Abstract

The present invention discloses a reactor parallel air cooling heat-removal system. The system comprises a cabinet body, and a machine-side reactor and a grid-side reactor arranged at the internal portion of the cabinet body, wherein the machine-side reactor is adjacent to the grid-side reactor, and the machine-side reactor and the grid-side reactor are arranged in parallel at the bottom portion of the cabinet body; the system comprises a fan and a water and wind heat exchanger; the water and wind heat exchanger is arranged at one side close to the machine-side reactor, and a wind cavity is arranged between the water and wind heat exchanger and the machine-side reactor; and the fan is fixed on the water and wind heat exchanger, and an air outlet of the fan directly faces an air inlet of the water and wind heat exchanger. The reactor parallel air cooling heat-removal system can effectively perform cooling, and is low in cost and high in reliability.

Example Embodiment

[0020] Example 1:
[0021] A parallel air cooling system for reactors, such as Figure 1~4 As shown, the cabinet 1 includes an organic-side reactor 3 and a grid-side reactor 4 arranged inside the cabinet 1, and the machine-side reactor 3 and the grid-side reactor 4 are adjacent and arranged in parallel at the bottom of the cabinet 1; also includes a fan 5 and the water-air heat exchanger 2; the water-air heat exchanger 2 is arranged on the side close to the machine-side reactor 3, and an air cavity 6 is provided between the water-air heat exchanger 2 and the machine-side reactor 3; the fan 5 is fixed On the water-air heat exchanger 3, and the air outlet of the fan 5 is facing the air inlet of the water-air heat exchanger; an air cavity 8 is formed between the air outlet of the fan 5 and the air inlet of the water-air heat exchanger 2; Several wind deflectors 7 are provided on the sides of the side reactor 3 and the grid side reactor 4 and the side of the cabinet 1 to prevent cold wind from flowing to the cabinet 1.
[0022] The cabinet 1 between the generator-side reactor 3 and the grid-side reactor 4 is also provided with a wind deflector 7 to prevent cold wind from flowing to the cabinet 1.
[0023] A gap of 5 mm-30 mm is formed between the wind deflector 7 and the above-mentioned machine-side reactor 3 and grid-side reactor 4.
[0024] The position of the wind deflector 7 arranged on the cabinet 1 is 1/2 to 4/5 of the height of the machine-side reactor 3 or the grid-side reactor 4.
[0025] The air width between the inner envelopes of the machine-side reactor 3 and the grid-side reactor 4 is 5mm-30mm.
[0026] The working mode of the parallel air-cooled heat dissipation system for the reactor provided by the present invention is as follows:
[0027] The fan 5 sucks in the hot air in the cabinet 1, and the water-air heat exchanger 2 is provided with a coolant inlet 2-1 and a coolant outlet 2-2. The hot air is sent into the water-air heat exchanger 2 to connect to the outside After the supplied cooling liquid undergoes heat exchange, it becomes cold air and enters the wind cavity 8. The cold air enters the grid-side reactor 4 and the machine-side reactor 3 under the action of the wind cavity 8 and the wind deflector 7 In the air gap 13, the cold air takes away the heat generated during the operation of the grid-side reactor 4 and the machine-side reactor 3 into hot air, which is sucked into the fan 5 and enters the next heat dissipation cycle.
