Patent number: 11913735Abstract: A heat exchanger includes a collecting pipe, a number of heat exchange tubes and a distribution pipe. A pipe wall of the distribution pipe defines a number of through holes communicating with the collecting pipe. The through holes are a first through hole, . . . an (n?1)th through hole and an nth through hole disposed in sequence along a direction from a first end to a second end of the distribution pipe. A distance between an (i+1)th through hole and an ith through hole is: di=?iL0, i=1, 2, . . . n?1, ?=0.618, L0 is a distance between adjacent heat exchange tubes. As a result, uniformity of refrigerant distribution in the heat exchanger is improved.Type: GrantFiled: May 25, 2021Date of Patent: February 27, 2024Assignee: HANGZHOU SANHUA RESEARCH INSTITUTE CO., LTD.Inventors: Zhaogang Qi, Linjie Huang, Qiang Gao, Jianlong Jiang, Yujiao Niu, Chunyu Shao

Patent number: 11892251Abstract: A heat exchanger has a collecting pipe, a separator and a number of heat exchange tubes. The collecting pipe has a pipe wall and an inner cavity. The separator is provided in the inner cavity. The separator extends along a lengthwise direction of the collecting pipe. The separator divides the collecting pipe into a first cavity and a second cavity. The heat exchange tubes are arranged along the lengthwise direction. Each heat exchange tube has a first end and an inner cavity. The first end of the heat exchange tube sequentially passes through the pipe wall of the collecting pipe, the first cavity and the separator to be inserted into the second cavity. The inner cavity of the heat exchange tube is communicated with the second cavity. As a result, uniformity of refrigerant distribution in the heat exchanger is improved.Type: GrantFiled: May 25, 2021Date of Patent: February 6, 2024Assignee: HANGZHOU SANHUA RESEARCH INSTITUTE CO., LTD.Inventors: Zhaogang Qi, Linjie Huang, Qiang Gao, Jianlong Jiang, Yujiao Niu, Chunyu Shao

Publication number: 20220163245Abstract: A gas-liquid separation device includes a cylinder, an external port, an adapter, and a gas-liquid separation component. The cylinder has a first cavity, a second cavity, and a third cavity. The external port includes a first port, a second port, and a third port. The adapter is at least partially disposed in the cylinder. The gas-liquid separation component is located in the third cavity. When the gas-liquid separation device is in a first working state, the adapter separates the third port from the third cavity, the first port serves as the inlet, and the second port serves as the outlet when the gas-liquid separation device is in a second working state, the adapter communicates the third port with the third cavity, the second port serves as an inlet, and the first port and the third port serve as outlets. The gas-liquid separation component separates gas-liquid two-phase refrigerant.Type: ApplicationFiled: March 11, 2020Publication date: May 26, 2022Inventors: ZHAOGANG QI, CHUNYU SHAO, LINJIE HUANG

Patent number: 11099163Abstract: Embodiments relate generally to systems and methods for calibrating a gas detector. Some embodiments may include a gas detector comprising one or more sensing elements operable to detect volatile organic compounds (VOC), and a probe operable to provide air flow into the gas detector, wherein the probe comprises: a housing operable to attach to a main body of the gas detector and operable to hold a calibration tube during calibration of the gas detector; a cap operable to attach to the housing and operable to fit over and cover the calibration tube; and one or more inlets, wherein when a calibration tube is inserted into the probe, the air flows through the calibration tube. In some embodiments of the gas detector, the calibration tube inserted into the probe comprises activated carbon fiber (ACF) filter material.Type: GrantFiled: April 23, 2019Date of Patent: August 24, 2021Assignee: Honeywell International Inc.Inventors: Chunyu Shao, Nico Xu, Kevin Chen, Sam Su, Yong Chen
