摘要

The housing for electrical equipment has its upper and lower faces and formed by two box-shape sections. Each section is made from two parallel metal plates separated by metal extrusions to which the plates are rivetted at their edges. The plates have venting apertures that allow cooling air to flow through the sections and through the housing. Side plates are joined at their edges to the extrusions of respective box-like sections. The housing has two compartments which are screened from one another by a dividing wall. One compartment has rails by which electric circuit cards are mounted vertically in the compartment such that they can be readily removed through a front aperture that is closed by a removable cover plate.
