Description

Technical Field

[0001] The utility model belongs to the technical field of automotive three-way catalytic converter heat insulation, and particularly relates to a new type of three-way catalytic converter heat insulation mechanism. Background Technique

[0002] The three-way catalytic converter of an automobile is a purification device installed at the tail of the automobile exhaust pipe and used to purify the automobile exhaust gas. Its main purpose is to convert harmful gases such as CO, HC, and NOx contained in the automobile exhaust gas into harmless carbon dioxide, water, and nitrogen through oxidation and reduction, and then discharge them into the atmosphere. It is of great significance for improving the automobile emission standard and the air quality. However, since the temperature of the exhaust gas discharged from the automobile is relatively high, this will cause the temperature of the three-way catalytic converter to be relatively high. And since the three-way catalytic converter is a good heat conductor, it is easy to cause the rubber parts around the three-way catalytic converter to age and fail due to high temperature, reducing the service life of the three-way catalytic converter.

[0003] The existing three-way catalytic converter heat insulation mechanism has a relatively bulky structure, making it difficult to fix, and prone to vibration and even loose damage. Content of the Utility Model

[0004] The purpose of the utility model is to provide a new type of three-way catalytic converter heat insulation mechanism to solve the problems that the existing three-way catalytic converter heat insulation mechanism has a relatively bulky structure, making it difficult to fix, and prone to vibration and even loose damage.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a new type of three-way catalytic converter heat insulation mechanism, including a three-way catalytic converter body, an auxiliary heat dissipation ring plate, and a clamping component. The auxiliary heat dissipation ring plate is a ring-shaped structure with a notch. A heat conduction sleeve is sleeved on the circumferential side of the three-way catalytic converter body. The three-way catalytic converter body is arranged inside the auxiliary heat dissipation ring plate. A plurality of heat dissipation fins are fixedly connected to the inner side surface of the auxiliary heat dissipation ring plate. The heat dissipation fins are in contact with the heat conduction sleeve. An insulation cavity is formed inside the auxiliary heat dissipation ring plate.

[0007] An air inlet pipe is fixedly connected to the upper side of one end of the auxiliary heat dissipation ring plate, and an air outlet pipe is fixedly connected to the lower side of the other end. One ends of the air inlet pipe and the air outlet pipe are respectively arranged inside the insulation cavity. The air inlet pipe is connected to an external automobile air conditioning pipeline, and a one-way valve is arranged inside the air outlet pipe.

[0008] The clamping assembly includes a connecting block, a clamping rod and a mating block. The connecting block and the mating block are respectively arranged on both sides of the notch of the auxiliary heat dissipation ring plate and fixedly connected thereto. The clamping rod is arranged in the connecting block and is slidably matched with it. A mating spring is fixedly connected to one side surface of the connecting block. One end of the clamping rod is arranged in the mating spring and is rotatably connected thereto. The other end of the clamping rod is fixedly connected with a limiting rod, and the limiting rod is arranged outside the connecting block.

[0009] A mating groove is formed inside the mating block. The mating groove is adapted to the clamping rod and the limiting rod. A limiting groove is formed on one side surface of the mating block. The limiting groove is adapted to the limiting rod. By arranging the above structure, the auxiliary heat dissipation ring plate is sleeved on the three-way catalytic converter body, and then the clamping rod is squeezed to move it in the connecting block and squeeze the mating spring. Further, the clamping rod and the limiting rod are passed through the mating groove of the mating block, and then the clamping rod is rotated to align the limiting rod with the limiting groove. The clamping rod is released, and under the action of the mating spring, the limiting rod is clamped with the limiting groove, thereby fixing the auxiliary heat dissipation ring plate on the three-way catalytic converter body 1.

[0010] The utility model has the following beneficial effects:

[0011] By arranging the heat conduction sleeve and the auxiliary heat dissipation ring plate, the utility model utilizes the heat conduction sleeve to accelerate the heat conduction speed of the three-way catalytic converter body and dissipate heat through the heat dissipation fins. The cold air inlet pipe is connected to the existing automobile air-conditioning pipeline to cool the heat insulation cavity and further dissipate heat from the heat dissipation fins, improving the heat dissipation efficiency of the three-way catalytic converter body. By arranging the clamping assembly, the clamping rod is squeezed to move it in the connecting block and squeeze the mating spring. Further, the clamping rod and the limiting rod are passed through the mating groove, and then the clamping rod is rotated to align the limiting rod with the limiting groove. The clamping rod is released, and under the action of the mating spring, the limiting rod is clamped with the limiting groove, thereby fixing the auxiliary heat dissipation ring plate on the three-way catalytic converter. The structure is simple, convenient for fixing and disassembling.
