Description
Technical field
The utility model relates to field of solar thermal power generation, relates to a kind of integrated bypass module that is used for solar junction box concretely.
Background technology
At present, solar power generation has two kinds of forms.A kind of is light-Re-electricity conversion, and another kind is light-electricity conversion.Wherein the basic principle of light-electricity conversion is to utilize photovoltaic effect that solar radiant energy directly is converted to electric energy.Light-the power conversion circuit of prior art comprises many group photovoltaic generation board components, and with the terminal box that photovoltaic generation plate two ends are electrically connected, terminal box comprises the bypass module that housing and the bypass diode in parallel with the photovoltaic generation plate constitute.Wherein bypass module is used for providing other current path when the photovoltaic generation plate is hidden shadow or is out of order.
Diode in the bypass module, owing to the current delivery effect of photovoltaic generation plate is generated heat, when the diode temperature of bypass module is too high, diode will be by thermal breakdown, then diode can not play the effect of bypass, therefore, bypass module to possess good performance of heat dissipation, could ensure that the photovoltaic generation plate is hidden shadow or the effect of current bypass is provided when being out of order.The bypass module of existing structure is to adopt discrete diode separately with every group of photovoltaic generation plate and connect distribution.Heat radiation in the terminal box is mainly dispelled the heat by bypass diode plastic packaging and lead-in wire.Its area of dissipation is less, causes heat dispersion relatively poor.
The utility model content
Technical problem to be solved in the utility model is, overcomes above deficiency, and a kind of integrated bypass module that is used for solar power generation of good heat dispersion performance is provided.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of integrated bypass module that is used for solar power generation, comprise a plurality of bypass diodes that are connected to the photovoltaic generation board component, also comprise aluminium base, described aluminium base is electrically connected with many group negative terminal pad, described every group of negative terminal pad is electrically connected with negative terminals that is fixed on the aluminium base, and described negative terminals is electrically connected with the negative terminal of photovoltaic generation board component; Described aluminium base is provided with one deck flexible circuit plate, described flexible circuit plate is provided with the positive terminal pad that matches with negative terminal pad, described each positive terminal pad is electrically connected with positive terminal, described positive terminal adopts insulation mode to be fixed on the aluminium base, and described positive terminal is electrically connected with the anode of photovoltaic generation plate; The cathode weld of described bypass diode is on negative terminal pad, and the anodic bonding of described bypass diode is connected on the positive terminal pad.
Further, described bypass diode adopts stamp-mounting-paper diode.
Further, described bypass diode adopts the diode of COB encapsulation.
The beneficial effects of the utility model are: the utility model is used for the integrated bypass module of solar power generation, is the bypass diode that is connected to the photovoltaic generation board component with a plurality of, be welded on the aluminium base that has a flexible circuit plate, rather than dispersed and distributed independently.When the electric current of photovoltaic generation plate is flowed through the bypass diode of bypass module, the electric current heat part of diode is dispersed into the space by the encapsulation of diode, when another part electric current heat passes through the negative electrode of bypass diode, be dispersed into the space by the aluminium base that is electrically connected with negative terminal pad.Because the area of aluminium base is bigger than the area of the plastic packaging of discrete diode and lead-in wire, so the area of dissipation of aluminium base is also big than discrete diode radiating area, good heat dispersion performance promptly of the present utility model.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Shown in Fig. 1-5, a kind of integrated bypass module that is used for solar power generation of the utility model, comprise a plurality of bypass diode D that are connected to the photovoltaic generation board component, also comprise aluminium base 1, described aluminium base 1 is electrically connected with many group negative terminal pad 5, and described every group of negative terminal pad 5 is electrically connected with negative terminals 4 that is fixed on the aluminium base 1; Described aluminium base 1 is provided with one deck flexible circuit plate 2, described flexible circuit plate 2 is provided with the positive terminal pad 7 that matches with negative terminal pad 5, described each positive terminal pad 7 is electrically connected with positive terminal 3, and described positive terminal 3 adopts insulation mode to be fixed on the aluminium base 1; The cathode weld of described bypass diode D is on negative terminal pad 5, and the anodic bonding of described bypass diode D is connected on the positive terminal pad 7.
Bypass diode D can adopt stamp-mounting-paper diode, also can adopt the diode of COB encapsulation, the encapsulation of the bare chip that is about to diode after with point gum machine point glue.Stamp-mounting-paper diode just can directly be welded on stamp-mounting-paper diode on the pad of integrated bypass module, and production technology is promptly convenient simply again.COB encapsulates, and carry out the step of a glue, but its low cost of manufacture.
The utility model is used for the integrated bypass module of solar power generation, is the bypass diode D that is connected to the photovoltaic generation board component with a plurality of, be welded on the aluminium base 1 that has a flexible circuit plate, rather than dispersed and distributed independently.When the electric current of photovoltaic generation plate is flowed through the bypass diode D of bypass module, the electric current heat part of diode relies on the encapsulation of diode to be dispersed into the space, when another part electric current heat passes through the negative electrode of bypass diode D, be dispersed into the space by the aluminium base 1 that is electrically connected with negative terminal pad 4.Because the area of aluminium base 1 is bigger than the area of the plastic packaging of discrete diode and lead-in wire, so the area of dissipation of aluminium base is also big than discrete diode radiating area, good heat dispersion performance promptly of the present utility model.
