Description

[0002] A heat exchanger exchanges heat between cold air outside and the medium inside, condensing the steam inside or lowering the temperature of the medium. Heat exchangers that condense steam are called air-cooled condensers, while those that lower the temperature of the medium are called air-cooled radiators. Air-cooled condensers and air-cooled radiators are crucial components of the cold end of nuclear power plants.

[0021] The present invention is described in further detail below with reference to the accompanying drawings: Example 1: See also Figure 1 , this embodiment discloses a heat exchanger ventilation flow equalization device, comprising: a support frame 11, a plurality of axial sliding parts 12, a plurality of guide panels 16, a first locking part and an angle adjustment part 13; The movement direction of the axial sliding portion 12 along the support frame 11 is defined as a first direction AB; The support frame 11 is a main supporting component, providing stable structural support for the ventilation and flow balancing device of the entire heat exchanger 1 .

[0022] In the embodiment of the present invention, the support frame 11 includes two distance adjustment shafts 6 arranged in parallel, and the axial sliding portion 12 is slidably connected to the two distance adjustment shafts 6 .

[0023] In the embodiment of the present invention, the support frame 11 further includes a base, and the two distance adjustment shafts 6 are fixedly arranged on the base to further improve the stability of the device.

[0024] A plurality of axial sliding portions 12 are slidably connected to the support frame 11 and can slide along a first direction AB, allowing the position of the guide panel 16 connected to the axial sliding portions 12 to be adjusted within a certain range. The position of the guide panel 16 can be flexibly changed according to the actual size, layout, and airflow distribution characteristics of the heat exchanger 1, thereby better adapting to the airflow guidance requirements under different operating conditions and improving the versatility and adaptability of the device.

[0025] The first locking portion is used to fix the axial sliding portion 12 on the support frame 11 after the position of the axial sliding portion 12 is adjusted into place. After the axial sliding portion 12 is adjusted to a suitable position, the first locking portion can fix the axial sliding portion 12 on the support frame 11, thereby ensuring the stability of the position of the guide panel 16 and the reliability of the airflow guiding effect.

[0026] In the embodiment of the present invention, the axial sliding portion 12 includes a plane angle adjustment shaft 7 and two first sleeves 14 . The two first sleeves 14 are fixedly connected to the plane angle adjustment shaft 7 , and each first sleeve 14 is slidably mounted on one of the distance adjustment shafts 6 .

[0027] In the embodiment of the present application, the first locking part comprises a first positioning pin, a plurality of first positioning holes formed on the distance adjusting shaft 6, and a second positioning hole formed on the first sleeve 14, and the first positioning pin is arranged to pass through the first positioning hole and the second positioning hole simultaneously. When the position of the flow guide panel 16 needs to be adjusted, the first positioning pin is pulled out, so that the first sleeve 14 can slide freely on the distance adjusting shaft 6. After the position of the flow guide panel 16 is adjusted to the desired position, the first positioning pin is arranged to pass through the first positioning hole and the second positioning hole, so as to realize the fixed connection between the first sleeve 14 and the distance adjusting shaft 6.

[0028] The flow guide panel 16 is rotationally connected with the axial sliding part 12, which facilitates the adjustment of the angle of the flow guide panel 16, so as to change the flow direction of the air flow, so that the cold air can pass through the heat exchanger 1 more uniformly, effectively improves the problem of uneven air inlet of the heat exchanger 1, and improves the cooling efficiency.

The angle of the first flow guide panel 9 and the second flow guide panel 10 can be adjusted, and the first flow guide panel 9 and the second flow guide panel 10 can be parallel to each other or have a certain included angle, which assists in guiding the direction of the air flow and reduces the dead angle of the heat exchanger ventilation.

When the heat exchange capacity requirements of the groups of heat exchangers are different, the air inlet quantity needs to be adapted, the angle between the plane where the first flow guide panel 9 and the second flow guide panel 10 are located and the heat exchanger can be adjusted, the air inlet area of the heat exchanger with large heat exchange capacity is increased, and the air inlet area of the heat exchanger with small heat exchange capacity is reduced.
