Definitions

• the present invention relates to an external wall made of carbon fiber, used in a cooled body and/or door, and the production method thereof.
• insulation material is placed between the inner lining and the external wall forming the body and/or the door, with the purpose of providing heat insulation between the internal of the compartment and the outer environment.
• polyurethane material is used as the insulation material, and this material is filled through a gap between the inner lining and the external wall.
• the external wall of the door is made of metal
• the inner lining is made of plastic material, and just like the body, insulation material is filled into the insulation volume between the inner lining and the outer wall by way of injection.
• the weight of the door which usually comprises metal sheet, reaches up to five kilograms.
• the external appearance of the door is obtained by brushed metal sheet, PET film coated metal sheet, various paint alternatives and similar applications.
• JP09303947 discloses applying solid epoxy layer and resin interlayer enabling homogeneous distribution of the insulation material, on the inner lining of the body contacting the insulation material.
• German patent application no. DE 102011082874 discloses using carbon fiber material on ovens and coolers.
• the aim of the present invention is to realize a cooler comprising a light-weight and durable external wall with high visual quality perception.
• the cooler realized to achieve the aim of the present invention and disclosed in the first claim and the dependent claims, comprises an external wall forming the frontal surface of a door, having a carbon fiber based outer surface, fiber based inner surface and a binding agent provided between the inner surface and the outer surface.
• the outer surface is carbon fiber, aramid or colored carbon fiber.
• the carbon fiber has a diameter of 5 pm.
• the inner surface is used in order to enhance the strength of the external wall.
• the binding agent used to fix to each other the inner surface and the outer surface is resin based.
• the binding agent comprises chemicals containing BMI, Cyanate, Epoxy, Phenolic, Polyester or various formulas.
• the external wall is produced as follows: the outer surface comprising carbon fiber is prepared by being cut suitably.
• the fiber based inner surface is prepared by being cut in a sheet form, and the surfaces are cured so as to have a binding agent in between.
• the inner surface and the outer surface joined by means of the binding agent are subjected to a single mold process and are subsequently subjected to multi-mold process.
• the external wall is arranged in accordance with the external appearance of the door, and the process is completed by sizing the wall.
• the external wall thus produced is mounted on a door and/or a body.
• the external wall is particularly used on doors.
• the inner and the outer surfaces and the binding agent are cured in a temperature range of l00°C to l80°C.
• the wall is molded by being vacuumed with a pressure of almost 1 bar.
• the wall in the double mold process, is subjected to press molding with pressures between 20, 40 or 80 bars.
• the weight of particularly the cooler door is reduced by almost 60%. Low-cost hinges resistant to lesser weights can thus be used.
• a composite structure is obtained, with higher chemical corrosion and abrasion values than stainless steel or sheet pieces produced by a metallic press.
• An external wall of high visual quality perception is obtained without subjecting the material to any painting, coating, cataphoresis, pressing and similar processes.
• carbon fiber, aramid fiber, natural fibers such as bamboo fiber, or silver fiber can be applied on a cooler door so as to enhance the visual quality perception.
• scratch resistance values (ISO 4586-2) are increased to the level of 2N.
• Figure 1 is a perspective view of a cooler.
• Figure 2 is a sectional view of an external wall.
• the cooler (1) comprises a body (2), a door (3) enabling access into the body (2), an internal wall forming the side of the cooler (1) facing its inner volume, and
• the outer surface (5) is carbon fiber, aramid or colored carbon fiber.
• the carbon fiber has a diameter of 5 pm.
• glass fiber, cellulose fiber, bamboo fiber or fiber forms of different materials are used as the inner surface (6).
• the inner surface (6) enables enhancing the strength of the external wall (4).
• the binding agent (7) used to fix to each other the inner surface (6) and the outer surface (5) is resin based.
• the binding agent (7) comprises chemicals containing BMI, Cyanate, Epoxy, Phenolic, Polyester or various formulas.
• the external wall (4) is produced as follows: the outer and the inner surfaces (5 and 6) are prepared by being cut suitably. They are joined so as to have a binding agent (7) in between, and cured. After this step, the inner surface and the outer surface (5 and 6) joined by means of the binding agent (7), are subjected to a single mold process and are subsequently subjected to multi-mold process. Then the external wall (4) is arranged in accordance with the desired external appearance, and the process is completed by sizing the wall (4).
• the external wall (4) thus produced is mounted on the door (3) and/or the body (2).
• the external wall (4) is particularly used on the door
• the inner and the outer surfaces (5 and 6) and the binding agent (7) are cured in a temperature range of l00°C to l80°C.
• the wall is molded by being vacuumed with a pressure of almost 1 bar.
• the wall in the double mold process, is subjected to press molding with pressures between 20, 40 or 80 bars.
• the weight of the cooler (1) door (3) is reduced by almost 60%.
• Low-cost hinges resistant to lesser weights can thus be used.
• a composite structure is obtained, with higher chemical corrosion and abrasion values than stainless steel or sheet pieces produced by a metallic press.
• an external wall (4) is obtained having a high visual quality perception without being subjected to any painting, coating, cataphoresis, pressing and similar processes.
