Description
Technical field
The invention discloses a kind of radiator, be specifically related to a kind of air cooling heat radiator being arranged vertically changeable single double-flow.
Background technology
Indirect dry type air cooling system is made up of cooling stack and surface condenser.Recirculated water after desalination carries out twice surface-type heat exchange through condenser and air cooling heat radiator, forms closed cycle, and this system becomes the main flow of rich coal water-deficient area development electric power with its water saving and environment-friendly advantage.
Recirculated water, after condenser heat absorption, is cooled by the radiator bottom air cooling tower.Unit output becomes positive correlation with the cooling effect of air cooling heat radiator, simple employing single process condensation mode heat exchange efficiency is poor, for improving the cooling capacity of air cooling tower, the existing precision that adopts high more, the Aluminium Radiator of good cooling results, and double-flow is arranged, but because fin is thin, freezing tolerance is poor, radiator is very easily endured cold in the winter time, this not only lowers the cooling effect of system, also can cause the damage of radiator.And the renovation technique of radiator is complicated, the cycle is longer, once locally endure cold, just can expansion accident rapidly, and cause into sheet heat radiator freezing, cause huge economic loss.In the indirect air cooling unit put into operation, just once occurred that air cooling heat radiator was freezing, break and leak, these accidents gently then affect unit safety, cause unit limited load to exert oneself or unplanned outage, heavy, cause the device damage of ten million yuan.Therefore antifreeze is the most important thing of indirect air cooling unit operation.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of air cooling heat radiator being arranged vertically changeable single double-flow.
Technical scheme: for solving the problems of the technologies described above, a kind of air cooling heat radiator being arranged vertically changeable single double-flow provided by the invention, comprise radiator body, described radiator body inner upper is provided with a mixing water storage header, radiator body lower inside is respectively equipped with a water-inlet header and changeable Inlet and outlet water header, mixing water storage header is communicated with changeable Inlet and outlet water header with water-inlet header respectively by one group of fin radiator, described mixing water storage header is provided with a upper water-out pipe, described upper water-out pipe inside is provided with a upper water-out pipe motor-operated control valve, a water inlet manifold is provided with below described water-inlet header, a water inlet pipe is provided with between water inlet manifold and changeable Inlet and outlet water header, water inlet pipe inside is provided with a water inlet pipe motor-operated control valve, a lower discharging tube is provided with below described changeable Inlet and outlet water header, a lower discharging tube motor-operated control valve is provided with in lower discharging tube.
Preferably, described fin radiator is vertical parallel setting.
Preferably, described fin radiator is oval fin radiator, comprises oval single tube and is located at the fin on oval single tube.
When the air cooling heat radiator single process of the changeable single double-flow of the present invention is run, lower discharging tube motor-operated control valve is closed, the motor-operated control valve of water inlet pipe and upper water-out pipe is opened, now the changeable Inlet and outlet water header of below is as water-inlet header, recirculated water is dispensed to after each fin radiator and air carry out surface-type heat exchange by two water-inlet headers, mixing water storage header at top mixes, and flows out through upper water-out pipe; When air cooling heat radiator double-flow runs, the motor-operated control valve of water inlet pipe and upper water-out pipe is closed, and lower discharging tube motor-operated control valve is opened, and now the changeable Inlet and outlet water header of below is as going out water manifold.Recirculated water is dispensed to each fin radiator of left part by water-inlet header, is collected, after each fin radiator cooling twice of right part, collect, flow out cooling stud by lower discharging tube at the changeable Inlet and outlet water header of bottom by mixing water storage header up after Air flow.
Beneficial effect: the present invention is by the switchover operation of air cooling heat radiator list double-flow, under the environment that winter temperature is lower, antifreeze by switching to single process pattern, under the condition of other proper temperature, switches to double-flow pattern and improves heat exchange efficiency; The present invention adapts to the cooling requirement under varying environment, the problem that heat exchange efficiency when effectively solving the antifreeze problem of air cooling heat radiator winter operation and simple single process pattern is low.
