車両用電子機器における冷却構造と防塵構造との両立性検討

抄録

In order to let power electronics apparatus extend its life, it is necessary to keep the temperature of the apparatus constantly by some kind of cooling methods. Though the forced air-cooling by the fresh air introduction is the most efficient of all cooling methods, cooling performance decreases because dust included in the fresh air invade the apparatus and attach to the apparatus. Therefore, in this article, we report the result the best structure optimized by the simulation and the performance evaluation with the trial product.
