大多数电脑玩家都知道,在安装CPU散热器之前,需要在CPU和散热器底座之间均匀地涂抹一层薄薄的导热硅脂,这样才能获得更好转载自电脑百事网的导热效果。而且电脑在使用比较长一段时间,在清理灰尘时需要检查一下硅脂是否干掉,一般需要重新涂抹,以提升CPU散热能力。转载自电脑百事网转载自电脑百事网转载自电脑百事网转载自电脑百事网转载自电脑百事网那么,CPU和散热器之间为和要涂抹硅脂呢?散热辅料除了硅脂还有其他的什么东西吗?今天我们就来给新手玩家们做个科普。转载自电脑百事网转载自电脑百事网转载自电脑百事网硅脂用来填充空隙,减小处理器和散热器之间的热阻转载自电脑百事网转载自电脑百事网转载自电脑百事网硅脂只需要均匀地涂抹薄薄的一层即可,太多太少都会影响散热效果,详见:【CPU怎么涂硅脂散热最好?CPU涂抹硅脂方法对比】转载自电脑百事网。转载自电脑百事网转载自电脑百事网我们知道,处理器的顶盖和散热器的底部都是金属材质(一般是铜或者铝合金),而且就算制造工艺再怎么完美,也不能能保证它们的表面绝对平整光滑,这就会使得两者直接接触时会留下微小的缝隙,另外,玩家如果在安装散热器的时候扣具没有安装平整,也会导致散热器底部翘边,出现缝隙(很小的缝隙可能影响还不大,如果散热器底座歪得厉害就得重新安装了)。正是因为有这些缝隙存在,处理器和散热器底座之间就会有少量空气,而空气会严重影响导热效率。因此,我们需要用一种填充物来填充这些缝隙,而硅脂则是性价比和适用性最好的选择。不过,千万不要认为硅脂涂得越多越好,其实硅脂的热传导系数(W/m·K,也可称之为导热系数)为0.8~8之间,和铜377的热传导系数相比差距悬殊,所以它真的就只能用来填充空隙,涂太多了反而是散热的累赘。

First of all, let us briefly understand what is CITE2019 Expo: CITE2019 (full name 2019 7th China Electronic Information Expo) (CITE Poster Introduction) Introduction Time: April 9-11, 2019 Venue: Shenzhen Convention and Exhibition Center Scale: 105,000 square meters Mi CITE2019 is striving to become "industry-leading, Asia's first, world-class" and has great international influence, bringing together smart home, smart hardware, virtual reality, sensors and the Internet of Things, artificial
Thermal resistance, the English name is thermal resistance, that is, the hindering effect of objects on heat conduction. The concept of thermal resistance is very similar to that of resistance, and the unit is also similar - °C/W, that is, the temperature difference between the two ends of the heat conduction path when the continuous heat transfer power of the object is 1W. In the case of a heat sink, the two ends of the heat conduction path are the heating object (such as the CPU, etc.) and the ambient air. Heat sink thermal resistance = (heating object temperature - ambient temperature) ÷ thermal conductivity. The thermal resistance of the heat sink is obviously the lower the better
In this article, I will introduce the most important part of the air-cooled radiator - the heat sink. Function: The heat sink is responsible for the mission of dissipating the heat generated by the heating object to the surrounding air, and is the heat conduction channel in the air-cooled radiator. Its main functions are three: 1. Endothermic - absorb the heat of a heating object with a small volume and a small area, so that its temperature will not rise sharply due to heat accumulation, resulting in various undesired consequences; 2. Heat conduction - heat absorbed
There are really countless CPU coolers on the market at present. Not only are old radiator manufacturers producing products, but many new brands enter the market every year. Although the radiators all look the same, and most people will not buy several different products in the same price range to compare, many people will easily buy a radiator with insufficient performance. Of course, in many cases, the load capacity of the radiator far exceeds the calorific value of the CPU, but it is not cost-effective to buy.
Not long ago, we tested four water-cooled radiators. The prices range from 300 yuan to entry-level water cooling to high-end water cooling of more than 800 yuan. The test results may be beyond the expectations of many players. The performance gap of water-cooled radiators is not as obvious as the price. This review sparked a lot of discussion among netizens, and inevitably touched on another controversy-whether the computer is reprinted from the computer Pepsi network, is it better to be water-cooled or air-cooled? This issue is not debated
