Definitions

  • the absorption cooling unit 10 is located behind the rear wall 8 of the refrigerator and is attached to it. In Fig. 1, only some main components of the absorption cooling unit 10 are shown schematically; since nothing more is needed to explain the invention.
  • the wedge-shaped closure part 41 which also consists of insulating material.
  • a profile rod 18 made of a good heat-conducting material is interposed.
  • the profile rod 18 has a flat side, which faces the freezer compartment inner jacket, and a semicircular recess facing away from it, which offers a large contact area for the evaporator tube 16 located therein.
  • the primary air flow which is cooled as it flows past and between the ribs of the upper rib row 23, is displaced by the bulge 21 of the rib body 20 against the interior of the normal cooling compartment, it generates a secondary air flow which runs along the ribs of the lower rib row 24 from is directed upwards below and is thereby combined with the primary air flow in an increasingly cooling manner below the bulge.
  • FIG. 3 shows a section through the fin body and the evaporator along the line 111-111 in FIG. 2.
  • the base plate 114 of the fin body 107 in this example consists of an extruded aluminum profile.
  • the base plate 114 has two webs 115 on the inside of the bulge 108 for holding the evaporator tube 104 in place.
  • the webs 115 are temporarily elastically expanded by the evaporator tube 104.
  • the rib body can of course also by any other methods, such as. B. casting, gluing, soldering, welding, riveting, screwing are manufactured or assembled.
  • the depth of the cooling fins 23, 24 and 109 is selected to be essentially the same as the depth of the bulge 21 or 108 of the fin body 20 or 107. This ensures an optimal size of the space occupied by the fin body 20 or 107.

Claims (10)

1. Réfrigérateur (1) avec l'appareil de réfrigération à l'absorption (10) dont le tube d'évaporateur (17, 104) ou une section de ce tube est arrangé horizontalement ou incliné vers le horizontal et porte un ou plusieurs organes en matériel de haute conductivité thermique afin d'élargir la surface et d'intensifier ainsi la transmission de chaleur, organes en forme de corps ailettés (20, 107). consistant essentiellement d'une plaque de base (22, 114) qui est fondamentalement en parallel avec une paroi (7, 106) du réfrigérateur (1) et des ailettes de refroidissement (23, 24, 109) attachées fondamentalement en position verticale et d'une façon thermoconductive, au côté de la plaque de base (22, 114) qui est tournée vers l'intérieur du réfrigérateur, caractérisé du fait que la plaque de base possède au moins une section indentée (21, 108) vers l'intérieur du réfrigérateur dans laquelle le tube d'évaporateur (17, 104) ou une section de celui-ci est emboîtée.
2. Réfrigérateur selon revendication 1, caractérisé du fait que des ailettes de refroidissement (23, 24, 109) sont prévues au-dessus et/ou au-dessous de la section indentée (21, 108) du corps ailetté (20,107).
3. Réfrigérateur selon revendication 1 ou 2, caractérisé par un écart entre la section indentée (21, 108) et les ailettes de refroidissement (23, 24, 109) du corps ailetté (20,107).
4. Réfrigérateur selon revendication 3, caractérisé du fait que l'écart entre la section indentée (21, 108) et les ailettes (23, 24, 109) du corps ailetté est au moins 3 mm.
5. Réfrigérateur selon une ou plusieures des revendications 1 à 4, caractérisé du fait que la profondeur des ailettes de refroidissement (23, 24, 109) est essentiellement égale à la profondeur de la section indentée (21, 108) du corps ailetté (20,107).
6. Réfrigérateur selon une plusieures des revendications 1 à 5 caractérisé du fait que le bord non-ailetté (25) du corps ailetté (20, 107) est enraciné dans les parts d'isolation (4,113).
7. Réfrigérateur selon une ou plusieures des revendications 1 à 6 caractérisé du fait que la section indentée (21, 108) du corps ailetté (20, 107) est formée ainsi qu'elle embrasse à son côté intérieur au moins la moitié de la circonférence du tube d'évaporateur (17,104).
8. Réfrigérateur selon une ou plusieures des revendications 1 à 7 caractérisé du fait que la section indentée (21, 108) du corps ailetté (20, 107) porte des traverses (115) ou bien cames sur son côté intérieur pour tenir ferme le tube d'évaporateur (17, 104).
9. Réfrigérateur selon une ou plusieures des revendications 1 à 8 caractérisé par des fentes (40, 112) à travers l'isolation (4, 113) pour le passage du tube d'évaporateur (15, 104) et par bouchons (41, 118) en matériel isolant pour la fermeture de ces fentes.
10. Réfrigérateur selon une ou plusieures des revendications 1 à 9 caractérisé du fait que l'échangeur de chaleur à gas (14, 110) de l'appareil de réfrigération est arrangé à l'extérieur de l'isolation thermique (4,113) et porte une isolation séparée (27, 111) qui consiste préférablement d'un tuyau en matériel poreux et élastique.
