  • Heat exchange structure for a heat source
    Patent number: 6148907
    Abstract: A heat exchange device includes a case-shaped cover directly contact on a heat source to exchange heat, an air-in tube having one end connected to the cover, a fan fixed on an outer wall of a case of an appliance having the heat source and connected to the air-in tube, and an air-out tube having one end connected to the cover and the other end extending out of the case of the appliance to outer air. Then the fan, the air-in tube, the cover and the air-out tube make up a heat exchange route, with cool outer air blown into the air-in tube by the fan, then flowing a round in the cover to flow out of the air-out tube so that hot air within the case of the appliance may be exhausted, not staying therein.
