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.

First claim

What is claimed is:

1. A currency acceptor for use in a fuel dispenser, comprising:
a currency acceptor housing having an access panel coupled thereto for providing access to the housing, and having an opening for receiving payment; and
a temperature maintenance system disposed within the currency acceptor housing and including
a channel that is substantially vertical,
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 within each array being substantially parallel in arrangement, 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 , wherein the plurality of arrays of angled protrusions and the plurality of substantially vertical protrusions are mounted on the access panel.

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

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

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

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

7. The system of claim 1 , further comprising a currency inlet aperture in the access panel.

8. The system of claim 1 , wherein the access panel is coupled to the housing by one or more hinges, and wherein the access panel includes a locking mechanism.
