When the second temperature measuring member 341 detects that the temperature of the working fluid in the second tank 31 is higher than the second temperature, the second control module opens the second switching valve 322 to make the working fluid The second case 31 flows into the first case 21 to cool down, and when the second temperature measuring member 341 detects that the temperature in the second case 31 falls to the second temperature, the second control module The second switching valve 322 is closed.

In addition, when the second temperature measuring member 341 detects that the temperature in the second housing 31 is lower than the second temperature, the second control module activates the second heating unit 35 to heat the working fluid, and waits until When the temperature of the working fluid returns to the second temperature, the second heating unit 35 is turned off, thereby maintaining the temperature of the working fluid constant. The structure of the second heating unit 35, the structure of the second control module, and the circuit design of the second control module controlling the second switching valve 322 and the second heating unit 35 are not the focus of improvement of the present invention. , no longer stated.

However, in practice, the first tank 21 and the second tank 31 may also be a fuel tank or a gas tank, and oil or gas is used as a working fluid, so that it is implemented according to requirements, and is not limited thereto.

In use, the first cooling mechanism 2 transmits the working fluid having a lower temperature in the first tank 21 through the first output section 233 of the first outer tube 231 to the machine through the first outer pump 232. In the first mechanical member 91 of the device 9, the temperature of the first mechanical member 91 is lowered by heat exchange between the working fluid and the first mechanical member 91, so that the first mechanical member 91 can be maintained at the first temperature. Perform processing operations. Next, the first input section 234 of the first outer tube 231 transports the temperature-increased working fluid back into the first tank 21.

At the same time, the first inner pump 222 will also continuously place the first box The working fluid in the body 21 is transferred to the evaporator 12 of the refrigerant mechanism 1 via the first inner tube 221, and the working fluid is cooled by the heat exchange of the evaporator 12, and then the temperature is compared via the first inner tube 221. The low working fluid is returned to the first tank 21, whereby the temperature of the working fluid in the first tank 21 can be maintained at the first temperature to match the cooling demand of the first mechanical member 91.

On the other hand, the second cooling mechanism 3 transmits the working fluid having a lower temperature in the second tank 31 through the second output section 333 of the second outer tube 331 through the second outer pump 332. In the second mechanical member 92 of the mechanical device 9, the temperature of the second mechanical member 92 is lowered by heat exchange between the working fluid and the second mechanical member 92, so that the second mechanical member 92 can be maintained at the second temperature.

Then, the second input section 334 of the second outer tube 331 further transports the temperature-increased working fluid back into the second tank 31, thereby gradually increasing the temperature of the working fluid in the second tank 31.

At the same time, the second temperature measuring member 341 of the second temperature sensing unit 34 continuously detects the temperature of the working fluid in the second housing 31, and when the second temperature measuring member 341 detects the working fluid When the temperature is higher than the second temperature, the second control module of the second temperature sensing control unit 34 turns on the second switching valve 322, and causes the second output tube 321 to compare the temperature in the second housing 31.

It is conveyed back into the second casing 31, thereby lowering the temperature of the second casing 31.

When the second temperature measuring member 341 detects that the temperature in the second housing 31 drops to the second temperature, the second control module closes the second switching valve 322, and the second output tube The 321 is closed to allow the working fluid in the second tank 31 to pass into the first tank 21, thereby preventing the temperature of the working fluid from continuously decreasing below the second temperature. Further, if the temperature of the working fluid in the second tank 31 is lower than the second temperature, the working fluid can be heated by the second heating unit 35.

It is further explained that the temperature provided by the second cooling mechanism 3 can also be the same as the temperature that the first cooling mechanism 2 can provide, that is, the second temperature can also be the same as the first temperature. Since the cooling temperature that the first cooling mechanism 2 and the second cooling mechanism 3 can provide can be adjusted according to the cooling requirement of the mechanical device 9, it is not limited by the form disclosed in the embodiment.

In summary, compared to the general cooling system, only one working fluid can be outputted, which results in the user having to set up multiple cooling systems to meet the cooling requirements of different mechanical components, thus causing the device to become bulky and increase the equipment. Cost and other issues. Since the first cooling mechanism 2 of the present embodiment can output the working fluid maintained at the first temperature to cool the first mechanical member 91, and the second cooling mechanism 3 can output the working fluid maintained at the second temperature to cool the first Two mechanical members 92. Therefore, through the innovative structural design of the first cooling mechanism 2 and the second cooling mechanism 3, the working fluid of different temperatures can be provided to cooperate with the mechanical device 9, Not only the applicability of the embodiment is increased, but also the equipment cost is reduced and the space occupied by the volume of the overall device is reduced.

Referring to Figure 2, a second preferred embodiment of the cooling system of the present invention is substantially identical to the first preferred embodiment, the difference being that the mechanical device 9 further comprises a device adapted to operate at a third temperature. The third mechanical member 93, and the third temperature is higher than the first temperature, and the cooling system further includes a third cooling mechanism 4 for adjusting the temperature of the third mechanical member 93.

The third outer tube 431 has a third output section 433 mounted in combination with the third outer pump 432 and conveying working fluid from the third housing 41 toward the third mechanical member 93, and a working fluid The third mechanical member 93 is directed toward the third input section 434 of the third housing 41.

The third temperature sensing control unit 44 includes a third temperature measuring member 441 mounted in combination with the third housing 41 and capable of detecting the temperature of the working fluid in the third housing 41, and an electrical connection to the third The third control module is not shown, but the third control module can control the operation of the third switching valve 422 and the third heating unit 45.

In use, the first cooling mechanism 2 and the second cooling mechanism 3 respectively perform a cooling and cooling operation on the first mechanical member 91 and the second mechanical member 92, and the third cooling mechanism 4 transmits the third outer tubular unit. After the working fluid having a lower temperature in the third tank 41 is introduced into the third mechanical member 93, the working fluid having an increased temperature is transported back into the third tank 41, thereby cooling the third mechanical member. 93 to enable it to maintain processing at a third temperature.

At this time, the third temperature measuring member 441 of the third temperature sensing unit 44 continuously detects the temperature of the working fluid in the third housing 41, and when the third temperature measuring member 441 detects the working fluid When the temperature is higher than the third temperature, the third control module opens the third switching valve 422, so that the third output tube 421 can pass the working fluid with a higher temperature in the third housing 41 into the third a box The temperature is lowered, and the third input pipe 423 can transport the working fluid having a lower temperature in the first casing 21 from the second input pipe 323 to the third casing 41, thereby lowering the third tank. The temperature of the working fluid within body 41.

When the third temperature measuring member 441 detects that the temperature of the working fluid in the third tank 41 drops to the third temperature, the third control module closes the third switching valve 422 to stop the working fluid from entering.
