Description

Air compression device

The present invention relates to an air compression device that produces compressed air.

Air compression devices that generate compressed air have been utilized in a variety of applications. The compressed air generated by the air compression device mounted on a vehicle (for example, a railway vehicle) may be supplied to a pneumatic device that applies a braking force to the brake device of the vehicle or opens and closes the vehicle door. Patent Documents 1 and 2 propose a design of an air compressing device in which a cooler is disposed in the vicinity of a compressor that generates compressed air. Compressed air is supplied from the compressor to the cooler. The cooler effectively cools the compressed air. The temperature of the cooler becomes high by the compressed air flowing inside the cooler. Patent Documents 1 and 2 propose to provide fins to the cooler in order to promote heat dissipation from the cooler. The heat sinks of Patent Documents 1 and 2 protrude in the opposite direction to the compressor. In order to guide the external air taken from the outside of the air compression device around the heat sink of the cooler, the forced heat dissipation from the heat sink of the cooler is generated, and the flow path of the external air must be the flow path of the cooling air used to cool the compressor. Set to different. In this case, the construction of the air compression device is complicated. The designer can also rely on the natural heat dissipation from the heat sink of the cooler to dissipate heat from the cooler. In this case, different flow paths for the fins of the cooler are not required, but the heat dissipation efficiency from the cooler is lowered.

It is an object of the present invention to provide an air compression device having a cooling structure that allows the cooler and the compressor to be effectively cooled simultaneously without requiring a complicated flow path for cooling air. An air compressing apparatus according to an aspect of the present invention includes: a compressor that generates compressed air; and a cooler that forms an internal space into which the compressed air flows. The cooler includes a first cavity forming surface on which the first fin is provided. The compressor includes a second cavity forming surface on which the second fin is provided. The first cavity forming surface and the second cavity forming surface form a cooling duct that allows cooling air that absorbs heat from the compressor and the cooler to flow. The first fins and the second fins protrude into the cooling duct.

<First Embodiment> Under the above prior art, The body of the cooler for the flow of compressed air is located between the fins of the cooler and the fins of the compressor. therefore, If the cooling air supplied through the common flow path cools the fins of the cooler and the heat sink of the compressor, Then the body of the cooler collides with the fluid of the cooling air, Causes, for example, turbulence. This reduces the cooling efficiency. In addition, Because the heat sink of the cooler is away from the heat sink of the compressor, Therefore, in order to fully cool the heat sinks, It is necessary to provide a blower having a large air supply capability. The present inventors have developed even a small air blowing device, In addition to the compressor, it can also be used to effectively cool the compressed air. In the first embodiment, An exemplary cooling technique is illustrated.  Fig. 1 is a conceptual diagram of an air compressing device 100 according to a first embodiment. Referring to Figure 1, The air compressing device 100 will be described.  The air compressor 100 includes a compressor 200 and a cooler 300.

The compressor 200 includes a second cavity forming surface 210 located at a portion opposed to the cooler 300.  The cooler 300 includes a first cavity forming surface 310 located at a portion opposed to the second cavity forming surface 210 of the compressor 200. On the upper side of the second cavity forming surface 210, Forming an upper connecting surface 224, A lower connecting surface 225 is formed on the lower side. On the upper side of the first cavity forming surface 310, Forming an upper connecting surface 334, A lower connecting surface 335 is formed on the lower side. And, The connecting surface 224 above the compressor 200 and the upper connecting surface 334 of the cooler 300 are coupled to each other. also, The lower connecting surface 225 of the compressor 200 and the lower connecting surface 335 of the cooler 300 are coupled to each other.  The second cavity forming surface 210 and the first cavity forming surface 310 are associated with each other and define a cooling duct 400 having a space extending in the horizontal direction. which is, The second cavity forming surface 210 and the first cavity forming surface 310 are each a shape in which the pipe is cut in half. The shape of the space in the cooling duct 400 can also be any shape. However, in the first embodiment, It is formed into a rectangular cross section. therefore, The first cavity forming surface 310 has a first upper surface 310a facing downward, a first side surface 310b extending downward from an end portion of the first upper surface 310a, The first lower surface 310c is connected to the lower end of the first side surface 310b and faces upward. The first side surface 310b is longer than each of the first upper surface 310a and the first lower surface 310c. however, The first side surface 310b may be shorter than the first upper surface 310a and the first lower surface 310c. In this case, The heat sink is protruded from the first side surface 310b, It is also possible to protrude from one of the first upper surface 310a and the first lower surface 310c. Further, the second cavity forming surface 210 has a second upper surface 210a facing downward, a second side surface 210b extending downward from an end portion of the second upper surface 210a, The second lower surface 210c is connected to the lower end of the second side surface 210b and faces upward. The second side surface 210b is longer than each of the second upper surface 210a and the second lower surface 210c. however, The first side surface 310b may be shorter than each of the first upper surface 310a and the first lower surface 310c. In this case, The heat sink is protruded from the second side surface 210b, It is also possible to protrude from one of the first upper surface 310a and the first lower surface 310c. In this case, Also included in the first cavity forming surface 310, The heat sink is disposed on the first side 310b, In the second cavity forming surface 210, The heat sink is provided on the second upper surface 210a or the like.  another, If the space in the cooling duct 400 is formed, for example, in a circular cross section, Then, the first cavity forming surface 310 and the second cavity forming surface 210 are formed in a curved shape. In this case, The fins may also protrude toward the center of the section of the space within the cooling duct 400. or, If the space inside the cooling duct 400 is formed into, for example, a cross-sectional triangular shape, Then, the first cavity forming surface 310 and the second cavity forming surface 210 are formed to be inclined. In this case, The first cavity forming surface 310 and the second cavity forming surface 210 are inclined surfaces facing each other. also, In this case, The heat sink may also protrude toward the center of the cooling duct 400.  Furthermore, The first cavity forming surface 310 and the second cavity forming surface 210 may be the same as shown in the embodiment. But even if it’s not right, As long as one to a plurality of faces (including planes, Inclined surface, At least a part of the curved faces are opposite to each other, It is also possible to form a surface 210 for each cavity, 310 between the other components. also, In this embodiment, The cooling duct 400 is composed of a first cavity forming surface 310 and a second cavity forming surface 210. Can also be included in other components.  also, The first cavity forming surface 310 and the second cavity forming surface 210 may be as shown in this embodiment. In order to be placed in a position opposite to each other, However, the first cavity forming surface 310 and the second cavity forming surface 210 may be disposed in close proximity on the same plane or substantially the same plane. E.g, If the space inside the cooling duct 400 is formed into a rectangular cross section, Alternatively, the first cavity forming surface 310 and the second cavity forming surface 210 may be disposed adjacent to one of the inner side surfaces of the four sides. In this case, For the other inside, It can also be constructed by other components.  The compressor 200 is compressed air, Produces compressed air. The compressor 200 can also be a general scroll compressor. Instead, The compressor 200 can also be a general rotary compressor. And instead, The compression mechanism 200 can also be a general swing compressor. And instead, The compression mechanism 200 can also be a general reciprocating compressor. The principle of this embodiment is not limited to the specific structure of the compressor 200.  The compressed air ejected from the compressor 200 is supplied toward the cooler 300. In the cooler 300, An internal space 301 through which compressed air flows is formed. The compressed air may also pass through a tube member (not shown) that extends across the cooling duct 400. The compressor 200 is supplied to the internal space 301 of the cooler 300. Instead, Compressed air can also pass through the tubular members of the cooling duct 400. The compressor 200 is supplied to the internal space 301 of the cooler 300. The principle of the present embodiment is not limited to a specific supply path of compressed air from the compressor 200 toward the cooler 300.  Cooling air is supplied to the cooling duct 400. Known as a multi-leaf fan unit, Rear curved fan unit, A plurality of air supply devices of the cross flow fan device or the propeller fan device may also be used to supply cooling air to the cooling duct 400. The principle of this embodiment is not limited to the specific supply technique of the cooling air toward the cooling duct 400. another, It is also possible to share the driving unit (motor or the like) of the air blowing device with the driving unit of another device such as a compressor. However, by separately providing the driving portion of the air blowing device independently of the driving portion of the other device, The fan can also be rotated and the cooling air can be delivered to the cooling duct during the period in which the other device is stopped. And can improve the cooling efficiency.  The cooler 300 further includes a first fin 320 that protrudes from the first side face 310b of the first cavity forming surface 310 toward the second side face 210b of the second cavity forming surface 210 of the compressor 200. The compressor 200 further includes a second fin 220 that protrudes from the second side surface 210b of the second cavity forming surface 210 toward the first side surface 310b of the first cavity forming surface 310 of the cooler 300. Heat sink 320, 220 protrudes together into the cooling duct 400.  Cooling air flows into the cooling duct 400. Cooling air flows during the flow in the cooling duct 400, Since the heat sink 320, 220 absorbs heat. the result, The cooler 300 and the compressor 200 are cooled together.  The cooling duct 400 is formed on the first cavity forming surface 310 of the cooler 300, And formed on the second cavity forming surface 210 of the compressor 200, thus, The air compression device 100 does not need to be used to cool such a wide space. therefore, The designer can assign a smaller size value to the air compression device 100.  <Second Embodiment> The designer who designs the air compressing device can also apply various shapes to the heat sink described in connection with the first embodiment. In the second embodiment, Explain the illustrative shape of the heat sink.  2A and 2B are heat sinks 101, A schematic perspective view of 102. Referring to Figures 1 to 2B, Description of the heat sink 101, 102.  The designer of the design air compression device (not shown) can also use the heat sink 101, The shape of 102 is given to the second heat sink 220 described with reference to FIG. The first heat sink 320. Instead, The designer can also make the heat sink 101, 102 protrudes from the inner wall surface of the cooling duct 400A explained with reference to FIG.  As shown in Figure 2A, The heat sink 101 has a flat surface that extends substantially parallel to the flow direction of the cooling air. therefore, The cooling air can smoothly flow along the flat surface of the fins 101.  As shown in Figure 2B, The heat sink 102 has an undulating surface extending in the flow direction of the cooling air. The heat sink 102 has a wider contact area with the cooling air than the heat sink 101. Therefore, the cooling air can absorb a large amount of heat from the heat sink 102.  <Third Embodiment> The air compressing device may have a partition wall disposed inside the cooling duct. If the internal space of the cooling duct is divided into a plurality of smaller spaces by the partition wall, Then the cooling air flowing in the cooling duct is rectified. the result, Cooling air draws a large amount of heat from the compressed air in the compressor and cooler. In the third embodiment, An exemplary air compression device having a partition wall is illustrated.  Fig. 3 is a conceptual diagram of an air compressing device 100A according to a third embodiment. Referring to Figure 3, The air compressing device 100A will be described. The symbol common to the first embodiment means that the requirement of the symbol is functionally common to the first embodiment. therefore, The description of the first embodiment is applied to the requirement of a common symbol.  Similar to the first embodiment, The air compressor 100A includes a compressor 200 and a cooler 300. The description of the first embodiment is applied to these requirements.  The air compressing device 100A further includes a partition wall 410 disposed between the second heat sink 220 and the first heat sink 320. a heat sink 220 protruding in a horizontal direction in the cooling duct 400, 320 different, The partition wall 410 extends in the vertical direction inside the cooling duct 400. The internal space of the cooling duct 400 is divided into a left flow space 411 and a right flow space 412. The left flow space 411 is defined between the partition wall 410 and the first cavity forming surface 310 of the cooler 300. The right flow space 412 is defined between the partition wall 410 and the second cavity forming surface 210 of the compressor 200. Cooling air flows into the left flow space 411 and the right flow space 412.  The partition wall 410 may also abut against the front edge of each of the second heat sink 220 and the first heat sink 320. Can not be reached. When the partition wall 410 abuts against the second heat sink 220 protruding in the right flow space 412, Then, the second heat sink 220 divides the right flow space 412 up and down. When the partition wall 410 abuts against the first heat sink 320 protruding in the left flow space 411, Then, the first heat sink 320 divides the left flow space 411 up and down. In this case, Since the heat of the second heat sink 220 and the first heat sink 320 is released to the partition wall 410, Therefore, the cooling air can effectively extract heat from the compressed air in the compressor 200 and the cooler 300. If the partition wall 410 is away from the heat sink 220, At least one of 320, Heat sink 220, The heat transfer between 320 becomes difficult to produce.  The partition wall 410 can also be connected to the heat sink 220, One or the same material of 320 is formed. Instead, The partition wall 410 can also be connected to the heat sink 220, 320 different materials are formed. E.g, The designer can also choose to use the heat sink 220, The material of 320 has a lower thermal conductivity material as the material of the partition wall 410. In this case, Because the heat between the compressor 200 and the cooler 300 is small, Therefore, complicated thermal interference between the compressor 200 and the cooler 300 becomes difficult to generate. In this case, The control relating to the heat of the compressor 200 and the cooler 300 is facilitated.  <Fourth Embodiment> A designer who designs an air compression device can apply various structures and various shapes to the cooler. In the fourth embodiment, An illustrative cooler is illustrated.  Fig. 4 is a schematic perspective view of a cooler 300B according to a fourth embodiment.

The flow area defined by the first cavity forming surface 310 is recessed from the upper connecting surface 334 and the lower connecting surface 335.  The outer casing 330 includes a plurality of first fins 336 protruding in the flow region. The plurality of first fins 336 extend from the upstream surface 331 toward the downstream surface 332. The front edge of each of the plurality of first fins 336 is substantially flush with the upper connecting surface 334 and the lower connecting surface 335. The front end of each of the plurality of first fins 336 may also be coupled to a compressor, Or in contact with a spacer member disposed between the compressor and the outer casing 330.  The outer casing 330 includes an inflow cylinder 337 that protrudes substantially at the center of the flow region. Compressed air passes through an inflow port 338 surrounded by an inflow cartridge 337. The inner space of the outer casing 330 flows in. Since the cooling air flowing in the flow area absorbs heat from the first cavity forming surface 310 of the predetermined flow area and the plurality of first fins 336, Therefore, the compressed air flowing to the inner space of the outer casing 330 is effectively cooled.  Fig. 5 is a schematic cross-sectional view showing the internal structure of the cooler 300B. Referring to Figure 5, Further, the cooler 300B will be described.  The outer casing 330 includes an upper wall 351, Lower wall 352, Upstream wall 353, And a downstream wall 354.

Both ends of the lower partition wall 362 are away from the upstream wall 353 and the downstream wall 354, respectively.  A center partition wall 363 is formed between the upper partition wall 361 and the lower partition wall 362. The central partition 363 includes a linear wall 364 and a curved wall 365. The linear wall 364 extends generally horizontally from the downstream wall 354. The front end of the straight wall 364 is away from the upstream wall 353. The curved wall 365 is near the inflow port 338, Extending downward from the straight wall 364, It is then bent toward the downstream wall 354. The front end of the curved wall 365 is remote from the downstream wall 354. The linear wall 364 and the curved wall 365 portion partially surround the inflow port 338.  The outer casing 330 is attached to the upper wall 351, Lower wall 352, The upper wall 353 and the downstream wall 354 are surrounded by a substantially rectangular inner space. The first internal flow path 371 is defined, The second internal flow path 372, The third internal flow path 373, The fourth internal flow path 374, And a fifth internal flow path 375.  The first internal flow path 371 is defined by the linear wall 364 and the curved wall 365. The first internal flow path 371 is connected to the inflow port 338. And extending toward the downstream wall 354. The compressed air flowing in from the inflow inlet 338 flows along the first internal flow path 371. And facing the downstream wall 354.  The second internal flow path 372 is defined by the central partition 363 and the lower partition 362. The third internal flow path 373 is defined by the lower partition wall 362 and the lower wall 352. The compressed air reaching the terminal end of the first internal flow path 371 passes through the gap between the front end portion of the curved wall 365 and the downstream wall 354. Flowing downwards. One portion of the compressed air then passes through the second internal flow path 372, Flows toward the upstream wall 353. The other part of the compressed air passes through the third internal flow path 373, Flows toward the upstream wall 353.  The compressed air reaching the terminal end of the third internal flow path 373 passes through the gap between the lower partition wall 362 and the upstream wall 353. Flowing upwards, And it merges with the compressed air at the terminal of the second internal flow path 372. The compressed air at the end of the second internal flow path 372 flows upward through the gap between the linear wall 364 and the upstream wall 353.

The compressed air reaching the terminal end of the fourth internal flow path 374 flows upward through the gap between the upper partition wall 361 and the downstream wall 354, And it flows into the 5th internal flow path 375.  The compressed air then flows along the fifth internal flow path 375, And facing the upstream wall 353. The compressed air is finally exhausted from the check valve 340 disposed near the end of the fifth internal flow path 375.  By the upper wall 351, Lower wall 352, The substantially rectangular inner space surrounded by the upstream wall 353 and the downstream wall 354 is located inside the first cavity forming surface 310 on which the flow region through which the cooling air flows is formed. The flow path of the compressed air is formed by the upper wall 351, Lower wall 352, The upstream wall 353 and the downstream wall 354 surround the flow path in the substantially rectangular inner space. therefore, The heat exchange area becomes longer. therefore, The compressed air is effectively cooled by the cooling air.  The cooling of the compressed air also condenses on the inner wall surface of the outer casing 330. The condensate flows downward under the action of gravity. Finally, it is accumulated in the lowermost flow path (the third internal flow path 373). however, The flow path of the compressed air does not pass through the third internal flow path 373. The inlet 338 is in communication with the check valve 340. therefore, The compressed air can pass through the second internal flow path 372. Facing the check valve 340, Therefore, it is not easy to generate a blockage of compressed air in the cooler 300B.  <Fifth Embodiment> A designer who designs an air compressor can also select a scroll compressor as a compressor.

Referring to FIG. 12B and FIG. 15, The air compressing device 100G will be described.  As shown in Figure 15, The air compressing device 100G is provided with a resin tube 140. The resin pipe 140 is connected to the check valve 340 of the cooler 300B and the manifold 811 of the cooling device 810 (refer to FIG. 12B) (refer to FIG. 12B). therefore, The compressed air is guided from the cooler 300B to the cooling device 810 by the resin tube 140. The resin tube 140 may also be formed of polytetrafluoroethylene or other suitable heat resistant resin. The resin tube 140 extends beyond the area where the cooling air flows. therefore, The resin tube 140 is not easily shaken by the cooling air. The principle of this embodiment is not limited to the specific material used for the resin tube 140.  The designer can follow the design principles described in relation to the various embodiments described above, Design a variety of air compression devices. One of the various features described in relation to one of the various embodiments described above may also be applied to an air compression device as described in connection with the other embodiments.  [Outline of Embodiment] Here, The above embodiments are summarized.  An air compression device according to an aspect of the present invention has: compressor, It produces compressed air; And cooler, It forms an internal space into which the above-mentioned compressed air flows. The cooler includes a first cavity forming surface on which the first fin is provided. The compressor includes a second cavity forming surface on which the second fin is provided. The first cavity forming surface and the second cavity forming surface form a cooling duct that allows cooling air that absorbs heat from the compressor and the cooler to flow. The first fins and the second fins protrude into the cooling duct.  According to the above composition, Compressed air flows into the interior of the cooler. The first cavity forming surface of the cooler and the second cavity forming surface of the compressor form a cooling duct that allows cooling air to flow. Therefore, it is not necessary to provide a wide space in order to secure the space for cooling the cooler and the compressor. And, The first heat sink provided on the first cavity forming surface and the second heat sink provided on the second cavity forming surface protrude together in the cooling duct. The cooling air supplied to the cooling duct is thus forced and efficiently cooled. The first fin and the second fin are cooled by the cooling air flowing in the common cooling duct. Therefore, the designer may not impart a complicated flow path of cooling air to the air compression device.  In the above composition, The first cavity forming surface and the second cavity forming surface may be disposed at positions facing each other. which is, The air compression device has: compressor, It produces compressed air; And cooler, It forms an internal space into which the above-mentioned compressed air flows. The cooler includes a first cavity forming surface at a portion facing the compressor, And a first heat sink provided on the first cavity forming surface. The compressor includes a second cavity forming surface that faces the first cavity of the cooler, And a second heat sink provided on the second cavity forming surface. The first cavity forming surface and the second cavity forming surface form a cooling duct that allows cooling air that absorbs heat from the compressor and the cooler to flow. The first fins and the second fins protrude into the cooling duct.  According to the above composition, The first cavity forming surface and the second cavity forming surface are disposed at positions facing each other. Therefore, at least two side faces of the cooling duct can be formed by the first cavity forming surface and the second cavity forming surface. The cooling duct can be easily constructed.  In the above composition, The air compressing device may further include a partition wall disposed between the first heat sink and the second heat sink. The partition wall may divide the flow space of the cooling air in the cooling duct into a first flow space in which the first heat sink protrudes, And a second flow space in which the second heat sink is protruded.  According to the above composition, The partition wall is disposed between the first heat sink and the second heat sink. Therefore, the cooling air in the cooling duct is rectified. therefore, Because the flow resistance of the cooling air in the cooling duct can be lowered, Therefore, the compressed air and compressor in the cooler are effectively cooled.  In the above composition, The partition wall may have a lower thermal conductivity than the first heat sink and the second heat sink.  According to the above composition, The partition wall has a lower thermal conductivity than the first heat sink and the second heat sink. Therefore, the heat between the compressor and the cooler becomes smaller.  In the above composition, The air compressing device may further comprise a blower for generating the cooling air, And guiding the cooling air to an upstream guiding portion of the cooling duct.  According to the above composition, The upstream guide guides the cooling air generated by the blower to the cooling duct. Therefore, the compressed air and compressor in the cooler are effectively cooled.  In the above composition, The compressor may also have a fixed scroll, And a scroll compressor that cooperates with the fixed scroll and generates the movable scroll of the compressed air. The scroll compressor may also define a cooling flow path for cooling the movable scroll. The fixed scroll tube and the movable scroll tube may be disposed between the cooling duct and the cooling flow path. The upstream guide portion may include a first guide frame surrounding an upstream end of the cooling duct and an upstream end of the cooling flow path.  According to the above composition, The upstream guide portion includes a first guide frame surrounding an upstream end of the cooling duct and an upstream end of the cooling flow path. Therefore, the cooling air generated by the blower is introduced into the cooling duct and the cooling flow path. Since the fixed scroll tube and the movable scroll tube are disposed between the cooling duct and the cooling flow path, Therefore, the compressed air in the cooler, The fixed scroll and the movable scroll are effectively cooled.  In the above composition, The air compression device can further comprise: framework, Forming an exhaust port for exhausting the cooling air; And the second guide frame, It is disposed between the exhaust port and the scroll compressor. The cooling air exhausted from the downstream end of the cooling duct and the downstream end of the cooling flow path is guided to the exhaust port. The second guiding frame may also include: pad, Surrounding the cooling pipe and the downstream end of the cooling flow path; And the downstream edge, It surrounds the above exhaust port.  According to the above composition, The pad of the second guiding frame surrounds the downstream end of the cooling pipe and the downstream end of the cooling flow path, And the downstream edge of the second guiding frame surrounds the exhaust port, Therefore, the cooling air is effectively exhausted from the frame.  In the above composition, The frame body may include a first wall and a second wall opposite to the first wall. The blower and the first guide frame may be disposed between the first wall and the scroll compressor. The second guide frame may be attached to the second wall.  According to the above composition, The blower and the first guide frame are disposed between the first wall and the scroll compressor. And, The second guide frame is attached to the second wall, Therefore, the cooling air generated by the blower passes through the first guide frame, Cooling pipe, Cooling flow path and second guide frame, Exhaust from the exhaust port effectively.  In the above composition, The air compression device can further comprise: Cooling device, It includes a pipeline exposed to the above-described cooling air exhausted from the exhaust port; And at least a portion of the flexible guide tube, The compressed air is guided from the cooler to the pipeline.  According to the above composition, The guiding tube is at least partially flexible, Therefore, it can be deformed according to the vibration generated by the air compression device. Therefore, the vibration of the air compressing device becomes less likely to cause a destructive load on the guide pipe and the portion connected to the guide pipe.  The above air compression device does not need to provide a complicated flow path of cooling air. Together, the cooler and compressor can be effectively cooled together.
