Abstract (en)
A heat exchanger for transferring heat from a fist fluid such as a cooling liquid to a second fluid such as air. The heat exchanger has one or more manifolds, a fluid inlet and a fluid outlet for allowing a fluid to enter the manifolds and be distributed to a plurality of microtubes. The microtubes are placed substantially parallel to each other and the fluid inlet and fluid outlet are fluidically connected to each other through the plurality of microtubes. The cross section of each microtube in the plurality of microtubes is non-circular and may for example be an aerofoil which may be symmetric or non-symmetric or it may be a number of microtubes connected in a tube sheet.
