At the same time, the second support rod 5 slides in the groove 4 to shorten the overall length between the first support rod 3 and the second support rod 5. Finally, the locking assembly is used to lock and position the bases 1, the baffles 2, and the first support rod 3 and the second support rod 5. As the heat exchange area in the heat exchange module decreases, the distance between the bases 1, the baffles 2, and the first support rod 3 and the second support rod 5 are adjusted, thereby reducing the footprint of the overall device and improving ease of use.

[0033] When the heat exchange area of ​​the heat exchange module decreases, the width of the overall device becomes narrower.

Then, the rotating shaft 9 is rotated to make the second support rod 5 and the first thread groove 10 threadably rotated, shortening the exposed length of the second support rod 5, thereby improving the clamping degree of the two baffles 2.

[0034] A further optimized solution is that the telescopic plate assembly includes a slide plate 11 fixedly connected to one of the bases 1, the slide plate 11 is located between the two bases 1, and a slide groove 12 is opened at one end of the other base 1 close to the slide plate 11, and the slide plate 11 extends into the slide groove 12 and is slidably connected to the slide groove 12.
