Thermally insulating housing for cooling device

Abstract

The invention relates to a thermally isolating housing (11) for a cooling device (10) comprising an internal and external surface layer (17, 19) in addition to a thermally insulating layer (20) inserted between entrances of the surface layers (17, 19) in the form of fluidic components, introduced through at least one entrance opening (23) arranged close to a machine chamber (21) for receiving a condensed refrigerating medium (16). A problem of the known cooling device is that the thermally insulating material (20) which turns into mousse is introduced by the high processing pressure thereof, preferably in the upper part of the thermally insulating housing (11). A shrinkage formation therefrom can not be prevented in the deep lying sections of the housing. According to the invention, at least in the neighbouring area of the entrance opening (23) a flat profile (24) is provided for using as a brake for the mousse.

Description

technical field [0001] The present invention relates to a thermally insulated housing for a refrigeration unit, which has an inner and an outer coating and a thermal insulation layer arranged between the two coatings in the form of a fluid initial composition, which can be passed through At least one inlet is inserted between the claddings, where the inlet is arranged in the vicinity of a machine chamber for accommodating a refrigerant compressor. Background technique [0002] The state of the art of refrigeration units is that the insulating material for thermal insulation is inserted between the inner and outer cladding in the form of a fluid initial composition. Especially for large-volume refrigerating devices such as vertical refrigerating devices and vertical freezing devices and refrigerating combination devices, the fluid insulation material is loaded through an inlet, which is often opened in a so-called bottom tank, The bottom trough covers a machine chamber for a...

Problems solved by technology

However, for a fast process, which is advantageous for this processing technology itself, the shell skeleton, which consists of the outer cover and the chip-free molded plastic inner lining delimiting the cold room, is in the so-called "grooved state", that is to say , the rear wall of the shell skeleton is placed on a foam mould, it turns out that, especially in the case of large-volume shells, the part close to the machine chamber is unevenly filled with thermal insulation

Thus, the formation of shrinkage cavities that lead to a reduction in the thermal insulation capacity of the housing inevitably occurs in the heat insulating material

The formation of such shrinkage cavities is particularly disadvantageous if at least a part of the insulating housing is designed as a freezer compartment
