Publication number: 20250180300Abstract: A heat pipe comprises a flat tube and a wick structure. The flat tube includes a hollow chamber and has two opposite sealed ends along an axial direction. The wick structure is disposed in the hollow chamber and extended along the axial direction of the flat tube. The wick structure has a smooth form with continuous edge and without the sectional difference along the axial direction. The front section is near the front sealed end, the rear section is near the rear sealed end. The smooth form has a maximum length parallel to the width direction, respectively. The maximum lengths are gradually decreased along the axial direction.Type: ApplicationFiled: February 10, 2025Publication date: June 5, 2025Inventors: Shih-Lin HUANG, Chiu-Kung CHEN, Sheng-Hua LUO, Ti-Jun WANG

Patent number: 11598585Abstract: A heat pipe comprises a tube and a wick structure. The tube includes a hollow chamber and has two sealed ends along an axial direction. The wick structure is disposed in the hollow chamber and extended along the axial direction of the tube. The wick structure has a first section near one of the sealed ends, a third section near the other of the sealed ends, and a second section between the first and third sections. The wick structure is composed of the first, the second and the third sections, and cross-sections of the first section, the second section and the third section in the axial direction are rectangles, respectively. A cross-sectional area of the first section is greater than that of the second and that of third section. The edge of each of the sections of the wick structure has a smooth form without the sectional difference.Type: GrantFiled: April 6, 2021Date of Patent: March 7, 2023Assignee: DELTA ELECTRONICS, INC.Inventors: Shih-Lin Huang, Chiu-Kung Chen, Sheng-Hua Luo, Ti-Jun Wang

Patent number: 7401638Abstract: A heat-dissipating device and its manufacturing process are provided for significantly increasing the number and size of blades so as to enhance the heat-dissipating performance. The heat-dissipating device has a plurality of blades arranged around the hub of the heat-dissipating device and there is an overlapped region formed between every two adjacent blades. A single mold is used to manufacture such a heat-dissipating device so that not only can the manufacturing cost be reduced but it can significantly increase the number and size of blades so as to increase the heat-dissipating efficiency.Type: GrantFiled: September 7, 2006Date of Patent: July 22, 2008Assignee: Delta Electronics, Inc.Inventors: Chen-Chang Lin, Wen-Shi Huang, Kuo-Cheng Lin, Sheng-Hua Luo
