The utility model discloses a sand -blast rust cleaning and roughening integration processing device for steel structure, including pressure tank: the inner chamber fixed connection of pressure tank has the baffle, the bottom fixed connection of pressure tank has the switching box, the inner chamber through -hole of pressure tank is provided with the gas pipe, the top of pressure tank inner chamber is provided with the air inlet component, the both sides of pressure tank bottom all are fixedly connected with the blanking tube that communicates with pressure tank, the both sides of switching box top all are fixedly connected with the material receiving pipe that communicates with it. The utility model discloses through the cooperation and use of gas pipe, air inlet component and feed pipe, the storage position and conveying pipeline of spraying medium are pressurized, improve the spraying intensity, and under the cooperation and use of baffle, switching box and switching component, spraying medium can be selectively used, thereby realizing the integrated use of rust cleaning, roughening function, avoiding replacing spraying medium, shortening the processing preparation step and time.

This invention discloses a heat dissipation control method and device based on the synergistic coupling of piezoelectric jet and thermoelectric cooling. The heat dissipation control method includes: controlling a piezoelectric ceramic driving plate to drive an intake flexible valve plate to generate periodic bending deformation, thereby changing the volume of the compression chamber, so that the compression chamber alternately performs the intake process and the compression process; during the compression process, when the pressure difference between the compression chamber and the external environment pressure reaches the opening threshold determined by the pre-tightening force and effective pressure area of ​​the outlet flexible valve plate, the outlet flexible valve plate passively generates an opening deformation, so that the cooling fluid in the compression chamber is injected into the air inlet of the heat exchange module in the form of a jet through the air outlet; the heat from the heat source is absorbed by the cold end of the thermoelectric cooling module, and the heat is transferred to the hot end of the thermoelectric cooling module, and then transferred to the heat exchange module, and carried away by the cooling fluid injected from the air inlet of the heat exchange module, fundamentally avoiding the risk of fatigue failure of traditional mechanical valve plates.
