Definitions

  • a shoulder is formed in the sleeve receiving the Peltier element, and the Peltier element is held at that height in the shoulder, whereby the Peltier element or the protrusion engaging in the sleeve can abut against the shoulder To define position of the Peltier element inside the sleeve.
  • This shoulder is preferably formed approximately centrally in the sleeve, and both heat exchangers have a projection engaging into the sleeve in contact with the pel element.
  • the mounting sleeves for both heat exchangers are preferably from a same side of the
  • a second heat exchanger 14 has the shape of a cuboid made of aluminum with protruding at the front heat exchange ribs 15 and a ab ⁇ standing on the back, not visible in Fig. 1, but only in the sectional view of FIG. 4 projection 16.
  • the depth of the projection 16 is sufficient to keep clamped a disc-shaped Peltier element 17 between the two projections 12, 16 of the heat exchanger, when both heat exchangers 9, 14 are fixedly mounted on the support parts 1 a, 1 b. From the back of the second heat exchanger 14 are aligned with the sleeves 7 of the support member 1 from four feet 18, each having a central bore 19 (see FIG.
  • Heat taken up by the ribs 15 from the interior of the refrigerating appliance causes the evaporation of heat transfer fluid from the porous layer 32, which subsequently condenses on the opposite inner side of the cavity 31 at the level of the projection 16 cooled by the Peltier element 17 and heats the latter ,
  • the heat flow entering the heat exchanger 14 on a large surface is effectively concentrated on the comparatively small cross-sectional area of the protrusion 16, and in the protrusion 16, a high power flux density is achieved which allows the temperature jump in the Peltier element 17 to be small Efficiency to keep it high.
  • the outer heat exchanger 9, like the inner one 14, can be realized as a hollow housing 35, partially filled with gaseous and partly liquid heat carrier fluid with cooling fins 36, whose dimensions and wall thicknesses are the same.
  • the projection 12 is arranged at the lower region of this housing 35 so that heat flowing in via the projection 12 first reaches the supply of liquid heat transfer fluid in the lower region of the inner cavity 37 of the housing 35. This heat reaches the arranged on the opposite side of the housing cooling fins 36 via convection of the liquid heat transfer fluid or by its evaporation and an ⁇ closing condensation on the cooling fins 36 adjacent wall of the housin ses 35.
