近年来，轻薄化成为笔电发展的一大趋势，在产品数量和销量都处于快速上升的状态。然而，在一些对于笔电性能要求非常高的消费者眼中，轻薄本却不是他们的最优选择。原因是如果要做到极致轻薄，笔电往往会在散热、电池容量等方面做一些让步，进而影响到笔电处理器的选用、续航、性能释放等。
如何实现轻薄本性能、散热和续航的均衡，是一个难题。而在散热方面，无风扇设计就是一个尝试的方向，联想、DELL、HP、APPLE、微软、华为等主流笔电品牌都有相关产品推出。

无风扇设计可以有以下几个好处：
0噪音；
可实现轻薄化设计；
内部空间可以放入更大容量的电池、内存等，提升续航；
密封性好，减少灰尘对笔电性能的影响.
但是就目前的技术来说，无风扇散热设计基本上都是采用低功耗处理器，在性能上是会打折扣的。要做出高性能的无风扇设计笔电，还需要等待技术的进一步发展。而在2021年德国iF设计奖概念类获奖作品中，就有一款15W高功耗下不会降频或过热的无风扇设计笔电，下面我们来看一下。
英业达无风扇笔记本电脑
据德国iF官网图片信息显示：
Two years of breakthrough to present this world's best fanless laptop. Inventec made it 4 times more powerful than any other laptop on the market. This completely silent laptop adapts to any server environment by reducing 30 equipment failure rate and increasing 125% battery life. The absolute fanless system provides a quieter environment with zero anxiety possibility and much more flexibility for internal component placement。
这是Inventec经过两年的突破，推出了这款世界上最好的无风扇笔记本电脑，使它的功能比市场上任何其他笔记本电脑都强大4倍。这款完全静音的笔记本电脑可降低30台设备故障率，延长125%的电池续航时间，适用于任何服务器环境。无风扇系统提供了一个更安静的环境，具有零焦虑的可能性和更大的灵活性。
In each generation of intel U Series CPU, the full power TDP (Thermal Design Power) is in general set at 15W. In order to do that, the thermal module for traditional fanless laptops is Usually installed in the base of the laptop and dispense its heat to the surface;therefore, the thermal performance is limited to its chamber size and causes the throttling of the CPU due to its inefficiency to cool down surface temperature, which is why none of them has been able to reach TDP 15W.
在每一代intel U系列CPU中，TDP（Thermal Design Power，热设计功耗）通常设置为15W。为了做到这一点，传统无风扇笔记本电脑的散热模块通常安装在笔记本电脑的底座上，并将其热量分配到表面；因此，热性能受限于其腔室尺寸，并且由于其冷却表面温度的效率低而导致CPU的节流，这就是为什么它们都不能达到TDP 15W的原因。
Inventec's unique fanless design overcomes the dficulties of putting 2 joint heat pipes that go through hinge caps to the back of the display, We managed to make the heat pipes move conjunctly with the hinge, so it can dispatch heat to the back of the display while assuring its durability
This innovative solution is the key technology to the worlds first and only fanless laptops that can reach 15W TDP without throttling or overheating
Inventec独特的无风扇设计，将两个穿过铰链盖的连接热管放在显示器背面的困难，我们设法使热管与铰链一起移动，因此它可以将热量输送到显示器背面，同时确保其耐用性
这种创新的解决方案是世界上第一款也是唯一一款无风扇笔记本电脑的关键技术，可以让笔电达到15W TDP，而不会降频或过热。
unique heat pipe design
inventec solution conducts heat from chassis with a special thermal module placed through hinge cap and dispatches heat to a cover
英业达的解决方案是采用独特的热管设计，通过一个铰链盖放置的特殊热模块从底盘传导热量，并将热量分配到A面。
hinge durability surpasses top 5 market brands standards
the thermal hinge of inventec 15w fanless can last for over 30000 cycles
且inventec 15w无风扇笔电的铰链使用寿命超过30000次，耐久性超过前五大市场品牌标准。
surface temperature up to 3℃ lower than market general standard
同时，表面温度要低与市场标准约3℃。
英业达无风扇设计笔电有以下几个优点：
-
Zero Fan Noise
Fan noise that lasts for long period of time can cause dizziness, headache, tinnitus, inadvertence, and lower working efficienc
-
风扇噪音为零
风机噪声持续时间长，会引起头晕、头痛、耳鸣、心不在焉，降低工作效率；
2. Carefree
Since there is no venting hole, Users no longer have to worry about blocking them and it can also prevent the external substance from getting into the chasis and protect the internals from different factors in severe environment
2.防护性好
由于没有通风孔，使用者不用再担心堵塞，还可以防止外部物质进入底盘，在恶劣环境下保护内部不受各种因素的影响。
3. Better Durability
According to Inventec's big data of 30 years of experiences in notebook. we conclude that the fanless design will have a 30% lower failure rate
3.更好的耐用性
根据Inventec在笔记本领域30年经验的大数据。我们的结论是，无风扇设计的故障率将降低30%
