While extensive research has focused on improving the efficiency and performance of heat exchangers (HXs), identifying underlying causes degradation remains equally important. Flow temperature non-uniformities are among most critical factors affecting performance, often reducing thermo-hydraulic by approximately 5–10%. These commonly manifest as thermal inconsistencies, airflow maldistribution, uneven refrigerant distribution. Researchers have observed a notable degradation—up to 27%—due flow maldistribution. Therefore, clear understanding their effects is essential for developing effective mitigation strategies enhance system performance. Despite progress in this area, few studies systematically classified dominant associated with specific HX types. This article presents two-decade review causes, impacts, approaches related across different configurations. The primary objective identify form non-uniformity each category. specifically examines plate (PHXs), finned tube (FTHXs), microchannel (MCHXs), printed circuit (PCHXs). It also discusses mathematical models designed account HXs. concludes key gaps outlining future directions support development more reliable energy-efficient
