Description

Technical Field

[0001] This application relates to the field of intercoolers, and more particularly to a water-cooled intercooler. Background Technology

[0002] Turbocharged engines use an intercooler to cool the combustion air, increasing air density to increase intake volume and boost engine power. The intercooler is an integral part of the engine; its function is to cool the air. Hot air passes through the intercooler for cooling before entering the engine, preventing hot gases from directly entering and causing engine knocking or even damage and stalling.

[0003] In related technologies, Chinese patent CN216518264U discloses a novel plate-fin water-cooled intercooler, including an air inlet chamber, an air outlet chamber, and an intercooler core. The air inlet chamber and the air outlet chamber are respectively connected to the left and right sides of the intercooler core. The intercooler core includes two main plates, two side plates, several cooling water tanks, and an air outlet pipe. The cooling water tanks are located between adjacent air outlet pipes or between the air outlet pipes and the side plates. The cooling water tanks are filled with coolant. The top of the cooling water tank near the air inlet chamber is provided with a water inlet pipe. The length of the cooling water tank is less than the length of the air outlet pipe.

[0004] When the gas in the intake chamber enters the exhaust pipe from one end and moves toward the exhaust chamber, the coolant in the cooling water tank can quickly exchange heat and cool the air sandwiched between the cooling water tanks in the exhaust pipe, so that the gas entering the exhaust chamber from the exhaust pipe has a lower temperature.

[0005] The gas temperature in the intake chamber is relatively high. The high-temperature gas enters the exhaust duct from one end, making the temperature of the end of the exhaust duct near the intake chamber relatively high. This causes the coolant in the cooling water tank that is in contact with this end to boil, thus affecting the efficiency of heat exchange and cooling of the air in the exhaust duct. Therefore, this needs to be improved. Summary of the Invention

[0006] To address the problem that the coolant in the cooling water tank is prone to boiling, which affects the efficiency of heat exchange and cooling of the gas in the air outlet duct, this application provides a water-cooled intercooler.

[0007] The water-cooled intercooler provided in this application adopts the following technical solution:

[0008] A water-cooled intercooler includes an inlet chamber and an outlet chamber opposite to the inlet chamber. The inlet and outlet chambers have openings on opposite sides. A core is disposed between the inlet and outlet chambers. The core includes two side plates and several air ducts. The two side plates are parallel to each other, with one end connected to the inlet chamber and the other end connected to the outlet chamber. Several air ducts are located between the two side plates, are parallel to each other, and are spaced apart horizontally. One end of each air duct communicates with the inlet chamber and the other end communicates with the outlet chamber. A cooling water tank is disposed between adjacent air ducts or between each air duct and a side plate. The cooling water tank is used for heat exchange and cooling of the air ducts. An inlet pipe and an outlet pipe are connected to the cooling water tank. A cooling assembly for cooling the coolant in the cooling water tank is provided within the cooling water tank.

[0009] By adopting the above technical solution, when the high-temperature gas in the intake chamber enters the air duct from one end and flows through it, the high temperature is transferred to the side wall of the air duct, and then to the cooling water tank. The cooling water tank, due to the influence of the coolant, has a lower temperature, allowing heat exchange between the cooling water tank and the air duct, thus lowering the temperature of the air duct. This achieves rapid heat exchange and cooling of the high-temperature gas in the air duct. Finally, the cooled gas enters the exhaust chamber from the other end of the air duct and is discharged. Simultaneously, while the cooling water tank cools the air duct, the cooling components also cool the coolant in the tank, preventing the coolant near the side wall of the tank from boiling and keeping it at a lower temperature, facilitating heat exchange and cooling of the air duct, and improving the efficiency of gas cooling in the air duct.

[0010] Optionally, the cooling assembly includes a motor and a fan. The motor is fixed to the top wall of the cooling water tank, and the output end of the motor extends into the cooling water tank. A ventilation hole is provided through the top wall of the cooling water tank, and a breathable membrane is fixed in the ventilation hole to block coolant from passing through the ventilation hole. The fan is fixed to the inner top wall of the cooling water tank by a mounting bracket and is located below the breathable membrane. The fan is connected to the output end of the motor through a conveyor belt, and the motor is used to drive the conveyor belt to rotate the fan.

[0011] By adopting the above technical solution, when high-temperature gas flows through the air duct, the gas transfers its temperature to the coolant. Air from outside the cooling water tank enters the tank through ventilation holes and a breathable membrane, exchanging heat with the coolant to cool it down. Simultaneously, the motor starts, driving the conveyor belt to rotate the fan, thereby drawing air from the cooling water tank and expelling it through the ventilation holes. This accelerates the rate at which air enters and exits the cooling water tank, and the rapid airflow speeds up the evaporation of the coolant. Since coolant evaporation absorbs heat, it achieves a cooling effect, increasing the rate of coolant cooling and preventing the coolant from boiling at high temperatures. This, in turn, improves the heat exchange and cooling efficiency of the high-temperature gas in the air duct.

[0012] Optionally, an insertion hole is provided on the side wall of the cooling water tank along the length of the vent membrane. The bottom wall of the insertion hole is flush with the top wall of the vent membrane. A movable rod can be inserted into the insertion hole and can move within the insertion hole. A cleaning rod is fixed to one end of the movable rod. The cleaning rod is perpendicular to the movable rod and can pass through the insertion hole.

[0013] By adopting the above technical solution, the cleaning rod is placed horizontally and passes through the insertion hole from the outside of the cooling water tank. Simultaneously, the moving rod is also inserted into the insertion hole. The cleaning rod is moved along its length until it abuts against the inner wall of the ventilation hole. At this point, the moving rod is at one end of the insertion hole. Then, the moving rod is manually driven to move to the other end of the insertion hole, causing the cleaning rod to slide on the inner wall of the ventilation hole and the moving rod to slide on the breathable membrane, thus scraping away impurities from the surface of the breathable membrane. When the moving rod moves to the other end of the insertion hole, the end of the cleaning rod away from the moving rod abuts against the inner end wall of the ventilation hole. At this point, impurities on the breathable membrane are accumulated in the area enclosed by the moving rod, the cleaning rod, and the inner wall of the ventilation hole. Then, the moving rod is moved away from the cooling water tank, i.e., the cleaning rod moves towards the insertion hole on the breathable membrane, causing the cleaning rod to push the impurities on the breathable membrane out of the insertion hole, thereby cleaning the breathable membrane. This prevents impurities from clogging the breathable membrane and thus avoids affecting airflow through it. It facilitates air circulation.

[0014] Optionally, a stirring rod is vertically installed in the cooling water tank, and the output end of the motor is connected to the stirring rod through a connecting rod. The connecting rod is horizontally installed, and the motor is used to drive the connecting rod to rotate the stirring rod around the central axis of the motor.

[0015] By adopting the above technical solution, the motor is started, and the connecting rod drives the stirring rod to rotate around the central axis of the motor. This causes the stirring rod to stir the coolant in the cooling water tank, making the coolant circulate horizontally. That is, the coolant with a higher temperature that is in contact with the inner wall of the cooling water tank moves to the middle of the cooling water tank, while the coolant with a lower temperature in the middle of the cooling water tank moves to the inner wall of the cooling water tank. This achieves the alternation of coolant in the horizontal direction, so that the coolant on the side wall of the cooling water tank is not always at a high temperature, thereby improving the heat exchange efficiency of the cooling water tank for the air duct.

[0016] Optionally, a water pump is connected to the cooling water tank, with the bottom end of the water pump connected to the bottom of the cooling water tank and the top end of the water pump connected to the top of the cooling water tank. A water pump is provided on the water pump, which is used to pump the coolant from the bottom of the cooling water tank to the top of the cooling water tank.

[0017] By adopting the above technical solution, the water pump is started to draw the coolant from the bottom of the cooling water tank into the water pumping pipe and into the top of the cooling water tank, so that the coolant circulates and alternates in the vertical direction. The coolant near the cooling water tank moves away due to the flow, so that the cooling water tank does not exchange heat with the same part of the coolant. That is, the same part of the coolant is not heated to a high temperature, so the coolant is not easy to boil. This keeps the coolant in contact with the cooling water tank at a low temperature, thereby improving the efficiency of cooling the high-temperature gas in the air duct.

[0018] Optionally, the top wall of the cooling water tank is higher than the top wall of the air duct, the liquid level of the coolant in the cooling water tank is flush with the top wall of the air duct, and the top of the water pumping pipe is connected to several nozzles. The nozzles are located above the liquid level of the coolant, and the nozzles are arranged at intervals in the horizontal direction. The range of the nozzles is below the breathable membrane.

[0019] By adopting the above technical solution, when the water pump draws the coolant from the bottom of the cooling water tank into the pump pipe and sprays it out from the nozzles, spraying is achieved. Air enters the cooling water tank through the breathable membrane. Since the coolant immediately encounters the air after being sprayed out, the water molecules fully absorb the heat energy from the air, thus lowering the temperature of the coolant. Furthermore, the simultaneous spraying of coolant from several nozzles, distributed horizontally, ensures that the coolant is sprayed horizontally, thereby increasing the contact area between the sprayed coolant and the air, and thus improving the rate of coolant cooling.

[0020] Optionally, the cooling water tank is fixed with a mounting cover at one end near the air inlet chamber and the other end near the air outlet chamber. The exhaust pipe is located inside the mounting cover. Both the air inlet chamber and the air outlet chamber are provided with a sealing plate for sealing the opening. A connecting hole is opened through the sealing plate. The air duct can be adapted to pass through the connecting hole and communicate with the connecting hole. A mounting ring is fixed on one side of the two sealing plates that are close to each other. The mounting cover can be adapted to be inserted into the mounting ring.

[0021] By adopting the above technical solution, when in use, the high-temperature gas in the intake chamber enters the air duct through the connection hole. The sealing plate blocks other areas of the intake chamber opening, making it difficult for the high-temperature gas in the intake chamber to be discharged from the gap between the intake chamber and the core. The mounting cover is inserted into the mounting ring to realize the positioning and installation of the cooling water tank on the sealing plate, which is convenient to operate.

[0022] Optionally, one side of the air duct abuts against the side wall of the corresponding cooling water tank, and the other side is provided with a plurality of heat dissipation fins. The heat dissipation fins are arranged along the length of the air duct, and the plurality of heat dissipation fins are arranged at intervals in the vertical direction. The side of the heat dissipation fin away from the air duct abuts against the side wall of the adjacent cooling water tank.

[0023] By adopting the above technical solution, one side of the air duct is in direct contact with the cooling water tank. The low-temperature coolant in the cooling water tank transfers the low temperature to the side wall of the cooling water tank, and then the cooling water tank exchanges heat with that side of the air duct to cool it down, thus cooling the air duct and the high-temperature gas inside it. The other side of the air duct is in direct contact with the air, dissipating heat into the air. This side of the air duct is also in contact with the heat sink, transferring some of the high temperature to the heat sink. The heat sink is also in direct contact with the air, thus increasing the contact area between the air duct and the air on that side, facilitating rapid heat dissipation and improving the efficiency of heat exchange and cooling with the air. At the same time, the side of the heat sink away from the air duct is affected by the cooling water tank, so that the heat sink receives heat exchange from both the air and the cooling water tank, resulting in high cooling efficiency for the heat sink and consequently high heat exchange efficiency for the air duct in contact with the heat sink.

[0024] Optionally, the heat sink is arranged in a corrugated pattern.

[0025] By adopting the above technical solution, the corrugated heat sink has a larger contact area with the cooling water tank and the side wall of the air duct compared with the straight heat sink, which results in more temperature being transferred to the heat sink. At the same time, the corrugated heat sink has a larger contact area with the air, which facilitates temperature transfer and thus improves the heat exchange efficiency.

[0026] Optionally, the air duct is provided with a plurality of air guide plates, one end of which is located at one end opening of the air duct and the other end at the other end opening of the air duct. The air guide plates are arranged along the length of the air duct, and the sidewalls of the air guide plates are attached and fixed to the inner wall of the air duct. The plurality of air guide plates are evenly arranged in the vertical direction to divide the air duct into a plurality of air outlet chambers.

[0027] By adopting the above technical solution, the air guide plate divides the gas entering the air duct from the intake chamber into several streams, which then enter the exhaust chamber from their respective exhaust chambers. This prevents the airflow from flowing over a large area in the air duct and causing blockage, thus facilitating gas flow and avoiding insufficient air supply to the engine.

[0028] In summary, this application includes at least one of the following beneficial effects:

[0029] 1. When the high-temperature gas in the intake chamber enters the air duct from one end and flows in the air duct, the high temperature is transferred to the side wall of the air duct, and then transferred to the cooling water tank. The cooling water tank is at a lower temperature due to the influence of the coolant, so the cooling water tank and the air duct exchange heat, thereby reducing the temperature of the air duct. This achieves rapid heat exchange and cooling of the high-temperature gas in the air duct. Finally, the cooled gas enters the exhaust chamber from the other end of the air duct and is discharged.

[0030] 2. When high-temperature gas flows through the air duct, it transfers its temperature to the coolant. Air from outside the cooling water tank enters the tank through the ventilation holes and permeable membrane, exchanging heat with the coolant and thus cooling it. Simultaneously, the motor starts, driving the conveyor belt to rotate the fan, which draws air from the cooling water tank. This air is then expelled through the ventilation holes, accelerating the rate at which air enters and exits the tank. The rapidly flowing air causes the coolant to evaporate faster, and the evaporation of the coolant absorbs heat, achieving a cooling effect. Attached Figure Description

Detailed Implementation

[0040] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0041] This application discloses a water-cooled intercooler. (See also...) Figure 1 and Figure 2 The water-cooled intercooler includes an inlet chamber 10, an outlet chamber 20, and a core 40. The inlet chamber 10 and the outlet chamber 20 are arranged opposite each other in the horizontal direction, and the opposite side of the inlet chamber 10 and the outlet chamber 20 is open. The core 40 is located between the inlet chamber 10 and the outlet chamber 20. The core 40 includes two side plates 41 and several air guide pipes 42. The two side plates 41 are parallel to each other, and one end of the side plate 41 is connected to the inlet chamber 10 through a sealing plate 30. The other end of the side plate 41 is also connected to the outlet chamber 20 through a sealing plate 30. The two ends of the side plate 41 are respectively fixed to the corresponding sealing plates 30. The sealing plate 30 located at the inlet chamber 10 blocks the opening of the inlet chamber 10 and is fixed to the inlet chamber 10. The sealing plate 30 located at the outlet chamber 20 blocks the opening of the outlet chamber 20 and is fixed to the outlet chamber 20.

[0042] Reference Figure 1 and Figure 2Several air ducts 42 are located within the area enclosed by two side plates 41 and two sealing plates 30. The air ducts 42 are parallel to each other and spaced apart in the horizontal direction. Several connecting holes 31 are provided through the side wall of the sealing plate 30. Each air duct 42 corresponds to one connecting hole 31. One end of the air duct 42 is inserted into the connecting hole 31 on one of the sealing plates 30 and communicates with the connecting hole 31. The other end of the air duct 42 is inserted into the connecting hole 31 on the other sealing plate 30 and communicates with the connecting hole 31. Thus, one end of the air duct 42 is connected to the air inlet chamber 10 and the other end is connected to the air outlet chamber 20. The direction from the air inlet chamber 10 to the air outlet chamber 20 is defined as the length direction of the air duct 42, while the direction perpendicular to the length direction of the air duct 42 in the horizontal direction is defined as the width direction of the air duct 42.

[0043] In use, the high-temperature gas in the intake chamber 10 enters the air duct 42 through the connection hole 31. The sealing plate 30 blocks other areas of the opening of the intake chamber 10, making it difficult for the high-temperature gas in the intake chamber 10 to be discharged from the gap between the intake chamber 10 and the core 40. The gas in the air duct 42 will flow towards the exhaust chamber 20, and then be discharged from the air duct 42 and enter the exhaust chamber 20 through the connection hole 31 on the sealing plate 30 connected to the exhaust chamber 20, and finally be discharged from the exhaust chamber 20.

[0044] Reference Figure 2 and Figure 3 To prevent airflow from flowing excessively in the air duct 42 and causing blockage, thus avoiding insufficient air supply to the engine, several air guide plates 421 are provided in the air duct 42. The air guide plates 421 are arranged along the length of the air duct 42, with one end extending to the opening at one end of the air duct 42 and the other end extending to the opening at the other end of the air duct 42. The air guide plates 421 are arranged at intervals in the vertical direction and are placed horizontally. The sidewalls of the air guide plates 421 are attached and fixed to the inner wall of the air duct 42, thereby dividing the air duct 42 into several air outlet chambers distributed in the vertical direction. This allows the gas entering the air duct 42 from the air intake chamber 10 to be divided into several streams and enter the air outlet chamber 20 from the corresponding air outlet chambers, preventing the airflow from flowing excessively in the air duct 42 and causing blockage.

[0045] Reference Figure 2 and Figure 3To reduce the temperature of the gas in the air duct 42, a cooling water tank 50 storing coolant is installed between adjacent air ducts 42 or between the air duct 42 and the side wall. The cooling water tank 50 is arranged along the length of the air duct 42, and the length of the cooling water tank 50 is less than the length of the air duct 42. That is, the length direction of the cooling water tank 50 is the length direction of the air duct 42. Mounting covers 53 are fixed at both ends of the length direction of the cooling water tank 50. Several mounting rings 32 are fixed on the side of the sealing plate 30 near the side plate 41. Each cooling water tank 50 corresponds to one mounting ring 32. The mounting cover 53 can be inserted into the corresponding mounting ring 32 to realize the installation of the cooling water tank 50 on the sealing plate 30.

[0046] Reference Figure 2 and Figure 3 A water inlet pipe 51 is fixed on the top wall of the cooling water tank 50, and the water inlet pipe 51 is connected to the cooling water tank 50. A water outlet pipe 52 is fixed on the bottom wall of the cooling water tank 50, and the water outlet pipe 52 is also connected to the cooling water tank 50. Coolant can enter the cooling water tank 50 from the water inlet pipe 51 and can also be discharged from the cooling water tank 50 from the water outlet pipe 52 to realize the replacement of coolant. During use, when gas is introduced into the air duct 42 from the air inlet chamber 10 and then into the air outlet chamber 20 from the air duct 42, both the water inlet pipe 51 and the water outlet pipe 52 are in a closed state.

[0047] Reference Figure 2 and Figure 3 One side of the air duct 42 along its length is attached to the side wall of the adjacent cooling water tank 50, and a number of heat sinks 140 are fixed on the other side. The heat sinks 140 are arranged along the length of the air duct 42 and are spaced apart in the vertical direction. The cross section of the heat sink 140 along its length is corrugated. The side of the heat sink 140 away from the air duct 42 is attached to the side wall of the corresponding cooling water tank 50.

[0048] When the high-temperature gas flows through the air duct 42, it transfers its high temperature to the side wall of the duct 42. One side of the air duct 42 is in direct contact with the cooling water tank 50. The low-temperature coolant in the cooling water tank 50 transfers its low temperature to the side wall of the cooling water tank 50, and then the cooling water tank 50 exchanges heat with this side of the air duct 42 to cool it down, thus cooling the high-temperature gas inside the air duct 42. The other side of the air duct 42 is in direct contact with the air, dissipating heat into the air. This side of the air duct 42 is also in contact with the heat sink 140, transferring some of the high temperature to the heat sink 140. The heat sink 140 is also in direct contact with the air, thus increasing the contact area between this side of the air duct 42 and the air, facilitating the rapid dissipation of heat and improving the efficiency of heat exchange and cooling with the air. Meanwhile, the side of the heat sink 140 away from the air duct 42 is affected by the cooling water tank 50, so that the heat sink 140 has heat exchange with both air and cooling water tank 50, which makes the cooling efficiency of the heat sink 140 high, and thus the heat exchange efficiency of the air duct 42 in contact with the heat sink 140 high.

[0049] Reference Figure 3 The corrugated shape of the heat sink 140 increases the contact area between the heat sink 140 and the side wall of the cooling water tank 50 and the air duct 42, resulting in more heat being transferred to the heat sink 140. At the same time, the corrugated heat sink 140 has a larger contact area with the air, which facilitates heat transfer and thus improves the heat exchange efficiency.

[0050] Reference Figure 4 and Figure 5 The high-temperature gas in the air duct 42 transfers the high temperature to the cooling water tank 50, which easily heats the coolant. To prevent the coolant from boiling, a cooling component 60 is provided in the cooling water tank 50 to reduce the coolant temperature. The top wall of the cooling water tank 50 is higher than the top wall of the air duct 42, and the level of the coolant in the cooling water tank 50 is flush with the top wall of the air duct 42, so that the parts of the cooling water tank 50 in contact with the air duct 42 are cooled by coolant.

[0051] Reference Figure 4 and Figure 6 The cooling assembly 60 includes a motor 61 and a fan 62. The motor 61 is fixed to the top wall of the cooling water tank 50 by bolts. The output end of the motor 61 extends vertically downward and through the top wall of the cooling water tank 50 into the cooling water tank 50. The fan 62 is fixedly installed on the inner top wall of the cooling water tank 50 by a mounting bracket 621. The fan 62 is located above the surface of the coolant. The shaft of the fan 62 is connected to the output end of the motor 61 through a conveyor belt 63.

[0052] Reference Figure 6 and Figure 7The conveyor belt 63 includes a drive wheel 631, a driven wheel 632, and a belt 633. The drive wheel 631 is coaxially fixed on the output end of the motor 61, and the driven wheel 632 is coaxially fixed on the rotating shaft of the fan 62. The belt 633 is sleeved on the drive wheel 631 and the driven wheel 632. When the drive wheel 631 rotates, it can drive the belt 633 to move, causing the driven wheel 632 to rotate.

[0053] Reference Figure 4 A ventilation hole 54 is provided on the top wall of the cooling water tank 50, and a breathable membrane 70 is provided in the ventilation hole 54. In this embodiment, the breathable membrane 70 is an expanded polytetrafluoroethylene waterproof and breathable membrane 70. The breathable membrane 70 is horizontally arranged, and the circumferential sidewall of the breathable membrane 70 is attached and fixed to the inner wall of the ventilation hole 54 to block the coolant from passing through the ventilation hole 54. The fan 62 is located below the breathable membrane 70.

[0054] When high-temperature gas flows through the air duct 42, it transfers its temperature to the coolant. Air from outside the cooling water tank 50 enters the tank through the ventilation hole 54 and the breathable membrane 70, exchanging heat with the coolant to cool it down. Simultaneously, the motor 61 starts, driving the drive wheel 631 to move the belt 633, causing the driven wheel 632 to drive the fan 62 to rotate synchronously. This draws air from the cooling water tank 50, causing it to exit through the ventilation hole 54. This accelerates the rate at which air enters and exits the cooling water tank 50, leading to faster evaporation of the coolant. The rapid airflow increases the evaporation rate of the coolant, which absorbs heat during evaporation, achieving a cooling effect. This increases the cooling rate of the coolant, making it less prone to boiling at high temperatures, thus improving the heat exchange and cooling efficiency of the high-temperature gas in the air duct 42.

[0055] Reference Figure 8 In order to regularly clean the impurities on the upper surface of the breathable membrane 70 and prevent the impurities from clogging the gaps on the breathable membrane 70 for a long time and affecting the passage of air, an insertion hole 55 is provided on the side wall of the cooling water tank 50 along the length of the cooling water tank 50. The bottom wall of the insertion hole 55 is flush with the top wall of the breathable membrane 70. A movable rod 80 can be inserted into the insertion hole 55 and can move in the insertion hole 55. A cleaning rod 81 is fixed to one end of the movable rod 80. The cleaning rod 81 is perpendicular to the movable rod 80 and can also pass through the insertion hole 55.

[0056] Place the cleaning rod 81 horizontally and pass it through the insertion hole 55 from the outside of the cooling water tank 50. At the same time, insert the moving rod 80 into the insertion hole 55. Move the cleaning rod 81 along the length of the moving rod 80 until the cleaning rod 81 abuts against the inner wall of the ventilation hole 54. At this time, the moving rod 80 is located at one end of the insertion hole 55. Then, manually drive the moving rod 80 to move to the other end of the insertion hole 55, so that the cleaning rod 81 slides on the inner wall of the ventilation hole 54 and the moving rod 80 slides on the breathable membrane 70, thereby cleaning the impurities on the upper surface of the breathable membrane 70. When the moving rod 80 moves to the other end of the socket 55, the end of the cleaning rod 81 away from the moving rod 80 abuts against the inner end wall of the ventilation hole 54. At this time, impurities on the breathable membrane 70 are accumulated in the area enclosed by the moving rod 80, the cleaning rod 81, and the inner wall of the ventilation hole 54. Then, the moving rod 80 moves away from the cooling water tank 50, that is, the cleaning rod 81 moves towards the socket 55 on the breathable membrane 70, so that the cleaning rod 81 pushes the impurities on the breathable membrane 70 out of the socket 55, thereby cleaning the breathable membrane 70. This makes it less likely for impurities to accumulate on the breathable membrane 70 and clog it, thus not affecting the airflow through the breathable membrane 70. This facilitates air circulation.

[0057] Reference Figure 4 and Figure 7 In order to further improve the efficiency of heat exchange between the coolant and the air duct 42 while the fan 62 is drawing air, a connecting rod 90 is fixedly connected to the output end of the motor 61. The connecting rod 90 is horizontally set in the cooling water tank 50. A stirring rod 110 is fixed to the end of the connecting rod 90 away from the output end of the motor 61. The stirring rod 110 is vertically set and its bottom end extends to the bottom of the cooling water tank 50. The stirring rod 110 can rotate in the cooling water tank 50 about the central axis of the motor 61.

[0058] When the motor 61 starts, the drive connecting rod 90 drives the stirring rod 110 to rotate around the central axis of the motor 61. This causes the stirring rod 110 to stir the coolant in the cooling water tank 50, making the coolant circulate horizontally. The coolant with a higher temperature that is in contact with the inner wall of the cooling water tank 50 is moved to the middle of the cooling water tank 50, while the coolant with a lower temperature in the middle of the cooling water tank 50 is moved to the inner wall of the cooling water tank 50. This horizontal alternation of coolant prevents the coolant on the side wall of the cooling water tank 50 from being at a high temperature all the time, thereby improving the heat exchange efficiency of the cooling water tank 50 to the air duct 42.

[0059] Reference Figure 4 and Figure 6To improve the cooling efficiency of the coolant when the fan 62 is drawing air, a water suction pipe 130 is installed inside the mounting cover 53. One end of the water suction pipe 130 is connected to the bottom of the cooling water tank 50, and the other end is connected to the top of the cooling water tank 50. A water pump 120 is installed on the water suction pipe 130 to draw the coolant from the bottom of the cooling water tank to the top of the cooling water tank 50. Several nozzles 131 are connected to the top of the water suction pipe 130. The nozzles 131 are arranged at intervals along the width of the cooling water tank 50, and are positioned above the surface of the coolant. The range of the nozzles 131 is below the fan 62.

[0060] Start the water pump 120 to draw the coolant from the bottom of the cooling water tank 50 into the water pump pipe 130 and into the top of the cooling water tank 50, so that the coolant circulates and alternates in the vertical direction. The coolant near the cooling water tank 50 is moved away due to the flow, so that the cooling water tank 50 does not exchange heat with the same part of the coolant. That is, the same part of the coolant is not heated at a high temperature, so the coolant is not easy to boil, and the coolant in contact with the cooling water tank 50 always maintains a low temperature.

[0061] Reference Figure 4 and Figure 6 The coolant drawn into the water intake pipe 130 is eventually sprayed out by the nozzles 131, achieving spraying. Air enters the cooling water tank 50 through the breathable membrane 70. Since the coolant immediately encounters the air after being sprayed out, the water molecules fully absorb the heat energy from the air, thus lowering the temperature of the coolant. The simultaneous spraying of coolant from several nozzles 131, distributed horizontally, increases the contact area between the sprayed coolant and the air, improving the cooling rate and thus increasing the efficiency of cooling the high-temperature gas in the air duct 42.

[0062] The implementation principle of a water-cooled intercooler in this application embodiment is as follows: By adopting the above technical solution, when the high-temperature gas in the intake chamber 10 enters the air duct 42 from one end of the air duct 42 and flows in the air duct 42, the high temperature is transferred to the side wall of the air duct 42, and then transferred to the cooling water tank 50 by the air duct 42. The cooling water tank 50 has a lower temperature due to the influence of the coolant, so that the cooling water tank 50 and the air duct 42 exchange heat, thereby reducing the temperature of the air duct 42, thereby achieving rapid heat exchange and cooling of the high-temperature gas in the air duct 42. Finally, the cooled gas enters the exhaust chamber 20 from the other end of the air duct 42 and is discharged.

[0063] While the cooling water tank 50 cools the air duct 42, the motor 61 is started, driving the conveyor belt 63 to rotate the fan 62, thereby drawing air out of the cooling water tank 50. The air in the cooling water tank 50 is then discharged through the ventilation hole 54, which accelerates the rate at which air enters and exits the cooling water tank 50. The rapidly flowing air causes the coolant to evaporate faster, and the evaporation of the coolant absorbs heat, achieving a cooling effect. This increases the rate at which the coolant cools down, making it less likely for the coolant to boil at high temperatures, thus improving the heat exchange and cooling efficiency of the high-temperature gas in the air duct 42.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
