A heat exchanger comprises a stack of mutually spaced apart plates. The plates are separated by respective spacings therebetween. Alternate spacings respectively provide a flow path for a first fluid and a second fluid. The heat exchanger further comprises a first header for inflow of the first fluid and a second header for outflow of the first fluid. The first and second headers are connected to the plate stack by flexible tubular ducting means.

The invention relates to a method for controlling a temperature distribution in a heat exchanger, in which an actual temperature distribution in the heat exchanger is measured by means of at least one optical waveguide arranged in the heat exchanger, in particular in the form of a glass fiber, light being launched into the optical waveguide and light that is scattered in the optical waveguide being evaluated for determining the actual temperature distribution, and at least one flow of a fluid medium that is carried in the heat exchanger being controlled in such a way that the actual temperature distribution is made to approximate a pre-defined target temperature distribution. The invention also relates to a device for carrying out a method for controlling a temperature distribution in a heat exchanger.

The invention concerns a heat exchanger having an exchange body having first passages for the flow of a first fluid and second passages for the flow of a second fluid exchanging heat with the first fluid, a first inlet manifold for introducing the first fluid into the first passages, a first outlet manifold for discharging the first fluid from the first passages). The heat exchanger also includes an inlet filter arranged facing the inlet surface of the exchange body, and/or an outlet filter arranged facing the outlet surface of the exchange body, the inlet filter and/or the outlet filter having a sheet metallic material selected from a metal gauze, a non-woven fabric of metallic fibres, a sintered metallic powder or sintered metallic fibres.

A fluid flow-path device facilitates a maintenance operation to remove a foreign substance adhered to a member, to prevent passage of the foreign material. The fluid flow-path device has a distribution header including a partition member and a header body in a flow-path formation body. The partition member partitions a distribution space of the distribution header into an upstream-side space that communicates with a supply opening in the header body, and a downstream-side space that communicates with a plurality of flow paths in the flow-path formation body. The partition member includes a region that prevents a foreign substance in a fluid from flowing from the upstream-side space to the downstream-side space, while allowing the fluid to flow. The header body has an opening that allows a washing fluid to flow into the downstream-side space, and an opening that allows the washing fluid to be discharged from the upstream-side space.

An Integrated Hybrid Compact Fluid Heat Exchanger is disclosed. An example embodiment includes: a micro-channeled plate for a stream of a working fluid, the micro-channeled plate being diffusion bonded or brazed with a cover plate; and a fin assembly brazed, diffusion bonded, or welded to the micro-channeled plate. Other embodiments include a fan or blower coupled to the Integrated Hybrid Compact Fluid Heat Exchanger via air ducting or close coupling.

A heat exchanger includes a stack of flow conduits. Each flow conduit is configured to conduct a fluid. Parting sheets separate adjacent flow conduits in the stack, providing heat transfer between them. Each of the flow conduits includes vanes extending along a vane path and between top and bottom parting sheets. The vanes are separated from one another, thereby creating flow channels. Each flow conduit also includes a plurality of flow modifiers, each adjacent to a corresponding leading edge of a corresponding vane, so as to cause a disrupted portion of a fluid flow to be incident upon the corresponding leading edge. Each of the flow modifiers includes an aerodynamic portion and a gap portion. The aerodynamic portion extends from at least one of the top and bottom parting sheets. The aerodynamic portion does not connect the top and bottom parting sheets due to the gap portion.

A cold plate is provided and includes: a housing disposed with a chamber; a base combined with the housing to form a working space separated from the chamber but connected with the chamber through an interconnecting structure to allow a working medium to flow within the chamber and the working space; a heat transfer structure disposed on the inner side of the base; and a pump disposed within the working space to drive the working medium in the working space. As such, the cold plate can provide better heat dissipation performance.

Various embodiments include heat exchangers and methods of making heat exchangers from a series of stacked plates each made of two foil sheets bonded together in bonding locations forming fluid flow passages between the foil sheets in regions where the foil sheets are not bonded. An inlet port and an outlet port located at opposite ends of the planar extent of the two foil sheets extend through the foil sheets perpendicular to the planar extent of the foil sheets. The inlet and outlet ports provide access for a first fluid to flow into or out of the internal plate passages formed between the two foil sheets. Interstitial channels are formed between the series of plates and configured to allow the flow of a second fluid between the series of plates, allowing heat to be transferred between the two fluids while isolating the two fluids from one another.

A heat exchanger component comprises a core portion with alternating first and second heat exchanging channels. A first ducting portion comprises first ducting channels for transfer a first fluid between a first fluid inlet/outlet and the first heat exchanging channels of the core portion, and second ducting channels for transfer of second fluid between a second fluid inlet/outlet and the second heat exchanging channels of the core portion. The first ducting channels direct the first fluid around the turn of at least 45 degrees and the second ducting channels direct the second fluid around a turn of at least 90 degrees. The first and second ducting channels are interleaved.

The extending direction of a fifth rib that is one of a plurality of first ribs of a first header portion is closer to the extending direction of flow paths in a first counter-flow portion than the extending direction of a sixth rib that is a rib of the plurality of first ribs closer to a fourth edge than the fifth rib. The extending direction of a seventh rib that is one of a plurality of second ribs of a second header portion is closer to the extending direction of the flow paths in the first counter-flow portion than the extending direction of an eighth rib that is a rib of the plurality of second ribs closer to a sixth edge than the seventh rib.
