The heat dissipation design of the notebook computer

         Whether it is a thin and light notebook or a high-performance standalone display, besides performance, heat dissipation is also a key focus of consumers.  

         Temperature is a crucial factor in determining the thickness of notebook computers. After years of development, the reduction in heat generation of core hardware and the improvement of the efficiency of heat dissipation modules have made notebook computers develop from heavy to light and thin. Now we can see products with fanless designs. , At the same time, you can also find high-performance products with heavy models for the purpose of strong heat dissipation.

         The fanless design makes the appearance of the notebook more complete and it is not easy to accumulate dust inside  

         Of course, fanless design notebook products will gradually become the mainstream of the thin and light notebook market, but due to the compromise between performance and power consumption, fanless products have reservations in terms of performance compared to traditional notebooks, but the heat generation problem still exists. This calorific value is similar to that of a mobile phone or tablet. Therefore, whether it is a traditional notebook or a fanless design product, a corresponding heat dissipation design is required.  

         Which heat dissipation design is worth noting  

         How can the heat dissipation of the notebook computer be reasonable? The following three conditions need to be met: first, have a large enough heat dissipation space; second, the design of the heat dissipation duct must be reasonable; third, the high-heating components cannot be too concentrated. With regard to these three seemingly simple heat dissipation requirements, it is really not easy for a laptop to do a good job.  

         Talking about the problem of heat dissipation space, the advantages and characteristics of notebook computers compared to traditional desktops are thin and light. Due to the narrow internal space of the notebook body, its heat dissipation capacity is also limited to a certain extent. Even today’s thin and light notebooks are equipped with low-power processors. The heat dissipation will not be too good. Then, the cooling space of the notebook is limited, and the design of the cooling air duct becomes the key to its cooling performance.  

         Good cooling air duct design is very important. 

         Having a good cooling air duct design is the rational use of the internal space of the machine body. The positions of the air outlet and the air inlet are very important. If the two are arranged improperly, or tightly or blocked, it will inevitably cause problems such as poor heat dissipation. In severe cases, electronic components may be overheated and damaged. Therefore, the high-heating originals cannot be too concentrated, and the distributed layout can effectively prevent the high temperature siltation in the body and cause hardware failure.

         In addition to stabilizing the fuselage, the feet also enhance the air circulation at the bottom of the fuselage  

         The bottom of the laptop body is generally equipped with feet, high or low, their function is to ensure that there is space at the bottom of the fuselage for air circulation, so that a large amount of heat does not accumulate here. Although notebook computers have such a design, it does play a role in heat dissipation, but a little height is not so effective at some point, and many users think of using a heat dissipation base to enhance the heat dissipation effect.  

         In fact, the most basic principle of the heat dissipation base is to increase the air circulation at the bottom of the notebook, so basically all the heat dissipation bases are designed for ventilation on the bottom side of the notebook. Some products do not have fans and rely on natural wind to drive the air flow; most products are equipped with fans for air supply, there are one, two or more. Because most notebook computers have ventilation windows at the bottom of the fuselage, a raised or combined cooling base can indeed send more cold air to the cooling fan inside the fuselage to achieve the purpose of improving heat dissipation efficiency.  

         The bottom of the fuselage is designed with a heat dissipation window for better heat dissipation effect.  

         In addition to the need for heat dissipation at the bottom of the notebook, the keyboard surface of the fuselage is also the main part of the heat dissipation. As we all know, the hot air moves upward, and the heat generated by the internal hardware of the notebook computer can be dissipated through the keyboard surface. Therefore, the notebook keyboard is not a completely compact design. The keyboards of many products have a grid design similar to a ventilation window. This is to discharge internal heat through the keyboard surface upwards. This is often used as a passive heat dissipation compensation in addition to active heat dissipation.

             In addition to active heat dissipation, there is also passive heat dissipation through the keyboard surface  

         After all, the efficiency of natural heat dissipation is not fast. Sometimes when using a laptop, we find that the heat in the palm rest or the keyboard is extremely high, and sometimes it is even too hot. This is related to the location of the heat source and the exhaust ability of the internal cooling fan. The factory has been set in this way, we can not change its essence, so it is feasible to give it external force to improve heat dissipation.

         Optimization of power consumption in software is also very important  

         But this is not a problem that can be solved by hardware alone. It requires software to cooperate. There is a very important function in the pre-installed operating system of the notebook computer, that is, power management. Windows, Linux, OS X and other systems are equipped with power management functions. The biggest function is to adjust the hardware operation status according to the user's usage. So as to achieve the purpose of reducing power consumption and heat generation. Therefore, installing the correct power management driver or software in the system can improve the heating of the notebook computer and extend the battery life.
