[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 , the utility model provides a technical solution: a photovoltaic diode assembly with uniform heat dissipation, comprising a photovoltaic diode body 1, and also comprising heat dissipation assemblies 2 arranged on both sides of the photovoltaic diode body 1;

[0022] The heat dissipation assembly 2 includes two groups of ventilation blocks 21 arranged on both sides of the photovoltaic diode body 1, two groups of heat dissipation plates 22 arranged on both sides of the photovoltaic diode body 1, and several groups of heat dissipation grids 23 arranged on both sides of the photovoltaic diode body 1. Several groups of step blocks 24 are fixed on the surface of the ventilation blocks 21. Ventilation grooves 25 are opened through the surface of each group of step blocks 24. The ends of the two groups of ventilation blocks 21 on the same side that are close to each other are fixedly connected.

[0023] In this embodiment: the stepped integral ventilation slots 25 are installed to ensure that the velocity of each group of wind flow is less affected by the resistance, while increasing the aperture for receiving the wind flow, thereby increasing the wind receiving area, so that the middle position can also achieve the same heat dissipation effect as the two side positions, and the heat dissipation is uniform, which can ensure that the heat can flow out quickly, thereby achieving more efficient heat dissipation.

[0024] See also Figure 1-4 The sizes of the groups of step blocks 24 gradually increase from low to high, and the sizes of the ventilation slots 25 gradually increase from low to high.

[0025] In this embodiment: when the photovoltaic diode body 1 is subjected to wind flow at a high place, several groups of ventilation slots 25 receive the wind flow. Since the step blocks 24 on the surface of the ventilation block 21 are arranged in steps and the size of the ventilation slots 25 increases in steps, the wind flow from the outside to the inside of the step blocks 24 can be increased. The stepped integral ventilation slots 25 ensure that the flow velocity of each group of wind flow is reduced by the influence of resistance, while increasing the aperture for receiving the wind flow.

[0026] See also Figure 1-3 A plurality of groups of heat dissipation grids 23 are fixed on one side of the ventilation block 21 , and the heat dissipation plate 22 is fixed on a side of the heat dissipation grids 23 away from the ventilation block 21 .

[0027] In this embodiment, the purpose of the heat dissipation grid 23 is to increase the heat dissipation area and transfer the internal heat to the ventilation plate to enable better heat dissipation.

[0028] See also Figure 1-5 Through grooves 26 are provided on both sides of the photovoltaic diode body 1 , the heat sink 22 is arranged inside the through groove 26 , and a part-shaped groove 27 is provided on one side of the heat sink 22 .

[0029] In this embodiment, the shape of the part-shaped groove 27 is adapted to the shape of the parts inside the photovoltaic diode body 1 , and a better heat dissipation effect is achieved by fitting the part-shaped groove 27 with the parts inside the photovoltaic diode body 1 .

[0030] See also Figure 1-3 The top and bottom of the ventilation block 21 are fixed with fixing blocks 28, and the surface of the photovoltaic diode body 1 is provided with a plurality of groups of thread grooves, and the fixing blocks 28 are fixed to the photovoltaic diode body 1 by screws.

[0031] In this embodiment: the fixing block 28 is used to fix the ventilation pipe.

[0032] See also Figure 1-4 A sealing gasket 29 is provided at the connection between the photovoltaic diode body 1 and the ventilation block 21 .

[0033] In this embodiment: the sealing gasket 29 between the photovoltaic diode body 1 and the ventilation block 21 is used to complete the sealing of the device.

[0034] During operation, when the photovoltaic diode body 1 is subjected to wind flow at a high altitude, a number of groups of ventilation slots 25 receive the wind flow. Since the step blocks 24 on the surface of the ventilation block 21 are arranged in steps and the size of the ventilation slots 25 increases in a stepwise manner, the wind flow from the outside to the inside of the step blocks 24 can be increased. The stepped integral ventilation slots 25 ensure that the velocity of each group of wind flow is less affected by resistance, while increasing the aperture for receiving the wind flow, and heat dissipating the inside of the photovoltaic diode body 1 through the heat dissipation grid 23.

[0035] In summary, the device uses stepped integral ventilation slots to ensure that the velocity of each group of wind flow is less affected by resistance, while increasing the aperture for receiving the wind flow, thereby increasing the wind receiving area, so that the middle position can also achieve the same heat dissipation effect as the two side positions, and the heat dissipation is uniform, which can ensure that the heat can flow out quickly and achieve more efficient heat dissipation.
