  • Publication number: 20110185712
    Abstract: An energy separation and recovery system wherein energy forms which might otherwise be wasted are employed in conjunction with a heat exchanger and a super heater to generate steam in a substantially closed-loop system wherein the heat supply is an open system. The superheated steam is transmitted to an engine to generate power which may be used to supply electrical energy. The electrical energy may be employed external to the system. Stepped diameter tubing carries water, or other vaporizable fluids, through the heat exchanger into the super heater while simultaneously exposing the carried water or fluid to incrementally higher temperature heated gas. Variable bellows, attached operatively to end plates accommodate the differential expansion of the tubing. The energy generation system includes a control module to permit the generation of steam and electricity at such times as there is sufficient heat to permit the generation of superheated steam.

  • Publication number: 20110127022
    Abstract: A heat exchanger for exchanging heat between a first fluid and a second fluid is disclosed; wherein the heat exchanger has improved thermal efficiency and low fluid back pressure. The heat exchanger comprises conduits for conveying the first fluid, wherein the conduits include a plurality of flow passages. The flow passages are defined by a plurality of fins that are continuous along the direction of flow of the first fluid. Each fin includes a wave-shaped region, and adjacent fins sub-divide each flow passage into first and second sections that are interposed by a third section. The wave-shape of the fins creates a continuously varying cross-sectional area for each third section. The variation of the cross-sectional area of the third section, coupled with the wave-shape of the fins, induces a swirl flow between the third section and each of the first and second sections. This swirl flow improves the efficiency of the overall convection heat transfer in each conduit.

    Abstract: A secondary refrigerant fluid is cooled or heated in the operation of a multiple Tube-fins heat exchanger arranged in parallel for fins to conduct heat transfer with air being propelled by a multi-row bank of low profile brushless fans. Fluid is controlled to ascend the bank of tubes in unison rate for high efficiency heat transfer with air. Large temperature differential exists between air and fluid when conditioned fluid travels through the tubes for a relatively short distance. A system of components is so arranged that the fluid flow rate to every heat exchanger is preset and the “on” or “off” operation of any heat exchanger does not affect the flow rate destined for other heat exchangers. Fluid is not transported to a heat exchanger when it is not in operation saving energy. Each heat exchanger is controlled by an integrated thermostat so occupants can set the air conditioning operation individually independent of all other heat exchangers.

    Abstract: The present invention discloses a fin for a heat exchanger, the fin is formed with louvers, and air, which is used as heat exchange medium, successively flows through said louvers when the heat exchanger operates. The louver gap of the louvers changes in the air flow direction, such that a louver gap at a certain portion of the louvers matches with an amount of frost formed at that portion. With the technical solution of the invention, the louver gap at a certain portion of the louvers is made to match with the amount of frost formed at that portion, such that a sufficient space is still left between adjacent louvers for the air to flow through. As a result, the wind resistance will not increase substantially to decrease the amount of air flowing through, and thus the heat exchange performance of the fin can be utilized completely.

    Abstract: A heat exchanger includes a first generally vertical header and a second generally vertical header and a generally vertical array of a plurality of generally flat heat exchange tubes extending in a horizontal direction therebetween. Each heat exchange tube has a plurality of channels extending longitudinally in parallel relationship from its inlet end to its outlet end, each channel defining a discrete refrigerant flow path. A plurality of fins extends between parallel-arrayed tubes. To facilitate drainage of the collected condensate from the external surfaces of the flat heat exchange tubes, the tubes are aligned at a slight angle with respect to the horizontal so that the trailing edge of each tube is positioned lower than the leading edge of each tube. To further assist in the condensate drainage, the trailing edge of each of the fins may extend beyond the trailing edge of the associated heat transfer tubes and a lower extension lip may extend downwardly from the trailing edge of each of the fins.
