Storage box for electronic control units

摘要

The storage box employs an inner box surrounded by an outer box. The inner box houses an electronic control unit. Between the two boxes is a space in which air circulates to cool the electronic control unit. A hole in the inner box is sealed with a filter that is impervious to water but allows air to freely pass. Thus, the electronic control unit is cooled without being damaged by water and dirt in the cooling air.
