Systems and methods for an electronic device
View Patent ↗Methods and systems for an electronic package for a vehicle are provided. In one example, the electronic package includes a chassis having a plurality of bent tabs forming a plurality of respective vent openings in the chassis, and a circuit board coupled to the chassis, wherein the bent tabs directly contact the circuit board.
1. An electronic package for a vehicle comprising:
a chassis having a plurality of bent tabs forming a plurality of respective vent openings in the chassis; and
a circuit board coupled to the chassis,
wherein the bent tabs directly contact the circuit board, and
wherein the bent tabs only bend inward in a direction of an interior of the chassis.
2. The electronic package of claim 1 , wherein the bent tabs comprise a bend and a fin having a first face, a second face, and a small side surface.
3. The electronic package of claim 2 , wherein the small side surface of the fin directly contacts an external surface of the circuit board.
4. The electronic package of claim 2 , wherein one of the first or second face of the fin directly contacts an external surface of the circuit board.
5. The electronic package of claim 2 , wherein the first face and the second face of the fin are oriented perpendicular to a surface of the circuit board.
6. The electronic package of claim 2 , wherein the first face and the second face of the fin are oriented parallel to a surface of the circuit board.
7. The electronic package of claim 2 , wherein the bend is located opposite the fin of the bent tabs.
8. The electronic package of claim 1 , wherein a face of the bent tabs makes face-sharing contact with an external surface of the circuit board.
9. The electronic package of claim 1 , wherein the circuit board is joined to the chassis via fasteners inserted through a plurality of aligned through holes.
10. The electronic package of claim 1 , wherein the bent tabs are arranged in a top row and a bottom row, and the top row of bent tabs bend in an opposite direction than the bottom row of bent tabs.
11. The electronic package of claim 1 , the chassis further comprising a back panel having a depression, wherein an internal surface of the depression makes face-sharing contact with an external surface of the circuit board.
12. The electronic package of claim 2 , the chassis further comprising a first pair of opposing parallel walls and a second pair of opposing parallel walls.
13. The electronic package of claim 12 , wherein the bent tabs are located on the first pair of opposing parallel walls, wherein the fin of each of the bent tabs are located on interior side of the first pair of opposing parallel walls.
14. The electronic package of claim 12 , further comprising a fan, and wherein the bent tabs are located on a first wall of the second pair of opposing parallel walls and the fan is located in a second wall of the second pair of opposing parallel walls.
15. A method for cooling an electronic package, comprising:
operating a fan where the fan blows air from inside an enclosure to outside the enclosure, the enclosure comprised of a chassis having the fan, a plurality of bent tabs forming a plurality of respective vent openings in the chassis, and a circuit board coupled to the chassis, wherein the bent tabs only bend inward in a direction of an interior of the chassis, and directly contact the circuit board.
16. A system for a vehicle, comprising:
a vehicle component;
a chassis having a plurality of bent tabs forming a plurality of respective vent openings in the chassis mounted to the vehicle component; and
a circuit board coupled to the chassis,
wherein the bent tabs only bend inward in a direction of an interior of the chassis, and directly contact the circuit board.
17. The system of claim 16 , wherein the vehicle component is an instrument panel.
18. The system of claim 16 , the chassis further comprising a housing, a cover plate fastened over the circuit board to the housing, and a pair of brackets coupled to at least one of the housing and the cover plate, wherein the chassis is coupled to the vehicle component by fasteners inserted through the pair of brackets.
19. The system of claim 16 , wherein the chassis is made from sheet metal.
