Patent number: 11266042Abstract: A refrigeration system and refrigeration method for a data center are disclosed. The refrigeration system includes: a first heat exchanger disposed on a back plate of an indoor cabinet of the data center, and a phase-change heat-exchange cooling tower disposed outdoor of the data center. The first heat exchanger and the phase-change heat-exchange cooling tower are communicated by a secondary refrigerant delivery pipeline. The phase-change heat-exchange cooling tower transfers heat carried in the secondary refrigerant into air and condenses the secondary refrigerant to a liquid again; the secondary refrigerant employs a phase-change heat-exchange working medium. An air pump is disposed in the phase-change heat-exchange cooling tower and on a by-pass of the secondary refrigerant delivery pipeline to pressurize the secondary refrigerant in gas-state delivered in the secondary refrigerant delivery pipeline to increase the condensing pressure for condensing the secondary refrigerant to a liquid again.Type: GrantFiled: December 19, 2018Date of Patent: March 1, 2022Assignee: BEIJING BAIDU NETCOM SCIENCE AND TECHNOLOGY CO., LTD.Inventors: Hu Tang, Xiaozhong Li, Binghua Zhang

Patent number: 9097332Abstract: A split sprocket for belts or chains. The split sprocket comprises two sections that slide together along parallel slide tracks that are perpendicular to two opposite walls of the sprocket's bore. The slide track includes male T-shaped, V-shaped, or jigsaw-puzzle-shaped beams on one of the sections that slide into mating female slots in the other section. The mated slide tracks prevent the sections from separating in all directions except the separation direction along the slide tracks. A fastener through one of the sections into the other prevents the assembled sprocket sections from sliding apart along the slide tracks.Type: GrantFiled: April 10, 2013Date of Patent: August 4, 2015Assignee: Laitram, L.L.C.Inventors: Xiaozhong Li, Adam E. Bannerman
