[0039] Working principle: When the water tank, water pump, compressor and other equipment in the chiller body 1 are working and generating noise, part of the generated noise will be isolated by the sound insulation board 201, and the other part will be transmitted to the sound insulation groove 203 through the sound insulation member 204, thereby achieving a preliminary noise reduction effect. The noise transmitted to the sound insulation groove 203 will be transmitted to the serrated surface of the sound insulation member 204, and the noise will be gradually eliminated through repeated refraction of the serrated surface of the sound insulation member 204, thereby further improving the noise reduction effect.

[0040] When it is necessary to replace the fixing plate 202, the bolts connecting the cover 102 to the body 101 are disassembled by tools, and the cover 102 is removed from the body 101. Subsequently, the handle on the moving rod 504 is moved upward to move the moving rod 504, so that the sliding block 503 slides upward in the sliding groove 502, and the spring 505 is forced to shrink until the spring 505 shrinks to the maximum limit.

At this time, the movable block 507 is engaged with the movable groove 506 until the guide block 402 is separated from the cooperation with the guide groove 401. At this time, the fixing plate 202 is completed. The fixed plate 202 is disassembled; when the fixed plate 202 needs to be installed, the guide block 402 is brought into contact with the end of the guide groove 401, so that the guide block 402 slides in the opposite direction in the guide groove 401 until the side of the guide block 402 contacts the inner wall of the guide groove 401. At this time, the handle on the movable rod 504 is released, and the spring 505 is no longer stressed and begins to stretch, so that the movable rod 504 moves in the opposite direction, so that the sliding block 503 slides downward in the sliding groove 502, so that the inner wall of the movable groove 506 squeezes the inclined surface of the movable block 507, so that the movable block 507 drives the movable block 507 to slide in the opposite direction in the groove 501 until the end of the movable block 507 contacts the side of the sliding block 503. At this time, the fixed block 508 is engaged with the fixed groove 509, and the spring 505 returns to its original shape, and the installation of the fixed plate 202 is completed.
