In some embodiments, the temperature control device 104 includes a temperature sensor 105, where the temperature sensor 105 is disposed in a preset tank, and is configured to obtain a temperature in the preset tank to output a temperature signal. The temperature control cooling device detects the temperature in the preset box through the temperature sensor 105, and the temperature control device 104 can control the valve 103 according to the temperature signal output by the temperature sensor 105, namely, can control the valve 103 according to the temperature in the preset box so as to control compressed gas to enter the vortex tube 100, so that the vortex tube 100 generates cold air flow and outputs the cold air flow. The temperature control cooling device can control whether cold air flow is input into the preset box according to the temperature in the preset box, and an intelligent temperature control cooling scheme is realized.
