Measurement device for measuring temperature field of vehicle vent pipe

Abstract

The invention discloses a measurement device for measuring the temperature field of a vehicle vent pipe. The device comprises a base, a guide rail fixedly arranged on the base and parallel to the axial direction of the vehicle vent pipe, at least two sensor fixing bases arranged on the guide rail and sensors arranged on the sensor fixing bases. The sensors are in the form of temperature sensors. The sensor fixing bases are slidably mounted onto the guide rail and are fixed at preset places via fixing parts. According to the requirements of desired measurement data, the device is placed at a preset place below the vehicle vent pipe. Meanwhile, the guide rail is ensured to be parallel to the vehicle vent pipe. According to the technical scheme of the invention, a plurality of sensor fixing bases are arranged on the guide rail and sensors are arranged on the sensor fixing bases. Through adjusting the sensor fixing bases, the sensors are driven to reach preset places and then are fixed. In this way, the rapid arrangement of the sensors during measurement is realized. As a result, the number of the sensors is adjustable, and the positions of the sensors are adjustable along the axial and radial directions of the vehicle vent pipe. The measurement result of the measurement device is more comprehensive and more accurate.

Description

technical field [0001] The invention belongs to the field of automobile manufacturing, and in particular relates to a measuring device for the temperature field of an automobile exhaust pipe. Background technique [0002] When the car is running, the fuel burns in the engine to provide power for the car. At the same time, the residual heat of the fuel burned in the engine will be discharged from the exhaust pipe. The exhaust pipe is the main source of heat damage to the vehicle. The surrounding components (wiring harness, Pipelines, etc.) will have aging, burning and other failures in a high-temperature environment for a long time. In order to facilitate the arrangement of peripheral components and prevent heat damage, it is necessary to know the distribution of the temperature field around the exhaust pipe, for example, the temperature conditions of the radial distance of the exhaust pipe at 30mm, 50mm, etc. Thermal resistance is a common method for measuring temperature. ...

AI Technical Summary

Problems solved by technology

Thermal resistance is a common method for measuring temperature. It is necessary to fix the sensor probe at a specific measurement point to collect temperature change signals. In actual measurement, the temperature sensor is generally fixed by tape to fix the measuring probe, but the layout is cumbersome, and the number of sensors cannot be adjusted. , the measurement position is fixed, the measurement data is relatively single, and it is impossible to obtain more comprehensive measurement results
