Abstract

Shielding liquid from electronic components may be accomplished by a variety of systems, devices, and techniques. A shielding device 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.

Claims

1. A system for shielding a fuel dispenser component from liquid, comprising:

a fuel dispenser; and

the fuel dispenser component comprising;

a substantially vertical channel mounted to the fuel dispenser component, the channel adapted to guide an airflow within the channel;

an airflow inlet arranged substantially horizontal at a first end of the channel;

a plurality of arrays of angled protrusions disposed within the channel, the angled protrusions substantially parallel in arrangement within each array, the angled protrusions within each array angularly offset in arrangement relative to the angled protrusions within adjacent arrays, the arrays of angled protrusions adapted to form a tortuous path for the airflow through the channel; and

a plurality of substantially vertical protrusions disposed within the channel, the vertical protrusions located between the airflow inlet and the plurality of arrays, the vertical protrusions adapted to substantially straighten the airflow within the channel.

2. The system of claim 1, the channel comprising a longitudinal dimension of approximately 8 inches.

3. The system of claim 1, further comprising a non-corrosive screen detachably mounted within the airflow inlet.

4. The system of claim 1, the angled protrusions within each array offset at approximately 90 degrees relative to the angled protrusions within adjacent arrays.

5. The system of claim 1, the plurality of arrays comprising at least four arrays of angled protrusions.

6. The system of claim 1, each array of angled protrusions comprising at least seven angled protrusions.

7. The system of claim 1 further comprising a fuel dispenser access panel, the access panel comprising at least a portion of the substantially vertical channel.

8. The system of claim 7, the fuel dispenser access panel comprising:

the airflow inlet;

one or more hinges adapted to attach the fuel dispenser access panel to the fuel dispenser; and

a locking mechanism.

9. The system of claim 7, wherein the fuel dispenser access panel is a currency acceptor access panel, the currency acceptor access panel comprising a currency inlet aperture.
