Benefits of technology
"The present invention provides a waterproof heat-dissipating fan that solves the problem of waterproof protection for circuit boards. The fan has a stator with a coil and a circuit board, which are connected through a conductive member that penetrates a sealed room in the fan frame. The sealed room is designed to accommodate the circuit board and provide waterproof protection for it. The fan can be used in various electronic devices that require waterproof protection."
Problems solved by technology
However, the conventional heat-dissipating fans don't provide a waterproof function.
The circuit board in the fan may have a short circuit when being contact with water to result in malfunction of the fan.
The expensive server or other apparatus may be burned or damaged.
1. The cost is expensive, which is unfavorable to competition;
2. The electronic components on the circuit board may be damaged during the process of plating film, which results in malfunction of the fan;
3. It is difficult to find out the damage of the products in case of collision, which is unable to ensure the quality of the products.
In this way, the glue is thick, which influences the heat dissipation of the circuit board.
The circuit board may be burned easily and the fan malfunctions.
Besides, to coagulate the glue generates internal stress which may damage the electronic components on the circuit board.

Embodiment Construction
[0025]Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
[0026]As shown in FIG. 1 to FIG. 5, a waterproof heat-dissipating fan according to a first embodiment of the present invention comprises a stator 10 and a rotor 20.
[0027]The stator 10 comprises a fan frame 11, a coil 12 and a circuit board 13. The fan frame 11 has an axle 110 extending upward from a bottom of the fan frame 11. The coil 12 is fitted on the axle 110. The axle 110 is provided with a partition board 111. The partition board 111 has a chamber 112 facing downward. The fan frame 11 comprises a waterproof lid 113 to cover the chamber 112 from bottom to top. A sealed room 114 is defined between the waterproof lid 113 and the partition board 111. The waterproof lid 113 has engaging legs 1131 corresponding to engaging recesses 115. A washer 1141 is provided between a circumferential portion of the waterproof lid 113 and the chamber 112. The wash...

A waterproof heat-dissipating fan includes a stator and a rotor. The stator includes a fan frame, a coil and a circuit board. The coil is fitted on an axle of the fan frame. The circuit board is fixed under the coil. The axle is provided with a partition board. The fan frame includes a waterproof lid to cover the partition board and a sealed room defined between the waterproof lid and the partition board. The circuit board is located in the sealed room. The coil is located out of the sealed room. The coil is electronically connected with the circuit board through a conductive member which penetrates the sealed room. The sealed room is provided to accommodate the circuit board and the circuit board is connected with the coil out of the sealed room through the conductive member, providing a waterproof protection for the circuit board.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention The present invention relates to a heat-dissipating fan, and more particularly to a waterproof heat-dissipating fan.[0002]2. Description of the Prior Art[0003]Heat-dissipating fans are widely used along with the development of science and technology, from a CPU to a server; from a simple communication apparatus to an outdoor base station. Nowadays, the heat-dissipating fans are gradually important. However, the conventional heat-dissipating fans don't provide a waterproof function. The circuit board in the fan may have a short circuit when being contact with water to result in malfunction of the fan. The expensive server or other apparatus may be burned or damaged.[0004]Therefore, there are some waterproof heat-dissipating fans on the market, which adopt two ways: one is that the circuit board is treated with a vacuum plating film, and the other is treated with glue-filling.[0005]The vacuum plating film is that the surface o...
