Cooling device for numerical control fan

Abstract

The invention discloses a cooling device for a numerical control fan, and belongs to the technical field of fan cooling. The cooling device comprises a casing. An impeller is arranged inside the casing. An air inlet is formed in the surface, corresponding to the position of the impeller, of the casing. The surface, corresponding to the air inlet, of the casing is detachably connected with a purification device. Through the effective coordination of the designed purification device, spiral tubes, refrigeration fins, coolant and a noise reduction shield, impurities can be prevented from adheringto a bearing box, so as to not only prevent the impurities from increasing the friction between a spindle and a bearing in the bearing box, but also ensure the cooling effect of air flowing in an airchannel on cooling water or lubricating oil flowing in the cooling channel. A motor can be cooled. To a certain extent, the cooling device can reduce the heat generated by the motor during operationand is transmitted to the bearing in the bearing box through the spindle, so that the bearing in the bearing box can be further protected and the stability of the bearing in the bearing box can be ensured.

Description

technical field [0001] The invention belongs to the technical field of fan cooling, and in particular relates to a cooling device for a numerically controlled fan. Background technique [0002] The fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. Fan is the customary abbreviation for gas compression and gas conveying machinery in China. Generally speaking, fans include ventilators, blowers, and wind generators. [0003] The main structural components of the fan are the impeller, casing, air inlet, bracket, motor, pulley, coupling, muffler, transmission parts (bearings), etc. [0004] The CNC fan is a modern intelligent fan. In order to ensure that the CNC fan can work for a long time, it is necessary to use a corresponding cooling device to cool the CNC fan. For example, "a cooling device for numerically controlled fan" (Patent No.: CN 209053835 U) disclosed in China Patent Network...

Problems solved by technology

For example, "a cooling device for numerically controlled fan" (Patent No.: CN 209053835 U) disclosed in China Patent Network, the technical problem solved by this patent is that the existing heat dissipation method usually adopts the bearing box, and the bearing box is installed with the The water inlet and the water outlet are connected internally, and the cooling water circulates inside the bearing box to take away the heat and complete the cooling of the main shaft and the bearing. However, this method requires the introduction of a separate water pump from the outside, and the cost is high. The patent adopts the design of the ring This technical problem has been solved under the interaction be
