Description

TECHNICAL FIELD

[0002] Building integrated photovoltaics (BIPV, Building Intergrated PV, PV is Photoboltaic) is a technology that integrates solar power generation (photovoltaic) products into buildings, which is a new concept of applying solar power generation. Simply put, it is to install solar photovoltaic power arrays on the building envelope to provide power, such as photovoltaic building roofs, photovoltaic curtain walls, and photovoltaic daylight roofs. The photovoltaic building roof on the market is mainly composed of color steel tiles and photovoltaic modules. In order to meet the load-bearing requirements of color steel tiles, the contact surface of the color steel tile and the photovoltaic module is usually made into a horizontal and close structure. However, this arrangement prevents the color steel tile and the photovoltaic module from forming a heat dissipation space, causing the temperature of the photovoltaic module to gradually rise during power generation, and the heat cannot be dissipated, which will affect the power generation efficiency of the photovoltaic module over a long period of time.

[0003] Therefore, the utility model discloses a photovoltaic building roof, the photovoltaic building roof, including color steel tile and photovoltaic module, color steel tile includes tile body, is equipped with support plane and heat dissipation space on tile body, support plane is used for supporting photovoltaic module, heat dissipation space is equipped with heat dissipation device, through heat dissipation device can accelerate the diffusion of heat between photovoltaic module and color steel tile, reduce the temperature between photovoltaic module and color steel tile, thereby improve the photovoltaic efficiency of photovoltaic module.

[0004] However, in the above-mentioned photovoltaic building roof, when the heat dissipation device adopts a water cooling pipeline, it needs to be laid along the length of the heat dissipation space (the heat dissipation space is composed of the tile body of the color steel tile and the support plane below the tile body), which requires additional pipeline laying, causing the installation process to be complicated and increasing the workload of workers. After the pipeline is laid, the heat needs to be transferred through the tile body and the pipe wall of the pipeline during heat exchange, i.e., the heat needs to be transferred through two layers of medium, resulting in low cooling efficiency and affecting the power generation efficiency of the photovoltaic module.

[0047] The cooling liquid used in the application is generally water, and can also be other heat exchange medium. In addition, it should be noted that the inlet and outlet are arranged on the two converter shells, and there are two cases, one of which is that the inlet is arranged on one of the converter shells, and the outlet is arranged on the other converter shell, and the other is that the inlet and outlet are arranged on only one of the converter shells, and the other converter shell is not provided with the inlet and outlet, and the specific case is determined according to the number of changes of the cooling liquid flow direction in the serpentine heat exchange channel.

[0048] In the application, the number of photovoltaic modules 300 in the photovoltaic mechanism is three, which are sequentially sealed and connected along the width direction of the color steel tile 200, so as to reduce the spacing between adjacent photovoltaic modules 300, thereby facilitating the saving of laying space.

In this way, the cooling liquid flows along the serpentine heat exchange channel, and finally is discharged from the outlet. During the flow process, the cooling liquid absorbs the heat of the photovoltaic module 300 above through the color steel tile 200, thereby achieving the effect of cooling the photovoltaic module 300 and improving the power generation efficiency of the photovoltaic module 300.

[0055] Specifically, as shown in Figures 6-9 、 Figure 15 and Figure 16 , the valve rod 110 is a circular shaft, and the upper notch 901 and the lower notch 801 are semicircular arc-shaped through grooves. When assembling the heat exchange shell, first, place the lower sealing block 800 in the bottom of the shell 400 (the number of lower sealing blocks 800 in the present application is eight, which is determined according to the number of heat exchange channels, and the number of lower sealing blocks 800 is always less than the number of heat exchange channels by one), each lower sealing block 800 is located after the adjacent exchange port 401, then place the valve rod 110, so that the two ends of the valve rod 110 are in contact with the inner walls at the two ends of the shell 400, and the circumferential outer edge of the lower part of the valve rod 110 is in contact with the inner wall of the upper notch 801 of the lower sealing block 800, and each lower sealing block 800 is located between the two limiting convex rings 111 to prevent the lower sealing block 800 from shifting in the length direction of the valve rod 110, then according to the shape of the serpentine heat exchange flow channel, select the corresponding lower sealing block 800 to place the upper sealing block 900, so that the inner wall of the upper notch 901 of the upper sealing block 900 is in sealing contact with the upper part of the circumferential outer edge of the valve rod 110, and the upper sealing block 900 is located between the two limiting convex rings 111 to prevent the upper sealing block 900 from shifting in the axial direction of the valve rod 110, at this time, the upper sealing block 900 and the lower sealing block 800 directly below it form a valve block 600, and the position part of the lower sealing block 800 above which the upper sealing block 900 is not laid does not form a valve block 600, after covering the shell cover 500, the exchange cavity is formed between the adjacent two valve blocks 600 (i.e. the position part of the lower sealing block 800 above which the upper sealing block 900 is not laid), which is used to connect the adjacent two heat exchange channels.

Among the four pipes 120, two pipes 120 are detachably connected with sealing plugs 130, and the other two pipes 120 form an inlet and an outlet, respectively.

[0058] Specifically, as shown in Figure 2 、 Figures 13-16 By providing two pipes 120 on the shell body 400 of the two heat exchange shells, the shapes of the four pipes 120 are the same. During assembly, according to the actual situation, two of the four pipes 120 can be plugged by the sealing plugs 130. The pipes 120 are threadedly connected with the sealing plugs 130, and of course other detachable connection modes can also be selected. The remaining two pipes 120 form an inlet and an outlet, respectively.
