Discharge nozzles from said rotor cavity are provided for said fluid near the periphery of said rotor; said nozzles may be arranged to discharge said fluid either radially, backward or forward as desired; said nozzles being either converging or converging diverging in shape as required to attain highest possible exit velocity for said fluid.，下面是Compressor with cooling专利的具体信息内容。
1. A compressing centrifuge for compressing a fluid comprising: a. a casing for containing said fluid and for providing support for a rotor shaft and bearings; said casing having respective inlet and outlet ports for receiving said fluid to be compressed and for discharging the compressed fluid; b. a rotor shaft for power input needed to effect rotation of a rotor; said shaft being journalled for rotation in bearings supported in said casing; said first shaft having first and second longitudinally extending cooling fluid passageways for conveying a cooling fluid therethrough; c. a rotating centrifuge rotor for subjecting said fluid to a centrifugal force field; said centrifuge rotor being mounted on said shaft so as to rotate in unison wiTh said shaft; said centrifuge rotor having an internal space with a plurality of heat conductive internal vanes defining respective cavities within said primary rotor for transferring heat from a compressible fluid during centrifuge compression thereof and for ensuring that any fluid within said centrifuge rotor rotates with the same rotational speed as said centrifuge rotor; said centrifuge rotor being equipped with means for introducing the fluid to be compressed at the center of the centrifuge rotor and having suitable discharge opening adjacent the periphery for discharging the compressed said fluid; said discharge opening being smaller in cross sectional dimensions than the minimum cross sectional dimensions of the associated cavities upstream thereof for ensuring that the fluid within the respective cavities of the rotating primary rotor will be subjected to centrifugation and centrifugal compression for effecting at the periphery of the rotor and upstream of the discharge opening a compressed fluid having a second pressure that is higher than the pressure at the inlet to said centrifuge rotor; d. a cooling means disposed interiorly of said rotor so as to rotate in conjunction therewith; said cooling means comprising at least a peripherally disposed cooling passageway and respective radially extending passageways that are connected at their respective ends with said cooling passageway such that a cooling fluid can flow through said cooling means in heat exchange relationship with the compressed fluid in said rotor and back to said second passageway in said shaft for discharge of the heated cooling fluid; said cooling means having sufficient cooling surface to effect in conjunction with predetermined design conditions of inlet and outlet temperatures and flow rates of said cooling fluid substantially isothermal centrifuge compression of said fluid in said rotor; e. diffuser and fluid collecting section intermediate said rotor and said outlet port and communicating with both for converting a high velocity, cooled, compressed said fluid to a high pressure fluid upstream of said outlet port; f. a compressible first fluid being flowed through said inlet port, being substantially isothermally compressed within said rotor by being cooled within said rotor to a temperature less than the temperature would otherwise be if subjected to the same centrifuge compression without cooling, being discharged through said discharge opening at high velocity, having its pressure raised further in said diffuser and fluid collecting section and being passed out of said outlet port; and g. cooling fluid being flowed through said cooling means and said first and second cooling passageways in said shaft; whereby said fluid can be compressed to a predetermined pressure with a relatively low rotational speed for said rotor.
2. The compressing centrifuge of claim 1 wherein said casing is fitted so closely to the external walls of said rotor that centrifugal action on fluid particles will partially evacuate the space between said casing and said rotor walls to reduce the fluid friction and allow said rotor to rotate more freely for more efficient operation.
3. The compressing centrifuge of claim 1 wherein said discharge opening of said rotor comprises a plurality of discharge nozzles that are oriented to discharge the centrifugally compressed said fluid from said rotating rotor in the direction in which said rotor is rotating such that said predetermined pressure can be achieved with even lower said rotational speed.
4. The compressing centrifuge of claim 1 wherein said first fluid is air.
5. The compressing centrifuge of claim 1 wherein said cooling fluid is water.
6. A method of compressing a first gaseous fluid and simultaneously heating a second fluid comprising: a. subjecting said first fluid to a centrifugal force field via a centrifuge rotor having vanes defining cavities to ensure that the fluid attains the same rotational speed as said rotor, in a compressing centrifuge to compress the fluid to a first pressure that is higher at the periphery of said centrifuge rotor than at the entry thereto; b. cooling the compressed said fluid during its centrifuge compression to obtain substantially isothermal compression interiorly of said rotor by circulating said second fluid at an adjustable flow rate along the axis of rotation of said centrifuge rotor, radially outwardly and within said centrifuge rotor and adjacent the periphery of said centrifuge rotor in heat exchange relationship with the compressed said first fluid to heat said second fluid to a predetermined operational temperature commensurate with a predetermined resultant cooling of said first fluid during centrifuge compression; and passing the heated said second fluid radially inwardly to be discharged along the axis of rotation of said centrifuge rotor; c. passing said first fluid in its cooled, compressed state through discharge passageways that are smaller in cross sectional area than the minimum area of the respective associated cavities intermediate said vanes upstream of the discharge passageways to a lower second pressure and, thence, to a diffuser and fluid collecting section in which a large portion of the kinetic energy contained in the discharged fluid is converted to pressure to raise said pressure to a third pressure that is higher than said first pressure; and d. passing said fluid from said rotor to an outlet of said compressing centrifuge; the pressure of said fluid at said outlet of said compressing centrifuge being higher than at the inlet to said compressing centrifuge.
