The housing 1 is made entirely of stainless steel, welded from 1mm thick stainless steel plates to ensure long-term stability and corrosion resistance. The movable partition 5 is made of 6061-T6 aluminum alloy with an oxidized surface for enhanced wear resistance. The first guide rail 34, the second guide rail 45, and the guide pulleys 52 are made of high-molecular-weight polyethylene, which has a low coefficient of friction and is wear-resistant. The temperature control system is responsible for regulating the temperature of the entire test chamber, achieving rapid heating and cooling as well as constant temperature maintenance through a precise controller. The refrigeration unit in the temperature control system is a fully enclosed compressor with a wide power range to meet various temperature change requirements. The heating element is a PTC ceramic heating element with self-limiting temperature characteristics and good safety. The fan is a centrifugal fan driven by a DC speed-regulating motor, offering flexible airflow adjustment and low noise.

[0034] During use, the required layout of the partitions 5 is first determined according to the actual size of the sample to be tested. Then, the partitions 5 are manually pushed to adjust their positions, dividing the testing chamber into multiple independent testing spaces. The samples are then placed in different testing spaces. The temperature control system then operates alternately according to a pre-programmed sequence to raise and lower the temperature inside the testing space and test the samples. During operation, each sample is located in an independent small space, effectively reducing external combustion and ensuring temperature uniformity, thus improving the accuracy of sample testing. It also facilitates the simultaneous testing of different batches of samples, expanding its applicability.
