设计了一种螺旋扭带式扰流强化换热装置,并对该装置的关键部件——十字固定支架和螺旋扭带进行了受力分析,获得了两部件内的应力和位移分布,证实两部件具有足够的强度,能保证装置稳定可靠地长期运行。实际应用表明,该装置能有效改善换热效果,显著提高主机的能效比。 A helical twisted band spoiler heat exchanger was designed and stress analysis was carried out on the key components of the device, such as the cross bracket and the helical twisted ribbon. The stress and displacement distribution in the two components were obtained. The parts have sufficient strength to ensure long-term stability of the device. Practical application shows that the device can effectively improve the heat transfer effect, significantly improve the host’s energy efficiency.
