Speaker network manufacturer: how to solve the problem of computer speakers?
In people's lives, computers have become a necessity in people's lives. Computers are still a necessity in work, and the problem of computer radiators is always a problem for many people. So, how can we reform or transform a better radiator? This is the topic of this issue.
The radiator itself is a cooling tool. While producing the bluetooth speaker net, the heat dissipation process and results are considered. For notebooks, more attention is paid to the use of radiators. If the computer does not have a radiator, it will not work, and the notebook Without a radiator, the motherboard or CPU will be burned out, and radiators are required for both electronic products and computer products. When the radiator appears to be unable to work, it must be destined to fail to operate quickly.
We designed the radiator to be smaller and more powerful, and the fan is also used, but the current radiator uses hydraulic crystals to cool the motherboard or CPU, not a task that can be completed by ordinary fans. Just like the speaker nets on the outside of some notebooks, hydraulic water dedicated to radiators will be used to cool down!
Under the action of external force, when two objects are in close contact, they will produce relative motion or a tendency of relative motion, and the contact surface will generate resistance to block this motion. This phenomenon is called friction. The frictional force with relative motion is called static friction, and the magnitude of static friction varies with the magnitude of the external force acting on the object. When the external force overcomes the most. Static friction is strong, and friction that produces relative motion between objects is called kinetic friction. According to the different motion forms of two relative moving objects, kinetic friction can be divided into sliding friction and rolling friction. according to. The state of friction, that is, surface contact and oil film thickness, can be divided into four categories of sliding friction, namely dry friction, boundary friction (boundary lubrication), fluid friction (fluid lubrication) and mixed friction (mixed lubrication).
(1) Dry friction
Dry friction occurs when pure metal contacts two friction surfaces without any lubricant or protective film. Of course, the production of punching mesh is also to dry friction punch the steel plate through the punching machine. In engineering practice, there is no real dry friction, because any part of the surface exposed to the atmosphere will not only form an oxide film due to oxidation, but also be more or less "contaminated" by lubricating oil or moisture. At this time, the friction coefficient of the friction system will be significantly reduced. In mechanical design, friction without significant lubrication is usually considered dry friction.
(2) Boundary friction
A thin boundary film is attached to each of the two friction surfaces, and the two surfaces are still in the friction state of convex peak contact, which is called boundary friction. Compared with dry friction, the friction state of boundary friction has been greatly improved, and the degree of friction and wear depends on the properties of the boundary film, the mechanical properties of the material surface, and the surface morphology.
(3) Fluid friction
The two friction surfaces are completely separated by a layer of fluid (liquid or gas), and the friction where the convex peaks on the surfaces do not directly contact is called fluid friction. Fluid friction does not wear the metal surface, which is an ideal friction state.
(4) Mixed friction
The state of dry friction, boundary friction, and fluid friction between two surfaces is called mixed friction.
