1. An electronics cabinet comprising:
- an enclosure having;
a bottom surface;
a top surface having an opening formed through the top surface;
a front side wall connected to the bottom and top surfaces;
a back side wall connected to the bottom and top surfaces;
a first interior side wall connected to the front and back side walls, the first interior side wall being substantially vertical; and
a second interior side wall connected to the front and back side walls, the second interior side wall being substantially vertical;
a first exterior side wall connected to the front and back side walls to form a first air channel between the first interior and first exterior side walls;
a second exterior side wall connected to the front and back side walls to form a second air channel between the second interior and second exterior side walls;
a heat exchanger, a portion of the heat exchanger to extend through the opening in the top surface, the heat exchanger having;
a corrugated air-flow structure having a plurality of first corrugated openings and a plurality of second corrugated openings,a plate having a first external opening, and a spaced apart second external opening that contacts the corrugated air-flow structure so that the first and second external openings expose the plurality of first corrugated openings, anda plate having a first internal opening, a spaced-apart second internal opening, and a spaced-apart third internal opening that contacts the corrugated air-flow structure so that the first, second, and third internal openings expose the plurality of second corrugated openings, the first internal opening lying between the second and third internal openings,a fan to force air to flow up the first air channel, through the heat exchanger, and down the second air channel; and
a top cover that contacts the top surface, and covers the heat exchanger and the fan,an external air flowing up the first channel flows into the first external opening of the heat exchanger, through the first corrugated openings in the corrugated air-flow structure, and out the second external opening of the heat exchanger, an internal air flowing into the first internal opening flows through the plurality of second corrugated openings, and out through the second and third internal openings.

Abstract
A cabinet which utilizes an air-to-air heat exchanger to remove heat generated from within the cabinet prevents water and dust from entering the air-to-air heat exchanger by forcing cooler external air up along a first side wall, through the air-to-air heat exchanger, and down along a second side wall.
