Definitions

  • thermoelectric cooling module based on the usage of commercially available semiconductor elements.
  • a heat transmission system has had to be developed which optimizes the power generated, attaining levels of performance unknown to date in the field of gas - free cooling (ecological refrigeration).
  • Patent US-A-3137141 refers to a thermoelectric water cooler comprising a supporting wall with a plurality of transverse openings therethrough, a cooling member including a first water coil cast within a block of metal with one end connected to a source of water and having its other end adapted to be connected to an outlet for dispensing cooled water, a heat dissipating element including a water coil cast within a second block of metal and having one end adapted to be connected to a source of water and having its other end adapted to be connected to an outlet for the water heated by the passage therethrough, and a thermoelectric module between them.
  • the two dissipating elements are arranged to the thermoelectric module in a manner that it is not possible to avoid the thermal bridge between them.
  • Patent US-A-3450572 refers to a thermoelectric battery which is clamped between two heat exchangers having beyond the clamping area, two opposite faces with a layer of thermally insulating material sandwiched between them.
  • the cooling system according to claim 1 comprises a thermoelectric plate of a type that is commercially available, to which a metal block is added, preferentially manufactured of aluminium, on the side which is to be used to generate cold; together with two dissipators, one on the heat emitting side and the other on the free side of the metal supplement.
  • the perfection of the contact between the surfaces in question is extremely important.
  • the use of some highly conductive substance is advisable to ensure the quality of the contact (such as high conductivity silicon or copper sulphate) thereby avoiding the appearance of harmful thermal resistances.
  • FIG. 1 a prototype has been developed, as is shown in figure 1, which consists cf a tank of liquid (water, for example) to which on opposing sides six modules in two groups of three have been affixed, leaving the dissipators (1) with refrigerating sides (2) within the tank.
  • a metal block (8) is located between the dissipator (3) and the refrigerating side (2) of the thermoelectric plate.
  • the dissipators (3) with heat emitting sides (4) remain on the outside, working in forced convection mode with the aid of low profile axial fans (5). Two such fans are used fcr each group of three modules, as was mentioned above, while the airflow is directed in front of the fans by means of small nozzles.
  • each module is achieved through the joining of the two dissipators in the method shown in figure 2.
  • the part made of insulating material (6) may be seen, together with the metal rods (7) that are embedded in the said part without touching one another, avoiding thermal bridges.
  • the supply of electricity to the modules is ensured by using a commercially available direct current power source.
  • a commercially available direct current power source In the definitive model, it will be possible to include a power source manufactured in - house within the system as a whole.
  • the cooling coil of a drink dispenser (such as one for beer or soft drinks) is placed within this equipment, then the liquid is cooled to a suitable degree.
