Embodiment 1

[0030] According to an embodiment of the present invention, a circulating cooling device is provided, such as figure 1 As shown, the device includes:

[0031] The cooling pipeline 10 , the return pipeline 20 , the first heat exchanger 30 and the radiator 40 .

[0032] Wherein, one end of the cooling pipeline 10 is connected to the inlet of the radiator 40 , so that the fluid in the cooling pipeline 10 absorbs the heat of the radiator 40 ; one end of the return pipeline 20 is connected to the outlet of the radiator 40 . The cooling pipeline 10 and the return pipeline 20 pass through the first heat exchanger 30 , so that the fluid in the return pipeline 20 absorbing heat from the radiator 40 preheats the fluid in the cooling pipeline 10 . The other end of the return line 20 communicates with the other end of the cooling line 10 .

[0033] Specifically, combined with figure 1 , taking the circulating cooling device of the diverter valve as an example, since the diverter valve ...

Embodiment 2

[0040] According to an embodiment of the present invention, a circulating refrigeration device is provided, such as figure 2 As shown, the device includes:

[0041] Cooling line 10 , return line 20 , supplementary line 40 , first heat exchanger 30 , second heat exchanger 50 and radiator 40 .

[0042] Wherein, one end of the cooling pipeline 10 is connected to the inlet of the radiator 40 , so that the fluid in the cooling pipeline 10 absorbs the heat of the radiator 40 ; one end of the return pipeline 20 is connected to the outlet of the radiator 40 . The cooling pipeline 10 and the return pipeline 20 pass through the first heat exchanger 30 , so that the fluid in the return pipeline 20 absorbing heat from the radiator 40 preheats the fluid in the cooling pipeline 10 . The other end of the return line 20 communicates with the other end of the cooling line 10 . One end of the supplementary pipeline 40 communicates with the return pipeline 20 for replenishing the fluid to the...

Abstract

The invention discloses a circulating cooling device and a using method of the circulating cooling device. The circulating cooling device comprises a cooling pipeline, a return pipeline, a first heatexchanger and a radiator, wherein one end of the cooling pipeline communicates with an inlet of the radiator, so that fluid in the cooling pipeline absorbs heat of the radiator; one end of the returnpipeline communicates with an outlet of the radiator, and the cooling pipeline and the return pipeline pass through the first heat exchanger, so that fluid, which absorbs the heat of the radiator, inthe return pipeline preheats the fluid in the cooling pipeline; and the other end of the return pipeline communicates with the other end of the cooling pipeline. The circulating cooling device and theusing method of the circulating cooling device solve the problem that the circulating cooling device cannot operate normally due to pipeline freezing when the ambient temperature is low.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a circulating cooling device and a method for using the same. Background technique [0002] The power system uses high-efficiency, pollution-free, easy-to-use, and easy-to-control electric energy, which has been widely used, promoted changes in various fields of social production, created the era of electric power, and witnessed the second technological revolution. The scale and technical level of the power system have become one of the symbols of a country's economic development level. [0003] In the power system, there are many equipment such as motors, frequency converters, transformers, etc., which will emit heat during operation. In order to ensure the normal operation of the unit, it is necessary to use water cooling for cooling. However, when the ambient temperature is low, for example, when the low temperature continues in winter, there is a problem that the pip...
