Problems solved by technology

In response to different customer needs, different numbers of fans are required in the product. When each product is shipped, if there are different product lines for such customized needs, it will be a great burden on production.
At the same time, when the customer is using the system, if a fan in the system fails, it will cause great trouble to the product user or manufacturer. Due to the complex structure of the electronic system, the failure of a single part must disassemble the system and replace it again. A faulty part, which is extremely difficult for the end user, and for the manufacturer, if the machine must be recycled or sent to the client for repair, it is also a great waste of resources

Abstract

The present invention provides a fan cooling module, the fan cooling module includes a module shell; and a fan is arranged in the module shell. The fan includes an outer frame; a first rotor with a transmission shaft, a hub and a plurality of moving blades arranged around the hub; a base arranged in the outer frame; a second rotor through The transmission shaft is coupled with the first rotor; and a driving device is received by the base for driving the first and second rotors.

Description

technical field [0001] The invention relates to a fan cooling module, in particular to a fan cooling module designed by using a high-efficiency single motor to drive a single or multiple rotor fans. Background technique [0002] With the vigorous development of the electronic industry, while the heat generated by electronic components is gradually increasing, the previous method of using natural convection to solve the waste heat is gradually not enough. At this time, the fan provides an excellent choice. The fan in the current computer system has become a An indispensable element. [0003] In the fan architecture, the motor provides the power needed to turn the rotor. The high heat of general electronic components requires the fan to provide higher air volume, and one of the ways for the fan to provide high air volume is to increase the fan speed. However, in the design of the fan, it is impossible to increase the speed infinitely, because when the fan blade is at a high ...
