Abstract
The utility model relates to a high efficient flat plate solar heat collector. A heat absorbing plate is arranged in a casing, a heat-insulating layer is arranged at the lower part of the heat absorbing plate, and a glass cover plate is closured at the upper part of the casing. The utility model is characterized in that a transparent thermal baffle is arranged between the glass cover plate and the heat absorbing plate in the casing. Because an isolated hollow cavity which is formed between the transparent thermal baffle and the heat absorbing plate can suppress the free convection of the air, the loss of the convection heat transfer is reduced, and the thermal efficiency of the heat collector is improved greatly; the utility model is beneficial to improve the water yield and the water temperature of the heat collector, and to make the days supplied effectively for the hot water by the heat collector in a year increased largely.
Description
The utility model belongs to the architecture advances of flat-plate solar collector.
Flat type solar heat collector is low with its cost, durable reliable, easy to install and be subjected to people's welcome, but the absorber plate in the flat type solar heat collector is the below that directly is contained in the glass cover-plate of housing at present, cross-ventilation between glass cover-plate and the absorber plate causes bigger surperficial heat waste, thereby the thermal efficiency is on the low side, and is strong inadequately in solar radiation, or require under the high slightly situation of water temperature, the heat production water yield and the water temperature of heat collector just can significantly descend.The purpose of this utility model is to avoid the weak point of existing flat type solar heat collector structure, proposes a kind ofly can reduce the surperficial heat waste that cross-ventilation causes in the heat collector, thus the flat-plate solar collector efficiently of the raising thermal efficiency.
The purpose of this utility model is achieved in that
A kind of flat-plate solar collector efficiently is provided with absorber plate in housing, the bottom of absorber plate is a heat-insulation layer, and the top capping glass cover-plate of housing is characterized in that being provided with a transparent thermal baffle between glass cover-plate in the housing and the absorber plate.
Transparent thermal baffle that the utility model is set and the spacing between the absorber plate are advisable to be not more than 4cm.
Set transparent thermal baffle is transparent, can guarantee seeing through to be absorbed by absorber plate of solar radiation, forms the isolation cavity between transparent thermal baffle and the absorber plate and can suppress free convection, thereby reduce the heat convection loss.
The bottom of transparent thermal baffle of the present utility model can have fin, makes the cavity between transparent thermal baffle and the absorber plate be separated into a plurality of little separate spaces, the heat loss that causes with further inhibition cross-ventilation wherein, thus improve the effect of heat insulation of transparent thermal baffle.
The utility model to reduce heat collector surface heat waste, has improved the thermal efficiency with simple architecture advances greatly, helps improving the aquifer yield and the water temperature of heat collector, and the number of days of heat collector effective heat supply water in 1 year is increased greatly, and effect is fairly obvious.
Below be drawing explanation of the present utility model:
Fig. 1 is the structural representation of flat-plate solar collector efficiently.
Among the figure: 1 is housing, and 2 is glass cover-plate, and 3 is transparent thermal baffle, and 3a is a fin, and 4 is absorber plate, and 4a is the limbers of absorber plate, and 5 is heat-insulation layer.
Be described further below in conjunction with the CONSTRUCTED SPECIFICATION of accompanying drawing the utility model embodiment:
As shown in Figure 1, in the housing 1 of heat collector, between glass cover-plate 2 and absorber plate 4, be provided with transparent thermal baffle 3, the bottom of transparent thermal baffle has fin 3a, transparent thermal baffle adopts lucite or makrolon material to make, spacing between transparent thermal baffle 3 and the absorber plate 4 is 3cm, is filled with insulation material in the bottom of absorber plate 4 and forms heat-insulation layer.This high-efficient flat-plate solar thermal collector is compared with common flat plate collector, and the raising of its thermal efficiency can reach 30%.
