Abstract: The present disclosure relates to a composite fin structure for a radiator, comprising a plurality of elongated corrugated fins arranged in parallel and spaced apart from each other. Air flow channels are defined between the opposing main side surfaces of adjacent fins, allowing cooling air to flow therethrough along a longitudinal direction of the fins. It is characterized in that each fin comprises a first corrugated fin section having a first waveform and a second corrugated fin section having a second waveform, with extending directions of the first and second waveforms being consistent with the longitudinal direction of the fin. A fin density of the first waveform is greater than that of the second waveform, and the first corrugated fin section extend at least in an inlet side region of each air flow channel. This invention also relates to a radiator with the composite fin structure, as well as a fuel cell cooling system comprising the radiator.

Abstract: The present disclosure relates to a fin structure for a radiator, comprising a plurality of elongated fins arranged in parallel and spaced apart from each other, wherein an air flow channel is defined between opposing main side surfaces of adjacent two fins for allowing cooling air to flow therethrough along a fin longitudinal direction; a corrugated section extending in the fin longitudinal direction is formed on each fin; and the fins are arranged such that for adjacent fins, the peaks of the corrugated sections are aligned in the arranging direction of the fins and troughs of the corrugated sections are aligned in the arranging direction of the fins, characterized in that, in each wavy unit of the corrugated section, the wave peak is offset from a central plane between two adjacent wave troughs and approaches an inclined slope extending between a wave peak and a wave trough in an adjacent wavy unit of a corrugated section of an adjacent fin. The present disclosure also relates to a radiator with said fin structure, as well as a fuel cell cooling system comprising such a radiator.
