Description

Technical Field

[0001] This utility model relates to the field of fan boxes, and in particular to an energy-saving, low-noise fan box. Background Technology

[0002] A fan box is a type of ventilation equipment, primarily composed of a fan and a casing. It draws air into the box, pressurizes it with the fan, and then forces it out, thus creating airflow. It functions as an air supply unit, exhaust unit, recirculatory unit, and dust collector, and is widely used in ventilation and air handling systems in buildings, industrial workshops, and residential buildings.

[0003] However, most fan boxes inevitably generate considerable noise due to the airflow inside the box and the operation of the fan. This can cause significant disturbance to people inside, especially when used in offices and private residences, reducing the practicality of the device.

[0004] Therefore, those skilled in the art have provided an energy-saving, low-noise fan box to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide an energy-saving, low-noise fan box. The device comprises a color-coated steel sheet, ultra-fine glass wool, and a galvanized ultrasonic micro-perforated plate arranged from the outside in, forming a highly efficient composite sound-absorbing and sound-insulating structure. This structure effectively utilizes the porous characteristics of the interlayer ultra-fine glass wool to absorb broadband sound energy. Simultaneously, the inner galvanized ultrasonic micro-perforated plate precisely dissipates mid-to-low frequency noise through specific acoustic design, while the outer color-coated steel sheet provides a good sound barrier. The three elements work synergistically to reduce the outward radiation of aerodynamic and mechanical noise during fan operation, resulting in a good overall noise reduction effect. This achieves the environmental goal of low-noise operation and improves the practicality of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An energy-saving, low-noise fan box includes a base, a frame, an air outlet, an air outlet flange, a fan body, an air inlet, and an air inlet flange. A noise reduction mechanism is provided on one side of the outer wall of the frame. The noise reduction mechanism includes a color-coated plate. A galvanized ultrasonic micro-perforated plate is fixedly connected to one end face of the color-coated plate. Ultrafine glass wool is provided on one end face of the galvanized ultrasonic micro-perforated plate and the color-coated plate. Through the above technical solution, the device, consisting of a color-coated plate, ultra-fine glass wool, and a galvanized ultrasonic micro-perforated plate arranged from the outside to the inside, forms a highly efficient composite sound absorption and insulation structure. This structure can effectively utilize the porous characteristics of the interlayer ultra-fine glass wool to absorb broadband sound energy. At the same time, the inner galvanized ultrasonic micro-perforated plate precisely consumes mid-to-low frequency noise through specific acoustic design, while the outer color-coated plate provides a good sound barrier. The three work together to reduce the aerodynamic and mechanical noise radiated outward during the operation of the main fan, resulting in a good overall noise reduction effect. This achieves the environmental protection goal of low-noise operation and improves the practicality of the device.

[0007] Furthermore, a frame is provided on the upper surface of the base, and the frame can be assembled with the noise reduction mechanism, and the base can also be assembled with the noise reduction mechanism; Through the above technical solution, the modular structure design realizes the flexible combination of the base, frame and noise reduction mechanism, which significantly improves the modularity of the product, facilitates transportation, on-site installation and subsequent maintenance, and can effectively reduce structural noise caused by vibration transmission and enhance overall stability.

[0008] Furthermore, an air outlet is provided at the upper center of one side end face of the noise reduction mechanism, and an air outlet flange is threadedly connected to the upper center of one side end face of the noise reduction mechanism. An air inlet is provided at the center of the other side end face of the noise reduction mechanism, and an air inlet flange is threadedly connected to the center of the other side end face of the noise reduction mechanism. Through the above technical solution, the design centrally arranges the air outlet and air outlet flange, as well as the air inlet and air inlet flange on both sides of the noise reduction mechanism, and achieves quick connection through threads, ensuring the airtightness of the air duct, effectively preventing air leakage and noise leakage, while improving the convenience of on-site installation and connection reliability.

[0009] Furthermore, the color-coated plate is the outer layer of the noise reduction mechanism, the galvanized ultrasonic micro-perforated plate is the inner layer, and the ultra-fine glass wool is filled in the interlayer formed between the two. Through the above technical solution, the composite layered structure, through the synergistic effect of color-coated plate, ultra-fine glass wool and galvanized ultrasonic micro-perforated plate, jointly constitutes a high-efficiency broadband sound-absorbing and sound-insulating body, which improves the overall sound absorption and insulation performance of the noise reduction mechanism, and can effectively weaken noise of different frequencies, thereby achieving an overall noise reduction effect.

[0010] This utility model has the following beneficial effects: 1. This utility model proposes an energy-saving, low-noise fan box. The device consists of a color-coated plate, ultra-fine glass wool, and a galvanized ultrasonic micro-perforated plate arranged from the outside to the inside, forming a high-efficiency composite sound absorption and insulation structure.

At the same time, the inner galvanized ultrasonic micro-perforated plate accurately consumes mid-to-low frequency noise through specific acoustic design, while the outer color-coated plate provides a good sound barrier. The three work together to reduce the aerodynamic and mechanical noise radiated outward during the operation of the fan body. The overall noise reduction effect is good, achieving the environmental protection goal of low-noise operation and improving the practicality of the device. Attached Figure Description
