Abstract

The utility model provides a flat type solar heat collector with low heat loss. The heat collector comprises a frame, a sealed treadle bar, a piece of daylighting glass, a heat preservation air layer, a heat absorption piece, a heat transfer medium pipe and a heat preservation layer, wherein the back surface of the daylighting glass is stuck with a transmission thermal insulating film; a combination of the heat absorption piece and the heat transfer medium pipe has the back surface stuck with a space capsule thermal insulating film; and thermal insulating strips are additionally arranged in the periphery where the frame contacts the heat preservation air layer. The flat type solar heat collector effectively controls heat loss channels, thereby greatly reducing the heat loss and improving the heat absorption efficiency of the flat type solar heat collector; the tests show that under the same testing conditions, the flat type solar heat collector with low heat loss has the heat absorption efficiency improved by 15 to 20 percent compared with the prior similar product.

Description

The flat type solar heat collector of low heat waste

Technical field:

The utility model relates to a kind of flat solar water heater, relates in particular to flat type solar heat collector.

Background technology:

Existing flat type solar heat collector as shown in Figure 1, form by frame 1, seal trim strip 2, daylighting glass 3, insulation gas-bearing formation 4, heat absorbing sheet 5, heat transfer medium pipe 6, heat-insulation layer 7, daylighting glass 3 and heat absorbing sheet 5 all are installed on the frame 1, insulation gas-bearing formation 4 is between daylighting glass 3 and heat absorbing sheet 5, heat-insulation layer 7 is fixedly installed on the back side of heat absorbing sheet 5, heat transfer medium pipe 6 equally spaced is distributed in the heat absorbing sheet 5, daylighting glass 3 by seal trim strip 2 press seals on frame 1.The heat-insulating property of the flat type solar heat collector of this structure is relatively poor, the heat part that heat absorbing sheet 5 is absorbed is absorbed by the heat transfer medium in the heat transfer medium pipe 6 and reaches attemperater, another part raises the gas temperature in the insulation gas-bearing formation 4, part heat in the insulation gas-bearing formation 4 loses by metal edges framework 1 and daylighting glass 3, a part of heat simultaneously also will scatter and disappear from the back side of the combination of heat absorbing sheet 5 and heat transfer medium pipe 6, through test, by above-mentioned approach institute dispersed heat account for that whole flat-plate solar collector heat scatters and disappears 60%～70%, it is the main path that existing flat-plate solar collector heat scatters and disappears, because the heat waste of existing flat type solar heat collector is higher, thereby the flat solar water heater does not obtain large scale application yet.The utilization of solar energy is more and more paid attention in countries in the world at present, solar energy and architecture-integral design have been risen to quite high scientific research position, Jiangsu Province Department of Construction is file publishing, newly-built skyscraper below 12 layers has been proposed mandatory requirement, solar energy be must carry out and integrated design and construction carried out, because the flat solar water heater is and the best matching used solar facilities of skyscraper, it will enter the research of a new round, apply period, at present, people press for a kind of flat-plate solar heat collector of low heat waste, to adapt to the demand of skyscraper balcony formula high-efficient flat-plate solar water heater.

The utility model content:

In order to improve the heat absorption efficiency of flat type solar heat collector, it is crucial that the heat that reduces flat type solar heat collector scatters and disappears, and the purpose of this utility model is to provide a kind of flat type solar heat collector of low heat waste.

Technical solution adopted in the utility model is:

The flat type solar heat collector of described low heat waste, comprise frame 1, seal trim strip 2, daylighting glass 3, insulation gas-bearing formation 4, heat absorbing sheet 5, heat transfer medium pipe 6, heat-insulation layer 7, heat transfer medium pipe 6 equally spaced is distributed in the heat absorbing sheet 5, daylighting glass 3 by seal trim strip 2 press seals on the upper strata of frame 1 support plate 11, heat absorbing sheet 5 is installed on lower floor's support plate 12 of frame 1, insulation gas-bearing formation 4 is between daylighting glass 3 and heat absorbing sheet 5, heat-insulation layer 7 is fixedly installed on the back side of heat absorbing sheet 5, it is characterized in that: post printing opacity thermal isolation film 8 at the back side of daylighting glass 3, space capsule thermal isolation film 9 is posted at the back side at the combination of heat absorbing sheet 5 and heat transfer medium pipe 6, sets up heat insulating strips 10 around frame 1 and insulation gas-bearing formation 4 are contacted.

Owing to post printing opacity thermal isolation film 8 at the back side of daylighting glass 3, space capsule thermal isolation film 9 has been sticked at the back side at the combination of heat absorbing sheet 5 and heat transfer medium pipe 6, at frame 1 and the insulation gas-bearing formation 4 contacted heat insulating strips 10 of setting up all around, the lost approach of the heat of flat-plate solar collector is effectively controlled, can reduce thermal loss significantly, thereby improve the heat absorption efficiency of flat type solar heat collector, through test determination, under equal experimental condition, the heat absorption efficiency comparison of the flat type solar heat collector of this low heat waste is according to improving 15%～20%.
