How to heat the inverter

How to heat the inverter

1. Increase the power of the equipment control system components (that is, expand the capacity of the components, reduce the heat generation of the heating components, and ease the heat dissipation time between the heat source and the metal box)


   Disadvantages: slow heat dissipation, large volume, and inverter cannot be installed.


  2. Increase the heat dissipation diameter of the metal sealed box, and use a forced air-cooled fan to force heat dissipation of the metal sealed box.


   Disadvantages: high production costs, difficult maintenance, and inverters cannot be installed.


  3. Increase the water channel coil of the metal sealed box to allow the water to take away the heat of the metal sealed box when the water passes through the water channel.


   Disadvantages: high production cost, difficult maintenance, frequent replacement of large amounts of cooling water.


  4. Heat pipe heat dissipation, close the heating element in the metal sealed box to one end of the heat pipe of the box, and use the medium in the heat pipe to transfer heat to the outside of the metal sealed box.


   Disadvantages: Disadvantages: large size, high production cost, difficult maintenance, high requirements for the use environment temperature (must be below 25 ℃, generally used in the mine).


The main reason for the main disadvantage is that the thick metal sealed explosion-proof box must be used as the medium to exchange the internal heat to the outside, and although the latter uses forced air cooling, forced water cooling, and heat pipe media, the speed of heat exchange is still It is far from meeting the working environment requirements of industrial equipment control systems in the explosion-proof field (slow heat dissipation, easy aging of components, short service life), and the above working principle is only heat dissipation.
