Definitions

  • This invention concerns a block manifold for fitting to heat exchanger batteries and especially for fan coils.
  • the heat exchanger batteries have fluid circulation pipes the ends of which are connected to manifolds through which the fluid flow and return pipes are connected.
  • manifolds have a block body with a part fitting to fluid piping, two, three or more branches for connection to the battery pipes and a distribution chamber between the fitting and the said branches.
  • this cylinder is cylindrical and its geometric axis is oriented transversally to the axes of the fitting and the branches which are substantially parallel to each other.
  • this chamber By its presence and conformation, this chamber is already a cause of turbulence in the fluid and a loss of pressure in the system and contributes to pointlessly increasing the external dimensions of the manifold.
  • this intermediate cylindrical chamber is left open at one end and is only closed, with a plug, generally welded on, at the end of machining. This plug represents a critical part of the manifold.
  • Block manifolds are known in the state of the art, as shown by documents EP-A-0758734, US 4,948,177, US 1,092,385, US 1,160,839, US 1,205,508, US 2,673,101, US 5,176,177, US 3,951,440, US 5,078,432, US 5,143,151, US 5,908,288, GB 10174, GB 897965, US 3,790,966, US 4,013,049, US 4,541,448, US 6,202,686 and US 6,237,408.
  • the purpose of this invention is to create and supply a manifold for heat exchanger batteries which is new and original in conformation, capable of providing diverse advantages over manifolds of known technical merit in construction, economical and functional terms.
  • a manifold for the use cited above which includes a block body: here, the distribution chamber, located between the fitting and branch parts is coaxial to the fitting and on a parallel axis to the said branches.
  • all the parts of the manifold are oriented in parallel to each other in the same direction.
  • This allows a reduction in the external dimensions of the body, while maintaining the technical characteristics required for its use and a reduction in the raw materials used to make it.
  • the internal machining of the body to provide communication between the fitting and the branches can be performed by passing axially from the fitting without the need for lateral openings. The insertion and welding of a plug is thus eliminated and consequently also the risk of rejects and some production costs.
  • the intermediate chamber with its axis parallel to the fitting and the branches contributes to reducing if not completely eliminating, the turbulence in the fluid and the pressure losses in the supplied system.
  • FIG. 1 shows a perspective view
  • - figure 2 shows a side view
  • FIG. 5 shows a section according to the V-V arrows in Fig. 3.
  • FIG. 6 shows a cross-section of a part of the body according to the VI-VI arrows in Fig. 3.
  • the manifold is comprised of a block body, usually made of brass.
  • the resulting body is obtained with normal forming techniques and then machined for the finish required.
  • This body when finished, has a fitting 12 with an internal thread on one end and two, three or more branches on the opposite end 13; inside there is a distribution chamber 14 which connects the fitting 12 and the branches 13.
  • a distribution chamber is a chamber in which the fluid passing through can be distributed between any branch of said branches 13.
  • a distribution chamber is a chamber in which the fluid passing through can be shared with the branches.
  • the fitting 12 has a geometric axis X; the branches 13 are in parallel Y axes to the X axis of the union part.
  • this is circular and completely closed all round, coaxial with the fitting and with a radius broad enough to intersect the branches. All this to achieve the purpose and advantages described above.
