Description
Technical Field
The invention relates to a fan with a programmable air outlet, in particular to a fan which can realize rapid change of the direction and the quantity of the air outlet through relative rotation among a plurality of layers of concentric wind shielding cylinders.
Background
Water-cooled heat sinks for computer processor heat dissipation provide a greater heat dissipation effect than air-cooled heat sinks through the circulating flow of a liquid medium and high heat capacity. However, the water-cooled radiator has a problem that the water-cooled radiator replaces an air-cooled radiator, and the VRM power supply module and the M.2 equipment around the processor cannot form an air duct and sufficiently drive the air in the case to flow, so that sufficient heat radiation cannot be achieved. In order to solve the problem, the A series mixed water cooling system of Taiwan CryORIG fast technology fixes a fan with the diameter of 70mm, the rotating speed of 1500-3000RPM and the air volume of 25CFM and the plane of a main board at an included angle of 45 degrees above a water cooling head, and blows air to a power supply circuit on one side of a processor; the water cooling head of the RYUJIN series integrated water cooling radiator of Taiwan Huashuo computer comprises a centrifugal fan which is parallel to the plane of the main board, has the diameter of 60mm, the rotating speed of 4800RPM and the air volume of 19.41 CFM. The fast and Rui technical scheme adopts an axial fan to mainly blow and radiate a VRM power supply module at one side of a processor, and takes surrounding devices into consideration; the scheme of the Huashuo computer can simultaneously blow and dissipate heat of the VRM power supply module and the M.2 equipment on three sides of the processor. But due to the size limitation of the fan, the fan blows air in the range of 270 degrees on three sides at the same time, so that the heat dissipation effect is insufficient, and the high-speed fan brings high noise.
When the computer carries out overclocking or calculation intensive tasks, the temperature of the VRM power supply module is high, and air flow needs to be concentrated for blowing and heat dissipation; when computers transmit large amounts of data or perform I/O-intensive tasks, the temperature of m.2 devices is high, and if heat dissipation is not timely, the transmission rate is reduced due to the reduction of frequency. If the direction and the quantity of the air outlets of the fan can be adjusted according to different states of each part when the computer executes different tasks, the requirements on the performance and the rotating speed of the fan can be greatly reduced, and the noise is reduced.
The invention therefore proposes a fan with a programmable outlet, in particular a fan in which the direction and number of outlets are rapidly changed by relative rotation between a plurality of concentric wind-deflecting cylinders.
