A mixed flow fan

Abstract

The invention discloses a mixed-flow fan, comprising a casing, a motor arranged in the casing, and a first fan arranged on an output shaft of the motor. A first connecting block is arranged in the casing, and the first A fixing ring is arranged on the connecting block, the motor is arranged in the fixing ring, a first fixing plate is arranged on the top of the fixing ring, and a plurality of first fixing springs are arranged on the side wall of the first fixing plate, so A second fixing plate is arranged at the bottom of the fixing ring, and a plurality of second fixing springs are arranged on the side wall of the second fixing plate; Two liquid storage chambers, the first liquid storage chamber is filled with cooling liquid, and when the fan works, the cooling liquid in the first liquid storage chamber enters the second liquid storage chamber.

Description

technical field [0001] The invention belongs to the technical field of fans, in particular to a mixed flow fan. Background technique [0002] Many production and living occasions need to strengthen heat dissipation to avoid heat accumulation. For example, many electrical and electronic components need to be dissipated during use to avoid component damage due to heat accumulation. [0003] At present, the main means of heat dissipation is to use fans to dissipate heat. Fans can provide cooling air with a certain air pressure and air volume to achieve heat dissipation, and are the main means of heat dissipation in many occasions, especially for electrical and electronic components. The air pressure and air volume of the cooling air are positively correlated to the cooling effect. Therefore, in order to obtain a good cooling effect, the cooling air pressure and air volume provided by the fan need to be able to meet the requirements. [0004] In the prior art, cooling fans ca...

Problems solved by technology

[0005] The occasion where the cooling fan works is usually a high-temperature environment. When the fan is working, the motor itself will generate heat. The long-term operation of the motor in a high-temperature environment requires high performance of the motor, and the service life of the motor is reduced. In the prior art, the cooling liquid is used. The motor of the fan is used for cooling, but the coolant heats up slowly and also cools down slowly. When the fan is not working, the coolant slows down the cooling speed of the motor and increases the time the motor is in a high-temperature environment, which reduces the cooling effect on the motor.
