Problems solved by technology

During operation, one or another of the cooling fans may fail, due to, e.g., aging.
Therefore, the air at the air outlet of the failed cooling fan has a tendency to flow to the air inlet of such cooling fan due to the air pressure difference.
This results in a reduction of the total airflow provided by the other cooling fans to the electronic components.
Accordingly, the heat dissipation of the electronic components is further impaired.

Embodiment Construction

[0013]FIG. 1 shows a fan apparatus 100 according to an embodiment of the disclosure. In typical use, a plurality of the fan apparatuses 100 can be installed in an electronic device, such as a server or a computer, side by side in parallel to dissipate heat from electronic components of the electronic device.

[0014]The fan apparatus 100 includes a cooling fan 10, a fan gate 20, and a fixing frame 30 for fixing the fan gate 20 onto the cooling fan 10.

[0015]The cooling fan 10 includes a fan housing 11, and a rotor 12 for generating a forced airflow. The fan housing 11 is square-shaped and hollow, and the rotor 12 is received in the fan housing 11. A rear side of the fan housing 11 defines an air inlet 14 of the cooling fan 10 for the forced airflow to enter the fan housing 11, and a front side of the fan housing 11 defines an air outlet 15 of the cooling fan 10 for the forced airflow to exit the fan housing 11.

[0016]A base 16 is received in the fan housing 11 and arranged at the air out...

Abstract

An exemplary fan apparatus includes a cooling fan and a fan gate attached to the cooling fan. The cooling fan defines an air inlet and an air outlet at two opposite sides thereof. The fan gate includes a mounting frame fixed on the cooling fan and surrounding the air outlet, and an airflow valve extending from the mounting frame. The airflow valve is bendable relative to the mounting frame. When the cooling fan works, an airflow produced by the cooling fan flows to the fan gate and pushes the airflow valve to bend with respect to the cooling fan to cause the air outlet to be exposed. When the cooling fan does not work, the airflow valve covers the air outlet.

Description

BACKGROUND[0001]1. Technical Field[0002]The disclosure generally relates to cooling devices for electronic apparatuses, and particularly to a fan apparatus incorporating a fan gate.[0003]2. Description of Related Art[0004]Cooling fans are often applied in electronic devices, such as a computers or servers, to dissipate heat from electronic components of the electronic devices. Typically, the cooling fans are arranged side by side, in parallel. Air outlets of the cooling fans are located at a same side of the bank of cooling fans, thus increasing an area that airflow of the cooling fans flows to. Accordingly, the cooling fans are capable of cooling many more electronic components simultaneously.[0005]During operation, one or another of the cooling fans may fail, due to, e.g., aging. At that time, the other cooling fans continue working and drive air from their air inlets to their air outlets. Accordingly, air pressure at the air outlets of the bank of cooling fans exceeds that at the...
