Embodiment Construction
[0026] The present invention as Figure 1-2 As shown, it includes n conductors 1 and n-1 diodes 2 arranged in sequence and parallel to each other. Between conductors 1;
[0027] One end of the conductor 1 has a pin 10 , the pins 10 of the n conductors 1 are located on the same straight line, and the adjacent diodes 2 are arranged on both sides of the straight line. In this way, on the one hand, it can effectively avoid the problems of concentrated heat generation and local temperature rise of photovoltaic modules caused by too small spacing between adjacent diodes, too concentrated and located in the same area; on the other hand, the isolation of adjacent diodes Opening on both sides of the above-mentioned straight line also effectively avoids the problem that when a certain diode heats up due to the hot spot effect, the rest of the diodes still work in the reverse state, and the leakage current increases sharply, causing the problem of temperature rise. Combining the above ...

The invention provides a photovoltaic assembly and a junction box provided with the photovoltaic assembly and belongs to the field of photovoltaic assemblies, in particular to structural improvement of photovoltaic diodes and internal frames of the photovoltaic diodes. The photovoltaic assembly and the junction box provided with the photovoltaic assembly are exquisite in structure, good in use effect and stability, can effectively avoid the problems that local temperature is too high and heat dissipation is not uniform when used, and effectively prolong the overall service life of equipment. One end of each conductor is provided with a pin, the pins in n conductors are located in the same straight line, adjacent diodes are arranged on the two sides of the straight line, and n-1 diodes are arranged in the same direction and perpendicular to the conductors. The diodes are sequentially the first diode, the second diode and the third diode. The problems that local temperature is too high and heat dissipation is not uniform are effectively avoided, the overall use effect of the equipment is effectively improved, and the overall service life of the equipment is prolonged.
Description
technical field [0001] The invention relates to the field of photovoltaic modules, in particular to structural improvements of photovoltaic diodes and their internal frames. Background technique [0002] With the vigorous development of photovoltaic diodes, there are more and more types of junction boxes, coupled with cost constraints, people have more and more stringent requirements on the performance of diodes. In the traditional process, it is necessary to install the copper sheet in the junction box, install and weld the diode, which brings defects such as more processes, difficult operation and high scrap rate, and has become a technology that is urgently needed by those skilled in the art. question. [0003] In this regard, the National Bureau announced on May 30, 2012 a Chinese utility model patent titled "A High Temperature Resistant Photovoltaic Module Junction Box" with the application number "201120343941.7". The case consists of n diodes, n+ It consists of a co...
