Description

Technical Field

[0001] This utility model relates to the field of cabinet technology, and in particular to a multi-airflow heat dissipation cabinet. Background Technology

[0002] A server rack is a freestanding or self-supporting enclosure designed for the installation and maintenance of electrical or electronic equipment. It features waterproof, dustproof, and electromagnetic interference protection functions and is widely used in servers, network equipment, and other fields. Because electrical or electronic equipment is installed inside the server rack, and because the rack has a relatively enclosed structure to provide waterproof and dustproof protection, the heat from the electrical or electronic equipment is not easily dissipated. Therefore, air conditioners are often installed outside the server rack for heat dissipation.

[0003] However, the existing server racks lack airflow guidance. The cold air generated by the air conditioner enters the rack in a single stream and cannot be distributed. This means that the cold air can only cool a small area of ​​electrical or electronic equipment and cannot be fully and evenly diffused to other parts of the rack. Therefore, the heat dissipation effect is poor. In order to ensure that the cold air can cover all electrical or electronic equipment, the height of the rack must be limited. If the rack is too tall, the electrical or electronic equipment at the bottom will have difficulty accessing the cold air, so its practicality is also poor and needs further improvement. Utility Model Content

[0004] In view of the current state of the prior art, the technical problem to be solved by this utility model is to provide a multi-airflow cooling cabinet with a guiding function, which can make the cold air fully and evenly diffuse to all positions inside the cabinet to effectively improve the heat dissipation effect, thereby breaking through the height limitation of the cabinet and enhancing its practicality.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a multi-airflow heat dissipation cabinet, including a cabinet body and two positioning frames symmetrically arranged on the left and right sides inside the cabinet body, and air outlet holes and air inlet holes respectively distributed vertically on the left or right inner wall of the cabinet body, characterized in that:

[0006] The positioning frame includes multiple transverse support beams arranged horizontally and distributed in parallel from top to bottom, and two vertical and detachable longitudinal mounting strips fixed between the multiple transverse support beams and distributed front and back respectively. The air outlet and the air inlet are both located between any two adjacent transverse support beams.

[0007] The transverse cross-section of the transverse support beam is shaped like a "Z". The open side of each transverse support beam is fixed to the corresponding inner wall of the cabinet so that a transverse air duct is formed between the interior of each transverse support beam and the corresponding inner wall of the cabinet. The bottom of each transverse support beam has multiple through holes arranged from front to back for fixing the longitudinal mounting strip.

[0008] The inner wall of the cabinet body on the side where the air outlet is located is also provided with a flow guiding component. The flow guiding component includes a flow guiding cover fixed to the inner wall of the cabinet body and sealed around the inner opening of the air outlet, and two first U-shaped flow guiding strips vertically fixed to the inner wall of the cabinet body and located on the upper and lower sides of the flow guiding cover, respectively. The open side of the first U-shaped flow guiding strip is fixed to the corresponding inner wall of the cabinet body so that a first longitudinal air duct is formed between the inside of the first U-shaped flow guiding strip and the corresponding inner wall of the cabinet body.

[0009] The upper and lower ends of the first U-shaped guide strip are respectively sealed and inserted into the lower side of a transverse support beam located above the guide shield and the upper side of the guide shield. The upper and lower ends of the lower first U-shaped guide strip are respectively sealed and inserted into the lower side of the guide shield and the upper side of a transverse support beam located below the guide shield.

[0010] Preferably, at least one vertically distributed second U-shaped guide strip is provided between any two adjacent transverse support beams. The open side of each second U-shaped guide strip is fixed to the corresponding inner wall of the cabinet body so that the interior of each second U-shaped guide strip and the corresponding inner wall of the cabinet body form a second longitudinal air duct. The upper and lower ends of each second U-shaped guide strip are respectively sealed and inserted into the lower side of the upper transverse support beam and the upper side of the lower transverse support beam.

[0011] Preferably, the cabinet body includes a frame, a top cover and a bottom cover respectively fixed at the top opening and the bottom opening of the frame, a front door located at the front opening of the frame and openable, a rear door located at the rear opening of the frame and openable, and two side covers respectively fixed at the left and right openings of the frame.

[0012] Preferably, the top cover has a first wire passage cavity, and the first wire passage cavity is also provided with two first sliding covers symmetrically distributed front and back. The two first sliding covers are laterally and movably connected to the outer wall or inner wall of the top cover so that they both have the function of forward and backward translation. The opposite side edges of the two first sliding covers are also fixed with a first pull strip that cooperates with each other.

[0013] Preferably, a second wire passage cavity is provided on the rear side of the bottom cover, and two second sliding covers are provided at the second wire passage cavity. The two second sliding covers are laterally and movably connected to the outer wall or inner wall of the bottom cover so that they both have the function of forward and backward translation.

[0014] Preferably, the bottom cover is also fitted with a removable plug.

[0015] Compared with the prior art, the advantages of this utility model are as follows: This utility model uses the cooperation between the air guiding component and each horizontal support beam to evenly divide the single stream of cold air entering the cabinet into multiple streams of cold air, thereby enabling the cabinet to have an air guiding function. This allows the cold air to be fully and evenly diffused to all positions inside the cabinet, thereby effectively improving the heat dissipation effect and ensuring that the cold air can cool all electrical or electronic equipment. This breaks through the height limitation of the cabinet and enhances its practicality. Attached Figure Description

[0021] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0022] like Figures 1-4As shown, a multi-airflow heat dissipation cabinet includes a cabinet body and two positioning frames symmetrically arranged on the left and right sides inside the cabinet body. The left or right inner wall of the cabinet body is provided with an air outlet 11 and an air inlet 12 distributed vertically. The space between the two positioning frames is used to install electrical equipment.

[0023] In use, the integrated air conditioner 5 is fixed on the outer wall of the side where the air outlet 11 or air inlet 12 is located, and the air outlet 51 and air inlet grille of the integrated air conditioner 5 are aligned with the air outlet 11 and air inlet 12 respectively. When the integrated air conditioner 5 is working, the hot air in the cabinet is drawn into the integrated air conditioner 5 through the air inlet 12 and air inlet grille to release heat and generate cold air. The cold air is blown out through the air outlet 51 and enters the cabinet through the air outlet 11, thereby realizing circulating cooling. The above structure and principle are all existing technologies.

[0024] The feature of this utility model is that the positioning frame includes multiple transverse support beams 7 arranged horizontally and distributed in parallel from top to bottom, and two vertical and detachable longitudinal mounting strips 10 fixed between the multiple transverse support beams 7 and distributed front and back respectively. The air outlet hole 11 and the air inlet hole 12 are both located between any two adjacent transverse support beams 7.

[0025] The transverse cross-section of the transverse support beam 7 is shaped like a "Z". The open side of each transverse support beam 7 is fixed to the corresponding inner wall of the cabinet so that a transverse air duct 73 is formed between the interior of each transverse support beam 7 and the corresponding inner wall of the cabinet. The bottom of each transverse support beam 7 is provided with multiple through holes 71 arranged from front to back for fixing the longitudinal mounting strip 10.

The open side of the first U-shaped flow guiding strip 62 is fixed to the corresponding inner wall of the cabinet so that a first longitudinal air duct 64 is formed between the inside of the first U-shaped flow guiding strip 62 and the corresponding inner wall of the cabinet.

[0027] The upper and lower ends of the first U-shaped guide strip 62 are respectively sealed and inserted into the lower side of a transverse support beam 7 located above the guide shield 61 and the upper side of the guide shield 61. The upper and lower ends of the lower first U-shaped guide strip 62 are respectively sealed and inserted into the lower side of the guide shield 61 and the upper side of a transverse support beam 7 located below the guide shield 61.

[0028] Between any two other adjacent transverse support beams 7, there is at least one vertically distributed second U-shaped guide strip 63. The open side of each second U-shaped guide strip 63 is fixed to the corresponding inner wall of the cabinet so that a second longitudinal air duct 65 is formed between the interior of the second U-shaped guide strip 63 and the corresponding inner wall of the cabinet. The upper and lower ends of each second U-shaped guide strip 63 are respectively sealed and inserted into the lower side of the upper transverse support beam 7 and the upper side of the lower transverse support beam 7.

[0029] The cabinet body includes a frame 1, a top cover 9 and a bottom cover 8 respectively fixed to the top opening and bottom opening of the frame 1, a front door 3 located at the front opening of the frame 1 and openable, a rear door 4 located at the rear opening of the frame 1 and openable, and two side covers 2 respectively fixed to the left and right openings of the frame 1.

[0030] Both the air outlet 11 and the air inlet 12 are located in one of the side covers 2.

[0031] The open side of each transverse support beam 7, the open side of each first U-shaped guide strip 62, and the open side of each second U-shaped guide strip 63 are all fixed to the inner wall of a side cover 2 on the same side.

[0032] The top cover 9 has a first wire passage cavity 91. The first wire passage cavity 91 is also provided with two first sliding covers 13 symmetrically distributed front and back. The two first sliding covers 13 are laterally and movably connected to the outer wall or inner wall of the top cover 9 so that they both have the function of forward and backward translation. The opposite side edges of the two first sliding covers 13 are also fixed with a first pull strip 14 that cooperates with each other.

[0033] The bottom cover 8 has a second wire passage cavity 81 on the rear side. The second wire passage cavity 81 also has two second sliding covers 15 symmetrically distributed front and back. The two second sliding covers 15 are laterally and movably connected to the outer or inner wall of the bottom cover 8 so that they both have the function of forward and backward translation. The opposite side edges of the two second sliding covers 15 are also fixed with a second pull strip 16 that cooperates with each other.

[0034] The bottom cover 8 is also fitted with a removable plug 17.

[0035] Working principle:

[0036] When the cold air comes out of the air outlet 11, it first enters and fills the interior of the air guide shroud 61 in the air guide assembly 6, and then enters the two transverse air ducts 73 formed by the two first U-shaped air guide strips 62 through the first longitudinal air ducts 64. The air then enters the two transverse support beams 7 located on the upper and lower sides of the air guide shroud 61, and is then blown evenly into the cabinet body through the through holes 71 on each transverse support beam 7. The through holes 71 serve two purposes here: first, to fix the longitudinal mounting strips 10, and second, to blow out the cold air, achieving two goals at once.

[0037] Next, the cold air located in each first longitudinal air duct 64 will enter the second longitudinal air duct 65 formed by a second U-shaped guide bar 63 connected to it in sequence into the transverse air duct 73 formed by each of the remaining transverse support beams 7. Finally, it will also be blown evenly into the cabinet through the through holes 71 on each transverse support beam 7. In this way, the original single mainstream cold air can be evenly divided into multiple branch cold air and blown into the cabinet, thereby effectively and comprehensively cooling the electrical equipment installed inside the cabinet.

[0038] By manually moving any of the first pull bars 14 or any of the second pull bars 16, a corresponding first sliding cover 13 or a second sliding cover 15 can be moved forward or backward, thereby creating a gap between the two first pull bars 14 or the two second pull bars 16 so that the power supply line can extend into the cabinet body through the first cable passage cavity 91 or the second cable passage cavity 81.

[0039] This utility model utilizes the cooperation between the airflow guiding component 6 and each transverse support beam 7 to evenly divide the single stream of cold air entering the cabinet into multiple streams of cold air, thereby enabling the cabinet to have an airflow guiding function. This allows the cold air to be fully and evenly diffused to all parts of the cabinet, effectively improving the heat dissipation effect and ensuring that the cold air can cool all electrical or electronic equipment. This breaks through the height limitation of the cabinet and enhances its practicality.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
