Oil Cooling
Oil-cooled systems are used widely in the first rectifier to the present day. Foreign influences the required protection devices appears as a good solution. The removal of heat from the device structures used in the tank is provided in various formats. The basis of the system affected all parts of its oil from an oil tank, oil tank outside the walls of the heat of immersion and to give up. Provides a special heat transfer oil, but oil is used as electrical insulator.Oil, in which almost all the parts in contact with the point. Escaping the heat passes through oil and grease will cause it to overheat. Heat the oil in the oil tank outside the walls of metal passes through the air.Heated oil in the tank rises to the next level goes colder than the lower levels of the fat. In this way, a natural circulation can be ensured. In proportion to the amount of used oil, heating oil is a specific time. In this case the temperature of the oil until it reaches a certain degree of cooling of the device as a natural means.In other words, temperatures in parts of the device are synchronized with oil until the oil temperature, the heat will continue to receive parts. For example, working eight hours a day running a business periodically consider a device.Sufficient amount of oil, the oil temperature in the morning until the end of overtime, but the upper limit is reached. If the device does not work in the oil is cooled down until the morning. Thus the cycle continues the next day.However, a device for busy people and the oil temperature rises more quickly with the same temperature, the components in the rectifier becomes no longer cooler.After this point the situation worsens and the oil device continuously attempts to hot-held device to reveal any further increase in temperature causes the heat. This is an undesirable condition for the cooling system. Prevent growth from becoming harmful heat and cooling is used to sustain the various types of tanks. Due to the passage of heat into the air in the tank to last the contact surface to expand with air cooling process creates a beneficial effect.The walls of a tank of air in contact with a flat surface, but the total surface area of the tank would be. Whereas the outer walls made of intricate or the addition of slices of the surface area of the radiator to the tank allows the increase of up to several times normal. The most common of the two types of wall and radiator Sliced Wave tanks. Sliced radiator tanks are manufactured from the normal straight hair. Side surfaces of the radiators to allow the tank to connect to the upper and lower level of the oil flow channels are created. Slices in the radiator is connected to these channels. As mentioned earlier, radiator-heated oil flows into the next level of interest and the upper channel.Sub-channel through the radiator cooling oil returns to the tank again. Thus, a cooling system that allows their circulation is achieved. Heat will be used to reveal the number of slices is chosen. Wave type of tank wall, the outer surfaces of the fins outward created. The surface area of fins can be increased 3-4 times. Such an increase in the numbers is very effective cooling. Also increases the amount of the capacity of the tank will increase oil used.Heat transfer fins in the air makes more amounts of oil. Thus, rapid temperature rise of the oil would be increased. Rectifier will provide sufficient cooling for most of a tank are calculated correctly. Heavy-duty systems running without interruption, the oil is cooled hybrid systems are used in algebra. Oil-cooled systems, the most important advantage is thatall kinds environmental conditions preserved . Acid vapor, especially in facilities where there is available for many years without any problems. However, the extra oil costs, the disadvantages of the service and maintenance challenges.Remaining in the tank system, the device may occur in cases of failure of the device from oil extraction is a laborious and time-consuming process. In addition, the extra oil costs over time will mean the loss of the oil property. |
