In the electronic and electrical industry, high-frequency rectifier is a kind of rectifier with small volume, light weight and high efficiency. It is used in various precision surface treatment places such as electrolysis, experiment, oxidation, zinc plating, corrosion, etc.
In general, during the operation of high-frequency rectifier, the coil will emit a lot of heat, which will seriously affect its operation. Poor heat dissipation will cause the rectifier to heat up, reduce its performance, and even cause electrical accidents.
Generally, the temperature of the rectifier is required to be above 5 ° C and below 30 ° C. During the normal operation of the high-frequency rectifier, air cooling or air cooling, water cooling and oil cooling are usually used. These two methods are widely used.
How to equip high frequency rectifier with chiller?
Generally, the rectifier power * 0.86 shall be determined according to the size of rectifier, and then the specification and type of chiller can be selected according to the refrigeration range of chiller.
Generally, the standard water chiller is equipped with a cooling capacity of 1-2 horsepower. The air-cooled water chiller is used to make cold water, and then the built-in water pump circulates the cold water and hot water with the built-in cooling pipe of the high-frequency rectifier to take away the working heat and achieve the goal of cooling.
What are the advantages of air-cooled chillers?
1. Air cooled chillers have reliable protective devices to prevent equipment from being too long or improperly operated, which may cause unit failure. Generally, they are equipped with phase loss/inversion device, compressor overload device, water shortage alarm, high and low pressure protection device, etc. The low temperature/anti ice protection device can start the protection device at the first time to avoid further damage to the chiller.
2. Temperature control of air cooled chiller.
Precise Whether it is an air-cooled modular chiller or an integrated screw chiller, it can meet the temperature requirements of various refrigeration industries, from 30 ° C to - 50 ° C, or even below - 50 ° C. The heat dissipation of high-frequency rectifier is completed by setting on the manual temperature regulation control panel.
3. Application of energy-saving and environmental protection technology.
Power loss is the characteristic of all mechanical equipment. Under the condition of ensuring performance, try to use the configuration configuration of frequency conversion, power saving and energy saving, or the operation mode, which is conducive to energy saving and cost saving of equipment.
The air-cooled chiller can be customized with frequency conversion and adopts high-quality heat dissipation materials, which is conducive to the overall energy saving of the equipment.
