Description
技术领域technical field
本实用新型涉及一种太阳能热利用装置,具体涉及一种平板太阳能集热器。 The utility model relates to a solar heat utilization device, in particular to a flat solar heat collector. the
背景技术Background technique
目前,太阳能集热器主要有真空管太阳能集热器和平板太阳能集热器,其中平板太阳能集热器较美观并能更好的与建筑一体化。但缺点是其金属吸热板制造难度较大,造价较高!所以目前在我国不如真空管太阳能集热器那样普及。 At present, solar collectors mainly include vacuum tube solar collectors and flat solar collectors, among which flat solar collectors are more beautiful and can be better integrated with buildings. But the disadvantage is that its metal heat absorbing plate is more difficult to manufacture and the cost is higher! Therefore, it is not as popular as vacuum tube solar collectors in our country at present. the
发明内容Contents of the invention
本实用新型的目的在于针对平板太阳能集热器的上述问题,提供一种液体吸热式平板太阳能集热器,使用玻璃代替金属做成吸热板,板内深色液体直接吸收太阳光热量进行利用,这样不但利用玻璃代替昂贵的金属材料,而且省掉吸热涂层,达到简化制造工艺,降低成本之目的。 The purpose of this utility model is to solve the above-mentioned problems of flat solar collectors, and provide a liquid heat-absorbing flat solar collector, which uses glass instead of metal to make a heat-absorbing plate, and the dark liquid in the plate directly absorbs the heat of sunlight for heating. In this way, not only glass is used to replace expensive metal materials, but also heat-absorbing coatings are omitted, so as to simplify the manufacturing process and reduce costs. the
为达到上述目的,本实用新型的技术方案如下:一种液体吸热式平板太阳能集热器,包括吸热板、透明盖板、保温层、循环水泵、保温箱和换热器。吸热板流道出口通过换热器和循环水泵与保温水箱相连,流道进口直接与保温箱相连,吸热板由上下两片贴合在一起的玻璃板构成,其中至少有一片玻璃板上有截面为齿状的条纹,两片玻璃板贴合后条纹形成可供液体通行的流道。吸热板流道内有深色液体,另外在吸热板与透明盖板之间封闭有二氧化碳气体,利用二氧化碳导热系数比空气小且不能透过常温热辐射的特点,增强系统的保温效果。运行时循环水泵将吸热板流道内的深色液体(如墨水,已着色的防冻剂等)向保温箱内泵,使吸热板流道内形成负压并通过管道从保温箱内吸水,这样就形成了负压循环,这种负压循环可避免上下两块玻璃板被液体正压力撑开,为保证吸热板流道内的负压,保温箱的安装位置不可高于吸热板,且保温箱上开有排气孔,以保证保温箱不会形成高压对吸热板流道产生正压力。吸热板的另一种构造是用玻璃一体成形,吸热板由整块玻璃板构成,玻璃板内开设二排以上的液体流道,上下两排流道相互错开。这样既能保证利用到全面积的太阳光,又能保证玻璃吸热板的强度,还可承压运行。 In order to achieve the above object, the technical solution of the utility model is as follows: a liquid heat-absorbing flat-plate solar heat collector, including a heat-absorbing plate, a transparent cover plate, an insulating layer, a circulating water pump, an incubating box and a heat exchanger. The flow channel outlet of the heat absorbing plate is connected to the heat preservation water tank through the heat exchanger and the circulating water pump, and the flow channel inlet is directly connected to the heat preservation tank. There are stripes with a tooth-shaped cross section, and the stripes form a flow channel for liquid after the two glass plates are bonded together. There is a dark liquid in the flow channel of the heat absorbing plate, and carbon dioxide gas is sealed between the heat absorbing plate and the transparent cover plate. The heat preservation effect of the system is enhanced by utilizing the characteristics that the thermal conductivity of carbon dioxide is smaller than that of air and cannot pass through normal temperature heat radiation. During operation, the circulating water pump pumps the dark liquid (such as ink, colored antifreeze, etc.) in the flow channel of the heat absorbing plate into the incubator to form a negative pressure in the flow channel of the heat absorbing plate and absorb water from the incubating box through the pipeline, so that A negative pressure cycle is formed, which can prevent the upper and lower glass plates from being stretched by the positive pressure of the liquid. In order to ensure the negative pressure in the flow channel of the heat absorbing plate, the installation position of the incubator should not be higher than the heat absorbing plate, and There are vent holes on the incubator to ensure that the incubator will not form high pressure to generate positive pressure on the flow channel of the heat absorbing plate. Another structure of the heat-absorbing plate is integrally formed with glass. The heat-absorbing plate is composed of a whole glass plate. There are more than two rows of liquid flow channels in the glass plate, and the upper and lower rows of flow channels are staggered from each other. This can not only ensure the use of the full area of sunlight, but also ensure the strength of the glass heat-absorbing plate, and it can also operate under pressure. the
本实用新型的有益效果是,将传统的平板太阳能集热器利用金属表面涂层吸热改为玻璃流道内的深色液体吸热,这样省掉了昂贵的金属结构和涂层,达到简化制造工艺,降低成本之目的。 The beneficial effect of the utility model is that the traditional flat solar heat collector utilizes the heat absorption of the metal surface coating to absorb the heat of the dark liquid in the glass flow channel, thus saving expensive metal structures and coatings and achieving simplified manufacturing technology, the purpose of reducing costs. the

具体实施方式Detailed ways
在图1中,透明盖板(1)与保温层(5)之间是吸热板,吸热板由上玻璃板(2)和下玻璃板(4)贴合在一起构成,下玻璃板(4)上有截面为齿状的条纹,这样当上玻璃板(2)与下玻璃板(4)贴合后就形成了液体流道(3),流道(3)内充满深色液体如黑墨水,流道(3)出口通过换热器(6)和循环水泵(8)与保温箱(7)相连,流道(3)进口直接与保温箱(7)相连,保温箱(7)上开有排气孔(9),透明盖板(1)与吸热板之间充入二氧化碳气体。 In Fig. 1, there is a heat absorbing plate between the transparent cover plate (1) and the insulation layer (5), and the heat absorbing plate is composed of an upper glass plate (2) and a lower glass plate (4) bonded together, and the lower glass plate (4) There are stripes with a tooth-shaped cross section, so that when the upper glass plate (2) and the lower glass plate (4) are bonded together, a liquid flow channel (3) is formed, and the flow channel (3) is filled with dark liquid Such as black ink, the outlet of the flow channel (3) is connected to the incubator (7) through the heat exchanger (6) and the circulating water pump (8), the inlet of the flow channel (3) is directly connected to the incubator (7), and the incubator (7) ) has an exhaust hole (9), and carbon dioxide gas is charged between the transparent cover plate (1) and the heat absorbing plate. the
在有阳光时,阳光直接透过透明盖板(1)和上玻璃板(2)被流道(3)内的黑墨水吸收,同时启动循环水泵(8),从流道(3)吸水,往保温箱(7)内泵水,使吸热板内的流道(3)形成负压,由流道(3)进口从保温箱(7)内吸水,从而形成负压的深色液体循环,循环的深色液体在流经换热器(6)时将水加热以供利用。这种负压的深色液体循环不会对构成吸热板的上玻璃板(2)和下玻璃板(4)形成正压力使之胀开,如果由于其它原因,比如运行后保温箱(7)温度逐渐升高使箱内空气受热膨胀,压力升高时,排气孔(9)排气,保证使吸热板不会到正压破坏。 When there is sunlight, the sunlight directly passes through the transparent cover plate (1) and the upper glass plate (2) to be absorbed by the black ink in the flow channel (3), and at the same time start the circulating water pump (8) to absorb water from the flow channel (3), Pump water into the incubator (7) to form a negative pressure in the flow channel (3) in the heat-absorbing plate, and absorb water from the incubator (7) through the inlet of the flow channel (3), thereby forming a negative-pressure dark liquid circulation , the circulating dark liquid heats the water for use as it flows through the heat exchanger (6). This negative-pressure dark liquid circulation will not form positive pressure on the upper glass plate (2) and lower glass plate (4) forming the heat-absorbing plate to make it expand. ) The temperature gradually rises to make the air in the box thermally expand, and when the pressure rises, the exhaust hole (9) is exhausted to ensure that the heat-absorbing plate will not be damaged by positive pressure. the
图2是吸热板的另外一种构造,即是用玻璃一体成形的流道截面示意图,在图2中,一体成型玻璃吸热板(10)内开有一体成型流道(11),上下两排流道相互错开,这样既能保证利用到全面积的太阳光,又能保证玻璃吸热板的强度,还可承压运行。 Fig. 2 is another structure of the heat absorbing plate, which is a schematic cross-sectional view of a flow channel formed integrally with glass. In Fig. 2, an integrally formed flow channel (11) is opened in the integrally formed glass heat absorbing plate (10). The two rows of runners are staggered from each other, which can not only ensure the use of the full area of sunlight, but also ensure the strength of the glass heat-absorbing plate, and it can also operate under pressure. the
