    Intercooler Chiller of Test Engine
    The present invention relates to a cooling device for cooling an inter cooler such that the intake air passing through the inter cooler in a test equipment of a diesel engine is below a certain temperature, and in particular, the coolant is ejected by showering from the upper side of the water tank in which the inter cooler is embedded. The present invention relates to an intercooler cooling device for a test engine, in which air bubbles are formed in the cooling water so that the cooling effect of the intercooler is sufficiently maintained.
    In general, an intake system of a diesel engine is provided with an inter cooler to cool intake air as shown in FIG. 1. That is, the exhaust gas discharged from the engine 2 rotates the turbine 1a of the turbocharger 1, and the compressor 1b is operated by the rotation of the turbine 1a. The compressor 1b supercharges the air sucked through the air cleaner 3 and sends it to the intake manifold 4 and the combustion chamber. At this time, the temperature of the air passing through the compressor (1b) is raised by a certain amount of heat and compression of the exhaust gas so that the intercooler 10 is installed in the middle to make cold air to be sent to the combustion chamber.
    In order to test the diesel engine including the inter cooler 10, the inter cooler 10 should perform a cooling function under the same conditions as when the vehicle is driving. That is, when driving the engine 2 in a state arranged in accordance with the necessity of various tests indoors, the intercooler 10 does not have a sufficient cooling function because the vehicle does not travel.
    Therefore, in order to perform the cooling function under the same condition as the state in which the inter cooler 10 is running, an apparatus capable of cooling the inter cooler 10 is required.
    Here, the intercooler cooling apparatus of the conventional test engine includes a rectangular tank 20 having an upper surface open so that the inter cooler 10 may be embedded as shown in FIG. 2, and the intercooler in the tank 20. The cooling water inlet 22 and the cooling water outlet 24 are formed on both sides to allow the cooling water to flow in and out.
    Here, the cooling water inlet 22 is formed on the side of the middle height of the water tank 20, the cooling water outlet 24 is formed on the side of the water tank 20 that is higher than the cooling water inlet (22).
    The intercooler cooling apparatus of the conventional test engine configured as described above cools the intercooler 10 in the water tank 20 while introducing and cooling the coolant to secure conditions similar to the driving conditions. That is, when the test engine 2 is operated, intake air passing through the compressor 1b of the turbocharger 1 flows into the inter cooler 10, and the intake air passing through the inter cooler 10 inside the tank 20 Heat is exchanged with the coolant in the c) to cool. The intake air thus cooled is sucked into the combustion chamber through the intake manifold 4.
    However, in the conventional intercooler cooling device of the test engine constructed and operated as described above, since the upper part of the inter cooler 10 placed inside the water tank 20 is exposed to air by buoyancy of the cooling water, heat exchange with the cooling water. This is not made sufficiently, and thus there is a problem that the cooling efficiency of the inter cooler 10 is lowered.
    In addition, in the related art, since the coolant in the water tank 20 that cools the inter cooler 10 is simply introduced and discharged, sufficient flow force is not generated between the inside of the water tank 20 and the inter cooler 10 so that the inter cooler ( 10) There is a problem that a limit occurs in cooling.
    The present invention has been made to solve the above problems, the cooling effect of the inter cooler by cooling the inter cooler by ejecting the coolant in the shower type in the inter cooler on the upper side of the tank and forming air bubbles in the coolant stored in the tank. It is to provide an intercooler cooler for the test engine that is raised to allow more efficient engine testing.

    In the intercooler cooling device of the test engine of the present invention for realizing the above object, a water tank of a rectangular body in which the inter cooler is embedded and the coolant flows in and out so that the inter cooler installed in the test engine has a cooling function of intake air is provided. An inter cooler cooling apparatus for a test engine including: a coolant jetting pipe positioned in an upper direction in an upper side of the water tank for discharging the coolant in a shower; And a cooling water outlet through which cooling water is discharged so as to be immersed, and an air providing tube positioned in a long direction in the lower side of the water tank to generate air bubbles in the stored cooling water.
    Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
    As shown in FIG. 3, an inter cooler cooling apparatus of a test engine according to the present invention includes a water tank 60 of a rectangular body in which an inter cooler 50 is embedded and coolant flows in and out, and an upper side of the water tank 60. A cooling water jet pipe 70 positioned in a long direction to eject the cooling water in a shower type, and a cooling water outlet formed at a central position of the side surface of the water tank 60 to discharge the cooling water so that the inter cooler 50 is half closed; 65) and an air providing tube 80 positioned in the longitudinal direction in the water tank 60 to generate air bubbles in the stored coolant.
    Here, the coolant jet pipe 70 is positioned so that the coolant may be jetted to an upper portion of the inter cooler 50 inclined in the water tank 60, and a plurality of nozzle holes 70a through which the coolant is jetted are formed. It is.
    The air providing tube 80 has an air nipple 82 protruding from the water tank 60 to the outside of the water tank 60 so that air is introduced from the outside of the water tank 60, and a predetermined interval is provided so that air is discharged around the tube. Thus, a plurality of air outlets 82a are formed.
    Referring to the operation of the intercooler cooling device of the test engine according to the present invention configured as described above are as follows.
    When the intercooler of the test engine is placed in the water tank 60 according to the present invention, the coolant flowing into the water tank 60 from the coolant jet pipe 70 on the upper side of the water tank 60 is ejected to the upper side of the inter cooler 50. Then, the air comes out from the air supply tube 80 located below the water tank 60 to form air bubbles. Then, when the coolant in the water tank 60 is above a predetermined height, the coolant flows out of the water tank 60 through the coolant outlet 65.
    That is, the coolant is ejected to the upper side of the inter cooler 50 through the nozzle hole 70a of the cooling water jet pipe 70, and is stored under the water tank 60 while cooling the inter cooler 50. In addition, in the lower side of the water tank 60, the air introduced through the air nipple 82 is introduced into the cooling water through the air outlet 82a of the air supply tube 80 to form air bubbles, and the air bubbles are intercooler 50 ) And the bubble bursts to cool the inter cooler 50.
    The cooling water having a cooling action in the water tank 60 goes out through the cooling water outlet 65 formed at the middle side of the water tank 60.
    The intercooler cooling device of the test engine according to the present invention constructed and acting as described above is cooled by the coolant ejected from the coolant jet pipe in a state where the upper end of the intercooler placed in the water tank is exposed to the atmosphere, and the lower end provides air. Because of the cooling by the air bubbles generated in the tube, the cooling effect of the inter cooler is improved, which is an advantage of effectively performing the engine test.
