Title: CROSSFLOW HEAT-EXCHANGERS
Abstract:
A crossflow heat-exchanger (100) has first and second sets of fluid-flow channels (103, 104) arranged such that each set crosses the other to afford heat- exchange between cooling air in the first set (103) (seen as rows) and hot air in the second set (104) (seen as columns), without the cooling air and the hot air contacting one another. A first series of fans (101) causes flow of the external cooling air through the rows (103). A second series of fans (102) causes flow of the internal hot air through the columns (104). External and internal fan controllers (124, 125) control the speed of each fan (101, 102) independently such that external cooling air flows through different rows (103) at different rates and internal hot air flows through different columns (104) at different rates.
