Description

Technical Field

[0001] This utility model relates to the field of ventilated floor technology, specifically to an intelligent temperature-controlled ventilated floor equipped with a high-pressure fan. Background Technology

[0002] IDC data centers, information server rooms and other special places require anti-static treatment, so all floors are covered with anti-static flooring, and ordinary ventilation flooring is installed at the air inlets of server racks or other equipment that need to be cooled, with a 20-40cm raised floor underneath.

[0003] These types of spaces typically use dedicated air conditioning units for cooling. The raised space beneath the anti-static floor becomes the air supply space for the air conditioner. Air is then delivered to the equipment requiring cooling via ordinary ventilated flooring. This results in a larger airflow from the ventilated flooring closest to the air conditioner, while the airflow from the ventilated flooring further away is very small. Consequently, the equipment in those locations cannot receive the necessary cooling, creating a temperature gradient within the area, deviating from the requirements of a constant temperature and humidity environment. Furthermore, the area remains uncooled for an extended period, causing the temperature to gradually rise, which is detrimental to the long-term operation of the equipment. Therefore, existing technologies use ventilated flooring to provide auxiliary ventilation and cooling for server racks.

[0004] Existing ventilated floors use axial flow fans to blow air directly from the bottom of the floor. Dust can easily enter through the connecting holes in the floor, and cleaning the axial flow fans under the floor is inconvenient. The airflow blows directly onto the cabinets, which can easily bring in dust. Furthermore, when the temperature of the cabinets near the air conditioning outlet is too low, it is necessary to avoid direct cold air blowing. To address these issues, we propose an intelligent temperature-controlled ventilated floor equipped with a high-pressure fan. Utility Model Content

[0005] The purpose of this invention is to address the problems of existing ventilated floors where axial flow fans blow directly from the bottom, making it easy for dust to enter through the ventilation holes, and the axial flow fans under the floor are difficult to clean. Furthermore, the airflow blowing directly onto the cabinets can easily bring in dust, and it is necessary to avoid direct cold air blowing onto cabinets that are close to the air conditioning outlet when the temperature is too low. This invention provides an intelligent temperature-controlled ventilated floor equipped with a high-pressure fan.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] An intelligent temperature-controlled ventilation floor equipped with a high-pressure fan includes an overhead support frame. The upper end of the overhead support frame is fixedly connected to the ventilation floor, and the ventilation floor has multiple large waist holes arranged in a rectangular array. An axial flow fan is installed at the bottom center of the overhead support frame. A sealing seat is inserted into the center of the top frame of the overhead support frame, and the bottom of the sealing seat is recessed downwards. Multiple ventilation holes are equally spaced at the center of the central recess of the sealing seat, corresponding to the center of the multiple rows of large waist holes. The front and rear sidewalls of the central recess of the sealing seat are provided with elastic sealing mechanisms corresponding to the multiple rows of ventilation holes.

[0008] Furthermore, a limiting stop is fixedly connected to the bottom of the inner wall of the top frame of the overhead support frame, and the bottom edge of the sealing seat abuts against the upper side of the limiting stop.

[0009] Furthermore, the elastic sealing mechanism includes an upper crossbar, which is fixedly connected to the inner wall of the front and rear recesses of the sealing seat corresponding to multiple rows of ventilation holes. Multiple guide slides are installed at the bottom of the multiple upper crossbars. A sealing pressure plate is movably sleeved at the bottom of the guide slide, and a compression spring is sleeved on the outer wall of the guide slide. The upper and lower ends of the compression spring abut against the bottom of the ventilation floor and the top of the sealing pressure plate, respectively.

[0010] Furthermore, a rubber sealing ring is fixedly connected to the upper outer edge of the ventilation hole, and a circular groove is opened at the bottom of the sealing plate corresponding to the ventilation hole.

[0011] Furthermore, the bottom of the guide slide rod passes through the sealing pressure plate and is fixedly connected to a limit block.

[0012] Furthermore, silica particles are placed at the bottom of the central recess of the sealing seat as a desiccant.

[0013] Furthermore, the four supports of the overhead support frame are fixedly connected to a cross mounting frame on the inward side, and the axial flow fan is fixedly installed at the upper center of the cross mounting frame.

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

[0015] 1. This utility model features an overhead support frame that, in conjunction with a ventilated floor, forms an overhead ventilation layer beneath the server rack. An axial flow fan blows air towards the ventilated floor, which then passes through large openings and onto the server rack, aiding in heat dissipation. A sealing seat with multiple ventilation holes at its bottom connects the fan output to the large openings. An elastic sealing mechanism automatically opens when airflow is emitted and adjusts the opening width according to the airflow volume, ensuring effective ventilation while preventing dust and debris from entering. When the server rack temperature stabilizes, the axial flow fan is turned off, and the elastic sealing mechanism automatically seals the ventilation holes, reducing cold air output and ensuring stable server rack temperature.

[0016] 2. This utility model features an upper horizontal bar. The sealing pressure plate at the bottom of the upper horizontal bar can be guided by a guide slide bar, restricting the sealing pressure plate to move only up and down along the guide slide bar. The compression spring can assist the sealing pressure plate in applying downward pressure, preventing the sealing pressure plate from rising under the internal cold air and ensuring the cold air isolation effect.

[0017] 3. This utility model improves the sealing performance of the sealing plate and the ventilation hole by setting a rubber sealing ring and a circular groove. The limiting block can restrict the bottom position of the guide slide rod and prevent the guide slide rod from slipping. Attached Figure Description

[0026] In this embodiment, preferably, the elastic sealing mechanism includes an upper crossbar 8. Multiple upper crossbars 8 are fixedly connected to the inner walls of the front and rear recesses of the sealing seat 7 corresponding to multiple rows of ventilation holes 9.
