WINDROWER TRACTOR WITH PARALLEL HEAT EXCHANGERS FOR COOLING OF ENGINE AND ASSOCIATED FLUIDS

摘要

An agricultural tractor having its engine longitudinally spaced along its frame from the operator cabin features at least two heat exchangers carried on the frame at a position located longitudinally between the operator cabin and the engine to perform air-cooling of at least one fluid associated with the engine. The two heat exchangers are arranged in parallel so as to each accept an intake stream of ambient air that is independent of a discharge stream of exhaust air from the other heat exchanger. Accordingly, each heat exchanger uses the coolest air possible to maximize the cooling potential of the system. The discharge stream of air from the heat exchangers is exhausted rearward to avoid recirculation of this heated air as the machine moves forward, and to direct the exhaust air past the engine for further cooling effect.
