Description

  The present invention relates to a cooling device for cooling an intake system piping portion around an intercooler, an intake system piping cooling system, and the like.

An engine with a turbocharger is installed to increase the engine output by pressurizing the intake air with a turbocharger compressor. However, the intake air is heated by the turbocharger compressor at the same time and becomes hot and is supplied to the engine. Since the temperature is too high, an intercooler is attached to the intake system piping, and the running ram pressure wind is applied to this to cool the intake air and supply it to the engine.
The traveling ram pressure wind refers to the wind that is taken in from the air intake when the vehicle is traveling.

  In general, when the outside air temperature is about 20 ° C, the intake air temperature at the entrance to the intercooler body from the turbocharger is 130 ° C or higher during severe use of the engine, and the temperature during normal use is around 70 ° C to 90 ° C. In contrast, the maximum temperature of the outlet portion, which is cooled by the intercooler in response to the traveling ram pressure wind from the front, is about 60 ° C. or lower, and the normal temperature is cooled to about 40 ° C. to 50 ° C. It is explained.

  When an intercooler is mounted on a turbocharged engine, the conventional installation location is roughly divided into two types with respect to the engine. One is a type that has a radiator in front of the engine and an intercooler is arranged in front of the radiator (hereinafter referred to as a radiator front arrangement type), and the other is a radiator in front of the engine, This is a type in which an intercooler is arranged above the engine (hereinafter referred to as a radiator rear arrangement type).

  In the radiator front arrangement type, there is a radiator in front of the turbocharged engine, an intercooler is arranged in front of the radiator, and the intake air is pressurized by the turbocharger compressor through the air cleaner and heated at the same time. The first intake hose enters the intercooler disposed in front of the radiator and is cooled by the traveling ram pressure wind taken from the front of the vehicle.

  In addition, in the rear arrangement type of the radiator, there is a radiator in front of the engine with a supercharger, an intercooler is arranged above the engine, the intake air is pressurized by the supercharger compressor through the air cleaner, and at the same time It is heated and enters the intercooler above the engine by the first intake hose, and is cooled by the traveling ram pressure air taken from the bonnet air intake above this.

  However, in the radiator front arrangement type, the hose continues from the intercooler body through the side of the radiator through the side of the radiator by the next second intake hose through the side of the engine to the throttle valve at the back, Because of the close proximity to the heat source of about 80 ° C. coming from the radiator and engine, the second intake hose is always heated to a high temperature of about 80 ° C. As a result, the intake air cooled by the intercooler main body is heated again here and reaches a high temperature of about 65 ° C. or higher and is supplied to the engine.

  In addition, in the rear arrangement type of the radiator, all the intake system piping including the intercooler above the engine is always heated by the heat source of about 80 ° C. coming from the radiator and the engine, and taken from the bonnet air intake above. The core part of the intercooler body is gradually cooled by the traveling of the car by the traveling ram pressure wind, but the subsequent outlet chamber and the second intake hose are not cooled and are close to the heat source, so that they are heated at any time. The temperature is close to ℃. As a result, the intake air cooled by the intercooler main body is heated again here and reaches a high temperature of about 65 ° C. or higher and is supplied to the engine.

  In addition, when the vehicle is running at low speed or when the vehicle is stopped, the cooling capacity of the intercooler decreases because the ram pressure wind is weak or absent, and all of the intake system piping is immediately affected by the heat source of about 80 ° C from the radiator and engine. It is heated and becomes a high temperature of about 70 ° C. or higher. As a result, the intake air is supplied to the engine at a high temperature without being cooled.

  In addition, when the vehicle starts running while it is stopped, all of the intake system piping has already been heated by the radiator and engine heat sources, and the temperature is close to 80 ° C. Cooling begins, but after that, the outlet chamber and the piping of the second intake hose are once cooled down and continue to run at a medium high speed. However, the high temperature state will continue for a long time.

  Therefore, there is an “intercooler fresh air introduction structure” described in Utility Model No. 2563482 as a cooling device that is devised to actively lower the intake air temperature of the engine. In the engine with a supercharger described in this utility model No. 2563482, as shown in FIG. 9 and FIG. 10, an automobile having an engine installed at the center or rear part of the vehicle body is used as an intake system. The intervening air-cooled intercooler 101 is in the vicinity of the engine 110, and the intake system piping path is supplied from the air cleaner 105 to the intercooler 101 via the supercharger compressor 106 and the first intake hose 107, and further the second intake hose 103. The engine 110 is supplied to the engine 110 through the throttle valve 104 and the intake manifold 109.

  In order to cool the intercooler 101 with the traveling ram pressure 119, it passes through a fresh air introduction path 120 including a side member 113 connected to a fresh air intake 112 provided in the automobile front bumper 111, and is newly provided by a fresh air introduction duct 114. The entire intercooler 101 is attached in a covered structure.

  Furthermore, an intercooler fresh air introduction structure is provided in which an electric motor fan 115 is attached to the rear surface of the intercooler 101 and the intercooler 101 is cooled by control by an engine control signal.

  However, in the intake system piping concentrated in the high temperature engine room, even if the intake air is actively cooled by the electric motor fan 115 in the intercooler body 101 portion, it is next to the intercooler body 101 cooling core portion. The outlet chamber 102 and the slightly longer second intake hose 103 piped from the outlet chamber 102 are not cooled because they are close to the engine 110, and are always heated by receiving heat of about 80 ° C. Therefore, the intake air again becomes a high temperature of 65 ° C. or higher even if estimated to be low in this portion, and is supplied to the engine 110 via the throttle valve 104.

  If the intake system piping cooling device of the present invention is described with reference to another embodiment shown in FIG. 4, this automobile is a vehicle of a radiator front arrangement type, and a radiator 14 is arranged in front of the engine 10. The intercooler main body 1 is installed in front of the radiator 14.

  The configuration of each part is that a turbocharger is arranged in the exhaust manifold 16 of the exhaust system in front of the engine 10, exhaust pipe & muffler 18 pipes are arranged on the right side from the turbocharger turbine 17, and the engine 10 is in the rear of the engine 10. There is an intake system pipe supplied to the throttle valve 4, the surge tank 8, the intake manifold 9 and the engine 10.

The intake system piping cooling apparatus of the present invention shown in FIG. 4 includes an air intake port 11, a relay duct 12, and a cooling cover 13, each of which includes pipe-shaped parts, such as a PVC thin-walled pipe, an aluminum flexible pipe, Manufactured using thin aluminum sheets.
The air intake 11 is fixed to the side of the outlet chamber 2 of the intercooler body 1 in front of the radiator 14, and the second intake hose 3 having a curved curve is wrapped with a relay duct 12, and the throttle valve 4 in front of the rear of the second intake hose 3 is in front. These components are wrapped in a cooling cover 13 and are connected together.

  The installation of the intake pipe cooling device of the present invention shown in FIG. 4 will be described. First, using the air intake port 11 as a φ150-φ100 PVC paragraph, the φ100 side is used as a connection to the relay duct 12 and the φ100 salt. About 40 mm of pipe pipe is put out and bonded, and the side on the φ150 side is cut as much as possible according to the shape of the outlet chamber 2 so that the pipe of the second intake hose 3 can be passed through the hot molding process as large as possible.

In addition, the mounting and fixing portion of the second intake hose 3 is formed by forming a notch hole in the cooling cover 13 and fixing the important portion with a jubilee band.

  Next, in an example of a running test result when the intake system piping cooling system of the present invention is attached to the rear arrangement type of the radiator and when it is not installed, the temperature measurement unit is set to a point A (hereinafter referred to as A) The temperature was confirmed thereafter with the exit chamber 2 portion as the B point (hereinafter referred to as B point).

  The temperature of point A and point B was compared after warming up for about 10 minutes in the summer when the temperature was 31 ° C on the day of the engine, but both were almost the same temperature of 30 ° C and there was no difference.

  Next, after running about 15 minutes by repeating the accelerator and brake using the turbo from the normal running for about 15 minutes, the outlet chamber 2 portion at the point B was about 45 ° C. It was about 60 ° C. when the cooling system of the present invention was not installed.

  When the vehicle is stopped in an idling state for about 3 minutes, the cooling cover 13 itself is heated to 70 ° C. or higher, which cannot be touched, but the temperature at the point B gradually rises to about 50 ° C.

  Then, after about 5 minutes of stopping in the idling state, the temperature was raised to a temperature of 65 ° C. or higher so that the outlet chamber 2 at point B could not be touched. It was confirmed that the temperature was increased with a delay after being shielded by the cooling cover 13. Moreover, if a cooling fan was attached to this apparatus and it ventilated to the cooling cover 13 at the time of a stop, this temperature rise would have been suppressed more.

  Next, when the point B exit chamber 2 portion at a point B running at a medium speed of 40-60 Km / h from the state where the point B is heated and running at about 18 Km / h, the temperature is lowered to about 45 ° C. In the absence of the cooling system of the present invention, it was about 70 ° C. in a state where it did not feel a drop in temperature even after running 3 to 4 km and confirmed point B and was not touched.

  Therefore, when the outlet chamber 2 and the second intake hose 3 part after the intercooler main body 1 are heated once, the temperature does not decrease for a long time when it is not installed, but as a result of installing the cooling system of the present invention. It was confirmed that the temperature was lowered quickly even if the temperature of the intake air was suppressed.

  Next, in the winter test, the temperature of the outlet chamber 2 at point B does not always become hot at the same temperature as the front license plate at point A. Although it was warm to about 25 ° C, it quickly cooled down as soon as it started running, and it reached the same temperature as point A.

In an engine with a turbocharger, stable intake air cooling is important. Especially in the summer when the temperature is high, the intake piping cooling system of the present invention exhibits a good combustion effect, and it is comfortable at any time without stress from medium to low speed rotation Blowing up and becoming a high-grade turbo engine with high-temperature countermeasures, improved fuel efficiency.
Another common example is a 2L-class engine with a turbocharger, which has increased the torque by lowering the intake air temperature on the outlet side cooled by the intercooler by 10 ° C, and the output is about 10 horsepower or more. Note that the efficiency of the engine output has been improved by cooling the intake air, as it has been explained.

  In addition to cooling the cooling cover only with the traveling ram pressure air, a fan is attached to the cooling device of the present invention to operate when the traveling ram pressure air is weak or not, or when the temperature rises. In particular, it will be possible to effectively suppress the rise in temperature especially when the vehicle is stopped at high temperatures in summer and when driving at low speeds.

  There is also a method of connecting the air intake port 11 to the hood air intake 22 or the hood 31 (see FIGS. 5 and 6) and connecting it to the cooling cover 13 via the relay duct 12, which is arranged in the engine room. The arrangement of the air intake ports 11 can be selected from a suitable layout.

  Other than the air intake port 11 described above, any location can be used as long as it can take in cooling air, such as the lower part of the headlight or the front part of the bonnet 31.

  The cooling cover 13 extends from the outlet chamber 2 of the intercooler body 1 to the second intake hose 3 in front of the throttle valve 4 or the cooling cover extension portion 13A including the next throttle valve 4 and the surge tank 8 (FIG. 7, FIG. 8).

In the case where the cooling cover extension 13A described above is extended and installed between the outlet chamber 2 and the surge tank 8, the cooling air outlet 20 is a part of the intake manifold 9 so that a longer intake system pipe is provided. Can be cooled until just before being taken into the engine 10.
However, since the pipe length of the intake pipe cooling system becomes longer, the design that takes into account the cooling air flow of the entire system from the air intake port 11 for taking in the traveling ram pressure air 19 to the cooling air outlet 20 is the key to the effect (know-how) become.
