Description

The invention relates to devices that can be used as capacitors in power plants, as well as on other objects as coolers for various liquid and gaseous media.

The aim of the invention is to increase operating efficiency in a wide range of ambient temperature variations.

FIG. 1 schematically shows the cooling unit used as a condensing unit of a heat and power station, general view; in fig. 2 - installation heat exchanger device, longitudinal section.

The cooling unit contains a heat exchange device made in the form of two rows of heat pipes 1, the evaporation sections 2 of which are located in the chamber 3 for supplying a cooled medium, and the condensation sections 4 are finned 5. The condensation sections 4 are installed in the air flow air fans 6, installed between the rows of heat pipes 1. The heat pipes 1 is placed

the bones in this section of the heat pipe 1. To intensify heat transfer, atmospheric air is driven through the condensation sections 4 with the help of fans 6.

In order to increase the heat removal and reduce the dependence of the operation of the cooling unit on the outside air temperature, the cooling water from pool 7 through line 9 is supplied to distribution manifold 15, from which through channel 20 enters collection reservoir 16. The passage of cooling water through channel 20 intensifies the process the heat from the condensation plots 4 heat. out pipes 1.

With the help of nozzles 17, the cooling water is sprayed over the surface of the pool 7 and is cooled by atmospheric air supplied by the action of the vacuum generated by the fans 6.

Before operating the plant for cooling at negative outside air temperatures, the cooling water from pool 7 enters the tank 14. Under these conditions, heat is removed only by the operation of fans 6, and

a basin 7, equipped with pipe b of extremely low temperatures of the external conduits 8 and 9 with stop valves 10-13 with a cooling water storage tank 14 and a dispensing manifold 15 installed above the pipes 1. The collecting manifold 16 is fixed on the lower part of chamber 3 and additionally is equipped with nozzles 17 oriented towards pool 7. RDs of heat pipes 1 are inclined towards each other to form a channel 18 that narrows along the air movement, and in the heat pipes 1, cylindrical both are installed coaxially aiki 19 forming the through-channels 20, 16 prefabricated reporting and distributing manifolds 15. The chamber 3 for supplying the cooled medium by pipelines 21 and 22 is connected respectively to the exhaust of the turbine 23 and the condensate pump of a steam turbine unit (not shown).

The cooling unit operates as follows.

spirit - due to the natural ti gi.

Thus, due to the use in the plant for cooling a combined heat removal system during its operation at positive outside air temperatures, it is possible to maintain the calculated vacuum at the exhaust of the turbine 23 in a sufficiently wide range of outside air temperatures.
