Description

Cooling device module

The invention relates to a cooling device module, in particular to a progressively pressurized cooling device module.

As industrial development continues to advance, cooling devices are used in everyday life. The cooling device is a variety of chillers with a cooling function, whereas conventional cooling devices typically use a centrifugal sprinkler to spray against the heat sink. However, when using a centrifugal sprinkler for watering, the sprinkling trajectory must be in an arc, but if the shape of the casing of the cooling device is square, the four corners of the fin in the square casing cannot be centrifugally shaped. Sprinkle the sprinkler into the water. Furthermore, the centrifugal sprinkler is parallel to the heat sink. Once the centrifugal sprinkler rotates too fast, the water will leave in the centrifugal direction, so that some of the water mist is not sprayed onto the heat sink. As the above engineering technology is still unable to break through, the heat dissipation performance is still limited.

Therefore, the industry hopes that the heat sink in the cooling device can be uniformly sprayed by the water mist and can effectively spray the water mist to improve the heat dissipation efficiency of the cooling device, thereby avoiding the energy efficiency value of the conventional cooling device (Energy) Efficiency Ratio; EER) The problem of poor value.
