Embodiment Construction

[0064] figure 1 A vacuum insulation 1 is shown, the vacuum region of which is delimited, ie delimited, by a vacuum-tight housing 2 . Preferably the housing 2 is a high barrier film.

[0065] Furthermore, a thermoelectric element 3 can be seen with semiconductor particles which in the figure connect or extend between two heat conductors 4 . In a direction extending transversely to the orientation of the semiconductor particles, the thermoelectric element 3 has two faces 31 , 32 between which a temperature drop can be set. In order to effectively transfer the temperature prevailing at the surfaces 31 , 32 to the edge regions of the housing 2 , the individual heat conductors 4 are connected not only to the housing 2 but also to the surfaces 31 , 32 of the thermoelectric elements 3 .

[0066] The heat conductor 4 has a cross section increasing from the thermoelectric element 3 towards the edge of the vacuum insulation.

[0067] Furthermore, heat exchangers 5 arranged outside th...

Abstract

The invention relates to a refrigerating and / or freezing device with a vacuum insulation (1) having a housing (2) delimiting a vacuum area, wherein a thermoelectric An element (3), in particular a Peltier element (3), is used to generate a temperature difference between two regions (5) arranged on the outer side of the housing (2).

Description

technical field [0001] The invention relates to a vacuum insulation with thermoelectric elements, preferably in the form of Peltier elements, which is preferably used in refrigerators or freezers. Background technique [0002] In refrigerating and / or freezing equipment, vacuum insulation is provided in the area between the outer cover of the equipment and the inner container to be cooled, so that by means of the principle of vacuum insulation, the outside and inside of the equipment to be insulated achieve a sufficiently high thermal insulation between them. [0003] A thermoelectric element, in particular a Peltier element, is an element which is able to generate a temperature difference by means of electrical energy. A Peltier element consists of two or more small cuboids made of p- and n-doped semiconductor material and connected to each other alternately at the top and at the bottom by metal bridges. The cuboids are connected to one another such that a series connectio...
