BI-CHANNEL COOLANT TUBE HAVING CROSSOVER CHANNELS TO ALLOW COOLANT INTERACTION

摘要

A bi-channel tube for use in a heat exchanger is disclosed having a passageway or window formed in the common wall or divider separating the adjacent channels. This arrangement permits a controlled amount of interaction of the fluids flowing in the adjacent channels in the bi-channel tube. The bi-channel coolant tube includes a first fluid-carrying channel, a second fluid-carrying channel, a common wall or divider separating the first fluid-carrying channel from the second fluid-carrying channel, and at least one fluid-passing passageway or window formed in the common wall or divider. The fluid-passing passageway or window is preferably an elongated window that is formed along the long axis of the bi-channel coolant tube. The bi-channel coolant tube may be composed of a metal such as aluminum, including aluminum alloy, and steel, including stainless steel.
