Definitions

  • the present invention relates to a tube heat exchanger through which a primary fluid is used for heating a secondary fluid such as swimming pool or sea water.
  • Heat exchangers are already known and reference is made, for example, to documents FR-A-2 441 819, FR-A-2 482 717, DE-A-3 038 344, and US-A-4 739 634.
  • the exchangers described in these documents consist of a cylindrical body provided with an inlet orifice and an outlet orifice for the secondary fluid. Inside the body, a helical coil is provided, traversed by a primary fluid intended to transfer its calories to the secondary fluid circulating in the body.
  • the secondary fluid is circulated as much as possible in contact with the coil.
  • the latter is housed in the annular space which is formed between the internal wall of the body and the external wall. an annular ferrule.
  • the secondary fluid therefore circulates in a helix between two turns of the coil.
  • the object of the invention is therefore to provide a heat exchanger specially intended for heating a corrosive secondary fluid such as swimming pool water or sea water.
  • FIG. 1 A heat exchanger according to the invention is shown in FIG. 1 in longitudinal section.
  • the base 3 is provided with means, such as holes. 4 for the passage of screws 5, which allow the exchanger to be fixed to the ground.
  • a sleeve 6 forming an inlet orifice for the secondary fluid through which the water to be heated, for example water from a swimming pool, is introduced.
  • a sleeve 7 forming outlet port through which the water heated in the exchanger returns to the pool.
  • the internal diameter of the sleeves 6 and 7 is dimensioned so that the exchanger can be connected to a circuit in which the secondary fluid can circulate, without excessive pressure drop, with relatively large flow rates, that is to say say between 5 and 20 m3 / hour, by means of a pump.
  • These diameters are for example of the order of 40 mm.
  • a ferrule 8 is provided, made up of a cylindrical tube provided with a radial internal partition 9.
  • a coil 10 consisting of a helical tube.
  • the coil 10 ends in a bend 11 passing through, with sealing, the cover 2 and has an inlet 12 through which the primary fluid is introduced.
  • the coil 10 forms a bend 13 extended by a rectilinear part 14 which also passes through the cover 2 with sealing and opens, in the vicinity of the inlet 12, on an outlet 15 through which the primary fluid leaves after having ceded his calories.
  • the rectilinear part 14 also passes through the internal partition 9 of the shell 8.
  • the ferrule 8 is fixed to the coil 10 by suitable means (not shown).
  • a temperature sensor 16 is mounted, the output signal of which can be used to control the circulation of the primary and secondary fluids in the exchanger.
  • the body 1 and the ferrule 8 are made of a plastic-based material, reinforced or not, such as PVC or, advantageously, polyester reinforced with glass fibers.
  • the coil 10 is made of titanium.
  • spacers 17a are provided between the internal wall of the body 1 and the coil 10, in the form of a vertical strip of small width compared to the diameter of the body 1 and provided with housings for each. turns of the coil 10 and, on the other hand, between the external wall of the shell 8 and the coil 10, spacers 17b being in the form of a strip also of small width compared to the diameter of the shell 8.
  • the spacers 17a and 17b keep the coil 10 at a distance of approximately 2 mm from the body 1 and the ferrule 8.
  • the function of the spacers 17a and 17b is multiple. It is to facilitate the mounting of the coil 10 which is, once the spacers 17a put in place, in the form of a single rigid piece. It is also to avoid relative movements between, on the one hand, the body 1 and the shell 8 and, on the other hand, the coil 10, movements which are generated by vibrations of pumps and accessories surrounding the exchanger and which can cause friction which deteriorates the elements of the exchanger.
  • the spacers 17a and 17b create zones located between the shell 8 and the coil 10 and between the body 1 and the coil 10 which are, from the point of view of corrosion, dead.
  • the spacers 17a and 17b create zones located between the shell 8 and the coil 10 and between the body 1 and the coil 10 which are, from the point of view of corrosion, dead.
  • the spacers 17a have housings for each turn of the coil 10 makes it possible to overcome the differences in winding diameter of each turn, these differences being compensated for. by the differences in thickness that take, when mounting the exchanger, the spacers 17a between their outer face and their housing.
  • the water to be heated flows upwards into the body 1 (arrows A), on the one hand, in a helix between two consecutive turns of the coil 10 and, on the other hand, between the coil 10 and the body 1 or the shell 8.
  • the primary fluid flows downward (arrows B), that is to say against the current of the secondary fluid water.
  • the primary fluid is, for example, a refrigerant from a heat pump (not shown) but could also be steam or hot water.
