Description
Technical field
The utility model relates to field of photovoltaic power generation, particularly a kind of photovoltaic junction box.
Background technology
In the electric connection technology of solar power system, adopt photovoltaic junction box to realize being connected of photovoltaic module and other electrical equipment usually.But general photovoltaic junction box is made up of housing, cover plate, aluminium base etc. that electronic component is housed; Housing and cover plate materials adopt making such as plastics and rubber; Heat dispersion is poor; The heat that electronic component on the aluminium base produces can't dispel the heat through terminal box itself again, causes photovoltaic junction box not long useful life.
The utility model content
The technical problem that (one) will solve
The problem that the utility model will solve is the heat dissipation problem that solves the electronic component on the aluminium base in the photovoltaic junction box, improves the heat dispersion of photovoltaic junction box.
(2) technical scheme
For addressing the above problem, the utility model provides a kind of photovoltaic junction box, and said terminal box comprises aluminium base, housing and cover plate; Said cover plate is connected with housing; This cover plate is that aluminum is made; Perfect heat-dissipating, said aluminium base is contained in the housing, the front electronic components of this aluminium base; And the back side of this aluminium base fully contacts with cover plate, and its effect is to dispel the heat for the heat that produces the electronic component on the aluminium base conducts to cover plate.
In the above-mentioned photovoltaic junction box, it also comprises spring, and said spring one end and aluminium base are fixed; The other end is installed in the connecting hole of housing; Its effect is for the bounce through spring, is close to aluminium base and cover plate more, and more effective conduction heat is realized heat radiation.
In the above-mentioned photovoltaic junction box; Between the back side of the inboard of cover plate and aluminium base, be lined with one deck heat conductive silica gel; Said heat conductive silica gel has insulation function and increases the heat conduction function; Not only can insulation function prevent that the inner voltage that produces of terminal box is outwards creepage through cover plate, can increase the heat conduction function again and better conduct heat and realize heat radiation that it is tightr that aluminium base is connected with cover plate.
(3) beneficial effect
The cover plate of the photovoltaic junction box of the utility model is used aluminum instead and is processed, and aluminium base fully contacts with cover plate, through cover plate heat radiation, good heat dissipation effect, prolongs photovoltaic junction box useful life.
Description of drawings
Fig. 1 is the cutaway view of the photovoltaic junction box of the utility model;
Fig. 2 is the enlarged drawing of A among photovoltaic junction box Fig. 1 of the utility model;
1 is that cover plate, 2 is that aluminium base, 3 is that spring, 4 is that housing, 5 is that connecting hole, 6 heat conductive silica gels, 7 are that the back side, 8 is that front, 9 is an electronic component among the figure.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
Like Fig. 1, shown in Figure 2, the utility model provides a kind of photovoltaic junction box, said terminal box comprise aluminium base 2,, housing 4 and cover plate; Said cover plate 1 is connected with housing 4; This cover plate 1 is that aluminum is made; Perfect heat-dissipating, said aluminium base 2 is contained in the housing 4, front 8 electronic components 9 of this aluminium base 2; And the back side 7 of this aluminium base 2 fully contacts with cover plate 1, and its effect is to conduct to cover plate 1 heat radiation for the heat that produces the electronic component on the aluminium base 29.
In the above-mentioned photovoltaic junction box, also comprise spring 3, said spring 3 one ends and aluminium base 2 are fixing; The other end is installed in the connecting hole 5 of housing 4; Its effect is for the bounce through spring 3, is close to aluminium base 2 and heat conductive silica gel 6 more, and is more effective conduction heat realization heat radiation.
In the above-mentioned photovoltaic junction box; Between the back side 7 of the inboard of cover plate 1 and aluminium base 2, be lined with one deck heat conductive silica gel 6; Said heat conductive silica gel 6 has insulation function and increases the heat conduction function; Not only can insulation function prevent that the inner voltage that produces of terminal box is outwards creepage through cover plate 1, again can the heat conduction function better conduct heat and realize heat radiation, can also make aluminium base 2 be connected tightr with cover plate 1.
When photovoltaic junction box used, the electronic component on the aluminium base 2 was started working, and the heat of generation is through aluminium base 2, and heat conductive silica gel 6 outwards conducts with cover plate 1, realizes heat radiation.
The cover plate 1 of the photovoltaic junction box of the utility model is used aluminum instead and is processed, and aluminium base 2 fully contacts with cover plate 1, and through cover plate 1 heat radiation, good heat dissipation effect prolongs photovoltaic junction box useful life.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
