A heat exchanger is provided with a unitary, single-piece structure that can be formed via 3D printing, for example. The heat exchanger includes a main body a plurality of plates stacked and integrally formed with the body. First fluid channels are defined by gaps in the material of the main body, and second fluid channels are defined by gaps in the material of the main body and are stacked with the first fluid channels in alternating fashion, separated by the plates. Each of the first fluid channels are fluidly coupled to an inlet manifold and an outlet manifold. A jumper pipe is fluidly coupled to and between an inlet port and the inlet manifold. In an embodiment, the jumper pipe is curved at one end thereof to intersect the inlet manifold at a generally perpendicular angle.

A heat exchanger is provided with a unitary, single-piece structure that can be formed via 3D printing, for example. The heat exchanger includes a main body a plurality of plates stacked and integrally formed with the body. First fluid channels are defined by gaps in the material of the main body, and second fluid channels are defined by gaps in the material of the main body and are stacked with the first fluid channels in alternating fashion, separated by the plates. Each of the first fluid channels define a first flow path, and each of the second fluid channels define a second flow path. A portion of the first flow paths overlap, and are oriented opposite to, a portion of the second flow paths. Another portion of the first flow paths overlap, and are oriented transverse to, another portion of the second flow paths.

Heat exchanger with hybrid counter cross flow

A heat exchanger is provided with a unitary, single-piece structure that can be formed via 3D printing, for example. The heat exchanger includes a main body a plurality of plates stacked and integrally formed with the body. First fluid channels are defined by gaps in the material of the main body, and second fluid channels are defined by gaps in the material of the main body and are stacked with the first fluid channels in alternating fashion, separated by the plates. Each of the first fluid channels are fluidly coupled to two manifolds, and each of the second fluid channels are fluidly coupled to two more manifolds. One of the manifolds has a reduced interior volume to control and normalize fluid flow through the heat exchanger.

A heat exchanger is provided with a unitary, single-piece structure that can be formed via 3D printing, for example. The heat exchanger includes a main body a plurality of plates stacked and integrally formed with the body. First fluid channels are defined by gaps in the material of the main body, and second fluid channels are defined by gaps in the material of the main body and are stacked with the first fluid channels in alternating fashion, separated by the plates. Each of the first fluid channels are fluidly coupled to an inlet manifold and an outlet manifold. At least one of the manifolds is provided with surface features that improve heat exchange within the manifold. The surface features may be, for example, projections such as fins that increase surface area contact between the fluid in the manifold and the interior wall of the manifold.

Heat exchanger with manifolds for heat exchange

A heat exchanger is provided with a unitary, single-piece structure that can be formed via 3D printing, for example. The heat exchanger includes a main body defining a first fluid inlet port, a first fluid outlet port, a second fluid inlet port, and a second fluid outlet port, wherein each of these fluid ports are integrally formed with the main body. A plurality of plates are stacked and integrally formed with the body. First fluid channels are defined by gaps in the material of the main body and are in fluid communication with the first fluid inlet port. Second fluid channels are defined by gaps in the material of the main body and are in fluid communication with the second fluid inlet port. The first fluid channels and the second fluid channels are interposed between the plates in alternating fashion along the stacked arrangement.

Single-piece heat exchanger

An attachment is configured to connect a first connecting plate of a vehicle component to a second connecting plate of a vehicle body. The attachment includes a body, first, second and third flanges, and a press-fit insert. The attachment is of an elastically deformable material and is configured to be inserted into first and second through holes of the first and second connecting plates. The flanges engage the connecting plates when the attachment is inserted into the through holes. The body includes a hole extending longitudinally within the body to accommodate the press-fit insert. The press-fit insert has a diameter greater than the diameter of the hole to form a snug connection between the press-fit insert and the hole. The insertion of the press-fit insert into the hole elastically deforms the attachment to urge the body radially against the connecting plates to provide a robust connection between the connecting plates.
