ABSTRACT:
A high intensity heat exchanger that uses a solid copper heat sink having a lurality of integral pins formed on one side thereof, and an electrical insulator comprised of thin film of aluminum nitride (AlN) or diamond-like carbon (C) deposited on the other side. A device to be cooled, such as a computer chip, or an infrared detector cell is secured to the insulating layer by means of a very thin film of solder. A cooling liquid is circulated to the pins through conduits which also support the heat sink. The pins have a rectangular cross section and the spacing of the pins, and the fluid velocity are optimized to provide turbulent flow around the pins. The apparatus is provided with a space under the pins for a removable orifice plate, thereby enabling the optimization of the size, shape and number of orifices for a particular application.
