Description

TECHNICAL FIELD

[0001] The utility model relates to a ventilation floor technical field, concretely relates to a mechanical gear type ventilation floor with high pressure AC small fan. BACKGROUND

[0002] IDC data center, informationization computer room and other special places need to do anti-static treatment, so the floor is all laid with anti-static floor, and the ordinary ventilation floor is arranged at the air inlet of the server cabinet needing cooling or other equipment needing cooling, and the 20-40CM overhead treatment is carried out under the floor.

[0003] And these places basically use computer room special air conditioner to carry out cooling, so the overhead space under the anti-static floor becomes the air supply space of the air conditioner, and the air is supplied to the equipment needing cooling through the ordinary ventilation floor, and this method leads to the fact that the ventilation floor closest to the air conditioner has larger air output, and the ventilation floor far away has smaller air output, so that the equipment at the position cannot obtain the required cold quantity to carry out cooling, first, the temperature gradient in the area is generated, and the requirement of constant temperature and humidity environment is deviated, second, the area temperature gradually rises, and the long-term operation of the equipment is not conducive, therefore, the ventilation floor is used to assist ventilation and cooling in the prior art.

[0004] In the current ventilation floor system, in order to ensure the efficiency of the ventilation effect, a fan with larger power is usually used. However, these high-power fans will generate greater vibration during operation, which not only causes potential damage to the equipment itself, but also affects the surrounding environment. Specifically, these vibrations will cause a large amount of noise to be generated, thereby causing interference to people's work and living environment. Therefore, we propose a mechanical gear type ventilation floor with high pressure AC small fan. CONTENT OF THE UTILITY MODEL

[0005] The utility model aims at: for solving in the current ventilation floor system, in order to ensure the efficiency of the ventilation effect, a fan with larger power is usually used. However, these high-power fans will generate greater vibration during operation, which not only causes potential damage to the equipment itself, but also affects the surrounding environment. Specifically, these vibrations will cause a large amount of noise to be generated, thereby causing interference to people's work and living environment. The utility model provides a mechanical gear type ventilation floor with high pressure AC small fan.

[0006] The utility model realizes the above-mentioned purpose specifically by adopting the following technical scheme:

[0007] A mechanically adjustable ventilation floor equipped with a high-pressure AC fan includes an overhead support frame. The upper end of the overhead support frame is fixedly connected to the ventilation floor, and the upper side of the ventilation floor is evenly provided with multiple large waist holes. Vibration damping grooves are provided on the inner side of the four corners of the bottom of the overhead support frame, and elastic vibration damping seats are installed on the foot pads of the overhead support frame corresponding to the center of the vibration damping grooves. X-shaped brackets are fixedly connected to the upper ends of the four elastic vibration damping seats. A central counterweight is fixedly connected to the center of the upper side of the X-shaped bracket, and AC fans are fixedly connected to the center of the upper ends of the four side supports of the X-shaped bracket.

[0008] Furthermore, the inner cavity of the central counterweight barrel is hollow, and the inner cavity of the central counterweight barrel is filled with multiple energy-dissipating steel balls and damping mineral oil.

[0009] Furthermore, a hollow rubber support column is fixedly connected to the bottom center of the X-shaped bracket, and a central damping spring is fixedly installed inside the hollow rubber support column.

[0010] Furthermore, a connecting rod is movably inserted into the upper end of the elastic damping seat, and a compression spring is fixedly connected between the bottom of the connecting rod and the bottom of the inner cavity of the elastic damping seat.

[0011] Furthermore, the outer ends of the four side supports of the X-shaped bracket are all fixedly connected with connecting hinge seats, and the outer side of the connecting hinge seats is hinged to the upper end of the connecting rod.

[0012] Furthermore, an annular baffle is fixedly connected to the inner wall of the upper frame of the overhead support frame near the bottom, and a reinforcing grid plate is inserted at the upper end of the overhead support frame. The bottom of the outer frame of the reinforcing grid plate abuts against the annular baffle plate, and multiple guide grids are symmetrically distributed on both sides of the inner side of the reinforcing grid plate.

[0013] Furthermore, the AC small fan is an AC high-pressure axial flow fan with a diameter of 20 centimeters, and the AC axial flow fan is electrically connected to a mechanical speed controller.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model utilizes an overhead support frame that, in conjunction with a ventilated floor, forms an overhead ventilation layer beneath the server rack. Multiple small AC fans blow air upwards to assist ventilation. The large perforations on the ventilated floor provide natural ventilation of approximately 90%, and the concentrated load can reach one ton, aiding in server rack heat dissipation. Elastic vibration damping seats and a central counterweight buffer buffer the mechanical vibrations generated by the multiple small AC fans through the expansion and contraction of the four elastic damping seats. The central counterweight increases the weight at the center of the X-shaped bracket, reducing the impact of AC fan vibrations on the X-shaped bracket, decreasing the vibration amplitude and frequency, and significantly reducing vibration noise during AC fan operation, thus improving the quietness of the server room environment.

[0016] 2. This utility model uses multiple energy-dissipating steel balls and damping mineral oil. When the central counterweight barrel receives the vibration of the X-shaped bracket, the multiple energy-dissipating steel balls can shake and collide with each other to dissipate energy, thereby improving the vibration reduction and energy dissipation effect of the central counterweight barrel. The damping mineral oil improves the movement damping of the energy-dissipating steel balls through its viscosity, thereby improving the energy dissipation effect of the energy-dissipating steel balls and reducing the collision noise of the energy-dissipating steel balls.

[0017] 3. This utility model improves the vibration reduction effect at the center of the X-shaped bracket by setting a hollow rubber support column and a central vibration damping spring, with the central vibration damping spring in contact with the ground. Attached Figure Description
