Disclosed is a method for producing a plate-shaped heat exchanger for batteries or converters for generating electricity, to a plate-shaped heat exchanger for batteries or converters for generating electricity, and to an assembly of plate-shaped heat exchangers and converter or battery cells. A plate-shaped heat exchanger includes two frame parts, which peripherally surround one profiled heat-conducting element each, wherein the profiles of the profiled heat-conducting elements form channels in the connected state of the frame parts, through which channels a fluid can be conducted. In the connected state, the frame parts form at least two supply channels for feeding and leading away of fluid, from which supply channels openings extend to the channels of the profiled heat-conducting elements. The frame parts have at least one connection for the feeding and leading away of fluid for each supply channel, which connection can be connected to a connection of a frame part of a further heat exchanger.

An EGR cooler includes a heat exchanging core which has a plurality of tubes, an upstream-side gas tank portion upstream of the tubes and a downstream-side gas tank portion downstream of the tubes. A water tank portion forms a first water passage around the tubes and forms a second water passage around the upstream-side gas tank portion. A double pipe portion forms a gas passage which communicates with the upstream-side gas tank portion and forms an annular water passage which communicates with the second water passage. A water inflow pipe is connected to the double pipe portion such that the cooling water flows into the annular water passage, and a water outflow pipe that is connected to the water tank portion such that the cooling water flows out from the first water passage.

An indirect gas cooler is constructed from stacked pairs of plates with fins arranged in between. The stack is arranged in a housing into which the gas flows, flows through the fins, and leaves the housing again. The gas is in thermal exchange with the liquid that flows in the plate pairs and that is introduced into the plate pairs via at least one inlet and is discharged via at least one outlet. A ventilating member is provided in the stack for discharging entrained gases from the liquid. The ventilating member is formed from aligned plate openings which produce a ventilating duct that is hydraulically connected with a liquid space in the stack. The indirect gas cooler can be used to cool compressed charge air for an internal combustion engine.

In order to improve sealing performance when the open end of a tank is swaged and thereby secured inside an annular groove the surface of which is formed in a substantially rectangular shape with a seal material between the groove an the tank, flange parts protrude in a fan shape at the four corners of the seal material, and those flange parts are pressed by the corner sections of the annular groove, thereby preventing the seal material from moving in the corner sections.

The invention relates to an assembly of two parts crimped together by folding at least one portion of peripheral edge (12) of one so-called first part (8) over the other so-called second part (9). Said first part (8) has a hinge-forming region facilitating the folding of said portion of peripheral edge (12). The invention also relates to a manifold comprising said assembly and a heat exchanger comprising said manifold.
摘要:
A method of exchanging heat between fluids with a heat Exchanger comprising a three-dimensional ordered microstructure material within a shell. The three-dimensional ordered microstructure material has dimensions that allow for large surface area to volume ratios, between 300 and 15000 m2/m3. Alternatively the three-dimensional ordered microstructure may have an open volume fraction between 0.4 and 0.6. The three-dimensional ordered microstructure may be comprised of hollow truss elements and partially filled with a thermally conductive material or a fluid. The Heat Exchanger has a heat transfer coefficient multiplied by the surface area to volume ratio between 3.7*107 and 7*109 Watts per M3K.
摘要:
A heat exchanger for indirect heat exchange between a first fluid and a second fluid, with a shell surrounding a shell space for receiving the first fluid, a tube bundle having a plurality of tubes arranged in the shell space for receiving the second fluid, the tubes arranged in a number of tube layers, and a jacket arranged in the shell space and enclosing an outermost tube layer in the radial direction of the tube bundle. An intermediate space is formed between the tube bundle and the jacket surrounds the tube bundle. At least one elastic element is arranged with a first region between neighboring tube portions in the outermost tube layer and a second region that protrudes out of the outermost tube layer and abuts an inner side of the jacket that is facing the tube bundle or connects the elastic element to the jacket.

A cold and/or heat accumulator has a first heat exchanger and preferably a second heat exchanger. The first heat exchanger may, in particular, be provided to be perfused by a refrigerant while the second heat exchanger is preferably perfused by brine. The first heat exchanger and preferably also the second heat exchanger are engaged in a heat-exchanging relationship with carrier elements charged with a cold or heat storage medium and may, in particular, be formed by graphite strips.
摘要:
A heat exchanger that is constructed with a heat exchanger shell having inlet and outlet plenums and fluid inlet and outlet ports, and a tube sheet construction disposed in the heat exchanger shell. The tube sheet construction includes at least two separate tube sheets and a plurality of tubes that extend between the separate tube sheets. Each tube sheet includes at least two planar tube sheet segments and an interstitial layer disposed between the at least two tube sheet segments, and at least one sensor element supported by each of the interstitial layers. A control monitor controls flow through the shell by a feedback control from the sensor to an inlet control valve and/or a stimulus device excites the media layer.
