Description

Technical Field

[0001] The present invention relates to the technical field of automobile intercoolers, and in particular to an automobile water-cooled turbocharged air-cooling heat exchanger. Background Art

[0002] The intercooler is a turbocharger accessory, typically installed between the supercharger and the engine's intake manifold. After turbocharging, the air temperature rises. Directly charging the supercharged air into the cylinders can easily cause detonation, which is detrimental to power. Therefore, before the supercharged air is fed into the cylinders, it must be cooled to lower its temperature and increase its density, thereby further enhancing the supercharger's boosting effect. The intercooler's function is to cool the supercharged air exiting the supercharger. This cooling process lowers the air temperature, thereby increasing its density and improving charging efficiency, ultimately boosting engine power and reducing emissions.

[0003] Existing intercoolers include air-cooled and water-cooled types. The principle of a water-cooled intercooler is to install cooling water pipes or cooling plates inside the intercooler. Cooling water in these pipes and cooling plates continuously flows. When the flowing high-temperature air comes into contact with the cooling water pipes or cooling plates, the flowing cooling water removes the heat from the charge air. For example, patent publication number CN112555018B describes a water-cooled turbocharged air cooling heat exchanger. Its main technical approach is to extend the gas flow field through S-shaped flow channel plates, increase the flow resistance along the flow path, and enhance the gas heat exchange efficiency. At the same time, the stamping process of the parts is used to generate a water-side flow channel on the back of the flow channel. The flow inside the flow channel is disturbed by ribs and bumps, so that the two media are closely fitted and flow in opposite directions. This enhances the overall heat exchange effect while ensuring the temperature uniformity of the entire product core. After analysis by the applicant, the disadvantage of this technical solution is that in the above solution, the high-temperature air will come into contact with the cooling water that has absorbed heat when entering, and will come into contact with the cooling water that has not absorbed heat when discharging. Although the overall temperature of the high-temperature air can be cooled evenly, this results in the high-temperature air inlet area failing to fully utilize the low-temperature cooling water, resulting in insufficient initial cooling of the high-temperature air, thereby reducing the overall cooling effect. Summary of the Invention

[0004] The purpose of the present invention is to address the shortcomings of the existing technology and provide a water-cooled turbocharged air cooling heat exchanger for an automobile to solve the technical problem of poor high-temperature air cooling effect in the existing technology.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A water-cooled turbocharged air-cooled heat exchanger for an automobile comprises a heat exchanger body, the heat exchanger body comprising an outer shell and an intake manifold and an exhaust manifold mounted at both ends of the outer shell, the heat exchanger further comprising a heat exchange plate, the outer shell being provided with a plurality of mounting holes extending through the outer shell along its long side, a plurality of heat exchange plates being mounted in the mounting holes, a plurality of air flow passages being arranged in the outer shell, the air flow passages being located between two adjacent heat exchange plates, a liquid inlet and a liquid drain being respectively provided at both ends of the heat exchange plates, the liquid inlets on the plurality of heat exchange plates being connected to a first junction box, a liquid inlet pipe being connected to the first junction box, the liquid drains on the plurality of heat exchange plates being connected to a second junction box, and the second junction box being connected to the liquid drain pipe.

[0007] As a preferred embodiment of the above technical solution, a diverter plate is provided in the heat exchange plate, the diverter plate is located at the liquid inlet, a baffle is provided on the side of the diverter plate away from the diverter plate, and a guide plate is symmetrically provided in the heat exchange plate, the end of the diverter plate faces the guide plate, and the guide plate faces the baffle.

[0008] As a preferred embodiment of the above technical solution, a heat exchange component is installed on the intake manifold and the exhaust manifold, and the heat exchange component includes a pre-cooling spiral tube, which is sleeved on the outer periphery of the intake manifold, and one end of the pre-cooling spiral tube is connected to the junction box 2 through a shunt pipe.

[0009] As a preferred embodiment of the above technical solution, the heat exchange component also includes a re-cooling spiral tube, which is sleeved on the outer periphery of the exhaust manifold. One end of the re-cooling spiral tube is connected to the second junction box through a shunt tube, and the ends of the pre-cooling spiral tube and the re-cooling spiral tube are connected through a connecting tube, and a drain pipe is provided on the connecting tube.

[0010] As a preferred embodiment of the above technical solution, a heat dissipation component is installed at the discharge end of the heat exchange plate, and the heat dissipation component includes a turbine and several heat dissipation fans. A turbine is rotatably installed at the discharge port of the heat exchange plate, and several heat dissipation fans are rotatably installed on the heat exchange plate. The turbine is connected to the heat dissipation fan through a transmission member, and the several heat dissipation fans are also connected to each other through a transmission member.

[0011] As a preferred embodiment of the above technical solution, a plurality of heat sinks are provided on the heat exchange plate, and the plurality of heat sinks are located below a plurality of heat dissipation fan blades.

[0012] As a preferred embodiment of the above technical solution, a plurality of heat insulation plates are provided on the shell, and the heat insulation plates are located between an upper heat exchange plate and a lower group of heat dissipation components.

[0013] As a preferred embodiment of the above technical solution, a plurality of inclined guide plates are provided in the intake manifold and the exhaust manifold.

[0014] The beneficial effects of the present invention are:

[0015] 1. In the present invention, high-temperature air enters the housing through the intake manifold and flows along a plurality of airflow channels to the exhaust manifold. As the high-temperature air flows through the airflow channels, cooling water flowing through the heat exchange plates above and below the airflow channels exchanges heat with the high-temperature air, cooling each portion of the high-temperature air discharged from the exhaust manifold. The coordination of the diverter plate, baffle, and two guide plates ensures that the coolant entering the heat exchange plates from the liquid inlet covers the entire interior of the heat exchange plates and flows toward the liquid outlet. This ensures that the flow direction of the cooling water is nearly perpendicular to the flow direction of the high-temperature air. As the high-temperature air flows, the temperature of the cooling water at all locations within the heat exchange plates remains consistent, enabling continuous heat exchange with the high-temperature air and improving the heat exchange effect.

[0016] 2. In the present invention, due to the long air flow channel, the portion of the heat exchange plate located inside the housing is relatively narrow. This shortens the time that the cooling water stays inside the housing during circulation, thereby ensuring that the temperature of the cooling water inside the heat exchange plate remains low. This allows the heat exchange plate to continuously exchange heat with the high-temperature air, further improving the heat exchange effect.

[0017] 3. In the present invention, since the cooling water stays in the heat exchange plate for a short time, the heat absorbed by the unit cooling water is less, and the cooling water temperature rises less. At this time, a part of the cooling water discharged into the junction box 2 enters the pre-cooling spiral tube through the shunt pipe, so that the cooling water can preliminarily cool the high-temperature air that is about to enter the shell, and cooperate with the heat exchange plate to cool the high-temperature air, which can further improve the cooling effect of the high-temperature air; another part of the cooling water entering the junction box 2 will pass through another shunt pipe into the re-cooling spiral tube, so that the cooling water can once again cool the high-temperature air that has been heat-exchanged and cooled, further improving the cooling effect of the high-temperature air.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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 any creative efforts shall fall within the scope of protection of the present invention.

[0028] like Figure 1-Figure 5 As shown, a water-cooled turbocharged air-cooled heat exchanger for an automobile includes a heat exchanger body 1, which includes a shell 2 and an intake manifold 3 and an exhaust manifold 4 installed at both ends of the shell 2. The heat exchanger also includes a heat exchange plate 5. The shell 2 is provided with a plurality of mounting holes 21 along its long side direction. A plurality of heat exchange plates 5 are installed in the plurality of mounting holes 21. The shell 2 is provided with a plurality of air flow channels 22, and the air flow channels 22 are located between two adjacent heat exchange plates 5. A liquid inlet 51 and a liquid drain port 52 are respectively provided at both ends of the heat exchange plate 5. The liquid inlets 51 on the plurality of heat exchange plates 5 are connected to a junction box 1 7, and a liquid inlet pipe 71 is connected to the junction box 1 7. The liquid drain ports 52 on the plurality of heat exchange plates 5 are connected to a junction box 2 8, and the junction box 2 8 is connected to a liquid drain pipe 95.

[0029] Furthermore, a diverter plate 53 is provided in the heat exchange plate 5, and the diverter plate 53 is located at the liquid inlet 51. A baffle 54 is provided on the side of the diverter plate 53 away from the diverter plate 53. A guide plate 55 is symmetrically provided in the heat exchange plate 5, and the end of the diverter plate 53 faces the guide plate 55, and the guide plate 55 faces the baffle 54.

[0030] In actual use of this embodiment, high-temperature air enters the housing 2 through the intake manifold 3 and flows along the plurality of air channels 22 to the exhaust manifold 4. As the high-temperature air flows through the air channels 22, the cooling water flowing through the heat exchange plates 5 above and below the air channels 22 exchanges heat with the high-temperature air, thereby cooling each portion of the high-temperature air discharged from the exhaust manifold 4.

[0031] The coordination of the diverter plate 53, the baffle 54, and the two guide plates 55 allows the coolant entering the heat exchange plate 5 from the liquid inlet 51 to cover the entire interior of the heat exchange plate 5 and flow toward the liquid outlet 52. This ensures that the flow direction of the cooling water is nearly perpendicular to the flow direction of the high-temperature air. When the high-temperature air flows, the temperature of the cooling water at all locations within the heat exchange plate 5 remains consistent, allowing the high-temperature air to be continuously heat exchanged, thereby improving the heat exchange effect.

[0032] Since the air flow channel 22 is long, the portion of the heat exchange plate 5 located inside the shell 2 is relatively narrow. As a result, the cooling water stays in the shell 2 for a shorter time during circulation, thereby ensuring that the temperature of the cooling water in the heat exchange plate 5 always remains low, further allowing the heat exchange plate 5 to continuously exchange heat with the high-temperature air, thereby further improving the heat exchange effect.

[0033] like Figure 1 、 Figure 2 and Figure 7 As shown, a heat exchange component 9 is installed on the intake manifold 3 and the exhaust manifold 4. The heat exchange component 9 includes a pre-cooling spiral tube 91. The pre-cooling spiral tube 91 is sleeved on the outer periphery of the intake manifold 3. One end of the pre-cooling spiral tube 91 is connected to the junction box 2 8 through a shunt tube 93.

[0034] Furthermore, the heat exchange component 9 also includes a sub-cooling spiral tube 92, which is sleeved on the outer periphery of the exhaust manifold 4. One end of the sub-cooling spiral tube 92 is connected to the junction box 8 through a diverter tube 93. The ends of the pre-cooling spiral tube 91 and the sub-cooling spiral tube 92 are connected through a connecting tube 94, and a drain pipe 95 is provided on the connecting tube 94.

[0035] In actual application, since the cooling water stays in the heat exchange plate 5 for a short time, the heat absorbed by the unit cooling water is small, and the cooling water temperature rises slightly. At this time, a portion of the cooling water discharged into the second junction box 8 enters the pre-cooling spiral tube 91 through the diverter pipe 93, so that the cooling water can initially cool the high-temperature air about to enter the housing 2. In combination with the cooling of the high-temperature air by the heat exchange plate 5, the cooling effect of the high-temperature air can be further improved.

[0036] Another part of the cooling water entering the junction box 2 8 will enter the re-cooling spiral tube 92 through another diversion pipe 93, so that the cooling water can cool down the high-temperature air that has been heat-exchanged and cooled again, further improving the cooling effect on the high-temperature air.

[0037] like Figure 6As shown, a heat dissipation assembly 6 is installed at the discharge end of the heat exchange plate 5. The heat dissipation assembly 6 includes a turbine 61 and a plurality of heat dissipation fans 62. The turbine 61 is rotatably installed at the discharge port 52 of the heat exchange plate 5. A plurality of heat dissipation fans 62 are rotatably installed on the heat exchange plate 5. The turbine 61 is connected to the heat dissipation fan 62 through a transmission member 63, and the plurality of heat dissipation fans 62 are also connected to each other through the transmission member 63.

[0038] Furthermore, a plurality of heat sinks 64 are provided on the heat exchange plate 5 , and the plurality of heat sinks 64 are located below the blades of the plurality of heat dissipation fans 62 .

[0039] In one case of this embodiment, the transmission member 63 may be a component capable of synchronous transmission, such as a pulley and a belt.

[0040] In actual application of this embodiment, when the cooling water is discharged from the drain port 52, it will drive the turbine 61 to rotate. The turbine 61 rotates the cooling fans 62 through the transmission parts 63, and the cooling fans 62 will dissipate heat to the heat exchange plate 5. On the one hand, the heat is directly dissipated to the heat exchange plate 5 itself, thereby improving the heat exchange efficiency of the heat exchange plate 5 and further improving the heat exchange effect on the high-temperature air; on the other hand, the cooling water after absorbing heat is preliminarily dissipated, thereby ensuring that the temperature of the cooling water entering the heat exchange component 9 is not too high, thereby ensuring that the cooling water can preliminarily cool the high-temperature air that is about to enter the outer shell 2 and cool the high-temperature air that has been heat exchanged and cooled again, thereby ensuring the heat exchange effect of the cooling water; in conjunction with the heat sinks 64, the heat dissipation effect of the cooling fan 62 on the heat exchange plate 5 and the cooling water can be further improved.

[0041] like Figure 3 As shown, a plurality of heat insulation plates 23 are provided on the housing 2 , and the heat insulation plates 23 are located between an upper heat exchange plate 5 and a lower group of heat dissipation components 6 .

[0042] In actual application of this embodiment, since the heat dissipation fan 62 blows heat toward the upper heat exchange plate 5 when dissipating heat, the upper heat exchange plate 5 is blocked by the heat insulation plate 23 to prevent heat from contacting the heat exchange plate 5, thereby ensuring the heat dissipation effect of the heat dissipation fan 62 on the heat exchange plate 5 and the cooling water, thereby improving the cooling effect on the high-temperature air.

[0043] like Figure 4 As shown, a plurality of inclined guide plates 10 are provided in both the intake manifold 3 and the exhaust manifold 4 .

[0044] In actual application of this embodiment, the guide plates 10 in the intake manifold 3 evenly distribute the high-temperature air entering the housing 2 in the air flow passages 22 and prevent the high-temperature air from flowing too fast, thereby improving the heat exchange effect of the heat exchange plate 5 on the high-temperature air.

[0045] The guide plates 10 in the exhaust manifold 4 prevent the high-temperature air from being discharged quickly, thereby increasing the heat exchange time of the high-temperature air and further improving the heat exchange effect of the heat exchange plate 5 on the high-temperature air.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
