    Patent number: 6612365
    Abstract: A heating-element accommodating-box cooling apparatus includes: an indoor air passage 5 for fetching air in a heating-element accommodating box and returning it to the heating-element accommodating box; an outdoor air passage 9 for fetching outdoor air and exhausting the fetched outdoor air to the outside; a partition plate 10 provided so that both of the air passages become independent of each other; a fan unit 3 for conveying air in the outdoor air passage 9 and the indoor air passage 5; and a heat exchange element 4 disposed at a point of intersection between the two passages to exchange the sensible heat of the outdoor air and the indoor air, wherein the heating-element accommodating-box cooling apparatus is mounted exteriorly on a panel of the heating-element accommodating box. Consequently, it is possible to effect cooling of the heating-element accommodating box with energy saving, and the space for installation of the cooling apparatus in the box is not required.
