[0024] Please refer to Figure 2 、 Figure 3 and Figure 5 In the embodiment, a first anchor hole 10 is formed through the mounting ring 5, and a second anchor hole 11 is formed through the lid 4. The design of the first anchor hole 10 and the second anchor hole 11 eliminates the need for drilling holes during installation, reduces installation time, and improves installation efficiency. The fixed bolt 8 passes through the second anchor hole 11 and the first anchor hole 10 in sequence. The nut of the fixed bolt 8 is close to the right end of the lid 4. The fixed bolt 8 fixes the shell 1 and the lid 4 together. A limiting plate 12 is fixedly connected inside the shell 1. A hole groove 13 matching the heat pipe 6 is formed on the limiting plate 12.
