Paper Abstract

In this paper, based on the fundamental theories of heat transfer, we researched the cooling characteristics of a finite Nd: GGG slab working in HCL mode. The 3D thermal and stress fields in the slab are simulated by the ANSYS firstly, then distribution rules of temperature and stress are outlined, and the influences of coolant temperature and convective heat transfer coefficient on the cooling effects are also discussed. At last, a cooling method with increasing continuously flow rate coolant in normal temperature is proposed. As a result, the maximum cooling stress could be depressed down about ten percents and cooling procedure is also shortened. It can be suitable to some special SSHCLs' applications that have higher demand for cooling time.
