Abstract: Embodiments of this application disclose a thermal management apparatus and an energy storage system for improving space utilization of the thermal management apparatus and minimizing the volume of the thermal management apparatus. The thermal management apparatus includes a cabinet, a fan, a first heat dissipation module, and a second heat dissipation module. The fan is disposed on a top surface of the cabinet. Each of the first heat dissipation module and the second heat dissipation module is a plate structure. An included angle between the first heat dissipation module and the top surface is unequal to an included angle between the second heat dissipation module and the top surface.

Abstract: This application provides a method for measuring a dynamic thermal expansion property of a nano-film, and relates to the technical field of measurement. The method is applied to an ellipsometer equipped with a temperature-controlled heating stage. The method includes: controlling a temperature of a film sample on the temperature-controlled heating stage according to a resonant temperature modulation program, and obtaining a thickness-time curve of the film by using the ellipsometer; determining, by using a digital signal processing method based on the obtained thickness-time curve, an amplitude and a phase of a resonant dynamic change generated for a thickness of the film in response to the temperature modulation program, to obtain an amplitude-time curve and a phase-time curve; and further determining a coefficient of apparent thermal expansion, a coefficient of reversible thermal expansion, and a coefficient of irreversible thermal expansion for the film sample.
