Abstract
A bubble cycling heat exchanger system includes a closed fluid cycling loop containing a working fluid therein for removing heat from a heat source thermally coupled to a longitudinally extended heat-conducting block. The closed fluid cycling loop is contacted in proximity to the beat-conducting block with only one side portion thereof near the heat source for establishing a temperature difference and a density difference of the working fluid to aid in achieving a unidirectional flow therein.
Claims14
A bubble cycling heat exchanger system, comprising:
- a heat-conducting block thermally coupled to a heat source;
- and
- at least one closed fluid cycling loop containing a working fluid therein, and having a spiral tube defining a plurality of longitudinally arranged coils and a flow-returning tube with two opposing ends respectively connected to corresponding opposing ends of said spiral tube for generating a circulating flow, wherein said coils each have two side portions, one of the two side portions thereof in contact with the heat-conducting block.
A closed fluid cycling loop containing a working fluid therein for removing heat from a heat source thermally coupled to a longitudinally extended heat-conducting block, comprising:
- a spiral tube defining a plurality of longitudinally arranged coils, each of said coils having a left-half portion and a right-half portion of an asymmetric cross-sectional contour thereof, the spiral tube being adapted for contact with said heat source at an arbitrary location;
- and
- a flow-returning tube with two opposing ends respectively connected to corresponding opposing ends of said spiral tube for generating a circulating flow.
A closed fluid cycling loop containing a working fluid therein, comprising:
- a plurality of spiral tubes being interlaced together in proximity one to another and each defining a plurality of longitudinally arranged coils;
- and
- a plurality of flow-returning tubes each having two opposing ends respectively connected to corresponding opposing ends of each of said spiral tubes thereby to longitudinally pass through an inner perimeter of each of the coils each of said spiral tubes;
- wherein said coils each have a left-half portion and a right-half portion of an asymmetric cross-sectional contour thereof with respect to a heat source thermally coupled to a heat-conducting block for establishing a temperature difference and a density difference of the working fluid to aid in achieving a unidirectional flow therein.
