Description

Technical Field

[0001] The utility model relates to the technical field of automotive parts, and particularly relates to an intake manifold with a filtering function. Background Art

[0002] The intake manifold is composed of a pipeline outside the engine. The intake manifold refers to the intake pipeline from behind the carburetor or throttle body to the intake port of the cylinder head. Its function is to distribute the air-fuel mixture from the carburetor or throttle body to the intake ports of each cylinder.

[0003] For example, in the Chinese utility model intake manifold, engine and vehicle with the publication number CN217233676U, the preliminary mixing of various gases is realized by setting a mixing pipe part connected to the manifold main pipe, so that the fresh air in the manifold main pipe is more evenly mixed with various recycled gases, and stable combustion can be ensured after entering each cylinder, avoiding the occurrence of phenomena such as excessive emissions, performance degradation and unqualified NVH. However, such a structure still has the following several significant defects:

[0004] 1. The intake manifold needs to filter the incoming gas to prevent impurities in the air from entering the intake manifold body. During maintenance, the entire automotive internal combustion engine intake manifold needs to be disassembled, resulting in high maintenance costs;

[0005] 2. The hot air pressurized by the supercharger enters the intake manifold. Due to its high temperature, it is difficult to quickly cool in the pressure stabilizing cavity, thus affecting the intake efficiency of each branch pipe and ultimately reducing the overall working performance of the engine.

[0052] Next, a kind of intake manifold with a filtering function provided by the embodiments of the present application will be described in detail with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0053] Embodiment 1:

[0054] As Figures 1 to 3 shown, the embodiment of the present application provides an intake manifold with a filtering function, including: a body 1, an intake main pipe 2, an intake port 3, branch pipes 4, and a pressure stabilizing chamber 5; further including: a filtering structure 6 for preventing impurities in the air from entering the body 1; a heat dissipation structure 7 for quickly cooling the gas in the pressure stabilizing chamber 5.

[0055] Further, the filtering structure 6 includes: a filter net 61 disposed in the intake main pipe 2; a filter core 62 disposed in the intake main pipe 2; and a fixing structure 63 for fixing the filter net 61 and the filter core 62.

[0056] Further, the filter core 62 is made of synthetic fiber filter cotton material.

[0057] Further, the fixing structure 63 includes: an internal thread 631 disposed on the outer side wall of the filter net 61; an external thread 632 disposed on the inner cavity of the intake main pipe 2; and a rotating shaft 633 disposed on the filter net 61.

[0058] Further, the fixing structure 63 further includes: a threaded hole 634 disposed on the intake main pipe 2; a rotating handle 635 for fixing the filter core 62; and a limiting hole 636 disposed on the filter core 62.

[0059] Further, the rotating handle 635 includes: a threaded rod 637, which is connected to the threaded hole 634 by a thread; a rotating head 638, which is arranged at one end of the threaded rod 637 away from the filter element 62; and an anti-slip pattern 639, which is arranged on the rotating head 638.

[0060] In this embodiment of the present application, due to the adoption of the above structure, during the air intake process, the gas will sequentially enter the pressure stabilizing chamber 5 through the filter net 61 and the filter element 62. The filter net 61 is arranged in the air intake main pipe 2 and can preliminarily filter dust and other impurities in the gas. The filter element 62 is arranged in the air intake main pipe 2, and there is no contact between the front end of the filter element 62 and the rear end of the filter net 61. The filter element 62 is made of synthetic fiber filter cotton material, which can further improve the gas quality, thereby effectively avoiding blockage and damage to the inside of the automobile cylinder block caused by impurities. The filter net 61 and the air intake main pipe 2 are tightly connected together through an internal thread 631 and an external thread 632. Four through threaded holes 634 are also arranged on the air intake main pipe 2, and the four threaded holes 634 are arranged in an equally spaced circumferential array. And a limiting hole 636 corresponding to the threaded hole 634 one by one is also arranged on the filter element 62. The threaded rod 637 on the rotating handle 635 is connected to the threaded hole 634 by a thread, and the bottom of the threaded rod 637 abuts against the limiting hole 636, which can be used to fix the filter element 62. When it is necessary to disassemble and replace the filter net 61 and the filter element 62, the staff can easily separate the filter net 61 from the air intake main pipe 2 by rotating the rotating shaft 633 at the center of the filter net 61 counterclockwise, remove the filter net 61 for cleaning, and then rotate the four rotating heads 638 clockwise respectively. The anti-slip pattern 639 is arranged on the rotating head 638, and the anti-slip pattern 639 can ensure that it is not easy to slip during the rotation process. By rotating, the threaded rod 637 is separated from the limiting hole 636, which is convenient to take out and replace the filter element 62. The whole process is efficient and convenient, effectively reducing the maintenance cost.

[0061] Embodiment 2:

[0062] As Figures 1 to 4 shown, in this embodiment, in addition to including the structural features of the foregoing embodiment, the heat dissipation structure 7 includes: a heat dissipation chamber 71, which is arranged in the pressure stabilizing chamber 5; a water inlet pipe 72, which is arranged on the heat dissipation chamber 71; and a water outlet pipe 73, which is arranged on the heat dissipation chamber 71.

[0063] Further, the heat dissipation chamber 71 includes: a connection groove 711, which is arranged on the inner wall of the heat dissipation chamber 71; a heat exchange pipe 712, which is connected to the connection groove 711; and heat exchange fins 713, which are arranged on the heat exchange pipe 712.

[0064] Further, the connection groove 711 includes: a water outlet groove 714, one end of which is connected to the water outlet pipe 73; and a water inlet groove 715, one end of which is connected to the water inlet pipe 72.

[0065] Further, the heat dissipation structure 7 further includes: an air inlet passage 74, which is arranged at one end of the heat dissipation chamber 71 away from the branch pipe 4; and an air outlet passage 75, which is arranged at one end of the heat dissipation chamber 71 close to the branch pipe 4.

[0066] In this embodiment of the present application, due to the above structure, after the gas flows from the intake main pipe 2 into the pressure stabilizing chamber 5, the gas is evenly distributed to the 4 branch pipes 4 through the flow splitting grooves in the pressure stabilizing chamber 5. Before entering the branch pipe 4, the gas will first enter the heat dissipation chamber 71 through the air inlet passage 74. A water outlet pipe 73 is arranged above the heat dissipation chamber 71, and a water inlet pipe 72 is arranged below the heat dissipation chamber 71. The water outlet pipe 73 and the water inlet pipe 72 penetrate through the intake main pipe 2. One ends of the water outlet pipe 73 and the water inlet pipe 72 are respectively connected to the water outlet groove 714 and the water inlet groove 715, and the other ends are connected to the cooling circulating water, so that the cooling circulating water can enter from the bottom and exit from the top, which can effectively prevent air bubbles from appearing in the connection groove 711, thereby ensuring the heat exchange efficiency. Four layers of heat exchange pipes 712 are arranged between the water outlet groove 714 and the water inlet groove 715. Four heat exchange pipes 712 are equidistantly arranged in the direction perpendicular to the water outlet pipe 73 for each layer of heat exchange pipes 712. 20 heat exchange fins 713 are equidistantly arranged along the length direction of the heat exchange pipes 712. The heat exchange fins 713 can effectively increase the contact area between the gas and the heat exchange pipes 712, improve the heat exchange efficiency, and enable the gas to quickly reduce the temperature before leaving the heat dissipation chamber 71 through the air outlet pipe 75, thereby reducing the influence on the intake efficiency of each branch pipe 4.
