  • Heat pipe heat exchanger for large scale integrated circuits
    Patent number: 4633371
    Abstract: Disclosed is a heat pipe heat exchanger for large scale integrated circuits. The heat pipe means is mounted on the substrate which supports the integrated circuit. The heat is conducted by the heat pipe means away from the integrated circuit to a surface area for dissipating heat. A plenum supplies a cooling medium across the surface area of the heat pipe means for removing the heat. An enclosing means for enclosing the surface area of the heat pipe means forms channels across the surface area for receiving the cooling medium supplied from the plenum.
