Definitions

  • the invention relates to a refrigerator with a multi-layer cooling area, which consists of a support grid and evaporators with a tube which is fixed in turns on the support grid.
  • a gaseous refrigerant which evaporates at low temperatures, is compressed by a compressor and liquefied.
  • the heated, liquid refrigerant is passed through a condenser in the evaporator.
  • the evaporator generally consists of a continuous flat tube structure having an inflow and outflow opening, a support grid consisting of many intermittent and parallel wires and fixing the flat tube structure to the bottom, and an expansion valve located at the aforementioned inflow opening is appropriate.
  • the refrigerant entering the expansion valve passes through the flat tube structure and is converted into gas as a result of the volumetric expansion. As the refrigerant absorbs energy within this process, it cools the outside temperature and directs the cold air into the refrigerator compartment using the evaporator fan.
  • evaporators that consist of a continuous tube and multiple flat tube layers to cool each compartment from below and from above.
  • patent GB2145806 an invention is described as an example of such a structure.
  • evaporators containing flat tube layers made by the method in question must use an ancillary apparatus and assistive technologies to obtain greater than normal cooling performance with the existing device.
  • the present invention is an evaporator auxiliary that is used in the freezer compartment of a refrigerator and eliminates the above-mentioned disadvantages and creates new advantages for the relevant technical field.
  • the main object of the invention is to increase the cooling activity of a refrigerator operating with a refrigeration cycle.
  • Another object of the invention is to provide additional cooling of areas which require more cooling due to heat loss in the refrigerators.
  • the present invention which fulfills the objects set forth above and in the detailed description below, is a new refrigerator having a valve into which the refrigerant enters from the refrigeration cycle, a pipe having an exit toward the refrigeration circuit, and an evaporator which consists of multiple turns on a cooling surface.
  • the tube is characterized by at least one primary airfoil attached to said primary extension to form a primary extension between valve and outlet and an additional cooling element. In this way, additional cooling is ensured because the primary wing z. B. is connected to a surface that requires additional cooling.
  • the primary airfoil is generally perpendicular to the evaporator. While z. B. the horizontal evaporator cools the floor or the ceiling of the refrigerator can be cooled in this way by means of a wing, the side wall in the vicinity of the floor or the ceiling.
  • said primary airfoil is characterized by at least one secondary extension extending on the other side of the primary airfoil to connect the primary airfoil to the pipe from the other side.
  • the support surface is connected to the tube on two opposite sides, so that the heat transfer surface between the tube and the support surface is increased.
  • said primary airfoil is characterized by at least one attachment arch on the side to ensure connection to the pipe.
  • the arc surrounds the tube, thus increasing the heat transfer surface between the tube and the primary airfoil.
  • the preferred structure of the invention is characterized by at least one secondary airfoil between the primary airfoil and the exit.
  • said evaporator is located between primary and secondary airfoils. In this way, the evaporator and wings can cool three adjacent sides in the refrigerator.
  • said primary airfoil is located between the valve and the evaporator. In this way, at the location where the heat of the refrigerant exiting the valve is lowest, the heat transfer into the primary airfoil can take place.
  • said primary and secondary extensions are basically parallel to each other. In this way, e.g. a rectangular airfoil can be attached in between.
  • the preferred structure of the invention includes at least one secondary intermediate evaporator mounted between said secondary airfoil and the exit.
  • said evaporator is basically in a vertical position between the secondary and primary support surfaces, which are basically arranged parallel to one another.
  • Figure 1 shows the perspective view of the evaporator, which is the subject of the invention.
  • the structure in Fig. 1 has in sequence from bottom to top a bottom evaporator (20) near the bottom (12), a first Eisenevaporator (30), a second Eisenevaporator (40) and an upper evaporator (50) in the vicinity of Ceiling (16).
  • the evaporators (20, 30, 40, 50) consist of a continuous tube (80), which winds several times U-shaped.
  • the expansion valve (84) at the inlet of the tube (80) and the outlet (82), which is parallel and in the vicinity of the expansion valve, are located below the upper evaporator (50).
  • the tube (80) leading from the expansion valve (84) extends parallel to the back (18) towards a side wall (14) and forms a primary extension (62) parallel to the side wall (14) by being in an inlet bend (69) turns.
  • the primary extension (62) leads with an arc parallel to the front (1 1) in the direction of the ceiling (16) and thus forms a vertical extension (66), which in turn with another arch in the rear (18) runs and so a secondary Extension (64) forms.
  • By bending over the secondary extension (64) with an exit arc (67) it extends parallel to the rear face (18) and looks towards the other side wall (14).
  • the tube (80) forms a U-shape on the side wall (14) and connects from here to the upper evaporator (50).
  • a primary support surface (60) in the form of an aluminum plate is fixed on both edges.
  • the upper evaporator (50) consists of the tube (80) extending in multiple bends (52) parallel to the ceiling (16).
  • the tube (80) in the evaporator (50) extends with an exit arc (55) in the vicinity of the side wall (14), which is in opposite distance of the entrance sheet (54), in the direction of the bottom (11).
  • the tube (80) continues and forms a secondary support surface (70) in a U-shape, which is constructed in the same way as the primary support surface (60) and whose ends look towards the rear side (18).
  • the tube (80) which changes its direction at an exit (76) of the secondary wing (70) with a bow towards the bottom (12) and runs parallel to the back (18), connects to an inlet (42) with the second intermediate evaporator (40).
  • the tube (80) in turn forms the second intermediate evaporator (40), the first intermediate evaporator (30) and the bottom evaporator (20) and returns from here parallel to the back (18) to the outlet (82).
  • mounting arches (74) are formed at the secondary support surface (70), as at the primary support surface (60), by bending the upper and lower edges.
  • the upper and lower mounting arches (74) sequentially surround the tubular primary and secondary extensions (62, 64) and secure the airfoils (60, 70) to the tube (80).
  • the refrigerant passes through the tube (80), it cools the primary and secondary wings (60, 70) by heat conduction and forms on the side walls (14) a cold area.
  • the area between the upper evaporator (50) and the second Eisenevaporator (40) is not only cooled from above and below, but also from the side walls (14) and thus from all four sides.
  • the wings (60, 70) are near the valve (84), they ensure the transfer of the lowest calorific value of the refrigerant. Further, because they are near the upper evaporator (50), they help lower the temperature of the freezer area, which must be effectively cooled.
  • the holes (72) in the rectangular aluminum plates forming the primary and secondary airfoils (60, 70) cause the metal plates to be less affected by thermal expansion.
  • the primary airfoil (60) is directly connected to the valve (84), an additional cooling element is formed in the left upper corner of the refrigerator (10), which has a large heat loss.
  • the primary airfoil (60) may also be installed at other locations where the cooling loss in the refrigerator is greatest.
