Description

Wind direction outlet control device

technical field

The invention relates to a wind direction outlet control device, which includes a fan and a frame body. The fan is arranged in the frame body, on a wheel hub seat, and is provided with radially arranged fluid control components connected to the frame body and the wheel hub seat.

Background technique

Today's electronic products are miniaturized and high-frequency, and the accompanying high calorific value affects the stability of electronic products. Therefore, it has become an important research topic to effectively and quickly remove waste heat in order to reduce the system temperature. Using a fan is the most economical way to discharge heat. The fan blades are driven by a motor to convert electrical energy into mechanical energy. The energy is transmitted through the blades to cause fluid flow, which increases the convection coefficient in the space, and then utilizes pressure changes and speeds. The flow generated by the increase takes away excess heat to achieve the purpose of heat dissipation.

However, when a general fan is driven by a motor to rotate, the fluid is driven by the fan blades and passes through the fan outlet and then tends to spread out around the fan. This kind of fan that cannot control the flow direction of the fluid will affect the fan hub, causing the fluid to form behind the hub. The large stagnation area makes it difficult to show the heat dissipation effect. If it is installed in an area with poor circulation and high impedance to dissipate heat for electronic components, due to the influence of the stagnation area generated behind the fan hub, the maximum heat dissipation effect can be achieved. The heat dissipation effect of the fluid is really limited, which not only causes the electronic components to easily generate high temperature and even more easily damaged during operation.

As disclosed in Taiwan Patent Gazette, the application number 090118816 is a combined fan and its used fan frame structure, the combined fan and its used fan frame structure, the combined fan includes a fan and a fan frame structure , wherein the fan frame structure includes a first frame and a first guide part, arranged in the first frame, wherein the first guide part is composed of a plurality of stator blades arranged radially, when the fan is running , the air volume and air pressure of the airflow generated by the fan can be increased by means of a plurality of stationary blades.

In the above-mentioned embodiment, although the flow volume is increased, the flow direction of the fluid flowing out by the rotation of the fan is still uncontrollable, so that a relatively large stagnation area is formed behind the fan hub, which cannot effectively dissipate heat.
