Abstract: The present invention relates to an electrode assembly and a secondary battery with the same, more particularly to the electrode assembly which includes an anode plate, a cathode plate, and a separator disposed between the anode plate and the cathode plate, wherein the separator includes a ceramic separator including a ceramic filler which is formed by mixing two groups of particles of the same material, but with a different diameter. The particles with the comparatively smaller diameter are disposed between the particles with the comparatively greater diameter.

Abstract: Provided is a water-cooled condenser of which the size is reduced by a simple structure and the cooling efficiency is improved, in which a main heat-dissipating unit where a coolant discharged from a compressor exchanges heat with cooling water and a supercooling core unit where a coolant discharged from a receiver drier exchanges heat with cooling water have separate cooling circuits and are integrated in one unit, a second cooling water inflow pipe, which allows the cooling water to flow into the supercooling core unit, diverges from a first cooling water inflow pipe that allows the cooling water to flow into the main heat-dissipating unit, and the cooling water flowing in the supercooling core unit is discharged with the cooling water in the main heat-dissipating unit, through an internal connecting line.

Abstract: A jelly roll electrode assembly, including a ceramic separator instead of a film separator and a secondary battery using the assembly, can be easily wound by forming a long non-coating portion of plate instead of the film separator to prevent cross-winding of the electrode assembly and the mandrel due to a friction by separating the wound electrode assembly from the mandrel, and to improve reliability.

Abstract: A heat exchanger tube and a heat exchanger that uses the heat exchanger tube. The heat exchanger tube is provided with a generally flat body has a plurality of refrigerant passages that pass through the interior of the flat body in the length direction thereof. The tube includes refrigerant passages which are provided with a plurality of inside passages, each of which has a first curved portion that is made by changing a predetermined curve over at least a time or more to form a curve changing point protruding in the width direction of the body. A second curved portion is formed opposite to the first curved portion and is connected slowly to the first curved portion to thereby form a curve closed face. A pair of outside passages is disposed on the outermost both ends of the plurality of inside passages.

Abstract: The gas-liquid separating condenser of the present invention can enhance the sub-cooling rate in the pre-sub-cooling section as well as in the total sections. Moreover, the present invention can have designs according to calculated conditional expressions of relative dimensional ratios of the sections in condensation of refrigerant to realize the optimum condensing efficiency regardless of the overall size of the gas-liquid separating condenser.

Abstract: Disclosed is a refrigeration cycle and a method for determining a capacity of a receiver of a refrigeration cycle. According to the present invention, the capacity of the receiver can be determined according to the variations of the paths of the condenser, which provides an ability of fully coping with the variations of the cooling load. When the method for determining the capacity of the receiver according to the present invention is applied in the condenser integrated with the receiver, it is possible that an optimal capacity where no brazing failure occurs is obtained, which means the optimal capacity for the receiver can be easily determined.
