下面将结合本发明创造实施例中的附图，对本发明创造实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明创造一部分实施例，而不是全部的实施例。基于本发明创造中的实施例，本领域普通技术人员在没有付出创造性劳动的前提下所获得的所有其他实施例，都属于本发明创造保护的范围。
本发明创造的目的是提供一种具有滤光功能的隔热温差测试装置，以解决上述现有技术存在的问题，实现对不同波长光线的过滤，并提高隔热温差测试的准确度。
为使本发明创造的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发明创造作进一步详细的说明。
如图1至图3所示：本实施例提供了一种具有滤光功能的隔热温差测试装置100，包括箱体14，箱体14内设置有旋转灯盘6和测试舱。
驱动装置能够驱动旋转灯盘6旋转，旋转灯盘6上设置有多个辐照光源7。在本实施例中，驱动装置包括驱动电机1和减速箱2，驱动电机1的输出轴与减速箱2的输入轴固连，减速箱2的输出轴与螺杆20的一端固连，旋转灯盘6上固定设置有调节螺母21，调节螺母21与螺杆20螺纹连接，螺杆20与旋转轴同轴，通过手动转动旋转灯盘6来调整调节螺母21在螺杆20螺纹连接的高度位置，能够实现对旋转灯盘6高度的调节，以调整辐照光源7与待测试板件11的垂直距离，进而调节待测试板件11上表面获得的光照能量。箱体14上还设置有用于控制驱动电机1的转速控制器15，旋转灯盘6的转速和高度皆能实现既定范围内的连续可调。需要说明的是，旋转灯盘6是匀速缓慢旋转的，故转动的螺杆20通过调节螺母21带动旋转灯盘6旋转时，由于调节螺母21与螺杆20之间的摩擦力的存在，调节螺母21与螺杆20之间并不会发生相对转动，从而保证装置能够稳定工作。
通过设置旋转灯盘6使得辐照光源7能够旋转，从而使得照射在每个子测试舱9中的光照能量相等，控制了光照能量这一不稳定变量，使得待测试板件11的表面的温度均相等，从而提高了隔热温差测试的准确度。
测试舱包括两个以旋转灯盘6的旋转轴为轴周向排列的子测试舱9，即旋转灯盘6的旋转轴位于两个子测试舱9之间，且每个子测试舱9的大小相等，以保证旋转灯盘6旋转时，照射到每个子测试舱9中的光照能量相等。相邻的两个子测试舱9通过保温隔板10相隔，测试舱靠近辐照光源7的一侧设置有滤光片8，辐照光源7发出的光经滤光片8滤光后照射到测试舱，测试舱和保温隔板10分别与滤光片8密封连接；在本实施例中，滤光片8采用石英玻璃，滤光片8也可以采用其它材质，通过滤光片8对入射光线进行滤光，从而滤去不必要的波长，通过选择不同种类的滤光片8能够实现对不同光照环境的模拟；在有不滤光的需求时也可以直接去掉滤光片8。
每个子测试舱9中均设置有第一温度传感器16、待测试板件11和第二温度传感器12，待测试板件11的四周通过硅胶密封圈18与子测试舱9的内壁密封连接，且待测试板件11垂直于旋转轴，待测试板件11位于第一温度传感器16和第二温度传感器12之间；两个待测试板片与辐照光源7的距离相等。测试舱上设置有能够开启和关闭的物料门19，以便于放置和更换待测试板件11。一个子测试舱9中的待测试板件11为对比试件，另一个子测试舱9中的待测试板件11上涂覆有待测试的涂料，作为待测试件。
子测试舱9中还设置有位于待测试板件11远离辐照光源7的一侧的金属支撑片13，金属支撑片13的四周与子测试舱9的内壁密封连接，金属支撑片13通过导热硅脂与待测试板件11紧密粘合；第二温度传感器12设置在金属支撑片13远离待测试板件11的一侧。于本实施例中，金属支撑片13采用铝片。导热硅脂具有优异的导热性、电绝缘性、化学稳定性，填充了铝板和待测试板件11间的空隙，实现了热量的顺畅迅速传导，极大提高了测试精度。
箱体14上还设置有箱体温度传感器17、若干个控温风扇3和用于控制控温风扇3的箱体温度控制器5，箱体温度传感器17与箱体温度控制器5信号连接，且箱体温度控制器5具有温度显示功能，控温风扇3位于测试舱外，在本实施例中，控温风扇3共有四个，对称分布于箱体14顶部的四个角，且全部朝向箱体14内部，主要用来促进箱体14上部空气流动，避免温度过高，从而快速调节箱内温度、提高工作效率。
箱体14的四壁和底板上均布置有保温材料，箱体14上设置有门，门能够开启和关闭，便于维修设备和更换辐照光源7。
箱体14上设置有与子测试舱9一一对应的温度显示器4，温度显示器4用于显示对应的子测试舱9中的第一温度传感器16和第二温度传感器12所检测到的温度。
本实施例具有滤光功能的隔热温差测试装置100的具体使用方法如下：
在本实施例中将一个子测试舱9中的第一温度传感器16称为第一上温度传感器、第一下温度传感器，将另一个子测试舱9中的第一温度传感器16称为第二上温度传感器、第二下温度传感器；
将待测试件放入一个子测试舱9内，将对比试件放入另一个子测试舱9内，然后放置滤光片8，放置好滤光片8后，测试舱即形成独立、密闭的空间，并被保温隔板10均分为两个独立的子测试舱9，通过驱动电机1驱动旋转灯盘6旋转，并打开辐照光源7，使得辐照光源7的光线均匀射入两个子测试舱9内，由于辐照光线完全均匀，两个子测试舱9中获得了同等的光照能量，故待测试件和对比试件的上表面应具有同样温度，即第一上温度传感器和第二上温度传感器应捕捉并显示相同的数值，同时体现出与箱体温度传感器17之间的差值，直观地反映滤光片8的滤光性能。第一下温度传感器和第二下温度传感器分别捕捉待测试件和对比试件背面的温度，第一上温度传感器与第一下温度传感器的差值、第二上温度传感器与第二下温度传感器的差值能直观地反映建筑隔热涂料或保温隔热材料的隔热性能，即温度差值越大、材料的绝热效果越好。
