Description
Technical field
The present invention relates to solar energy heat utilization device, refer in particular to a kind of solar energy air heat collector in conjunction with heat accumulating.Can be laid on the roof or be placed in the courtyard, night utilize heat accumulating to continue heat release from solar radiative absorption heat energy daytime, is reached for the purpose of housing heating or agricultural product drying.
Background technology
Flat type solar heat collector is an a kind of main mode of utilizing solar energy, is widely used in fields such as building heating, agricultural product drying.Existing solar plate air collector mainly is made up of transparent cover plate, absorber plate, insulation shell three parts.Although it is big that flat-plate collector receives the solar energy area, area of dissipation is also big.After absorber plate absorbed solar temperature rising, heat will be from the environment space of upper cover plate and base plate inflow lower temperature, so there is the shortcoming that heat loss is big, collecting efficiency is low.Present corrective measure mainly is to increase the transparent honeycomb structure between double-layer cover plate, thereby reduces the loss of heat from upper cover plate.But because flat-plate collector is difficult to utilize vacuum heat-insulating, heat loss is still greater than the electron tubes type heat collector, thereby needs further improvement.On the other hand, traditional solar energy air heat collector does not have heat accumulation function yet, can not work at night.
The example of existing flat solar heat collector as the utility model of number of patent application 85200928, is characterized as and has the air return flow line, has increased the path that air heats in heat collector.The utility model of number of patent application 88221059.9 (publication number 2042939U) and 93248208.2 (publication number 2193978Y) and for example, feature are settles the transparent honeycomb structure between transparent cover plate and absorber plate, thereby has reduced the heat loss of upper cover plate.And for example the patent of invention of number of patent application 03113079.8 (publication number CN1467457A) also is to adopt the transparent honeycomb structure to reduce the heat loss of upper cover plate, just makes common rectangular box into the reflection paraboloid body, has increased the absorption of heat.Above-mentioned patent working all has certain effect to the thermal efficiency that improves solar thermal collector, but they do not possess temperature control and heat accumulation function.
Summary of the invention
The present invention is a kind of solar energy air heat collector in conjunction with heat accumulating, it is between the absorber plate of traditional flat air collector and insulation base plate, fill heat accumulating, utilize heat accumulating to absorb and store unnecessary heat, thereby make solar energy air heat collector obtain two improvement: the one, because the maximum temperature of thermal-arrest plate is subjected to the restriction of heat accumulating phase transition temperature, can not rise so high, thereby reduce heat loss, improve the thermal efficiency; The 2nd, make solar thermal collector have the heat accumulation function simultaneously, prolonged the heating time of heat collector.
The present invention is characterized in that: heat collector is made up of double-deck transparent cover plate, honeycomb, the absorber plate that is coated with solar selective coat, the canister that is packaged with heat accumulating, casing five parts and the air inlet and outlet that insulation material is housed.Absorber plate is a V-structure, and itself and adjacent wall constitute air flow channel.The absorber plate top is a honeycomb, and the below is a heat accumulating, and honeycomb places between the double-deck transparent cover plate.They are placed in the insulation casing together, and the insulation casing is made up of metallic plate shell and insulation material.
Sunlight passes transparent cover plate and honeycomb shines on the absorber plate in the work, and absorber plate changes into heat energy with solar radiation, and the part of heat energy is used to add hot-air, and another part is absorbed by heat accumulating, and some loses by cover plate up and down.
In solar energy air heat collector, produce following effect behind the adding heat accumulating:
1. absorber plate is absorbed by heat accumulating from a large amount of heats of conversion of solar energy, thereby has reduced to pass through the thermal loss of cover plate up and down.
2. owing to adopt low-temperature phase-change material, the thermal-arrest plate temperature is limited in the transformation temperature of heat accumulating, and plate Wen Buhui heats up too high, makes the thermal-arrest plate and the temperature difference in the external world reduce, thereby has further reduced the loss of heat.
3. heat accumulating can continue to provide heat energy to the house after the sun sets, and has prolonged the use of heat collector.
4. can be placed on the roof easily or in the courtyard, absorb solar thermal energy.Simple in structure, installation and maintenance are easy.
Description of drawings
Fig. 1 is the structural representation in conjunction with the solar energy air heat collector of heat accumulating.Comprise that absorber plate, 5 that 1 double-deck transparent cover plate, 2 honeycombs, 3 air flow channels, 4 are coated with solar selective coat is packaged with canister, 6 insulation casings, 7 inlet of cold airs, 8 hot air outlets of heat accumulating.
The specific embodiment
Below in conjunction with Fig. 1, embodiments of the present invention are described further.
As shown in Figure 1, heat collector is made up of double-deck transparent cover plate 1, honeycomb 2, the absorber plate 4 that is coated with solar selective coat, casing 6 five parts that are packaged with the canister 5 of heat accumulating and insulation material is housed.Transparent cover plate and cellular material are Merlon or fiberglass, and absorber plate is galvanized sheet or aluminium sheet, and heat accumulating is low-temperature phase-change materials such as sal glauberi or paraffin, and insulation material is polyurethane or polystyrol foam material.Honeycomb 2 is the rectangle cell body, between double-deck transparent cover plate 1, works the thermal convection current effect that suppresses.Absorber plate 4 is a V-structure, and between lower floor's transparent cover plate and heat vessel, itself and adjacent wall constitute air flow channel 3, plays a part simultaneously to absorb solar radiation and add hot-air.It is in rectangle or the columniform thin canister 5 that heat accumulating is encapsulated in several long and narrow cross sections, melts back leakage and distortion to avoid its heat absorption.Canister 5 is placed side by side between absorber plate 4 and insulation base plate 6, and insulation casing 6 is made up of metallic plate shell and insulation material.
The solar thermal energy that absorber plate 4 is absorbed in the work, a part will directly heat from import 7 enter, V-arrangement air flow channel 3 slow flow air, heat taken to use the zone by exporting 8 by air.The heat energy of remainder is mainly to upper cover plate 1 and lower shoe 6 both direction transmission and be lost in the environment.The path of lower shoe is intercepted by phase-change heat-storage material because the existence that the canister 5 of heat accumulating is housed, heat are flowed through.When temperature was low, because the absorber plate and the external environment temperature difference are little, so the thermal loss of heat collector was little.When temperature continuation rising, when reaching transformation temperature, heat accumulating begins to melt, and absorbs a large amount of heats simultaneously and stores.All greatly reduce by the top transparent cover plate or the thermal loss of below base plate this moment, and after heat accumulating changed liquid state into fully, the heat collector temperature just may continue to raise.Therefore, the maximum temperature of heat collector will depend primarily on the phase transition temperature of heat accumulating.Because heat transmission mainly is subjected to the temperature difference influence of heat collector and external environment,, can reduces the temperature difference of heat collector and external environment, thereby reduce the heat loss of heat collector greatly by adopting low-temperature phase-change material.Night, heat accumulating began to solidify along with the reduction of temperature, discharged the heat that store daytime simultaneously.Thereby this heat collector has had the function of storing heat again.
