Computer provided with a tight ventilator and production method
View Patent ↗Disclosed is a computer containing electronic components incorporating a liquid-tight and gas-permeable ventilator, including, on a part of the computer, a unit for protecting the ventilator against liquid spraying, which is created by stamping sheet metal making up the part receiving the ventilator, the protection unit being placed on one of the edges of the sheet metal part and then being folded onto the ventilator in order to make up, for the latter, a shield against liquid spraying. Also disclosed is the associated method.
1. A computer ( 10 ) containing electronic components incorporating a liquid-tight and gas-permeable ventilator ( 50 ), including, on a part ( 20 ) of said computer ( 10 ), a means ( 100 ) for protecting said ventilator ( 50 ) against liquid spraying, which is created by stamping sheet metal making up the part ( 20 ) receiving said ventilator ( 50 ), said protection means ( 100 ) being placed on one of the edges of the sheet metal part ( 20 ) and then being folded onto the ventilator ( 50 ) in order to make up, for the latter, a shield against liquid spraying.
2. The computer ( 10 ) as claimed in claim 1 , wherein the computer ( 10 ) is made up of a cover ( 20 ) and of a casing ( 30 ) and wherein the cover ( 20 ) is created by stamping sheet metal and incorporates the ventilator ( 50 ).
3. The computer ( 10 ) as claimed in claim 2 , wherein the ventilator ( 50 ) is created by stamping the sheet metal of the cover ( 20 ) and makes up a single piece with the latter.
4. The computer ( 10 ) as claimed in claim 2 , wherein the ventilator ( 50 ) incorporated in the cover ( 20 ) is a piece attached to the cover ( 20 ).
5. The computer ( 10 ) as claimed in claim 2 , wherein the protection means ( 100 ) is housed in a recess ( 110 ) once folded onto the ventilator ( 50 ), so as not to increase the overall dimensions of the part receiving the ventilator ( 50 ).
6. A motor vehicle incorporating a computer ( 10 ) as claimed in claim 2 and receiving an on-board electronic computer used for the operation of said motor vehicle.
7. The computer ( 10 ) as claimed in claim 1 , wherein the ventilator ( 50 ) is created by stamping the sheet metal of the cover ( 20 ) and makes up a single piece with the latter.
8. The computer ( 10 ) as claimed in claim 7 , wherein the protection means ( 100 ) is housed in a recess ( 110 ) once folded onto the ventilator ( 50 ), so as not to increase the overall dimensions of the part receiving the ventilator ( 50 ).
9. A motor vehicle incorporating a computer ( 10 ) as claimed in claim 7 and receiving an on-board electronic computer used for the operation of said motor vehicle.
10. The computer ( 10 ) as claimed in claim 1 , wherein the ventilator ( 50 ) incorporated in the cover ( 20 ) is a piece attached to the cover ( 20 ).
11. The computer ( 10 ) as claimed in claim 10 , wherein the protection means ( 100 ) is housed in a recess ( 110 ) once folded onto the ventilator ( 50 ), so as not to increase the overall dimensions of the part receiving the ventilator ( 50 ).
12. A motor vehicle incorporating a computer ( 10 ) as claimed in claim 10 and receiving an on-board electronic computer used for the operation of said motor vehicle.
13. The computer ( 10 ) as claimed in claim 1 , wherein the protection means ( 100 ) is housed in a recess ( 110 ) once folded onto the ventilator ( 50 ), so as not to increase the overall dimensions of the part receiving the ventilator ( 50 ).
14. A motor vehicle incorporating a computer ( 10 ) as claimed in claim 13 and receiving an on-board electronic computer used for the operation of said motor vehicle.
15. A motor vehicle incorporating a computer ( 10 ) as claimed in claim 1 and receiving an on-board electronic computer used for the operation of said motor vehicle.
16. A method of production by stamping sheet metal of a part ( 20 ) of a computer ( 10 ) containing electronic components and incorporating a liquid-tight and gas-permeable ventilator ( 50 ), characterized in that it comprises the following steps:
stamping the part ( 20 ) of the computer ( 10 ) in the sheet metal, reserving on at least one of the edges of the cut sheet metal an additional surface of sheet metal close to the location of the ventilator ( 50 ),
shaping the part ( 20 ) of the computer ( 10 ),
bending the additional surface close to the location of the ventilator ( 50 ) so as to make up, for the latter, a shield against liquid spraying.
17. The production method as claimed in claim 16 wherein the part ( 20 ) of the computer ( 10 ), which computer is made up of a casing ( 30 ) and of a cover ( 20 ), which receives the ventilator ( 50 ) and the shield is the cover ( 20 ) thereof.
18. The production method as claimed in claim 17 wherein the ventilator ( 50 ) is created by stamping the sheet metal of the cover ( 20 ) and makes up a single piece with the latter.
19. The production method as claimed in claim 16 wherein the ventilator ( 50 ) is created by stamping the sheet metal of the cover ( 20 ) and makes up a single piece with the latter.
20. The production method as claimed in claim 16 wherein the ventilator ( 50 ) is a piece attached to the cover ( 20 ).
