Description

一种增加金属翅片的储能型太阳平板集热器 An energy storage type solar flat collector with added metal fins

技术领域 technical field

本发明涉及太阳能的技术领域，尤其涉及能够储存能量的太阳能集热器装置的技术领域。The invention relates to the technical field of solar energy, in particular to the technical field of a solar thermal collector device capable of storing energy.

背景技术 Background technique

相变材料的储热技术在空调、太阳能行业和建筑节能被广泛的推广应用，主要是内因其具有优良的储热性能。将相变材料与平板集热器结合不需要额外的储热水箱。不仅可以满足建筑一体化的要求，同时还能实现能量的持续供应以及供水的温度恒定。The heat storage technology of phase change materials has been widely promoted and applied in the air conditioner, solar energy industry and building energy saving, mainly because of its excellent heat storage performance. Combining phase change materials with flat plate collectors does not require additional storage tanks. It can not only meet the requirements of building integration, but also realize the continuous supply of energy and the constant temperature of the water supply.

但是目前现有的有机物相变材料所固有的特点是热导率小，传热太慢，导致储能效果差，同时储能效率低。特别是太阳辐射的间断性和不连续性以及相变材料热导率低的问题，相变储能的速度非常低。However, the inherent characteristics of the existing organic phase change materials are low thermal conductivity and slow heat transfer, resulting in poor energy storage effect and low energy storage efficiency. Especially the discontinuity and discontinuity of solar radiation and the low thermal conductivity of phase change materials, the speed of phase change energy storage is very low.

发明内容 Contents of the invention

本发明目的是提供一种储能效果好、储能效率高、能够有效提高相变储能速度的增加金属翅片的储能型太阳平板集热器。The object of the present invention is to provide an energy storage type solar panel heat collector with metal fins, which has good energy storage effect, high energy storage efficiency and can effectively increase the phase change energy storage speed.

本发明为实现上述目的，采用如下的技术方案：In order to achieve the above object, the present invention adopts the following technical solutions:

本发明包括透明材料层、相变材料层、吸热板、保温材料层、蛇形管、导热金属，吸热板设置在透明材料层的下方，相变材料层设置在吸热板的下方，透明材料层、相变材料层、吸热板的外周设置保温材料层，所述蛇形管和金属翅片分别设置在相变材料层内。The present invention comprises a transparent material layer, a phase-change material layer, a heat-absorbing plate, an insulating material layer, a serpentine tube, and a heat-conducting metal. The heat-absorbing plate is arranged under the transparent material layer, and the phase-change material layer is arranged under the heat-absorbing plate. The transparent material layer, the phase-change material layer, and the outer periphery of the heat-absorbing plate are provided with a thermal insulation material layer, and the serpentine tubes and metal fins are respectively provided in the phase-change material layer.

比较好的是：上述透明材料层为平板玻璃层。Preferably, the transparent material layer is a flat glass layer.

比较好的是：上述平板玻璃层为单层或双层平板玻璃层。More preferably: the above-mentioned flat glass layer is a single layer or double layer of flat glass layers.

比较好的是：上述吸热板上涂有选择性吸收涂层。Preferably, the above-mentioned heat absorbing plate is coated with a selective absorbing coating.

比较好的是：上述相变材料层为熔点高、相变潜热大的石蜡。Preferably, the phase change material layer is paraffin wax with high melting point and large phase change latent heat.

本发明采用上述技术方案，与现有技术相比具有如下的优点：The present invention adopts above-mentioned technical scheme, has following advantage compared with prior art:

1、随着建筑一体化概念的提出，平板集热器在与建筑的结合上优势明显优于真空管和热管，且能承重。同时平板集热器与相变材料的结合，可以实现能量的持续供应，还能省去传统的储热水箱，这不仅节约了用户的空间和费用，也更有利于建筑的美观。1. With the introduction of the concept of building integration, the advantages of flat plate collectors in combining with buildings are obviously superior to those of vacuum tubes and heat pipes, and they can bear loads. At the same time, the combination of flat plate collectors and phase change materials can achieve continuous energy supply and save the traditional hot water storage tank, which not only saves space and cost for users, but also is more conducive to the beauty of the building.

2、采用相变材料填充在平板集热器当中，利用潜热储能具有很大的储能能力以及在在相变储能和释放能量时，温度变化小，能实现稳定的储能和释放能特性。2. The use of phase change materials to fill in the flat plate collectors, the use of latent heat energy storage has a large energy storage capacity, and when the phase change energy is stored and released, the temperature change is small, and stable energy storage and release can be achieved characteristic.

3、但有机物相变材料(如石蜡等)所固有的特点是热导率小，传热太慢，在石蜡或其他相变材料中增加金属翅片不仅能够强化传热的效果，增大热传递的速率，还能在石蜡熔化过程中起到支撑集热器的作用，防止吸热板以及集热器的形变。3. However, the inherent characteristics of organic phase change materials (such as paraffin, etc.) are low thermal conductivity and slow heat transfer. Adding metal fins to paraffin or other phase change materials can not only enhance the heat transfer effect, but also increase the heat transfer efficiency. The speed of transmission can also play a role in supporting the heat collector during the paraffin melting process, preventing the deformation of the heat absorbing plate and the heat collector.

4、本发明解决了太阳辐射的间断性和不连续性以及相变材料热导率低的问题，有效提高了相变储能的速度，由于不需传统的水箱，为用户节约了空间和费用。4. The present invention solves the problems of discontinuity and discontinuity of solar radiation and low thermal conductivity of phase change materials, effectively improves the speed of phase change energy storage, and saves space and cost for users because no traditional water tank is needed .
