Description

Technical Field

[0001] This utility model belongs to the field of water pump sound insulation and heat dissipation technology, and specifically relates to a water pump sound insulation and heat dissipation device. Background Technology

[0002] Sound insulation and heat dissipation measures are crucial for water pumps, offering several benefits: 1. Reduced noise pollution: Water pumps generate significant noise during operation, which can disturb workers and negatively impact the quality of life for nearby residents. Sound insulation effectively reduces noise transmission and pollution. 2. Improved work efficiency: A quiet working environment enhances worker focus and productivity. Furthermore, reduced noise pollution helps extend equipment lifespan and lower maintenance costs. 3. Environmental protection: Sound insulation and heat dissipation measures minimize the pump station's impact on the surrounding environment, meeting environmental protection requirements and promoting sustainable development for the company. 4. Enhanced equipment safety: Good heat dissipation design prevents pump motor damage from overheating, ensuring normal equipment operation. Sound insulation also helps reduce wear and tear caused by vibration, improving equipment safety and reliability.

[0003] In existing technologies, pumping stations are equipped with multiple water pumps for convenient water supply, but sound insulation technology has significant drawbacks: traditional single-layer soundproof enclosures have insufficient noise reduction efficiency and are difficult to absorb low- and mid-frequency vibration noise; relying on natural convection heat dissipation through heat dissipation vents has low efficiency, leading to excessive internal temperature rise and accelerating equipment aging; open heat dissipation vents easily introduce dust, contaminating the unit when it is shut down; fixed installation designs are cumbersome to disassemble and assemble, making it difficult to adapt to high-frequency maintenance needs; rigid connections exacerbate vibration transmission and induce secondary noise. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a sound insulation and heat dissipation device for a water pump. Through a double-layer plate structure sound insulation frame, which adopts a honeycomb structure, a phase change material layer, and a cold water pipe circulation, the device effectively blocks the noise transmission path while enhancing the heat dissipation of the equipment.

[0005] The technical solution of this utility model is as follows: a water pump sound insulation and heat dissipation device, including a base plate, a slot provided on the upper part of the base plate, a sound insulation frame being snapped into the slot, a fan and multiple water pump units being provided on the base plate inside the sound insulation frame, the air outlet of the fan facing the side of the water pump units, the sound insulation frame being a double-layer plate structure, a phase change material layer being provided between the double-layer plates, a molding compound being provided on the inner side of the double-layer plates, the molding compound being a hexagonal honeycomb structure, and the cavity of the hexagonal honeycomb structure being filled with porous sound-absorbing cotton.

[0006] The phase change material layer is equipped with a cold water pipe, which is distributed in an "S" shape within the phase change material layer. The two ends of the cold water pipe are respectively connected to an external circulating water pump and a radiator. The cold water pipe is a copper spiral coil with an outer diameter of 8mm, a wall thickness of 1mm, and a pipe spacing of 20mm.

[0007] The slot is equipped with a rubber shock-absorbing pad.

[0008] The phase change material layer contains a paraffin-based composite phase change material, and the phase change point of the paraffin-based composite phase change material is 40±1℃.

[0009] The thickness of the sound insulation frame is 50mm, and the density of the porous sound-absorbing cotton is 80kg / m³.

[0010] The fan is an axial fan with a power of 25W and an air volume of 30CFM. The fan is equipped with an external power cord, which passes through the soundproof frame and is connected to an external power source.

[0011] The soundproof frame has an inspection port on its side, and the inspection port has a magnetic sealing cover with an opening angle of ≥90°.

[0012] The joint between the base plate and the soundproof frame is sealed with polyurethane sealant, with a sealing rating of at least IP54.

[0013] The technical advantages of this utility model are as follows: 1. The soundproof frame of this utility model adopts a honeycomb structure and is equipped with porous sound-absorbing cotton, which can achieve high-frequency noise reduction of ≥30dB. 2. This utility model uses a phase change material layer sandwiched between two layers of plates to form a sealed cavity. Cold water pipes are evenly distributed inside, and a forced-air cooling fan is installed inside the soundproof frame. The phase change material absorbs heat from the motor and changes from solid to liquid. The cold water circulation and the fan simultaneously dissipate heat, promoting its change from liquid to solid, forming a dynamic thermal balance, which can achieve rapid heat dissipation of the water pump unit. 3. The soundproof frame and the base plate of this utility model are fully enclosed except for the inspection port. The inspection port is only opened during maintenance, effectively preventing dust from entering the equipment and reducing the risk of internal component contamination and corrosion.

[0037] In actual operation, this utility model is as follows:

[0039] Heat dissipation stage: When the temperature inside the sound insulation frame 2 is ≥40℃, the phase change material in the phase change material layer absorbs heat and liquefies, and at the same time, the fan 3 and the cold water pipe 4 start the cold water circulation; the cold water pipe 4 continuously dissipates heat with 20℃ cooling water, so that the phase change material is restored to solidification within 1 hour, and the equipment temperature is maintained at ≤45℃.

[0040] This invention not only solves the problems of high noise and inconvenient heat dissipation in traditional pumping stations, but also avoids the shortcomings of reduced lifespan due to heat generated by the internal motor. While ensuring noise reduction and heat dissipation performance, it significantly improves the maintainability and environmental adaptability of the equipment, making it suitable for long-term stable operation of high-load pumping stations.
