Process of making a ceramic heat exchanger element

Details

Inventors: Danis, Louis J.;
Assignee: Williams International Corporation (Walled Lake, MI)
Primary Examiner: Weston; Caleb
Assistant Examiner:
Attorney, Agent or Firm: Lyon; Lyman R.

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.

DETAILED DESCRIPTION The invention relates to a recuperative heat exchanger, and a process for the manufacture thereof, comprising ceramic elements orientated to provide a plurality of cross flow channels separated by relatively thin walls.
The heat exchanger and disclosed manufacturing process insure separation of the exhaust and intake gases that are in heat exchange relationship with each other.
The heat exchanger elements are supported with respect to each other in a manner that compensates for thermal expansion.
