你有用水冷幫電腦降溫嗎?(水冷討論區)

specific heat capacity 係 based on material

根本水既chemical nature冇變 點降低heat capacity

可能我phy太廢

加入左冷卻濟就已經唔係純水啦
明唔明姐 就係加入左冷卻濟落去令到混合物既熱容量低左

e=mc︿t
e=能量...m=質量...c=比熱容量..︿t=溫度
如果水既質量不變..能量不變..但熱容量低左..自然溫度就高左(姐係水內溫度)
自然水既導熱性高左...水冷既效能就因此又提高左

I see no point that thermal conductivity is related to specific heat capacity. Can you explain it further? Just make a guess do you mean that after cooling agent is added, the dipole moment (as well as hydrogen bonding)linking OH- and H+ are disturbed, increasing the mobility of continuously ionized H2O molecule? or a larger temperature difference providing better condition for convection?

只係mixture of coolant & water
但in fact , water既chemical nature doesnt change .
都係咁多水都係要咁多energy

水冷唔普及都係因為成效唔大

同樣價錢出個風冷仲勁過水冷

我都同意以位人兄既講法,,,
買個4xx蚊...即勁風扇...吹...仲勁過水冷,,,
所以...有錢買水冷...不如買好d..cpu同地板

純銅同有雜質既銅2者傳熱效能你應該知邊個勁啦
同樣道理,純水係4200比熱溶
加左其他野冇理由再多假= =?

唉...佢講極都唔明咖-____________-
算啦...係咁係度講化學..但佢又唔明白混合物既化學性質同物理性質...依兩樣野都分唔開就唔洗同佢地講啦/_\

我物理得熱學,"電磁學,原子物理學"ok-.-"...."未來= =
不過d力同加速度就死得-.-
話時話,有冇野仲高過水?(比熱溶)

︿t應該係 2個溫度既差,唔係溫度A_A

有,水唔係最高,不過唔知咩物質-.-上堂無講

CAN U SURE THAT THE C OF UR COOLANT USED IS SO MUCH LOWER THAN WATER

CHECK IT OUT IN WIKI

IT PROVES THAT COOLANT ALSO HAS A HIGH HEAT CAPACITY

可能我真係太廢

but i am sure that if urs is an even distribution of heat
there is no use lowering the C

kyva1929

lol, why am I ignored?

I repeat. I see no point that thermal conductivity is related to specific heat capacity. Can you explain it further?

even in view of only CE level, water as a coolant was mainly due to its high specific heat capacity, as well as high specific latent heat of vaporization.

but not to lower its heat capacity so as to enhance thermal conductivity<--also, I see no reason for stating that.

it is not the case . Thermal conductivity  mainly depends on the structure (how the particles are arranged)
of the material

it was supposed to be the mobility of electrons , ions, or a molecule. bonding type, electronegativity of composed atom, ion, the dipole moment considering a molecule as a whole etc...

導熱性好似係屬於物理性質...完全唔關化學事喎...

可唔可介紹一下風冷 比小小資料or圖片看看

wow what a great reason to persuade us to type in chinese !
