Description
- This invention relates to a fluid machine, specifically a fluid machine suited to be incorporated in a Rankin cycle which recovers and utilizes waste heat from a vehicle engine.
- As a fluid machine of this type, there is known a pump-linked expansion machine comprising a pump mechanism incorporated in a Rankin cycle to force a refrigerant as a working fluid to circulate in the Rankin cycle to recover waste heat from a vehicle engine, for example, and an expansion mechanism for producing rotary drive power by expansion of the refrigerant having been forced out by the pump mechanism and then superheated, the pump mechanism and the expansion mechanism being linked by a shared drive shaft to form a unit (see
patent document 1, for, example). - In this prior art, an expansion mechanism exit passage and a pump mechanism exit passage are arranged such that a part of the former extends close to a part of the latter to allow transfer of heat from the refrigerant flowing in the expansion mechanism exit passage to the refrigerant flowing in the pump mechanism exit passage, thereby increasing the amount of heat added to the refrigerant in the Rankine cycle, and thus, increasing the efficiency of the Rankine cycle.
- Patent document 1: Japanese patent application preliminary publication No. 2006-266238
- The above prior art however gives no special consideration to make the fluid machine compact and reduce the production costs. Further, there is room for further increase in the amount of heat added to the refrigerant. The present invention has been made in consideration of such problems. An object of the present invention is to provide a fluid machine which can be compact and produced at reduced costs and which can further increase the amount of heat added to the refrigerant circulating in the Rankine cycle, and thus, greatly increase the efficiency of the Rankine cycle in which the fluid machine is incorporated.
- In order to achieve the above object, the present invention provides a fluid machine comprising a pump mechanism incorporated in a Rankine cycle to force a working fluid to circulate in the Rankin cycle to recover waste heat from a heat source, and an expansion machine for producing rotary drive power by expansion of the working fluid having been forced out by the pump mechanism and then superheated, the pump mechanism and the expansion mechanism being linked by a shared drive shaft, wherein a pump mechanism exit section through which the refrigerant flows out of the pump mechanism and an expansion mechanism exit section through which the refrigerant flows out of the expansion mechanism are open outward in the same direction.
- In order to achieve the above object, the present invention may further comprise an exit port member connected to both the pump mechanism exit section and the expansion mechanism exit section.
- In order to achieve the above object, the present invention may be arranged such that the exit port member has a pump mechanism exit passage and an expansion mechanism exit passage extending close to each other with a partition with a specified thermal conductivity interposed between, the pump mechanism exit passage and the expansion mechanism exit passage being connected to the pump mechanism exist section and the expansion mechanism exit section, respectively.
- In order to achieve the above object, the present invention may be arranged such that the pump mechanism exit passage and the expansion mechanism exit passage of the exit port member form a double pipe configuration functioning as an internal heat exchanger.
- As stated above, in the fluid machine according to the present invention, a pump mechanism exit section through which the refrigerant flows out of the pump mechanism and an expansion mechanism exit section through which the refrigerant flows out of the expansion mechanism are open outward in the same direction. This facilitates connection of the pump mechanism exit section and the expansion mechanism exit section to the Rankine cycle circulation path and allows the fluid machine to have a compact configuration as compared with the case where these exit sections are at different locations. Further, this allows the fluid machine to be composed of a reduced number of components, and thus produced at reduced costs.
- Further, the present invention may comprise an exit port member connected to both the pump mechanism exit section and the expansion mechanism exit section. Such exit port member allows the fluid machine to have an integrated configuration of the pump mechanism exit section and the expansion mechanism exit section, which enables a further compact configuration of the fluid machine, and thus, a further reduction in the production costs.
- Further, the present invention may be arranged such that the exit port member has a pump mechanism exit passage and an expansion mechanism exit passage extending close to each other with a partition with a specified thermal conductivity interposed between, the pump mechanism exit passage and the expansion mechanism exit passage being connected to the pump mechanism exist section and the expansion mechanism exit section, respectively. In this case, the exit port member allows transfer of heat from the refrigerant flowing in the expansion mechanism exit passage to the refrigerant flowing in the pump mechanism exist passage, and thus, can function as an internal heat exchanger in the Rankine cycle. This can increase the amount of heat added to the refrigerant circulating in the Rankine cycle, and thus, greatly increase the efficiency of the Rankine cycle in which the fluid machine is incorporated.
- Further, the pump mechanism exit passage and the expansion mechanism exit passage of the exit port member may form a double pipe configuration functioning as an internal heat exchanger. This allows further efficient transfer of heat from the refrigerant flowing in the expansion mechanism exit passage to the refrigerant flowing in the pump mechanism exit passage, and thus, further increase of the efficiency of the Rankine cycle in which the fluid machine is incorporated.

- An embodiment of the present invention will be described on the basis of the drawings.
FIG. 1 schematically shows a wasteheat utilization device 2 in which afluid machine 1, an embodiment of the present invention, is incorporated. The wasteheat utilization device 2 is mounted on a vehicle, for example, and comprises an electricpower extraction circuit 4, anair conditioning circuit 20, a cooling water circuit 30, and a Rankine circuit (Rankine cycle) 40. The electricpower extraction circuit 4 is an electric circuit for converting rotary drive power, produced by thevehicle engine 6, to electric power and extracting the electric power. The rotary drive power produced by theengine 6 is transmitted from anengine 6side pulley 8 to abelt 12, then to an electricpower recovery circuit 4side pulley 10, and thus, to analternator 14. Thealternator 14 converts the rotary drive power to electric power, and the electricpower extraction circuit 4 extracts the electric power. The electric power extracted by the electricpower extraction circuit 4 is used as electric drive power for a variety of electrical devices mounted on the vehicle, for example. - The
air conditioning circuit 20 forms a closed loop with acompressor 24, an air-conditioning condenser, a gas-liquid separator, an expansion valve, an air-conditioning evaporator, etc. disposed serially in arefrigerant circulation path 22, in the direction of circulation of a refrigerant as a working fluid. The devices disposed in the refrigerant circulation path, except for the compressor, are omitted in the diagram. The air conditioning circuit air-conditions, for example a vehicle interior by supplying the vehicle interior with air having passed through the air-conditioning evaporator. Thecompressor 24 is driven by the rotary drive power produced by theengine 6 and transmitted to apulley 26 by thebelt 12, and compresses the refrigerant having evaporated in the air-conditioning evaporator, and thus, converts it into superheated vapor. The refrigerant discharged from thecompressor 24 is condensed into a liquid in the air-conditioning condenser, and after passing through the gas-liquid separator, the liquid refrigerant is routed to the expansion valve. The refrigerant is expanded by passing through the expansion valve, and then flows to the air conditioning evaporator. - The cooling water circuit 30 forms a closed loop with a Rankine
evaporator 34, a radiator, a thermostat, a water pump, etc. disposed serially in a coolingwater circulation path 32 extending from theengine 6, in the direction of circulation of cooling water. The devices disposed in the cooling water circulation path, except for the Rankine evaporator, are omitted in the diagram. The cooling water circuit cools theengine 6. - The Rankine
circuit 40 forms a closed loop with the aforementioned Rankineevaporator 34, afluid machine 1, a -
Rankine condenser 44, etc. disposed serially in arefrigerant circulation path 42, in the direction of circulation of a refrigerant as a working fluid. The Rankinge circuit recovers waste heat from theengine 6 by means of the cooling water circulating in the cooling water circuit 30. - Here, the
fluid machine 1 is a pump-linked expansion machine comprising apump mechanism 46 for forcing the refrigerant to circulate and anexpansion mechanism 48 for producing rotary drive power by expansion of the refrigerant having been forced out by thepump mechanism 46 and then superheated in theRankine evaporator 34, the pump mechanism and the expansion mechanism being linked by a shareddrive shaft 50. The fluid machine assists rotary drive of theengine 6 by means of apulley 52 of thefluid machine 1 and theaforementioned belt 12. - The refrigerant having passed through the
expansion mechanism 48 and left thefluid machine 1 is condensed to a liquid in theRankine condenser 44, and the liquid refrigerant is again drawn in and forced out by thepump mechanism 46 of thefluid machine 1, thus leaving thefluid machine 1 toward theRankine evaporator 34. -
FIG. 2 is a vertical cross-sectional view of thefluid machine 1 as an embodiment of the present invention. To thedrive shaft 50 side of thepulley 52, thefluid machine 1 has aclutch mechanism 54 for appropriately transmitting the rotary drive power produced by theexpansion mechanism 48 from thedrive shaft 50 to thepulley 52, and thus, to theengine 6. Thepump mechanism 46 is driven together by the rotary drive power produced by theexpansion mechanism 48. Thepump mechanism 46 is a rotary pump driven by thedrive shaft 50 to rotate, and arranged in afront casing 56, between theexpansion mechanism 48 and theclutch mechanism 54. - The
expansion mechanism 48 is ascroll unit 60 arranged in arear casing 58. Thescroll unit 60 comprises a fixedscroll 62 and amovable scroll 64 orbiting relative to the fixedscroll 62. Themovable scroll 64 has aboss portion 66 on the rear side, or side remote from the fixedscroll 62, and aneccentric bush 68 is inserted in thebush portion 66. Acrank pin 70 is inserted in theeccentric bush 68. Thecrank pin 70 is joined to thescroll unit 60 side end of thedrive shaft 50 at an eccentric position, so that themovable scroll 64 can orbit without rotating. - The
clutch mechanism 54 has aclutch coil 72 arranged inside thepulley 52. When a current is supplied to theclutch coil 72, aclutch plate 74 contacts thepulley 52, so that the rotary drive power can be appropriately transmitted from thedrive shaft 50 to theengine 6. - In the present embodiment, the refrigerant having passed through the
pump mechanism 46 leaves thefluid machine 1 through a pumpmechanism exit section 46 a, while the refrigerant having passed through theexpansion mechanism 48 leaves thefluid machine 1 through an expansionmechanism exit section 46 a. - The
exit sections pump mechanism 46. They are open to outside thefluid machine 1, in the same direction, and connected to oneexit port member 76. Theexit port member 76 is fixed to the front casing by abolt 78. The exit port member has a pumpmechanism exit passage 76 a and an expansionmechanism exit passage 76 b extending parallel and close to each other, which are connected to the pumpmechanism exit portion 46 a and the expansionmechanism exit portion 48 a, respectively. Theexit passages partition 76 c which is made of a material higher in thermal conductivity than at least the materials of the other parts of theexit port member 76. - As stated above, in the present embodiment, the pump
mechanism exit section 46 a and the expansionmechanism exit section 48 a are open to outside thefluid machine 1, in the same direction, which facilitates connection of theexit sections circulation path 42 of theRankine circuit 40, and allows thefluid machine 1 to have a compact configuration as compared with the case where theexit sections fluid machine 1 to be composed of a reduced number of components, and thus produced at reduced costs. - Further, the use of the
exit port member 76 allows thefluid machine 1 to have an integrated configuration of theexit sections fluid machine 1, and thus, a further reduction in the production costs. - Furthermore, the
exit port member 76 having the pump mechanism exit passage 67 a and the expansionmechanism exit passage 76 b separated from each other by thepartition 76 c of a material with a high thermal conductivity and extending parallel and close to each other can function as an internal heat exchanger in theRankine circuit 40. Specifically, theexit port member 76 can preheat the refrigerant before its entering theRankine evaporator 34, by transfer of heat from the refrigerant flowing in the expansionmechanism exit passage 76 b to the refrigerant flowing in the pumpmechanism exit passage 76 a. This increases the amount of heat added to the refrigerant circulating in theRankin circuit 40, and thus, greatly increases the efficiency of theRankine circuit 40 in which thefluid machine 1 is incorporated. - In the above, one embodiment of the present invention has been described. The present invention is however not limited to the described embodiment, but can be modified in various ways without departing from the scope and spirit thereof.
- For example, the
exit port member 76 may be modified like a variant shown inFIG. 3 , in which theexit passages internal heat exchanger 80. This configuration allows more efficient heat transfer from the refrigerant flowing in the expansionmechanism exit passage 76 b to the refrigerant flowing in the pumpmechanism exit passage 76 a, and thus, further increase of the efficiency of theRankine circuit 40 in which thefluid machine 1 is incorporated. - The present invention allows a fluid machine to have a compact configuration and be produced at reduced costs, and can further increase the amount of heat added to the refrigerant circulating in the Rankine cycle and thus increase the efficiency of the Rankine cycle in which the fluid machine is incorporated. Thus, the present invention is applicable to fluid machines suited to be incorporated in the Rankine cycle which recovers and utilizes waste heat from a vehicle engine.
