[0001] The utility model relates to the technical field of data center infrastructure, in particular to a precision air conditioner provided with a shutter device to prevent air flow short circuit. Background Art

[0002] Data center infrastructure refers to the basic equipment used to support and maintain the operation of a data center. This infrastructure includes servers, network equipment, storage systems, power and cooling equipment, etc. Servers are the core of a data center, used to store and process large amounts of data and applications. Network equipment is responsible for communication connections within and outside the data center. Storage systems are used to store data persistently. Power equipment ensures the continuous operation of the data center, while cooling equipment manages the temperature of the equipment to prevent overheating. The effective operation of this infrastructure is critical to the performance, reliability and energy efficiency of the data center.

[0003] At present, in addition to the main precision air conditioner, the precision air conditioners in the computer room are all equipped with backup units. When the main precision air conditioner is operating normally, part of the refrigerated air flow provides cooling for the computer room, and part of it returns to the return air outlet of the main air conditioner through the backup precision air conditioner, making the detected return air temperature lower than the actual return air temperature, which cannot meet the cooling capacity required by the computer room.

[0004] Based on this, we propose a precision air conditioner that prevents airflow short circuit and adds shutter equipment to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the name of the utility model to avoid blurring the purpose of this section, the abstract of the specification and the name of the utility model, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0006] Therefore, the purpose of the utility model is to provide a precision air conditioner with a louver device to prevent airflow short circuit, which can solve the problem of inaccurate return air temperature measurement caused by the participation of the standby air conditioner in the airflow circulation in the precision air conditioning unit of the computer room, thereby affecting the main air conditioner's assessment of the actual cooling demand of the computer room. In order to solve the above technical problems, the utility model provides a precision air conditioner with a louver device to prevent airflow short circuit, and adopts the following technical solution: including precision air conditioning equipment, the precision air conditioning equipment includes an air conditioner, and a louver is installed on the top of the air conditioner;

[0007] The precision air conditioning equipment also includes a sealing connector, which is arranged between the air conditioner and the shutter.

[0008] By adopting the above technical solution, the precision air conditioner proposed in this patent is equipped with a shutter device to prevent airflow short circuit, aiming to solve the problem of airflow short circuit that may occur when the main and standby air conditioners are running at the same time in the precision air conditioning unit in the data center computer room. Specifically, the precision air conditioning equipment includes an air conditioner and a shutter installed on the top, wherein the shutter is connected to the forward and reverse motors through a transmission connector, so that the output end of the forward and reverse motors can be connected to the transmission connector for transmission, and multiple groups of blades can be controlled to open and close according to the usage conditions to adapt to the operating state of the precision air conditioning equipment and the direction of the fan, and the bottom of the fixed frame of the shutter is equipped with a fixing plate around it, which is sealed and connected to the metal chassis of the air conditioner through a circular plate body and a circular rubber strip to ensure that the airflow will not leak out from the connection gap between the air conditioner and the shutter;

[0009] The precision air conditioner designed in this scheme is equipped with shutter equipment to prevent air flow short circuit. The opening and closing control of the multiple sets of blades inside the shutter is related to the direction of the EC fan installed on the precision air conditioning equipment and the pressure difference between the upper and lower ends of the EC fan. When the precision air conditioning equipment is in operation and the direction of the EC fan is forward, the multiple sets of blades inside the shutter are controlled to open, allowing hot air to enter the air conditioner for circulation. On the contrary, when the precision air conditioning equipment is in standby or shutdown state, or the pressure difference at the lower end of the EC fan is greater than the pressure difference at the upper end, and the direction of the EC fan is reverse, the multiple sets of blades inside the shutter are controlled to close to prevent cold air from short-circuiting and flowing back to the return air outlet.

[0010] Optionally, the sealing connector includes a circular plate body, and circular adhesive strips are respectively installed on both sides of the circular plate body.

[0011] By adopting the above technical solution, the sealing connection member in this solution is composed of a circular plate body and a circular rubber strip, which can not only play a guiding and limiting role for the blinds installed on the top of the air conditioner, but also effectively improve the sealing of the connection between the air conditioner and the blinds.

[0012] Optionally, the shutter includes a fixing frame, and fixing plates are installed around the bottom of the fixing frame.

[0013] By adopting the above technical solution, the solution can connect and fix the fixing frame to the top of the air conditioner by means of fixing plates installed around the bottom of the fixing frame.

[0014] Optionally, a transmission connector is installed on one end of one side of the fixed frame, and a forward and reverse motor is arranged on one side of the transmission connector. The output end of the forward and reverse motor is transmission-connected to the transmission connector. A plurality of groups of blades are movably connected inside the fixed frame, and the plurality of groups of blades are transmission-connected to each other, and one group of blades is transmission-connected to the transmission connector.

[0015] By adopting the above technical solution, the solution adds a transmission connector and a forward and reverse motor on one side of the fixed frame, and the forward and reverse motor, the transmission connector, and the blades are all transmission connected, so the blades can be controlled to open and close according to usage.

[0016] Optionally, the air conditioner includes a metal chassis, and a plurality of groups of EC fans are arranged at the bottom of one side of the metal chassis.

[0017] By adopting the above technical solution, this solution uses an EC fan installed at the bottom of one side of the metal chassis to supply low-temperature air for precision air-conditioning equipment.

[0018] Optionally, a return air outlet is provided in the middle of the top of the metal chassis, a circular groove is provided around the metal chassis near the return air outlet, and fixing holes are provided at the four corners of the metal chassis near the circular groove and the four corners of the fixing plate.

[0019] By adopting the above technical solution, the solution uses fixing holes respectively opened at the four corners of the metal chassis and the four corners of the fixing plate to connect and fix the metal chassis and the fixing plate.

[0020] Optionally, the circular groove matches the circular plate body and the circular rubber strip structure, and there is a transition fit between the circular groove and the circular rubber strip.

[0021] By adopting the above technical scheme, this scheme can effectively improve the sealing of the connection between the air conditioner and the blinds through the structural design of the transition fit between the circular groove and the circular rubber strip, and can prevent external dust and other impurities from penetrating through the gap between the two groups, thereby ensuring the stability of the connection between the air conditioner and the blinds.

[0022] Optionally, an adjustment groove is opened through the middle of the circular plate body, and connecting baffles are provided on the inner sides of the two groups of circular rubber strips. The connecting baffles match the adjustment groove structure, and multiple groups of compression springs are connected between the two groups of connecting baffles.

[0023] By adopting the above-mentioned technical solution, this solution can push the circular rubber strips connected to both sides of the circular plate body outward by adding multiple groups of compression springs between the two groups of connecting baffles, so that the circular rubber strips can better fit with the bottom of the circular groove, thereby ensuring the airtightness of the connection between the air conditioner and the blinds.

[0024] In summary, the present invention has at least one of the following beneficial effects:

[0025] 1. The precision air conditioner proposed in this patent is equipped with a shutter device to prevent airflow short circuit, which is intended to solve the problem of airflow short circuit that may occur when the main and standby air conditioners are running at the same time in the precision air conditioning unit in the data center computer room. Specifically, the precision air conditioning equipment includes an air conditioner and a shutter installed on the top, wherein the shutter is connected to the positive and negative motors through a transmission connector, so that the output end of the positive and negative motors can be connected to the transmission connector for transmission, and multiple groups of blades can be controlled to open and close according to the usage conditions to adapt to the operating state of the precision air conditioning equipment and the direction of the fan, and the bottom of the fixed frame of the shutter is equipped with a fixing plate around it, which is sealed and connected to the metal chassis of the air conditioner through a circular plate body and a circular rubber strip to ensure that the airflow will not leak out from the connection gap between the air conditioner and the shutter;

[0026] 2. The precision air conditioner designed in this scheme is equipped with shutter equipment to prevent air flow short circuit. The opening and closing control of multiple sets of blades inside the shutter is related to the direction of the EC fan installed on the precision air conditioner and the pressure difference between the upper and lower ends of the EC fan. When the precision air conditioner is in operation and the direction of the EC fan is forward, the multiple sets of blades inside the shutter are controlled to open, allowing hot air to enter the air conditioner for circulation. On the contrary, when the precision air conditioner is in standby or shutdown state, or the pressure difference at the lower end of the EC fan is greater than the pressure difference at the upper end, and the direction of the EC fan is reverse, the multiple sets of blades inside the shutter are controlled to close to prevent cold air from short-circuiting and flowing back to the return air outlet;

[0027] 3. From the above, it can be seen that the precision air conditioner designed in this scheme prevents air flow short circuit by adding shutter equipment. By accurately controlling the opening and closing of the internal blades of the shutter, it effectively prevents the cold air from directly flowing back to the return air outlet, thereby avoiding the problem of air flow short circuit, avoiding unnecessary cold air circulation, reducing the energy consumption of the air conditioning system, and improving the energy efficiency of the entire data center. By controlling the state of the shutter, the temperature of the computer room can be adjusted more accurately to ensure that the server and other equipment operate at an appropriate temperature, preventing equipment overheating due to improper temperature control, and extending the service life of key equipment such as servers. Through the linkage of motors and sensors, the shutters are automatically controlled, reducing manual intervention and improving the intelligence level of the system.
