A steam generator includes a lower integrated tubesheet and plenum (ITP) configured to receive feedwater and a first set of heat transfer tubes fluidly coupled to a plurality of stubs protruding from a first side of the lower ITP. A second set of heat transfer tubes fluidly couples to plurality of stubs protruding from a second side of the lower ITP. The first set of heat transfer tubes is coiled in a substantially clock-wise direction, and the second set of heat transfer tubes is coiled in a substantially counter-clockwise direction. The steam generator further includes an upper ITP fluidly coupled to the first and second set of heat transfer tubes, wherein the feedwater entering the lower ITP is converted to steam in the first and second sets of heat transfer tubes. The upper ITP is configured to transport the steam away from the steam generator.

An attachment between a heat exchanger and a cell panel of a furnace includes a cell panel including a plurality of cell panel openings and a heat exchanger having a plurality of cells. Each cell has a cell outlet insertable into a cell panel opening of the plurality of cell panel openings. A compressible gasket is insertable between the cell panel openings and the cell outlets and securable therein when the heat exchanger is secured to the cell panel. A crimping tool for securing a heat exchanger cell outlet to a cell panel of a furnace includes a male portion including a split die having two die halves and a die expander configured to separate the two die halves to engage an inner surface of the cell outlet. A female portion applies a force to the cell outlet to crimp the cell outlet to the cell panel.
摘要:
In a heat exchanger, a liquid resin is applied to an outer surface of the heat exchanger, and then surplus liquid resin is removed from the outer surface. In removing the surplus liquid resin, before air having a first velocity is directed to the heat exchanger for blowing the surplus liquid resin off the heat exchanger, air having a second velocity lower than the first velocity is directed to the heat exchanger to remove the surplus liquid resin from the heat exchanger by moving the surplus liquid resin along the outer surface of the heat exchanger. The air at the second velocity is directed toward the heat exchanger by a second blower before the air at the first velocity is directed toward the heat exchanger by a first blower.
摘要:
A heat exchanger is described and illustrated, and in some embodiments includes a casing, a fluid flow path extending between first and second ends of the casing; first and second bundles of heat exchanger tubes in first and second portions of a fluid flow path extending through the casing, and a third section of the fluid flow path connecting the first and second sections and having a sealing plate with one or more apertures for the fluid flow path to pass therethrough. In some embodiments, by virtue of the sealing plate and its relationship with the adjacent structure of the heat exchanger, adjacent ends of the two bundles of tubes are each movable in at least one direction with respect to the casing and the other bundle of tubes.

A parabolic trough solar collector system has a parabolic reflector used with an independently supported collector tube. The parabolic reflector has a reflective surface formed on a reflective surface support structure, supported by a circular support beam. This assembly rests on a plurality of support and drive rollers supported by a roller support arm, supported by a roller support column. The parabolic reflector assembly rotates against the rollers along a single axis to maintain a focus line of the parabolic reflector surface at the same location as the center of the circle described by the outer edge of the circular support beam. Located at this same focus line is the independently supported collector tube not attached to the parabolic trough reflector. The collector tube is supported on pipe roller hangers, which in turn are supported by a wire catenary system connected to support towers which straddle the parabolic reflector.

The present invention provides an illuminating device and heat-dissipating structure thereof. The heat-dissipating structure includes at least one thermally conductive element and a plurality of heat-dissipating units stacked together. Each heat-dissipating unit includes a cone-like fin with an opening and a plurality of protrusions connected to the cone-like fin, wherein at least one of the protrusions of one heat-dissipating unit is coupled to that of the adjacent heat-dissipating unit to form one or more zonal planes for allowing one end of the thermally conductive element to be disposed thereon, and the other end of the thermally conductive element is connected with a heat source to constitute the illuminating device.

A heat pipe and a method for forming the same are provided. The method includes: defining a closed end, a closed portion, and a contact section in sequence along a heat pipe to be processed; closing the opening of the closed end and the passage of the closed portion so as to finalize the heat pipe; and cutting axially the contact section into a plurality of equal parts, bending the equal parts outward to assume a divergent shape, thereby providing the contact section with an area for contact with a heat-generating source. Heat is directly transferred from the heat-generating source to the heat pipe via the contact section, thereby enhancing heat dissipation.
摘要:
In a method of manufacturing heat radiating fin, the technique of plastic working, such as stamping, is employed to apply an external force against a sheet metal material serving as a raw material for forming the heat radiating fin, so that the sheet metal material generates plastic deformation to form a plurality of recessed portions on a front side thereof. Meanwhile, a plurality of protruded portions is correspondingly formed on a rear side of the sheet metal material behind the recessed portions. Any two heat radiating fins so manufactured may be easily stacked and connected together with the protruded portions on a rear or higher heat radiating fin partially extended into the recessed portions on a front or lower heat radiating fin.
