Abstract
Among aluminum heat exchangers used for automotive air conditioning, the evaporator is located in the instrument panel. We have developed a new evaporator by: 1) improving the heat transfer performance through use of thinner tubes and fins; 2) establishing technologies for improving corrosion resistance and enabling reduction in wall thickness (development of highly corrosion-resistant material and control of Zn diffusion by shortening brazing time); and 3) improving refrigerant distribution in the tanks. The new evaporator is equivalent to our conventional MS Evaporator (of Multi-Tank Super-Slim Structure)(1) in cooling performance and corrosion resistance, while being significantly thinner (35% reduction) and lighter in weight (40% reduction).
