Hot summer days, many notebooks began to transform hand warmers, especially students who hid in the bedroom playing games every day, no air conditioning at all overwhelmed. We touch briefly on thermal design for notebook and laptop cooling techniques.
First of all, to talk about the notebook what thermal design, that is to say what kind of design can enhance the notebook cooling.
Tube: similar to the CPU and heat sink, notebook cooling by heat pipe, heat transfer to the fans at the (of course, also has a passive cooling of notebook, like the new Macbook). Since notebook needs are light, heat also made flat.
Other materials used and quantities other than mentioned before, of heat pipe in notebook layout, length, weight, greatly affect the cooling performance of notebook.
Layout test tube manufacturers in the design of the motherboard power, CPU and graphics card should be generally close to the cooling fan, heat quickly stretched to the cooling fan, should not be in the Middle near the heating elements such as memory, hard disk.
A pipe like this throughout the CPU and graphics design in a number of low prices will appear. This picture of laptops strung together two large fever, and then next to the memory, I am afraid, is to make artificial small Sun.
The length of the pipe should be as short as possible, it tube too long will result in low efficiency. Shorten the distance between pipe length to CPU fan on the one hand, on the other hand is a reserve position in board design, allowing tube to straight to the fan, a straight line between two points short. After the notebook apart there is a tube that winds like a snake inside, almost frenzied.
Like the pipe across the Pacific, return several small islands in the middle of heating, presumably for melting glaciers as a force.
The thickness of the pipe it is to say, in the case of the same thickness, thicker pipe with strong thermal capacity. The other hand, thicker pipe is guaranteed with the CPU and the fan with a larger contact area.
Fans: focuses on the number of fans here. Save for reasons of cost or is not doing design, some manufacturers are promoting a single show with only a fan, for mainstream gaming graphics card, is clearly not enough. Du said at the beginning of the game, dual fans three fans are even necessary. Separate CPU and video card cooling fan, can have better cooling effect.
Thermal dissipation space: mainly is the gap between the motherboard and the body. Greater thermal dissipation space can guarantee the smooth ducts, but also to sacrifice the thickness, so the game does a slim is not entirely a good thing. Look at Alienware heavy body to know that not only accommodates a wide range of high-performance hardware, and also provides a large space for heat dissipation.
Of course, also have the courage to challenge humans in the world, just performance hardware thin fuselage. Welcome, as long as the heat sink clearance, thin is even better.
Ventilation: ventilation holes into the wind, and the wind window, the theory is, the more the bigger the better. Of course, the ventilation holes not only into the wind, but also into the dust, dust control measures did not do so, ventilation holes once more, computer wall slightly.
Broad sense as long as they can access wind gap should be called the cooling vents, so it includes keyboard key gaps. Some products use the keyboard for the longitudinal thermal to achieve unexpected results.
Channel: vertical duct different from desktop, laptop thin fuselage duct design more dimensional, so as to enhance heat dissipation. In General, will take the plane into the wind at the end of the game, side and top air duct design, this is why you play the d face has a line of fresh air inlet.
Duct design and desktop is similar to portable duct should also follow the principles of wind to blow. Airflow should be continuous and orderly on one side and, on the other side. Some portable duct design chaos, wind blowing around, say no more.
Low density of cold air from the bottom into the controversial, do not consume too much of the location. Some scrupulous manufacturers will by means of joining stepping pad d ensure air inlet open. virtual reality iPhone case
By opening the hinge of the top fuselage design such as this are subtle, although I think a little ugly. Of course, there are also some notebooks in order to make integration of d, gave up the bottom air inlet, and moved to a different location, d is a complete plane, looks more beautiful.
Instead of blowing out hot air from the top side and trouble spots, because cooling vents requires no small locations, the most serious is the side of the connector. For this reason, many manufacturers are under the much elsewhere in the notebook holes, such as the previously mentioned keyboard slot. Such as high-end game common in the rear of the wind:
There are lunatic at the hinge of the wind, on a very tall:
Mac is that you like to do. But hinge out of the wind generally blows the screen, resulting in an increase in the temperature of the screen, is a hazard for high performance laptop.
There is a display of wind, such as Surface Book:
Oh yes, Surface Book there are both screen the wind shaft wind. Of course, the price of the wind is going to screen the screen can have some space for heat dissipation, so the thickness of the screen must be increased. VR iPhone case
Desktops duct often worry about how, heat, after all, space is very large, picked a radiator has a very powerful. Portable duct design is very important, notebooks, small spaces can lead to heat is out, other than the CPU and graphics card, hard drive and memory are computer generated heat, heat and they can only be fulfilled by the air flow in the duct.
Body material: this is something that many people tend to neglect, metal, plastics, fibers and other materials of the thermal effects are not the same fuselage material to some extent will affect the overall thermal performance of notebook. In theory, the metallic cooling effect should be better, but at the same time, heat to the metal after the hand is also very hot.
Heat source: duct design, no matter how good, there will be a very hot place, that is the source location. If you roll the beat, QWER found four fingers cooked, then prove you bought before the book did not make reference to the heating source. Heat source can be adjusted through the duct and motherboard designs, suggest that, particularly in a game before you buy, look it up on the Internet.
Of course, the heat source no matter how stressed that only in one point c, often meet, choice is not too critical.
Laptop cooling capacity will affect hardware run also greatly affects the experience of notebook, keyboard and trackpad are, after all, on top of the heat source. A really good laptop, not just performance screen, while at the same time there should be a good experience.
If you have bought books, then there is no way, heat capacity was already doomed. But don’t lose heart, enhanced cooling techniques below may be able to help you.
Tube modification: heat part of the transformation, the simple thing to replace the grease, I here will say such a silly thing about it! So I picked one found online:
Water cooling notebook modified asks are you afraid! Heat transformation can be said to be the most interesting notebook DIY way, in addition to changing water so horrible, you can also consider tubular heating elements, heat adaptation, finning and other means.
Openings for reform:
Cheapest air duct reconstruction is ash. Why is the cheapest, because of yourself you can do, take apart laptop and wiped, and then loaded on. Before you buy a notebook, look at the notebook did d simple cleaning Windows, lift the lid wipe it.
Of course, don’t need cleaning too frequently, generally one or two years at a time, the desktop is the same. Some CPU was murmur to higher than yesterday, and I don’t know what to say … …
Laptop-assisted radiator is another weapon, many students may have bought. Laptop-assisted radiator can be roughly divided into notebook cooling base and stroke type radiator.
Laptop cooling base is common, that is a shell of the fan. On one hand, the wind blows, the equivalent of air into the notebook on the other, elevate the d side of the notebook, makes it easier for air to enter.
This seemingly simple notebook cooling base, conspiracy and heavy, you may want to see before you buy:
Note d (that is, bottom) air inlet is not, buy it basically useless. Notebook Cooling base principle is to give d air inlet air supply, even the air inlet is not, is basically nonsense;
Location is not on the air inlet of the fan, bought basically useless. Buy when the pick is good;
Air pressure is not enough, is not to buy. Before testing, really saw notebook cooling base temperature rise. Notebook Cooling base of those more than 10 dollars, are really less the air conditioning more fierce.
Exhaust thermal artifact type radiator is recognized, through powerful for taking the notebook’s heat reach the cooling effect.
But it cannot be denied that certain ventilation radiator is a very low price of chicken. Exhaust radiators also have compatibility problems, but rubber ring seal product has become popular, a big problem. But also a few of the most serious problems of noise, a little with thousands of fans in the ears, really very ventilation.
Don’t forget, if you side not cooling vents, you can also go, contents of the ventilation is not so good.
About duct, another point to remind the notebook keyboard membrane. Mentioned some products through the keyboard slot heat sink, if you buy a rubber keypad membrane covered, the equivalent of road, blocking the wind, of course, is very bad. If you are obsessive-compulsive, or love sloppy often chips off soda sprinkled on the keyboard on the keyboard, you can consider buying a breathable fabric or nylon membrane keyboard.
Remove the external solution, you may wish to see a power settings in the Control Panel, you can set your computer’s power supply mode, slightly downwards, to a certain extent reduce the heat of CPU and graphics card.
The other hand, notebook fever is normal. Desktop may have a fever, but you don’t touch it so I can’t feel it. Fever is a normal phenomenon, not to be so nervous. If you stand there are forty or fifty degrees, it really had to be alert to … …
