[0030] The specific implementation process of the utility model is as follows: when in use, first push the insulation sheet 1 2 and the insulation sheet 2 3 to contact the left and right ends of the plate heat exchanger body 1, then push the insulation sheet 3 4 to contact the front and rear ends of the plate heat exchanger body 1, and make the Velcro hook surface 1 7 contact the Velcro fur surface 1 6, and fix the insulation sheet 1 2, the insulation sheet 2 3, and the insulation sheet 3 4 to each other, and then push the insulation sheet 4 5 to contact the upper end of the plate heat exchanger body 1, so that the Velcro hook surface 2 9 is in contact with the Velcro fur surface 2 8, and fix the insulation sheet 4 5, the insulation sheet 1 2, the insulation sheet 2 3, and the insulation sheet 3 4 to each other, so as to ensure the stable installation of the insulation sleeve, and then perform insulation treatment on the plate heat exchanger body 1;

Under the action of force, the damping plate 107 moves along the surface of the telescopic plate 102. When the damping plate 107 slides into the next damping groove 105, the spring 2 108 restores the deformation to push the damping plate 107 to insert into the damping groove 105. This cycle is repeated to wear out the excess deformation stress generated by the spring 2 108, thereby avoiding the problem of excess shaking of the spring 2 108.
