  • Heat exchange and cooling systems
    Patent number: 8887525
    Abstract: A heat exchanger may be associated with a heat transfer system to promote flow of heat energy from a heat source to a multi-phase fluid. The heat exchanger may be associated with an expansion portion. The fluid may be a refrigerant to which nano-particles may be added. Embodiments of the present invention may be implemented in an air-conditioning system as well as a water heating system.

  • Cooling of heat intensive systems
    Patent number: 8820114
    Abstract: Disclosed herein is a cooling system that utilizes a supersonic cooling cycle. The cooling system includes accelerating a compressible working fluid, and may not require the use of a conventional mechanical pump. The cooling system accelerates the fluid to a velocity equal to or greater than the speed of sound in the compressible fluid selected to be used in the system. A phase change of the fluid due at least in part to a pressure differential cools a working fluid that may be utilized to transfer heat from a heat intensive system.

  • PRESSURE SHOCK-INDUCED COOLING CYCLE
    Publication number: 20140174113
    Abstract: A supersonic cooling system operates by pumping liquid. Because the supersonic cooling system pumps liquid, the compression system does not require the use of a condenser. The compression system utilizes a compression wave. An evaporator of the compression system operates in the critical flow regime where the pressure in an evaporator tube will remain almost constant and then ‘jump’ or ‘shock up’ to the ambient pressure.

  • FLUID FLOW CONTROL DEVICE
    Publication number: 20140096854
    Abstract: A fluid flow control device that controls a flow of fluid within the flow control device has a flow path to convey the fluid. A cross-sectional area of the flow path varies along the flow path. At least a portion of the length of the fluid flow control device includes an active surface capable of influencing the fluid flow through the flow path to cause vortical motion of the fluid within the fluid pathway.

  • Battery cooling
    Patent number: 8505322
    Abstract: A battery cooling system operates by pumping liquid through a cooling fluid circulation path. Because the battery cooling system pumps liquid, the compression system that generates the cooling power does not require the use of a condenser. The compression system utilizes a compression wave. An evaporator of the cooling system operates in the critical flow regime in which the pressure in an evaporator tube will remain almost constant and then ‘jump’ or ‘shock up’ to an increased pressure.
