Heat Exchange in a Vehicle Engine System

摘要

In some aspects of what is described here, a heat exchanger has a first fuel port and a first heat transfer fluid port at a first end of an elongate heat exchanger body. The heat exchanger has a second fuel port and a second heat transfer fluid port at a second, opposite end of the elongate heat exchanger body. The heat exchanger has a fuel flow path that is straight between the first and second fuel ports, and a heat transfer fluid flow path that is straight between the first and second heat transfer fluid ports. The heat transfer fluid flow path is parallel to, and beside, the fuel flow path. The heat exchanger includes a heat transfer wall between the fuel flow path and the heat transfer fluid flow path. Fins extend from the heat transfer wall into the flow paths.
