Abstract
The heat exchanger according to the invention consists of two flat or slightly incurved parallel surfaces formed in two sheets of metal (2) and (3). The longitudinal edge pieces (8) and (9) and transverse edge pieces (12) and (13) have rounded edges. The entire exterior surface is coated with enamel. These exchangers may be used in groups of several parallel units arranged inside a tubular body, or they may be disposed in a radiating pattern inside a cylindrical tank in a chemical reactor, forming a complex exchanger. This invention is of interest to manufacturers of industrial heat exchangers, particularly exchangers designed for the chemcial, pharmaceutical or agricultural/food industries.
Claims19
A flat, one-piece enamel heat exchanger comprising:
- two sheets of metal tightly sealed to each other at the borders of their longitudinal edge pieces and transverse edge pieces, defining an interior space, either open or compartmented, opening on the outside onto at least one transverse edge piece through at least one single or coaxial fluid communication, connected to an exterior fluid distribution network;
- wherein the longitudinal edge pieces and the transverse edge pieces are covered with rounded reinforcing pieces, and the transverse profile of the exchanger is either flat or slightly curved, and an entire exterior surface of the body of the exchanger is continuously enameled with no interruption in the enameled coating extending to the connections with the exterior fluid distribution network.
A plurality of flat, one-piece enamel heat exchangers, each heat exchanger comprising:
- two sheets of metal tightly sealed to each other at the borders of their longitudinal edge pieces and transverse edge pieces defining an interior space, either open or compartmented, opening on the outside onto at least one transverse edge piece through at least one single or coaxial fluid communication, connected to an exterior fluid distribution network;
- the longitudinal edge pieces and the transverse edge pieces are covered with rounded reinforcing pieces, and the transverse profile of the exchanger is either flat or slightly curved, and an entire exterior surface of the body of the exchanger is continuously enameled with no interruption in the enameled coating extending to the connections with the exterior fluid distribution network;
- wherein the plurality of heat exchangers are disposed in parallel to one another, one beside the other, and maintained in place and separated form one another by transverse supports, and disposed inside a tubular envelope with a completely enameled inside area, forming a compact heat exchanger.
A plurality of flat, one-piece enamel heat exchangers, each heat exchanger comprising two sheets of metal tightly sealed to each other along a border delineated by longitudinal edge pieces and transverse edge pieces, the two sheets of metal defining one of an open and compartmented interior space having an opening to at least one transverse edge piece through at least one of a single and coaxial fluid connection communicating with an exterior fluid distribution network;
- the longitudinal edge pieces and the transverse edge pieces are covered with rounded reinforcing pieces, and a transverse profile of the heat exchanger is either flat or slightly curved, and an entire exterior surface of the body of the heat exchanger is continuously enameled with no interruption in an enameled coating extending to the connections with the exterior fluid distribution network;
- and
- wherein the plurality of heat exchangers are arranged upright and substantially radially around a shaft of a central agitator of a tank of a chemical reactor.
