Abstract

A plate fin heat exchanger (70) has a plurality of tube sections (154, 156, 158, 160) extending across an air flowpath (98). These include a first group (154) of sections forming a leading group. The heat exchanger includes a shield (170) for preferentially shielding portions (182) of the fins (162) ahead of the leading group against debris accumulation.
