Abstract: Disclosed are a highly corrosion-resistant aluminum alloy for a heat exchanger tube and a method for manufacturing a heat exchanger tube using the same. The highly corrosion-resistant aluminum alloy includes 0.05 to 0.5 wt % of iron, 0.05 to 0.2 wt % of silicon, 0.6 to 1.2 wt % of manganese, 0.15 to 0.45 wt % of copper, 0.05 to 0.3 wt % of at least one of zirconium and boron, and the remainder of aluminum and impurities. The aluminum alloy aluminum alloy for a heat exchanger tube improves corrosion resistance without affecting the physical properties other than corrosion resistance, through improvement in composition of the alloy, and ensures sufficient corrosion resistance without thermal arc spraying of zinc, resulting in a simple process, which leads to improvement in manufacturing efficiency and productivity of products.

Abstract: An automotive heat exchanger extrusion tube includes a tube body; and a coating layer formed by applying a coating liquid containing silicon powder to an outer surface of the tube body, wherein the coating layer is formed only on a portion of the outer surface of the tube body and extends along the longitudinal direction of the tube body.

Abstract: Disclosed is an apparatus for manufacturing an electrolytic metal foil, which includes an electrolytic cell containing electrolyte; an upper drum installed in an upper portion of the electrolytic cell to be rotatable and to which a negative potential is applied; a lower drum soaked in the electrolyte of the electrolytic cell and installed to be rotatable together with the upper drum; a cathode belt mounted around outer circumferences of the upper and lower drums to move along an endless track and electrically connected to the upper drum so that the negative potential is applied thereto; and an anode unit installed to form a space from a metal electroplating surface of the cathode belt soaked in the electrolytic cell so that a positive potential is applied thereto, the anode unit having a slit for supplying the electrolytic to the space. This apparatus may increase a production rate of electrolytic metal foils.

Abstract: An apparatus for manufacturing a heat exchanger tube includes an extruding means for extruding an aluminum preform in the shape of a tube; and a pair of compression rollers, each provided above and below the aluminum tube for compressing a central portion of the aluminum tube in the lengthwise direction of the aluminum tube, and having a disc-like shape. The present invention can process a heat exchanger tube without changing the shape of a die of the extruding means. As a result, excessive stress that may be applied to the die is prevented, and a heat exchanger tube is manufactured safely. And, an integrated two parallel-row tube with a connection portion according to the present invention provides simple assembly of a heat exchanger and a larger heat radiation area to increase a heat radiation efficiency.

Abstract: For flux coating of a heat exchanger tube made of aluminum, firstly, the heat exchanger tube is dipped in a storage tank containing a mixture of binder and solvent to coat the mixture on a surface of the heat exchanger tube, thereby forming a first coating layer on the surface of the heat exchanger tube. Then, flux powder is sprayed to the surface of the heat exchanger tube on which the first coating layer is formed, thereby forming a second coating layer. After that, a thickness of the heat exchanger tube on which the second coating layer is formed is controlled. Then, the thickness-controlled heat exchanger tube is heated to 150° C. or below so as to remove the solvent from the second coating layer.

Abstract: A thermistor of which resistance is changed depending on temperature and a secondary battery to which the thermistor is attached are disclosed. The thermistor is attached to an object via a lead which is made of different kinds of materials. The lead is configured so that a part of the lead to be united to the thermistor electrode is mainly made of the same material as the electrode and a part of the lead to be united to the object is mainly made of the same material as the surface of the object. Thus, the thermistor may be simply attached to the object only using the ultrasonic welding, thereby remarkably reducing junction inferiorities.
