AI Technical Summary
Existing thermal shock testing machines require multiple chamber switching during heating and freezing processes, leading to heat convection, making it difficult to reach the required temperature and increasing energy consumption.
An energy-saving thermal shock testing device was designed. An air curtain mechanism is used to set up an air curtain between the cooling chamber and the heating chamber to reduce heat convection. The cooling chamber is located on the lower side, following the principle that cold air flows downward and hot air flows upward, which reduces heat exchange.
It effectively reduces the energy consumption for temperature regulation caused by heat convection, improves the accuracy of temperature control, and reduces energy consumption.
