中空玻璃隔熱性能比較好應(yīng)該是很多人都知道的一個(gè)道理，但是原理你知道嗎？雙組份打膠機(jī)廠家提示大家，想要明白這個(gè)道理，要清楚中空玻璃的能量傳遞方式，下面我們一起看一下詳細(xì)的介紹！
It should be a truth that many people know that insulating performance of hollow glass is better, but do you know the principle? The manufacturer of two-component glue beater reminds you that in order to understand this truth, first of all, we need to know the way of energy transmission of hollow glass. Now let's take a look at the detailed introduction!
中空玻璃的能量傳遞有三種方式：即輻射傳遞、對(duì)流傳遞和傳導(dǎo)傳遞。
There are three ways of energy transfer in hollow glass: radiation transfer, convection transfer and conduction transfer.
1、輻射傳遞
1. Radiation transfer
輻射傳遞是能量通過射線以輻射的形式進(jìn)行的傳遞，這種射線包括可見光、紅外線和紫外線等的輻射，就象太陽光線的傳遞一樣。合理配置的中空玻璃和合理的中空玻璃間隔層厚度，可以大限度的降低能量通過輻射形式的傳遞，從而降低能量的損失。
Radiation transfer is the transfer of energy in the form of radiation through radiation, which includes visible, infrared and ultraviolet radiation, just like the transmission of solar light. Reasonable arrangement of insulating glass and reasonable thickness of insulating glass spacer can minimize energy transfer through radiation form, thus reducing energy loss.
2、對(duì)流傳遞
2. Convection transmission
對(duì)流傳遞是由于在玻璃的兩側(cè)具有溫度差，造成空氣在冷的一面下降而在熱的一面上升，產(chǎn)生空氣的對(duì)流，而造成能量的流失。造成這種現(xiàn)象的原因有幾個(gè)：一是玻璃與周邊的框架系統(tǒng)的密封不良，造成窗框內(nèi)外的氣體能夠直接進(jìn)行交換產(chǎn)生對(duì)流，導(dǎo)致能量的損失;二是中空玻璃的內(nèi)部空間結(jié)構(gòu)設(shè)計(jì)的不合理，導(dǎo)致中空玻璃內(nèi)部的氣體因溫度差的作用產(chǎn)生對(duì)流，帶動(dòng)能量進(jìn)行交換，從而產(chǎn)生能量的流失;三是構(gòu)成整個(gè)系統(tǒng)的窗的內(nèi)外溫度差較大，致使中空玻璃內(nèi)外的溫度差也較大，空氣借助冷輻射和熱傳導(dǎo)的作用，在中空玻璃的兩側(cè)產(chǎn)生對(duì)流，然后通過中空玻璃整體傳遞過去，形成能量的流失。合理的中空玻璃設(shè)計(jì)，可以降低氣體的對(duì)流，從而降低能量的對(duì)流損失。
Convection transfer is due to the temperature difference on both sides of the glass, which causes the air to drop on the cold side and rise on the hot side, resulting in air convection and energy loss. There are several reasons for this phenomenon: one is the poor sealing between glass and surrounding frame system, which results in the direct exchange of gas inside and outside the window frame, resulting in convection, resulting in energy loss; the other is the unreasonable design of the interior space structure of the hollow glass, resulting in the effect of temperature difference in the interior gas of the hollow glass. The third is that the temperature difference between the inside and outside of the windows constituting the whole system is large, which results in the temperature difference between the inside and outside of the hollow glass. With the help of cold radiation and heat conduction, air convection first occurs on both sides of the hollow glass, and then it is transmitted through the hollow glass as a whole. In the past, energy was lost. Reasonable design of hollow glass can reduce the convection of gas and reduce the convection loss of energy.
3、傳導(dǎo)傳遞傳
3. Conduction and transmission
導(dǎo)傳遞是通過物體分子的運(yùn)動(dòng)，帶動(dòng)能量進(jìn)行運(yùn)動(dòng)，而達(dá)到傳遞的目的，就象用鐵鍋?zhàn)黠埡陀秒娎予F焊東西一樣，而中空玻璃對(duì)能量的傳導(dǎo)傳遞是通過玻璃和其內(nèi)部的空氣來完成的。我們知道，玻璃的導(dǎo)熱系數(shù)是0.77W/ mk。而空氣的導(dǎo)熱系數(shù)是0.028 W/ mk，由此可見，玻璃的熱傳導(dǎo)率是空氣的27倍，而空氣中的水分子等活性分子的存在，是影響中空玻璃能量的傳導(dǎo)傳遞和對(duì)流傳遞性能的主要因素，因而提高中空玻璃的密封性能，是提高中空玻璃隔熱性能的重要因素。
Conduction transfer is the movement of molecule, which drives energy to move, and achieves the purpose of transmission, just like cooking with iron pot and soldering with electric iron, while the transmission of energy by hollow glass is accomplished through glass and air inside it. We know that the thermal conductivity of glass is 0.77W/mk. The thermal conductivity of air is 0.028 W/mk. It can be seen that the thermal conductivity of glass is 27 times of that of air, and the presence of active molecules such as water molecules in air is the main factor affecting the energy transmission and convection transmission of hollow glass. Therefore, improving the sealing performance of hollow glass is to improve the heat insulation of hollow glass. An important factor in performance.
