Definitions

  • the present invention relates to a cooling device comprising an evaporator.
  • Cooling devices consist of two compartments situated one over the other, being the freshfood compartment and the freezer compartment.
  • the freezer compartment is situated above and the freshfood compartment is situated below.
  • the cooling of the freezer compartment is performed by means of the evaporator wound around the compartment.
  • the evaporator is disposed inside the rear wall.
  • the cooling of the freshfood compartment is performed by natural convection.
  • the warm and humid air rising along the door is provided to dehumidify by being cooled on the rear surface.
  • the Spanish Patent Application No ES2063608 a cooling device is explained that comprises a metallic element which is located between the freshfood compartment and the freezer compartment, and which provides the temperature of the refrigerator compartment ceiling to be kept above the dew point by acting as a thermal bridge that absorbs at least a portion of the heat dissipated by the condenser.
  • the aim of the present invention is the realization of a cooling device, on the freshfood compartment ceiling surface of which, the formation of condensation is minimized.
  • the freezer evaporator comprises a sheet and a tube installed onto the sheet.
  • the sheet is in quadrilateral form and disposed into the freezer compartment inner surface such that it will cover the base, side walls and ceiling of the freezer compartment.
  • the tube is installed to the sheet portion, corresponding to the side walls and ceiling of the freezer compartment, in a serpentine form, but does not correspond to the freezer compartment base.
  • the tube is installed such that the refrigerant flow direction will be parallel to the short edge of the sheet, and is fixed onto the sheet by a method such as welding.
  • the cooling device of the present invention no tube is disposed in the freezer evaporator on the sheet in the portion which corresponds to the freezer compartment base, in other words, in the portion which is near the freshfood compartment ceiling.
  • the ceiling is prevented from being cooled more than desired and hence, both waste of energy and sweating of the ceiling are prevented.
  • the tube since the tube is installed onto the sheet in a serpentine form such that the refrigerant flow direction will be parallel to the short edge of the sheet, when the sheet is shaped to cover the freezer compartment, the tube passes once through the portions wherein the sheet is bent. Thus, the tube is also prevented from being deformed by being bent in many points.
  • the tube is installed on the sheet with variable serpentine distances such that in the tube portion, which corresponds to the freezer compartment side walls, the serpentines will be closer to each other as the freshfood compartment is PatXML 3/7 BB1768-7.827
  • the cooling device furthermore, comprises a compressor, a condenser which transfers the thermal energy to the outer environment and a capillary which provides the refrigerant leaving the condenser to expand.
  • the capillary is attached to the freezer evaporator preferably by welding.
  • the capillary is connected to the freezer evaporator such that it will be in the same direction with the tube.
  • the capillary and the tube are provided to be attached in a secured and easy manner.
  • the capillary is connected to the freezer evaporator such that it will be inclined to the tube.
  • the noise, generated during the passing of the refrigerant from the capillary to the tube is decreased.
  • Figure 1 - is the schematic view of a cooling device.
  • Figure 2 - is the top view of the freezer evaporator when it is open.
  • Figure 3 - is the detailed view illustrating the tube - capillary connection in an embodiment of the present invention.
  • Figure 4 - is the detailed view illustrating the tube - capillary connection in another embodiment of the present invention.
  • the cooling device (1) comprises
  • a freezer compartment (3) which is shaped as an open-front box having a base, a ceiling and rear and side walls and which is disposed on top of the freshfood compartment (2), and wherein foods to be frozen are disposed, and which is kept at a lower temperature than the freshfood compartment (2),
  • an evaporator (4) which is disposed onto the rear wall of the freshfood compartment (2) and which draws the thermal energy in the freshfood compartment (2), and
  • the freezer evaporator (5) has
  • the tube (8) is installed such that the refrigerant flow direction will be parallel to the short edge of the sheet (7).
  • the tube (7) in a serpentine form such that the refrigerant flow direction will be parallel to the short edge of the sheet (7), when the sheet (7) is bent to be disposed onto the inner surface of the freezer compartment (3), the tube
  • the tube (8) is installed such that the pitch distance (d) of its serpentine coils will be less PatXML 5/7 BB1768-7.827
  • the cooling device (1) furthermore, comprises a compressor, a condenser which transfers the thermal energy to the outer environment and a capillary (6) which provides the refrigerant leaving the condenser to expand.
  • the capillary (6) is attached to the freezer evaporator (5) preferably by welding.
  • the capillary (6) is connected to the freezer evaporator (5) such that it will be parallel with the tube (8).
  • the connection between the capillary (6) and the freezer evaporator (5) is provided to be performed easily and in a secured manner ( Figure 4).
  • the capillary (6) is connected to the freezer evaporator (5) such that it will be angled to the tube (8).
  • the noise which will be generated by the flow, coming from the capillary (6) at high speed, when it enters the tube (8), is minimized ( Figure 5).
