as buy several chassis radiator, installed in the chassis out of the air or into the air can be, in fact, this is wrong, the installation of chassis fan also need to master skills, the technique here is refers to--chassis air duct. about what is the air duct, the wind tunnel to the computer chassis heat impact, you may wish to read under: 　　Internal structure of the chassis and knowledge of the distributi

The final solution is: the reason why "origin to origin" fails to be selected when the document is linked is that the coordinate system is not correct. The problem is as follows: I want to set

the application of a lot of process variable control parameters, the application of pressure sensing elements are more, mainly using the deformation of the object under pressure, the corresponding electrical parameter changes to measure the pressure parameters. Our sensors use ceramic resistors to measure process pressure and are relatively short in relative measurement time.The pressure measurement object is mainly liquid, gas, the measured variable is the corresponding medium pressure, and th

to achieve a good cooling effect. It is well known that the traditional power supply chassis due to the upper cluster power supply, CPU and CPU power supply 3 parts of the large heat. Therefore, according to the physical law of rising hot air, the fan on the power supply, in addition to cooling itself, also inhaled the CPU and power to bring a lot of heat. No matter whether the power supply or the CPU Halo can not be a reasonable shunt cooling. The power supply is placed to solve this problem.

A period of time to participate in the invitation of the "Fairy duct" in beta. Pick 25 questions a day. Below is a week later, "Fairy duct" The second time I invited me, I wrote to their letter. I've been in the game for more than a year, and I don't want to get deeper ... "Fairy duct" does need to improve. However, according to the General game development cyc

become a steamer, not to mention good heat dissipation. Therefore, the chassis fan is also very important. many friends in the installed box fan has a misunderstanding: only the wind, not into the wind, the chassis other places are also very strict design, difficult to enter the wind. This can seriously affect the air duct inside the chassis. (tutorial) The duct is the trajectory of the air in the chas

disk when it is not considered this, or the chassis does not have enough space to install, the two hard drives installed to a very close position, so that the heat dissipation of the hard disk is quite unfavorable. The cooling duct of the chassis should pay attention to: In many cases, the heat inside the chassis if not effectively excluded, then all the PC accessories temperature will rise, naturally also includes the hard drive. So the design of t

into three categories, one is the air volume fan, the other is the wind fan, the last one is all balanced fan, the three kinds of fans as the name suggests is some of the air volume is particularly large, some wind pressure is particularly large, some of them are a bit but not small (are very large or very expensive or noisy), and then according to the actual needs of the It should be said that the wind fan is suitable for most applications, allowing more air to participate in the heat exchang

ah?" The colon quipped, "Perl's various magic characters are like a pair of sharp scissors, do the work of text clipping and so on. This is its biggest advantage, originally Perl is wall used to do UNIX system management, later on CGI's extensive application also benefited from this. This also gives Perl a very strong adhesion, so there's a ' tape on the Internet (Duct tape) [2] ' saying. It is also known as the Swiss Army knife, concise and complex,

Liquid cooling radiatorLiquid heat dissipation includes water cooling and oil cooling, which are generally water-cooled.The water-cooled radiator has the following advantages:1. higher heat dissipation efficiency.The general working principle of the water-cooled radiator is: using the ultra-high specific heat capacity of the water, coupled with the rapid push of the water pump, the CPU (or other heat source) heat is taken away, pushed t

To choose the overall heat dissipation of a good chassis, first of all to note the size of the chassis, especially the size of its internal space. According to manufacturing standards, according to the expansion of the chassis performance and shape, chassis can be divided into ultra-thin, half high, 3/4 high, full height and vertical, horizontal chassis. The common standard ATX vertical chassis on the market is 3/4 high and full high chassis, this chassis has three or three or more 5.25-inch dri

Many novice users in the installation of the tower heat sink will be entangled in the radiator and fan orientation problem, the Internet consulted a lot of users. ▲ a tower radiator with a back blow is a common installation method In most cases, the radiator fin duct is located in front and back direction, the fan in front of the wind, but also t
