Air heater comprehensive performance testing system

Abstract

The invention provides an air heater comprehensive performance testing system. The air heater comprehensive performance testing system comprises a draught fan, a stabilization air channel, a pluralityof experimental wind channels, a first temperature sensor, a second temperature sensor, heaters and a controller. One end of the stabilization wind channel is connected to the draught fan, and a pressure regulation device, a flow volume and flow velocity sensor and a temperature sensor are arranged inside the stabilization air channel. One end of each of the plurality of experimental air channelsis connected to the stabilization air channel and a baffle plate is arranged at a connection part between the plurality of the experimental air channels and the stabilization air channel. A solenoidvalve is arranged on the baffle plate. The solenoid is used for switching on / off the baffle plate. The first temperature sensor is arranged at the air inlets of the experimental air channels and a second temperature sensor is arranged at the air outlets of the experimental air channels. The heaters are arranged inside the experimental air channels. The controller is connected to the draught fan,the pressure regulation device, the flow volume and flow velocity sensor, the temperature sensor, the heater and the solenoid valve. The air heater comprehensive performance testing system greatly improves accuracy and efficiency.

Description

technical field [0001] The invention designs an air heater comprehensive performance testing system. Background technique [0002] At present, with the increase of the number of domestic automobiles, more and more exhaust emissions, and more and more environmental pollution, the automobile industry has higher and higher requirements for engine emissions. The main research target of the industry. As an assembly on the engine, the air heater is used to heat the gas entering the engine intake pipe in a low-temperature environment, so as to facilitate the engine to start. Combustion of fuel can effectively improve exhaust emissions. Therefore, high-efficiency heating is highly sought after, and a test system for various performance indicators of heaters derived from this came into being. Most of the current test systems are single electrical performance tests. This system has certain limitations. It can only perform simple voltage, current, temperature and heater time tests, ...

AI Technical Summary

Problems solved by technology

Most of the current test systems are single electrical performance tests. This system has certain limitations. It can only perform simple voltage, current, temperature and heater time tests, and cannot simulate real vehicle conditions while performing ventilation and power experiments. Moreover, the experimental data records need to be recorded manually, and cannot be stored and processed automatically, so the experimental efficiency is relatively low
