    摘要: A heat transfer system includes a steam chamber that communicates in an open-loop arrangement with a first steam source for supplying steam to the steam chamber, the steam chamber including a steam exit for supplying steam to air at atmospheric pressure. A heat transfer tube communicates in a closed-loop arrangement with a second steam source for supplying steam to an interior surface of the heat transfer tube, the heat transfer tube vaporizing condensate forming within the heat transfer system back to steam that is supplied to the air via the steam exit. The outer surface of the heat transfer tube is configured to contact the condensate and vaporize the condensate back into steam, wherein the heat transfer tube includes a plurality of pockets formed on the outer surface of the tube, each pocket including a pocket exit/entry portion having a smaller cross-sectional area than the cross-sectional area of the pocket at a root portion thereof adjacent the outer surface of the tube.

    摘要: A heat exchanger and an antenna assembly having the same are described herein that enable a compact antenna design with good thermal management. In one example, a heat exchanger is provided that includes tube-shaped body. A main cooling volume is formed between the top and bottom surfaces proximate to the outside wall. The main cooling volume has an inlet formed through the top surface and an outlet formed through the bottom surface. A return volume is formed adjacent the inside diameter wall and is circumscribed by the main cooling volume. The return volume has an outlet formed through the top surface and an inlet formed through the bottom surface. One or more exterior fins are coupled to an exterior side of the outside wall. A plurality of fins extend into the main cooling volume. A plurality of inner fins extend into a passage from the inside diameter wall.

    摘要: A flat tube for an exhaust gas cooler including two flat wide sides and two rounded narrow sides. The flat tube further including a plurality of moulded turbulence projections arranged on the two wide sides in two flow rows and projecting from a respective one of the two wide sides toward the other of the two wide sides. The plurality of turbulence projections are respectively structured in an elongated manner and arranged at an angle relative to a longitudinal direction. The flat tube also including a plurality of moulded support projections projecting from a respective one of the two wide sides away from the other of the two wide sides. The plurality of support projections are arranged between the two flow rows. The two narrow sides each have an elongated flat region that merges into the two wide sides via a plurality of rounded corner regions.

    摘要: A compact gas-gas heat exchange tube. The heat exchange tube includes a heat transfer tube which is configured to separate an in-tube fluid from an out-tube fluid, and achieve, through convection and heat conduction manners, heat transfer between the in-tube fluid and the out-tube fluid; an inner fin set which is configured to expand a heat exchange surface on an inner side of the heat transfer tube, form a micro-channel to separate the in-tube fluid to make the same to axially flow along the heat transfer tube, and produce a turbulence effect and enhance heat convection as well; an outer fin set which is configured to expand a heat exchange surface on an outer side of the heat transfer tube, form a micro-channel to restrict the out-tube fluid from axially and reversely flowing along the heat transfer tube, and produce a turbulence effect and enhance heat convection as well, wherein a hole is provided on each fin of the inner fin set or/and the outer fin set. The present invention further provides methods for manufacturing and using the compact gas-gas heat exchange tube. The present invention realizes complete reverse flow and efficient heat transfer in a limited space and under a heat exchange working condition of a small logarithmich mean temperature difference, saves a spatial dimension of the apparatus, and reduces a weight of each area as well so as to reduce a total weight and a manufacturing cost.

    摘要: An improved heat exchanger suitable for use as a pre-cooler in an internal combustion engine exhaust gas recirculation system includes an inner heat exchange tube for exchanging heat between a gas and a coolant. A tubular outer body surrounds at least part of the inner heat exchange tube. Coolant flows through a cavity formed between the outer surface of the inner heat exchange tube and the inner surface of the tubular outer body, cooling the gas flowing through the inner heat exchange tube. The inner heat exchange tube surrounds a rolled, cylindrically-shaped corrugated sheet of material forming a plurality of fins. At least one of the fins is in contact with an inner surface of the inner heat exchange tube. The tubular outer body surrounds two or more inner heat exchange tubes, each inner heat exchange tube surrounding a respective plurality of fins.
