  • Publication number: 20250040095
    Abstract: A phase-change temperature regulating system and an electronic device testing apparatus and method are described. In an embodiment, the system uses a temperature regulating fluid chamber containing a temperature regulating fluid to allow the temperature regulating fluid to cover at least a part of at least one surface of an electronic component. When a temperature of the electronic component reaches a boiling point of the temperature regulating fluid, the temperature regulating fluid becomes steam through a phase change to transfer heat energy outward from the electronic component, and condenses on an inner surface of the fluid chamber to further transfer heat energy of the steam to a temperature-regulating apparatus. The condensed temperature regulating fluid flows back to the temperature regulating fluid, thereby continuously circulating.
