A method includes providing a first metal sheet and a second metal sheet, printing a plurality of channels on the first metal sheet, bonding the first metal sheet and the second metal sheet to each other to obtain a fin body, bending a first portion of the fin body to be transverse to a second portion of the fin body, separating the first metal sheet and the second metal sheet from each other to form the plurality of channels, introducing working fluid in the plurality of channels, and sealing the first metal sheet and the second metal sheet.

A cooling system for a motor vehicle may include a first circuit, a second circuit, a first heat exchanger incorporated in the first circuit, and a second heat exchanger incorporated in the second circuit. The first heat exchanger and the second heat exchanger may be flowed through by ambient air and a coolant. The first heat exchanger may be arranged, relative to an airflow direction, in front of and directly adjacent to the second heat exchanger. The first circuit and the second circuit may be fluidically connected to one another at an upstream distribution point and at a downstream collection point such that a part mass flow of the coolant is flowable from the second circuit into the first circuit at the distribution point, from the first circuit into the first heat exchanger, and out of the first heat exchanger back into the second circuit at the collection point.

A thermal transfer device has a body and a fluid conduit defined in the body. The body has a thermal transfer surface configured to be placed in contact with a target component. The fluid conduit is configured for conveying fluid through the body and is thermally coupled to the thermal transfer surface.

A cooling system for an information handling system comprises a fan with a sunflower type heat exchanger having two heat exchanger bodies separated by a gap and rotationally offset an angle sized such that a fin of the first heat exchanger body is aligned relative to a channel between two adjacent fins of the second heat exchanger body. As airflow flows through channels between adjacent fins of the first heat exchanger body, the air temperature increases. Air exiting the first heat exchanger body mixes with a second airflow entering the gap between the two heat exchanger bodies and the combined airflow is cooler and turbulent for additional heat absorbing capability for improved cooling.

A flat tube for a heat exchanger may include a longitudinal-end inlet for letting a fluid into the flat tube, and a longitudinal-end outlet spaced apart from the inlet in a longitudinal direction for letting the fluid out from the flat tube. The flat tube may also include flow elements around at least a portion of which the fluid may be flowable around the flow elements in such a manner that the fluid may have a flow direction component perpendicular to the longitudinal direction. The outlet and the inlet each may be delimited on a partial cross-sectional area of the flat tube and arranged diagonally opposite one another.

An oil cooler is disclosed that comprises a base plate including a recessed portion defined by an interior wall and an exterior wall and including an inlet port and an outlet port. The base plate further includes a divider wall positioned in the recessed portion and extending between the exterior wall and the interior wall to separate the inlet port and the outlet port, a plurality of protrusions arranged in the recessed portion to provide a plurality of tortuous flow paths through which oil flows from the inlet port to the outlet port, and a first set of cooling fins formed on a surface of the base plate opposite the recessed portion. A cover plate is attached to the base plate so as to cover the recessed portion and thereby define a cavity to circulate the oil therethrough, the cover plate including a second set of cooling fins formed thereon.

A heat exchanger is provided. The heat exchanger (40) provides a first plurality of tubes (50) and a second plurality of flow passages (52) which furcate near one of the first (42) and second (44) manifolds into two or more furcated flow passages and subsequently converge to exit the heat exchanger. The plurality of furcated flow passages are intertwined, reducing the distance between flow passages (50,52) containing each fluid therebetween to improve thermal transfer. Further, the furcations create changes of direction of the fluid to re-establish new thermal boundary layers within the flow passages to further reduce resistance to thermal transfer.

A dual pass heat exchanger for cooling and dehumidifying an airstream has adjacent passes for air flow in which air flow is in opposite directions being counter-flow and parallel-flow passes. A cooling coil contains flowing chilled liquid refrigerant extending through all of the passes, and the coiling coil has fins on outer surfaces thereof for promoting efficient thermal transfer, whereby density of the fins in the counter-flow passes is greater than density in the parallel-flow passes, whereby fin density is varied in fin style, locational density, thickness and/or depth.

A plate laminated type heat exchanger includes: a plate laminated body which is formed by laminating a plurality of plates; and a heat exchanger body which includes a first header through which fluid (G) flows in from outside of the plate laminated body and a second header through which the fluid (G) flows out to the outside of the plate laminated body which are connected to the plate laminated body. Each of the plurality of plates is formed from a flat plate shape having a first surface and a second surface. The first surface is provided with a plurality of grooves defined by inner walls through which the fluid flows. The plurality of plates are connected each other so that the first surface of one of the plurality of plates is brazed to the second surface of the other one of the plurality of plates.

The present disclosure provides a heat exchanger system for a servovalve, comprising a base comprising a supply port in fluid communication with a return port, a first passage for fluid connection to a source of cooling fluid, and a second passage in fluid communication with the return port. The system further comprises one or more pipes located over a surface of the base, the one or more pipes fluidly connected between the first passage and the second passage, such that in use cooling fluid may flow from the first passage to the second passage via the network of pipes.
