Gas flows through the gap, and at the same time, the return spring is compressed to achieve communication between the first connecting part 21 and the second connecting part 22. When the support plate 13 is moved, the support plate 13 drives the second connecting part 22 to move. At this time, under the action of the elastic component 2107, the plug 2105 is pushed to contact the annular sealing plate 2104, realizing the automatic closing of the first connecting part 21.

[0051] The working principle of this utility model is as follows: the support plate 13 is pushed to move along the sliding groove of the sliding frame 7. The support plate 13 drives the second connecting part 22 and the second connecting part 22 to seal and contact. By rotating the limiting bolt 8, its end is inserted into the limiting hole 16, sealing the first connecting part 21 and the second connecting part 22. The fan 6 is started to send gas through the sealed connecting cavity 11, the main gas supply pipe 10, and the branch gas supply pipe 12 into the first connecting part 21. Then, the gas enters the gas supply cavity 18 through the second connecting part 22 and is discharged through the exhaust nozzle 19. This provides precise heat dissipation for the power distribution equipment on the mounting frame 14 and finally discharges through the corresponding exhaust port 4.

[0052] The second connecting cavity 2201 on the second connecting part 22 is moved by the support plate 13, so that the second connecting cavity 2201 contacts the first connecting cavity 2101. At the same time, the conical cylinder 2203 is inserted into the conical groove 2103 to achieve a sealed connection between the first connecting cavity 2101 and the second connecting cavity 2201. The spherical groove 2206 of the push rod 2205 contacts the spherical head 2106, and the spherical head 2106 pushes the plug 2105 to move along the annular sealing plate 2104, so that a gap is created between the plug 2105 and the annular sealing plate 2104. Gas flows through the gap and compresses the return spring, realizing the connection between the first connecting part 21 and the second connecting part 22. When the support plate 13 is moved, the second connecting part 22 is moved by the support plate 13. At this time, under the action of the elastic component 2107, the plug 2105 is pushed to contact the annular sealing plate 2104, realizing the automatic closing of the first connecting part 21.
