- FIG. 1 is a plan view of a compressor with a cooling function according to an embodiment of the present invention.
- FIG. 2 is a cross-sectional view taken along the line II-II in FIG.
- FIG. 3 is a
- FIG. 10A is a comparison result of the temperature efficiency characteristics of the intercooler of the compressor with a cooling function shown in FIG. 1 which is an embodiment of the present invention and the intercooler of the compressor with a cooling function of Patent Document 1.
- FIG. 10B shows a comparison result of temperature efficiency characteristics between the aftercooler of the compressor with cooling function shown in FIG. 1 which is an embodiment of the present invention and the aftercooler of the compressor with cooling function of Patent Document 1. It is a graph.
- the intercooler 41 is a cooling unit for the low-pressure compressor 23 and includes a low-pressure cooling case 33 and a low-pressure heat exchanger 43.
- a drain space 49 is formed below the low-pressure side heat exchanger 43 in the low-pressure side cooling chamber 42, and is generated when the compressed air passes through the low-pressure side heat exchanger 43 and is cooled. The condensed water that falls is dropped from the low-pressure side heat exchanger 43 and stored in the drain space 49.
- a low pressure side discharge port 46 is disposed on the extension of the upper inner wall surface 47a, and the low pressure side discharge port 46 is connected to the low pressure side communicating from the low pressure side cooling chamber 42 to the outside as shown in FIG.
- a discharge passage 25 is connected.
- the low-pressure side discharge passage 25 is formed so as to extend in the vertical direction along the upper inner wall surface 47a in a front view and to extend obliquely with respect to the vertical direction in a side view. Thereby, the compressed air that has passed through the low-pressure side heat exchanger 43 is redirected upward due to the curvature of the lower inner wall surface 47b, and is guided to the low-pressure side outlet 46 along the upper inner wall surface 47a. It is discharged from the low pressure side cooling chamber 42 to the high pressure side compressor 26 through the low pressure side discharge passage 25.
- the high pressure side heat exchanger 53 is inserted and installed in the high pressure side cooling chamber 52 from the lower side of FIG. In a state where the high-pressure side heat exchanger 53 is installed, a flow path of compressed air is formed in the high-pressure side cooling chamber 52 along the horizontal direction (the left-right direction in FIGS. 2 and 4). Further, the high-pressure side heat exchanger 53 is provided with a partition wall 54 on the upper and lower surfaces and the front end surface in the insertion direction. The partition wall 54 partitions the periphery of the high-pressure side heat exchanger 53 into an inflow-side cooling chamber 52in having a high-pressure side inlet 55 and a discharge-side cooling chamber 52out having a high-pressure side outlet 56.
- the high-pressure side heat exchanger 53 having the upper surface of the high pressure side heat exchanger 53, the case upper surface 34a, and the upper inner wall surface 57a as inner walls, a flow of air having a large counterclockwise kinetic energy is generated. Then, this air flow guides the taken-in air to the high-pressure side discharge port 56 while taking in the air that has come out of the high-pressure side heat exchanger 53 and is rolled up by the lower inner wall surface 57 b.
- a high-pressure side discharge port 56 that extends outward and opens upward is disposed above the boundary portion 57c.
- the high-pressure side discharge port 56 has a high-pressure side discharge port 56 as shown in FIG.
- the intercooler 41 and the aftercooler 51 are set so that the low-pressure side inlet 45 and the high-pressure side inlet 55 are adjacent to each other with the partition wall 32 interposed therebetween, so that high-temperature compressed air immediately after being compressed by the compressor. Are adjacent to each other, and the compressed air after cooling is heated by the high-temperature compressed air, thereby preventing the cooling efficiency from deteriorating.
- the curvature of the upper inner wall surface 47a is set to 0, the low pressure side discharge port 46 is disposed on the extension of the upper inner wall surface 47a, and the low pressure side discharge passage 25 communicating from the low pressure side discharge port 46 to the outside is provided.
- the cooling efficiency can be further improved.
- FIG. 8C is a view showing the air flow field in the cross section (outlet side cross section) along the line VIII-c in FIG. 8A, and is discharged from the outflow side cooling chamber 42out of the cooling case 41. The state of the flow of air flowing out to the passage 25 is shown.
- FIG. 9A is a diagram showing an air flow field in the cooling case of the compressor with a cooling function according to the embodiment of the present invention.
- FIG. 9B is a view showing the result of the air flow field analysis in the cross section (inlet side cross section) along the line IX-b in FIG. 9A, specifically, the inflow from the inflow passage 24. The state of the flow of air flowing into the side cooling chamber 42in is shown.
- FIG. 9A is a diagram showing an air flow field in the cooling case of the compressor with a cooling function according to the embodiment of the present invention.
- FIG. 9B is a view showing the result of the air flow field analysis in the cross section (inlet side cross section) along the line IX-b in
- 9C is a diagram showing an air flow field in a cross section (outlet side cross section) along the line IX-c in FIG. 9A, from the outflow side cooling chamber 42out of the cooling case 41 to the discharge passage 25. It shows the state of the air flow flowing out.
- FIG. 8B in the cross section on the inlet side of the cooling case 41, air convects clockwise in the space between the inlet of the heat exchanger 43 and the side wall of the inflow side cooling chamber 42in. (Arrows A1 to A4). Specifically, in this space, the air flowing in from the inflow passage 24 changes to a rightward flow on the upper surface of the heat exchanger 43, and further changes to a downward flow by the side wall of the inflow side cooling chamber 42in (arrow A2).
- the flow of compressed air in the cooling chamber is rectified and the compressed air smoothly flows in the heat exchanger. Can be improved. Moreover, in the said compressor, since the winding-up of the condensed water stored in the drain space is suppressed, the condensed water conveyed to the downstream side is suppressed.
