1. Overview of air (air) water cooling device products:

Air-water cooling device is a high voltage inverter cooling equipment system integrating environmental protection and energy saving. In the power, steel, cement, coal, chemical, petroleum, metallurgy and other industries of high voltage high power inverter project has been widely promoted and applied, high voltage frequency converter cooling equipment system fundamentally solves the problems of high unit heat dissipation density, high energy consumption of equipment. It is of positive significance to improve the safety and reliability of the system, reduce the operating cost, and maximize the benefits of the high voltage frequency conversion energy saving project.

2. Model meaning:

3. way to install:

The air-water cooling device can be installed outdoors or indoors according to the field conditions, and connected to the high voltage inverter cooling equipment cooling fan through the air duct. The heat generated during the operation of the frequency converter is directly recovered by the air-water cooling system, and then discharged to the indoor after heat exchange.

4. Basic principle of air (air) water cooling device:

The hot air of the converter is then directly exchanged through the air-water cooling device, and the heat lost by the converter is directly removed by the cooling water; the cooling cold air is discharged back to the room. The cold water temperature in the air-water cooling device is lower than 33℃, that is, the hot air indoor ambient temperature in the frequency converter can be controlled below 40℃ after the heat sink, which meets the requirements of the frequency converter for environmental operation, so as to ensure a good operating environment in the frequency converter room.

5. Characteristics of air (air) water cooling system:

1. The system has the characteristics of low energy consumption, high cooling capacity and gale volume;

2. The operating cost of the system is 1 / 3~1 / 4 of the air conditioner with the same heat exchange power;

3. In the case of failure, ventilation cooling can be used without affecting the operation of the equipment;

4. Low initial investment and cost saving;

5, the equipment installation is simple and fast;

6. Low failure rate and reliable performance of the equipment;

7. Long service life and low maintenance capacity of the equipment;

8, indoor closed cooling, less dust, clean and hygienic, low maintenance of frequency converter.

Vi. Working conditions and cooperation matters:

1. The supplier shall be responsible for the equipment installation guidance after the equipment arrives at the site.
