Abstract:
A heat exchanger having an improved structure in which heat-exchanging efficiency can be improved includes: a refrigerant pipe through which a refrigerant flows; and a plurality of fins that are coupled to an outer circumferential surface of the refrigerant pipe, wherein the plurality of fins include: a first region formed downstream in a direction in which air flows; and a second region formed upstream in the direction in which air flows, and at least one coating layer is formed in the first region and the second region, and thicknesses of the first region and the second region are different from each other.
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:
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:
An antifreeze member includes a metal substrate, and a first coating layer including a recombinant antifreeze protein in which a metal-binding protein is conjugated to a performance-enhancing reformed antifreeze protein, and being bonded to the metal substrate via the metal-binding protein.
