Problems solved by technology

[0002] At present, in the evaporative cooling type external cooling system of the existing DC converter station, the circulating water pump is manually started to realize the circulation of cooling water and spray cooling, which is time-consuming and laborious, with low work efficiency and serious waste of resources, and it is difficult to automatically cool the cooling water. Carry out circulating transportation and cooling, and the cooling method of cooling water is single, the cooling efficiency is not high enough, the effect is poor, and it is very inconvenient to use

Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0028] refer to Figure 1-7 , an evaporative cooling type external cooling system for DC converter stations, including a heating component 2, a first cooling water pipe 3 spirally surrounds the outer side of the heating component 2, a hollow storage disk 4 is arranged on the top of the heating component 2, and the hollow storage A thermal expansion fluid 31 is arranged inside the disk 4, and the thermal expansion fluid 31 is kerosene. When the thermal expansion fluid 31 is heated, its volume will increase. One side of the heating element 2 is provided with an external cooling tower 1, and a hollow cooling tower 1 is fixedly installed on the outside of the external coo...

Abstract

The invention discloses an evaporative cooling type external cooling system for a direct current converter station, which comprises a heating assembly, a first cooling water pipe spirally surrounds the outer side of the heating assembly, a hollow storage disc is arranged at the top of the heating assembly, and thermal expansion liquid is arranged in the hollow storage disc; an outer cooling tower is arranged on one side of the heating assembly, and a hollow cavity, a water storage tank and a water supplementing tank are fixedly installed on the outer side of the outer cooling tower. According to the invention, cooling water in the first cooling water pipe, the circulating chamber and the second cooling water pipe can be automatically exchanged when the temperature of the heating assembly is relatively high, self-circulation of the cooling water is realized, the heating assembly is cooled, the use is convenient, the second cooling water pipe can be automatically sprayed and blasted after the cooling water is exchanged, heat exchange is accelerated through evaporation of spraying water, and the cooling effect is better. The system is suitable for converter stations.

Description

technical field [0001] The invention relates to the technical field of evaporative cooling, in particular to an evaporative cooling type external cooling system for a DC converter station. Background technique [0002] At present, in the evaporative cooling type external cooling system of the existing DC converter station, the circulating water pump is manually started to realize the circulation of cooling water and spray cooling, which is time-consuming and laborious, with low work efficiency and serious waste of resources, and it is difficult to automatically cool the cooling water. Carry out circulation conveying and cooling, and the way of cooling the cooling water is single at the same time, the cooling efficiency is not high enough, the effect is poor, and it is very inconvenient to use. Contents of the invention [0003] The object of the present invention is to solve the shortcomings in the prior art, and propose an evaporative cooling type external cooling system ...
