Description

Technical Field

[0001] This application relates to the technical field of fan box noise reduction equipment, and specifically discloses an environmentally friendly and energy-saving soundproof cover. Background Technology

[0002] Roof ventilators are essential equipment for ventilation in industrial plants, commercial buildings, and other similar locations. However, during operation, the rotation of the impeller and the turbulent airflow generate significant aerodynamic noise, causing noise pollution to the surrounding environment. To address this issue, the most common technical solution in the industry is to install soundproof covers on the ventilators.

[0003] Existing wind turbine soundproof enclosures typically employ a metal frame and multi-layer composite sound insulation panel structure, such as a composite of steel plates, damping layers, and porous sound-absorbing materials. This structure effectively controls the noise generated during wind turbine operation within the enclosure through sound wave absorption, reflection, and blocking, significantly reducing noise radiation to the external environment and achieving good noise reduction and sound insulation effects.

[0004] However, the sealed or semi-sealed structure of soundproof enclosures, designed for sound insulation, severely hinders heat dissipation from the fan motor and the interior of the casing. The drive motor in the fan generates a significant amount of heat during prolonged operation. Within the enclosed environment of existing soundproof enclosures, this heat cannot be quickly and effectively exchanged with the outside air, causing the internal temperature of the casing to accumulate and continuously rise. Excessively high operating temperatures not only reduce motor efficiency and shorten its lifespan but may also lead to malfunctions or safety hazards due to overheating.

[0005] To alleviate heat dissipation problems, users are often forced to take additional cooling measures, such as increasing the power of the fan itself to force exhaust, or adding extra ventilation openings and auxiliary cooling fans to the soundproof enclosure. While these remedial measures improve heat dissipation to some extent, they directly lead to an additional increase in the overall energy consumption of the equipment. This contradicts the current advocacy of energy conservation, emission reduction, and green environmental protection for sustainable development. In view of this, this utility model provides an environmentally friendly and energy-saving soundproof enclosure to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to provide an environmentally friendly and energy-saving soundproof cover that can improve the heat dissipation performance of the fan casing while ensuring excellent sound insulation and noise reduction, so as to solve the problem of poor heat dissipation performance of traditional soundproof covers.

[0007] To achieve the above objectives, the basic solution of this utility model provides an environmentally friendly and energy-saving soundproof cover, which is installed on the outer wall of the roof fan box and includes several soundproof cover bodies that are detachably connected to each other and a phase change heat pipe located inside the soundproof cover body. The phase change heat pipe includes a heat absorption pipe located on the side of the soundproof enclosure near the roof fan box, a heat dissipation pipe located on the other side of the soundproof enclosure, and a flow guide pipe located between the heat absorption pipe and the heat dissipation pipe. The phase change heat pipe stores a phase change medium that absorbs heat and evaporates in the heat absorption pipe and dissipates heat and condenses in the heat dissipation pipe.

[0008] The principle and effect of this basic scheme are as follows: Compared with existing technologies, this invention incorporates a phase change heat pipe within the soundproof enclosure. This heat-absorbing pipe absorbs heat from the side of the fan casing near the roof and transfers it to the other side of the enclosure via a phase change medium, thereby dissipating the heat to the external environment. This effectively improves the heat dissipation performance of the fan casing, ensuring excellent sound insulation and noise reduction while enhancing the heat dissipation of the fan casing. This achieves a balance between noise reduction performance, heat dissipation efficiency, and energy consumption, solving the problem of poor heat dissipation performance in traditional soundproof enclosures.

[0009] Furthermore, the guide pipe is vertically connected between the heat absorption pipe and the heat dissipation pipe, or the guide pipe is inclinedly connected between the heat absorption pipe and the heat dissipation pipe, and the side of the guide pipe closer to the heat dissipation pipe is higher than the side of the guide pipe closer to the heat absorption pipe. This is to facilitate adaptation to different environments, such as installing the sound insulation enclosure on the top or side wall of the fan casing.

[0010] Furthermore, the soundproof enclosure comprises, from the inside out, a heat-conducting layer, a protective layer, a sound-absorbing layer, a damping layer, a heat-dissipating layer, and a sound-insulating layer. The heat-conducting and heat-dissipating layers, in conjunction with phase-change heat pipes, facilitate heat transfer. Simultaneously, the protective and sound-insulating layers provide the necessary installation environment, the sound-absorbing layer reduces noise, and the damping layer suppresses resonance. This ensures excellent sound insulation and noise reduction while improving the heat dissipation performance of the fan casing.

[0011] Furthermore, the heat-absorbing pipe is filled within the protective layer and connected to the thermally conductive layer, while the heat-dissipating pipe is filled within the damping layer and connected to the heat-dissipating layer. This facilitates heat transfer through the cooperation of the thermally conductive layer, the heat-dissipating layer, and the phase-change heat pipe.

[0012] Furthermore, a length difference is formed between the soundproof enclosure and the end of the phase change heat pipe, and the end of the phase change heat pipe is detachably connected to a connector that seals or connects the phase change heat pipe. This facilitates the connection of adjacent soundproof enclosures to each other, and simultaneously connects the phase change heat pipes inside adjacent soundproof enclosures to promote the flow of the phase change medium, thereby improving heat dissipation performance.

[0013] Furthermore, the connector includes a plug or connecting pipe detachably connected to the end of the phase change heat pipe, wherein the connecting pipe is a straight pipe or a bend, to facilitate the interconnection and mating of the transverse or longitudinal sound insulation enclosures.

[0014] Furthermore, the inner wall of the phase change heat pipe end is provided with a socket, and the end of the connector is inserted into the socket. This facilitates the connection and disconnection of the connector and the phase change heat pipe.

[0015] Furthermore, the inner wall of the socket is provided with a stepped surface adapted to the connector, and a sealing groove is provided in the stepped surface, with a sealing ring provided in the sealing groove. This is to improve the sealing performance between the connector and the socket. Attached Figure Description

[0016] To more clearly illustrate the technical solutions in the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0017] Figure 1 A side cross-sectional view of an environmentally friendly and energy-saving soundproof enclosure according to an embodiment of this application is shown; Figure 2 This shows a cross-sectional view of another side of an environmentally friendly and energy-saving soundproof enclosure proposed in an embodiment of this application. Detailed Implementation

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] The reference numerals in the accompanying drawings include: thermally conductive layer 1, protective layer 2, sound-absorbing layer 3, damping layer 4, heat dissipation layer 5, sound insulation layer 6, heat absorption pipe 7, heat dissipation pipe 8, flow guiding pipe 9, socket 10, connector 11, and sealing ring 12.

[0020] An environmentally friendly and energy-saving soundproof enclosure is installed on the top or side of a rooftop fan unit, implementing, for example... Figure 1 and Figure 2 As shown: This includes several detachably connected soundproof enclosures and phase-change heat pipes located inside the soundproof enclosures. Each soundproof enclosure comprises, from the inside out: a heat-conducting layer 1, a protective layer 2, a sound-absorbing layer 3, a damping layer 4, a heat dissipation layer 5, and a sound-insulating layer 6. The heat-conducting layer 1 uses a thermally conductive silicone pad; the protective layer 2 uses a perforated plate; the sound-absorbing layer 3 uses centrifugal glass wool; the damping layer 4 is a damping coating; the heat dissipation layer 5 uses a heat spreader; and the sound-insulating layer 6 uses an aluminum plate.

[0021] The phase change heat pipe includes a heat absorption pipe 7 filled in the protective layer 2 and connected to the heat conduction layer 1, a heat dissipation pipe 8 filled in the damping layer 4 and connected to the heat dissipation layer 5, and a flow guide pipe 9 disposed between the heat absorption pipe 7 and the heat dissipation pipe 8. The phase change heat pipe stores demineralized water as a phase change medium, absorbs heat and evaporates in the heat absorption pipe 7, and dissipates heat and condenses in the heat dissipation pipe 8.

[0022] Heat is transferred by using the heat-conducting layer 1, heat dissipation layer 5 and phase change heat pipe. At the same time, the necessary installation environment is provided by the protective layer 2 and sound insulation layer 6. The sound-absorbing layer 3 is used to reduce noise and the damping layer 4 is used to suppress resonance. In order to improve the heat dissipation performance of the fan box while ensuring excellent sound insulation and noise reduction effect.

[0023] When the soundproof enclosure is installed on the top surface of the roof fan unit, the guide pipe 9 is vertically connected between the heat absorption pipe 7 and the heat dissipation pipe 8. When the soundproof enclosure is installed on the side of the roof fan unit, the guide pipe 9 is inclinedly connected between the heat absorption pipe 7 and the heat dissipation pipe 8, and the side of the guide pipe 9 closer to the heat dissipation pipe 8 is higher than the side of the guide pipe 9 closer to the heat absorption pipe 7. In other words, different configurations of the soundproof enclosure are used to adapt to different installation environments on the top or side of the roof fan unit.

[0024] like Figure 2 As shown, a length difference is formed between the sound insulation enclosure and the end of the phase change heat pipe. The end of the phase change heat pipe is detachably connected to a connector 11 that can seal or connect the phase change heat pipe. When the sound insulation enclosure is located at the end of the roof fan box, the connector 11 is used to seal the phase change heat pipe. When two adjacent sound insulation enclosures need to be connected to each other, the connector 11 is used to connect the adjacent phase change heat pipes to achieve the purpose of connecting the adjacent sound insulation enclosures.

[0025] The connector 11 includes a plug or connecting pipe that can be detachably connected to the end of the phase change heat pipe. The connecting pipe can be a straight pipe or a bent pipe. The straight pipe connector 11 facilitates the connection of two horizontally adjacent phase change heat pipes, while the bent pipe facilitates the connection of two vertically adjacent phase change heat pipes.

[0026] The inner wall of the phase change heat pipe end is provided with a socket 10, and the end of the connector 11 extends into the phase change heat pipe and is inserted into the socket 10, so as to facilitate the connection and disconnection of the connector 11 and the phase change heat pipe; at the same time, the inner wall of the socket 10 is provided with a stepped surface that is adapted to the end of the connector 11, and a sealing groove is provided in the stepped surface, and a sealing ring 12 is provided in the sealing groove, so as to improve the sealing performance between the connector 11 and the socket 10.

[0027] By installing phase change heat pipes inside the soundproof enclosure, heat is absorbed from the side of the fan casing near the roof using heat absorption pipe 7, and then transferred to the other side of the soundproof enclosure through the phase change medium. This allows the heat to dissipate to the external environment, effectively improving the heat dissipation performance of the fan casing. This approach ensures excellent sound insulation and noise reduction while enhancing the heat dissipation performance of the fan casing, achieving a balance between noise reduction performance, heat dissipation efficiency, and energy consumption. This solves the problem of poor heat dissipation performance in traditional soundproof enclosures.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
