Description

Technical Field

[0001] The present invention relates to the technical field of vehicle cooling systems, and in particular to a vehicle cooling module. Background Art

[0002] The vehicle cooling module is arranged in the engine compartment of the vehicle. A fan is usually installed on one side of the vehicle cooling module. The fan rotates to provide air flow exchange for the vehicle cooling module, and finally heat exchange is performed through the air flow to achieve the effect of cooling the interior of the vehicle.

[0003] The vehicle cooling module under the prior art is installed inside the vehicle through connecting components, and the radiator and the intercooler are respectively fixed on the frame. However, during the driving of the vehicle, the vibration of the frame will be transmitted to the vehicle cooling module. Since the vehicle cooling module will be displaced after absorbing the vibration, this will cause the vehicle cooling module to be out of the installation position. At the same time, errors may occur in the space inside the frame during the assembly process, resulting in the vehicle cooling module itself generating stress due to the error after the assembly is completed. Since the stress acts on the connection position between the vehicle cooling module and the frame, the thrust may cause the tightness of the connection between the vehicle cooling module and the frame to decrease over time. The vehicle cooling module is connected to the frame through a pull rod, and an annular sleeve is formed at the end of the pull rod. The fixing bolt passes through the annular sleeve and is fastened to the vehicle cooling module. Rubber is filled between the fixing bolt and the pull rod ring, but as the air becomes cold, the rubber The rubber parts shrink, and the annular sleeve may directly rub against the vehicle cooling module, which will increase abnormal noise during vehicle driving. At the same time, the intercooler pipe will easily crack during vibration due to the small welding area. The intercooler is ventilated with compressed air. In summer, the air is humid and condensed water will be produced after compression. Water will condense rapidly in the intercooler. Condensed water entering the engine will cause fire, and over time it will cause oil dilution and even engine cylinder pulling problems. The engines of existing commercial vehicles have always had this problem. Closed crankcase ventilation will introduce part of the engine's gas into the intake system, so there will always be water in the intercooler. The existing technology is to set a drain hole that is always connected to the atmosphere at the bottom of the intercooler, but this will cause the intercooler to be connected to the atmosphere when exhaust is not needed, which will reduce the engine's power and economy, and at the same time increase the energy consumed by the vehicle, and increase the cost of use.

DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0022] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0024] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0025] In the prior art, due to the unreasonable connection between the intercooler and the radiator, the radiator and the intercooler will become loose from the frame. During the driving of the vehicle, the radiator and the intercooler will become loose from the frame, causing friction between the two, and eventually causing noise, which reduces the driving stability of the vehicle.

[0026] In order to solve the above problems, Figures 1 to 4As shown, the present invention provides a vehicle cooling module, including an intercooler 1 and a radiator 2, wherein the upper and lower ends of the intercooler 1 are connected to the radiator 2 through a first auxiliary rod 3, and the two sides of the bottom of the radiator 2 are connected to the frame through a second auxiliary rod 4, and shock absorbing modules 5 are installed on both sides of the middle of the radiator 2, and the shock absorbing module 5 is connected to the frame; shock absorbing blocks 51 are installed in the shock absorbing module 5, a group of shock absorbing blocks 51 are formed with a circular hole 511 at the bottom, and another group of shock absorbing blocks 51 are formed with an elliptical hole 512 at the bottom, and the fixing bolts on the frame pass through the circular hole 511 and the elliptical hole 512 respectively to be connected to the shock absorbing blocks 51.

[0027] The intercooler 1 and the radiator 2 are fixed by the first auxiliary rod 3, and the intercooler 1 is decoupled from the frame. The vibration of the vehicle will not be directly transmitted to the intercooler 1, but will be directly transmitted to the radiator 2 through the shock absorbing module 5. Part of the vibration will be directly absorbed by the shock absorbing module 5 and the second auxiliary rod 4, thereby reducing the amplitude of the vibration of the parts in the vehicle cooling module. In addition, the shock absorbing module 5 of the present invention includes two groups, one of which has a circular hole 511 on the lower side, which is convenient for fixing the radiator 2 to the frame, and the other group of shock absorbing modules The lower side of 5 is an elliptical hole 512, so that the connection position of the shock absorbing module 5 can be changed on the frame, so that the vehicle cooling module can be fixed at a suitable position, the stress on the vehicle cooling module can be reduced, and the vehicle cooling module can be fastened to the frame for a long time without shaking. At the same time, by changing the installation position of the vehicle cooling module, the vehicle cooling module can adapt to the errors on the frame and reduce the difficulty of installation. The first auxiliary rod 3 and the second auxiliary rod 4 are made of aluminum alloy and can withstand the vibration transmitted to the frame during the driving of the vehicle.

[0028] A first fixing hole is formed on the top of the shock absorbing block 51 , and a fixing bolt on the frame passes through the first fixing hole and is connected to the shock absorbing block 51 . The diameter of the first fixing hole is larger than the circular hole 511 .

[0029] After the first fixing hole is connected to the vehicle frame, the installation position of the vehicle cooling module can be quickly located. The circular hole 511 and the elliptical hole 512 on the lower side have larger diameters, which are convenient for the fixing bolts to penetrate and for installation, thereby reducing the difficulty of installation. The shock absorbing block 51 of the present invention is made of rubber material. A metal sleeve is installed at the center of the shock absorbing block 51. The fixing bolt can be screwed into the metal sleeve. The rubber shock absorbing block 51 is clamped in the middle to absorb vibration and improve stability. The shock absorbing block 51 is installed in the shock absorbing bracket 52, and the shock absorbing bracket 52 is fixed on the side of the heat dissipation.

[0030] The shock absorbing block 51 has protrusions on the upper and lower sides to form a shock absorbing limit part, which abuts against the frame. When the shock absorbing block 51 contracts in a cold environment, the shock absorbing limit part can still abut against the frame, so that a certain gap is formed between the shock absorbing module 5 and the frame to avoid direct contact, thereby reducing the noise generated by the vehicle cooling module during driving.

[0031] A convex groove 6 is welded on the intercooler 1, and a first nut 7 is installed in the convex groove 6. One end of the first auxiliary rod 3 is connected to the radiator 2 through three groups of connecting bolts. A first annular groove 31 is formed at the other end of the first auxiliary rod 3. The first annular groove 31 is filled with a first rubber 9. The first bolt 8 passes through the first rubber 9 and is screwed into the first nut 7. A first limiting portion 91 is formed on one side of the first rubber 9 close to the first nut 7, and the first limiting portion 91 abuts against the intercooler 1.

[0032] By providing the first limiting portion 91, when the vehicle cooling module is in a cold environment, even if the first rubber 9 contracts, the first limiting portion 91 can still abut against the intercooler 1, thereby preventing the intercooler 1 from directly contacting the first auxiliary rod 3 and reducing noise. The intercooler 1 can be directly fixed on the radiator 2 through the first auxiliary rod 3. Before installing the vehicle frame, the intercooler 1 is first fixed to reduce the difficulty of later installation. At the same time, since the first rubber 9 can absorb vibrations, the vibrations transmitted from the vehicle frame can be absorbed, thereby reducing the amplitude of the vibration of the intercooler 1, decoupling the movements of the intercooler 1 and the frame, and preventing the intercooler 1 from vibrating with excessive amplitude.

[0033] A second annular groove 41 is formed at both ends of the second auxiliary rod 4, and the second annular groove 41 is filled with a second rubber 10. The second bolt passes through the metal sleeve in the second rubber 10 and is screwed into the radiator 2. The second bolt also passes through the metal sleeve in the second rubber 10 and is screwed into the ear plate. The ear plate is connected to the frame. The second rubber 10 is protruded to form a second limiting portion 101 on one side close to the radiator 2, and the second limiting portion 101 abuts against the radiator 2. The second auxiliary rod 4 can provide more connection positions for the radiator 2 to the frame, making the radiator 2 more stable. At the same time, the second rubber 10 can absorb the vibration transmitted from the frame. In addition, the second limiting portion 101 is also provided on the second rubber 10. In a cold environment, the second limiting portion 101 can still abut against the radiator 2 and the ear plate to reduce the probability of noise.

[0034] The intercooler 1 includes a main body 11 and a row pipe 12. U-shaped flanges 111 are formed on both sides of the main body 11. The row pipe 12 is inserted into the U-shaped flanges 111, and the row pipe 12 is welded to the main body 11. By providing the U-shaped flanges 111, the contact area between the row pipe 12 and the main body 11 can be increased. During the welding process, the main body 11 and the row pipe 12 can be welded more firmly to avoid cracking during vibration.

[0035] The radiator 2 includes a heat sink 21 and a frame 22. The heat sink 21 is installed inside the frame 22. The frame 22 is provided with a weight-reducing hole 221. By providing the weight-reducing hole 221 on the frame 22, the overall mass of the vehicle cooling module can be made lighter, thereby making the inertia of the vehicle cooling module smaller during vibration, thereby reducing the impact on the first rubber 9, the second rubber 10 and the shock-absorbing block 51.

[0036] A drainage hole is provided at the bottom of the intercooler 1, and a drainage valve 20 is inserted into the drainage hole. The drainage valve 20 includes a shell 201. A movable part 202 is abutted against the shell 201 through a spring 203. A first drainage hole is provided on the movable part 202, and the drainage hole connects the interior of the intercooler 1 with the interior of the shell 201. A second drainage hole 204 is provided at the bottom of the shell 201, and the second drainage hole 204 is connected to the outside.

[0037] During the operation of the intercooler 1, pressure is generated inside the intercooler 1, and the movable part 202 can be pressed against the bottom of the surgery, abutting against the second drain hole 204, so that the inside of the intercooler 1 forms a closed state, improving the power and economy of the engine and reducing the energy consumed by the engine. After the intercooler 1 is closed, the spring 203 pushes the movable part 202 upward, so that the inside of the intercooler 1 is connected to the outside through the first drain hole and the second drain hole 204, so that the condensed water inside the intercooler 1 can be discharged, avoiding the problem of cylinder pulling during the engine startup process. During the operation of the engine, the spring 203 is compressed, and the drain valve 20 returns to the closed state.

[0038] The exhaust pipe 12 is installed around both sides of the main body 11, which can save installation space. During the vibration of the vehicle, the impact of the exhaust pipe 12 on the heat dissipation gas is reduced, which can protect the radiator 2 and extend the service life of the radiator 2.

[0039] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
