Embodiment Construction

[0013] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0014] Such as Figure 1~3 As shown, the present invention mainly includes an air inlet pipe 1, a recovery pipe body 2 and an air outlet pipe 3, and a diversion chamber 6 and a heat energy recovery chamber 7 are arranged side by side in the recovery pipe body 2, and an air inlet mixing chamber 7 is arranged at both ends of the recovery pipe body 2. Chamber 4 and outlet mixing chamber 5.

[0015] The intake end of the intake mixing chamber 4 is connected to the intake pipe 1 , and the outlet end of the intake mixing chamber 4 communicates with the guide chamber 6 and the heat energy recovery chamber 7 . The intake mixing chamber 4 is used for the mixing and splitting of the incoming airflow. The internal shape of the mixing chamber should be analyzed and tested to ensure that other structures can smoothly enter the following structures.

Abstract

The invention relates to an automobile aftertreatment device, in particular to a heat energy recovery device for an automobile aftertreatment system and belongs to the technical field of automobile aftertreatment equipment. The heat energy recovery device for the automobile aftertreatment system comprises a gas inlet pipe, a recovery pipe body and a gas outlet pipe; a flow guiding cavity and a heat energy recovery cavity are disposed in the recovery pipe body vertically side by side; a gas inlet mixing cavity and a gas outlet mixing cavity are disposed in the two ends of the recovery pipe bodycorrespondingly; the gas inlet end of the gas inlet mixing cavity is connected with the gas inlet pipe; the gas outlet end of the gas inlet mixing cavity communicates with the flow guiding cavity andthe heat energy recovery cavity; the gas outlet end of the gas outlet mixing cavity is connected with the gas outlet pipe; the gas inlet end of the gas outlet mixing cavity communicates with the flowguiding cavity and the heat energy recovery cavity; and a plurality of flow guiding pipes which are uniformly distributed are disposed in the heat energy recovery cavity, and the front ends and the rear ends of the multiple flow guiding pipes extend out of pipe plates to communicate with the gas inlet mixing cavity and the gas outlet mixing cavity correspondingly. By means of the heat energy recovery device for the automobile aftertreatment system, high-efficiency recovery of the heat energy of automobile exhaust can be achieved, the energy utilization ratio of an engine is effectively improved, emission of the engine is reduced, and a heat dissipation structure can be reasonably arranged according to the heat energy recovery index.

Description

technical field [0001] The invention relates to a vehicle post-processing device, in particular to a heat recovery device used in a vehicle post-processing system, and belongs to the technical field of vehicle post-processing equipment. Background technique [0002] With the tightening of national environmental protection regulations, there are more stringent requirements for automobile fuel consumption. Usually, a large part of the energy has been discharged into the atmosphere in the form of exhaust gas. It is very good to add heat recovery devices to the post-processing system. prospect. [0003] In China, due to recovery performance, product reliability, processing technology and other reasons, research on vehicle heat recovery devices is relatively lagging behind. Therefore, the development of a reasonable and effective vehicle heat recovery device has good research value and application prospects. Contents of the invention [0004] The purpose of the present invent...
