  • Yet another aspect of the modular heat diffuser is to provide a homogeneous heat diffusion when it is part of a dry heat radiator and thus obtain a homogeneous temperature in the surroundings of the radiator.
  • Yet another aspect of the modular heat diffuser is to increase the heat transmission to the environment by modifying the geometry of some fins that shape the modular heat diffuser, while decreasing the heat transmission to the suspended dust particles. in the environment, without it being necessary to increase the power of a unit or electro-resistant units generating heat energy included in the dry heat radiator.
  • the increase in heat transfer capacity of the heat diffuser is achieved by modifying the front, rear and fins external willing on both sides of the central fin it achieves, so that instead of adopting a flat shape, in this case they give shape to undulating, broken and / or mixed surfaces, which provides a considerable increase in the radiating surface of the heat diffuser.
  • the modular heat diffuser comprises a front flap, a rear flap arranged in parallel and joined by a central connecting flap arranged perpendicularly to the previous ones in a type H-shaped section; where the modular heat diffuser further comprises external fins perpendicular to both sides of the central joint flap, adopting a broken section shape comprising a set of discontinuous, broken and rectilinear discontinuous external fin segments arranged consecutively and the outer fin segments are arranged each of the pampering at a predetermined distance from both front and rear fins.

  • FIG. 1 illustrates a modular heat diffuser 11 which by convection and radiation heats the air surrounding it.
  • the heat diffuser 1 1 comprises a front flap 12 and a rear flap 13 arranged in parallel and joined by a central joint flap 17 arranged ⁇ ⁇ ⁇ to the above in a form of section type H,
  • the heat diffuser 1 1 comprises external fins 15 arranged perpendicularly to both sides of the central fin 17.
  • the external fin 15 adopts a broken sectional shape comprising a set of discontinuous, broken and rectilinear discontinuous external fin segments arranged each outer fin segment 15 at a predetermined distance from both front and rear fins 12.
  • a set of heat diffusers 1 1 are assembled to form a modular electric radiator 21, of the type of so-called dry heat, that is, it does not contain oil or other thermal fluid.
  • Said radiator has one or more housings for the location of a heat generating unit 14 of the electrical resistance type.
  • the dry heat radiator 21 is generally attached to a wall of a room by means of mechanical fastening and anchoring means 16 that hold the heat radiator 21 at a predetermined distance.
  • the front flap 12 adopts a wavy section shape so that the succession of undulations, that is, the continuous succession of valleys and ridges are arranged horizontally and, in addition, the upper edge of the front flap 12 ends in a ascending oblique slope that represents the transition between a valley and a ridge of the undulating surface, so that an air spring, which ascends along the outer surface of the front fin 12 of the heat diffuser 1 1, is directed away of the wall.
  • the rear flap 13 adopts an inverted J-shaped section and has a radiating surface lower than the radiating surface of the front flap in order to reduce heat transfer to the wall. Therefore, the upper end of the rear flap 13 has an ascending oblique section that directs an upward air flow in the direction of wall removal
  • the discontinuous external fin 15 has a mixed configuration that combines rectilinear and wavy segments in the form of an S-type section. The possible options of the external fin 15 in relation to the geometry thereof are a function of the number of electrical resistors 14 included. in the dry heat radiator 21.
  • the heat radiator 21 includes two electrical resistors 14 where a first resistor is disposed in an area near the lower edge of the radiator 21 and a second resistor is disposed in an area near the upper edge of the radiator 21;
  • the geometry of the external allele 15 is such that the air that is heated by the lower resistance is directed towards the upper outlet end of an alley or channel defined primarily by the front 12, rear 13 and central 17 connecting fins, and moving away said hot air source of the upper resistance in order to prevent the latter resistance from reheating said air flow and, in turn, the dust particles it carries are also reheated.
  • the lower and upper resistance are arranged within a ridge of the corrugated surface of the front fin 12 in order to define the geometry of the channel for the passage of the air stream heated by the lower resistance, [ 0033] It can also be seen in Figure 1, that the lower end of the alley is divided into two channel sections by a segment in a J-shaped shape rotated to the right of the outer fin 15 in order to divide the cold air stream that it enters through said lower end, directing a part of the air stream to the lower resistance and another part of the air source to the upper resistance.
  • the external fin 15 keeps the two air currents along the alley of the heat diffuser. Said separation is also maintained at the exit end of the alley by a rectilinear segment of the external fin 15 arranged from the upper resistance and ending in the vicinity of the end of the alley.
  • the external fin 15 comprises an oblique parallelogram 16, the inclination of which is a function of the inclination of the upper end of the front and rear fin 12.
  • the geometry of the set of discontinuous segments of external fin 15 is configured to divide an air stream into two flows and direct both hot air flows, each heated by an electric resistor 14 comprised within the heat diffuser 11, in its upward vertical displacement, due to the phenomenon of convection, moving said hot air streams away from the wall to which the dry heat radiator 21 is attached.
