  • Patent number: 11909744
    Abstract: A network verification system obtains configuration data of a plurality of network devices, where a data model of the configuration data is described by using a general data modeling language independent of the network devices; and the network verification system verifies data links between the plurality of network devices based on the configuration data of the plurality of network devices and a topology structure between the plurality of network devices. The network verification system verifies the data links between the plurality of network devices based on the topology structure between the plurality of network devices and the configuration data described by using the general data modeling language independent of the network devices. This helps improve scalability of the network verification system and avoids relatively poor scalability of network simulation software that occurs when conventional network simulation software provides a template for configuration data of each type of network device.

  • Publication number: 20230111700
    Abstract: A heat exchanger includes a collecting pipe, a number of heat exchange tubes and a distributor. The collecting pipe has a first cavity and a first inner peripheral wall. The heat exchange tube has a second cavity. The distributor is accommodated in the first cavity. The distributor has a main cavity and a flow channel. The distributor includes a second inner peripheral wall forming the main cavity and a first outer peripheral wall. An axis of the first outer circle is not coaxial with an axis of the second outer circle, so that the flow channel of the distributor is relatively tortuous. It is beneficial to improve the distribution effect of a fluid. Besides, since the flow channel is formed inside the distributor, it is also beneficial to reduce the manufacturing difficulty of the distributor. A method for making the heat exchanger is also disclosed.

  • Publication number: 20220325956
    Abstract: The present disclosure discloses a heat exchanger including a group of collecting pipes and a number of heat exchange assemblies. Each heat exchange assembly includes a fin plate and at least one heat exchange tube. The heat exchange assembly includes a main heat exchange area. The heat exchange tube is connected with the fin plate. The heat exchange tube at least partially protrudes from at least one side of the fin plate. In addition, in the main heat exchange area corresponding to two adjacent heat exchange assemblies, at least two adjacent heat exchange tubes are staggered along an array direction of the heat exchange assemblies. The two heat exchange tubes respectively belong to the two adjacent heat exchange assemblies. The present disclosure is beneficial to improve the performance of the heat exchanger.
