Patent JP-H07127990-A (JP)
Title: Heat exchanger
Inventor: SASAKI KENICHI
IPC: F28F9/02
Filed: 1993-11-02
Abstract: PURPOSE:To eliminate a troublesome assembling work and improve the strength of a tank without increasing the number of parts by a method wherein a wall of a non-connected part of at least one of tank tube of an upper tank and a lower tank is constructed by a member having a circular arc section. CONSTITUTION:Refrigerant fed from an inlet pipe 7 is circulated within a system and a heat exchanging operation is carried out between it and surrounding air passing through a plurality of tubes 3. As the refrigerant is circulated within the system, an inner pressure applied to an upper tank 1 and a lower tank 2 is increased. However, a non-contacted wall of a tube of the tank, an upper wall 1a and a lower wall 3b are constructed by a plurality of members having a circular arc section. The members having an arcular section have a strength preventing a quite high deformation against a pressure applied from a central part of the arc, i.e., the inside part of the tank. Accordingly, the wall of the non-connected side of the tube is effectively reinforced by the circular arc section by itself without using any other reinforcing members and then an anti- pressure strength of the tank can be improved.
