Problems solved by technology
However, all necessary electronic components need to be arranged in the limited area of the circuit boards 141a and 141b to meet the requirements of heat dissipation, which often causes problems in fan design.
In addition, as a result of the high density of electronic components, once the local areas on the circuit boards 141a, 141b have poor heat dissipation, the circuit boards 141a, 141b are often easily damaged, and it takes a lot of time to disassemble or replace the entire double rotor blade. The fan 1 leads to a waste of user time and a shortened service life, resulting in economic waste

Embodiment Construction
[0043] see figure 2 , figure 2 It is a schematic diagram of a double moving blade fan according to a preferred embodiment of the present invention. The double moving blade fan 2 includes two moving blades 22 a , 22 b , two motors 24 a , 24 b and a circuit board fixing frame 26 . The moving blades 22a, 22b are respectively driven by motors 24a, 24b. The motor 24a has a circuit board 241a, a stator 242a and a rotor 243a, and the rotor 243a is coupled to the stator 242a. The motor 24b has a circuit board 241b, a stator 242b. With a rotor 243b, the rotor 243b is coupled to the stator 242b, the circuit boards 24a, 24b are arranged facing away from each other, and the circuit board fixing frame 26 is arranged between the two motors 24a, 24b.

The invention provides a double moving blades fan which includes a first moving blade, a second moving blade, a first motor, a second motor and a circuit board fixing frame. The first motor and second motor drive the first moving blade and second moving blade respectively, the circuit board fixing frame includes a plate and a plurality of supporting pieces that are set between the first motor andsecond motor. The plate includes a first surface and an opposite second surface, the supporting pieces are set on two sides of the plate respectively, and protrude on the first surface and second surface respectively. When the first motor assembly with the second motor, the supporting piece protruded on first surface props up a first circuit board, and the supporting piece protruded on second surface props up a second circuit board.
Description
technical field [0001] The invention relates to a circuit board fixing frame, its dual motor device and a double-moving-blade fan, in particular to a double-moving-blade fan matched with a circuit board fixing frame. Background technique [0002] With the rapid advancement of technology, electronic products are also developing towards thinner, lighter and smaller designs. However, such electronic products often generate a large amount of waste heat due to the high density of electronic components. If they cannot be dissipated in a timely manner, it may cause a short circuit or damage the product or data. Therefore, the use of heat sinks has become an indispensable role in the development of the electronics industry. [0003] Among many heat dissipation devices, the fan is a heat dissipation device with great application value. However, sometimes a single fan is not enough to dissipate the heat of electronic products due to the limited air volume, so multiple fans are used ...
