Technical Field
[0001] This application belongs to the field of heat sink technology for heat-generating elements, specifically a kind of luminescent condensing nano heat sink. Background Technology
[0002] With the rapid development of technology, the power density of various devices is increasing exponentially. In modern industry and electronics, condensers and radiators, as key heat dissipation devices, are widely used in many industries such as power, electronics, and automobiles.
[0003] Heat sinks, as a highly efficient heat dissipation device, play an indispensable role in many electronic devices. They are usually made of metal and, thanks to their excellent thermal conductivity, can quickly absorb the heat generated during device operation. These heat sinks are widely used in computer CPUs, graphics cards, and LED lighting fixtures, among other devices.
[0004] However, traditional heat sinks have limited heat dissipation area and their heat conduction efficiency is difficult to improve further. Heat accumulates inside the heat sink, causing localized overheating of the equipment and even structural damage, thus reducing its service life. Summary of the Invention
[0005] The purpose of this application is to provide a luminescent condensing nano heat sink to address the problems mentioned above, such as the limited heat dissipation area of traditional heat sinks, the difficulty in further improving heat conduction efficiency, the accumulation of heat inside the heat sink, leading to local overheating of the equipment, and even structural damage and reduced service life.

[0008] In a preferred embodiment, the interior of the high thermal conductivity metal substrate has a plurality of nanoscale microchannels, which are distributed in a mesh-like pattern.
[0009] By adopting the above technical solution, it possesses an extremely high specific surface area. When the cooling medium flows in the nanoscale microchannels, the heat exchange area between the cooling medium and the nanoscale heat sink body is greatly increased. Simultaneously, it enables the cooling medium to form turbulence within the channels, enhancing its heat transfer capacity and allowing it to quickly remove heat from the heat sink, thus improving heat dissipation efficiency.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0020] Reference Figure 1-2 A luminescent energy-condensing nano heat sink includes a nano heat sink body 1, a high thermal conductivity metal base layer 2 at the lower end of the nano heat sink body 1, a carbon nanotube reinforcement layer 3 at the upper end of the high thermal conductivity metal base layer 2, a phase change material filling layer 4 at the upper end of the carbon nanotube reinforcement layer 3, a fluorescent nano coating 7 at the upper end of the phase change material filling layer 4, and a plurality of heat dissipation fins 5 on the surface of the fluorescent nano coating 7. The high thermal conductivity metal base layer 2 and the carbon nanotube reinforcement layer 3 ensure rapid heat transfer, the phase change material filling layer 4 can effectively regulate the temperature, and the fluorescent nano coating 7 enhances the heat dissipation effect. The multi-layer composite structure design improves the heat dissipation capacity of the nano heat sink body 1, reduces the probability of heat damage to the equipment, and extends its service life.
[0021] Reference Figure 2 The high thermal conductivity metal base layer 2 has several nanoscale microchannels 6 internally arranged in a mesh pattern. These microchannels have an extremely high specific surface area, which greatly increases the heat exchange area between the cooling medium and the nanoscale heat sink body 1 when the cooling medium flows through them. Simultaneously, it enables turbulence within the channels, enhancing the heat transfer capacity of the cooling medium and allowing it to quickly remove heat from the heat sink, thus improving heat dissipation efficiency.
[0022] Reference Figure 1-2 The phase change material filling layer 4 is made of polyol, which has strong thermal stability and will not easily decompose in high temperature environment, thus improving stability. In addition, it has a large latent heat of phase change, which can efficiently store and release heat and improve heat dissipation efficiency.
[0023] Reference Figure 1-2 The outer surface of the nano heat sink body 1 is coated with an anti-condensation coating, which makes the surface temperature distribution of the nano heat sink body 1 more uniform, reduces condensation caused by local low temperature, avoids corrosion and short circuit problems caused by condensation, and extends the service life of the nano heat sink body 1.
[0024] The implementation principle of the luminescent energy-condensing nano heat sink embodiment of this application is as follows:
[0025] The high thermal conductivity metal base layer 2 can quickly transfer heat from the heat source to all parts of the heat sink, ensuring high efficiency in heat conduction. Carbon nanotubes possess excellent mechanical properties and thermal conductivity, enhancing the overall strength of the heat sink and further improving heat conduction efficiency. The phase change material filling layer 4 undergoes a phase change from solid to liquid when it absorbs heat to its phase change temperature, absorbing a large amount of latent heat and effectively regulating the temperature of the heat sink. When the temperature decreases, the phase change material changes back from liquid to solid, releasing the stored heat. This phase change process allows the nano-heat sink body 1 to maintain a relatively stable temperature within a certain temperature range, improving the uniformity of heat dissipation. High-efficiency heat dissipation is achieved through fluorescence emission and promotion of air convection. Simultaneously, its superhydrophobicity makes it difficult for dust and dirt to adhere to the surface; they can be easily removed by natural wind or slight vibration, achieving a self-cleaning function and ensuring that the surface of the nano-heat sink body 1 remains clean, maintaining good heat dissipation performance.
[0026] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such 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 application.
