Abstract
A heat exchanger is disclosed. Side plates (4) each include a base portion (41), in contact with fins (11), and side wall portions (42) extending from the base portion (41) in the direction Y in which tubes (10) are stacked. The side wall portions (42) are formed with a bent deforming portion (421) to facilitate extension/shrinkage, of the side wall portions (42), in the longitudinal direction (X) of the tubes (10). The base portion (41) is formed with a pair of hooks (411) extending toward the surface of the bent deforming portion (421) in opposed relation to the base portion (41). In the case where the base portion (41) tends to be displaced, the hooks (411) come into contact with the bent deforming portion (421) to thereby suppress or prevent the displacement of the base portion (41).
Claims2
A heat exchanger comprising:
- a core unit including a multiplicity of tubes and a multiplicity of fins stacked alternately with each other;
- tanks arranged at the ends in the longitudinal direction of the tubes of the core unit and communicating with the multiplicity of the tubes;
- and
- side plates arranged at the ends in the stacking direction of the tubes of the core unit and having the ends thereof coupled to the tanks;
- wherein the side plates each include a base portion in contact with the fins and side wall portions extending from the base portion in the stacking direction of the tubes;
- wherein the side wall portions are each formed with a bent deforming portion to facilitate the extension and shrinkage of the side wall portions in the longitudinal direction of the tubes by the bending deformation;
- wherein the base portion is divided in the longitudinal direction of the tubes by a slit formed at a position corresponding to the bent deforming portion;
- and
- wherein a pair of hooks extending toward the end surface of the bent deforming portion in opposed relation to the base portion are formed at the slit side ends of the divided parts, respectively, of the base portion.
