Abstract:
1. A bubble cycling heat exchanger, comprising at least one closed fluid loop having a liquid therein and being in thermal contact with a heat absorbing source through a heat conducting block, the loop having a bubble generator being a spiral wire embedded in the loop for generating bubbles in the liquid, and an externally mounted expanding area installed adjacent to and in fluid communication with the loop, the loop being formed with a guide region from which bubbles are easily separable and with a radiator, wherein responsive to overheating of the heat absorbing source, the bubble generator generates bubbles and by an unequilibrium formed at the guide region of the loop, the bubbles separate from the guide region so that the liquid in the loop flows therethrough for transferring heat from the heat absorbing source to the radiator, the loop operating continuously until a thermal equilibrium is achieved.
