The utility model discloses a square tube solar heat collector. The feature of the collector is that the heat-absorbing coating is directly coated on the surface of the heat-absorbing pipe, so that the water flow absorbs heat faster and the heat loss is lower. The heat absorbing part of the collector is composed of several heat absorbing tubes. The cross-section of the heat-absorbing pipe is rectangular, and the side of the pipe facing the sun is coated with a heat-absorbing coating. When working, cold water enters the heat collector from the water inlet pipe, and then flows into each heat-absorbing pipe. The heat-absorbing coating on the surface of the heat-absorbing pipe absorbs sunlight and heats up, heating the water in the pipe. The hot water flows into the outlet pipe and finally into the water storage tank.
Description
一、技术领域 1. Technical field
本实用新型涉及太阳能热利用领域，特指一种方管型太阳能集热器。The utility model relates to the field of solar heat utilization, in particular to a square tube solar heat collector.
二、背景技术 2. Background technology
太阳能热水器是一种利用太阳能做为能源加热水或传热介质的太阳能利用装置。现有的太阳能热水器产品中以真空管型太阳能热水器和平板型太阳能热水器最具有代表性。真空管集热器吸热部件为真空管，热损失小。与真空管型太阳能热水器相比，平板型太阳能热水器具有结构简单、阳光拦截面积大、密封要求低、不需防冻、工质便宜、响应快等优点。但也存在热损失大、集热效率低等缺点。如何进一步提高太阳能热水器的集热效率，一直是科研人员追求的目标。A solar water heater is a solar energy utilization device that uses solar energy as an energy source to heat water or a heat transfer medium. Among the existing solar water heater products, vacuum tube solar water heaters and flat plate solar water heaters are the most representative. The heat-absorbing part of the vacuum tube collector is a vacuum tube, and the heat loss is small. Compared with vacuum tube solar water heaters, flat plate solar water heaters have the advantages of simple structure, large sunlight interception area, low sealing requirements, no antifreeze, cheap working medium, and fast response. However, there are also disadvantages such as large heat loss and low heat collection efficiency. How to further improve the heat collection efficiency of solar water heaters has always been the goal pursued by researchers.
平板型太阳能热水器主要由透明盖板、吸热板、水管、保温壳体四部分组成。工作时，涂有选择性吸收涂层的吸热板将太阳辐射转化为热能，热量通过导热传给水管中流动的水。走水管子与吸热板之间的组合方式多为焊接，两者之间的热阻以及总体几何结构对集热器效率有很大影响。The flat-panel solar water heater is mainly composed of four parts: a transparent cover plate, a heat-absorbing plate, a water pipe, and an insulating shell. When working, the heat absorbing plate coated with selective absorbing coating converts solar radiation into heat energy, and the heat is transferred to the water flowing in the water pipe through heat conduction. The combination of the water pipe and the heat absorbing plate is mostly welding, and the thermal resistance between the two and the overall geometric structure have a great influence on the efficiency of the collector.
针对平板型太阳能热水器的上述问题，已有若干种改进措施：例如专利“真空平板式太阳能热水器”(专利申请号200620023546.X)，其特征是贮水箱直接作为换热水箱，贮水箱上盖作为换热板，通过平板玻璃真空集热，通过减少管路和真空隔热减少热损失。又如专利“一种平板太阳能热水器”(专利申请号00263980.7)，将透明盖板设计成双层玻璃夹真空层的盖板，减少热损失。Aiming at the above-mentioned problems of flat-plate solar water heaters, several improvement measures have been taken: for example, the patent "vacuum flat-plate solar water heater" (patent application number 200620023546. Heat exchange plate, vacuum heat collection through flat glass, reduces heat loss by reducing pipelines and vacuum insulation. Another example is the patent "a kind of flat solar water heater" (patent application number 00263980.7), in which the transparent cover is designed as a cover with a vacuum layer sandwiched between double-layer glass to reduce heat loss.
上述专利实施都对提高太阳能集热器的热效率有一定的效果，但由于需使用双层盖板，降低了日光的透射比增加了集热器重量，不利于同建筑结合。The implementation of the above patents has a certain effect on improving the thermal efficiency of the solar collector, but due to the need to use double-layer cover plates, the transmittance of sunlight is reduced and the weight of the collector is increased, which is not conducive to the integration with the building.
三、发明内容 3. Contents of the invention
本实用新型提出的目的在于改进已有技术的不足，提供一种走水管子与集热板结合充分，传热效率高，安装方便的太阳能热水器。The purpose of the utility model is to improve the deficiencies of the prior art, and provide a solar water heater with sufficient combination of the water pipe and the heat collecting plate, high heat transfer efficiency and convenient installation.
为实现上述目的，本实用新型采用如下技术方案：In order to achieve the above object, the utility model adopts the following technical solutions:
方管型太阳能集热器由进水管、吸热管、保温壳体、出水管、透明盖板、吸热涂层等组成，其特征是：冷水由进水管分流入吸热管；集热器的若干吸热管截面为矩形，向阳一面镀有吸热涂层，工作时吸热涂层吸收日光升温，加热吸热管中的水。热水汇流入出水管。The square-tube solar collector is composed of water inlet pipe, heat-absorbing pipe, heat-insulating shell, outlet pipe, transparent cover plate, heat-absorbing coating, etc. It is characterized by: the cold water flows into the heat-absorbing pipe from the water inlet pipe; Some of the heat-absorbing tubes have a rectangular cross-section, and the sunny side is coated with a heat-absorbing coating. During work, the heat-absorbing coating absorbs sunlight and heats up to heat the water in the heat-absorbing tubes. Hot water flows into the outlet pipe.
本实用新型使传统的太阳能热水器得到两项改进：一是使吸热板与走水管子结合为一体，使导热效率提高；二是消除了由于焊接部位受热变形导致的水管开焊问题。The utility model makes two improvements to the traditional solar water heater: one is to integrate the heat-absorbing plate and the water pipe to improve the heat conduction efficiency;
