Abstract: Maintaining an operational temperature range of a fuel dispenser component may be accomplished by a variety of systems, devices, and techniques. In one aspect, a fuel dispenser temperature maintenance system includes a centrifugal fan and an airflow separator. The centrifugal fan is detachably mounted to a fuel dispenser and adapted to circulate an airflow from an exterior to an interior of the fuel dispenser; separate the airflow into a conditioning airflow and an ejected airflow; and direct the conditioning airflow directly to a fuel dispenser component. The ejected airflow includes a plurality of particulates. The airflow separator includes a separator inlet adapted to receive the ejected airflow. The airflow separator is adapted to guide the ejected airflow from the separator inlet directly to an exterior of the fuel dispenser through an outlet channel, where the outlet channel is disposed between the airflow separator and the exterior of the fuel dispenser.

Abstract: Shielding liquid from electronic components may be accomplished by a variety of systems, devices, and techniques. A shielding may include a substantially vertical channel mounted to a fuel dispenser component; an airflow inlet; a plurality of arrays of angled protrusions; and a plurality of substantially vertical protrusions. The channel is adapted to guide an airflow. The plurality of arrays of angled protrusions are, disposed within the channel and are substantially parallel in arrangement within each array. The angled protrusions within each array are angularly offset in arrangement relative to the angled protrusions within adjacent arrays. The arrays of angled protrusions are adapted to form a tortuous path for the airflow through the channel. The plurality of substantially vertical protrusions are disposed within the channel and are located between the airflow inlet and the plurality of arrays. The vertical protrusions are adapted to substantially straighten the airflow within the channel.
