Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic equipment, and in particular to a photovoltaic diode module and a photovoltaic junction box. Background Art

[0002] The hot spot effect of photovoltaic modules refers to the phenomenon that under certain conditions, the blocked or defective areas in the series branches of photovoltaic modules in the power generation state are treated as loads, consuming the energy generated by other areas, resulting in local overheating. This phenomenon is called the hot spot effect of photovoltaic modules. The hot spot effect will reduce the output power of photovoltaic modules to a certain extent, and if the heating temperature exceeds a certain limit, it will cause permanent damage such as partial burning of photovoltaic modules to form dark spots, melting of solder joints, aging of packaging materials, etc., which will affect the service life of photovoltaic modules and may even cause safety hazards.

[0003] In order to prevent photovoltaic modules from being damaged by the hot spot effect, one or more bypass diodes are usually added to the original circuit in the photovoltaic junction box to prevent the energy generated by the photovoltaic modules from being consumed by the obstructed or defective photovoltaic modules. Usually, the bypass diode is packaged in an axial, patch or modular structure. As the power requirements of photovoltaic modules are getting higher and higher, modular diodes are gradually becoming the mainstream. However, in the related art, modular diodes have the problem of low heat dissipation efficiency. Utility Model Content

[0033] As shown in FIG. 1 , a photovoltaic diode module according to an embodiment includes a first conductive sheet 110 , a second conductive sheet 120 , a diode chip 140 and a conductive jumper 130 .

[0034] The first conductive sheet 110 and the second conductive sheet 120 may both be copper sheets. The second conductive sheet 120 is located in the same plane as the first conductive sheet 110 and is spaced apart from the first conductive sheet 110 to ensure insulation from the first conductive sheet 110; wherein the second conductive sheet 120 and the first conductive sheet 110 are arranged along the first direction. The second conductive sheet 120 may include a bearing portion 122 and a second conductive body 121 connected to the bearing portion 122, and the bearing portion 122 is used to bear the diode chip 140, and one surface of the diode chip 140 may be welded to one surface of the bearing portion 122.

[0035] The conductive jumper 130 may be a copper jumper. The conductive jumper 130 covers the other surface of the diode chip 140; wherein the conductive jumper 130 includes a jumper body 131 and a plurality of corners 132 connected to the jumper body 131 (two corners 132-1 and 132-2 are exemplarily shown in FIG1 ), the jumper body 131 and the corners 132 may be located in different planes, and the positive projection of the diode chip 140 toward the conductive jumper 130 is located in the central area of ​​the jumper body 131, so that the heat of the diode chip 140 can be evenly dissipated to the second conductive sheet 120 and the conductive jumper 130, and each corner 132 is respectively arranged in contact with the first conductive sheet 110, and the contact arrangement is, for example, a welding arrangement, so that the contact area between the conductive jumper 130 and the first conductive sheet 110 is large.

[0036] In the photovoltaic diode module, since the diode chip 140 is located on the supporting portion 122 of the second conductive sheet 120, and the conductive jumper 130 covers the diode chip 140, the positive projection of the diode chip 140 toward the conductive jumper 130 is located in the central area of ​​the jumper body 131 of the conductive jumper 130, so that the heat of the diode chip 140 can be evenly dissipated to the second conductive sheet 120 and the conductive jumper 130. Furthermore, since the corners 132 of the conductive jumper 130 are respectively arranged in contact with the first conductive sheet 110, the contact area between the conductive jumper 130 and the first conductive sheet 110 is large, so that the heat dissipated to the conductive jumper 130 can be basically all dissipated to the first conductive sheet 110. Finally, the heat of the diode chip 140 is evenly dissipated via the first conductive sheet 110 and the second conductive sheet 120. The utilization rates of the first conductive sheet 110 and the second conductive sheet 120 in the heat dissipation process are basically the same and both are high, thereby improving the heat dissipation efficiency of the photovoltaic diode module.

[0039] In some embodiments, as shown in FIG. 2 , the conductive jumper 130 includes three corners 132-1, 132-2, and 132-3, wherein two of the corners 132-1 and 132-2 are located on both sides of the jumper body 131 in the second direction, and the other corner 132-3 is located on one side of the jumper body 131 close to the first conductive sheet 110 in the first direction, wherein the first direction intersects the second direction, that is, the first direction is perpendicular to the second direction.

[0042] In this embodiment, the conductive jumper 130 includes at least four corners 132 and the at least four corners 132 are respectively arranged in contact with the first conductive sheet 110, so that the contact area between the conductive jumper 130 and the first conductive sheet 110 is further increased, so that the heat dissipated to the conductive jumper 130 can be almost completely dissipated to the first conductive sheet 110; in the second direction, some of the at least four corners 132 are respectively located on both sides of the jumper body 131, and the remaining corners 132 of the at least four corners 132 in the first direction are respectively located on one side of the jumper body 131 close to the first conductive sheet 110, which is further conducive to the heat dissipated to the jumper body 131 being able to be smoothly dissipated to the first conductive sheet 110.

[0043] In some embodiments, the corner portion 132 is in a sheet shape, so that the corner portion 132 has a simple structure, is easy to implement, and is easy to weld with the first conductive sheet 110 , thereby easily transferring the heat dissipated to the jumper body 131 to the first conductive sheet 110 .

[0045] In some embodiments, at least one stress hole is provided on the conductive jumper 130 , and the stress hole can penetrate the conductive jumper 130 , thereby reducing the stress between the conductive jumper 130 and the first conductive sheet 110 and the diode chip 140 , and preventing the diode chip 140 from being damaged by stress.

[0046] Continuing to refer to Figure 2, in some embodiments, the first conductive sheet 110 includes a first conductive body 111 and a first connecting portion 112 and a second connecting portion 113 connected to the first conductive body 111; wherein the first connecting portion 112 and the second connecting portion 113 are arranged close to the second conductive sheet 120, and are connected to the first conductive body 111 to form an opening 114; at least a portion of the supporting portion 122 of the second conductive sheet 120 is located in the opening 114; in this way, the conductive jumper 130 is easily connected to the first conductive sheet 110, and the structure of the photovoltaic diode module is compact.

[0050] In some of the embodiments, a first tin groove and a second tin groove are respectively provided on the first conductive body 111 and the second conductive body 121. The first tin groove is used to carry the first tin sheet 151, and the second tin groove is used to carry the second tin sheet 152. The first tin sheet 151 and the second tin sheet 152 are used to connect photovoltaic modules. The busbars of the photovoltaic modules can be connected to the corresponding first tin sheets 151 and the second tin sheets 152 through the first bus holes 161 and the second bus holes 162, respectively.

[0051] In some of the embodiments, a first isolation groove and a second isolation groove are respectively provided on the first conductive body 111 and the second conductive body 121.
