Heat exchanger support structure and heat exchanger supporting method

Abstract

A heat exchanger support structure has a first heat exchanger, a second heat exchanger, and a radiator core support for supporting the first heat exchanger. The first heat exchanger has a lower supporting pin projecting downward from a lower portion of the first heat exchanger. The second heat exchanger arranged in front of the first heat exchanger and having an upper portion and a lower portion The upper portion is supported by the radiator core support and the lower portion is supported by the lower supporting pin of the first heat exchanger so that the lower supporting pin restricts a horizontal movement of the second heat exchanger and allows a vertical movement of the second heat changer.
