The invention discloses a novel mobile air-water cooling speed control device. The device comprises a housing, a high-voltage frequency converter installed at the bottom of the housing, a partition arranged on the top of the high-voltage frequency converter and dividing the housing into a hot air area and a cold air area, an air cooler installed on the partition and located at one side of the high-voltage frequency converter, an air outlet and an air inlet arranged at the two ends of the housing respectively, an air outlet fan installed on the air outlet, an air inlet fan installed on the air inlet, and a water leakage detection device installed at the bottom of the air cooler and located at one side of the air inlet fan. The air cooler comprises a booster fan and a condensation pipe arranged at the bottom of the booster fan. Both the air outlet fan and the air inlet fan are equipped with manual switches. Through the air cooler, cold and hot air can circulate in the housing, and the mode of circulation is not limited by external conditions. Lifting lugs installed at the two sides of a beam at the bottom of the housing make the high-voltage frequency converter easy to carry. The device has a simple structure, and the maintenance cost and production cost of the high-voltage frequency converter are reduced.
Description
technical field [0001] The invention relates to the technical field of heat exchange, and more specifically relates to a novel mobile air-water cooling speed regulating device. Background technique [0002] In the process of oil production in oilfields, water injection, as one of the important methods of increasing production, has been widely used in oilfields. Since oil fields use high-pressure water injection pumps for water injection, and high-pressure water injection pumps require high-power motors, high-voltage frequency converters are essential components in the water injection process. [0003] In addition, due to the general installation environment requirements of high-voltage inverters: the minimum ambient temperature is -5°C, the maximum ambient temperature is 40°C, and the failure rate of high-voltage inverters will increase exponentially with the increase of temperature, so high-voltage inverters A cooling device is required during operation. However, due to t...
