Definitions

  • the invention relates to a heat-insulating housing for at least two heat exchangers, like a condenser and an evaporator refrigeration device, the Housing walls which comprise spaced-apart envelope walls, which enclose a space in which the air pressure against the ambient pressure is lowered.
  • the invention is based, for heat insulating walls according to the task propose the preamble of claim 1 measures on the basis of which the Disadvantages of the prior art are avoided and at the same time the utility of a refrigerator is increased.
  • the solution according to the invention results for the refrigerator of the refrigerator a space-saving through the direct application of the duct or pipe arrangement Structure, which is reflected in an increase in its storage capacity.
  • the application of the channel or Pipe arrangement in heat-conducting contact with a good heat-conducting material manufactured cladding walls due to the heat transfer from the duct or pipe arrangement a significant increase in the heat exchange area on the respective cladding wall which significantly increases the efficiency of the refrigerator.
  • the Heat transfer from the duct or pipe arrangement to the envelope wall are also amplified by the fact that the channel or pipe arrangement good heat-conducting material, such as metal.
  • a heat-insulating housing is particularly useful if after a preferred embodiment of the object of the invention is provided, that the channel or pipe arrangement on both of the opposite Envelope walls of a housing wall are applied.
  • the application of the solution according to the invention has an effect if provided according to a further advantageous embodiment of the object of the invention is that the channel or pipe arrangement with respect to the surface of the each envelope is set back.
  • the channel or pipe arrangement has a pipe wall has, whose contour at least in part by the wall surface of the Envelope is formed.
  • the channel or pipe arrangement with the predominant part the contour of their line wall in a on the evenly formed envelope wall refrigerant-tight fixed circuit board is molded.
  • the channel or pipe arrangement with a predominant Part of the contour of its line wall in at least one of the opposite Envelope walls molded into a housing wall and largely flat trained circuit board is covered refrigerant-tight.
  • the invention provides that the indentation in the board or the envelope for forming the wall contour section of the sewer or pipeline without undercuts is generated.
  • the indentation in the circuit board or the cladding wall is particularly favorable for large ones Generate quantities, such as those found in the field of refrigeration equipment, if according to a last preferred embodiment of the subject of the invention it is provided that the indentation into the board or the envelope wall non-cutting shape is generated.
  • a heat insulating material 13 such as Glass fiber material, open cell Foam based on polyurethane, polyisocyanurate, polystyrene or others open-celled organic polymer foams, aerogels or other inorganic porous Filled materials and has one against the outside atmosphere of the heat insulating Housing 10 lowered, between the values 0.001 mbar and 100 mbar moving air pressure.
  • the intermediate space 12 is of an inner lining serving inner shell wall 14 and a spaced outer Boundary wall 15 bounded, which are connected vacuum-tight with each other at their free ends and which are made of stainless steel plates or corrosion-protected Sheet steel boards are made, which correspond to the dimensions of the housing walls 11 are angled.
  • the housing wall serving as the rear wall faces 11 on the corresponding sections of the envelope walls 14 and 15, on the an outside facing away from the intermediate space 12, a heat exchanger 16 or 17 on.
  • the heat exchanger designated 16 serves as a condenser, while the heat exchanger 17 is designed as an evaporator.
  • Both heat exchangers 16 and 17 are through the wall surface of the envelope walls facing away from the intermediate space 12 14 and 15 in the area of the rear wall and one each in a refrigerant-tight manner by welding fixed, plastically deformable plate 18 or 19 made of stainless steel or corrosion-resistant steel sheet formed.
  • fixed, plastically deformable plate 18 or 19 made of stainless steel or corrosion-resistant steel sheet formed.
  • the boards 18 and 19 is the course of one for guiding refrigerant channel arrangement 20 or 21 formed without cutting, of which the refrigerant channel arrangement introduced into the circuit board 18 20 to form the heat exchanger 16 and the circuit board 19 introduced refrigerant channel arrangement 21 serves to form the heat exchanger 17.
  • the refrigerant channel arrangement 20 and 21 of both heat exchangers 16 and 17 have one essentially Channel segment-like channel cross-section, whose cross-sectional area in predominantly determined by the indentation in the plates 18 and 19, the chord of the segment of the circle passing through the corresponding section of the wall surface the envelope walls 14 and 15 is generated.
  • Housing 10 Opposite the heat-insulating rear wall provided with the heat exchangers 16 and 17 Housing 10 is a heat-insulating door 22 at the edge of its opening struck. Like the housing 10, this has a wall 23 that surrounds it Interspace 24, which also with a space 12 of the Housing 10 heat insulating material 25 is filled and which after the filling process to an air pressure prevailing in the intermediate space 12 is evacuated. In the closed state, the door 22 lies over one at its edge bellows-like magnetic seal 26 arranged all around at the edge of the access opening to the housing 10 and encloses together with the housing walls 11 thereof a cooling space 26 arranged in the housing 10.
  • FIG. 2 is an alternative embodiment of one for use in a household refrigerator suitable heat-insulating housing 30 is shown, in which identical parts executed for the heat-insulating housing 10 are identified by the same reference numerals are.
  • the heat-insulating housing 30 has the same as the heat-insulating one Housing 10 integrally connected housing walls 31, which with an intermediate space enclosed by lateral surfaces explained in more detail below 32 are equipped. This is filled with a heat insulating material 33 and in terms of its air pressure is reduced to values as described in the description of first embodiment are mentioned.
  • peripheral surfaces surrounding the intermediate space 32 serve in the present case an inner envelope wall 34 and a spaced apart outer envelope wall 35, which consists of an approximately the pressure difference between the space 32 and its outside atmosphere, which is diffusion-tight, board-like material are formed, which according to the dimensions the housing walls 31 is shaped.
  • the rear wall of the housing 30 serving housing wall 31 with the section of the envelope walls assigned to it 34 and 35 each equipped with a chipless molded channel 36 and 37, which both extend with their channel bed into the intermediate space 32 and which are arranged in a meandering manner over the surface of the rear wall.
  • Channels 36 and 37 are formed on their side facing away from the intermediate space 32 and are each open from a circuit board 38, which is fixed on the envelope wall 34 or 35 in a refrigerant-tight manner or 39 completed, whereby a heat exchanger 40 or 41 is formed, the duct or pipe arrangement used to guide refrigerant through the channel 36 and 37 is generated.
  • a heat exchanger 40 or 41 serves the Cooling chamber 26 facing heat exchanger 40 as an evaporator and the opposite one Heat exchanger 41 as a condenser.
  • the heat-insulating To build housings 10 and 30 from individual heat-insulating panels, of which the panel serving as the rear wall with heat exchanger 16 and 17 or heat exchanger 40 and 41 is provided. It would also be possible to use the the panel equipped according to the invention as a one-piece rear wall module to be used in refrigeration equipment, the heat insulation of which is otherwise based on foam Polyurethane foams based.
