  • Patent number: 10458723
    Abstract: The present invention is a cross-flow evaporator adapted to generate vapor from the heat of the exhaust gases from an internal combustion engine. The evaporator is constituted, among other elements, by two plates spaced from one another which contain chambers. The heat exchange tubes alternately communicate the chambers of both plates, establishing a specific path for the fluid intended to change phase. The tubes extending between the chambers of the two plates are arranged transverse to the flow of the hot gas. This evaporator is suitable for heat recovery systems using a Rankine cycle, making use of the heat from the exhaust gases. The invention is characterized by a special configuration of the chambers by means of caps that allow the evacuation-of the gases generated during a brazing welding in the manufacturing process.

  • Patent number: 9313829
    Abstract: Aspects of this disclosure enhance elimination problems that freezing sulfur creates with gas-liquid parallel plate separators by integrally heating the parallel plate gas-liquid separator assembly. Through integral heating the duration of time that the separator apparatus remains above the freezing temperature of elemental sulfur is prolonged, thereby, allowing the opportunity for residual liquid sulfur to drain from the parallel plate assembly during upsets in unit operations and after a sulfur recovery unit shutdown event, thereby reducing or eliminating the operation and maintenance problems that may occur with existing separator designs.

    Abstract: Heating, ventilation, air conditioning, and refrigeration (HVAC&R) systems and heat exchangers are provided that include multichannel tube configurations designed to reduce refrigerant pressure drop through a heat exchanger manifold. In certain embodiments, tubes inserted within the manifold adjacent to a refrigerant inlet have non-rectangular or recessed end profiles configured to increase flow area near the inlet, thereby reducing a pressure drop through the manifold. In further embodiments, insertion depths of the tubes within the manifold vary based on distance from the inlet. This configuration may establish a larger flow area adjacent to the inlet, thus reducing the pressure drop and increasing heat exchanger efficiency.
