The invention relates to a case fan control device. The problems that a case multi-fan control system cannot resist static electricity and is unstable in operation are effectively solved. According tothe technical scheme, the case fan control device comprises a case body provided with a plurality of fans, wherein a control device is fixed to the case body, and the control device can enable any one of the fans to rotate reversely; the control device comprises two fixing rings, a cylindrical rod is fixed into the two fixing rings, three annular grooves are evenly distributed in the outer edge face of the cylindrical rod in the circumferential direction, electrode plates are mounted at the bottoms of the annular grooves, the middle electrode plate is a positive electrode, and the two sides of the middle electrode plate are negative electrodes; a plurality of guide rods in the front-back direction are evenly distributed on the front fixing ring and the rear fixing ring in the circumferential direction, the guide rods can move front and back and reset forwards, a housing is mounted in the middle of each guide rod, and two contacts capable of stretching out and drawing back and resetting inwards are arranged in each housing; and after moving front and back along with the guide rods, the contacts can be placed in the different annular grooves, and the positive electrodes and the negative electrodes of the contacts are changed. The case fan control device is safe, reliable and high in stability.
Description
technical field [0001] The invention relates to the field of computer cases, in particular to a case fan control device. Background technique [0002] At present, in most industrial sites, such as textile factories, machining factories, and various manufacturing plants, most of these environments cannot use cooling equipment such as air conditioners, and there are many cotton wools in the textile factories, and the environment is stuffy and dusty. Due to the poor heat dissipation of the computer used in the scene, various problems such as downtime and abnormal heating often occur; In order to prevent the filter on the computer from being clogged, an electronic control chip is separately installed inside each chassis to control the steering of the fan through a combination of software and hardware, so as to effectively realize heat dissipation and dredging through the filter. However, this single electronic chip cannot effectively prevent static electricity. In winter, the c...
