Description

A turbo type high speed fan device

technical field

The utility model relates to a turbo type high speed fan device.

Background technique

A fan refers to an electric fan used to generate wind to keep cool in hot weather. It is a device driven by electricity to generate air flow.

Ordinary fan is a kind of axial flow fan. The air flow in the motor part cannot pass through, so there will be a "blind area" if there is no air flow in the center, and the air flow is more turbulent. The cooling in the center is not good.

The other name of centrifugal fan is common in the field of personal computer heat dissipation, and it is customary to refer to small centrifugal fans as turbofans. The gas flow direction of the turbofan is perpendicular to the rotation axis, while the gas flow direction of the common axial fan is parallel to the rotation axis.

Compared with the traditional cooling fan, the centrifugal fan can output a larger air volume and improve the cooling effect while occupying a smaller space. However, the machining accuracy of centrifugal fan blades is higher than that of ordinary fans, and the noise generated when the impeller has dust accumulation or high-speed operation is also greater. Now with the decrease of CPU power consumption, CPU turbo fans are gradually replaced by large-diameter low-speed ordinary axial-flow silent fans, but they are still often used on high-performance graphics cards, especially public graphics card radiators.

The centrifugal fan is driven by the motor to rotate the impeller. The blades in the impeller force the gas to rotate and do work on the gas to increase its momentum. Under the action of centrifugal force, the gas is thrown around the impeller, and the kinetic energy is converted into pressure through the volute casing. Yes, when the gas in the impeller is discharged, the pressure in the impeller is lower than the pressure in the air inlet pipe, and the new gas is sucked into the impeller under the action of the pressure difference, and the gas is continuously discharged from the fan.

Contents of the invention

The technical problem to be solved by the utility model is to provide a turbine type high-speed fan device.

The technical scheme adopted in the utility model is:

A turbo-type high-speed fan device, its structure includes a turbo fan, a fan impeller, a power supply interface, an air inlet, an air outlet, and a turbocharger chamber, the turbofan is located in the middle of the fan, and the fan impeller is arranged in the turbocharger chamber , the turbocharging chamber is annular, and the cross-sectional area of the ring connected to the air outlet is greater than the cross-sectional area of the end away from the air outlet. The design of the turbocharger chamber, which is small at the top and large at the bottom, can increase the wind speed and make the sent wind more powerful.

The air outlet is arranged at the outer circumference of the turbocharging chamber along the tangent line, the cross section is rectangular, and a slot-shaped air outlet is arranged in the air outlet, and the slot-shaped air outlet is a cylindrical structure composed of several air guide vanes vertically , the direction in which the plane of each air guide vane is set corresponds to the direction in which the air guide port is set. This can make the air volume of the air outlet uniform and the air supply stable.

A plurality of air inlet guide vanes are arranged at the position of the air inlet of the fan. In this way, the air intake of the air inlet can be kept uniform, and vibration and noise caused by uneven air intake can be avoided.

The beneficial effects of the utility model are as follows: the utility model has reasonable structural design, low noise, strong wind, and rapid heat dissipation. At the same time, the turbo blower is located in the middle, and the outer surface has no blades, which is safe and reliable, and the outer surface is smooth and easy to clean.
