Description

Technical Field

[0001] This utility model relates to the field of solar thermal heating technology, and in particular to an air-type blower manifold. Background Technology

[0002] Solar thermal heating is highly valuable for widespread adoption due to its high heat conversion efficiency and low operating costs. Currently, air-based solar thermal systems typically consist of a solar collector (composed of a double-pass vacuum collector tube, headers, and support structure), insulated ductwork, a water-air heat exchanger (which transfers heat from the air to the water for storage and use), a circulating fan, a hot water pump (which drives the water to circulate between the water-air heat exchanger and the water tank), and a control system. When sunlight shines on the double-pass vacuum collector tube, the air inside is heated and flows upwards along the tube driven by the circulating fan. It then converges in the upper header and flows horizontally out, entering the water-air heat exchanger through the insulated ductwork. Finally, it flows back into the lower header through the insulated ductwork, and then circulates back into the double-pass vacuum collector tube for repeated heating. The air circulation in this process is driven by the circulating fan on the insulated ductwork.

[0003] In the aforementioned solar collector system, the circulating fan, as an independent component, increases the difficulty of on-site equipment layout and installation. At the same time, the circulating fan requires an independent insulated enclosure, resulting in higher manufacturing and transportation costs. Utility Model Content

[0004] The purpose of this invention is to provide an air-type blower manifold to solve the problems and defects mentioned in the background art.

[0005] To achieve the above objectives, the following technical solution is provided:

[0006] An air-type blower header includes a header shell, on which equally spaced circular holes for inserting heat collection tubes are provided on the side wall. Duct interfaces are provided at both ends of the header shell. A DC fan is installed at each end of the inner cavity of the header shell. A solar photovoltaic panel is fixedly connected to the top of the header shell, and the solar photovoltaic panel is electrically connected to the DC fan.

[0007] Furthermore, the manifold housing includes an insulated shell and insulated end caps disposed at both ends of the insulated shell. The insulated shell and the insulated end caps are fixedly connected by screws. The solar photovoltaic panel is fixedly connected to the insulated shell. The circular hole is opened on the insulated shell. The duct interface is opened on the insulated end cap.

[0008] Preferably, an annular boss is provided on the end face of the insulation shell, and an annular groove corresponding to the annular boss is provided on the inner side of the insulation end cap. The cooperation between the annular boss and the annular groove can increase the sealing performance of the mounting surface.

[0009] Preferably, the insulation end cover is provided with a rivet nut, the DC fan is fixed to the insulation end cover by an internal hex screw, the internal hex screw is threadedly connected to the rivet nut, and an asbestos sealing gasket is provided between the DC fan and the insulation end cover.

[0010] The DC fan is fixed to the detachable insulated end cover by threaded connection of hexagonal screws and rivet nuts, ensuring that the DC fan can be easily disassembled and assembled; an asbestos sealing gasket is placed between the DC fan and the insulated end cover to keep the gas on both sides of the DC fan isolated and prevent air leakage and pressure loss in the manifold housing cavity.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] This invention integrates the lower header, DC fan, and solar photovoltaic panels in an air-type solar thermal collector system, reducing the number of components in the system and significantly lowering the production and transportation costs.

Detailed Implementation

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0022] like Figures 1 to 6 As shown, an air-type blower header includes a header housing 1, a DC fan 2 installed at each end of the inner cavity of the header housing 1, and two solar photovoltaic panels 3 installed on the top of the header housing 1. The DC fan 2 and the solar photovoltaic panels 3 are electrically connected.

[0023] The manifold outer shell 1 is composed of an insulated shell 11 and an insulated end cap 12. The insulated shell 11 is a rectangular composite insulated barrel with open ends. Several circular holes 111 are equidistantly provided on the side wall of the insulated shell 11 for inserting the heat collection tube 02. An insulated end cap 12 is installed at each end of the insulated shell 11. The insulated shell 11 and the insulated end cap 12 are fixedly connected by flat-head screws 5. The contact surface between the insulated shell 11 and the insulated end cap 12 is not flat. An annular boss 112 is provided on the end face of the insulated shell 11. An annular groove 122 is provided on the inner side of the insulated end cap 12, which corresponds to and cooperates with the annular boss 112. The cooperation between the annular boss 112 and the annular groove 122 can increase the sealing of the installation surface.

[0024] The insulation end cap 12 has a duct interface 121 in the middle, which is used to connect an external insulation duct 10.

[0025] Each insulation end cap 12 has four rivet nuts 4 installed on its inner side for installing the DC fan 2. The DC fan 2 is fixed to the insulation end cap 12 by hexagon socket screws 6. The hexagon socket screws 6 are threadedly connected to the rivet nuts 4. At the same time, an asbestos sealing gasket 7 is also placed between the DC fan 2 and the insulation end cap 12 to keep the gas on both sides of the DC fan 2 isolated and prevent air leakage and pressure loss.

[0026] Similarly, eight rivet nuts 4 are installed on the top surface of the insulation shell 11 for installing the solar photovoltaic panel 3. There are two solar photovoltaic panels 3, located on the left and right sides of the top of the insulation shell 11 respectively. Each solar photovoltaic panel 3 includes a photovoltaic panel body 31, and each photovoltaic panel body 31 is fixed to the top surface of the insulation shell 11 by four hexagonal socket screws 6, which are threadedly connected to the rivet nuts 4. A junction box 32 is located at the bottom of the photovoltaic panel body 31, and the junction box 32 is connected to the DC fan 2 via silicone wires 33. The silicone wires 33 enter the insulation shell 11 through small holes and connect to the DC fan 2, thus preventing the silicone wires 33 from being exposed to outdoor sunlight. To ensure the sealing of the small holes at the top of the insulation shell 11, sealant should be applied when threading the silicone wires 33.

[0027] Explanation of the working principle of this utility model:

[0028] like Figure 7 As shown, the air-type blower header 01 of this utility model is installed in an air-type heat collection system. The air-type heat collection system includes a heat collection pipe 02, with both ends of the heat collection pipe 02 inserted into the air-type blower header 01 and the heat exchange header 03, respectively. At the same time, the two ends of the air-type blower header 01 and the heat exchange header 03 are connected by two insulated air ducts 04. The DC fan 2 in the air-type blower header 01 drives the air in the insulated air ducts 04 on both sides of the air-type blower header 01 to be compressed into the air-type blower header, and then flows upward through the heat collection pipe 02 to the heat exchange header 03. Finally, it flows back to the two insulated air ducts 04 through both ends of the heat exchange header 03, forming a complete heat collection air circulation.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
