Abstract
A heat exchanger includes a corrugated metal sheet comprising a first side having a plurality of first troughs alternating with a plurality of first peaks, and a second side having a plurality of second troughs alternating with a plurality of second peaks, each trough being formed by a pair of walls, each wall separating the first side from the second side and extending from a first peak to a second peak, the troughs and peaks extending in parallel and defining a longitudinal direction. Each first peak is formed with at least one depression, the depressions in respective peaks being aligned to form at least one tube-receiving channel extending transversely to the longitudinal direction. Each depression has a contact surface formed in the first side and extending laterally over each adjacent first trough. A tube section is received in each tube-receiving channel in substantially conforming contact with the contact surfaces. The heat exchanger is manufactured using first and second fixtures having first and second sets of parallel ribs which are received in respective second and first troughs of the corrugated sheet. The first peaks are formed downward using a mandrel received throug…
