Description

Technical Field

[0001] This utility model relates to the field of server rack technology, specifically a fully enclosed liquid-cooled back-door noise reduction rack. Background Technology

[0002] Server racks are standardized metal frame structures used to house, protect, and manage servers and related network equipment. They are an indispensable infrastructure in data centers, server rooms, and other similar settings.

[0003] Currently, common single-rack cooling systems consume a lot of energy, and the heat exchange between the rack and the outside air results in a waste of cooling capacity, exacerbating the loss of cooling capacity. Especially in high temperature or high humidity environments, the cooling system needs to consume additional energy to maintain temperature control standards, further increasing energy consumption and resulting in poor energy-saving effects. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fully enclosed liquid-cooled back-door noise reduction cabinet, which has the advantages of reducing energy consumption and noise, and solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully enclosed liquid-cooled back-door noise reduction cabinet, including a cabinet body, wherein a rear door airflow guide assembly and a side panel airflow guide assembly are provided inside the cabinet body;

[0006] The rear door airflow guide assembly includes multiple turbine fans installed inside the cabinet. A copper tube aluminum fin heat exchanger is installed inside the cabinet and is connected to external equipment. The multiple turbine fans are located behind the copper tube aluminum fin heat exchanger. Two airflow guide frames are installed on the front of the copper tube aluminum fin heat exchanger and there is a gap between the two airflow guide frames and the cabinet.

[0007] The side panel flow guiding assembly includes two flow guiding plates. Each of the two flow guiding plates has a bracket fixedly connected to its opposite side. Both brackets are fixedly connected to the inner wall of the cabinet. Each of the two flow guiding plates is engaged with a flow guiding frame that is close to it.

[0008] Furthermore, a back door is installed on the back of the cabinet, and a front door is installed on the front of the cabinet. Both the front door and the back door are connected to the cabinet by sealing rings.

[0009] With the above solution, both the front door and the back door are connected to the cabinet body by sealing rings, which enhances the airtightness of the cabinet, further prevents cold air leakage and the entry of outside air, helps maintain a low temperature environment inside the cabinet, and also enhances the noise reduction effect.

[0010] Furthermore, the cabinet is made entirely of metal.

[0011] The above solution uses an all-metal cabinet. Metal has good thermal conductivity and mechanical strength, which helps to improve the heat dissipation performance and structural stability of the cabinet. At the same time, metal also helps to shield some external noise, further improving the noise reduction effect.

[0012] Furthermore, there is a gap between the front of the two deflectors and the front door.

[0013] With the above design, there is a gap between the front of the two deflectors and the front door, allowing cold air to pass smoothly during circulation without being obstructed by the deflectors and the front door, thus ensuring heat dissipation efficiency.

[0014] Furthermore, the number of the turbine fans is no less than five.

[0015] The above solution provides stronger airflow, ensuring that cool air circulates quickly within the cabinet, carrying away the heat generated by the host and improving heat dissipation efficiency. It also provides better conditions for the active noise cancellation mechanism where sound waves cancel each other out.

[0016] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0017] This fully enclosed liquid-cooled back-door noise reduction cabinet, through the cooperation of the rear door airflow guide component and the side panel airflow guide component, enables the circulation of cold air within the U-shaped airflow channel. During the circulation process, the cold air passes through the main unit inside the cabinet and carries away the heat from the main unit, achieving efficient heat dissipation for the main unit inside the cabinet. Subsequently, heat is exchanged through a copper tube aluminum fin heat exchanger. Because the cabinet is in a sealed state, the cold air will not escape from the cabinet, and outside air will not enter the cabinet, ensuring that the cabinet maintains a low temperature for a long time, achieving isolation between the cabinet and the outside air, thereby maintaining a suitable low temperature for the main unit to operate inside the cabinet, while improving energy efficiency.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Please see Figures 1-4 The fully enclosed liquid-cooled back-door noise reduction cabinet in this embodiment includes a cabinet body 1, and a rear door airflow guide assembly 2 and a side panel airflow guide assembly 3 are provided inside the cabinet body 1.

[0030] The rear door airflow guide assembly 2 includes multiple turbine fans 201 installed inside the cabinet 1. A copper tube aluminum fin heat exchanger 202 is installed inside the cabinet 1. The copper tube aluminum fin heat exchanger 202 is connected to external equipment. The multiple turbine fans 201 are all located behind the copper tube aluminum fin heat exchanger 202. Two airflow guide frames 203 are installed on the front of the copper tube aluminum fin heat exchanger 202. There is a gap between the two airflow guide frames 203 and the cabinet 1.

[0031] The side panel airflow guide assembly 3 includes two airflow guide plates 301. Each of the two airflow guide plates 301 has a bracket 302 fixedly connected to its opposite side. Both brackets 302 are fixedly connected to the inner wall of the cabinet 1. Each of the two airflow guide plates 301 is engaged with its adjacent airflow guide frame 203. The combination of the airflow guide frame 203, the airflow guide plate 301, and the copper tube aluminum fin heat exchanger 202 enables a U-shaped airflow channel to be formed inside the cabinet 1.

[0032] By cooperating with the rear door airflow guide component 2 and the side panel airflow guide component 3, cold air can circulate inside the U-shaped airflow channel. During the circulation process, the cold air can pass through the host inside the cabinet 1 and carry away the heat from the host, achieving efficient heat dissipation for the host inside the cabinet 1. Subsequently, heat is exchanged through the copper tube aluminum fin heat exchanger 202. Since the cabinet 1 is in a sealed state, the cold air will not be emitted out of the cabinet, and the outside air will not enter the cabinet, ensuring that the cabinet maintains a low temperature for a long time, achieving isolation between the cabinet 1 and the outside air, thereby maintaining a suitable low temperature for the host to operate inside the cabinet 1, while improving energy efficiency. The cabinet 1 also has a noise reduction function. Through the sealing of the entire cabinet, the internal noise is reduced from being released to the outside, playing a passive noise reduction role. Since the back door 4 has a turbine fan 201, the turbine fan 201 will also generate noise when it runs. By adjusting, the operating noise of the turbine fan 201 and the noise of the server inside the cabinet 1 are actively adjusted. The fan noise matches the noise of the server inside the cabinet 1 to cancel each other out, achieving active noise reduction.

[0033] The back of cabinet 1 is equipped with a back door 4, and the front of cabinet 1 is equipped with a front door 5. Both the front door 5 and the back door are connected to cabinet 1 by sealing rings. The sealing of cabinet 1 is enhanced, further preventing cold air leakage and the entry of outside air, which helps to maintain a low temperature environment inside the cabinet and also enhances the noise reduction effect. Cabinet 1 is made of all-metal material. Metal has good thermal conductivity and mechanical strength, which helps to improve the heat dissipation performance and structural stability of the cabinet. At the same time, metal also helps to shield some external noise, further improving the noise reduction effect.

[0034] There is a gap between the front of the two air deflectors 301 and the front door 5. This gap allows cold air to pass smoothly during circulation and does not affect airflow due to obstruction between the air deflectors 301 and the front door 5, thus ensuring heat dissipation efficiency. The number of turbine fans 201 is no less than five. The setting of multiple turbine fans 201 can provide stronger airflow, ensuring that cold air circulates quickly in the cabinet 1, carrying away the heat generated by the host, improving heat dissipation efficiency, and also providing better conditions for the active noise cancellation mechanism of sound wave mutual cancellation.

[0035] It should be noted that the copper tube aluminum fin heat exchanger 202 is a high-efficiency heat exchange device that combines the advantages of copper tubes and aluminum fins to achieve heat transfer between two fluids at different temperatures. When the cold fluid flows in the copper tube, the aluminum fins are also at a low temperature. Heat from the surrounding air can be transferred to the cold fluid in the copper tube through the aluminum fins, thereby achieving a cooling effect.

[0036] The working principle of the above embodiment is as follows: First, when the cabinet 1 is working, multiple turbine fans 201 start and generate airflow, which can carry away the heat of the host inside the cabinet 1 as it passes through the U-shaped airflow channel and is transported to the copper tube aluminum fin heat exchanger 202, so that the copper tube aluminum fin heat exchanger 202 exchanges heat with the outside and dissipates the heat. During the circulation of cold air inside the cabinet 1, since the cabinet 1 is in a sealed state, the cold air will not be dissipated outside the cabinet and the outside air will not enter the cabinet, ensuring that the cabinet is kept at a low temperature for a long time, realizing the isolation between the cabinet 1 and the outside air, thereby maintaining a suitable low temperature for the host to work inside the cabinet 1, and improving the energy-saving effect. During the operation of the host inside the cabinet 1, since the cabinet 1 is in a closed state, the internal noise is reduced and released to the outside, playing a passive noise reduction role. By adjusting the power of the turbine fans 201, the noise of the turbine fans 201 cancels out the noise of the host inside the cabinet 1, thus realizing active noise reduction of the host operating noise.
