Description

Technical Field

[0001] This utility model relates to the field of sound-absorbing cotton technology, specifically to a porous structure sound-absorbing cotton with radiative cooling function. Background Technology

[0002] Sound-absorbing cotton absorbs sound waves from a sound source through its porous structure and special sound-absorbing inclined surface structure, thus achieving sound insulation and noise reduction. However, due to its internal cavity structure, sound-absorbing cotton has poor heat dissipation. Therefore, when using sound-absorbing cotton for noise reduction, it can significantly affect the heat dissipation of equipment, causing some equipment to overheat during operation. A new type of environmentally friendly thermal insulation material exists. Through its special molecular structure, the material surface can utilize atmospheric wavelength windows to scatter heat outward in the form of thermal radiation. Furthermore, the material can significantly reflect visible light wavelengths, thus achieving thermal insulation. Using this material technology on sound-absorbing cotton can passively increase its unidirectional heat dissipation capacity, enabling the sound-absorbing cotton to assist in the cooling and heat dissipation of equipment. Specific structural development is needed for this. Summary of the Invention

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a porous sound-absorbing cotton with radiative cooling function. By setting heat-conducting structures and radiative heat dissipation structures on both sides of the sound-absorbing cotton body, it can achieve unidirectional heat dissipation of the sound-absorbing cotton body, enabling the equipment to be cooled and cooled when using this sound-absorbing cotton. Furthermore, this sound-absorbing cotton has improved the installation structure and optimized its structure to adapt to various installation environments.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: It includes the sound insulation cotton body, and it also includes: The heat-absorbing plate consists of several heat-absorbing plates that cover one side wall of the sound insulation cotton body. The heat-absorbing plates are arranged in two sets, upper and lower, in an interlocking manner. The radiation plate consists of several pieces and is installed on the other side wall of the sound insulation cotton body. The radiation plates are arranged in two sets, upper and lower, and are interlocked in an alternating manner. The cutting seam is set on the sound insulation cotton body. The cutting seam is a perforated structure with a dot matrix structure. One side of the opening of the cutting seam is set between adjacent heat absorption plates, and the other side of the opening of the cutting seam is set between adjacent radiation plates.

[0005] Preferably, the two ends of a cutting seam are respectively connected to the ends of the adjacent cutting seams on both sides, and the two adjacent cutting seams are arranged at a certain angle.

[0006] Preferably, the sound insulation cotton body is embedded with an array of heat-conducting sheets. A group of heat-conducting sheets consists of several sheets arranged in an array between the heat-absorbing plates and the radiation plates on both sides. One end of the heat-conducting sheet is fixedly mounted on the heat-absorbing plate, and the other end of the heat-conducting sheet is fixedly mounted on the radiation plate. The heat-conducting sheet has a multi-segment bent structure.

[0007] Preferably, the sound insulation cotton body is covered with edge sealing strips on both sides, and the heat absorption plate and radiation plate are sandwiched between the edge sealing strips on the upper and lower sides.

[0008] Preferably, an array of rivets is threaded through the edge sealing strip, and the array consists of two rivets positioned between one side of two adjacent cut seams, with the rivets movably threaded through the side of the sound insulation cotton body.

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] like Figure 1-6 As shown, the specific implementation adopts the following technical solution: This specific embodiment includes a sound-insulating cotton body 1, a heat-absorbing plate 2, and a radiation plate 3. The sound-insulating cotton body 1 is strip-shaped. The heat-absorbing plate 2 and the radiation plate 3 are respectively disposed on both sides of the sound-insulating cotton body 1. A heat-conducting sheet 5 is disposed between the heat-absorbing plate 2 and the radiation plate 3. The two ends of the heat-conducting sheet 5 are respectively fixedly disposed on the heat-absorbing plate 2 and the radiation plate 3 on both sides, and the heat-conducting sheet 5 is embedded between the sound-insulating cotton body 1. The heat-conducting sheet 5 has a bent wavy structure. There are two sets of heat-absorbing plates 2 arranged in opposite directions. The heat-absorbing plates 2 are triangular in structure, and the upper and lower sets of heat-absorbing plates 2 are staggered and interlocked. The radiation plate 3 has the same shape as the heat-absorbing plates 2 and is also triangular. The upper and lower sets of radiation plates 3 are staggered and interlocked. The sound insulation cotton body 1 is provided with a cutting slit 4, which is a perforated structure with a dot matrix structure. The rear end opening of the cutting slit 4 is located between adjacent heat absorption plates 2, and the front end opening of the cutting slit 4 is located between adjacent radiation plates 3. The cutting slit 4 is a V-shaped structure with the ends connected. The upper and lower sides of the sound insulation cotton body 1 are covered with sealing cotton strips 6. Rivets 7 are inserted through the sealing cotton strips 6. Two rivets 7 are set in a group between the diverging ends of two adjacent cutting slits 4. That is, two rivets 7 in a group are set on one side of the bottom edge of the above-mentioned triangular heat absorption plate 2 or radiation plate 3. A fixing sleeve 8 is inserted and fixed on the sound insulation cotton body 1, and the rivets 7 are inserted inside the fixing sleeve 8.

[0019] When using this sound insulation cotton, the side of the sound insulation cotton body 1 with the heat-absorbing plate 2 attached faces the insulation side of the structure, so that the radiant plate 3 faces the external space. During operation, the heat inside the structure is conducted through the heat-absorbing plate 2, and then the heat on the heat-absorbing plate 2 is transferred to the radiant plate 3 through the heat-conducting sheet 5. The heat is then scattered to the external space through the radiation of the radiant plate 3. When the external space radiates heat to this structure, the radiant plate 3 intercepts the external heat radiation, thereby maintaining the insulation of the structure and scattering the heat of the structure itself to the outside to achieve cooling. The sound insulation cotton body 1 covers the outer wall of the equipment structure to achieve sound insulation and noise reduction. When laying the sound insulation cotton body 1, when there is a bending angle structure, one side of the sound insulation cotton body 1 is cut through the cutting seam 4 to form a toothed structure of the sound insulation cotton body 1. The cut sound insulation cotton body 1 is also a toothed structure. At this time, the cut sound insulation cotton body 1 is bent to achieve its bending at the corner, and the remaining material after cutting is used to fill the gap after bending.

[0020] Compared with the prior art, the beneficial effects of this utility model are: 1. This sound-absorbing cotton absorbs heat on one side and transfers heat to the other side and scatters it into the external space through the heat-absorbing plate 2 and radiation plate 3 attached to its two sides, thereby achieving cooling and sound insulation. 2. Based on its installation structure characteristics, this sound-absorbing cotton has a dot matrix structure cutting seam 4 on the sound insulation cotton body 1. When the sound insulation cotton body 1 is laid and corners need to be bent, the sound insulation cotton body 1 is cut and trimmed through the cutting seam 4 to form a toothed structure, which facilitates bending.

[0021] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
