Abstract:
A vacuum heat insulating material having an improved structure to prevent the heat bridge phenomenon while improving the durability thereof, and a refrigerator having the same, the vacuum heat insulating material including a core material in a vacuum state, a sealing layer surrounding the core material, an inner layer covering the sealing layer, and having a first side and a second side connected to the first side, a protective layer located at an outside of the inner layer, a first blocking layer having at least one portion located between the first side of the inner layer and the protective layer, and a second blocking layer having at least one portion located between the second side of the inner layer and the protective layer.
Abstract:
Disclosed are a vacuum suction nozzle for improving vacuum suction performance and a vacuum suction apparatus including the same. The nozzle includes blade portions extending from both sides thereof so as to reduce a gap occurring between the nozzle and an outer skin material for a vacuum insulation panel (VIP) or other vacuum wrapping paper when the outer skin material or vacuum wrapping paper is sealed, thereby minimizing the occurrence of a leak and thus enabling efficient vacuum suction. Further, the nozzle achieves efficient vacuum suctioning by ensuring a suction channel inside the vacuum insulation panel (VIP) or other vacuum wrapping paper through a protrusion extending to the front of the nozzle.
Abstract:
Provided herein is a gas barrier film having excellent flexibility and an excellent gas barrier characteristic at the same time and a refrigerator having the same. Provided herein is a method of manufacturing a gas barrier film. The gas barrier film includes an organic-inorganic mixed layer on which a first organic-inorganic hybrid layer including a first organic part and a first inorganic part and an aluminum oxide layer are laminated. The gas barrier film also includes a second organic-inorganic hybrid layer including a second organic part and a second inorganic part. The gas barrier film further includes a substrate on which the organic-inorganic mixed layer and the second organic-inorganic hybrid layer are laminated.
Abstract:
A heat exchanger includes a refrigerant pipe through which a refrigerant flows, and a plurality of fins coupled to an outer circumference surface of the refrigerant pipe, wherein each fin includes a first region disposed upstream with respect to an air flow direction, and a second region which forms a boundary with the first region and is disposed downstream with respect to the air flow direction, and wherein the first region and the second region have different surface energies in order to prevent formation of condensation water on the fin.
Abstract:
Disclosed herein are a vacuum insulation panel having an improved structure which may improve durability by minimizing a folding process, and a refrigerator including the same.The vacuum insulation panel includes a core material, a first outer skin material that is arranged to form an outer surface of the core material, a second outer skin material that has a gap and forms the other outer surface of the core material, and is disposed to face the first outer skin material, and a third outer skin material that is provided to connect the first outer skin material and the second outer skin material and to be variable in accordance with the gap.
Abstract:
A vacuum insulation panel includes a core material, a first sheathing material disposed outside the core material, and a second sheathing material having different thermal conductivity from the first sheathing material, the second sheathing material being coupled to the first sheathing material to form a space to receive the core material.
Abstract:
Disclosed is a refrigerator including a vacuum insulation panel. The vacuum insulation panel includes a core material, a covering material disposed outside the core material to form an accommodation space in which the core material is accommodated and a first adsorbent disposed in the accommodation space to be activated at a temperature higher than room temperature and to remove at least one of gases and water present in the accommodation space.
