Description

Elastic wind choke

The present invention relates to an elastic choke sheet, in particular to an elastic choke sheet used for blocking air flow through a gap inside an electronic device.

Please refer to the first figure and the second figure, the first figure is a three-dimensional schematic view of the electronic device of the prior art, and the second figure is a plan view of the electronic device of the prior art without a windshield. As shown in the first and second figures, the conventional electronic device PA100 includes a casing PA1, a circuit board assembly PA2, and a windshield PA3; wherein the circuit board assembly PA2 includes a plurality of electronic components PA21 (in the figure, only One is marked), and the windshield PA3 is arranged above the circuit board assembly PA2 and fixed to the chassis PA1 to restrict the flow direction of the airflow, so that the cooling airflow can pass between the circuit board assembly PA2 and the windshield PA3. , and then dissipate heat to the electronic component PA21 on the circuit board assembly PA2.

Based on the above, although the design of the windshield PA3 can make the heat dissipation airflow concentrated between the windshield PA3 and the circuit board assembly PA2, there is often a gap between the electronic component PA21 and the chassis PA1, so the heat dissipation The airflow is likely to be diverted to the gap, which relatively reduces the flow between the plurality of electronic components PA21, resulting in a reduction in the heat dissipation effect of the circuit board assembly PA2.

Please continue to refer to the third figure. The third figure is a schematic plan view of an electronic device of the prior art provided with a wind blocking element. As shown in the second and third figures, in order to improve the problem that the flow rate between the plurality of electronic components PA21 is relatively reduced due to the shunting of the cooling airflow to the gap, a wind choke element PA200 is usually provided inside the casing PA1 in the prior art. The above-mentioned gap is filled by the wind blocking element PA200, which effectively blocks the flow of airflow.

The wind blocking element used in the prior art is usually a foam block or a hard caulking gasket. However, although the foam block is elastic as a wind blocking element, its structure is relatively loose, and it is easy to deteriorate due to aging or assembly of the circuit board assembly PA2. During the time of hooking, the dust or foam shavings after the deterioration of the foam block enters the circuit board assembly PA2, which leads to problems such as poor signal or short circuit. However, in order to install the caulking gasket on the chassis PA1, it is necessary to process the opening of the chassis PA1, and the assembly process of the circuit board assembly PA2 is also prone to wear and tear due to friction.
