Heat exchanger for horizontal installation under a motorcycle engine

摘要

A motorcycle has a heat exchanger adapted to be installed on the motorcycle in a substantially horizontal orientation. Also, the heat exchanger is adapted to be installed on the motorcycle beneath the engine, crankcase, oil pan and/or gearbox without substantial vertical orientation and not attached directly to the engine, except by cooling fluid connectors. Preferably, the heat exchanger is made with finned tubular core elements. The heat exchanger is installed in a suspended manner beneath the motorcycle, so that cooling air may pass over its top and bottom surfaces. Preferably, the heat exchanger is an oil intercooler.

主权项

1. A motorcycle with an engine and with an engine cooling circuit, the engine having a bottom side which faces the ground when the motorcycle is oriented in an upright position, the motorcycle comprising:
a motorcycle frame; fluid connectors for the engine cooling circuit; and, a heat exchanger having a core including finned tubular core elements fluidly connected to the engine cooling circuit via said fluid connectors for the engine cooling circuit, the heat exchanger core further having a generally planar top area defining a top plane and a generally planar bottom area defining a bottom plane, the heat exchanger being installed on the motorcycle frame and being suspended directly beneath the engine such that each of said top area and of said bottom area of the core has a substantially horizontal orientation when the motorcycle is in an upright position and such that a space is formed between the top area of the core and the bottom side of the engine so that cooling air may pass over the top area and over the bottom area of the core and so that cooling air may also pass through said space between the top area of the core and the bottom side of the engine, at least when the motorcycle is in motion; wherein the heat exchanger is not attached directly to the engine except by said fluid connectors for the engine cooling circuit.
