Description
Technical Field
[0001] The utility model belongs to the field of air supply cooling, and in particular relates to a novel gas engine intercooler with an automatic drainage device. Background Art
[0002] For turbocharged engines, the intercooler is an important component of the turbocharging system. The intercooler needs to be arranged between the supercharger and the engine intake pipe. The intercooler is used to cool the high-temperature air after being pressurized by the supercharger and cool it to 40-60℃.
[0003] When vehicles equipped with turbocharged engines are running in relatively humid environments such as southern my country, the air inhaled by the engine is cooled by the intercooler, and the water vapor in the air condenses into liquid water. A part of the condensed water is brought into the engine cylinder under the action of the supercharged airflow, affecting the combustion effect of the fuel and thus the engine power performance. In addition, most of the liquid water also exists in the intercooler outlet pipe or the engine intake pipe, and enters the cylinder when the engine is shut down. The water will accumulate on the top of the piston, reducing the effective volume of the combustion chamber, increasing the compression resistance, and increasing the pressure transmitted to the connecting rod by the piston. When the amount of accumulated water reaches a certain level, the compression stroke actually becomes a compression of the water, and the pressure on the connecting rod increases sharply, causing bending and deformation, or even breaking, which seriously affects the service life of the engine.
[0004] Because the technical route of the National VI gas engine is a closed cycle, according to the combustion characteristics of the gas engine, the intake pipe of the gas engine is more likely to produce condensed water than that of the conventional fuel engine. The water will accumulate at the bottom of the intercooler in large quantities. Because the accumulated water enters the engine cylinder along the intake pipe, it causes the engine to have problems such as water accumulation at the head of the ignition coil, engine misfire, and insufficient power. In addition, in the cold winter, the liquid water at the bottom of the intercooler is not effectively discharged in time, which can easily cause the liquid water at the bottom of the intercooler to freeze. In severe cases, it causes the expansion tube of the lower heat dissipation pipe of the intercooler to burst, and the intake volume leaks and causes the engine power to drop. Therefore, timely discharge of liquid water can effectively reduce the above hidden dangers. At present, most vehicles on the market have installed a drain valve or drain plug at the bottom of the intercooler. When the condensed water at the bottom of the intercooler reaches a certain amount, manually unscrew the drain valve to discharge the condensed water at the bottom of the intercooler to avoid engine failures caused by excessive condensed water.
[0005] Because the drain valve or drain plug is installed at the bottom of the intercooler, the user needs to manually drain the water regularly, which is inconvenient for the user. If the drain cycle is not properly controlled, it is easy to cause engine failure. There is also a solution of opening a permanent hole at the bottom of the intercooler. This solution can drain the liquid water in time, but the permanent hole will cause a loss of 20-30N·m in engine power, affecting the power performance of the whole vehicle. In addition, in the cold winter, the condensed water at the bottom of the intercooler is easy to freeze, resulting in the drain valve cannot be manually unscrewed, the drain hole is blocked, and the accumulated water cannot be discharged, causing engine failure.
[0006] Therefore, how to optimize the structure of the intercooler itself so that liquid water can be automatically discharged and the problem of freezing in winter is a technical problem that needs to be solved urgently in this field. Utility Model Content

[0012] Furthermore, the heat dissipation core includes an air intake side main plate, a heat dissipation pipe, a heat dissipation belt and an air outlet side main plate. A plurality of heat dissipation pipes are provided, and the plurality of heat dissipation pipes are connected between the air intake side main plate and the air outlet side main plate. The heat dissipation pipes are connected with heat dissipation belts, and the heat dissipation belts include high-efficiency heat dissipation belts and low-efficiency heat dissipation belts. The high-efficiency heat dissipation belts are arranged in the high-efficiency heat dissipation zone and the medium heat dissipation zone, and the low-efficiency heat dissipation belts are arranged in the low-efficiency heat dissipation zone.
[0013] Furthermore, the two ends of the heat dissipation pipe are respectively connected to the main plate on the air inlet side and the main plate on the air outlet side, and the heat dissipation pipe includes a V-shaped high-efficiency heat dissipation pipe located in the high-efficiency heat dissipation area, a high-resistance-high-efficiency heat dissipation pipe located in the medium radiator, and a low-resistance-low-efficiency heat dissipation pipe located in the low-efficiency heat dissipation area; the V-shaped high-efficiency heat dissipation pipe is provided with a V-shaped internal gear plate inside;

The 10 tubes in the middle part of the core are high resistance-high efficiency heat dissipation tubes, and the internal tooth plates therein adopt the first S-shaped internal tooth plates with convex points on the surface of the internal tooth plates with a wave height of 7mm and a wave pitch of 5.5mm; the 6 tubes at the lower part of the intercooler are low resistance-low efficiency heat dissipation tubes 3, and the internal tooth plates therein adopt the second S-shaped internal tooth plates with a wave height of 7mm and a wave pitch of 5.5mm.

The 32 heat dissipation belts are connected to 32 heat dissipation pipes by welding. Because the wave pitch of the heat dissipation belt in the lower area is greater than that in the upper area, the heat dissipation area of the lower area is reduced, the heat dissipation efficiency is reduced, and the corresponding lower air temperature on the outlet side is higher than the upper air temperature. Different inner teeth are provided in the 32 heat dissipation pipes, among which the efficiency and resistance of the V-shaped inner teeth are higher than those of the first S-shaped inner teeth and the second S-shaped inner teeth, the efficiency and resistance of the first S-shaped inner teeth with dots on the surface are higher than those of the second S-shaped inner teeth without dots, and the heat dissipation belt with a wave pitch of 5.5mm has a larger unfolded heat dissipation area than the heat dissipation belt with a wave pitch of 8mm.

The air flow rate in the lower area of the intercooler is lower than that in the upper area, and the design of the partition in the intercooler air outlet chamber can reduce the liquid water on the air chamber wall attached to the intake air and enter the engine cylinder, which can promote the condensed water in the intercooler air outlet chamber to gather at the bottom of the air chamber under the action of gravity and enter the automatic drainage device.
[0016] Furthermore, the intercooler air inlet chamber and the intercooler air outlet chamber adopt an offset L-shaped structure that is not symmetrical up and down, and its design can adjust the flow field distribution inside the intercooler and reduce the air flow rate in the lower part of the air chamber. The upper end of the intercooler air inlet chamber is designed with an intercooler air inlet for connecting the intercooler air inlet pipeline after the engine is supercharged. The upper end of the intercooler air outlet chamber is designed with an intercooler air outlet for connecting the engine air intake pipeline. The bottom of the intercooler air outlet chamber is designed with a through hole for connecting the automatic drainage device, and a partition is provided inside the intercooler air outlet chamber. The middle part of the intercooler air outlet chamber is designed with a partition with a width of about 10 mm on the surface of the air chamber wall, which can effectively reduce the liquid water on the air chamber wall attached to the intake air and enter the engine cylinder body, and can promote the condensed water in the intercooler air outlet chamber to gather at the bottom of the air chamber under the action of gravity and enter the automatic drainage device.
[0017] Furthermore, the automatic drainage device includes a drainage component, an O-ring, an outlet pipe and a worm clamp.

The middle part of the drainage component is designed as a hexagonal head structure for the installation and disassembly of the automatic drainage device.
[0018] Furthermore, the drainage assembly includes an outer shell, a float, a valve stem, a retaining ring, a filter and a spring; the interior of the outer shell includes a storage chamber located at the top and a working chamber located at the bottom, the storage chamber and the working chamber are connected, a filter and a retaining ring are arranged between the working chamber and the storage chamber, the retaining ring is used to limit the filter, and the valve stem passes through the filter; the working chamber is provided with an inclined surface that is larger at the top and smaller at the bottom, the valve stem is provided with a matching inclined surface that matches the working chamber, the spring is located in the working chamber, the bottom of the spring abuts against the working chamber, one end of the valve stem abuts against the spring, and the other end of the valve stem is connected to a float.

[0019] Beneficial effects of the utility model:
[0020] 1. The heat dissipation core of the utility model is composed of a high-efficiency heat dissipation pipe at the top, a high-resistance and high-efficiency heat dissipation pipe at the middle, a low-resistance and low-efficiency heat dissipation pipe at the bottom, a heat dissipation belt with a wave height of 12mm and a wave pitch of 5.5mm at the top and middle of the intercooler core, and a heat dissipation belt with a wave height of 12mm and a wave pitch of 8mm at the bottom. The combined heat dissipation core structure is adopted, the S-shaped inner tooth plate at the bottom has a larger wave pitch than the V-shaped inner tooth plate at the top, and the heat dissipation belt at the bottom has a larger wave pitch than the heat dissipation belt at the top. Therefore, the heat dissipation efficiency of the S-shaped inner tooth plate heat dissipation pipe at the bottom is low, so the temperature at the bottom of the heat dissipation core is higher than that at the top, that is, the air temperature at the bottom of the air outlet chamber is higher than that at the top, which can solve the technical problem of condensed water freezing at the bottom of the air outlet chamber in winter.
[0021] 2. The air inlet and outlet on the air inlet chamber and the air outlet chamber of the utility model adopt an offset design scheme, so the upper part of the intercooler is a high-flow area and the lower part is a low-speed area. Secondly, the design of the inner teeth with dots on the S-shaped surface in the middle can increase the air intake resistance of the heat dissipation pipe in the middle of the core, and further reduce the air flow in the middle area of the core. Under the design of the inner teeth of the radiator and the offset scheme of the air inlet and outlet, the middle and bottom of the core can be ensured to be low-flow areas, and the condensed water inside the intercooler can be gathered at the bottom of the air chamber under the action of gravity as much as possible, reducing the water content of the intake air brought into the engine cylinder.
[0022] 3. The automatic drainage device of the utility model is arranged at the bottom of the air outlet chamber and is installed with threaded connection, which is easy to assemble; at the same time, it can automatically drain water according to the water content at the bottom of the intercooler, which can solve the power loss problem caused by the regular through hole, and is economical and practical; at the same time, it saves manual drainage operation, saves labor and is easy to maintain, and has a simple structure.
[0023] 4. The intercooler of the utility model is designed with an automatic drainage device, which can open the drainage hole after the vehicle is turned off and parked to completely drain the liquid water inside the intercooler. After the vehicle is started, the drainage hole can be opened in time to drain the liquid water according to the water storage at the bottom of the air chamber, solving the power loss problem caused by the usual drainage hole and improving the power performance of the whole vehicle.

[0051] The low resistance and low efficiency heat dissipation pipe has a second S-shaped inner tooth plate 2231 disposed inside the low resistance portion.
[0052] The heat dissipation core 2 is mainly composed of 32 heat dissipation tubes 22, among which the 16 on the upper part of the heat dissipation core 2 are V-shaped high-efficiency heat dissipation tubes 221, and the internal gear pieces therein adopt V-shaped internal gear pieces 2211 with a wave height of 7mm and a wave pitch of 4mm and a window; the 10 in the middle part of the core are high-resistance and high-efficiency heat dissipation tubes 222, and the internal gear pieces therein adopt the first S-shaped internal gear pieces 2221 with a wave height of 7mm, a wave pitch of 5.5mm, and convex dots on the surface of the internal gear pieces; the 6 at the lower part of the intercooler are low-resistance and low-efficiency heat dissipation tubes 223, and the internal gear pieces therein adopt the second S-shaped internal gear pieces 2231 with a wave height of 7mm and a wave pitch of 5.5mm.

The 32 heat dissipation belts 23 are connected to the 32 heat dissipation pipes 22 through a welding process. Because the wave pitch of the heat dissipation belts 23 in the lower area is greater than that in the upper area, the heat dissipation area in the lower area is reduced, the heat dissipation efficiency is reduced, and the corresponding lower air temperature on the outlet side is higher than the upper air temperature.

[0055] The heat dissipation efficiency of the lower area of the intercooler is lower than that of the upper area, which can ensure that the air temperature at the bottom of the intercooler outlet chamber 3 is relatively high, and can solve the technical problem of condensed water freezing at the bottom of the outlet chamber in winter. The air flow rate in the lower area of the intercooler is lower than that in the upper area, and the design of the partition plate 33 in the intercooler outlet chamber 3 can reduce the liquid water on the air chamber wall adhering to the intake air and entering the engine cylinder body, which can promote the condensed water in the intercooler outlet chamber 3 to gather at the bottom of the air chamber under the action of gravity and enter the automatic drainage device 4.

The function of the worm clamp 43 is to clamp the outlet pipe 44 to prevent it from falling off. The middle part of the drain assembly 41 is designed as a hexagonal head structure for the installation and removal of the automatic drain device 4.
[0063] Embodiment 5:
[0064] Based on the embodiment 4, the drainage assembly 41 includes an outer shell 411, a float 412, a valve stem 413, a retaining ring 414, a filter screen 415 and a spring 416;
[0065] The interior of the outer shell 411 includes a storage chamber 417 located at the upper part and a working chamber located at the lower part (the storage chamber 417 and the working chamber are actually one chamber, but are given two names for the convenience of description). The storage chamber 417 and the working chamber are connected. A filter screen 415 and a retaining ring 414 are provided between the working chamber and the storage chamber 417. The retaining ring 414 is used to limit the filter screen 415. The valve stem 413 passes through the filter screen 415.
[0066] The working chamber is provided with an inclined surface 4111 which is larger at the top and smaller at the bottom, the valve stem 413 is provided with a matching inclined surface 4131 which is adapted to the working chamber, the spring 416 is located in the working chamber, the bottom of the spring 416 abuts against the working chamber, one end of the valve stem 413 abuts against the spring 416, and the other end of the valve stem 413 is connected to the float 412.
[0067] The inner surface of the working chamber of the outer shell 411 is designed to be a tapered inclined surface 4111 which is larger at the top and smaller at the bottom. The working surface 4132 of the valve stem 413 is also designed to be a matching tapered inclined surface 4131 which is larger at the top and smaller at the bottom. The surface of the filter screen 415 is designed with a φ2mm through hole 32, which is fixed to the bottom of the storage chamber 417 under the limit of the retaining ring 414.
[0068] Here’s how it works:
[0069] During the parking process of the vehicle, the valve stem 413 moves upward under the action of the spring 416. During the upward movement, the gap between the valve stem 413 and the outer shell 411 gradually increases, and the liquid water in the intercooler outlet chamber 3 is discharged from the storage chamber 417 through the gap between the valve stem 413 and the outer shell 411.
[0070] After the vehicle is started, the pressure in the intercooler outlet chamber 3 increases, causing the pressure in the storage chamber 417 to increase synchronously. The working surface 4132 of the valve stem 413 moves downward under the action of pressure until the valve stem 413 is sealed with the outer shell. At the same time, the spring 416 is compressed and the drainage chamber 4112 is closed.
[0071] During vehicle operation, liquid water in the intercooler outlet chamber 3 gradually gathers in the storage chamber 417 in the drainage device 4 under the action of gravity. When the working conditions of the float 412 are met (the amount of water is sufficient and the buoyancy is large enough), the float 412 floats up and drives the valve stem 413 to move upward under the action of the spring 416. During the upward movement, the gap between the valve stem 413 and the outer shell 411 gradually increases, and the liquid water in the intercooler outlet chamber 3 is discharged from the gap between the storage chamber 417 and the valve stem 413. When the liquid water is completely discharged from the storage chamber 417, the working surface 4132 of the valve stem 413 moves downward under the action of pressure until it is sealed with the working surface 4132. At the same time, the spring 416 is compressed and the drainage chamber 4112 is closed, which solves the problem of engine power loss caused by air intake leakage and improves the power performance of the whole vehicle.

However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
