A vehicle-mounted pulsating heat pipe thermoelectric conversion system applied to the recovery and utilization of waste heat from automobile exhaust, characterized in that the system is mainly composed of three parts: a loop-type duplex pulsating heat pipe, a circuit system and a magnet; wherein, the loop pulsating heat pipe (1) is The main heat transfer and thermal conversion element is a loop formed by connecting multiple copper cooling tubes (5), insulating sleeves (6) and multiple copper heating tubes (7) through threads, and the upper part of the loop is It is equipped with a vacuum valve (2), a low boiling point insulating working fluid filling valve (3) and a high boiling point conductive working fluid filling valve (4). The circuit system includes the power generation electrodes (11) inside each insulating tube, external series insulation Wire (9) and interface electrode (10). The electric energy generated by the present invention can be stored, and can also be directly provided to low-power electrical devices such as taillights and stereos of automobiles, and has high economic efficiency and practicability.
Description
technical field [0001] The invention belongs to the field of automobile exhaust waste heat utilization equipment, in particular to a vehicle-mounted pulsating heat pipe thermoelectric conversion system applied to the recovery and utilization of automobile exhaust waste heat. Background technique [0002] In modern society, automobiles have become the most common means of transportation for people to travel. Since entering the 21st century, the share of automobiles has increased rapidly, and today it has become popular in thousands of households. However, the thermal conversion efficiency of automobile engines is low, and a large amount of heat How to use low-grade waste heat to further improve energy utilization efficiency has become a very important issue today. [0003] The flow pattern of the working medium inside the pulsating heat pipe undergoes the transition from pulsating flow to circulating flow successively with the increase of heating power. The temperature of the...
