AB Experimental investigation of heat-transfer enhancement in short rectangular air-flow channels with transverse protrusions and grooves of 15 specially manufactured gilled-tube water-air-flow radiators (heat exchangers) has been carried out (the channel characteristics are: l'/d = 0.183−1.695 and d*/d = 0.813−0.953). The process of rational heat-transfer enhancement is implemented in the channels; it is controlled by the l'/d and d*/d characteristics. It has been proven that the results of heat transfer enhancement in short channels are somewhat worse than those for long ones. This makes it possible to reduce the mass and volume of the radiator core (matrix) by a factor of 1.4 in comparison with short smooth channels under the same conditions.
