Laptops in living and working outside, plays a very important role. But laptops in terms of heat dissipation, always know more “chicken ribs”. However, good industrial design and workmanship, in the aspect of heat better than general notebook out naturally a lot. Each of us is not necessarily a rich man, however, may not have so much budget to buy a high-end. Don’t worry, the small make up and talk to you about laptop heat dissipation considerations, the use of after you will have a lot of help.
Notebook cooling has a problem, not only affect the normal use and office, appeared frequently automatic shutdown, crashes, and so on and so forth, appear more laptop explosion, cause harm to consumers, and so on and so forth have happened. In 2006, is a very hot summer, a consumer is using laptop suddenly explosion, the notebook to the forefront, triggered a series of battery recall. In fact, the notebook battery explosion culprit is too hot! Now, of course, with a laptop battery raw material improvement, notebook explosion has rarely heard.
Computer according to the heat dissipation work in the manner of cooling can be divided into active cooling and passive cooling two kinds. Active cooling is very simple, is through the heat sink to the CPU as natural heat into the air. Because it is a natural send out quantity of heat, the effect is not very good, the heat dissipation effect is proportional to the size of heat sink. But its biggest advantage is that no extra power consumption, and don’t have to worry about is in danger of fan is broken. That this way of heat dissipation is often used in the space there is no special requirements of military or professional equipment. But for personal use notebook, now almost all adopts passive cooling method, passive cooling by fan cooling device, such as compulsive to heat away from the heat sink, its characteristic is high cooling efficiency, small volume and equipment.
So, notebook of those components will generate heat? We will first thought – processor. In addition to the processor, optical drive (super itself has few), hard drives, monitors, graphics CARDS, northbridge, battery, memory, and so on all is the place that generate heat. Only good will be exported to heat, can very good use notebook computer for a long time.
Laptop heat dissipation, are generally follow the cold air from the bottom of the cooling hole into the notebook inside, cold and hot air flow are formed by internal cooling system, a cooling fan out from the side, and then apply form circulating cooling mode. General design better cooling notebook will also adopt some special air duct diversion design, using the cooling hole position and internal structure layout form better air circulation environment, to strengthen the cooling. However, each manufacturer has its own cooling solutions.
In general, a lot of friends will choose to assist in the notebook radiator cooling. This is indeed a very good solution, but as time passes into the dust in the interior fuselage would more than do not use the radiator.
The heatsink moudle of the laptop
The heat to make a notebook, a rapid evacuation, mainly depends on the advanced and effective cooling technology. The laptop cooling technology mainly include water cooling, heat pipe cooling, plate and shell heat dissipation, etc, which laptop due to the internal space and the limitation of the power consumption, heat pipe cooling technology is one of the most traditional way is currently the most widely used heat dissipation. Heat pipe cooling technique is simply “fan + + cooling plate heat pipe” combination, on the motherboard, CPU card, northbridge etc. Through the cooling pads pass quantity of heat to heat the brass, at the same time in the hot copper pipe at the other end of the high-speed fan will be the heat in the copper pipe to evacuate out, so as to realize the cooling purposes.
Many friends will think double copper tube heat dissipation is better than the single copper tube heat dissipation, but the idea is one-sided. Laptop was considered in the design to use what kind of operating mode, if the power is big, notebook inside the processor, discrete graphics, such as hot big, the engineers will choose pair of brass or copper pipe cooling way. Now super Ben and deformation of PC, have adopted low voltage processor, core graphics, will not produce as much heat, so no equipped with double copper cooling technique. The author also believes that may also be for reasons of reducing body weight, and adopts the single copper tube heat dissipation.
When do not use the radiator, and we will want to other ways to help laptop heat dissipation. For example, when we are in the office on the Internet at ordinary times, can the laptop power supply plan for energy saving mode, will reduce the screen brightness. If equipped with independent video card, when not playing games, discrete graphics can be shut down, thereby reducing energy consumption, to achieve the effect of lower calorific value.
Don’t know if you have the laptop screen directly closed, away into a backpack? When we close the computer directly to the screen directly, the computer will be according to the Settings before entering a state of sleep or sleep. Although similar meaning, but there are some different. Sleep is just keep the memory power, reserved memory data, close the hardware such as CPU, hard disk, will produce a certain quantity of heat, advantage is fast startup, defect is need a small amount of electricity. Dormancy is the current memory data saved to the hard disk to form a dormant file and memory size, and then close all hardware, also is shut down, the hibernation file directly into the next time you start memory boot, boot after the computer back to a dormant state, such as you sleep, programs and files did not shut down, boot program and the file remains open.
You may have noticed, if the laptop is entering sleep mode, and put in the backpack, heat spread out inside the package, will make the computer body temperature increased a lot, for a long time high temperature will have very adverse effect on the notebook hardware.
Conclusion: laptop heat dissipation is not allow to ignore, if the fuselage overheating, light harm the laptop hardware, or battery explosion caused personal injury. How to simply determine whether laptop heat dissipation is good, can withstand the test? In fact this is not a difficult task: usually, the location of the outlet is the highest temperature area, warm touch feeling, with the hand touching the keyboard operation area, feeling cool palm rest position, shows the fuselage heat dissipation effect is excellent.
