil-water heat exchangers, oil-oil heat exchangers (some equipment), cooling water solenoid valves, high-temperature solenoid valves, etc. The control system adopts PID control technology, high-definition touch screen display, and is equipped with multiple protection functions to ensure the safe operation of the equipment. By heating and cooling the unit itself, the heat carrying fluid is transported to the outside world to meet the requirements of the process conditions.
