This is a model of an electronic enclosure which contains microwave components on one side of a central air cooled coldplate and printed circuit boards on the other side. A fan on the left side draws ambient are through the central finned heat exchanger. The equipment is outside so in addition to the electronics power dissipation, there is a solar heat load on the top of the box. The thermal interface of the removable top cover is included, wedgelock resistances at the PCBs as well as radiation and convection to the ambient.
