Description
Technical Field
[0001] This disclosure relates to the field of photovoltaic technology, and more specifically, to a photovoltaic module. Background Technology
[0002] With the continuous development of solar photovoltaic power generation technology, the power and efficiency of photovoltaic modules are constantly improving, but this also brings the problem of high heat generation. On the one hand, excessively high temperatures can affect the power generation efficiency and lifespan of photovoltaic modules. On the other hand, to achieve higher power generation efficiency, related technologies require the use of support structures to adjust the photovoltaic panels to a specific tilt angle. However, the installation of support structures increases the structural complexity and cost of photovoltaic modules. Utility Model Content
[0003] The purpose of this disclosure is to provide a photovoltaic module to solve the technical problems existing in the related art.
[0004] To achieve the above objectives, this disclosure provides a photovoltaic module, comprising:
[0005] Photovoltaic panels;
[0006] A support plate is provided to support the photovoltaic panel. A cooling channel is formed inside the support plate, and an inlet and an outlet communicating with the cooling channel are formed on the side wall of the support plate.
[0007] A limiting protrusion is formed on two oppositely arranged sides of the support plate and extends upward to form a mounting groove with an opening at the top, which is used to accommodate a photovoltaic panel.
[0008] Heat dissipation fins are disposed on the lower end face of the photovoltaic panel, and the end of the heat dissipation fins facing away from the lower end face of the photovoltaic panel is formed as an inclined plane, so that the photovoltaic panel remains in an inclined state when the heat dissipation fins are in contact with the ground.
[0009] Optionally, there are multiple heat dissipation fins, which are spaced apart along the length or width of the support plate.
[0010] Optionally, the height of the heat dissipation fins gradually decreases along the direction from one end of the support plate to the other.
[0011] Optionally, each of the heat dissipation fins has an inclined plane formed at the end opposite to the support plate, and the multiple inclined planes formed by the multiple heat dissipation fins are arranged in the same plane.
[0012] Optionally, the photovoltaic module further includes a cooling fan for blowing airflow onto the heat dissipation fins.
[0013] Optionally, the gap between the cooling fan and the two adjacent cooling fins is arranged opposite to each other.
[0014] Optionally, the lower end face of the support plate includes a first region and a second region arranged adjacent to each other, the heat dissipation fins are disposed in the first region, and the heat dissipation fan is disposed in the second region.
[0015] Optionally, the liquid inlet and the liquid outlet are formed on the same side of the support plate.
[0016] Optionally, the cooling channel is composed of multiple straight segments and multiple curved segments. Along the length or width direction of the support plate, the multiple curved segments are arranged in parallel and spaced apart, and each of the curved segments is connected between every two adjacent straight segments.
[0017] Optionally, the limiting protrusion and the support plate are integrally formed.
[0018] Through the above technical solution, by setting cooling channels inside the support plate, the coolant can carry away the heat generated by the photovoltaic panel during the flow of the cooling channels, thereby achieving cooling and heat dissipation of the photovoltaic panel. At the same time, the heat dissipation fins set on the lower end face of the support plate absorb and transfer heat from the photovoltaic panel or the coolant during the heat dissipation process, thereby increasing the heat exchange area with the outside atmosphere and further improving the heat exchange effect.
[0019] Furthermore, since the end of the heat dissipation fins facing away from the lower end of the photovoltaic panel is formed as an inclined plane, when the photovoltaic module is placed on the ground, the inclined plane contacts the ground, thereby allowing the support plate and the photovoltaic panel mounted on the support plate to remain in an inclined state. There is no need to set up a support frame, which has the advantages of simple structure and convenient installation, and can reduce the production and installation costs of the photovoltaic module.
[0020] Furthermore, during the installation of the photovoltaic panel on the support plate, the limiting protrusions formed on the two oppositely arranged edges of the support plate and extending upward can limit and stop the photovoltaic panel from both ends, thereby enabling the installation and positioning of the photovoltaic panel without the need for fasteners. This further simplifies the installation process and achieves the goals of reducing installation costs and improving assembly efficiency.

Detailed Implementation
[0027] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0028] In this disclosure, unless otherwise stated, directional terms such as "up," "down," "left," and "right" are used to indicate orientation or positional relationships only for the convenience of describing this disclosure and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or a specific orientation structure and operation, and therefore should not be construed as a limitation of this disclosure. The terms "inner" and "outer" refer to the inner and outer contours of the corresponding structures.
[0029] Additionally, for "length direction" and "width direction", please refer to [link / reference]. Figure 1 The length and width directions are shown. It should also be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Furthermore, in the description referring to the accompanying drawings, the same reference numerals in different drawings denote the same elements.
[0030] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.
[0031] The tilt angle of a photovoltaic (PV) panel, also known as the installation tilt angle, refers to the angle between the PV panel and the horizontal plane. The choice of this angle directly affects the amount of solar radiation energy received by the PV panel, thus impacting its power generation efficiency. The ideal tilt angle should allow the PV panel to receive the maximum amount of direct sunlight throughout the year, rather than oblique sunlight.
[0032] Based on this, refer to Figures 1 to 2 As shown, this disclosure provides a photovoltaic module 1, including a photovoltaic panel 10, a support plate 20, a limiting protrusion 30, and heat dissipation fins 40. The support plate 20 is used to support the photovoltaic panel 10. A cooling channel 21 is formed inside the support plate 20. An inlet 23 and an outlet 24 communicating with the cooling channel 21 are formed on the side wall of the support plate 20. The limiting protrusion 30 is formed on two oppositely arranged sides of the support plate 20 and extends upward to form a mounting groove 22 with an opening at the top, together with the upper end surface of the support plate 20. The mounting groove 22 is used to accommodate the photovoltaic panel 10. The heat dissipation fins 40 are disposed on the lower end surface of the photovoltaic panel 10, and the end of the heat dissipation fins 40 away from the lower end surface of the photovoltaic panel 10 is formed as an inclined plane 41 so that the photovoltaic panel 10 remains in an inclined state when the heat dissipation fins 40 are in contact with the ground.
[0033] Through the above technical solution, by setting a cooling channel 21 inside the support plate 20, the coolant can carry away the heat generated by the photovoltaic panel 10 during the flow of the coolant in the cooling channel 21, thereby achieving the cooling and heat dissipation of the photovoltaic panel 10. At the same time, the heat dissipation fins 40 set on the lower end surface of the support plate 20 absorb and transfer heat from the photovoltaic panel 10 or the coolant during the heat dissipation process of the photovoltaic panel 10, thereby increasing the heat exchange area with the outside atmosphere and further improving the heat exchange effect.
[0034] Furthermore, since the end of the heat dissipation fin 40 facing away from the lower end face of the photovoltaic panel 10 is formed as an inclined plane 41, when the photovoltaic module 1 is placed on the ground, the inclined plane 41 contacts the ground, thereby enabling the support plate 20 and the photovoltaic panel 10 mounted on the support plate 20 to remain in an inclined state. There is no need to set up a support frame, which has the advantages of simple structure and convenient installation, and can reduce the production and installation costs of the photovoltaic module 1.
[0035] Furthermore, during the process of installing the photovoltaic panel 10 on the support plate 20, the limiting protrusions 30 formed on the two oppositely arranged sides of the support plate 20 and extending upward can limit and stop the photovoltaic panel 10 from both ends, thereby enabling the installation and positioning of the photovoltaic panel 10 without the need for fasteners, further simplifying the installation steps and achieving the purpose of reducing installation costs and improving assembly efficiency.
[0036] Regarding the tilt angle of the photovoltaic panel 10 mentioned above, in spring and autumn, the tilt angle is adjusted to be close to the local latitude; in summer, the tilt angle is appropriately reduced; and in winter, the tilt angle is appropriately increased. For example, in a region with a latitude of 40°, the tilt angle can be set to around 40° in spring and autumn, adjusted to 25°-30° in summer, and adjusted to 55°-60° in winter. Thus, when designing the heat dissipation fins 40, the tilt plane 41 of the heat dissipation fins 40 can be set within the above range to improve the efficiency of solar radiation reception.
[0037] To further improve heat dissipation, optionally, in this disclosure, such as Figure 1 and Figure 2 As shown, there can be multiple heat dissipation fins 40, which are spaced apart along the length or width of the support plate 20. Multiple heat dissipation fins 40 can further increase the contact area with the outside atmosphere, thereby facilitating faster and more efficient heat dissipation into the outside atmosphere and improving the heat dissipation effect on the photovoltaic panel 10.
[0038] In one embodiment provided in this disclosure, such as Figure 1 and Figure 2 As shown, optionally, the height of the heat dissipation fins 40 gradually decreases along the direction from one end of the support plate 20 to the other. This results in one end of the support plate 20 being higher than the other end when the heat dissipation fins 40 are in contact with the ground, i.e., the support plate 20 remains in an inclined state.
[0039] like Figure 1 and Figure 2 As shown, in the embodiment where there are multiple heat dissipation fins 40, each heat dissipation fin 40 has an inclined plane 41 formed at the end opposite to the support plate 20, and the multiple inclined planes 41 formed by the multiple heat dissipation fins 40 are arranged in the same plane. Since each heat dissipation fin 40 has an inclined plane 41 at the end opposite to the support plate 20, and the multiple inclined planes 41 are located in the same plane, it ensures that multiple heat dissipation fins 40 are in contact with the ground simultaneously during installation. This improves the stability of the multiple heat dissipation fins 40 in supporting the support plate 20, and the inclined planes 41 have a larger contact area when in contact with the ground, making it easier for heat to be transferred to the ground through the heat dissipation fins 40, thereby improving the heat dissipation effect of the photovoltaic panel 10.
[0040] like Figure 1 As shown, optionally, the photovoltaic module 1 may also include a cooling fan 50, which is used to blow airflow onto the heat sink fins 40. The cooling fan 50 can blow air onto the heat sink fins 40, thereby increasing the amount of air that exchanges heat with the heat sink fins 40, and thus improving the heat exchange efficiency.
[0041] It should be noted that the cooling fan 50 can be electrically connected to the photovoltaic panel 10, that is, the photovoltaic panel 10 provides power for the operation of the cooling fan 50. In this way, there is no need to set up a power supply specifically for driving the cooling fan 50, which can further simplify the structure of the photovoltaic module 1.
[0042] like Figure 1 As shown, optionally, the gap between the cooling fan 50 and the two adjacent heat dissipation fins 40 is arranged opposite to each other. In this way, when the cooling fan 50 blows air, the airflow can flow through the gap between the adjacent heat dissipation fins 40, maximizing the heat exchange area between the fan and the heat dissipation fins 40 and improving the heat exchange effect.
[0043] like Figure 2 As shown, optionally, the lower end face of the support plate 20 may include a first region 201 and a second region 202 arranged adjacently. The heat dissipation fins 40 are disposed in the first region 201, and the cooling fan 50 is disposed in the second region 202. That is to say, the installation of the heat dissipation fins 40 and the installation of the cooling fan 50 are independent of each other and do not interfere with each other. Furthermore, installing the cooling fan 50 and the heat dissipation fins 40 in the adjacent first region 201 and second region 202 also facilitates the blowing operation of the cooling fan 50 on the heat dissipation fins 40.
[0044] like Figure 1 As shown, optionally, the liquid inlet 23 and the liquid outlet 24 can be formed on the same side of the support plate 20. Placing the liquid inlet 23 and the liquid outlet 24 on the same side simplifies the connection of the cooling system, reduces the pipe length, and makes installation and maintenance more convenient.
[0045] like Figure 1 As shown, optionally, the cooling channel 21 consists of multiple straight segments 211 and multiple curved segments 212. Along the length or width direction of the support plate 20, the multiple curved segments 212 are arranged parallel and spaced apart, with each curved segment 212 connecting every two adjacent straight segments 211. On one hand, setting the cooling channel 21 in a serpentine structure of multiple straight segments 211 and multiple curved segments 212 can increase the surface area of the cooling channel 21 and improve the contact area with air; on the other hand, as the coolant flows from one straight segment 211 to another, the design of the curved segments 212 can effectively guide the coolant flow, reduce flow resistance, optimize the flow path of the coolant in the cooling channel 21, thereby improving cooling efficiency.
[0046] This disclosure does not limit the connection method between the aforementioned limiting protrusion 30 and the support plate 20. For example, in one embodiment provided by this disclosure, the limiting protrusion 30 and the support plate 20 may optionally be manufactured as a single piece. This single-piece design can reduce assembly steps in the manufacturing process, lower production costs and time, and improve production efficiency. Furthermore, the aforementioned manufacturing method can enhance the strength and stability of the overall structure, reduce weaknesses caused by connection points, and thereby improve the durability of the photovoltaic module 1.
[0047] In another embodiment provided in this disclosure, the limiting protrusion 30 and the support plate 20 can also be connected in a detachable manner. In this way, the specific position of the limiting protrusion 30 fixed on the support plate 20 can be adjusted according to the actual installation requirements of photovoltaic panels 10 of different sizes, so as to achieve the limiting and fixing of photovoltaic panels 10 of different sizes.
[0048] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure. It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this disclosure will not further describe the various possible combinations.
[0049] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
