    打带百搭的麻将技巧:Problem consideration and decision of explosion-proof heat pipe radiator

    打麻将技巧lm0 www.wreid.com 1, explosion-proof problems


    Since the environment used by the inverter has more explosive gas or dust, this requires the inverter to be sealed and explosion-proof. Therefore, its outer casing cannot use an ordinary casing. It is necessary to use a standard explosion-proof cavity to install all the components of the inverter. In the explosion-proof cavity. Open an observation window on the explosion-proof door, mount the display part on it, and install the start, stop and speed control on the explosion-proof door. Explosion-proof heat pipe radiator


    2, heat problem


    Since all the components of the inverter are installed in the explosion-proof cavity, the air cannot flow, and the heat dissipation problem of the heat pipe radiator becomes a key problem to be solved by the inverter. Here we have adopted a new heat dissipation technology - heat pipe radiator technology.


    (1)


    Heat pipe radiator


    Technical principle


    The heat pipe is a heat transfer element with extremely high thermal conductivity. It transfers heat by evaporation and condensation of the working medium in the fully enclosed vacuum tube. It has extremely high thermal conductivity, good isothermality, and heat transfer on both sides of the hot and cold. The area can be arbitrarily changed, long-distance heat transfer, temperature control and other advantages. The heat exchanger composed of the heat pipe radiator has the advantages of high heat transfer efficiency, compact structure and small fluid resistance.


    (2) Inverter structure layout


    We designed the main circuit as a large unit, installed in the rear wall of the rectangular explosion-proof cavity. The rear wall is joined with the IGBT module, rectifier module and other heating elements through an excessive heat sink. The outer wall of the explosion-proof casing is welded with a groove-shaped heat sink to dissipate heat. The trough is connected to the trough radiator through a heat pipe. The heat generated inside the inverter is dissipated through the radiator heat sink slot on the rear wall of the explosion-proof chamber.


    3. The main circuit structure is different from the general-purpose inverter


    (1) There is no loop to avoid unsafe factors caused by sparks generated during relay operation, which increases the safety and reliability of the inverter.


    (2) The rectifier capacity selection is doubled compared with the general-purpose inverter to avoid the impact of the capacitor charging current at the moment of startup of the inverter.


    (3) Filter capacitors use multiple non-inductive capacitors. Parallel electrolytic capacitors are bulky, easy to explode and unsafe in high temperature environments; and non-inductive capacitors are small in size, resistant to high temperatures and high voltages, and are safe to use in such environments.






    25. Explosion-proof radiator features


    The explosion-proof radiator produced by our company has the following characteristics:


    1) Using a heat pipe as a heat transfer device, the reaction speed is fast, the conduction efficiency is high, and the heat dissipation effect is remarkable


    2) Using lightweight heat-dissipating fins, small size and light weight


    3) Separation of cold and heat sources, good isothermal performance, large heat transfer at small temperature difference


    4) Good flameproof performance, simple structure, convenient disassembly and assembly, and simple maintenance.
