Patent number: 11953272Abstract: A cycling heat dissipation module suited for dissipating heat generated from a heat source is provided. The cycling heat dissipation module includes an evaporator, a condenser, and a micro/nano-structure. The evaporator is thermal contacted with the heat source to absorb heat generated therefrom. The condenser is connected to the evaporator to form a loop, and a working fluid is filled in the loop. The working fluid in liquid state is transformed to vapor state by absorbing heat in the evaporator, and the working fluid in vapor state is transformed to liquid state by dissipating heat in the condenser. The micro/nano-structure is disposed in the condenser to destroy a boundary layer of the working fluid while passing through the condenser.Type: GrantFiled: March 24, 2021Date of Patent: April 9, 2024Assignee: Acer IncorporatedInventors: Cheng-Yu Cheng, Wen-Neng Liao, Cheng-Wen Hsieh
