  • Publication number: 20240164059
    Abstract: A vapor chamber structure includes an aluminum upper plate, an aluminum lower plate, a working fluid and multiple micron-sized recesses. The aluminum upper plate has a first side and a second side. The aluminum lower plate has a third side and a fourth side. The aluminum upper and lower plates are correspondingly mated with each other to define an airtight chamber. The working fluid is filled in the airtight chamber. The micron-sized recesses are directly formed on the third side. The micron-sized recesses are upward raised and/or downward recessed from the third side in the form of multiple small puddles so as to enhance the boiling efficiency of the working fluid in the airtight chamber and promote liquid-vapor circulation performance of the vapor chamber. In addition, when used in a low-temperature environment, the vapor chamber structure prevents the working fluid in the airtight chamber from freezing.

  • Patent number: 11864349
    Abstract: A vapor chamber with structure for enhancing two-phase flow boiling includes a main body formed of a first and a second plate member, which are correspondingly closed to each other to define an airtight chamber between them. The airtight chamber has a condensing side and an evaporating side and has a working fluid filled therein. The evaporating side is formed on its surface with a plurality of projected sections and a plurality of recessed sections and has a wick structure provided thereon. The projected sections extend through and project beyond the wick structure, and the recessed sections are located below the wick structure without being filled by the wick structure to thereby form spaces for receiving the working fluid. The provision of the projected and the recessed sections enables the vapor chamber to provide largely enhanced two-phase flow boiling effect in the airtight chamber.

  • Publication number: 20220283106
    Abstract: A heat source simulation structure includes a heating body and a heating member to form a simulation heat source main body for conducting heat. The simulation heat source main body is enclosed in an outer case and a heating substrate with electrical insulation and heat insulation properties to avoid dissipation of the heat. The heating member is electrically connected with an external power supply for heating the heating body. A thermocouple member is disposed on the heating body corresponding to the heating member. A temperature monitoring port is connected with a data collection meter for recording the temperature of the heating body. By means of the heat insulation design enclosing the simulation heat source main body, the contact thermal resistance between the heating member and the heating body is reduced, further to lower the heat loss of the heat source simulation structure and enhance the measurement precision and reliability.
