The resin mesh section allows the product to be kept in the resin case for an extended period. [Solution] The mesh portion is cylindrical with one end open and the sides closed. The case comprises an opening-holding portion that holds the entire outer circumference of one end of the mesh portion, and a frame portion that holds a part of the outer circumference of the side of the mesh portion. Multiple ribs are formed on the opening-holding portion of the case, spaced apart in the circumferential direction. The entire circumference of the opening-holding portion faces the entire circumference of one end of the mesh portion, and only a part of the circumferential direction of one end is embedded within the ribs, forming a strong coupling portion that is strongly connected to each other. In the parts other than the strong coupling portion, a weak coupling portion is formed where the mesh portion is not embedded. One end of the mesh portion and the opening-holding portion of the case are mainly connected by a pre-set strong coupling portion. Stress will concentrate between the mesh portion and the case at this strong coupling portion, but since the area where stress concentrates can be identified during the design phase, the coupling portion can be set in an area and position that will not peel off even if stress concentrates.

This application relates to the field of building equipment automation and intelligent control technology, and in particular to a distributed collaborative approximation control method and system for strongly coupled central air conditioning systems. The system includes: an equipment-level control module that establishes a local control model or optimization model based on historical operating data and real-time operating status of the equipment; a coordination layer control module that constructs and publishes coordination state variables as a virtual coordination medium to address system-level coupling constraints in the central air conditioning system; and a system-level evaluation module that collects control decisions or representation information from each equipment-level control module and evaluates the degree of satisfaction and changing trends of system-level coupling constraints. This application, by using coordination state variables as a unified coordination medium, drives each device to collaboratively iteratively approach the global optimal solution under a distributed architecture. This effectively achieves optimal overall performance and stable operation of the central air conditioning system under scenarios of heterogeneous equipment, conflicting operating objectives, or tense system constraints.

This invention provides a method for co-optimizing thermal management and signal integrity in 3D stacked packaging, relating to the field of 3D stacked packaging. The method involves acquiring heat source and signal path data, calculating the temperature field and heat flux density, identifying the intersections of thermal and electrical paths, and calculating time delay offsets.

This achieves the effect of simultaneously optimizing heat dissipation and signal integrity in 3D stacked packaging.
