Abstract: A novel housing for an electronic device is located in the passenger compartment of a vehicle. The housing is used to maintain the temperature of the electronic device within its operating temperature range. The housing includes air inlets and outlets through which the temperature-regulated air current from the air conditioning system of the vehicle passes. The temperature-regulated air currents from the air conditioning system that are used to maintain a comfortable temperature in the passenger compartment are also used to regulate the temperature of the electronic device. Thus, the housing allows the temperature of the electronic device to be regulated exclusively using the air current from the air conditioning system. The air duct from the air conditioning system can be connected directly to the housing or can end a distance from the housing so that the air current from the duct is directed to strike the outside of the housing.

Abstract: Method and apparatus for sealing an air vent in a switchgear cabinet provide a vent seal assembly having a vent seal cover and a set of linear guides on which the vent seal cover may be mounted. The vent seal cover and linear guides are housed within a casing attachable to an interior surface of the switchgear cabinet and directly over an air vent. Within the casing, the vent seal cover may slide freely along the linear guides toward the air vent, with no spring or other mechanical biasing mechanism to oppose the sliding of the cover. A catch on the casing releasably holds the vent seal cover to keep the air vent open during normal operating conditions. When an arc event occurs, pressure from the arc event knocks the vent seal cover free of the catch and propels it toward the air vent, quickly slamming the air vent shut.
