Abstract

The invention relates to an automobile engine tail gas waste-heat and electricity converting stand test device and method for controlling the same. The automobile engine tail gas waste-heat and electricity converting stand test device comprises an automobile engine unit, a waste-heat and electricity converting unit, an outputting and energy storing unit, a temperature detecting unit, a single-module patrolling unit and a main control unit and is characterize in that the automobile engine unit uses an automobile engine to drive a power generator to generate power to be combined to the three-phase commercial power and exhaust the high-temperature tail gas; the waste-heat and electricity converting unit absorbs the waste-heat from the tail gas and converts the waste-heat into the DC electricity; the outputting and energy storing unit changes the voltage of the generated DC electricity so as to supply the DC electricity to the load or store the DC electricity; the temperature detecting unit detects the temperature information of all the units; the single-module patrolling unit patrols the terminal voltages of waste-heat and electricity converting modules which are connected in parallel under each temperature gradient; and the main control unit detects the outputted voltage, the outputted current and other parameters, sends the control information and comprehensively manages the energy. The automobile engine tail gas waste-heat and electricity converting stand test device can simulate the automobile-mounted running environment and is suitable for the test and the research of the automobile engine tail gas waste-heat and electricity conversion.

Description

technical field

[0001] The invention belongs to a thermoelectric conversion device and a control method, in particular to a thermoelectric conversion bench test device and a control method for exhaust heat of an automobile engine exhaust. Background technique

[0002] In recent years, due to the continuous improvement of the performance of thermoelectric materials in technology, as well as factors such as the greenhouse effect and carbon dioxide emission reduction on environmental issues, the use of thermoelectric conversion technology to further convert a large amount of waste heat into electrical energy has been widely accepted by Japan, the United States, Europe, etc. attention of advanced countries. Low-temperature waste heat, especially the reuse of waste heat below 300°C, has increased the competitiveness of thermoelectric power generation. Some emerging application research, such as waste incineration waste heat, steel plant waste heat, especially the use of waste hea...
