Definitions

  • This invention relates to a radiant module for the formation of a radiant body.
  • a radiant body is a known apparatus which, positioned inside a confined space or inside room, is designed to increase or maintain a predetermined temperature in the room.
  • the radiant bodies comprise, usually, a plurality of modules side by side (the number depending on the total size of the radiant body and the desired operating capacity) and connected to each other in a sealed fashion.
  • a heat carrier fluid heated to a predetermined temperature by a thermal energy source, such as, for example, a boiler, flows inside the modules of the radiant body.
  • the radiant body therefore forms part of a water circuit in which the heat carrier fluid circulates.
  • the current hydraulic circuits comprise a thermal energy source, such as, for example a boiler, which heats the heat carrier fluid, which is then made to circulate in the radiant body.
  • a thermal energy source such as, for example a boiler
  • the heat carrier fluid is water and the circulation of the heat carrier fluid is actuated thanks to the use of a pump.
  • the modules can be connected permanently, by welding, or coupled to each other during assembly through a connection element and a plurality of seals.
  • the connecting elements are tubular conduits which also act as conduits for supplying and discharging the heat carrier fluid.
  • the first constraint relates to the shape of the modules of the radiant body: This restraint derives from the fact that the exchange surface between the heat carrier fluid and air is not determined according to predetermined directions, but occurs freely depending on the current flows of the air present in the room.
  • the second constraint concerns the structure of the modules of the radiant body. This constraint derives from the fact that, even though the use of material with a high coefficient of heat exchange would improve the performance of the radiant body, the latter, in to obtain a high thermal efficiency, could reach temperatures which are too high, with high operating costs and possible wear of the radiant body in a short time.
  • the aim of this invention is to provide a module for a radiant body which overcomes the above-mentioned drawbacks.
  • a further aim of this invention is to provide a module for the formation of a radiant body which can increase the performance in terms of heat exchange.
  • Another aim of this invention is to provide a module for the formation of a radiant body which is able to modify and improve the external design independently of the thermal efficiency and the heat exchange surface area.
  • Another aim of this invention is to provide a module for the formation of a radiant body wherein the choice of the materials of the module is independent of the safety problems of the rooms in which it is applied.
  • the reference numeral 1 denotes in its entirety a radiant module according to the invention and which can be used for the formation of a radiant body 5 designed to increase or maintain a predetermined temperature in the room in which it is positioned.
  • the radiant module 1 comprises a first hollow body 3.
  • the first hollow body 3 is defined by a front wall 301, a rear wall 302, two sides 303, a top end 304 having a pair of holes 308 made on the corresponding sides 303 and a bottom end 305 having a pair of holes 308 made on the corresponding sides 303.

  • the radiant module 1 comprises a second hollow body 2 or cover casing inside of which is entirely contained the first hollow body 3.
  • the second hollow body 2 has a front wall 201, a rear wall 202, two sides 203, a top 204, having an air discharge section B and a pair of holes 4 made on the corresponding sides 203 and a bottom 210 having an air intake section A and a pair of holes 4 made on the corresponding sides 203.
  • the second hollow body 2 is configured for generating an inner zone which is able to define a channel C2 for controlled flow of the air from the intake section A of the bottom towards the discharge section B of the top 204.
  • each module 1 has a first hollow body 3 with the function of a radiant element (the heat carrier fluid passes through this element), whilst the second hollow body 2 acts as a convertor of air from the bottom upwards (as described in more detail below) with a "flue" effect so that the low temperature air flows from the bottom and the heated air flows from the top.
  • the radiant module 1 allows three axes of extension to be identified:
  • an embodiment of the first hollow body 3 comprises a upper chamfer 306 which connects the front wall 301 to the top end 304 and a lower chamfer 306' which connects the front wall 301 to the bottom end 305.

  • the first hollow body 3 also has two other passage holes 308, which are made on its opposite sides 303 in the lower part, defining the second bottom end 305, and in such a way as to be opposite and coaxial with each other (see also Figures 4A and 4B ).
  • passage holes 308 are configured for being coupled with the supply conduit 501 and with a discharge conduit 502 of the heat carrier fluid.
  • the first hollow body 3 comprises, at the passage holes 308, a corresponding seat for housing the seals (not illustrated) of the two supply 501 and discharge 502 conduits.
  • the first hollow body 3 has a substantially parallelepiped shape.
  • the first hollow body 3 has a substantially tubular shape folded back on itself in such a way as to form a coil which increases the heat exchange surface (not illustrated).

  • the second hollow body 2 comprises a front wall 201, a rear wall 202, two sides 203, a top 204 and a bottom 210.
  • the bottom 210 of the second hollow body 2 has an inlet section A which is larger than the discharge section B of the top 204 for drawing in the air from the room and forcing it to flow into the flow canal of C2 identified by the respective walls of the first 3 and second 2 hollow body in the direction F which proceeds from the intake section A to the discharge section B.
  • the bottom 210 is fully open in such a way as to obtain an intake section A as large as possible.
  • the second hollow body 2 comprises a chamfer 205 which connects the front wall 201 to the top 204.
  • the module 1 comprises six vertices 206.
  • the second hollow body 2 has the pair of passage holes 4 made on the corresponding opposite sides 203 in the upper part defining the top 204, and in such a way as to be opposite and coaxial with each other.
  • the second hollow body 2 also has two other passage holes 4 made on the corresponding opposite sides 203 in the lower part, defining the base 210, and in such a way as to be opposite and coaxial with each other.
  • first 3 and the second 2 hollow body have the two pairs of holes 308, 4 made on the corresponding top end 304, top 204 and bottom end 305, bottom 210 positioned, with the module 1 assembled, coaxial with each other to define a corresponding single through channel which can be engaged by the supply conduits 501 and discharge conduits 502 of the heat carrier fluid.
  • the two pairs of holes 4 of the second hollow body 2 have a diameter D4 greater than the diameter D308 of the corresponding two pairs of holes 308 of the first hollow body 3 (see Figure 2C ).
  • This feature makes it possible to always verify the sealed closing zones (and the seals, as described in more detail below) of the first hollow body 3 when engaged by the supply and discharge conduits of the heat carrier fluid.
  • the second hollow body 2 comprises a material with a low coefficient of heat exchange in such a way as to reduce the thermal losses.

  • the second hollow body 2 comprises an intake section A and a discharge section B of the air.
  • the intake section A is greater than the discharge section B in such a way as to favour the "flue” effect, which makes it possible to draw in cold air from the base of the radiant module 1 and covey it upwards towards the discharge section B.
  • the intake section A has a surface extension equal to that of the entire bottom 210 of the second hollow body 2. According to another embodiment, the intake section A is less than the surface of the bottom 210 of the second radiant body 2.
  • the discharge section B is identified by slots 207, substantially rectangular in shape but with half circles instead of the short sides, made on the head 204.
