Embodiment Construction
[0020] Please refer to figure 1 As shown, it shows the specific structure of the preferred embodiment of the present invention, including a frame 10 , an inner insulation layer 20 , an outer insulation layer 30 , an inner panel 40 and an outer panel 50 .
[0021] Both the inner heat insulating layer 20 and the outer heat insulating layer 30 are connected to the inner frame of the frame 10. The frame is connected and fixed, and a sound insulation space 101 is formed between the inner heat insulation layer 20 and the outer heat insulation layer 30. The inner heat insulation layer 20 and the outer heat insulation layer 30 are arranged in parallel and at intervals. 30 have the same thickness, and the width of the sound insulation space 101 is equal to the thickness of the inner heat insulation layer 20 or the thickness of the outer heat insulation layer 30; 50 is covered on the surface of the outer heat insulation layer 30 and welded with the frame 10, and the thickness of the in...
