Mechanical assembly for regulating the temperature of an electronic device, having a spring with one slideable end
View Patent ↗A mechanical assembly, for regulating the temperature of an electronic device, includes a gimbal and a heat-exchanger which is attached to the gimbal. The gimbal includes a base member, a carrier member, and a spring which has—1) a first end with a rigid coupling to one of the base and carrier members, and 2) a second end with a slideable coupling to the remaining member. The slideable coupling prevents any gap from occurring between the heat-exchanger and the electronic device when they are pressed together.
1. A mechanical assembly for regulating the temperature of an electronic device, said mechanical assembly being comprised of:
a gimbal which includes a base member and a carrier member that is loosely held by said base member such that said carrier member can tilt and move relative to said base member by predetermined distances;
a heat-exchanger, attached to said carrier member, which has a face for pressing against said electronic device;
said gimbal further including a spring, between said base and carrier members, which urges said carrier member away from said base member; and,
said spring having a first end with a rigid coupling to only one of said base and carrier members, and having a second end with a slideable coupling to the remaining member.
2. A mechanical assembly according to claim 1 wherein said slideable coupling includes a plate which is attached to said second end of said spring and which has a surface with at least three ball bearings that roll on said remaining member and slide on said plate.
3. A mechanical assembly according to claim 2 wherein said one member with said rigid coupling is said base member, and said remaining member with said slideable coupling is said carrier member.
4. A mechanical assembly according to claim 2 wherein said one member with said rigid coupling is said carrier member, and said remaining member with said slideable coupling is said base member.
5. A mechanical assembly according to claim 2 wherein said spring is a coiled conical spring.
6. A mechanical assembly according to claim 2 wherein said spring is a coiled cylindrical spring.
7. A mechanical assembly according to claim 2 wherein said spring lies in a single plane between said base and carrier members.
8. A mechanical assembly according to claim 2 wherein said ball bearings are in respective indentations in said surface of said plate.
9. A mechanical assembly according to claim 1 wherein said slideable coupling includes a plate which is attached to said second end of said spring and which has a surface that slides on said remaining member.
10. A mechanical assembly according to claim 9 wherein said one member with said rigid coupling is said base member, and said remaining member with said slideable coupling is said carrier member.
11. A mechanical assembly according to claim 9 wherein said one member with said rigid coupling is said carrier member, and said remaining member with said slideable coupling is said base member.
12. A mechanical assembly according to claim 9 wherein said spring is a coiled conical spring.
13. A mechanical assembly according to claim 9 wherein said spring is a coiled cylindrical spring.
14. A mechanical assembly according to claim 9 wherein said spring lies in a single plane between said base and carrier members.
