Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
The roll-bond evaporator 1 for a mobile refrigerator according to the present invention is described below with reference to the accompanying drawings.
As shown in fig. 2, the present invention provides a roll-bond evaporator 1 having a new structure. In particular, compared to the roll-bond evaporator of the prior art, the roll-bond evaporator 1 according to the first embodiment of the invention extends on the third or fourth end side 3 of its tube panel 2 an additional panel 4, the inlet and outlet tubes 5, 6 of the refrigerant of the roll-bond evaporator 1 being separately provided and arranged on this extended panel 4. Since the structure in which the inlet pipe 5 and the outlet pipe 6 for the refrigerant are separately arranged is employed, the capillary tube 7 can be hermetically connected to the inlet pipe 5 by welding without using a caulking process, so that the back leakage of the refrigerant can be completely prevented; in addition, the inlet pipe 5 and the outlet pipe 6 are arranged on one additional panel 4 extending outward, and the additional panel 4 on the third end side or the fourth end side 3 is assembled in the heat-insulating layer (i.e., PU glue layer) of the lower part of the mobile refrigerator when the evaporators are butted to form the inner cavity of the mobile refrigerator and assembled on the mobile refrigerator, so that the inlet pipe and the outlet pipe of the evaporator can be hidden in the heat-insulating layer of the lower part of the box body of the mobile refrigerator, and the bulges and riveting indentations of the inlet pipe and the outlet pipe cannot be formed on the inner wall of the inner cavity of the mobile refrigerator, so that the aesthetic property of the inner wall of the inner cavity of the mobile refrigerator is improved.
Furthermore, preferably, in order to further improve the aesthetic appearance of the non-manifold panel 8, i.e. the inner wall of the internal cavity of the mobile refrigerator, the metal plate, for example a commercially pure aluminum plate, used for the non-manifold panel may have a greater thickness than the aluminum plate used for the non-manifold panel, so as to be able to withstand the pressure during the inflation of the manifold better than the manifold panel, so that a substantially flat-surfaced, non-convex non-manifold panel 8 may be obtained. Alternatively or more preferably, the non-tube panel may be an alloy aluminum sheet and the tube panel may be an industrial pure aluminum sheet, whereby when the tube is blown, a substantially flat-surface, non-bulging non-tube panel may be obtained due to the higher pressure that the alloy aluminum sheet can withstand relative to the industrial pure aluminum sheet. Since the aluminum alloy plate can withstand higher pressures, the thickness of the non-pipe panel may be equal to or even less than the thickness of the pipe panel. In a more preferred embodiment, the non-tube panels are made of aluminum alloy sheets of substantially about 0.825mm thickness, and the tube panels are made of commercially pure aluminum sheets of substantially about 0.625mm thickness.
In addition or alternatively, the non-pipeline panel, i.e. the inner wall of the inner cavity of the mobile refrigerator, can be subjected to surface treatment, namely firstly removing oil stains and the like on the surface, then performing sand blasting treatment, then spraying teflon paint, and then baking to form a teflon coating on the surface, wherein the teflon coating can be sprayed with different colors, such as grey and the like, according to needs; thereby further improving the beauty of the inner wall, and also leading the inner wall to have good metal texture and good corrosion resistance. Wherein, prior to treating the surface, the evaporator is charged and sealed with nitrogen gas at a pressure near or slightly greater than atmospheric pressure (e.g., 0.105-0.11MPA) to prevent ingress of moisture and impurities during blasting and baking of the evaporator and to prevent deformation and oxidation of the evaporator during high temperature baking (resulting in generation and removal of oxides into and clogging of the capillary).
The above-mentioned roll-bond evaporator according to the first embodiment of the present invention is provided with an additional panel on the pipe panel, and the inlet pipe and the outlet pipe of the refrigerant are provided on the additional panel. Alternatively, according to a variant of the invention, the roll-bond evaporator may be provided with two additional panels on its piping panel, while the inlet and outlet pipes for the refrigerant may be provided in one and the other of the two additional panels, respectively.
In particular, according to a variant of the invention (not shown), the roll-bond evaporator extends on the third end side or on the fourth end side of its piping panel two additional panels, which can be arranged adjacent or at a distance from each other, the inlet and outlet pipes of the refrigerant of the roll-bond evaporator being arranged respectively on one and on the other of the two panels extending. Due to the adoption of the structure that the inlet pipe and the outlet pipe of the refrigerant are separately arranged, the capillary tube can be connected to the inlet pipe through welding and sealing without adopting a riveting process, so that the back leakage of the refrigerant can be completely avoided; in addition, the inlet pipe and the outlet pipe are respectively arranged on two additional panels extending outwards, and the two additional panels on the third end side or the fourth end side are assembled in the heat-insulating layer (namely PU glue layer) at the lower part of the mobile refrigerator when the evaporators are butted to form the inner cavity of the mobile refrigerator and are assembled on the mobile refrigerator, so that the inlet pipe and the outlet pipe of the evaporators can be hidden in the heat-insulating layer at the lower part of the box body of the mobile refrigerator, and the bulges and riveting indentations of the inlet pipe and the outlet pipe cannot be formed on the inner wall of the inner cavity of the mobile refrigerator, so that the attractiveness of the inner wall of the inner cavity of the mobile refrigerator is improved.
Although the above embodiments preferably describe one or two additional panels extending out on the non-abutting end side, i.e. the third end side or the fourth end side, of the pipe panel; alternatively, however, according to a variant of the invention (not shown), one or two additional panels (which may be arranged adjacent or at a distance) extending out may be provided on the butt end side of the pipe panel, i.e. on the first end side or on the second end side. In addition or alternatively, according to a variant (not shown) of the invention with two additional panels, one additional panel may be provided on the non-abutting end side, i.e. the third end side or the fourth end side, and the abutting end side, i.e. the first end side or the second end side, respectively, or on both the first end side and the second end side, respectively.
Figure 3 shows a perspective view of the internal chamber of a mobile refrigerator formed by the butting of the roll-bond evaporators according to the first embodiment of the invention. The facing side of the roll-bond evaporator 1 is fixed by three rivets to form the interior of the mobile refrigerator, however, fig. 3 depicts the form of the facing fixing of the roll-bond evaporator only by a schematic illustration, and in fact no impressions or indentations of rivets are formed on the inner wall of the interior formed by the facing. Thus, as can be seen from figure 3, the inner wall of the inner chamber of a mobile refrigerator formed with a preferred roll-bond evaporator 1 according to the invention (i.e. the non-piping panel 8) is substantially flat and free of bulges
Furthermore, according to the utility model discloses a second aspect provides a remove refrigerator, should remove refrigerator has according to the utility model discloses a mutual butt joint of roll-bond evaporator 1 of first aspect formed inner chamber, the inner wall of inner chamber is level and smooth, does not have the arch basically to the surface has good metallic feel and aesthetic property. Preferably, the refrigerator according to the second aspect of the present invention is an in-vehicle refrigerator.
