    Abstract: The present invention discloses a cooling system with a passive heat dissipation structure, the cooling system includes plural heat conducting pipes, and a shielding tube included to surround the heat conducting pipes. The heat generated from a heat source placed below the cooling system heats the surrounding fluid (air) and turns it into heated fluid. The heated fluid is lower in density and is dissipated away through convection by the heat conducting pipes, leaves its original space to cooler fluid (at room temperature). The mixing of the heated fluid with the cooler fluid can be prevented by the heat conducting pipes, and the heat convection of the heat source by the cooler fluid is increased. With the implementation of the present invention, the benefits of easy implementing, easy to use, requiring no extra energy and saving costs are achieved, and the heat of the heat source is promptly dissipated away.

  • Publication number: 20140041842
    Abstract: A heat exchange chamber includes an inlet, an outlet and a plurality of walls defining a chamber interior. The inlet receives a heat exchange medium flowing in a first flow direction in an initial line of flow. Disposed within the chamber interior is a medium directing member, having an inclined surface, which diverts the medium from the initial flow direction so that it disperses within the chamber interior. Exposure to the contact surfaces provided by the chamber walls causes the medium to exchange heat with the chamber and the external environment. The medium exits the chamber, via the outlet, in the initial line of flow. The chambers are interconnected by tubes to form assemblies. Plural sets of chamber and tube assemblies are arranged between manifolds to provide a heat exchanger.
