为什么中空玻璃的隔热功能如此突出?

中空玻璃隔热性能比较好应该是很多人都知道的一个道理░,但是原理你知道吗?双组份打胶机厂家提示大家░,想要明白这个道理░,首先要清楚中空玻璃的能量传递方式░,下面我们一起看一下详细的介绍!
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!
中空玻璃的能量传递有三种方式:即辐射传递•●、对流传递和传导传递。
There are three ways of energy transfer in hollow glass: radiation transfer, convection transfer and conduction transfer.
1•●、辐射传递
1. Radiation transfer
辐射传递是能量通过射线以辐射的形式进行的传递░,这种射线包括可见光•●、红外线和紫外线等的辐射░,就象太阳光线的传递一样。合理配置的中空玻璃和合理的中空玻璃间隔层厚度░,可以大限度的降低能量通过辐射形式的传递░,从而降低能量的损失。
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•●、对流传递
2. Convection transmission
对流传递是由于在玻璃的两侧具有温度差░,造成空气在冷的一面下降而在热的一面上升░,产生空气的对流░,而造成能量的流失。造成这种现象的原因有几个:一是玻璃与周边的框架系统的密封不良░,造成窗框内外的气体能够直接进行交换产生对流░,导致能量的损失;二是中空玻璃的内部空间结构设计的不合理░,导致中空玻璃内部的气体因温度差的作用产生对流░,带动能量进行交换░,从而产生能量的流失;三是构成整个系统的窗的内外温度差较大░,致使中空玻璃内外的温度差也较大░,空气借助冷辐射和热传导的作用░,首先在中空玻璃的两侧产生对流░,然后通过中空玻璃整体传递过去░,形成能量的流失。合理的中空玻璃设计░,可以降低气体的对流░,从而降低能量的对流损失。
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•●、传导传递传
3. Conduction and transmission
导传递是通过物体分子的运动░,带动能量进行运动░,而达到传递的目的░,就象用铁锅作饭和用电烙铁焊东西一样░,而中空玻璃对能量的传导传递是通过玻璃和其内部的空气来完成的。我们知道░,玻璃的导热系数是0.77W/ mk。而空气的导热系数是0.028 W/ mk░,由此可见░,玻璃的热传导率是空气的27倍░,而空气中的水分子等活性分子的存在░,是影响中空玻璃能量的传导传递和对流传递性能的主要因素░,因而提高中空玻璃的密封性能░,是提高中空玻璃隔热性能的重要因素。
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.
