When the body loses its soul, the body will collapse. From the fundamental aspect of safety, transformation and upgrading control is equivalent to cutting off unsafe factors of objects, thereby reducing the occurrence of failures. The following is a schematic diagram of the upgrading of York Quantum Control Center.: Currently, the oldest controller, the Quantum 4 controller, has been used for a long time and has a harsh environment, resulting in frequent black screen control, undetectable data, and other parking failures. This situation is a potential failure and accident hazard, and is likely to cause the compressor to shut down during the production process. At present, the York manufacturer has stopped production of Quantum 4, and the latest controller is Quantum HD. Upgrading is relatively easy, replacing the main board (including program), touch screen, input and output board, analog board, module power supply, analog input wiring, switch input, relay output, etc. The debugging phase requires input of a large amount of setting data, calibration of slide valves and sliders, etc. Notice: You must wear an electrostatic bracelet. Below is a picture of the replacement of the positive pressure explosion-proof cabinet refrigerator.
In such a harsh working environment, is it necessary to install a small fan in and out to introduce an air duct design to improve the heat dissipation conditions of the motherboard and make the equipment more durable?

The positive pressure explosion-proof control cabinet does not generate much heat. The motherboard is just like a computer. If the temperature is high, it is the CPU. The power is not high. There is an aluminum radiator on the CPU (as you can see from the picture). The entire control circuit is in a closed environment, using nitrogen to create a positive pressure and dry environment. Generally used in flammable and explosive environments.
The first picture has the EX mark. Because the refrigerant is propane, it is flammable and explosive. The motor is a high-voltage explosion-proof motor
There is an EX mark on the control box~~~
