20090044933 | Heat exchanger - A heat exchanger is provided in which heat exchanger shells are formed by electro forming about a mandrel. The shells are attached and joined to provide a heat exchanger module. As the shells are not press formed problems with respect to material elongation to achieve deep grooves in the shells are potentially avoided and shells can be created with more desirable thickness to achieve more efficient heat exchange. Furthermore, reduced shell thickness will also reduce weight and therefore improve the acceptability of heat exchangers in particular applications such as those associated with aerospace and automotive sports. | 02-19-2009 |

20090095454 | Drainpipe heat exchanger - The present invention is a jacket-type heat exchanger which may, for example, be used to replace or fit over a section of drainpipe to heat fresh cold water using the waste heat in the drainwater. Normal cold water pressure is used to create an internal-expanding force on the inner thermal contact wall of the jacket, which, in turn, creates an enormous heat-transfer clamping force on the drainpipe for fast heat transfer. A longitudinal gap in the jacket (or a two-piece jacket) enables clamping movement. An external sleeve with clamps resists bulging of the outer jacket wall. The heated cold water is plumbed to a faucet or water heater so as to reduce hot water use, which, in turn, reduces energy use and related environmental damage. Double-wall construction and venting for visible leak detection satisfies plumbing code requirements. A horizontal embodiment discloses a two-piece plastic-copper drainwater heat exchanger. Use on vehicular exhaust pipes is also contemplated for providing instant interior heat and/or motor warm-up. | 04-16-2009 |
20090101321 | Heat Exchanger - The invention presents a MONOBLOC fin and plate heat exchanger design preventing internal leakages and intermixing of high-temperature and low-temperature flows, e.g. oil and fuel. This is achieved through a particular configuration of the heat exchanger, whereby its core assembly is completely or partially produced from a one-piece monolithic metallic block. Owing to that, all brazed seams, which in conventional fin and plate heat exchangers contact with both hot medium and cold medium flows, are fully abolished thereby excluding a source for imperfections usually developing in brazed joints and base metal in the process of pressure-temperature cyclic loading. Employing custom-made individual fins allows about two-fold increase in the strength of brazed joints in comparison with ordinary corrugated fins (due to doubling of the brazed surface). As a result, the suggested configuration allows the design of a high reliability compact heat transfer device for much higher operating pressures than what may be achieved in the conventional fin and plate heat exchanger. This invention may be used in different fields of modern technology, especially for aeronautical engine applications, where the challenge of ensuring reliability levels of one failure in millions of (fleet-cumulative) flight hours, and operating pressure levels of thousands of pounds per square inch, must be met. | 04-23-2009 |

20160003549 | COOLING PROMOTING STRUCTURE - A cooling promoting structure in which a first flow path walls includes a first collision surface which collides with cooling gas flowing through a first flow path, a second flow path walls includes a second collision surface which collides with the cooling gas flowing through a second flow path, and the first flow path and the second flow path are connected to each other via inflow openings at a location where the first collision surface and the second collision surface are disposed. | 01-07-2016 |
20160003552 | COUNTERCURRENT HEAT EXCHANGER/REACTOR - Counter-flow heat exchanger is constructed with plenums at either end that separate the opposing fluids, the channels of which are arrayed in a checkerboard patterns, such that any given channel is surrounded by channels of opposing streams on four sides—laterally on both sides and vertically above and below. | 01-07-2016 |
20160054071 | HIGH EFFECTIVENESS LOW PRESSURE DROP HEAT EXCHANGER - A heat exchanger in the form of a honeycomb with a plurality of rectangular or otherwise polygon in cross-section passages which share common walls with adjacent passages. Two or more flow paths each comprises a plurality of serially connected passages. Each flow path passes through the heat exchanger in a helical pathway, thus through one passage in a first vertical stack of passages, then through a lower passage in an adjacent second vertical stack of passages, then through a lower passage in the first vertical stack, then through a lower passage in the second vertical stack and in this helical manner to the outlet from the heat exchanger. Thus, the flow path comprises alternate passages in each vertical stack, and another flow path comprises the alternate passages in at least one of the vertical stacks not taken up by the first flow path, whereby the flow paths at least partially overlap each other thereby providing both counter-flow and co-flow. | 02-25-2016 |
20160076816 | MANIFOLD FOR PROCESS VARIABLE TRANSMITTER WITH STEAM COUPLING - A process variable transmitter manifold is provided that includes a valve body having a valve and a flanged mounting face. The valve body has a port therethrough for selectively coupling a process fluid through the valve, and a cooling channel in the valve body. The cooling channel has an inlet, an outlet, and a passage connecting the inlet and the outlet. A method of controlling temperature of a process fluid in a manifold is also provided. The method includes passing fluid through a channel in the manifold, passing the process fluid through at least one bore through the manifold, and adjusting temperature of the process fluid through conductive cooling or heating of the process fluid based on the certain temperature of the fluid passing through the channel. | 03-17-2016 |
20160107274 | METHOD FOR PRODUCING A HEAT EXCHANGER MODULE HAVING AT LEAST TWO FLUID FLOW CIRCUITS - A method for producing heat exchangers having at least two fluid circuits each having channels, including the following steps: producing one or a plurality of elements of a first fluid circuit, each element having at least two metal plates, at least one of which has first grooves; stacking the at least two metal plates of each element in such a way that the first grooves form the channels of the first circuit; assembling each element of the first circuit by diffusion welding between the two stacked metal plates; producing one or a plurality of elements of at least one second fluid circuit, each element of the second circuit having at least a portion of the channels of the second circuit; assembling, either by diffusion welding, or by brazing, or by diffusion brazing between the element or elements of the first circuit and the element or elements of the second circuit. | 04-21-2016 |
20160131443 | HEAT EXCHANGER - A heat exchanger transfers heat between first and second material streams. The heat exchanger includes a body portion including vent channels configured to pass the first material stream through the body portion. The body portion further includes feed channels configured to pass the second material stream through the body portion. The feed channels are spaced from and in thermal communication with the vent channels such that at least one of the first and second material streams transfer heat with another one of the first and second material streams. Each of the feed channels has an inlet having a crosssectional area with the cross-sectional area of the inlet of at least one of the feed channels different than the cross-sectional area of the inlet of another one of the feed channels for normalizing a flow rate of the second material stream through the feed channels. | 05-12-2016 |
