Refrigeration system 4 is controlled to reduce temperature；If temperature is less than design temperature, control heating system 5 heats to heat to realize
Cooling gas is heated to user by pipe 511 needs the temperature that exports.
To sum up, the impact system in above-mentioned thermal shock machine employs the conversion of quick temperature, maximum temperature difference scope
At -80 DEG C~225 DEG C, and from -55 DEG C of cold shock patten transformation to 100 DEG C of thermal shock pattern and 100 DEG C of heat punching
The cold punching blow mode that blow mode is transformed into -55 DEG C only needs 10 ~ 20 seconds or so cans to change successfully, and uses power energy consumption
Few, energy consumption is in 4.5KW or so after tested, and the temperature difference, at ± 1 DEG C, temperature control precision is high.Cool without preheating without pre-,
And aided in without liquid nitrogen, improve efficiency, save energy consumption.
This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model
Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but
As long as all protected in right of the present utility model by Patent Law.
