Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to an easy-to-maintain liquid cooling unit. Background Technology

[0002] With the increasing adoption of liquid cooling technology in data centers, energy storage systems, and other applications, the need for rapid maintenance of fan modules is becoming increasingly prominent. Traditional liquid cooling units use a chassis frame with top screws to secure the fan. In actual use, it has been found that replacing the fan requires first removing the frame cover and surrounding cables, and then loosening screws in multiple directions, which limits the operating space and makes it difficult to access tools.

[0003] To address the aforementioned issues, patent CN208402182U proposes a pull-out fan structure, integrating the ion generator and air supply components into a pull-out bracket for overall mobility. However, practical applications have revealed the following shortcomings: the pull-out bracket integrates non-essential maintenance components such as the electrical control box and ion generator, requiring the entire fan to be pulled out for cleaning or replacement, increasing track load and the risk of damage to precision components; furthermore, the pull-out bracket relies solely on upper and lower pull-out plates to fix the long, narrow air supply component, making it prone to lateral swaying in vibration environments, leading to track jamming; and when using a single-sided locking mechanism, a clearance exists between the pull-out bracket and the cabinet side wall, making it susceptible to front-to-back displacement under full load, affecting the stability of the power connectors.

[0004] The aforementioned shortcomings result in low maintenance efficiency and high failure rate in existing pull-out structures in industrial applications, especially in dusty environments where frequent maintenance of the fan impeller is required. Therefore, an easy-to-maintain liquid-cooled unit is needed to solve these problems. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides an easy-to-maintain liquid cooling unit. The fan assembly can be pulled out for easy movement, maintenance, and replacement. Furthermore, it is secured with baffles to ensure the stability of the fan assembly, making it highly practical.

[0006] The present invention adopts the following technical solution: This utility model provides an easy-to-maintain liquid cooling unit, including a chassis, a fan assembly, and a baffle that is detachably connected to the chassis. The chassis has a receiving groove formed on its top, and the receiving groove has an opening on at least one side. The fan assembly is configured to be slidably disposed in the receiving groove. The baffle is configured to be detachably coupled to the chassis to fix the fan assembly. When the baffle is attached to the opening, the fan assembly is securely fixed in the receiving groove; when the baffle is separated from the opening, the fan assembly can be pulled and moved through the opening to facilitate the overall disassembly and maintenance of the fan assembly.

[0007] The above technical solution can be further improved as follows: Furthermore, the baffle is detachably fixed to the chassis by means of fasteners.

[0008] In a preferred embodiment, two baffles are provided and are spaced apart on both sides of the receiving groove along a first direction.

[0009] Furthermore, the baffle has a limiting structure extending along the first direction to securely fix the fan assembly within the receiving groove; specifically, the limiting structure includes: a pressing section adapted to press against the fan assembly; and a guide section configured to extend obliquely toward the fan assembly.

[0010] Furthermore, the baffle and the chassis are provided with a positioning protrusion and a positioning slot that cooperate with each other, one of the positioning protrusion and the positioning slot being disposed on the baffle and the other being disposed on the chassis.

[0011] Furthermore, the bottom of the receiving groove is provided with a plurality of spaced support bars, which are located on the same plane to jointly support the fan assembly.

[0012] Furthermore, the fan assembly includes a base plate and a plurality of axial fans fixed on the base plate, wherein the plurality of axial fans are arranged sequentially along the length direction of the base plate.

[0013] Furthermore, a cooling component is configured inside the chassis, the receiving slot is configured on the top of the chassis, and the bottom of the receiving slot has an air duct connecting the fan component and the cooling component.

[0029] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0030] Please see Figures 1 to 6As shown, this utility model provides an easy-to-maintain liquid cooling unit 100, including a chassis 1, a fan assembly 2, and a baffle 3 detachably connected to the chassis 1. The baffle 3 and the chassis 1 define a receiving groove 11 suitable for receiving the fan assembly 2. At least one side of the receiving groove is provided with an opening for the fan assembly 2 to move out in a first direction. When the baffle 3 is engaged with the opening, the fan assembly 2 is securely fixed within the receiving groove 11, ensuring the stability of the connection between the fan assembly 2 and the chassis 1. When the baffle 3 is separated from the chassis 1, it can be pulled and moved through the opening for easy disassembly and assembly onto the chassis 1, improving the convenience of cleaning and maintenance of the fan assembly 2. In this embodiment, the fan assembly 2 adopts a modular structure design, is thin and light, and has a small volume, facilitating the pulling and moving of the fan assembly 2. The fan assembly 2 is positioned on the top of the chassis 1, and its design conforms to ergonomic principles, providing operators with an upright working posture and effectively alleviating fatigue caused by bending over.

[0031] like Figure 1-6 As shown, the baffle 3 is detachably fixed to the housing 1 by means of a fastener. Preferably, the fastener can be a clip, a fastening bolt, etc. In this embodiment, the fastener is a fastening bolt. The baffle 3 is fixed to the housing 1 by the fastening bolt. When it is necessary to remove the fan assembly 2, it is only necessary to remove the fastening bolt to separate the baffle 3 from the housing 1, thereby pulling the fan assembly 2 out of the receiving slot 11 in the first direction, which facilitates the maintenance and replacement of the fan assembly 2.

[0032] like Figure 3 and Figure 6As shown, the baffle 3 has a limiting structure 4 extending along a first direction, which allows the fan assembly 2 to be securely fixed within the receiving groove 11 when the baffle 3 is attached to the housing 1. Specifically, the limiting structure 4 includes a pressing section 41 adapted to press against the fan assembly 2; and a guide section 42 configured to extend obliquely toward the fan assembly 2, the guide section 42 extending toward the fan assembly 2 at an angle of 5-25°, and the pressing section 41 pressing against the fan assembly 2. When the baffle 3 is installed in the housing 1, the guide section 42 acts as a guide, ensuring that the pressing section 41 presses against the upper surface of the fan assembly 2, thereby guaranteeing the stability of the fan assembly 2 installation. Additionally, a snap-fit ​​structure 5 is provided between the baffle 3 and the housing 1 to guide their engagement. The snap-fit ​​structure 5 includes a positioning protrusion 51 and a positioning slot (not shown in the figure) that cooperate with each other. One of the positioning protrusion 51 and the positioning slot is disposed on the baffle 3, and the other is disposed on the chassis 1. In this embodiment, the positioning protrusion 51 is disposed at the bottom of the baffle 3, and the positioning slot is disposed on the chassis 1. When the baffle 3 is installed on the chassis 1, the positioning protrusion 51 at the bottom of the baffle 3 will be embedded in the positioning slot, thereby enabling the baffle 3 and the chassis 1 to be quickly aligned and installed together, improving the disassembly and assembly efficiency of the fan assembly 2, and facilitating maintenance and replacement.

[0033] Of course, as a preferred embodiment, two baffles 3 are provided and are spaced apart on both sides of the casing 1 along the first direction. In this way, the fan assembly 2 can be moved out from either side, further improving the convenience of maintenance and replacement of the fan assembly 2.

[0034] like Figures 2-5As shown, the fan assembly 2 includes a base plate 21 and a plurality of axial flow fans 22 fixed on the base plate 21. The plurality of axial flow fans 22 are arranged sequentially along the length direction of the base plate 21. A cooling assembly 6 is disposed inside the chassis 1. The receiving slot 11 is disposed on the top of the chassis 1, and the bottom of the receiving slot 11 has an air duct connecting the fan assembly 2 and the cooling assembly 6, so as to exhaust hot air from the top of the chassis 1 and improve the air cooling effect. In this embodiment, the cooling assembly 6 includes a compressor 61, an evaporator 62, an expansion tank 63, a liquid storage tank 64, and two The heat exchangers 65, in this embodiment, operate on the same principle as existing refrigeration systems, so we will not go into detail here. Two of the heat exchangers 65 are condensers, and both are constructed with hollow mesh structures to ensure the flow of coolant within the refrigeration assembly 6. Gaps are formed between the mesh structures to allow airflow, enabling heat exchange between the heat exchangers 65 and the external airflow, thus ensuring the cooling effect of the refrigeration unit. The two heat exchangers 65 are arranged at an angle and symmetrically below the fan assembly 2, which increases the heat exchange area and improves cooling efficiency. Preferably, a handle is provided on the base plate 21 to facilitate the pulling out of the fan assembly 2, improving ease of use. Furthermore, multiple spaced support bars 7 are arranged at the bottom of the receiving groove 11, spaced along a second direction perpendicular to the first direction, and all support bars 7 are on the same plane to jointly support the fan assembly 2, thereby ensuring the stability of the fan assembly 2 and its suction effect.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
