  • Process of making a ceramic heat exchanger element
    Patent number: 4488920
    Abstract: The disclosure relates to a process for manufacturing a ceramic heat exchanger wherein a layer of ceramic material is deposited on a fugitive carbon form by chemical vapor deposition. The carbon form is thereafter burned away from the ceramic material to form a heat exchanger element. A plurality of heat exchanger elements are bonded to one another by chemical vapor deposition to form a homogeneous ceramic heat exchanger.

  • Heat transfer element
    Patent number: 4050250
    Abstract: A heater head for use in hot gas engine is formed using improved heat transfer structures. The heat transfer structures used in the heater head are formed of an oxidation resistant enclosure enclosing a tube of high strength, gas impermeable material. A chamber is formed between the enclosure and the tube, and filled with a metal or alloy which is liquid at the operating temperature of the heater head. The structure transfers combustion heat rapidly from the oxidation resistant metal to the strong, gas impermeable tube via the liquid metal. The strong gas impermeable tube is filled with working gas, such as hydrogen or helium maintained at a high pressure.

  • Method of making a composite article for rapid heating
    Patent number: 3967013
    Abstract: A composite article capable of initially rapid heating and subsequent continuous rapid transfer of heat. The article has a core of material, preferably copper, having a minimum first predetermined value of thermal conductivity and an outer surface portion of metallic material of certain compositions such as aluminum, aluminum-rich alloy, nickel, or nickel-rich alloy. The composite article has oxidation resistance at elevated tempratures equivalent to AISI type 303 stainless steel and has a bulk thermal conductivity not less than a second predetermined value. In one embodiment the article is cup-shaped for defining an auxiliary compartment or pre-chamber for a combustion chamber of an internal combustion engine. The method includes immersing the core in a bath of molten aluminum or aluminum-rich alloy, removing the article, and heating to a temperature of substantially 800.degree.C.
