Abstract
A dustproof device is disclosed. The first blade set includes a plurality of first blades. The first blade has a first linking portion and a first blocking portion. The first blocking portion forms a first opening with another first linking portion of an adjacent first blade. The second blade set includes a plurality of second blades. The second blade has a second linking portion and a second blocking portion. The second blocking portion forms a second opening with another second linking portion of an adjacent second blade. Dust or particles entering the first blade set will be blocked by the second blade set and fallen between the first blade set and the second blade set.
Claims19
A dustproof device for a heat sink, the heat sink having an air inlet, the dustproof device comprising:
- a first blade set disposed in a lateral side of the air inlet, the first blade set including a plurality of first blades arranged in parallel and at intervals, each first blade having a first linking portion and a first blocking portion extended from the first linking portion, the first blocking portion being a free end and bent in a direction toward the heat sink and forming a first opening with another first linking portion of an adjacent first blade;
- and
- a second blade set disposed between the first blade set and the air inlet, the second blade set including a plurality of second blades arranged in parallel and at intervals, each second blade having a second linking portion and a second blocking portion extended from the second linking portion, the second blocking portion being a free end and bent in a direction away from the heat sink and forming a second opening with another second linking portion of an adjacent second blade,
- wherein an extension line of the first blocking portion is located on the second blocking portion.
A dustproof device for a heat sink, comprising:
- a first blade set provided in a lateral side of the heat sink, including a plurality of first blades arranged in parallel and at intervals, each first blade having a first linking portion and a first blocking portion, the first blocking portion being a free end and connecting with the first linking portion, the first blocking portion of the first blade forming a first opening with another first linking portion of an adjacent first blade;
- and
- a second blade set disposed between the first blade set and the heat sink, the second blade set including a plurality of second blades arranged in parallel and at intervals, each second blade having a second linking portion and a second blocking portion, the second blocking portion being a free end and connecting with the second linking portion, and the second blocking portion of the second blade forming a second opening with another second linking portion of an adjacent second blade;
- wherein, an extension line of the first blocking portion is located on the second blocking portion, and dust or particles entering the first blade set is blocked by the second blade set and fallen between the first blade set and the second blade set.
