Abstract: The present disclosure belongs to the technical field of heat exchangers, and provides a heat exchanger based on a Gyroid/Diamond (GD-type) hybrid minimal surface-based disturbance structure. The heat exchanger includes a core, headers, and flanges. The core includes a cold fluid channel and a hot fluid channel, the cold fluid channel and the hot fluid channel are separated by a parting sheet. An inlet and an outlet of the cold fluid channel are separated from an inlet and an outlet of the hot fluid channel by sealing bars. A GD-type hybrid minimal surface-based disturbance structure is inserted into the hot fluid channel. A cold fluid and a hot fluid are distributed in a cross-flow manner.

Abstract: A vehicle running status field model-based information transmission frequency optimization method in the Internet of Vehicles belongs to the technical field of network communications. The method establishes a running status field model according to the real-time running status of a road vehicle to describe the degree of risk of the vehicle, the degree of risk can be used to dynamically adjust the transmission frequency of safety-critical information, and the transmission frequency of non-safety-critical information is adjusted through the real-time transmission frequency of safety-critical information to achieve the purpose of improving the utilization ratio of link. The method establishes the running status field model of a moving vehicle, uses the risk intensity of the vehicle in the running status field to describe the current running risk of the vehicle, and takes account of different application scenarios, thereby having generality. In addition, the improved network resource optimization method can effectively improve the communication efficiency of heterogeneous networks, and dynamically adjust the transmission frequency of safety-critical information through the magnitude of the risk intensity to improve the utilization ratio of link.
