Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a cooling device for a muffler. Background Technology

[0002] An automotive muffler is a component used to reduce the noise generated by the engine of a motor vehicle. It eliminates noise by reducing and attenuating the pulse of exhaust pressure. The temperature of the exhaust gas inside the car is quite high in the initial stage of exhaust, and the exhaust gas is most active at this time, generating the most noise. High-temperature exhaust gas entering the muffler can easily damage the muffler material. In order to improve the service life of the muffler, this utility model provides a cooling device for the muffler. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a cooling device for a muffler that can absorb heat from high-temperature exhaust gases and reduce the damage caused by high-temperature exhaust gases to the muffler.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for a muffler, comprising a first air pipe, a dispersion pipe, a concentration pipe, a second air pipe, and a branch pipe;

[0005] The first trachea has its outlet end fixedly connected to one end of the dispersion tube. Multiple bronchial tubes are provided and fixedly installed between the dispersion tube and the concentration tube. The second trachea has its inlet end fixedly connected to one end of the concentration tube.

[0006] Also includes:

[0007] The cooling pipe is provided in multiple parts, with one cooling pipe on the outside of each branch pipe. The two ends of each branch pipe along its length are fixedly connected to the dispersing pipe and the concentrating pipe, respectively. A cooling chamber is formed between the inner surface of each cooling pipe and the branch pipe. The interiors of the multiple branches pipes are connected by a connecting pipe.

[0008] The guide plate is set to an inclined state, and its top end is fixedly connected to the central pipe.

[0009] Preferably, a plurality of heat sinks are fixedly mounted on the outer surface of each cooling pipe.

[0010] Preferably, the dispersing tube and the concentrating tube are fixedly connected to a stabilizing plate by multiple connecting rods.

[0011] Beneficial effects

[0012] Compared with the prior art, this utility model provides a cooling device for a muffler, which has the following features:

[0013] Beneficial effects:

[0014] By setting up a first air pipe, a dispersion pipe, a concentration pipe, a second air pipe, and multiple branch pipes, and setting a cooling pipe on the outside of each branch pipe, a cooling chamber is formed between the inner surface of each cooling pipe and the branch pipe. The interiors of multiple branch pipes are connected by a connecting pipe. The coolant absorbs the heat in the high-temperature exhaust gas in the branch pipe, reducing the damage of the high-temperature exhaust gas to the muffler.

[0015] An inclined baffle is fixedly installed on the central pipe. The bottom end of the central pipe is closest to the front of the vehicle. During vehicle operation, the baffle guides the airflow so that the airflow passes over the baffle. The high-speed airflow can accelerate the dissipation of heat in the coolant and ensure that the coolant can stably and effectively absorb the heat in the exhaust gas.

[0023] The following is in conjunction with the appendix Figures 1 to 4The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0024] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Please combine Figures 1 to 4 As shown, this utility model provides a cooling device for a muffler. The cooling device is installed between the catalytic converter and the muffler. The cooling device includes a first air pipe 1, a dispersion pipe 2, a concentration pipe 4, a second air pipe 5, and a branch pipe 9.

[0027] The first air pipe 1 is fixedly connected to one end of the dispersion pipe 2. Multiple branch pipes 9 are provided and fixedly installed between the dispersion pipe 2 and the concentrator pipe 4. The inlet end of the second air pipe 5 is fixedly connected to one end of the concentrator pipe 4. The exhaust gas treated by the catalytic converter enters the dispersion pipe 2 through the first air pipe 1 and is dispersed by the dispersion pipe 2 into multiple branch pipes 9. The exhaust gas in the multiple branch pipes 9 will be collected into the concentrator pipe 4 and finally transported to the silencer by the second air pipe 5.

[0028] Also includes:

[0029] Multiple cooling pipes 10 are provided, one of which is provided on the outside of each branch pipe 9. The two ends of each branch pipe 9 in the length direction are fixedly connected to the dispersion pipe 2 and the concentration pipe 4 respectively. A cooling chamber is formed between the inner surface of each cooling pipe 10 and the branch pipe 9. The interiors of the multiple branch pipes 9 are connected by a connecting pipe 11. Coolant is stored in the cooling chamber and surrounds the outside of the branch pipe 9. When the high-temperature exhaust gas flows in the branch pipe 9, the heat in the exhaust gas is absorbed by the coolant, thereby reducing the temperature of the exhaust gas. As a result, the exhaust gas delivered to the muffler by the second air pipe 5 has a lower temperature, which reduces the damage to the muffler and helps to extend the service life of the muffler.

[0030] The deflector 6 is set to an inclined state, and its top end is fixedly connected to the central pipe 4 through the connecting block 7. The bottom end of the central pipe 4 is closest to the front of the vehicle. When the vehicle is driving, the airflow speed around the vehicle is relatively fast. The airflow contacts the upper surface of the deflector 6. The deflector 6 guides the airflow so that the airflow passes over the deflector 6. The high-speed airflow can accelerate the dissipation of heat in the coolant and ensure that the coolant can stably and effectively absorb the heat in the exhaust gas.

[0031] In addition, multiple heat sinks 12 are fixedly installed on the outer surface of each cooling pipe 10; the heat dissipation capacity of the cooling pipe 10 is increased by using multiple heat sinks 12.

[0032] The distribution pipe 2 and the central pipe 4 are fixedly connected to a stabilizing plate 3 by multiple connecting rods 8. The stabilizing plate 3 is fixedly connected to the chassis of the car. The stabilizing plate 3 can be fixed to the chassis of the car by bolts or welding. The stabilizing plate 3 is used to increase the stability of the cooling equipment after installation.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
