The core and complex part of the heat exchanger core is the connecting pipe, and each heat exchanger has a unique pipeline connection method, as shown is one type of pipeline connection.
The information regarding connection methods is stored in the simulation software in a specific format. The information on connection methods stored within the program is arbitrary, and the structural information stored cannot be directly used in drafting software. Drawing connection pipes requires determining specific spatial structural parameters. Therefore, the difficulty with the heat exchanger core plug lies in decoding the information of arbitrary connection methods into the specific parameter coordinates needed for writing SolidWorks drafting functions.
