Abstract
A heat sink assembly including a first member having a heat transfer surface adapted to directly contact a device to be cooled; a second member including coolant channels and a separate fluid channel; and a connection which at least partially mechanically connects the first member to the second member. The connection includes three bellows forming three conduits between the channels in the second member and the first member. A second one of the bellows and a third one of the bellows are located inside a first one of the bellows.
Claims21
A heat sink assembly comprising:
- a first member having a heat transfer surface adapted to directly contact a device to be cooled;
- a second member comprising coolant channels and a separate fluid channel;
- and
- a connection which at least partially mechanically connects the first member to the second member, wherein the connection comprises three bellows forming three conduits between the channels in the second member and the first member, and wherein a second one of the bellows and a third one of the bellows are located inside a first one of the bellows.
A heat sink assembly comprising:
- a first member adapted to directly contact a device to be cooled;
- a second member comprising coolant channels and a pneumatic fluid channel;
- and
- a first bellows between the pneumatic fluid channel in the second member and the first member, wherein the bellows and the first member are adapted to use pneumatic fluid to push the first member against the device.
A method comprising:
- providing a first member with a heat transfer surface adapted to directly contact a device to be cooled;
- providing a second member comprising coolant channels and a separate pneumatic fluid channel;
- and
- connecting the first member to the second member by a connection comprising three bellows forming three conduits connected to the channels in the second member, wherein a second one of the bellows and a third one of the bellows are located inside a first one of the bellows.
A method comprising:
- providing a heat sink assembly with a first member connected to a second member by a plurality of bellows, wherein the second member comprises coolant channels and a pneumatic fluid channel, wherein the pneumatic fluid channel is connected to the first member by a pneumatic fluid conduit formed by a first one of the bellows separate from coolant conduits formed by a second and a third one of the bellows, and wherein the first member comprises a heat transfer surface for directly contacting a device to be cooled;
- aligning the heat transfer surface of the first member on the device;
- and
- after the heat transfer surface has been aligned on the device, increasing pressure of the first member against the device by pneumatic fluid from the second member to the pneumatic fluid conduit.
