Patent number: 11476514Abstract: An integrated cooling assembly includes a cooling assembly and a valve assembly. The cooling assembly has a first interface and a second interface. The valve assembly includes a connecting block and a valve core assembly. The connecting block has at least a mounting hole for mounting the valve core assembly, and a first port and a second port in communication with the mounting hole. The second port is located on an inner end surface of the connecting block. The inner end surface faces the cooling assembly. The first interface is in communication with the second port. The valve assembly comprises a first fluid channel. One end of the channel is the first port of the connecting block, and the other end is the second port. A channel passage area of the first fluid channel switches between zero and a specified passage area of the first fluid channel.Type: GrantFiled: September 18, 2018Date of Patent: October 18, 2022Assignee: Zhejiang Sanhua Automotive Components Co., Ltd.Inventors: Rongrong Zhang, Jiang Zou, Zhenshan Zhu
