Reciprocating-Mechanism Driven Heat Loop
View pageUS Patent:
6684941, Feb 3, 2004
Filed:
Jun 4, 2002
Appl. No.:
10/163893
Inventors:
Yiding Cao - Miami FL, 33193
Mingcong Gao - Miami FL, 33172
Mingcong Gao - Miami FL, 33172
International Classification:
F28D 1500
US Classification:
16510425, 165272, 16510426
Abstract:
A heat transfer device which employs a reciprocating mechanism for driving liquid from the heat rejection section to the heat receiving section is disclosed. The heat transfer device is coined as the reciprocating-mechanism driven heat loop which comprises a hollow loop having an interior flow passage, an amount of heat-carrying fluid filled within the loop, and at least one reciprocating driver. The hollow loop has at least one heat receiving section, one heat rejection section, and one liquid reservoir. The reciprocating driver is integrated with the liquid reservoir and facilitates a reciprocating flow of the heat-carrying fluid within the loop, so that the liquid is supplied from the heat rejection section to the heat receiving section under both saturated and unsaturated conditions and a high heat transfer rate from the heat receiving section to the heat rejection section is achieved. A substantial temperature uniformity is also attained when the air is evacuated from the loop and the heat-carrying fluid hermetically sealed within the loop is under a substantially saturated condition. Additionally, many of the heat transfer limitations associated with a heat pipe or capillary pumped loop are essentially eliminated.
Waste Heat Recovery Means For Fuel Cell Power System
View pageUS Patent:
6926979, Aug 9, 2005
Filed:
Oct 15, 2002
Appl. No.:
10/270868
Inventors:
Yiding Cao - Miami FL, US
International Classification:
H01M010/50
US Classification:
429 12, 429 13, 429 22
Abstract:
A fuel cell power system includes at least a fuel cell stack, a cooling means which removes the waste heat generated within the fuel cell stack, a fuel reformer which reforms a hydrocarbon for the fuel supply to the fuel cell stack, and an energy recovery system, which includes an expansion valve for reducing the pressure of the feedstock to the energy recovery system, a heat exchanger for facilitating the heat transfer from the cooling means of the fuel cell stack to the feedstock of the energy recovery system, and at least a compressor for raising the pressure of the feedstock to a sufficiently high level and delivering the feedstock to the fuel reformer, thereby a substantially large portion of the waste heat is recovered and used to vaporize the feedstock. As a result, the fuel utilization of the fuel cell power system is significantly improved due to a reduced heat input to the fuel reformer, and the size of the radiator and the associated power consumption for dissipating the waste heat into the surroundings is substantially reduced.

Abstract:
This invention provides an internal combustion engine that has a substantially increased expansion ratio, a variable compression ratio, and subsequently a significantly improved thermal efficiency.

The engine comprises at least a piston and cylinder assembly including a piston reciprocatingly mounted within the cylinder space, and at least two combustion chambers associated with said cylinder, each said combustion chamber having a port leading to said cylinder space and a combustion-chamber valve, said valve opens and closes said port to establish or block the communication between said combustion chamber and cylinder space, wherein said internal combustion engine is adapted to operate on preferred cycles in accordance with load conditions to substantially increase the engine's expansion ratio or provide a variable compression ratio mechanism under part load conditions. For an engine having two combustion chambers associated with each cylinder, the expansion ratio or compression ratio may be nearly doubled. Additionally, a cold start mechanism particularly for an engine operating on alternative fuels, such as ethanol or methanol, and engine valves that are operationally suitable for the engine cycles in accordance with the present invention are disclosed.

Yiding Cao - Miami FL, US
International Classification:
F25D 9/00
F25B 9/00
F25B 9/00
US Classification:
62403, 62 6
Abstract:
This invention provides a refrigerator using a gaseous working fluid such as air and based upon the well-developed structure of reciprocating compressors or rotating engines. The invention combines the compression functionality of a compressor and the expansion functionality of a turbine in an air cycle machine into a single refrigeration unit having a simple mechanical structure, and provides a significantly increased heat removal time period before the expansion stroke to reduce the temperature of the working fluid under a substantially constant volume without increasing the number of strokes per discharge in a cycle. Moreover, the need of using a man-made chemical as the working fluid is eliminated.

Abstract:
This invention provides heat engines based on the structure of internal combustion engines and employs a gaseous working fluid without combustion. The heat engine comprises at least a piston and cylinder assembly and each cylinder has at least an associated heating chamber with a heat exchanger unit being disposed therewithin. The chamber may have at least a chamber valve to establish or block the flow of the gaseous working fluid between the heating chamber and cylinder space. The engine is adapted to operate on cycles that enable heat transfer from a heat source to the working fluid while being enclosed within the heating chamber and provides substantially increased heat transfer duration before the power stroke. Therefore the engine may produce sufficiently high power output with reasonably high thermal efficiency.

US Classification:
429/030000, 429/025000, 429/032000, 429/034000
Abstract:
A compact, lightweight direct methanol fuel cell unit includes a circular membrane electrode assembly (MEA) having a cathode, a proton exchange membrane (PEM), and an anode, an air flow duct on the cathode side of the MEA, an annular fuel reservoir on the anode side of the MEA which contains a mixture of methanol and water as fuel, a carbon dioxide (CO) relief valve communicating with the fuel reservoir, and a control unit. Due to the COrelease mechanism, the fuel cell is completely self-sustaining without the need for a mechanical auxiliary system. Additionally, the control unit improves the stability of the fuel cell power output and the catalysis activity of the MEA. Another embodiment of the present invention is a direct methanol fuel cell system which incorporates a number of MEAs and a fuel cell reservoir. All the cathodic electrical terminals of the MEAs are serially connected together while they are electronically communicating with the control unit. The anodic electrical terminals similarly communicate electronically with the control unit. Higher power and voltage are thus attained while maintaining a compact size of the fuel cell system.
