Abstract

To develop an evaporator which is located in the instrument panel along with aluminum heat exchangers used for car air conditioners, we 1) upgraded heat transmission performance by using extremely thin tubes and fins, 2) established a thin, highly corrosion resistant plate material (and controlled zinc diffusion by minimizing the brazing time), 3) improved refrigerant distribution in the tank portions, and 4) adopted countermeasures to offset degraded water drainage performance due to the use of extremely thin fins. We succeeded in drastically reducing the body size (by 35 percent) and reducing the weight, by 40 percent, from the previous MS(Multi-tank super slim) evaporators currently produced by DENSO CORPORATION, while maintaining equivalent cooling performance and corrosion resistance.
