Can products withstand in fields such as materials science, electronic manufacturing, and automotive industryAffected by extremeTemperature change is the core indicator for measuring its reliability. copal64LThe thermal shock test chamber, with its excellent technical performance and user-friendly design, has become an industry testing equipmentThe benchmarkIts advantages and maintenance methods are worth exploring in depth.

1、 Technical advantage: Accurately simulating extreme environments to improve testing efficiency

Rapid temperature change, precise controlThe device adopts a binary stacked air-cooled refrigeration system, equipped with a French Taikang fully enclosed compressor and a German Bitzer semi enclosed compressor, to achieve-80℃to220℃Wide temperature range coverage. Its core advantage lies in the temperature conversion time≤8Seconds, recovery time≤5Minutes, far exceeding industry standards. For example, when testing metal fatigue, it is possible to5Complete within minutes-65℃to200℃The cyclic impact accurately captures micro cracks caused by thermal expansion and contraction of materials.

Three box structure, flexible operationThe equipment adopts independent design of high temperature box, low temperature box, and testing box, and achieves rapid exchange of cold and hot airflow through air door switching. The test sample is stationary in the middle testing chamber to avoid vibration interference caused by the movement of the basket in traditional two box equipment, especially suitable for reliability testing of precision electronic components. In addition, the box is equipped with top lead holes and moisture-proof observation windows, which support real-time monitoring and sensor access, enhancing testing flexibility.

Intelligent control, data traceabilityEquipped with JapanOYODual loop high-precision LCD touch controller, supporting10×99Duan program setting, customizable temperature curve, cycle times, and defrosting cycle. The system automatically records running time, fault codes, and temperature curves, and uses485Export data through communication interface to meet the requirementsISO 17025International standards require traceability of experiments.

2、 Maintenance method: Scientific maintenance to extend equipment life

Daily cleaning and sealing inspectionAfter daily testing, wipe the inside and outside of the box with a soft cloth, focusing on cleaning the heat sink and air filter to prevent dust from blocking and affecting the cooling efficiency. Check the door seal for aging and deformation every week, and replace the silicone foam strip in a timely manner to ensure sealing. For example, a certain automotive parts manufacturer failed to replace the sealing strip in a timely manner, resulting in severe frosting in the low-temperature tank and a decrease in refrigeration efficiency30%After replacement, it will return to normal.

Deep maintenance of refrigeration systemCheck the pressure gauge and oil level of the compressor every month, clean the dust on the surface of the condenser, and prevent overheating protection shutdown. Detect refrigerant leaks quarterly, use electronic leak detectors to locate leak points, and supplement in the United StatesR404AEnvironmentally friendly refrigerant. A certain electronic company's failure to conduct regular leak checks resulted in the compressor burning out due to a lack of refrigerant, and the maintenance cost was as high as5Ten thousand yuan.

Calibration and replacement of key componentsEntrust a metrology institution to calibrate temperature and humidity sensors every six months to ensure temperature fluctuations≤±1.0℃Check the heating tube and fan motor annually, clean the dust around the heating tube, and lubricate the fan bearings. A material laboratory learned a profound lesson from a fire caused by bearing jamming due to failure to lubricate the fan motor.
