Abstract
A heat transfer apparatus especially useful for cooling electronic components has a frame with a channel for the flow of heat transfer liquid, a flexible sheet connected to the frame, and a thermal via coupled to the sheet. As fluid flows through the channel, the sheet and via move outwardly for contact with the component to be cooled. A cover structure extends across the frame adjacent the via and limits outward movement of the sheet. The cover structure also prevents damage to the sheet when the apparatus is handled.
