It is not possible to provide stable pressure of carbon dioxide gas for a long time, and the gas pressure cannot be adjusted in accordance with the practice.

Therefore, the purpose of the present invention is to provide a cooling device that can control the pressure value of carbon dioxide gas and increase the supply time.

Therefore, the cooling device of the present invention is used to provide a cooling fluid containing at least compressed gas and carbon dioxide particles formed by the phase change of carbon dioxide gas.

The first barometer 81 is used to detect a first air pressure value H1 of the high-pressure carbon dioxide gas output by the pressurizing pump 52. In this embodiment, the first barometer 81 is installed on a pipeline connected to the pressure pump 52 and used to output high-pressure carbon dioxide gas to the heat exchange unit 6.

The second barometer 82 is used to detect a second air pressure value H2 of the low-pressure carbon dioxide gas input to the pressurizing pump 52. In this embodiment, the second barometer 82 is installed on a pipeline connected to the pressurizing pump 52 and used for inputting low-pressure carbon dioxide gas from the low-pressure steel bottle 2.

The warning element 83 is used to generate a first warning message S1 and a second warning message S2. The warning element 83 may be a display, or a buzzer, or a light-emitting element, the first warning message S1 or the second warning message S2 may match the display as text, or the buzzer as sound, or the light-emitting element as bright light .

The central control module 84 is used to control the opening or closing of the first flow valve 71, the second flow valve 72, and the third flow valve 73, and according to a preset first pre-pressure value H, the When a pressure value H1 and the first pressure value H1 are less than the first pre-pressure value H, the warning element 83 is controlled to generate the first warning message S to warn that the first pressure value H1 of the output high-pressure carbon dioxide gas is abnormal, And according to a preset second pre-pressure value H', when receiving the second air pressure value H2 and the second air pressure value H2 is less than the second pre-pressure value H', control the warning element 83 to generate the second warning The message S2 is used to warn that the second pressure value H2 of the input low-pressure carbon dioxide gas is abnormal.

When the piston end (not shown) in the pressurizing pump 52 reciprocates due to pressure imbalance, it will continue to push the carbon dioxide gas into the gas storage tank 51 and increase the gas storage tank 51 When the first gas pressure value H1 reaches the preset pressure value, it stops.

In this way, in the cutting process, the airflow and carbon dioxide particles are used to smoothly remove the dust on the surface of the workpiece to achieve the effect of cooling and cleaning.

In the process of spraying the cooling fluid, the central control module 84 controls the warning element 83 to generate the first warning message S when the first air pressure value H1 is less than the first pre-pressure value H to warn the output If the first pressure value H1 of the high-pressure carbon dioxide gas is abnormal, the gas pressure may not meet the demand, and the central control module 84 will also control the second pressure value H2 when the second pressure value is less than the second pre-pressure value H' The warning element 83 generates the second warning message S2 to warn that the input second low-pressure carbon dioxide gas has an abnormal second gas pressure value H2, indicating that the carbon dioxide gas in the low-pressure steel cylinder 2 may be exhausted soon, and the low-pressure steel cylinder 2 may be prepared to be replaced.
