Definitions

  • the present invention relates to an improved thermal efficiency radiator for bath rooms and the like.
  • Bath room radiators comprising a pair of upright manifolds therebetween a plurality of horizontal pipes extend, said pipes being arranged in several pipe beams.
  • the horizontal pipes are provided, at end portions thereof, with a rectilinear cut, that is a cut extending orthogonally to the pipe axis.
  • these pipes are coupled with their ends flush with the uprights, by means of welding or other like operations.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing an improved thermal efficiency radiator for bath rooms and the like, which is adapted to provide an optimum thermal exchange, mainly at the top portion of the radiator, thereby also providing an increased thermal efficiency.
  • a main object of the present invention is to provide such a radiator which is very simple construction-wise and can be series produced by conventional apparatus and systems.
  • Yet another object of the present invention is to provide such an improved thermal efficiency radiator which is very safe and reliable in operation.
  • Yet another object of the present invention is to provide such a radiator which can be quickly and easily constructed starting from easily available material and elements and which, moreover, is very competitive from a mere economic standpoint.
  • an improved thermal efficiency radiator for bath rooms and the like characterized in that said radiator comprises a pair of upright manifolds coupled to one another by a plurality of horizontal pipes having, at the coupling end portions thereof, respective slanted cuts, said cuts being slanted with a given angle with respect to the pipe axis, at least a portion of the pipes having the longer end thereof downward turned, and at least a further portion of said pipes having the longer ends thereof upward turned.
  • the improved thermal radiator for bath rooms and the like, according to the invention, and which has been overally indicated at the reference number 1, comprises a pair of upright manifolds 2 which, advantageously, have a substantially circular shape and are provided with bottom and top lead-in portions 3 and 4 as well as with a side lead-in portion 5.
  • these lead-in portions are made of threaded ring nuts, provided for coupling with closure plugs or fitting elements for the heating sources.
  • the uprights 2 are coupled to one another by means of a plurality of horizontal pipes, overally indicated at the reference number 10, which have the main feature of being provided, at the ends thereof which are coupled to the upright manifolds 2, with a cut slanted with respect to the pipe axis.
  • the ends of the horizontal pipes 10 are made with a cut slanted at about 10° with respect to the pipe axis, so that each end portion will be provided with a longer part and a smaller part.
  • the radiators 1 can be made starting from a plurality of pipe beams, that is a plurality of horizontal pipes 10; in the embodiment shown in figure 1, there is provided a radiator having two pipe beams; here, the pipes of the bottom pipe beam, indicated at 20, have the longer ends thereof upward turned.
  • the bottom pipe beam 20, as well as the top pipe beam 21 will have the above disclosed arrangement, whereas the middle pipe beam, indicated at 22, will have its longer end turned toward the main faces, that is turned through 90° with respect to the end portions of the bottom and top pipe beams.
  • the fourth pipe beam arranged at the top end of the radiator, will have the longer end thereof upward facing.
  • the slanted cut ends of the horizontal pipes 10 are engaged, for a given length, within the upright manifolds 2 and, preferably, these pipes are introduced in the manifolds for a length of 5-10 mm.
  • the main operating portion of the radiators that is the bottom portion thereof, will be subjected to a turbulent thermal exchange primary fluid, provided, in the arrangement being disclosed, by the larger length ends of the horizontal pipes, which will practically increase the flow rate of the thermal exchage primary fluid in the upward direction.
  • Another main aspect of the present invention is that the above disclosed arrangement affords the possibility of making the radiators in a large series without any increase of the production cost, and provided, a very safe and reliable product.
  • the used materials, as well as the contingent sizes and shapes can be any, according to requirements.
