随着机床加工精度、生产效率和自动化程度的提高,使人们对机床运行时的热稳定性越来越予以重视。为此在机床设计上采用热对称结构,以及对局部热源采取各种散热措施来减小热变形,提高机床的热稳定性。 热管是一种新型高效导热元件,目前已在传热工程技术领域中受到广泛的重视。早 With the improvement of machining accuracy, production efficiency and automation, people pay more and more attention to the thermal stability of machine tools. To this end the machine tool design using thermal symmetry structure, as well as on the local heat to take a variety of cooling measures to reduce thermal deformation, improve the thermal stability of the machine. Heat pipe is a new type of highly efficient heat conduction element, which has received extensive attention in the field of heat transfer engineering. early
