Abstract: An exemplary air heat exchanger is an engine configuration including a front heat exchange unit including a front air-to-air intercooler configured to receive a stream of air, and a front radiator connected to the front air-to-air intercooler. The engine configuration also includes a rear heat exchange unit including a rear radiator and a rear air-to-air intercooler connected to the rear radiator. An internal combustion engine is located such that the rear air-to-air intercooler is located between the engine and the front air-to-air intercooler.

Abstract: An air heat exchanger comprising a front-end heat exchanger (101), a fan (8), a ventilating duct (11), a back-end heat exchanger (102), a fan power source (20) and a fan drive shaft (7), wherein the front-end heat exchanger (101) and the back-end heat exchanger(102) are connected in series by a heat exchanger connecting tube (105); the front-end heat exchanger (101) and the back-end heat exchanger (102) can each consist of one or more overlaid heat exchange units, respectively arranged upstream and downstream of a fan channel; the fan (8) is set up inside the ventilating duct (11) of the heat exchanger, adopting two-process cross-flow and counterflow heat exchange. The air heat exchanger features a simple structure, mature technology, high heat exchange efficiency, a compact structure and a fan with low power consumption and a low noise level, and of low cost.
