Novel multifunctional heat exchanger of fracturing truck with three-dimensional finned tubes

Abstract

The invention discloses a novel multifunctional heat exchanger of a fracturing truck with three-dimensional finned tubes. The novel multifunctional heat exchanger comprises the three-dimensional finned tubes, wherein the three-dimensional finned tubes are divided into three upper and middle and lower layers which are horizontally arranged at intervals, the adjacent three-dimensional finned tubes in each layer are horizontally and uniformly arranged at intervals, the left inlet ends of the three-dimensional finned tubes respectively communicate with one steam dispersion bin, the right outlet ends of the three-dimensional finned tubes respectively communicate with one condensation water bin, the steam dispersion bin is connected with a steam conveying pipe, the condensation water bin is connected with a condensation water outlet pipe, cold water spray pipes are horizontally arranged below the lower three-dimensional finned tubes at intervals, atomization spray holes are uniformly arranged on the top pipe bodies of the cold water spray pipes at intervals, a bellows with a shutter is arranged below the cold water spray pipes, a horizontal fan which is driven by a motor is arranged in the bellows, and the working surface of the horizontal fan is parallel to the three-dimensional finned tubes. The device has the advantage of high heat exchange efficiency, and normal operation of equipment in same working conditions can be guaranteed; the size of the heat exchanger is greatly reduced, so that the weight of the fracturing truck is reduced.

Description

technical field [0001] The invention relates to a novel three-dimensional rib tube multifunctional heat exchanger for fracturing vehicles, which belongs to heat exchange equipment used in oil field fracturing vehicles. Background technique [0002] The newly put into production wells in the Mahu Oilfield require large-scale fracturing operations. At present, there are problems with fracturing trucks in high temperature weather: due to the existing heat exchange system of the fracturing truck, the heat exchange efficiency is poor, and the operation in high temperature weather is prone to insufficient heat exchange capacity. , causing the fracturing pump to often shut down due to high temperature; the heat transfer efficiency of the existing heat exchanger is poor, and the influence of the ambient temperature difference is large. When the ambient temperature is high, spray cooling is required to ensure the normal operation of the fracturing pump truck; the existing heat exchang...

[0002] The newly put into production wells in the Mahu Oilfield require large-scale fracturing operations. At present, there are problems with fracturing trucks in high temperature weather: due to the existing heat exchange system of the fracturing truck, the heat exchange efficiency is poor, and the operation in high temperature weather is prone to insufficient heat exchange capacity. , causing the fracturing pump to often shut down due to high temperature; the heat transfer efficiency of the existing heat exchanger is poor, and the influence of the ambient temperature difference is large. When the ambient temperature is high, spray cooling is required to ensure the normal operation of the fracturing pump truck; the existing heat exchanger is large in size , causing the weight and volume of the fracturing pump truck to greatly exceed the standard, which affects the road driving and field operation performance of the whole vehicle; the existing heat exchanger is a copper plate-fin heat exchanger, and the fins are welded, which is time-consuming The processing cost of waste materials is high, and the welding points are easy to fall off, causing the heat exchanger to be easily damaged and leaked; the existing heat exchanger is a copper plate-fin heat exchanger, and the medium flow space is small, which is easy to cause blockage of the heat exchange channel; the fins are It is welded and processed, which is inconvenient for inspection and maintenance; the existing heat exchanger is large in size and high in weight, and it is inconvenient to hoist, repair, and maintain; Inconvenient; the heat exchange efficiency of the existing heat exchanger is low, and the required heat exchange performance under the same working conditions is large in size, and the forced cooling fan that needs to be used is large in size, high in power, and high in energy consumption
