A cooling arrangement, for cooling power devices such as semiconductor power devices, comprises a housing having sidewalls around the periphery of a baseplate, and a capping plate opposing the baseplate. The housing forms a cavity through which cooling fluid may flow between an inlet and an outlet disposed in the housing. Within the cavity is provided one or more baffles that are arranged to force the cooling fluid flowing between the inlet and outlet along a labyrinthine path through the cavity. At least one of the baffles comprises at least one through-hole, which permit cooling fluid to pass there through from one side of the baffle to the other.

A plate heat exchanger and methods of construction and use which allow the plate assemblies used in the exchanger to be easily cleaned and maintained and which allow the plate assemblies to be individually and separately removed from the exchanger for cleaning or maintenance while the exchanger remains online and while the other plate assemblies in the plate heat exchanger continue to operate.

A heat transfer system (e.g., a heat pump) can include at least a first fin array and at least a first pump disposed in fluid communication with the first fin array and configured to cause a first fluid to flow through the first fin array. The system can include at least a first heat transfer layer attached to and/or in thermal communication with the first fin array. The first heat transfer layer can define a second fluid flow path therein for a second fluid to flow fluidly isolated from the first fluid. The first heat transfer layer and the first fin array can be configured to cause heat transfer between the first fluid and the second fluid.

There is disclosed a heat exchanger comprising at least one set of channels having a proximal end and a distal end, the set of channels comprising: a first channel defined by a first skin and a wall; and a second channel defined by a second skin and the wall, wherein the wall located between the first channel and the second channel comprises a first at least one aperture to allow fluid to pass through the wall from the first channel to the second channel.

A heat exchanger such as a cold plate or ICE plate has an integrated electric heating element provided on an external heater support surface of the heat exchanger. The external heater support surface is directly opposite to an internal surface of the heat exchanger which at least partly defines one or both of the inlet manifold and the outlet manifold. A thermal management system for a vehicle having a plurality of rechargeable battery units includes a circulation loop for circulating a first volume of the heat transfer fluid, and a plurality of battery heat exchangers, including a first heat exchanger with an integrated electric heating element. A sub-loop of the circulation loop includes the internal fluid flow passage of the first heat exchanger, and is adapted for a second, smaller volume of the heat transfer fluid.

A manifold structure is formed using ultrasonic additive manufacturing and machining. The manifold structure includes a body having a base plate and a cover plate that define a flow passage therebetween, and a plurality of walls that segment the flow passage into a plurality of channels, wherein each of the walls has a height extending from the base plate to the cover plate and a non-linear length that is elongated relative to a width of the wall and extends in a direction normal to the height of the wall. The walls are wavy in shape to provide enhanced rigidity and stiffness during lamination over the channels.

A PCM-based heat exchanger is disclosed, said phase change material (PCM)-based heat exchanger comprising: a) a case having insulated walls comprising an inlet and an outlet; and b) a plurality of modules comprising a support structure containing a phase change material, wherein said modules are arranged within said case in a way as to define a fluidic path connecting said inlet with said outlet. Another object relates to an apparatus, wherein said apparatus is an incubator, such as an infant incubator or a chicken/eggs incubator, or a glove box, characterized in that it comprises the PCM-based heat exchanger operatively connected with a hood defining an insulating compartment, a fan adapted for injecting an air flow into said PCM-based heat exchanger and a system to regulate the air temperature inside the hood.

An electric heating device for a motor vehicle has a first housing part which surrounds a first circulation chamber and a second housing part which surrounds a second circulation chamber. The first and second circulation chambers abut against each other. A PTC heating device is interposed between the first and second housing parts. The PTC heating device comprises a first cover element covering the first circulation chamber of the first housing part and a second cover element covering the second circulation chamber of the second housing part. At least one PTC element is provided between the first and the second cover elements. An electrode field is provided on the interior side of each of the respective cover elements and is electrically conductively contacted on the PTC element.
