Abstract
The utility model provides a circulating water cooling solar cell module, comprising a glass, a first EVA, a solar cell piece structure unit, a second EVA, and a backboard arranged from top to bottom in sequence. An EVA waterproof board and a rear cover are disposed under the backboard in sequence. The glass, the first EVA, the solar cell piece structure unit, the second EVA, the backboard, the EVA waterproof board, and the rear cover are fixed by a frame. The rear cover raises outward to form a heat exchanging chamber. The rear cover is provided with a water inlet, a water outlet, a lead access, and a junction box. An electrode leading-out line of the solar cell piece structure unit passes through the lead access and is connected with the junction box. Edges of the rear cover, and the lead access are bonded with the EVA waterproof board by sealing silica gel. The circulating water cooling solar cell module is good in cooling effect, and is simple in structure, low in cost, and can effectively come into use.
Description
[technical field]
The utility model relates to a kind of solar module, particularly a kind of recirculated water cooling solar module, and it can be widely used on photovoltaic plant.
[background technology]
Conventional solar cell assembly is generally by glass, EVA layer (the English full name of described EVA: Ethylene Vinyl Acetate, ethylene-vinyl acetate copolymer), solar battery sheet construction unit, TPT backboard, terminal box, edge frame made of aluminum profiles form Chinese:, described solar battery sheet construction unit is to be mutually in series by solar battery sheet.Described solar battery sheet construction unit is encapsulated between glass, EVA, TPT backboard, completely air-cooled by convection current, cooling effect extreme difference.The temperature of solar module continues to remain on higher temperature, will reduce the generating efficiency of solar module, shortens the useful life of solar module.
The cooling means of solar module comprises at present: convection current is cooling, microtubule is cooling, water cooling.
At rear surface of solar cell, by natural air or forced convertion salband, walk heat, to reach the object that reduces temperature, this mode is simple in structure, good economy performance, but radiating effect is poor.But also can reach radiating effect complex manufacturing although microtubule is cooling, cost is high, still needs hydrous water cooling means, complex structure, cost is high, is unfavorable for effectively coming into operation.
[summary of the invention]
The technical problems to be solved in the utility model, is to provide a kind of recirculated water cooling solar module, its good heat dissipation effect and simple in structure, with low cost.
The utility model is achieved in that
A kind of recirculated water cooling solar module, comprise the glass, one the one EVA, a solar battery sheet construction unit, one the 2nd EVA, the backboard that set gradually from top to bottom, below described backboard, also set gradually an EVA splash guard and a bonnet, described glass, an EVA, solar battery sheet construction unit, the 2nd EVA, backboard, EVA splash guard and bonnet are fixed by a frame; Described bonnet outwardly convex forms a heat-exchanging chamber, described bonnet is provided with a water inlet, a delivery port, lead-in wire path and a terminal box, the electrode outlet line of described solar battery sheet construction unit joins through described lead-in wire path and described terminal box, and described bonnet edge, lead-in wire path are all bonding by sealing silica gel and described EVA splash guard.
Further, described backboard is TPT backboard.
Further, described terminal box is bonding by sealing silica gel and described bonnet.
Further, described water inlet is located at the below of described bonnet, and described delivery port is located at the top of described bonnet, and becomes diagonal angle setting.
The utility model has the advantage of: by the bonnet of EVA splash guard and outwardly convex is set after backboard, form a heat-exchanging chamber, offer again a water inlet and a delivery port, form liquid flow path, liquid is fully taken away the heat that solar radiation produces in the process of turnover heat-exchanging chamber, thereby produces cooling effect.Meanwhile, the utility model is simple in structure, with low cost, can effectively come into operation.
[accompanying drawing explanation]
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model.
Fig. 2 is rearview of the present utility model.
Fig. 3 is side cross-sectional view of the present utility model.
Fig. 4 is end view of the present utility model.
[embodiment]
Refer to shown in Fig. 1 to Fig. 4, embodiment of the present utility model is described in detail.
Refer to Fig. 1 and Fig. 3, a kind of recirculated water cooling solar module, comprise described in the glass 1 that sets gradually from top to bottom, one the one EVA2(that EVA is the EVA layer that ethylene-vinyl acetate copolymer forms), a solar battery sheet construction unit 3, one the 2nd EVA4, a backboard 5, described backboard 5 also sets gradually an EVA splash guard 6 and a bonnet 7 below, and described glass 1, an EVA2, solar battery sheet construction unit 3, the 2nd EVA4, backboard 5, EVA splash guard 6 and bonnet 7 are fixing by a frame 8; Refer to Fig. 2 and Fig. 4, described bonnet 7 outwardly convexs form a heat-exchanging chamber 9, described bonnet 7 is provided with a water inlet 71, a delivery port 72, lead-in wire path 73 and a terminal box 74, the electrode outlet line 31 of described solar battery sheet construction unit 3 joins with described terminal box 74 through described lead-in wire path 73, and described bonnet 7 edges, lead-in wire path 73 are all bonding with described EVA splash guard 6 by sealing silica gel 10.In the present embodiment, described backboard is TPT backboard, and the logical 74 mistake sealing silica gel of described terminal box and described bonnet 7 are bonding, play waterproof effect.Described water inlet 71 is located at the below of described bonnet 7, described delivery port 72 is located at the top of described bonnet 7, and become diagonal angle setting, the benefit arranging is like this: the liquid for cools solar cell chip architecture unit 3 enters heat-exchanging chamber 9 by being located at the water inlet 71 of bonnet 7 belows, liquid is up walked from the bottom of heat-exchanging chamber 9, after being full of whole heat-exchanging chamber 9, from delivery port 72, flow out, fully take away the heat of whole solar battery sheet construction unit 3.If water inlet 71 and delivery port 72 are arranged conversely, flow rate of liquid is too fast, passes through fast heat-exchanging chamber 9, and the whole heat-exchanging chamber 9 of cannot flowing through, can only take away part heat, and cooling effect is just far short of what is expected.
The utility model is by arranging the bonnet 7 of EVA splash guard 6 and outwardly convex below at backboard 5, form a heat-exchanging chamber 8, offer again a water inlet 71 and a delivery port 72, form liquid flow path, liquid is fully taken away the heat that solar radiation produces in the process of turnover heat-exchanging chamber 8, thereby produces cooling effect.Meanwhile, the utility model is simple in structure, with low cost, can effectively come into operation.
The above, it is only the utility model preferred embodiment, therefore can not limit according to this scope that the utility model is implemented, the equivalence of doing according to the utility model the scope of the claims and description changes and modifies, and all should still belong in the scope that the utility model contains.
