技术领域
本发明属于太阳能利用技术领域，特别是一种蜂窝型流道双面吹胀式PVT组件。
背景技术
太阳能是世界上最大的、利用最广的可再生能源，与其他能源相比较，它具有能量巨大、使用无污染等优点，开发利用太阳能以及提高能源利用率成为太阳能利用领域的热点问题。在该领域，主要的技术为太阳能光伏技术和太阳能光热技术，其中太阳能光伏技术是通过光伏效应将光能转换成电能加以利用；太阳能光热技术是将太阳能收集并转换成热能加以利用。但太阳能光伏技术将部分太阳能转换为光伏余热而散失到环境中，造成了太阳能的浪费，此外，光伏板在阳光长时间照射后，温度升高，发电效率下降，并且高温还会损伤光伏板致使其寿命减少；而太阳能光热技术在太阳能向热能转换过程中，由于太阳能和热能之间品味差较大，光热转换过程不可逆损失较大。

所述的铝制吹胀式换热板1，其流道是蜂窝型，增大内部循环工质的湍流度，提高了吸热能力，较大程度地降低了光伏电池片的温度，进一步提高了光伏电池片的电效率。
所述的铝制吹胀式换热板1是双面吹胀，增大了换热流道内循环工质的质量流量，提高了热能输出能力；
所述的黑色光伏背板，用于吸收太阳热能以及防止光伏电池片漏电；
所述的光伏电池片组件，由汇流带串接起来，利用太阳能光生伏特效应将光能转换为电能；
所述的光伏电池片组件，单个光伏电池片的类型包括单晶硅、多晶硅、非晶硅等；
所述的钢化玻璃板，用于保护光伏电池片、减少组件与空气的对流换热损失。
本发明的有益效果：
本发明对太阳能的光和热进行利用，能源利用率高；
本发明可作为热泵系统的蒸发器，为太阳能热泵工程的应用提高基础换热组件；
本发明中的蜂窝型流道强化了组件的换热能力；
