This utility model discloses a multi-directional heat dissipation fin structure for a power battery terminal, including a mounting base and a heat dissipation fin assembly. The mounting base is a hollow cylindrical structure for fitting into the terminal. At least two heat dissipation fin assemblies are provided. These fin assemblies are evenly spaced from top to bottom on the outer wall of the bushing, creating horizontal gaps between adjacent fin assemblies for airflow. Each heat dissipation fin assembly consists of multiple fins, which are evenly distributed circumferentially on the outer wall of the mounting base, creating vertical gaps between adjacent fins for airflow. This increases airflow efficiency while maintaining sufficient heat dissipation area, effectively reducing the terminal temperature and ensuring battery performance and safety.

The utility model discloses a tempered laminated hollow LED reverse pasting lamp photovoltaic glass, relates to the photovoltaic glass technology field, and comprises an installation assembly, the installation assembly comprises a PVB film, an aluminum heat radiation sheet, via holes, an installation support, heat conduction silicone grease, a clamping groove and an LED chip, the aluminum heat radiation sheet is pasted on the back side of the PVB film, the via holes are arranged on the PVB film in an array mode, and the installation support is provided with the LED chip. A mounting bracket penetrates through the interior of the via hole, and heat-conducting silicone grease is filled in a gap between the mounting bracket and the via hole. According to the tempered laminated hollow LED reversely-pasted photovoltaic glass provided by the invention, the PVB film with high mechanical strength is selected as the substrate to enhance the deformation resistance, and the heat conduction silicone grease is filled in the gap between the mounting bracket and the via hole in the PVB film, so that the heat generated during the operation of the LED chip is conducted to the aluminum cooling fin on the back surface of the PVB film through the heat conduction silicone grease; the heat dissipation area can be effectively guaranteed, the heat dissipation performance is improved, meanwhile, the sealing performance of the connecting position can be guaranteed, and rainwater and impurities are prevented from permeating.
