Definitions

  • the subject of the invention is an air-cooled heat exchanger applicable, in particular, to heating and ventilation systems, air conditioning, cooling, cooling or heating fluids, condensation or evaporation of gases.
  • the subject of the invention is a cylindrical heat exchanger with fan - forced draft, including a set of tubes forming a media distribution system, equipped with finned disks for heat transfer.
  • an air-water mechanical draft cooling tower which has a cylindrical housing inside which there is a cylindrical filler.
  • the filler is made out of a sheet metal strip shaped like an Archimedean spiral and rolled around a tube positioned concentrically to the housing.
  • the core ends with a conical extension, well below the deposit.
  • the cylindrical housing has a series of holes on its circumference. They are located at the same level below the filler and serve to transfer cold air to the filler.
  • Over the filler there are sets of spray heads positioned at an angle to its upper surface. The heads are attached to the cover around the circumference and to the hot water tank located just under the cover.
  • Air-water mechanical draft cooling tower described for the Polish Patent No 206 746 has spray heads arranged symmetrically above the filler on at least two rings, an external and internal one.
  • the outer ring is connected with a water supply tube and with at least three other tubes linking the outer ring.
  • Over the rings there is a drop separator mounted in the cylindrical housing. Its both bases are made of a perforated material, preferably mesh.
  • a filler consisting of short tube segments arranged loosely. The lower surface of the filler is perpendicular and positioned at a preferable right angle to the vertical axis of the filler.
  • the heat exchanger consists of a bundle of straight sheets cut in the shape of a circle and separated by seals with which they form closed spaces with intake and outlet holes.
  • a bundle of sheets and seals forms a multi-channel sector through which each heat exchanging factor flows in turns. The whole segment is nestled between two thick plates-screws.
  • Patent Application Publication US20160290730A1 discloses a tubular heat exchanger with at least two longitudinally extending shell sections each containing a series of fins to which the tube elements adhere.
  • the fan provides airflow across the sections, thus intensifies the heat exchange.
  • the aim of the invention is the construction of the heat exchanger allowing for improving and intensifying heat exchange and at the same time taking up less space.
  • This invention may be used as a cooler or heater of fluids, a condenser or an evaporator of gases, for example refrigerants.
  • the point of the invention is that it contains a number of annular fins in the form of disks arranged one above the other and provided with holes with basically the same turn ups. They serve as spacers of annular fins.
  • Vertical tubes extending over the bottom and upper fins go through the holes. Near the fins there are protruding ends that are grouped in pairs with the aid of U-shaped tubes with the exception of at least one pair acting as an inlet and outlet for fluid flow.
  • On one side of the roller formed by annular fins there is an axial or radial fan mounted whereas on the opposite side there is a conical diffuser allowing for an equal air flow between successive annular fins.
  • the diffuser is of the shape of a truncated cone and on its upper base a compressor is mounted.
  • annular fins are in the form of a continuous strip coiled into a spiral.
  • FIG. 1 shows the heat exchanger in a perspective view
  • fig. 2 shows the heat exchanger in a schematic longitudinal section
  • fig. 3 shows a variant of the heat exchanger
  • fig. 4 shows a cross section of the variant of the exchanger in fig. 3
  • fig. 5 shows a piece of annular fins
  • fig. 6 shows a simplified schematic cross section of the exchanger with a conical diffuser.
  • the heat exchanger contains a number of annular fins 1 arranged one above the other with holes 2 having basically the same turn ups 3 which constitute the spacers of annular fins 1 vertical tubes go through the holes 4 over the lower and upper annular fins 1 and nearby protruding tube ends 4 are grouped in pairs with the aid of U-shaped tubes 5 with the exception of one pair acting as an inlet and outlet for fluid flow.
  • an axial fan installed 6
  • a conical diffuser installed 7 allowing for an equal air flow between successive annular fins 1 .
  • a diffuser 7 has the shape of a truncated cone and a mounted compressor 8 .
  • the example presented in fig. 1 and fig. 4 annular fins 1 are in the form of a continuous strips coined into a spiral.
