摘　　要：通过搭建风洞台架试验系统及虚拟风洞数值计算模型,对某装载机动力舱散热流场展开研究,并通过调整风扇在挡风罩内的沉入量对散热量进行优化。研究结果表明:散热风量随风扇转速提升呈线性增长;随着风扇沉入量从-30 mm增加至120 mm,通过散热器的总风量不断降低,在进行散热系统设计时应综合考虑散热器的换热面积与安装位置;相较于台架试验,采用虚拟风洞数值计算方法能够更加全面和高效地对动力舱内部展开分析与优化。By building a wind tunnel bench test system and a virtual wind tunnel numerical calculation model,the heat dissipation flow field of a loader engine compartment is studied,and the heat dissipation volume is optimized by adjusting the sinking amount of the fan in the windshield.The research results show that,the heat dissipation airflow increases linearly with the increase of fan speed;as the fan sinks from-30 mm to 120 mm,the total airflow passing through the radiator continues to decrease,and the heat exchange area and installation position of the radiator shall be considered comprehensively in the design of the heat dissipation system;compared to the bench test,the virtual wind tunnel numerical calculation method can be used to analyze and optimize the interior of the engine compartment in a more comprehensive and efficient way.
