Secondary side heatsink techniques for optical and electrical modules
A module for use in a hardware platform for networking, computing, and/or storage includes a printed circuit board assembly having a primary side and a secondary side, wherein the primary side includes more physical space, in a vertical direction extending out from the printed circuit board assembly, than the secondary side; electrical and/or optical components disposed on the primary side of the printed circuit board assembly; and a secondary side heatsink located on and extending from the secondary side, wherein the secondary side heatsink is disposed to one of i) an electrical and/or optical component disposed on the secondary side, and ii) an optical component disposed on the primary side, for thermal management.
1. A module for use in a hardware platform for networking, computing, and/or storage, the module comprising:
a printed circuit board assembly having a primary side and a secondary side, wherein the primary side includes more physical space, in a vertical direction extending out from the printed circuit board assembly, than the secondary side;
electrical and/or optical components disposed on the primary side of the printed circuit board assembly; and
a secondary side heatsink located on and extending from the secondary side, wherein the secondary side heatsink is disposed to one of the optical components disposed on the primary side, for thermal management,
wherein the secondary side heatsink is a coin-style heatsink that extends through the printed circuit board assembly to the one of the optical components disposed on the primary side, and wherein the coin-style heatsink has an adjustable height on the secondary side via set screws and cylindrical posts.
2. The module of claim 1 , wherein the primary side includes interface components for connectivity to data and/or power connections in the hardware platform.
3. The module of claim 1 , wherein the one of the optical components disposed on the primary side is a pluggable module.
4. The module of claim 3 , further comprising
a cage disposed on the primary side, for the optical component, wherein a hole is located in the printed circuit board assembly where the secondary side heatsink is able to contact the pluggable module.
5. The module of claim 3 , wherein the secondary side heatsink is a coin-style heatsink that protrudes from the secondary side to the optical component.
6. The module of claim 3 , further comprising
a primary side heatsink for the optical component, wherein the primary side heatsink is fixedly attached at one pivot point and attached to a faceplate at an opposite point via spring tabs.
7. A module for use in a hardware platform for networking, computing, and/or storage, the module comprising:
a printed circuit board assembly having a primary side and a secondary side, wherein the primary side includes more physical space, in a vertical direction extending out from the printed circuit board assembly, than the secondary side;
electrical and/or optical components disposed on the primary side of the printed circuit board assembly;
a secondary side heatsink located on and extending from the secondary side, wherein the secondary side heatsink is disposed to one of the optical components disposed on the primary side, for thermal management, wherein one of the optical components disposed on the primary side is a pluggable module; and
a primary side heatsink for the pluggable module, wherein the primary side heatsink is fixedly attached at one pivot point and attached to a faceplate at an opposite point via spring tabs.
8. The module of claim 7 , wherein the primary side includes interface components for connectivity to data and/or power connections in the hardware platform.
9. The module of claim 8 , further comprising
a cage disposed on the primary side, for the optical component, wherein a hole is located in the printed circuit board assembly where the secondary side heatsink is able to contact the pluggable module.
10. The module of claim 8 , wherein the secondary side heatsink is a coin-style heatsink that protrudes from the secondary side to the optical component.
