Abstract: A heat exchanger includes a metal base defining a heat exchange channel for flowing at least one of a refrigerant and a coolant therein, and a coating layer coated at least a part of an outer surface of the metal base. The coating layer includes sol particles and an antibacterial material, where the sol particles include silica. The antibacterial material includes a rare earth element oxide. By combining the antibacterial agent containing the rare earth element oxide with sol, the advantages of each component can be fully utilized. On the one hand, it is easier to attach the antibacterial material via the sol, and on the other hand a surface of the metal base of the heat exchanger can have a good antibacterial and mold-inhibiting effects, which is beneficial to cost reduction.

Abstract: The present invention provides a method and system of material identification using binocular steroscopic and multi-energy transmission image. With the method, any obstacle that dominates the ray absorption can be peeled off from the objects that overlap in the direction of a ray beam. The object that is unobvious due to a relatively small amount of ray absorption will thus stand out, and the material property of the object, such as organic, mixture, metal and the like can be identified. This method lays a fundament for automatic identification of harmful objects, such as explosive, drugs, etc., concealed in a freight container.
