Description

oo oo VI

o a The invention relates to heat engineering, especially to heat exchangers with forced convection, and can be used in the regulation of surface heat exchangers. The purpose of the invention is to intensify heat transfer. The drawing shows the block diagram of the device for regulation and the object of regulation,. The control object is a tubular heat exchanger 1, which is made up of a bundle of tubes 2 (one tube is shown) with a turbulizer, filled in the form of elastic rings, mounted into the wall of each tube and having internal 3 and outer 4 parts connected to pipeline 5 supply of energy, and pipeline 6 supply of the working medium. The turbulator can also be made either with an external one, or only with an internal part. The device consists of a sensor 7 of the temperature of the working medium at the exit of the heat exchanger, sensors 8 and 9 of the temperature of the energy carrier, the regulator 10 of the energy carrier consumption, the actuator - the valve 11 installed in the pipeline of the energy carrier supply, the adder 12, the extreme regulator the configuration of the turbulizer and consisting of a pneumatic cylinder 14 and a plug of 15 connected to the pipe 2, the device operates as follows. The signal from sensor 7 is fed to the input of the regulator 10, acting on the actuator-valve II, and changes the consumption of energy by reducing the latter when the temperature of the working medium increases or, per revolution, increasing when the temperature of the working medium decreases, until it reaches the specified value. The signals from sensors 8 and 9 are fed to the input of the adder 12, where they are compared, and the difference is fed to the input of the extreme regulator 13, acting on the pneumatic cylinder 14 connected through cable 15 to the pipe 2, and changing the configuration of the elastic turbulator, ensuring the maximum possible at the current value of the energy carrier and working medium, the magnitude of the signal difference from the adder 12. &
