摘要:

为了研究重力热管在车辆中冷器上的应用可行性,设计用于冷却高温增压空气的热管中冷器.选用水作为工作介质,在风洞实验台架上进行热管中冷器的传热和阻力性能实验.测试热管中冷器在不同冷侧空气流速、冷﹑热侧空气进口温差、热侧空气流量下的散热量和压力降,比较并分析测试结果.结果表明,热管中冷器具有良好的散热性能,在一定范围内可以满足高增压内燃机的散热要求.将实验结果与理论模型计算值进行比较,结果表明,实验值与理论计算值变化趋势吻合较好.

Abstract:

A heat pipe heat exchanger was constructed for cooling hot compressed airflow in order to analyze the feasibility in the vehicle heat exchanger by using water as the working fluid. Experimental studies on the heat transfer and pressure drop characteristics were performed on the wind tunnel test rig. The characteristics of heat transfer and pressure drop for different inlet air velocities, temperature differences and hot compressed air mass flow were analyzed and compared with theoretical results. Results show that the heat pipe heat exchanger has effective heat rejection performance and can satisfy the heat rejection requirement of highly turbocharged engine in a certain range. The experimental results agreed well with the theoretical results.
