Heat exchanger flow limiting baffle

摘要

A heat exchanger, such as a radiator, may transfer heat from a liquid and employ a first header tank, a second header tank, a plurality of tubes fluidly joining the first and second header tanks, and a baffle within one of the first or second header tanks. The baffle may be located in a header tank positioned substantially parallel or perpendicular to a surface upon which a vehicle employing the hear exchanger rests. The baffle may be a wall defining only one slot, a wall defining only one slot that is open through one side of the wall, a wall that defines a plurality of slots, or a wall that defines a plurality of holes. The heat exchanger may further employ fluidly isolated first and second tube and fin sections each defining a self-contained flow path for cooling different liquids. The baffle may slow coolant flow in a flow path.

主权项

1. A heat exchange system comprising:
a single-phase fluid heated by a device, wherein the fluid is a liquid coolant flowing through the heat exchanger that does not undergo a phase change during operation of the heat exchanger; a first header tank having a single inlet allowing the fluid into the first header tank from the device; a second header tank having a single outlet allowing the fluid into the device from the second header tank; a core section including:
a first plurality of tubes fluidly joining the first header tank and the second header tank, the fluid in the first plurality of tubes flowing from the first header tank to the second header tank; anda second plurality of tubes fluidly joining the first header tank and the second header tank, the fluid in the second plurality of tubes flowing from the first header tank to the second header tank; and a baffle within the first header tank, the baffle extending across an entire width and an entire depth of the first header tank to divide the first header tank into a first chamber in direct communication with the first plurality of tubes and a second chamber in direct communication with the second plurality of tubes, and a communication portion which communicates the first chamber and the second chamber, is provided in the baffle; wherein
the baffle is disposed upstream of the fluid flow in the first and second plurality of tubes;a first portion of the fluid introduced into the first header tank through the first inlet flows from the first chamber to the second header tank through the first plurality of tubes, and out from within the second header tank through the outlet; anda second portion of the fluid introduced into the first header tank through the inlet flows from the first chamber directly to the second chamber through the communication portion of the baffle, from the second chamber to the second header tank through the second plurality of tubes, and out from within the second header tank through the outlet.
