具体实施方式 detailed description
下面结合附图给出本实用新型较佳实施例，以详细说明本实用新型的技术方案。 The preferred embodiments of the utility model are given below in conjunction with the accompanying drawings to describe the technical solution of the utility model in detail.
本实施例由玻璃盖板1，蜂窝吸热体2，保温材料层3，底板4，进气流道5，出气流道6和空气流道7组成，蜂窝吸热体2下部贴附保温材料层3，保温材料层3下部为底板4，蜂窝吸热体2上部为玻璃盖板1，空气流道7位于蜂窝吸热体2与玻璃盖板1之间，空气流道7两端连接有进气流道5和出气流道6，蜂窝吸热体2和保温材料层3位于玻璃盖板1、底板4、进气流道5及出气流道6构成的空气平板集热器箱体内，所述玻璃盖板1为单层玻璃，所述蜂窝吸热体2表面设有选择性吸热涂层。 This embodiment is composed of a glass cover plate 1, a honeycomb heat absorber 2, an insulating material layer 3, a bottom plate 4, an air inlet channel 5, an outlet air channel 6 and an air flow channel 7, and the lower part of the honeycomb heat absorber 2 is attached with an insulating material layer 3. The lower part of the insulation material layer 3 is the bottom plate 4, the upper part of the honeycomb heat absorber 2 is the glass cover plate 1, the air flow channel 7 is located between the honeycomb heat absorber 2 and the glass cover plate 1, and the two ends of the air flow channel 7 are connected with inlet The air channel 5 and the air outlet channel 6, the honeycomb heat absorber 2 and the thermal insulation material layer 3 are located in the air flat collector box formed by the glass cover plate 1, the bottom plate 4, the air inlet channel 5 and the air outlet channel 6, and the glass The cover plate 1 is single-layer glass, and the surface of the honeycomb heat absorbing body 2 is provided with a selective heat absorbing coating.
太阳辐射透过玻璃盖板1到达蜂窝吸热体2，蜂窝吸热体2的蜂窝状孔结构高效地吸收太阳辐射，冷空气从进气流道5进入空气流道7，蜂窝吸热体2以辐射和对流换热的形式将吸收的热量传递给冷空气，冷空气在流过空气流道7后被加热成为热空气，从出气流道6流出空气平板集热器。 The solar radiation reaches the honeycomb heat absorber 2 through the glass cover plate 1. The honeycomb hole structure of the honeycomb heat absorber 2 absorbs solar radiation efficiently, and the cold air enters the air flow channel 7 from the air inlet channel 5. The form of radiation and convective heat transfer transfers the absorbed heat to the cold air, and the cold air is heated to become hot air after flowing through the air flow channel 7, and flows out of the air flat plate heat collector from the outlet flow channel 6.
蜂窝吸热体2具有蜂窝状多孔结构，蜂窝吸热体2贴附在下部的保温材料层3上，蜂窝吸热体2和保温材料层3复合在底板4和玻璃盖板1中形成高温空气集热器，太阳辐照到达蜂窝吸热体2后进入蜂窝状多孔结构内，形成多重反射增加吸收率。该蜂窝状孔结构也同时抑制了空气自然对流热损失，以及增加角系数修正因子，增加太阳能空气集热器的吸收透过因子。 The honeycomb heat absorber 2 has a honeycomb porous structure, and the honeycomb heat absorber 2 is attached to the lower insulation material layer 3, and the honeycomb heat absorber 2 and the heat insulation material layer 3 are combined in the bottom plate 4 and the glass cover plate 1 to form high-temperature air In the heat collector, the solar radiation enters the honeycomb porous structure after reaching the honeycomb heat absorber 2, forming multiple reflections to increase the absorption rate. The honeycomb pore structure also suppresses the natural convection heat loss of the air at the same time, and increases the correction factor of the view coefficient to increase the absorption and transmission factor of the solar air heat collector.
太阳能空气集热器内部的蜂窝吸热体为带有选择性吸热涂层的蜂窝状多孔结构，且蜂窝状孔的一端开口，另外一端封闭，这种结构可以使太阳辐射在蜂窝状孔内部形成多重反射，增加太阳辐射吸收率的同时抑制了空气自然对流热损失，以及增加角系数修正因子，增加太阳能空气集热器的吸收/透过因子，并且蜂窝状多孔结构增加了平板吸热体表面的宏观粗糙度，强化了表面湍流强度，增加了流道内的对流换热系数。 The honeycomb heat absorber inside the solar air collector is a honeycomb porous structure with a selective heat-absorbing coating, and one end of the honeycomb hole is open, and the other end is closed. This structure can make the solar radiation inside the honeycomb hole Form multiple reflections, increase the solar radiation absorption rate while suppressing the natural convection heat loss of the air, and increase the angle coefficient correction factor, increase the absorption/transmission factor of the solar air collector, and the honeycomb porous structure increases the flat heat absorber The macroscopic roughness of the surface strengthens the surface turbulence intensity and increases the convective heat transfer coefficient in the flow channel.
