Abstract: A bubble cycling heat exchanger comprises a sealing fluid loop, a heat absorbing source, a bubble generator, an expanding area for generating bubbles to be transferred to a fluid loop and a radiator. As one end of the seal loop is connected to the heat absorbing source, another end being connected to the radiator. The bubble generator is installed in the loop. Overheat will generate bubbles in the loop. As an unequilibrium occurs, the bubble will separate so that the fluid in the loop will flow to transfer heat, and thus heat is radiated from the radiator. As a result, the loop operating continuously until a heat equilibrium is achieved.

Abstract: A stacked-type heat dissipating apparatus of the present invention includes at least one layer of heat dissipating plate stacked upon a heat guiding plate. The heat dissipating plate has a plurality of strip-shaped projections formed therein to provide a separation space between at least one layer of heat dissipating plate and the heat guiding plate. Each of the strip-shaped projections having two ends respectively formed a first pierced edge in a punch press for providing an air guide channel. Whereby the present invention has a high stacking density at small volume integrally and to assemble easily, further to provide a large porosity, to reduce hydraulic resistance and hydraulic noise.

Abstract: A bubble cycling heat exchanger is disclosed. A closed fluid loop is in contact with a heat absorbing source through a heat conducting block; the loop has a bubble generator, an expanding area for generating bubbles is installed at loop; the loop is also formed with a guide region from which bubbles is easily separable and a radiator; a heat conducting block of the closed loop is connected to a heat absorbing source; since the overheat of the heat absorbing source will cause the loop to generate bubble; by an unequilibrium formed at the guide region of the loop, the bubbles will separate from the heat absorbing source so that the liquid in the loop flows for transferring heat so that heat is radiated by the fins or other elements of the radiator from the primary element of a computer at the heat absorbing source, the loop operates continuously until a heat equilibrium is achieved.
