Detailed Implementation

[0018] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0019] like Figure 1-4This utility model discloses an energy-saving heat exchange device for a computer room. The device includes an exhaust fan 1, an exhaust fan 2, a heat exchanger 13, and a ventilation assembly 5. The exhaust fan 1, exhaust fan 2, and heat exchanger 13 are all installed on the walls of the computer room. The heat exchanger uses existing tubular or plate heat exchangers. Electrical equipment, such as server racks, is installed in the computer room. The exhaust port of the exhaust fan 1 is connected to an exhaust pipe 4, which is located at the bottom of the computer room. The exhaust port of the exhaust fan 1 is connected to the inlet of the heat exchanger 13 via a pipe. The exhaust port of the exhaust fan 2 is connected to the outlet of the heat exchanger 13 via a pipe. The air vent is connected to an air supply duct 3, which is located on the rear wall of the computer room. The air intake duct 4 includes multiple air intake branch pipes connected to one end of the air intake duct 4, and each air intake branch pipe has multiple air intake holes. The air supply duct 3 includes an air supply branch pipe connected to one end of the air supply duct 3, and each air supply branch pipe has multiple air supply holes. The ventilation and air exchange assembly 5 includes an exhaust fan 501 and a shielding component 502. Ventilation holes 8 are provided on both the left and right side walls of the computer room. The exhaust fan 501 is installed outside the ventilation hole 8, and a shielding component 502 is installed outside the exhaust fan 501. A first temperature and humidity sensor 6 is installed inside the computer room, and a second temperature and humidity sensor 7 is installed outside the computer room. When the outdoor air temperature and humidity are low, outdoor air is introduced into the computer room through the exhaust fan to ventilate the computer room, thereby achieving the purpose of cooling, reducing the energy consumption of the computer room, and achieving the purpose of energy saving. When the outdoor air temperature and humidity are high, which is not conducive to cooling the computer room, the exhaust fans are turned off, and the ventilation openings are blocked with shielding to reduce the entry of hot and humid outdoor air into the computer room and its impact on the equipment. At this time, the computer room is cooled by a heat exchanger. Multiple branch pipes are connected to the intake and exhaust ducts to facilitate rapid cooling. The intake duct includes multiple intake branch pipes connected to one end of the intake duct, each with multiple intake holes to quickly draw hot air from the computer room into the heat exchanger for cooling. The exhaust duct includes multiple exhaust branch pipes connected to one end of the exhaust duct, each with multiple exhaust holes. The cooled air is then delivered into the computer room through the exhaust branch pipes. Multiple exhaust branch pipes facilitate the rapid distribution of cooled air to various locations within the computer room, achieving rapid cooling.

[0020] The shielding component 502 includes a first filter plate 503, a second filter plate 504, and an electric telescopic rod 505. The first filter plate 503 is bolted to the outside of the ventilation fan 501 for easy disassembly, maintenance, and replacement. The first filter plate 503 has sliding grooves 506 at both its upper and lower ends. The second filter plate 504 is slidably installed within the sliding grooves 506. The first filter plate 503 has first filter holes 507, on which high-efficiency filter cotton is installed. The second filter plate 504 has second filter holes 508, on which pre-filter cotton is installed. A support plate 509 is installed on the exterior of the computer room wall. An electric telescopic rod 505 is horizontally mounted on the support plate 509. One side of the second filter plate 504 is bolted to the telescopic end of the electric telescopic rod 505 for easy disassembly, maintenance, and replacement. The second filter plate slides against the outside of the first filter plate. During ventilation, the electric telescopic rod moves the position of the second filter plate, aligning the first and second filter holes. Air enters the computer room through both the second and first filter holes. The primary filter cotton on the second filter hole provides initial filtration, removing larger dust particles or other impurities. The high-efficiency filter cotton on the first filter hole further filters the air, removing smaller dust particles, keeping the air entering the computer room clean and reducing dust entry. When the ventilation fan is turned off, the electric telescopic rod moves the second filter plate to completely cover the first filter hole, further reducing air intake.

[0021] A wind speed sensor 9 is installed on the ventilation hole 8 and inside the ventilation fan 501. The wind speed sensor can monitor the air intake speed of the ventilation hole, and whether the ventilation fan is working properly or whether the first filter hole or the second filter hole is ventilating properly. When the wind speed sensor detects an abnormal air intake speed of the ventilation hole, it will sound an alarm light to remind the staff that there is an abnormality in the ventilation fan or filter plate, so that the staff can check and repair it in time to ensure normal ventilation in the computer room.

[0022] The energy-saving heat exchange device for the computer room also includes an alarm light 10, which is installed inside the computer room. There are two alarm lights, one for each of the two wind speed sensors. When a wind speed sensor detects an abnormality, the corresponding alarm light will sound, making it easier for staff to check the corresponding ventilation fan or filter plate.

[0023] The energy-saving heat exchange device for the computer room also includes a controller 11 and a display screen 12 installed inside the computer room. The exhaust fan 1, supply fan 2, heat exchanger 13, ventilation fan 501, first temperature and humidity sensor 6, second temperature and humidity sensor 7, electric telescopic rod 505, wind speed sensor 9, alarm light 10, and display screen 12 are all electrically connected to the controller 11. The device is powered by mains electricity to ensure normal operation. The exhaust fan 1, supply fan 2, heat exchanger 13, ventilation fan 501, first temperature and humidity sensor 6, second temperature and humidity sensor 7, electric telescopic rod 505, wind speed sensor 9, alarm light 10, display screen 12, and controller 11 involved in this device are all existing technologies. Their circuit connection structures and control principles are common knowledge in the field and will not be described in detail here.

[0024] Work process:

[0025] The working principle of this utility model is as follows: The first temperature and humidity sensor 6 can monitor the air temperature and humidity inside the computer room, and the second temperature and humidity sensor 7 can monitor the air temperature and humidity outside the computer room. When the outdoor air temperature and humidity are low and meet the ventilation requirements, outdoor air is introduced into the computer room through the ventilation fan 501 to ventilate the computer room. The position of the second filter plate 504 is moved by the electric telescopic rod 505 so that the first filter hole 507 and the second filter hole 508 overlap. Air enters the computer room through the second filter hole 508 and the first filter hole 507. The primary filter cotton on the second filter hole 508 can perform preliminary filtration of the air, removing larger dust or other impurities. The high-efficiency filter cotton on the first filter hole 507 filters the air again, further removing smaller dust, keeping the air entering the computer room clean and reducing dust entering the computer room. When the outdoor air temperature and humidity are high, which is not conducive to cooling the computer room, the ventilation fan 501 is turned off, and the ventilation hole 8 is blocked by the shield 502 to reduce the entry of hot and humid outdoor air into the computer room and its impact on the equipment. Specifically, the second filter plate 504 is moved by the electric telescopic rod 505 to completely block the first filter hole 507, further reducing air intake. At this time, the heat exchanger 13 in the computer room cools the room. Multiple branch pipes are connected to the air intake pipe 4 and the air supply pipe 3 to facilitate rapid cooling of the computer room. This allows for the rapid delivery of cooled air to various locations within the computer room, achieving the goal of rapid cooling.

[0026] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
