Definitions

  • thermoelectric modules having reverse thermoelectric effect also known as the Peltier effect, from the name of its discoverer.
  • the above modules make it possible to build both portable and static refrigerators, the latter version being suitable for use in homes or hotels, for example.
  • the power used to run the portable type refrigerator can be supplied directly by the generator of an automobile or water craft.
  • the power used to run the static type of refrigerator is supplied from the home or hotel electric circuit.
  • the device according to the invention differs from the refrigerators currently in use in that it uses no refrigerant fluid of any type whatsoever, and no cold-­accumulators requiring to be cooled by external devices. In all of its possible embodiments, the device is totally autonomous.
  • thermoelectric modules with reverse thermoelectric effect consists essentially of the following elements: - a container with a high level of thermic insulation; - access means from the outside to the inner area of the container; - Peltier-effect generating modules; - means for supplying the generating modules with direct current; - means for distributing the refrigeration units generated within the container; - means for dispersing the calories externally; - thermic insulation means between the aforesaid means for distribution and dispersion; - cooling means; and - optionally, electronic means for piloting the Peltier-effect generating modules.
  • the useful space inside the container is accessible through either a top lid or a side door.
  • the cooling means may be either aeriform or liquid.
  • the user can proportion the current according to need, and/or subordinate them to a temperature sensor located inside the refrigerator compartment so as to control and program the thermic conditions.
  • the refrigerator according to the invention may be either portable or static.
  • the unit is powered by a battery, for example that of a vehicle or water craft.
  • it is powered by the home or hotel electric system or other source of energy.
  • the refrigerator according to the invention offers a number of advantages, including noiseless operation (due to the absence of a compressor), low cost of manufacture, extremely simple construction design, high degree of operating reliability, small amount of maintenance required, and the absence of refrigerants, which may be toxic or pollute the environment. Moreover, the portable version, powered on board a vehicle or water craft, can be subsequently removed and used at a distance for a reasonably long period of time, owing to its high capacity to maintain the compartment cold.
  • both versions of the refrigerator comprise a container 8 built of material having a low thermic conductivity, which encloses a compartment 9 accessible through a top lid or a side door 11.
  • the frigorific generator faces onto one side, either vertical or horizontal, of the inner compartment. It comprises one or more Peltier-effect thermoelectric modules 1; a refrigeration-dissipating plate 2 facing onto the inside of the compartment; and a dissipating element 3 which dissipates the calories generated by the Peltier process, being suitably ventilated by a fan 4 which conveys outside air onto the dissipator through louvres 5.
  • thermoelectric modules are piloted by means of a special electronic circuit 6 connected directly to either a power outlet on the vehicle or water craft (in the case of the portable version) or, through a special electric circuit 10, to the home or hotel electric system (in the case of the static version).
  • thermoinsulating material 12 fitted between the two dissipator elements separates the hot area of the device from the cold area.
