The utility model discloses a kind of heat dissipation mechanisms of intelligent temperature control PCBA board, it is related to PCBA board heat dissipation technical field, including heat conducting component and combined strut, it is characterized by: the bottom four diagonally of heat conducting component is vertically installed with combined strut, and the bottom end of combined strut is connected with support frame, and the bottom middle of support frame is installed with fan mechanism component, and fan mechanism component and heat conducting component are connected with sensing line between left and right symmetry. The heat dissipation mechanism of this intelligent temperature control PCBA board, by the structural setting of heat conducting component, cooperate the structural setting of fan mechanism component, can be according to the surface temperature of PCBA board Intelligent control is carried out, and good structure heat dissipation is realized, to this end guarantee the good operation of PCBA board, simultaneously cooperate the structural setting of combined strut, can heat conducting component be fixed in the top of support frame, and cooperate the structural characteristics of support frame itself, better structure fixation can be realized, to guarantee the structural stability of PCBA board.

This application relates to a trenchless pipeline repair method, belonging to the field of pipeline repair technology. The trenchless pipeline repair method includes the following steps: S1, pipeline damage detection to determine the repair location; S2, calculation and evaluation of the pipeline damage degree to determine the required trenchless pipeline repair method; S3, calculation of the repair pipeline specifications according to the pipeline repair requirements, and pipeline repair according to the corresponding repair method; S4, post-repair testing to verify whether the repair effect is qualified. The solution provided in this application determines the pipeline repair method through pipeline operation risk level calculation and pipeline usage attributes, and calculates the repair pipeline wall based on the drainage flow, water supply flow, and pressure requirements that the pipeline should meet. This effectively shortens the pipeline repair design cycle, improves the reliability of pipeline repair, shortens the pipeline repair construction cycle, reduces the scope of construction impact and safety risks, and avoids affecting the normal operation of the airport.
