[0025] The high heat dissipation mounting housing includes:

[0026] The housing has an internal mounting cavity 3 and a heat dissipation part 21 with a through heat dissipation hole 211 on one side. The inner wall of the heat dissipation part 21 has a heat-conducting boss 22 protruding. The mounting cavity 3 is used to install a primary circuit board 7 and a secondary circuit board 8 with a spacing corresponding to the primary circuit board 7, which are sleeved on the outer periphery of the heat-conducting boss 22 and form a heat dissipation area 23 between the primary circuit board 7 and the secondary circuit board 8.
