Description

Technical Field

[0001] This utility model belongs to the field of liquid chiller technology, and more specifically, it relates to a low-noise liquid chiller unit. Background Technology

[0002] With the development of technology, liquid cooling units are gradually being applied to various production fields. There are two main cooling methods for liquid cooling units: air cooling and liquid cooling. Air cooling is mainly used in applications with low cooling density and features simple structure and small equipment size. Liquid cooling has strong heat transfer capacity and is often used in equipment that generates a large amount of heat, such as for heat dissipation in energy storage batteries.

[0003] Application number CN202220268834.0 discloses a liquid-cooled unit. The liquid-cooled unit includes a frame, a heat dissipation device, an electrical control system, and a cooling system. The frame has three layers: the heat dissipation device is located on the upper layer, the electrical control system is located on the middle layer, and the cooling system is located on the lower layer. This design avoids the safety hazards of water-electricity contact and is also convenient for operation and maintenance.

[0004] Based on the above patent searches and understanding of the applications of existing liquid cooling units:

[0005] Currently, the operating components such as fans and circulating pumps inside the unit generate continuous mechanical noise. Traditional chassis structures are not well-sealed, making it easy for noise to spread outwards. At the same time, they lack specialized sound insulation and buffering designs, making it impossible to effectively reduce internal noise. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a low-noise liquid cooling unit, which solves the problems of continuous mechanical noise generated by operating components such as fans and circulating pumps inside existing units, insufficient sealing of traditional chassis structures, easy noise transmission, and lack of dedicated sound insulation and buffer design, making it impossible to effectively reduce internal noise.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A low-noise liquid cooling unit includes a chassis; a through slot is provided at the middle of the rear end of the chassis, and a heat sink is fixedly installed in the through slot. A fan is fixedly installed at the rear end of the heat sink. A sound insulation cotton is symmetrically arranged on the left and right sides inside the chassis. A semi-conical buffer groove is provided on the inner side of each sound insulation cotton. A door is rotatably connected to the right side of the front end of the chassis. A conical groove is provided at the rear of the door, and a sealing strip is provided at the rear edge of the door. When the door is closed at the front end of the chassis, the sealing strip fills the front edge of the chassis interior.

[0009] According to one embodiment of the present invention, a circulation pump is fixedly installed at the upper front end of the heat sink, and a liquid cooling heat dissipation assembly is fixedly installed at the upper front end of the heat sink. The circulation pump is connected to the liquid cooling heat dissipation assembly through a pipeline.

[0010] According to one embodiment of the present invention, a mounting slot is provided at the top center of the chassis, and the top of the liquid cooling heat dissipation assembly is fixedly connected to the bottom of the cooling base.

[0011] According to one embodiment of the present invention, the cooling base is located inside the chassis, and the top of the cooling base is located in the mounting slot of the chassis.

[0012] According to one embodiment of the present invention, a fan is fixedly installed at the middle position of the front end of the cooling base, and the fan is located at the front center position inside the chassis.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The sound insulation cotton symmetrically arranged on the left and right sides inside the chassis has a semi-conical buffer groove on its inner side, which can significantly increase the contact area between the sound insulation cotton and noise. This can more efficiently absorb the mechanical noise generated by the operation of the fan, circulating pump and blower inside the unit, and reduce the reflection and propagation of noise inside the chassis. The sealing strip at the rear edge of the chassis door can tightly fill the gap at the front edge of the chassis when the chassis door is closed, effectively improving the overall sealing of the chassis and blocking the leakage of noise outward from the propagation path, further reducing the noise impact of the unit on the external environment during operation. The conical groove set at the rear of the chassis door and the semi-conical buffer groove of the sound insulation cotton work together to form a multi-layer noise buffer structure, which can buffer and weaken the noise inside the chassis multiple times, further improving the noise reduction effect.

[0015] 2. The circulating pump is connected to the liquid cooling unit through pipelines, which can stably drive the coolant to circulate within the liquid cooling unit, providing continuous and efficient heat exchange and cooling for the cooling base. This ensures that the components placed on the cooling base can be cooled down in time to meet the cooling requirements. The fan at the rear of the cooling base can quickly cool the cooling base, and the cooling base transfers the low temperature to the liquid cooling unit, assisting the liquid cooling unit in improving its heat dissipation efficiency. At the same time, the fan at the front of the cooling base can directly provide auxiliary cooling to the cooling base, forming a synergistic heat dissipation mechanism with the liquid cooling system. This effectively ensures the stable and reliable heat dissipation performance of the unit as a whole, avoiding the impact of insufficient heat dissipation on the unit's operating efficiency or the normal operation of the components to be cooled.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. Example:

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] This utility model provides a low-noise liquid cooling unit, including a chassis 1; a through groove is provided at the middle of the rear end of the chassis 1, and a heat sink 101 is fixedly installed in the through groove of the chassis 1. A fan 102 is fixedly installed at the rear end of the heat sink 101. A sound insulation cotton 107 is symmetrically arranged on the left and right sides inside the chassis 1. A semi-conical buffer groove is provided on the inner side of each sound insulation cotton 107. A door 2 is rotatably connected to the right side of the front end of the chassis 1. A conical groove is provided at the rear end of the door 2, and a sealing strip 201 is provided at the rear edge of the door 2. When the door 2 is closed at the front end of the chassis 1, the sealing strip 201 fills the front edge of the interior of the chassis 1.

[0027] A circulation pump 103 is fixedly installed at the upper front end of the heat sink 101, and a liquid cooling heat sink 104 is fixedly installed at the upper front end of the heat sink 101. The circulation pump 103 is connected to the liquid cooling heat sink 104 through pipelines. A mounting slot is provided at the middle of the top of the chassis 1. The top of the liquid cooling heat sink 104 is fixedly connected to the bottom of the cooling base 105.

[0028] The cooling base 105 is located inside the chassis 1, and the top of the cooling base 105 is located in the mounting slot of the chassis 1. A fan 106 is fixedly installed at the middle of the front end of the cooling base 105, and the fan 106 is located at the front center inside the chassis 1.

[0029] When using:

[0030] Place the chassis 1 in a flat, well-ventilated working area, ensuring that there are no obstructions around the chassis 1 to avoid hindering the exhaust path of the fan 102 and the airflow of the fan 106, thus creating basic conditions for heat dissipation and noise control of the unit.

[0031] The component to be cooled is placed on top of the cooling base 105 and fixed. The circulating pump 103 drives the coolant to circulate in the liquid cooling heat dissipation assembly 104 to exchange heat and cool the cooling base 105. During this process, the fan 102 is started to cool the heat dissipation base 101. The heat dissipation base 101 transfers the temperature to the liquid cooling heat dissipation assembly 104 to assist the liquid cooling heat dissipation assembly 104 in completing the cooling. When the fan 106 is started, it can assist in cooling the cooling base 105.

[0032] Rotate the door 2 on the right side of the front of the chassis 1 to close it at the front of the chassis 1. At this time, the sealing strip 201 at the rear edge of the door 2 will automatically fill the gap at the front edge of the chassis 1, thus sealing the chassis 1 and reducing noise leakage. At the same time, the noise inside the chassis 1 will be buffered and reduced by the semi-conical buffer grooves of the sound insulation cotton 107 on both sides of the chassis 1 and the conical groove of the door 2. The semi-conical buffer grooves of the sound insulation cotton 107 can increase the contact area between the sound insulation cotton 107 and the noise, and more efficiently absorb the mechanical noise generated by the operation of the fan 102, fan 106 and circulating pump 103 inside the unit.

[0033] Although this application has been described with reference to the foregoing embodiments, those skilled in the art will understand that various changes can be made without departing from the spirit and scope of this application as defined by the appended claims. While this specification contains details of many specific implementations, these should not be construed as limiting the scope of the claims, but rather as descriptions of features specific to particular embodiments. The scope of this application is defined by the appended claims and their equivalents, and is not limited to the embodiments described above.
