A substantially planar heat exchanger for regulating the temperature of objects using a fluid coolant includes a bottom plate, a top plate, a fin insert sealed therebetween and a coolant inlet and outlet. The fin insert may include a plurality of substantially flattened omega-shaped or teardrop-shaped fins, which enhances the transfer of heat from the top and/or bottom plates into the fin insert. The omega-shaped fin inserts enhance the contact surface area between the plates and the insert to improve thermal migration therebetween. The fin insert may be constructed, for example, by forming convolutions in a sheet of metal, and compressing the convolutions laterally inwardly and vertically inwardly.

There is disclosed a heat exchanger for regulating the temperature of a battery pack. The battery pack comprises at least one array of battery cells arranged in a row. An end surface of each battery cell lies adjacent the outer surface of a heat exchanger core so that the end surface lies opposite at least a pair of channels, and suitably at least one first fluid channel carrying fluid at a first direction and at least one second fluid channel carrying fluid in a second opposite direction. The heat exchanger may have inlet and outlet fluid connections located at the same end, or at opposite ends of the heat exchanger core. First and second end housings connect at first and second ends of the heat exchanger core. A plurality of partition walls within the manifolds determine the flow path of fluid within the heat exchanger core.
A heat exchanger for regulating the temperature of objects includes two coolant ports that can interchangeably serve as either a coolant inlet or a coolant outlet. The heat exchanger includes sealedly engaged top, middle, and bottom plates that form passageways that distribute coolant through the heat exchanger. A top manifold is formed between the top and middle plates and is fluidly coupled with a first port, while a bottom manifold is formed between the bottom and middle plates and is fluidly coupled with a second port. The top and bottom manifolds are configured such that, during operation, coolant can be directed from the first port to the second port, or vice versa, thereby enabling the heat exchanger to operate bidirectionally—without materially affecting the temperature regulation effects of the heat exchanger. In this manner, the same heat exchanger construction can be used in multiple orientations within a thermal management system.

A heat exchanger for regulating the temperature of objects using coolant includes a top plate, a middle plate, and a bottom plate that are sealedly engaged for circulation of coolant, and collectively form a stacked cooling block. The heat exchanger includes a plurality of coolant flow channels, including sets of feed and return channels, which are formed between the top, middle, and bottom plates, and which operably cool one or more cooling surfaces of the heat exchanger. An inlet manifold of the heat exchanger distributes coolant through a plurality of distribution apertures, into a set of coolant feed channels. The coolant feed channels are fluidly connected with a set of coolant return channels, which in turn direct coolant toward and into an outlet manifold. The inlet manifold is adapted to substantially evenly distribute fluid through the plurality of coolant flow channels, by way of one or more flow-balancing elements integrated therewith.

An improved heat exchanger suitable for use as a pre-cooler in an internal combustion engine exhaust gas recirculation system includes an inner heat exchange tube for exchanging heat between a gas and a coolant. A tubular outer body surrounds at least part of the inner heat exchange tube. Coolant flows through a cavity formed between the outer surface of the inner heat exchange tube and the inner surface of the tubular outer body, cooling the gas flowing through the inner heat exchange tube. The inner heat exchange tube surrounds a rolled, cylindrically-shaped corrugated sheet of material forming a plurality of fins. At least one of the fins is in contact with an inner surface of the inner heat exchange tube. The tubular outer body surrounds two or more inner heat exchange tubes, each inner heat exchange tube surrounding a respective plurality of fins.

A heat exchanger (100) for an exhaust gas recirculation system includes one or more rigid tubes (103), each having one or more internal cooling fins (111) that act as heat exchange surfaces to transfer heat from a gas to the walls of the rigid tubes. The rigid tubes are cooled by a liquid coolant contained within an outer jacket (113) surrounding the tubes. The rigid tubes may be straight and smooth, and may be alternated with one or more bellows sections (108, 104) which provide flexibility to the heat exchanger.
