Description

Technical Field

[0001] This utility model relates to the field of notebook heat dissipation mechanisms, specifically a heat dissipation insulating sheet for notebooks. Background Technology

[0002] With the rapid development of technology, laptops, with their portability and powerful performance, have become indispensable tools for people's daily work, study, and entertainment. However, high-performance laptops generate a lot of heat during operation, and how to effectively dissipate heat has become a key issue in ensuring the stable operation of laptops and extending their lifespan.

[0003] Traditional laptop cooling primarily relies on built-in cooling fans and copper heat pipes. The cooling fan removes heat by accelerating airflow, while the copper heat pipes conduct heat from the heat source to the cooling fins, and then the fan blows the heat out of the chassis.

[0004] From the perspective of heat dissipation efficiency, the aforementioned cooling methods suffer from several drawbacks. After prolonged use, cooling fans tend to accumulate dust, leading to a decrease in fan speed and airflow, thus affecting heat dissipation. Furthermore, the operation of the fan increases the laptop's workload. Additionally, the traditional layout of heat pipes and fins is relatively fixed, making it difficult to flexibly adjust to the complex internal structure and heat source distribution of a laptop.

[0022] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0023] Reference Figure 1 , Figure 2 and Figure 3 As shown, a heat dissipation insulating sheet for a laptop includes a laptop casing 1. A heat sink 2 is mounted on the lower surface of the laptop casing 1, and the heat sink 2 is fixedly attached to the laptop casing 1. Heat dissipation feet 3 are mounted on the four corners of the lower surface of the heat sink 2, and the heat dissipation feet 3 are inserted and fixed to the heat sink 2. Several sets of inner bent tube assemblies 4 are also mounted above the heat sink 2. One end of each inner bent tube assembly 4 is fixedly connected to the heat sink 2, and the other end of each inner bent tube assembly 4 is fitted with an inner heat-conducting component 5, which is sleeved and fixedly connected to the inner bent tube assembly 4. The heat sink 2, attached to the lower surface of the laptop casing 1, can directly absorb the heat generated by the laptop. The heat dissipation feet 3 increase the heat dissipation area and improve heat dissipation efficiency. The inner bent tube assemblies 4 and the inner heat-conducting components 5 are connected to the interior of the laptop casing 1 and are attached to the areas of the laptop circuit board where heat is severe, further enhancing heat conduction and dissipation, making heat dissipation more uniform.

[0024] Reference Figure 2As shown, the heat sink 2 includes an outer frame 21 and a middle frame 22. The middle frame 22 is installed in the middle of the outer frame 21 and is fixedly connected to the outer frame 21. The outer frame 21 serves to protect and support the middle frame 22, which is the main heat dissipation structure. The two are fixedly connected to form a stable heat dissipation unit, improving the structural stability and heat dissipation performance of the heat sink 2. The middle frame 22 includes a main frame 221 and a grid plate 222. The grid plate 222 is evenly installed in the main frame 221 and is fixedly connected to the main frame 221. The design of the grid plate 222 increases the surface area of ​​the heat sink 2, allowing heat to dissipate more quickly. The main frame 221 provides support for the grid plate 222, ensuring the stability of the grid plate 222 and also facilitating heat conduction.

[0025] Reference Figure 4 As shown, the heat dissipation foot 3 includes a metal base 31 and arc-shaped fins 32. The arc-shaped fins 32 are symmetrically mounted on the upper surface of the metal base 31 and are fixedly connected to the metal base 31. The metal base 31 has good thermal conductivity, enabling it to quickly transfer heat to the arc-shaped fins 32. The design of the arc-shaped fins 32 increases the heat dissipation area and guides airflow, improving heat dissipation efficiency. Several rubber blocks 311 are evenly arranged on the lower surface of the metal base 31. The rubber blocks 311 are glued and fixed to the metal base 31. A central fin 312, which is inserted and connected to the heat sink 2, is installed at the center of the upper surface of the metal base 31. The rubber blocks 311 serve as a buffer and anti-slip element, protecting the surface of the laptop casing 1 from scratches and improving the stability of the heat dissipation insulation sheet. The central fin 312 is inserted and connected to the heat sink 2, enhancing the connection stability and thermal conductivity between the heat dissipation foot 3 and the heat sink 2.

[0026] Reference Figure 3 As shown, the inner bend tube assembly 4 includes a connecting bend tube 41 and a mounting tube 42 for installing the inner heat-conducting component 5. One end of the connecting bend tube 41 is fixed to the outer surface of the outer frame 21, and the mounting tube 42 is integrally formed at the other end of the connecting bend tube 41. The connecting bend tube 41 connects the heat sink 2 and the inner heat-conducting component 5, allowing heat to be transferred between them. The mounting tube 42 provides an installation position for the inner heat-conducting component 5, ensuring the stability of the inner heat-conducting component 5 and also facilitating heat conduction. Moreover, the mounting tube 42 can flexibly adjust its bending angle according to different shapes and layouts of the laptop, making it easier for the inner heat-conducting component 5 to be more precisely positioned where heat dissipation is required.

[0027] Reference Figure 5 and Figure 6As shown, the internal heat-conducting assembly 5 includes a sleeve portion 51, a pressure plate 52, and a thermally conductive insulating sheet 53. The pressure plate 52 is fixedly installed on the lower end face of the sleeve portion 51, and several mating inclined plates 511 connected to the pressure plate 52 are symmetrically arranged on both sides of the sleeve portion 51. The thermally conductive insulating sheet 53 is fitted and installed against the lower end face of the pressure plate 52. The sleeve portion 51 is used to fit and fix with the inner curved tube assembly 4, ensuring the installation stability of the internal heat-conducting assembly 5. The design of the pressure plate 52 and the mating inclined plates 511 allows the thermally conductive insulating sheet 53 to fit tightly against the parts that need heat dissipation, improving the heat conduction efficiency. The thermally conductive insulating sheet 53 can both conduct heat and provide insulation, ensuring the safe operation of the laptop.

[0028] Working principle:

[0029] The outer frame 21 and the middle frame 22 of the heat sink 2 can be made of aluminum alloy, which has good thermal conductivity and light weight. The outer frame 21 is formed by die stamping, while the main frame 221 and the mesh plate 222 of the middle frame 22 can be made by welding or integral molding. The size of the main frame 221 is designed according to the size of the laptop casing 1.

[0030] The metal base 31 of the heat dissipation support 3 is made of copper alloy, which has excellent thermal conductivity. Rubber blocks 311 are evenly adhered to the lower surface of the metal base 31. These rubber blocks 311 can be made of silicone, providing good anti-slip and cushioning properties. The central fin 312 on the upper surface of the metal base 31 is inserted and fixed into the corresponding slot of the heat sink 2. The arc-shaped fins 32 are fixed to the metal base 31 by welding.

[0031] The connecting bend 41 and the laying pipe 42 of the inner bend assembly 4 can be made of copper pipe, which has good thermal conductivity and flexibility. One end of the connecting bend 41 is fixed to the outer side of the outer frame 21 by welding, and the laying pipe 42 is integrally formed and set at the other end of the connecting bend 41.

[0032] The sleeve 51 of the internal heat-conducting component 5 is fitted and fixed to the head of the routing tube 42. By bending the head of the routing tube 42, the thermally conductive insulating sheet 53 of the internal heat-conducting component 5 is adjusted to stably adhere to the location on the circuit board where heat dissipation is required. The thermally conductive insulating sheet 53 can be made of thermally conductive silicone to ensure good thermal conductivity and insulation. In this way, the heat inside the laptop can be stably conducted to the outside through heat conduction.
