Definitions
- the invention relates to a water heater configured for heating water by solar energy.
- the invention also relates to a roof equipped with such a water heater and to a section of road equipped with such a water heater.
- a water heater is used to heat water using a source of electrical or thermal energy, for example solar.
- the water heater is then equipped with one or more solar panels.
- An object of the invention is to provide a water heater that is simple and inexpensive to manufacture as well as to maintain.
- the invention relates to a water heater configured to heat water by solar energy, the water heater comprising a bitumen-based body and at least one water channel. flow shaped as a serpentine thermally conductive material, the flow channel circulating in the bitumen-based body between an inlet and an outlet of the water heater.
- bitumen-based body is heated by the sun either by radiation (when the water heater is directly exposed to the sun) or by conduction (when the water heater is for example integrated in a road or in the inside a roof which are themselves exposed to the sun's rays) providing heating by thermal exchanges of the coil and therefore of the water circulating in the flow channel.
- the water is therefore heated by a simple and robust water heater.
- such a water heater can be easily and inexpensively manufactured by a private individual.
- an individual can easily obtain the various elements constituting the water heater.
- the water heater is moreover effective in particular thanks to the use of the bitumen-based body.
- the inventor was thus able to develop a prototype in which the water entering the water heater at ambient temperature leaves said water heater at at least 70 degrees Celsius.
- the body is shaped as a panel.
- the width of the body is between 80 and 90% of the length of the body.
- the flow channel, the inlet and the outlet are in one piece.
- the flow channel is plane.
- the flow channel extends parallel to at least one face of the body.
- the flow channel is arranged substantially in the center of the body.
- the flow channel is based on metal.
- the body is multilayer.
- the body comprises at least one sealing membrane.
- the body comprises at least one layer in the form of a bituminous shingle, a bitumen fabric or a bitumen plastic.
- the invention also relates to a roof equipped with such a water heater.
- the invention also relates to a section of road equipped with such a water heater.
- FIG. 1 is a perspective view, partially broken away, of a water heater according to a particular embodiment of the invention.
- Figure 2 is a top sectional view of the water heater illustrated in Figure 1,
- Figure 3 is a cross-sectional view of the water heater illustrated in Figure 1.
- the water heater generally designated 1
- the water heater comprises a body 2 based on bitumen.
- the body 2 is monolayer.
- the body 2 comprises for example a single layer of bitumen or else comprises a single layer of a composition comprising bitumen (for example the composition is bituminous concrete or a mixture of bitumen and for example sand and gravel).
- the body 2 is multilayer.
- the body 2 comprises for example at least one bitumen layer and / or at least one layer of a composition comprising bitumen (for example the composition is bituminous concrete or a mixture of bitumen and for example sand and gravel).
- the body 2 comprises a first thickness 11 based on bitumen and a second thickness 12 based on bitumen.
- At least one of the thicknesses is an asphalt shingle (either a glass fiber structure covered on one or both sides with bitumen or coated with bitumen), a bitumen fabric (or a fabric structure like felt covered on one or both sides of bitumen or coated with bitumen) or even a bituminous plastic (either a plastic structure covered on one or both sides with bitumen or coated with bitumen).
- the two thicknesses 11, 12 are here identical in shape and composition.
- the two thicknesses 11 and 12 are fixed together for example by cold bonding (using an adhesive typically), by hot bonding (using a torch typically for a hot welding) or by any other means, for example by nailing. In this way, the two thicknesses 11 and 12 jointly form a unitary assembly which is the body 2.
- the body 2 is for example shaped as a panel or a rectangular parallelepiped of small thickness.
- the body 2 thus has a first main face 3 and a second main face 4 opposite and parallel to the first main face, four side faces providing the junction between the two main faces 3, 4.
- the width of the body 2 is between 1 and 2 meters.
- the length of the body 2 (greater in all cases than the width of the body 2) is between 1 and 2 meters.
- the height of the body 2 is between 2 and 10 centimeters.
- the water heater 1 also comprises at least one flow duct circulating in the body 2 between an inlet 6 and an outlet 7 of the water heater, inlet 6 and outlet 7 arranged outside the body 2.
- the heater - water 1 comprises a single flow channel circulating in the body 2 between the inlet 6 and the outlet 7 of the water heater 1.
- the inlet 6 and the outlet 7 are here simple tubes of circular section.
- the flow channel is for its part shaped as a coil 5 whose section is circular, the coil 5 being connected in a sealed manner to the inlet 6 and to the outlet 7 of the water heater.
- the flow channel, the inlet 6 and the outlet 7 are in one piece.
- the coil 5 is composed of a succession of straight portions and bent portions all extending in the same plane.
- the coil 5 is moreover arranged in the body 2 so as to extend parallel to the main faces 3, 4.
- the coil 5 is arranged substantially in the middle of the bitumen body between the first thickness 11 and the second thickness 12. The coil 5 is thus sandwiched between the two thicknesses of the body 2.
- the coil 5 is shaped so that its two ends extend parallel to one another.
- the coil 5 is shaped so that its two ends extend at the same side face (either outside or inside said side face).
- the inlet 6 and the outlet 7 therefore extend substantially at opposite corners of the water heater 1 connected by the same side face.
- the coil 5 is made of a thermally conductive material.
- the coil 5 is for example in a metallic material.
- the coil 5 is made of aluminum.
- water heater 1 is here only made up of the body 2, the flow channel and the inlet 6 and outlet 7.
- the water enters the water heater 1 at the level of the inlet 6 and circulates in the coil 5 up to the outlet 7, the water being thus gradually heated by heat transfers via the flow channel and body 2 which is itself heated by the sun (either directly or indirectly).
- the water heater 1 is arranged in a system (building, road, bridge ... or any other infrastructure) so that the coil 5 is substantially horizontal.
- the water heater 1 is arranged in a roof.
- the body 2 is thus heated directly by the sun when it is arranged on the roof or indirectly if it is arranged inside the roof.
- the water heater 1 is then arranged on a flat roof.
- the water heater 1 further comprises a sealing membrane 8.
- the membrane 8 is here arranged under the second main face 4 so as to form a bottom, a base for the body 2.
- the membrane 8 is typically shaped so as to extend in a plane parallel to the first main face 3 and to the second main face 4.
- the membrane 8 here has the same surface as the first main face 3.
- the membrane 8 is preferably made of plastic and for example based on EPDM (for ethylene-propylene-diene monomer).
- the membrane 8 is, for example, in the form of a roll of EPDM before it is inserted into the water heater 1.
- the water heater 1 then only consists of the body 2, the flow channel and the inlet 6 and outlet 7 as well as the membrane 8.
- the membrane 8 is arranged.
- the free main face of the membrane 8 is then covered by the first thickness 11.
- the coil 5 is then placed, which in turn is covered with the second thickness 12.
- the assembly is then welded. by heating the first thickness 11 and / or the second thickness 12 for example by torch. Thanks to the bitumen they contain, the two thicknesses 11 and 12 are welded together, allowing the coil 15 to be wedged between the two thicknesses 11 and 12. This can also allow the membrane 8 to be welded to the first thickness 11.
- Such a water heater can be delivered directly to the site in this form.
- a user then only has to place the water heater on the roof, thus simultaneously ensuring a waterproofing function of the roof (via the membrane 8 but also the thicknesses 11 and 12) and of water heaters.
- the water heater 1 is arranged in a section of road, preferably a private road.
- the body 2 is thus heated directly by the sun when it is arranged so that one of its main faces is substantially at the level of the surface. upper side of the road, said main face then directly forming part of the road, or heated indirectly by the sun when the body 2 is arranged inside the road, the water heater 1 then being covered in whole or in part by the road.
- the body 2 can therefore be directly formed by the road.
- the first layer 11 based on bitumen or bitumen is poured.
- the coil 5 is then arranged, which in turn is covered with a second thickness based on hot bitumen 12, which allows the two thicknesses to merge and thus to wedge the coil 5 inside the bitumen body.
- the water heater 1 is directly created on site at the same time as the road. It is noted that the body 2 is then single-layer, the two thicknesses 11 and 12 having merged during the casting of the second thickness 12.
- the water heater can thus arrange the water heater on a terrace, a roof, a bridge, a road, a passageway, a motor or sail boat ... or any other infrastructure.
- the water from the water heater can thus be used for multiple applications such as heating a house, a vehicle, a swimming pool ... and whatever the location of the associated water heater.
- the water heater 1 can also be used as an instantaneous water heater 1 or else be connected to a hot water tank.
- the invention is not limited to the embodiment described and variant embodiments can be provided without departing from the scope of the invention as defined by the claims.
- the water heater does not have a tank, the water heater can directly incorporate the water tank.
- the water heater could also be connected or directly include other elements such as for example one or more sensors making it possible to measure the temperature of the water.
- the water heater can thus be different from what has been described.
- the water heater may not have a membrane even if the water heater is arranged in or on a roof and even in or on a flat roof (the waterproofing may be filled by the body of the water heater alone or by a membrane external to the water heater or by any other sealing device).
- the water heater may include a membrane for an application other than the roof, for example an application to a road.
- the membrane can be secured other than what has been described to the body.
- the membrane could be glued cold (using an adhesive typically), hot (using a torch typically for hot welding) or secured by any other means, for example by nailing.
- We can also arrange the membrane directly inside the body. The membrane can thus be placed in the body under the flow channel, for example being in contact with the flow channel.
- the water heater can be delivered as a single unit element to the road site and incorporated as such in the road during the manufacture of the latter.
- the water heater can also be mounted directly on site (and not delivered in a unitary block) either by a company or by a private individual directly.
- the invention can advantageously be implemented by simple and inexpensive means accessible to any individual.
- the flow channel may be in a completely different thermally conductive material than what has been indicated is for example made of steel, iron or else in a material other than metallic and for example be based on natural fibers.
- the flow channel may not be arranged in the middle of the body but in other places of the body.
- the flow channel will be arranged so that it is sandwiched between two layers of the body.
- the body is in the form of a panel of rectangular section, the body may be in any other form and for example have a square or circular section.
- the body may just as well be in flat form at rest as in roll form.
- the body may have any other dimensions than those indicated. Indeed, the invention advantageously adapts to any thermal need and / or space offered.
- the water heater can be made up of several bodies such as those mentioned above optionally joined together, for example glued cold (using an adhesive typically), hot (using a torch typically for a hot welding) or secured by any other means, for example by nailing.
- the water heater may thus have several flow channels.
