Title: Mounting and retaining exchanger tubes
IPC: F28F9/04
Filed: 1976-03-17
Abstract: System for mounting and retaining the ends of tubes in a heat exchanger bunder, consists of forming the ends of neighbouring tubes to give mating surfaces. These ends are then joined together and sealed. They can be joined either in a square framework or be offset. For elliptical tubes, the ends are flattened along the shorter axis of the ellipse so as to form a rectangle. The short edges of adjoining tubes are then pressed together and held in position. Similarly rectangular ends are formed on circular tubes and these are pushed together. The same principle applies to oval, square or rectangular tubes. For use in heat exchanger construction, esp. where the medium to be heated flows through the tubes and the other fluid flows around them. The system is cheaper in mfr. of tube plates and allows a construction more resilient to expansion.
