Description

Technical Field

[0001] The utility model relates to the technical field of intercoolers, and in particular to a connected intercooler with a novel structure. Background Art

[0002] The function of an intercooler is to cool the hot, supercharged air, thereby reducing the engine's heat load, increasing intake air volume, and ultimately increasing engine power. Whether it's a supercharged or turbocharged engine, an intercooler is required between the supercharger and the intake manifold. When air enters the turbocharger, its temperature rises significantly and its density decreases accordingly. The intercooler cools this air, cooling it before it enters the engine.

[0003] In the magnetic levitation air compressor industry, in order to reduce operating costs and improve process efficiency, many equipment use traditional independent intercoolers. However, independent intercoolers take up a lot of space, resulting in a large integrated air compressor module and high production costs. At the same time, it brings inconvenience to the transportation of the module and poor maneuverability.

[0004] In view of this, the present invention proposes a coupled intercooler with a novel structure. Utility Model Content

[0005] The utility model proposes a novel structure of a combined intercooler, which solves the problem that the independent structure intercooler in the related art occupies a large space, resulting in a large integrated air compressor module and high production cost, and at the same time brings inconvenience to the module transportation and poor maneuverability.

[0007] The tops of the three-stage core group, the two-stage core group, the first-stage core group and the two connecting water chambers are fixedly connected with a mounting top plate for placing the air compressor host;

[0008] The two ends of the three-stage core group are respectively fixedly connected to the three-stage air outlet hood and the three-stage air inlet hood, the two ends of the two-stage core group are respectively fixedly connected to the two-stage air inlet hood and the two-stage air outlet hood, and the two ends of the one-stage core group are respectively fixedly connected to the one-stage air outlet hood and the one-stage air inlet hood;

[0009] The ends of the third-stage core group and the first-stage core group that are away from each other are respectively provided with water inlet and outlet components and return components.

[0010] Preferably, the composition structure of the tertiary core group, the secondary core group and the primary core group is the same, and four groups of mounting pipe holes are provided at both ends of the tertiary core group, the secondary core group and the primary core group along the length direction of the mounting top plate, and the four groups of mounting pipe holes are equidistantly distributed in the vertical direction.

[0011] Preferably, each of the mounting tube hole groups includes a plurality of mounting tube holes, and two mounting tube holes in opposite positions on the same core group are connected via a heat exchange tube.

[0012] Preferably, the connecting water chamber is a square frame, and three water chamber partitions are equidistantly fixed to the interior of the connecting water chamber, which are used to divide the interior of the connecting water chamber into four spaces. The three water chamber partitions are respectively located between two adjacent upper and lower mounting pipe hole groups.

[0013] Preferably, the water inlet and outlet assembly includes an inlet and outlet end cover fixedly connected to one end of the three-stage core group, and a water outlet port and a water inlet port are fixedly connected on the outer wall of the inlet and outlet end cover. Two diversion partitions are fixedly connected between the inlet and outlet end cover and the three-stage core group, which are used to separate the space enclosed between the inlet and outlet end cover and the three-stage core group.

[0014] Preferably, one of the diverter baffles is fixed between the two mounting tube hole groups at the bottom and the second bottom, and the other diverter baffle is fixed between the two mounting tube hole groups at the top and the second top.

[0015] Preferably, the return assembly includes a return end cover fixedly connected to the end of the first-stage core group, and a partition plate is fixedly connected between the return end cover and the first-stage core group, and the space enclosed between the return end cover and the first-stage core group is evenly divided into two sections by the partition plate.

[0017] The working principle and beneficial effects of the utility model are as follows:

[0018] The utility model is a combined intercooler composed of a first-stage, a second-stage, and a third-stage core group, an inlet and outlet water assembly, a return assembly, a first-stage, a second-stage, and a third-stage air inlet hood, a first-stage, a second-stage, and a third-stage air outlet hood, a connecting water chamber, a connecting top plate and other structures. Among them, the first-stage, the second-stage, and the third-stage core group are connected to form a combined core group through the connecting water chamber, and the heat exchange pipe is connected in series. The heat exchange pipe flow channel is formed by the inlet and outlet water assembly and the return assembly, so that the three chambers are independent of each other. The inlet and outlet directions of the three chambers are different. Instead of the traditional counter-flow design, the pipe adopts a straight-down flow arrangement, and a cross-flow design is used to solve the problem of different air side flow directions. No cooling pipe is set in the connecting water chamber to ensure the bypass problem between the pipe process, so that the cooling water flows in an "S"-shaped circulation manner. The first, second, and third-stage air intake hoods and the first, second, and third-stage air outlet hoods combine the air cavities into three air-side channels with different pressure levels. The first, second, and third-stage air cavities are independent of each other to accommodate the three-stage pressurization and cooling of the air compressor. The connecting top plate strengthens the connection between the first, second, and third-stage core groups and supports the air compressor mainframe. This new combined intercooler has high heat transfer efficiency, a compact structure, easy transportation, excellent vibration resistance, good fluidity of the medium in the tubes, and easy drainage, maintenance, and replacement. Compared with traditional three-stage independent intercoolers, the production cost is lower, and it has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 5 A novel, coupled intercooler structure comprises a tertiary core assembly 2, a secondary core assembly 5, and a primary core assembly 7 arranged in a straight line. Connecting water chambers 4 are provided between the tertiary core assembly 2 and the secondary core assembly 5, and between the secondary core assembly 5 and the primary core assembly 7. These two connecting water chambers 4 connect the tertiary core assembly 2, the secondary core assembly 5, and the primary core assembly 7 in series. A mounting plate 12 is fixed to the tops of the tertiary core assembly 2, the secondary core assembly 5, the primary core assembly 7, and the two connecting water chambers 4, for accommodating the air compressor mainframe.

[0028] Furthermore, the composition structure of the tertiary core group 2, the secondary core group 5 and the primary core group 7 is the same. Four groups of mounting pipe hole groups 15 are provided at both ends of the tertiary core group 2, the secondary core group 5 and the primary core group 7 along the length direction of the mounting top plate 12, and the four groups of mounting pipe hole groups 15 are equidistantly distributed in the vertical direction.

[0029] Furthermore, each mounting tube hole group 15 includes a plurality of mounting tube holes, and two mounting tube holes in opposite positions on the same core group are connected through the heat exchange tube 16 .

[0030] It should be noted that the connecting water chamber 4 is a square frame, with three water chamber baffles 14 fixedly attached at equal intervals inside it, dividing the interior of the connecting water chamber 4 into four compartments. The three water chamber baffles 14 are respectively located between two adjacent mounting pipe hole groups 15. Furthermore, the connecting water chamber 4 is sealed to the core assembly via a sealing gasket. A drain plug 17 is installed at the bottom of the side wall of the connecting water chamber 4. The drain plug 17 is connected to a drain hole provided at the bottom of the side of the connecting water chamber 4 to solve the problem of draining the connecting water chamber 4 during maintenance.

[0031] Specifically, the ends of the tertiary core group 2 and the primary core group 7 that are away from each other are respectively provided with an inlet and outlet water component 1 and a return component 13. Since the tertiary core group 2, the secondary core group 5 and the primary core group 7 are distributed along the length direction of the mounting top plate 12 at both ends thereof, four groups of mounting pipe hole groups 15 are provided. The four groups of mounting pipe hole groups 15 are equidistantly distributed in the vertical direction, and each group of mounting pipe hole groups 15 includes multiple mounting pipe holes. The two mounting pipe holes in the same core group are connected by a heat exchange pipe 16, so that the primary core group 7, the secondary core group 5, the tertiary core group 2 and the connecting water chamber 4 are connected as a whole to form a combined core group, so that when the cooling water enters the heat exchange pipe 16 inserted in the mounting pipe hole group 15 located at the bottom side of the tertiary core group 2, the cooling water can flow in an "S"-shaped circulation manner.

[0032] See also Figure 1 and Figure 2 The two ends of the three-stage core group 2 are fixedly connected with the three-stage air outlet hood 3 and the three-stage air inlet hood 9, the two ends of the two-stage core group 5 are fixedly connected with the two-stage air inlet hood 6 and the two-stage air outlet hood 10, and the two ends of the one-stage core group 7 are fixedly connected with the one-stage air outlet hood 8 and the one-stage air inlet hood 11.

[0033] Furthermore, the water inlet and outlet assembly 1 includes an inlet and outlet end cover 103 fixedly connected to one end of the tertiary core group 2, and a water outlet port 101 and a water inlet port 102 are fixedly connected on the outer wall of the inlet and outlet end cover 103. Two diverter baffles 104 are fixedly connected between the inlet and outlet end cover 103 and the tertiary core group 2, which are used to separate the space enclosed between the inlet and outlet end cover 103 and the tertiary core group 2; one of the diverter baffles 104 is fixedly connected between the two mounting pipe hole groups 15 on the bottom side and the second bottom side, and the other diverter baffle 104 is fixedly connected between the two mounting pipe hole groups 15 on the top side and the second top side.

[0034] Furthermore, the return assembly 13 includes a return end cover 1301 fixed to the end of the first-stage core group 7, and a partition plate 1302 is fixed between the return end cover 1301 and the first-stage core group 7, and the space enclosed between the return end cover 1301 and the first-stage core group 7 is evenly divided into two sections by the partition plate 1302.

[0035] Specifically, when the cooling water is injected into the lower space of the inlet and outlet end cover 103 through the water inlet port 102, the cooling water will be discharged into the heat exchange tube 16 inserted in the installation tube hole group 15 located at the bottom side of the tertiary core group 2, and the cooling water will be transported to the lowest space of one of the connecting water chambers 4 through the heat exchange tube 16 on the bottom side of the tertiary core group 2. Then, the cooling water will enter the heat exchange tube 16 inserted in the installation tube hole group 15 on the bottom side of the secondary core group 5, and then, the cooling water will be transported to the lowest space of another connecting water chamber 4 through the heat exchange tube 16 on the bottom side of the secondary core group 5. Finally, the cooling water will flow into the lower space of the partition plate 1302 through the heat exchange tube 16 on the bottom side of the primary core group 7. As the cooling water in the space below the partition plate 1302 continues to accumulate, the cooling water will flow back to the interlayer space between the two diversion partitions 104 inside the inlet and outlet end cover 103 through the heat exchange tubes 16 inserted in all the sub-bottom-layer installation pipe hole groups 15 and the two spaces connecting the 4 sub-bottom layers of the water chamber. As the amount of cooling water in the interlayer space between the two diversion partitions 104 gradually increases, the cooling water will be discharged into the upper space of the partition plate 1302 through the heat exchange tubes 16 inserted in all the sub-top-layer installation tube hole groups 15 and the space of the two sub-top layers connecting the water chambers 4. As the amount of cooling water in the upper space of the partition plate 1302 gradually increases, the cooling water will flow back to the upper space inside the inlet and outlet end cover 103 through the heat exchange tubes 16 inserted in all the top-layer installation tube hole groups 15 and the space of the two top layers connecting the water chambers 4, and finally be discharged through the water outlet port 101, so that the cooling water flows in an "S"-shaped circulation manner, thereby being able to perform heat exchange cooling on the gas flowing through the first-stage core group 7, the second-stage core group 5, and the third-stage core group 2.

[0036] Working principle and usage process: When working, first, the cooling water is injected into the space below the inlet and outlet end cover 103 through the water inlet port 102. As the cooling water in the space below the inlet and outlet end cover 103 increases instantly, the cooling water will be discharged into the heat exchange tube 16 inserted in the installation tube hole group 15 located at the bottom side of the tertiary core group 2, and the cooling water will be transported to the lowest space of one of the connecting water chambers 4 through the heat exchange tube 16 on the bottom side of the tertiary core group 2. Then, the cooling water enters the heat exchange tube 16 inserted in the installation tube hole group 15 on the bottom side of the secondary core group 5, and then, the cooling water is transported to the lowest space of another connecting water chamber 4 through the heat exchange tube 16 on the bottom side of the secondary core group 5. Finally, the cooling water flows into the space below the partition plate 1302 through the heat exchange tube 16 on the bottom side of the primary core group 7.

[0037] As the cooling water in the space below the partition plate 1302 continues to accumulate, the cooling water will flow back to the interlayer space between the two diversion partitions 104 inside the inlet and outlet end cover 103 through the heat exchange tubes 16 inserted in all the sub-bottom-layer installation pipe hole groups 15 and the two spaces connecting the 4 sub-bottom layers of the water chamber.

[0038] Then, as the cooling water in the interlayer space between the two diversion partitions 104 gradually increases, the cooling water will be discharged into the upper space of the partition plate 1302 through the heat exchange tubes 16 inserted in all the sub-top-layer installation tube hole groups 15 and the space of the two sub-top layers connecting the water chambers 4. As the cooling water in the upper space of the partition plate 1302 gradually increases, the cooling water will flow back to the upper space inside the inlet and outlet end cover 103 through the heat exchange tubes 16 inserted in all the top-layer installation tube hole groups 15 and the space of the two top layers connecting the water chambers 4, and finally be discharged through the water outlet port 101, so that the cooling water flows in an "S"-shaped circulation manner.

[0039] Afterwards, while the cooling water flows in an "S"-shaped circulation, the hot gas exhausted by the air compressor is first transported to the first-stage air intake hood 11, transmitted through the first-stage core group 7, and discharged through the first-stage air outlet hood 8. During this process, the hot gas inside the first-stage core group 7 will exchange heat with the outer wall of the heat exchange tube 16 inside the first-stage core group 7, forming a first-stage cooling. The gas after the first-stage cooling will enter the second-stage volute of the supercharger for supercharging. The supercharged high-temperature gas will then enter the second-stage air intake hood 6, and be transported to the second-stage air outlet hood 10 through the second-stage core group 5 for discharge. The gas will exchange heat with the heat exchange tube 16 in the second-stage core group 5, forming a second-stage cooling. And so on, completing the third-stage cooling of the gas.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
