Conventionally, an apparatus for adjusting the temperature of a fluid such as a liquid is known. In a typical example, the device facilitates heat dissipation from the liquid and cools the liquid. However, such a device was not without its limitations.

  Conventionally, when it is required for some reason to cool a liquid, a refrigeration apparatus is used to cool the liquid. In an example of a conventional refrigeration apparatus, it is necessary to use an external power source or supply of external power such as electric power in order to drive a compressor of a refrigeration apparatus that circulates a refrigerant such as R-132. In another example of a conventional refrigeration system, the compressor is mechanically driven instead of electrical. In such a mechanical drive device, a belt mechanism or a gear mechanism is used to transmit power from the power shaft of the internal combustion engine to the compressor.

  The present invention provides a new heat transport device. The heat transport device includes a heat exchanger that adjusts at least the temperature of the fluid. The heat exchanger causes the primary fluid and the secondary fluid to exchange heat to dissipate heat from the primary fluid to the secondary fluid, thereby reducing the temperature of the primary fluid.

For example, the coupling device can include an internal drive member and an external facing member disposed to face the internal drive member. Furthermore, a rotational force can be transmitted by providing a magnet on at least one of the internal drive member and the external drive member and providing a magnetic body on the other, or providing a magnet on both. The device that generates the flow of the secondary fluid by the transmitted rotational force can be provided by a driven impeller that can also be called a blower.

  In one embodiment, the heat exchanger can be arranged to receive a primary fluid that has flowed out of the power converter. In other aspects, the power converter can be arranged to receive the primary fluid that has exited the heat exchanger. The heat exchanger can be arranged in the flow of the secondary fluid flowing out of the power converter, that is, downstream of the power converter. In another aspect, the heat exchanger can be placed in the flow of secondary fluid that is drawn towards the power converter, i.e. upstream of the power converter. In an exemplary embodiment, the primary fluid is a liquid such as fuel and the secondary fluid is a gas such as air.

  An apparatus for carrying heat may employ a heat exchanger with a heat exchanger inlet that receives fluid into the heat exchanger and a heat exchanger outlet that draws fluid from the heat exchanger. An apparatus for carrying heat employs a power converter comprising a fluid inlet for a drive impeller, a plurality of internal impeller plates that receive fluid from the fluid inlet, and a rotatable drive impeller member. Can do. Furthermore, the inner blade is mounted on a drive impeller member with a plurality of drive magnets. A driven impeller member with a plurality of driven magnets can include a plurality of external blades attached thereto. The heat exchanger is attached to the power converter so that fluid can be transferred. The fluid drives the inner vane and flows through the heat exchanger.

It is sectional drawing of the power converter device of FIG. FIG. 3 is a front view of a heat exchanger showing a fluid path through the heat exchanger. It is a side view of a heat exchanger.

  A plurality of modes for carrying out the present invention will be described below with reference to the drawings. In each embodiment, parts corresponding to the matters described in the preceding embodiment may be denoted by the same reference numerals, and redundant description may be omitted. When only a part of the configuration is described in each mode, the other modes described above can be applied to the other parts of the configuration.

  The drawings described herein are only for illustrating selected embodiments and do not represent all practical possibilities. The drawings described herein are not intended to limit the scope of the present invention. Corresponding reference characters indicate corresponding parts throughout the several views.

  A plurality of embodiments of the present invention will be described in more detail with reference to FIGS. First, in FIG. 1, the vehicle 10 includes an engine 12 mounted in an engine room 14. The engine 12 may be a gasoline engine or a diesel engine. The engine 12 is operated using gasoline or diesel fuel corresponding to the type of engine as fuel. The fuel is stored in the fuel tank 16 and is pumped up through the fuel supply path 18 by the fuel pump 20 mounted in the fuel pump module 22.

  In FIG. 2, the fuel supply system 24 shows components for supplying fuel to the engine 12 and returning fuel from the engine 12. The disclosure relating to the present invention is applicable to an engine using gasoline fuel, light oil (diesel) fuel, and kerosene fuel, but an engine using light oil fuel is used in the following description. Further, the disclosure relating to the present invention is applicable to non-fuel utilizing devices as will be described throughout the following description. Specifically, the disclosure relating to the present invention can be applied for the cooling of various fluids including non-fuel fluids.

  The fuel pump 20 in the fuel pump module 22 pumps liquid fuel such as light oil from the fuel tank 16 through the fuel supply path 18 and supplies it to the fuel injection pump 26. Such a fuel supply flow is indicated by an arrow 27. The fuel injection pump 26 pressurizes the fuel to the required fuel pressure in preparation for injecting pressurized fuel into the combustion chamber of the engine 12 for combustion.

  When the engine 12 is operating, the fuel pump 20 may be operated at a speed that exceeds the speed required to pump and supply the maximum amount of fuel required by the engine 12. Accordingly, a fuel return path 28 is provided as a part of the fuel supply system 24 in order to return unused surplus fuel to the fuel tank 16. More specifically, the fuel return path 28 returns unburned fuel from the fuel injection pump 26 to the fuel tank 16 as indicated by arrow 30.

  More specifically, the fuel return path 28 is divided into a heat exchanger front path 32 and a heat exchanger rear path 34. The fuel return path 28 is divided into the above two paths by the heat exchanger 36 with a power converter. The heat exchanger with a power converter 36 may be anywhere in the fuel return path 28. The heat exchanger with a power converter 36 is provided between the heat exchanger front path 32 and the heat exchanger rear path 34. As indicated by the arrow 30, the heat exchanger front path 32 supplies fuel to the heat exchanger with power converter 36. As indicated by the arrow 38, the post-heat exchanger path 34 supplies fuel to the fuel tank 16 from the heat exchanger 36 with a power converter.

  Based on FIG. 3 and FIG. 4, the heat exchanger 36 with a power converter device which concerns on 1st Embodiment is demonstrated. In the description of the heat exchanger with a power converter 36, liquid fuel is described as the primary fluid, but liquid that is not fuel can also be used as the primary fluid. The heat exchanger with a power converter 36 provides a heat transport device. The heat exchanger 36 with a power conversion device includes a heat exchanger portion that contains therein a fuel that is a fluid to be cooled, and a power conversion device that generates an air flow through the heat exchanger using the flow of the fuel. And a part. The power converter portion includes a fuel flow turbine, a magnetic coupling device, and a blower. When surplus fuel flows out from the fuel injection pump 26, the surplus fuel flows through the heat exchanger front path 32 until it reaches the inlet 40 of the heat exchanger 36 with a power converter. The inlet 40 is also referred to as a drive impeller fluid inlet for introducing fluid for the drive impeller. When the liquid fuel reaches the inlet 40, the fuel temperature is 40 ° C to 90 ° C. This temperature varies depending on the environmental temperature in which the vehicle is placed and the use state of the vehicle. As an example, if the vehicle 10 is placed on a black asphalt paved road during the day when the outside air temperature is 35 ° C. and the engine 12 is in an idling state, the temperature of the engine room 14 may reach close to 80 ° C. is there.

  When the fuel flows into the heat exchanger with a power converter 36 at the inlet 40, the fuel comes into contact with the plurality of inner blades 44. The inner blade 44 can also be called an inner blade. The internal vane plate 44 is inclined with respect to the flow direction of the fuel that collides with the internal vane plate 44. The inclination of the inner blade 44 is set so as to rotate the inner blade 44 in the clockwise direction, for example. The plurality of inner blades 44 are attached to an annular drive impeller member 48. The driving impeller member 48 is rotatably supported. The rotation of the inner vane 44 gives the drive impeller member 48 a clockwise rotation. The drive impeller member 48 is provided with a plurality of internal drive magnets 50. The internal drive magnet 50 provides an internal drive member. The drive impeller member 48 and the plurality of internal blade plates 44 provide a drive impeller. The plurality of inner blades 44 form a turbine fan. Each of the plurality of inner blades 44 provided on the drive impeller member 48 has a front edge and a rear edge, and the inner blade 44 rotates when the flowing fluid and the inner blade 44 collide. Therefore, the drive impeller member 48 and the plurality of inner blades 44 rotate at the same speed. The rotational speed is directly proportional to the flow rate of the return fuel flowing through the heat exchanger front path 32. That is, the faster the fuel flow in the heat exchanger front path 32, the faster the inner vane plate 44 turns. This is because the internal vane plate 44 and the driving impeller member 48 holding the magnet 50 are disposed in the liquid fuel passage and are in contact with the liquid fuel.

  A power transmission wall 52 is provided outside the driving impeller in the radial direction. The power transmission wall 52 returns to the inside, defines a fuel passage, and supports a driving impeller rotatably inside. The power transmission wall 52 is also a pipe through which the return fuel flows, and prevents the fluid that collides with the inner blade 44 from flowing out to the outside. The power transmission wall 52 is fixed and does not rotate.

  Since the magnet 50 emits and generates a magnetic field around it, the magnetic field is generated through the power transmission wall 52. The magnetic field generated by the internal drive magnet 50 reaches a plurality of external counter magnets 56. The external counter magnet 56 provides an external counter member. The externally facing magnet 56 provides a driven magnet. A driven impeller 54 is disposed on the radially outer side of the power transmission wall 52. The driven impeller 54 is rotatably supported outside the power transmission wall 52. The driven impeller 54 and the power transmission wall 52 are provided coaxially. The externally facing magnet 56 is positioned at the radially inner portion of the driven impeller 54. In one example, the plurality of internal drive magnets 50 have a different polarity from the plurality of external counter magnets 56. The magnetic poles of the magnets 50 and 56 are set so that when one or a plurality of internal drive magnets 50 move, one or a plurality of external counter magnets 56 move in the same direction as the moving direction. ing. The driven impeller 54 is supported in a floating and free state without contacting the power transmission wall 52, and rotates around the power transmission wall 52. For this reason, the plurality of externally opposed magnets 56 are replaced by the magnetic force of the internal drive magnet 50 that applies a rotational force to the driven impeller 54. The externally facing magnet 56 can be embedded in a driven impeller member 58 that is rotatably supported just outside the power transmission wall 52.

  The internal drive magnet 50 and the external counter magnet 56 are magnetically transmitted through the power transmission wall 52 so that the drive impellers 44, 48 and the driven impellers 54, 58, 60 rotate in conjunction with each other. A magnetic coupling device is provided for coupling to the device. In the above configuration, magnets are used for both the internal drive magnet 50 and the external counter magnet 56 in order to provide a magnetic coupling device. Instead of this configuration, a magnet may be provided in only one of the internal drive member and the external facing member, and the other may be replaced with a magnetic body attracted by the magnet. Moreover, you may arrange | position a magnet and a magnetic body alternately. For example, a steel or iron plate may be provided at the position of the externally facing magnet 56 in the driven impeller 54. In that configuration, the internal drive magnet 50 rotates the driven impeller 54 by attracting a steel or iron plate. Such a configuration enables a low-cost configuration compared to a configuration using magnets 50 and 56 both inside and outside.

  In yet another modification, instead of the internal drive magnet 50, steel or iron plates are provided at those positions. In that configuration, when the drive impeller member 48 rotates, the externally opposed magnet 50 is attracted to a steel or iron plate. The externally facing magnet 56 is magnetically coupled with a steel or iron plate to drive the driven impeller 54. Such a configuration enables a low-cost configuration compared to a configuration using magnets 50 and 56 both inside and outside.

  The driven impeller 54 further includes a plurality of driven blade plates 60. The driven blade plate 60 is attached to the driven impeller member 58. When the driven impeller 54 rotates in the clockwise direction by rotating the driving impeller member 48 in the clockwise direction along the arrow 46, each of the impellers 60 in which the impeller 60 rotates in the clockwise direction It has an edge 61 and a trailing edge 63. The vane 60 forcibly sends air to the heat exchanger 66. That is, the blade 60 provides a blower. The plurality of external blades 60 are inclined so as to generate an air flow through the heat exchanger 66 by being driven to rotate. When the driven impeller 54 rotates in the clockwise direction, the air is sucked into the gap 62 between the blade plate 60 and the blade plate 60 because the blade plate 60 is inclined. Air is sucked into a plurality of gaps 62 that are defined between two adjacent blade blades 60 or adjacent to each other and arranged around the entire circumference of the driven impeller 54. Such air flow is indicated by arrows 64 in FIG. As the air flow 64 passes through the driven impeller 54, the air flow 64 passes through the heat exchanger 66 or flows across the heat exchanger 66.

  In the example shown in FIG. 3, when the driven impeller 54 rotates in the first direction, that is, in the clockwise direction, air is pushed by the driven impeller 54 and an air flow 64 is generated. Alternatively, the driven impeller 54 may rotate in the opposite direction, i.e., the counterclockwise second direction, and draw the air flow 65 through the heat exchanger 66. When the air stream 65 is drawn through the heat exchanger 66, the inlet 40 is replaced with the outlet 41 and the outlet 78 is replaced with the inlet 79. The outlet 41 is a driving impeller fluid outlet through which fluid flows after driving the driving impeller. The outlet 78 is a heat exchanger fluid outlet through which the fluid flows after passing through the heat exchanger. The inlet 79 is a heat exchanger fluid inlet for introducing fluid into the heat exchanger. Thus, the inner vane 44 receives fluid from the side of the inner vane 44 to cause counterclockwise rotation of the inner vane 44 to draw air through the heat exchanger 66. This causes counterclockwise rotation of the driven impeller member 58 and the driven blade plate 60 via the internal driving member (magnet) 50 and the external facing member (magnet) 56.

  In FIG. 5, the heat exchanger 66 can be configured similarly to many known heat exchangers. For example, the heat exchanger 66 can have a configuration similar to a radiator fluidly coupled to the internal combustion engine. The heat exchanger 66 has a plurality of tubes 68 arranged in series. The plurality of tubes 68 form a fuel passage in the heat exchanger 66. The plurality of tubes 68 maximizes the distance that liquid fuel must flow in the heat exchanger 66. The plurality of pipes 68 improve the effect of air flowing outside the pipe 68 through which liquid fuel flows. The tube 68 is a thin metal tube.

  One side of the heat exchanger 66 that makes it effective to use the heat exchanger 66 with the power converter 70 is that the inlet 40 is directly connected, coupled, or fastened to the heat exchanger 66. The power conversion device 70 can also be directly connected, coupled, or fastened to the heat exchanger 66 via the power transmission wall 52 of the power conversion device 70 or the like. Further, the heat exchanger 66 may be mounted on the power conversion device 70 by directly welding the outer surface or the outer surface of the heat exchanger 66 to the power conversion device 70. More specifically, the heat exchanger 66 and the power transmission wall 52 may be connected to each other or fastened around their geometric centers 72, 74. The power conversion device 70 can be accompanied by all the components shown in FIGS. 3 and 4 together with the heat exchanger 66, and can constitute the heat exchanger 36 with the power conversion device.

  As shown in FIG. 5, when the liquid fuel flows into the heat exchanger 66 at the heat exchanger inlet 76, the liquid fuel is guided to flow through the plurality of pipes 68 in order, and from the outlet 78 to the outside of the heat exchanger 66. Spill to The liquid fuel at the heat exchanger inlet 76 is heated or warmed. The liquid fuel at the heat exchanger inlet 76, or any liquid other than fuel, is at a high temperature relative to the temperature at which it exits the heat exchanger outlet 78. The liquid fuel radiates heat in the process of flowing through the pipe 68. In the process of flowing through the pipe 68, the liquid fuel is cooled to a temperature lower than the temperature when it flows into the heat exchanger inlet 76. Therefore, at the heat exchanger outlet 78, the cooled liquid fuel which is lower than the temperature when flowing into the heat exchanger inlet 76 flows out.

  In FIG. 6, another embodiment is illustrated. The heat exchanger with a power conversion device 80 includes a power conversion device 70 including a driven impeller 54 and a heat exchanger 67. The driven impeller 54 and the power converter 70 are the same as those shown in FIGS. 3 and 4 and described in detail above. However, there are several differences between the embodiment illustrated in FIGS. 3-4 and the embodiment illustrated in FIG.

  The power transmission wall 52 of the power converter 70 is connected or fastened to the air cone member 82 or the air concentrator 82 by a fastener or welding. The air cone member 82 has a circular air receiving end 84 and a circular air outlet end 86. The air receiving end 84 is larger than the air outlet end 86. The air receiving end 84 receives air. The air receiving end 84 can be positioned opposite the driven impeller 54. If the driven impeller 54 includes a protective frame, the air receiving end 84 can be in contact with or adjacent to the protective frame. The air receiving end 84 can be provided immediately adjacent to the driven impeller 54 such that there is only a minimal clearance between the air receiving end 84 and the driven impeller 54. The minimum gap (for example, space) is designed not to allow a clear amount of air to escape from between the air receiving end 84 of the air cone member 82 and the driven impeller 54. The air cone member 82 is a cylinder corresponding to the outer peripheral surface of the truncated cone.

  Returning to FIG. 6, the air flow 88 passes between the blade plates 60 of the driven impeller 54, is sucked between the blade plates 60 (see FIG. 4), and is sucked into the air cone member 82. When the air flow 88 flows into the air cone member 82, the air flow 88 gradually becomes a convergent flow 90. The flow velocity of the convergent flow 90 gradually increases while flowing in the air cone member 82. The flow velocity of the convergent flow 90 gradually increases until the convergent flow 90 reaches the external air pipe 92. When the convergent flow 90 reaches the external air pipe 92, the air flow 94 has a relatively constant flow velocity over the entire length of the external air pipe 92. The external air tube 92 provides a heat exchanger air tube. The external air pipe 92 defines through holes 100 as a plurality of outlet holes for allowing air to escape from the air passage between the external air pipe 92 and the internal fuel pipe 98. The external air pipe 92 is also an outer wall provided with a plurality of holes for allowing the air flow to flow out. The internal fuel tube provides a heat exchanger internal tube. The air flow 94 that has entered the external air pipe 92 is warmed and discharged from the through hole 100 to the outside. The air flow 94 that has entered the outer air pipe 92 can freely flow around the outer periphery of the inner fuel pipe 98 until it passes through the through hole 100.

  In FIG. 6, the air flow 88 becomes a convergent flow 90. Thereafter, the convergent flow 90 becomes a warmed air flow 94. Thereafter, the air flow 94 is discharged from the external air pipe 92 through the through hole 100. The air flow 94 is warmed compared to the air flow 88. This is because the liquid fuel 102 flowing in the internal fuel pipe 98 radiates heat to the air through the wall of the internal fuel pipe 98. Thus, when heat is transferred to the air stream 94, the temperature of the fuel 102 flowing in the internal fuel tube 98 is higher than the temperature of the air streams 88, 90.

  The outer air tube 92 has a terminal end 104. The end 104 is managed according to the cooling amount to be given to the liquid fuel flowing in the internal fuel pipe 98. At the end of the external air pipe 92, the liquid fuel is taken over by the post-heat exchanger path 34 and returned to the fuel tank 16. The air cone member 82, the external air pipe 92, the internal fuel pipe 98, and the through hole 100 constitute a heat exchanger 67 and function as the heat exchanger 67.

A characteristic component that can be added to the air cone member 82 is a turbulent flow generating member for generating turbulent flow. An example of the turbulent flow generation member is a projection 83 for air provided on the inner peripheral surface of the air cone member 82. The protrusion 83 is provided by, for example, a hemispherical protrusion. The protrusion 83 changes the laminar flow into a turbulent flow, or changes the turbulent flow into a more turbulent flow. Turbulence of the air flow 94 throughout the outer air tube 92 and around the inner fuel tube 98 facilitates cooling of the fuel within the inner fuel tube 98. Another example of the device for turbulent airflow is a barrier plate 85 provided in the air cone member 82. The barrier plate 85 becomes an obstacle to the air flow 90 and generates a turbulent flow downstream thereof. The barrier plate 85 can also be referred to as a deflection plate that deflects the flow of the air flow 90. The barrier plate 85 is an annular plate provided on the outer periphery of the internal fuel pipe 98. The barrier plate 85 is provided by means such as welding, connection, or mounting. The barrier plate 85 can be provided by a bent bar, a straight bar, or a hooked portion. These members impede the air flow 90 through the air cone member 82 and promote turbulence of the air flow through the external air tube 92 .

  As described above by a plurality of different expressions, it can be said that the apparatus for conveying heat includes the heat exchangers 66 and 67. The heat exchangers 66 and 67 have a configuration that can be called, for example, a radiator. The heat exchanger 66 includes a heat exchanger inlet 76 that receives fluid into the heat exchanger 66 and a heat exchanger outlet 78 for exhausting fluid from the heat exchanger 66. The apparatus for conveying heat further includes a power conversion device 70. The power conversion device 70 includes a driving impeller fluid inlet 40 that introduces fluid for the driving impeller, a plurality of internal vane plates 44 that receive fluid from the driving impeller fluid inlet 40, and a rotatably supported drive. An impeller member 48 and a plurality of drive magnets 50 (internal drive members) attached to or embedded in the drive impeller member 48 can be provided. The plurality of inner blades 44 are attached to the drive impeller member 48. The power conversion device 70 can further include a driven impeller member 58 that is rotatably supported. The driven impeller member 58 can include a plurality of external blades 60 attached to the driven impeller member 58. A plurality of external opposing magnets 56 (external opposing members) are attached to or embedded in the driven impeller member 58. The heat exchanger 66 is attached to the power conversion device 70 by means such as a fastening member or welding. The apparatus for conveying heat can further comprise a power transmission wall. The power transmission wall is formed in a cylindrical shape or a tubular shape, and is provided between the plurality of internal drive magnets and the plurality of external counter magnets.

  The power transmission wall 52 contributes to transmitting a magnetic field or power from the plurality of internal drive magnets 50 to the plurality of external counter magnets 56. The outer diameter of the driven impeller 54 as a whole can be made larger than the outer diameter of the power transmission wall 52 as shown in FIG. Thereby, air is supplied into the heat exchanger 66 by the external blades 60, and the inside of the heat exchanger 66 is forcibly blown. The force of the return fuel from the fuel injection pump 26, i.e., the flow of liquid fuel, gives a rotational force to the internal vane plate 44, the driving impeller member 48, and the internal driving magnet 50. As a result, the force of the return fuel flow rotates the magnetic field of the internal drive magnet 50 that passes through the power transmission wall 52. Further, the flow force of the return fuel gives a rotational force to the externally facing magnet 56, the driven impeller member 58, and the external blade plate 60. The same fluid that drove the inner blade 44, that is, the return fuel also flows to the heat exchanger 66. In one example, the return fuel flows into the heat exchanger 66 after driving the inner vane 44. In another example, the return fuel drives the inner vane 44 after passing through the heat exchanger 66. Thus, the cooled fluid is also used to drive a blower for cooling the fluid itself. A heat exchanger inlet 76 for the fluid can be provided on the geometric center 74 of the heat exchangers 66, 67. A heat exchanger inlet 76 or heat exchanger outlet 78 connected directly to the power converter 70 can be located in the geometric center of the heat exchangers 66, 67. In the power conversion device 70, the driving impeller and the driven impeller are arranged coaxially. For this reason, the power converter 70 has a fluid inlet or outlet at its geometric center. Further, the power conversion device 70 has a flow path of air as the second fluid on the radially outer side of the power transmission wall 52. Such a configuration of the heat exchangers 66 and 67 and a configuration of the power conversion device 70 are configured such that the heat exchangers 66 and 67 and the power conversion device 70 are arranged in series, and the heat exchangers 36 and 80 with a power conversion device are provided. A compact configuration is possible.

  The heat exchanger with a power converter 36 can be applied to various applications where heat transfer from one fluid (liquid or gas) to another fluid (liquid or gas) is desired. Therefore, the disclosure of the present invention is not limited to application to the automobile field. Application in the automotive field has been described in connection with the disclosure of the invention. In the automotive field or the transportation automobile field for cooling the liquid fuel, the heat exchanger 36 with the power converter can be provided on the lower side of the vehicle. The heat exchanger with power converter 36 can be provided in the fuel return path 32, 34 between the front engine firewall of the vehicle and the fuel tank 16.
