Benefits of technology

"The present invention provides a fan module for a portable device that extracts hot air from the device to the outside. The fan module has a housing with an air inlet and outlet, and a mounting space where the fan is installed. The fins are aligned in parallel and fitted inside the air outlet, creating slots with a width between 0.8 mm and 1 mm. The longitudinal direction of the air outlet is parallel to the direction of alignment of the fins. The fan module prevents small conductive objects from entering the device via the air outlet. The technical effects of the invention are improved cooling of the device and protection against damage caused by small objects."

Problems solved by technology

Because the space within a notebook computer is quite limited, the heat generated by various electronic devices is quickly accumulated in the air inside the computer.
If the small conductive object happens to contact any electrical contacts or circuits inside the notebook computer by accident, a short circuit may occur leading to a mal-function.

Abstract

A fan module comprising a housing, a fan and a plurality of fins is provided. The housing has a mounting space, an air inlet and a corresponding air outlet. The mounting space links the air inlet to the air outlet. The fan is installed within the mounting space. The fins are aligned in parallel and fitted inside the air outlet. The fins divide the air outlet into a plurality of parallel slots, each of which has width less than or equal to 1 mm.

Description

BACKGROUND OF INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a fan module. More particularly, the present invention relates to a fan module installed inside an electronic device for moving hot air from the interior of the electronic device to the exterior. [0003] 2. Description of the Related Art [0004] With great advance in computer technology, the operating speed of computers has been increased constantly so that the total amount of heat generated by electronic devices within the computer host also increases correspondingly. To prevent the internal electronic devices from temporary or permanent damage due to over-heating, an efficient cooling system must be installed inside the computer. Aside from adding a heat-dissipating system to the power supply, the central processing unit (CPU), the graphic processing unit (GPU) and the chipset of a computer to lower the operating temperature of various electronic devices, a fan module is often installed ...
