[0032] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0033] Example 1

[0034] refer to Figure 1 As shown, an embodiment of the present application provides a heat dissipation structure 100 , which includes a mounting plate 110 , a plurality of heat dissipation pipes 120 , a plurality of heat dissipation fins 130 and a heat dissipation fan 140 .

[0035] Specifically, combined Figure 1 and Figure 2 As shown, the mounting plate 110 is provided with a plurality of through grooves 111; each of the heat dissipation pipes 120 is arranged in one of the through grooves 111, and the plurality of heat dissipation pipes 120 can form a heat dissipation channel; each of the heat dissipation fins 130 is arranged between the heat dissipation pipe 120 and the groove wall of the through groove 111; the heat dissipation fan 140 is installed at the opening position of the heat dissipation channel, and the mounting plate 110 is convenient for being installed close to the photovoltaic module and the photovoltaic building to improve the heat dissipation effect of the heat dissipation structure 100, the heat dissipation fins 130 are arranged in the through grooves 111, and the heat dissipation pipes 120 are used to be installed in the through grooves 111, and the heat dissipation pipes 120 are convenient for heat transmission and dissipation, and the plurality of through grooves 111 are all installed with heat dissipation pipes 120 to facilitate heat dissipation, and the heat dissipation pipes 120 can be cooled by the heat dissipation fins 130 to improve the overall heat dissipation area, and the heat dissipation fan 140 is used to accelerate the air heat exchange between the heat dissipation pipes 120 and the heat dissipation fins 130 to achieve the purpose of heat dissipation and cooling.

[0036] It is understandable that the heat dissipation fins 130 increase the surface area and thus the heat exchange area, so that the heat can be transferred from the heat source to the surrounding cooler air or fluid more quickly, ensuring that the hot air can be effectively taken away and replaced by the cold air, thereby achieving more effective heat conduction and convection heat exchange. The structure of the heat dissipation fins 130 can be straight or needle-shaped, and the structure of the heat dissipation fins 130 can also be wavy, without specific limitation. The heat dissipation fan 140 drives the air flow through the rotating blades, thereby enhancing the heat dissipation effect. When used in conjunction with the heat dissipation fins 130, the fan can accelerate the exchange process between the heat on the fin surface and the surrounding air, thereby improving the heat dissipation efficiency.

[0037] Exemplarily, the heat pipe 120 and the heat fin 130 can be fixed in the through slot 111 of the mounting plate 110 by gluing. The heat pipe 120 and the heat fin 130 can be made of copper, aluminum, or copper-aluminum alloy, or other materials with good thermal conductivity, which will not be described in detail here.

[0038] like Figure 1 , Figure 3 and Figure 4 As shown, the heat dissipation structure 100 has a first direction and a second direction, and the first direction is set at an angle to the second direction. Exemplarily, the first direction is taken as the width direction of the heat dissipation structure 100, and the second direction is taken as the length direction of the heat dissipation structure 100, and the first direction and the second direction are perpendicular to each other. It can be understood that the above definition is only for the convenience of understanding the relative position relationship of each part in the heat dissipation structure 100, and should not be understood as a limitation to the present application.

[0039] In one embodiment, optionally, reference Figure 3 As shown, the number of the heat dissipation channel is one, and two adjacent heat dissipation tubes 120 are connected via a connecting tube 121, so that a plurality of heat dissipation tubes 120 can jointly form a heat dissipation channel. Accordingly, the opposite ends of the plurality of heat dissipation tubes 120 are connected in sequence via the connecting tube 121 to form a heat dissipation channel, and the purpose of heat dissipation and cooling of the mounting plate 110 is achieved through the heat dissipation channel.

[0040] Optionally, a cooling fan 140 is provided at the interface between two adjacent cooling tubes 120. Exemplarily, the cooling fan 140 is provided between the connecting tube 121 and the cooling tube 120, and the cooling fan 140 can blow cold air to the cooling tube 120 in a directional manner, accelerate the heat exchange in the cooling channel and take away the heat.

[0041] Optionally, along the first direction, the heat dissipation fins 130 are located on the circumferential outer side of the heat dissipation pipe 120. The heat dissipation fins 130 are installed on the circumferential outer side of the heat dissipation pipe 120. The heat dissipation fins 130 increase the surface area of ​​the heat dissipation pipe 120 to improve the heat exchange efficiency and are used to dissipate heat and cool the heat dissipation pipe 120. Exemplarily, the plurality of heat dissipation fins 130 are all located in the through slot 111, which reduces the space occupancy of the heat dissipation fins 130 and has a relatively compact structure.

[0042] In one embodiment, optionally, the plurality of through grooves 111 are located on opposite sides of the mounting plate 110 or the plurality of through grooves 111 are located on one side of the mounting plate 110. It can be understood that one side of the mounting plate 110 is provided with through grooves 111 for cooling and dissipating the heat of the mounting plate 110, or through grooves 111 are provided on opposite sides of the mounting plate 110, so that the heat pipes 120 and the heat fins 130 can be located on opposite sides of the mounting plate 110, and heat exchange can be achieved on opposite sides of the mounting plate 110, thereby improving the heat dissipation and cooling efficiency.

[0043] In summary, the heat dissipation structure 100 can be applied to photovoltaic modules or photovoltaic buildings. The heat dissipation structure 100 is improved, and the mounting plate 110 is convenient for close installation on photovoltaic modules and photovoltaic buildings to improve the heat dissipation effect of the heat dissipation structure 100. The heat dissipation fins 130 are arranged in the through grooves 111, and the heat dissipation pipes 120 are used to be installed in the through grooves 111. The heat dissipation pipes 120 are convenient for heat transmission and loss. Multiple through grooves 111 are installed with heat dissipation pipes 120 to facilitate heat dissipation. The heat dissipation pipes 120 can be dissipated by the heat dissipation fins 130 to improve the overall heat dissipation area. The heat dissipation fan 140 is used to accelerate the air heat exchange between the heat dissipation pipes 120 and the heat dissipation fins 130 to achieve the purpose of heat dissipation and cooling, thereby improving the heat dissipation effect of the heat dissipation pipes 120.

[0044] Example 2

[0045] refer to Figure 1 As shown, an embodiment of the present application provides another heat dissipation structure 100 , which includes a mounting plate 110 , a plurality of heat dissipation pipes 120 , a plurality of heat dissipation fins 130 and a heat dissipation fan 140 .

[0046] Specifically, combined Figure 1 and Figure 2 As shown, the mounting plate 110 is provided with a plurality of through slots 111; each of the heat dissipation pipes 120 is provided in one of the through slots 111, and the plurality of heat dissipation pipes 120 can form a heat dissipation channel, so that the mounting plate 110 can be installed close to the photovoltaic module and the photovoltaic building, thereby improving the heat dissipation effect of the heat dissipation structure 100. For example, the mounting plate 110 can be made of corrugated metal plate.

[0047] In this embodiment, each of the heat dissipation fins 130 is arranged between the heat dissipation pipe 120 and the groove wall of the through groove 111; the heat dissipation fan 140 is installed at the opening position of the heat dissipation channel, the heat dissipation fins 130 are arranged in the through groove 111, and the heat dissipation pipe 120 is used to be installed in the through groove 111. The heat dissipation pipe 120 is convenient for the transmission and dissipation of heat. Multiple through grooves 111 are installed with heat dissipation pipes 120 to facilitate heat dissipation. The heat dissipation pipe 120 can be cooled by the heat dissipation fins 130 to increase the overall heat dissipation area. The heat dissipation fan 140 is used to accelerate the air heat exchange between the heat dissipation pipe 120 and the heat dissipation fins 130 to achieve the purpose of heat dissipation and cooling.

[0048] The heat pipe 120 and the heat fin 130 may be made of copper, aluminum or copper-aluminum alloy, or other materials with good thermal conductivity, which will not be described in detail here.

[0049] like Figure 1 , Figure 3 and Figure 4 As shown, the heat dissipation structure 100 has a first direction and a second direction, and the first direction is set at an angle to the second direction. For example, the first direction is the width direction of the heat dissipation structure 100, and the second direction is the length direction of the heat dissipation structure 100, and the first direction and the second direction are perpendicular to each other.

[0050] In one embodiment, optionally, reference Figure 4 As shown, there are multiple heat dissipation channels. One heat dissipation pipe 120 can form one heat dissipation channel. Correspondingly, multiple heat dissipation pipes 120 can form multiple heat dissipation channels. The multiple heat dissipation channels respectively exchange heat and jointly achieve heat dissipation and cooling of the mounting plate 110, thereby having a better heat dissipation effect.

[0051] Optionally, along the first direction, combined Figure 1 and Figure 4 As shown, the plurality of heat dissipation pipes 120 are arranged in parallel, and accordingly, along the width direction of the mounting plate 110, the plurality of heat dissipation pipes 120 arranged in parallel form a plurality of heat dissipation channels, and adjacent heat dissipation channels will not affect or hinder each other. Exemplarily, along the width direction of the mounting plate 110, a plurality of through slots 111 are arranged in parallel.

[0052] Optionally, along the second direction, such as Figure 4As shown, the multiple heat dissipation fins 130 are spaced apart and arranged in parallel, and the second direction is perpendicular to the first direction, that is, each through slot 111 is provided with a plurality of heat dissipation fins 130, and there is a certain distance between adjacent heat dissipation fins 130. The arrangement of the multiple heat dissipation fins 130 affects the air flow permeability and heat exchange area. The multiple heat dissipation fins 130 can strike a balance between increasing the heat dissipation surface area and reducing the material consumption, and can achieve better heat dissipation and cooling effects while taking into account the material cost of the multiple heat dissipation fins 130.

[0053] Optionally, along the first direction, the heat dissipation fins 130 are located on the circumferential outer side of the heat dissipation pipe 120. The heat dissipation fins 130 are installed on the circumferential outer side of the heat dissipation pipe 120. The heat dissipation fins 130 increase the surface area of ​​the heat dissipation pipe 120 to improve the heat exchange efficiency and are used to dissipate heat and cool the heat dissipation pipe 120. Exemplarily, the plurality of heat dissipation fins 130 are all located in the through slot 111, which reduces the space occupancy of the heat dissipation fins 130 and has a relatively compact structure. Exemplarily, the diameter of the heat pipe 120 is D1, and the cross-sectional dimension of the through groove 111 is D2, satisfying 0.3D2≤D1≤0.5D2, that is, the diameter D1 of the heat pipe 120 is greater than or equal to 0.3 of the cross-sectional dimension D2 of the through groove 111, ensuring that the diameter D1 of the heat pipe 120 has a sufficient size to ensure that the heat dissipation channel has a better heat dissipation and cooling effect, the diameter D1 of the heat pipe 120 is less than or equal to 0.5 of the cross-sectional dimension D2 of the through groove 111, and a preset part of the area space is used to set the heat dissipation fins 130, and the heat dissipation surface area of ​​the heat pipe 120 is increased by the heat dissipation fins 130 to achieve heat dissipation and cooling of the heat pipe 120.

[0054] In one embodiment, optionally, a plurality of through slots 111 are located on opposite sides of the mounting plate 110 or a plurality of through slots 111 are located on one side of the mounting plate 110. It is understood that a through slot 111 is provided on one side of the mounting plate 110 for cooling and dissipating the heat of the mounting plate 110, which facilitates the installation of the heat dissipation structure 100, reduces the difficulty of assembly, and improves the installation efficiency. Alternatively, through slots 111 are provided on opposite sides of the mounting plate 110, so that the heat pipe 120 and the heat dissipation fin 130 can be located on opposite sides of the mounting plate 110, and heat exchange can be achieved on opposite sides of the mounting plate 110, thereby improving the heat dissipation and cooling efficiency.
