CN-224232127-U - Temperature control system and sample processing equipment

Abstract

The application provides a temperature control system and sample processing equipment, the temperature control system comprises a sample processing container, a first circulating pipeline, a temperature regulating device and a second circulating pipeline. Through setting up two independent first circulation pipelines and second circulation pipeline, set up temperature regulating device on the second circulation pipeline in order to adjust the liquid temperature in the second circulation pipeline, utilize the mode of heat exchange between first circulation pipeline and the second circulation pipeline to change the liquid temperature in the first circulation pipeline to communicate first circulation pipeline and storage chamber, and then change the temperature in the storage chamber through the mode of heat exchange. The storage cavity is not communicated with the second circulating pipeline, so that liquid in the storage cavity cannot be exchanged with liquid in the second circulating pipeline, even if a sample in the storage cavity leaks, the temperature adjusting device on the second circulating pipeline cannot be influenced, and the problem that a water chiller is inconvenient to clean due to pollution of a circulating waterway caused by leakage of the sample in the existing constant-temperature cavity can be solved.
