*還在用山寨版的改裝嗎?

*Modified version of the cottage still use it?

*貨車冷氣風扇與專用水箱電子風扇的差別~如何區分?

爲甚麼冷氣風扇不可以當水箱風扇使用?

Air-conditioning fan and water tank trucks dedicated fan of the difference between electronic, how to distinguish?
Why air conditioning fan can not use the fan when the water tank?

1.風壓不足:

一般冷氣散熱片厚度約1.5~2 cm
多數車種水箱厚度加上冷氣散熱片，厚度多在10 cm以上，需要較高的風壓克服。

1. Air pressure less than:

General air-conditioning heat sink thickness of about 1.5 ~ 2 cm
Most vehicles with air-conditioning heat sink radiator thickness, the thickness of more than 10 cm or more, require higher pressure to overcome.

2.耐溫不足~零件易老化故障

 一般冷氣散熱排風溫度多在50度以下
 水箱散熱排風溫度高達100度以上

3.葉片單薄、易斷裂

葉片多為細長條型 ，容易因震動、熱疲勞而斷裂。

3. blade thin, easily broken

Leaves mostly slender bar, susceptible to vibration, thermal fatigue and fracture.

4.亂流、噪音大 、浪費動力

葉片與集風罩沒有經過"流場最佳化設計"，亂流與風切聲交雜，浪費動力=浪費錢。

4 turbulence, noise, waste power

Cover and set the wind vane has not been "optimized design flow", turbulence and wind noise are mixed, a waste of power = waste of money.

5.異念科技改裝的 BMW 車系

 直接使用原廠電腦訊號

不需要切水管接三通

  更省油
  完整度更高

5. "Imagination Science & Technology" modified BMW cars

Directly to the computer using the original signal

Do not cut the water pipe connection tee

More fuel-efficient

Complete a higher degree

以下為三種失敗的整流罩案例
沒有經過流場動向考量容易照成局部過熱/產生亂流/噪音

有人標榜集風罩使用鋁製的因為鋁散熱最好~乍聽之下好像有道理  導熱效果鋁>不繡鋼>朔鋼

但是實務上是錯誤的集風罩好壞關鍵是在形狀~讓氣流能夠平均的作用在水箱上

集風罩製作最大的禁忌就是有直角的地方~容易照成局部過熱/產生亂流/噪音

水箱的關鍵才是材質


 

不是黑色浪管就是防火套管~用打火機燒就知道!

雙B 的價值被一個800元的風扇完全搞砸~這不是雙B該有的"品味"











但事實上

Fairing without consideration of flow trends, likely to cause overheating, resulting in turbulence and noise.
