Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation modules, in particular to an automatic cleaning heat dissipation module for a notebook computer. Background Art

[0002] The heat dissipation module is usually composed of a radiator, a fan and a heat dissipation channel. The radiator is the main heat dissipation component and is generally made of materials with good thermal conductivity such as copper or aluminum. It can quickly transfer the heat of heat-generating components such as the CPU and GPU to the outside. The fan is the air flow channel in the heat dissipation module. It continuously inhales and exhausts air to take away the heat from the radiator, thereby achieving the heat dissipation effect. The heat dissipation module of a laptop computer is an important part of its heat dissipation system. It is mainly used to dissipate the heat generated when the laptop computer is running and maintain the normal operating temperature of the laptop computer.

[0003] The existing cooling module cannot automatically clean the dust net. Dust and debris will accumulate on the dust net after long-term use, resulting in poor ventilation and affecting the cooling effect. For example, a side-inlet laptop cooling module disclosed in announcement number CN202122493168.9 cannot be automatically cleaned and needs to be cleaned manually. Users need to disassemble and install the dust net by themselves. Improper operation may cause damage, thereby increasing maintenance costs.

[0004] Therefore, it is necessary to invent a notebook computer heat dissipation module that can be automatically cleaned to solve the above problems. Utility Model Content

[0008] Preferably, there are two copper tubes, and a first heat-conducting base plate and a second heat-conducting base plate are fixedly installed on the two copper tubes. A heat-conducting medium is fixedly installed above the first heat-conducting base plate and the second heat-conducting base plate, so that the copper tube has excellent thermal conductivity and can quickly conduct heat away in a short time.

[0009] Preferably, a cooling fan is arranged directly below the dustproof net, and the cooling fan is arranged inside the outer shell. A cleaning brush is arranged above the dustproof net, so that the cooling fan can rotate rapidly to make the air flow, forming a natural convection, and the flowing air takes away the heat, thereby achieving the heat dissipation effect.

[0010] Preferably, the rotating shaft and the sleeve are threadedly connected, and the center line of the rotating shaft coincides with the center line of the sleeve, so that the rotating shaft and the sleeve can be firmly fixed together.

[0011] Preferably, the outer wall of the upper end of the rotating shaft is provided with an external thread, and the inner wall of the sleeve is provided with an internal thread, and the external thread cooperates with the internal thread so that the external thread and the internal thread facilitate threaded disassembly and assembly of the sleeve.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] Through the setting of the rotating shaft and the cleaning brush, the cleaning brush is linked with the cooling fan through the rotating shaft. The rotation of the cooling fan can drive the cleaning brush to rotate synchronously. The bristles of the cleaning brush are in contact with the dustproof net, so the rotation of the cleaning brush can clean the dust and impurities on the surface of the dustproof net in time, thereby avoiding clogging of the dustproof net, maintaining heat dissipation performance, reducing the frequency and difficulty of manual cleaning and maintenance, and simplifying the user's maintenance work.

[0027] Working principle of this utility model:

[0028] Refer to the instruction manual Figure 1-3 When using the utility model, first install the heat dissipation module inside the notebook computer. When the notebook computer is running, the CPU, GPU and other heat-generating components inside it will generate heat. The generated heat is transferred to the heat sink covering the heat-generating components through the first heat-conducting base plate 6, the second heat-conducting base plate 7 and the heat-conducting medium 8, and the heat is further transferred to the heat dissipation fins 3 through the copper tube 4. The heat-conducting liquid in the copper tube 4 transfers the heat to the heat dissipation fins 3. The heat dissipation fins 3 dissipate the heat into the air through heat exchange with the air. At this time, the cooling fan 11 starts to work, sucks in the air around the heat dissipation fins 3, and helps the heat dissipation fins 3 to dissipate the heat. The wind flow generated by the cooling fan 11 takes away the heat on the heat dissipation fins 3 and dissipates the heat into the surrounding air. Through the wind flow heat dissipation, the heat dissipation module can more effectively transfer the heat and dissipate the heat into the air, thereby reducing the temperature of the heat-generating components.

[0029] Refer to the instruction manual Figure 4-6 When the utility model is used, when the heat dissipation module is working, impurities in the air can be blocked by the dustproof net 9 to prevent dust and impurities in the air from entering the interior of the outer shell 1. However, the surface of the dustproof net 9 will absorb dust, and the accumulated dust will block the through holes of the dustproof net 9, thereby affecting the air intake and the heat dissipation effect. Therefore, the sleeve 14 can be aligned with the rotating shaft 12 by hand-tightening the nut 16 and threading it to ensure that the sleeve 14 and the rotating shaft 12 are stably installed. As a result, the rotation of the cooling fan 11 can drive the cleaning brush 17 to rotate synchronously, and the bristles of the cleaning brush 17 are in contact with the dustproof net 9. Therefore, the rotation of the cleaning brush 17 can clean the dust and impurities on the surface of the dustproof net 9 in time, thereby realizing automatic cleaning of the dustproof net 9, thereby preventing the dustproof net 9 from being blocked and maintaining its heat dissipation performance.
