【Abstract】 Temperature control is essential for sample environments in neutron scattering experiments. A reasonable structural design is conducive to heat conduction and ensures that the experiments can be carried out effectively.A heat exchange platform for an in-house developed high voltage electric field device used in neutron scattering measurements is designed. Steady-state thermal analysis is performed on the design through ANSYS Workbench to obtain the temperature distribution of the heat exchange platform during operation. The rationality of its design is evaluated and verified through experiments to ensure the accuracy of the simulation model. The error between the calculated results and the actual test results is within 3℃. The device has been successfully tested in the China Spallation Neutron Source, providing an important basis for the further development of the electric field sample environment device with accurate temperature control.更多还原
