Patent number: 11975593Abstract: A heat pump system, a heat management method and a vehicle are provided. The heat pump system includes an integrated heat exchanger integrated with a superconducting liquid flow passage and a refrigerant flow passage. The refrigerant flow passage is provided inside an on-board refrigerant circulation loop and is used for cooling and/or heating to adjust the temperature within a passenger compartment of a vehicle. The superconducting liquid flow passage is in communication with a motor heat dissipating conduit, for absorbing the heat generated by an on board motor and transferring the heat to the integrated heat exchanger by means of phase change heat transfer. The heat pump system can increase the energy utilization rate for the vehicle and reduce the allowable ambient temperature of the heat pump system.Type: GrantFiled: February 17, 2020Date of Patent: May 7, 2024Assignees: ZHEJIANG GEELY HOLDING GROUP CO., LTD., CHONGQING LIVAN AUTOMOBILE R&D INSTITUTE CO., LTDInventors: Lanbao Cao, Quankai Yang, Zhonggang Liu, Xiujuan Xu, Yanlin Liu, Guopin Tong, Chao Gao, Yanli Wang, Songyan Li, Ya Cui, Jingyu Chen, Feng Qiu, Jiaqi Zhang

Patent number: 8578313Abstract: One embodiment of the present invention provides a system that generates a pattern-clip-based hotspot database for performing automatic pattern-clip-based layout verification. During operation, the system receives a list of pattern clips which specify manufacturing hotspots to be avoided in a layout, wherein each pattern clip comprises a set of geometries in proximity to each other. Next, for each pattern clip, the system perturbs the pattern clip to determine a first range of variations for the constituent set of geometries wherein the perturbed pattern clip no longer causes a manufacturing hotspot. The system then extracts a set of correction guidance descriptions from the first range of variations for correcting the pattern clip. Subsequently, the system stores the pattern clip and the set of correction guidance descriptions in the pattern-clip-based hotspot database.Type: GrantFiled: April 24, 2008Date of Patent: November 5, 2013Assignee: Synopsys, Inc.Inventors: Zongwu Tang, Daniel Zhang, Alex Miloslavsky, Subarnarekha Sinha, Jingyu Xu, Kent Y.
