Along with improving constantly of people life and Production requirement, conventional energy resource day by day reduces and environmental pollution increases sharply.Now, the heat utilization of sunshine, as developing in the world nearly ten years the swiftest and the most violent renewable energy technologies, is clearly classified as " 12 " development in science and technology emphasis.At present, the utilization of solar thermal collector is more and more general.Conventional is flat metal heat collector and ceramic heat collector, and the topmost parts of heat collector are heat-collecting plate cores.The quality of the power of the corrosion resistance of heat-collecting plate core, the length in life-span, characteristic, is directly determining quality and the use cost of whole heat collector.That collector metal plate core conducts heat is fast, efficiency is high, but be easily corroded, aging fast, water quality easily polluted; And ceramic heat collecting plate core waterproof, do not seep water, burn into is not aging, but its intensity difference, rigidity weak, conduct heat slow.
The Tan Yongwei of China has invented a kind of solar thermal collector (patent No.: 200910051691.7), it comprises water inlet manifold, outfall sewer, is connected to many heat transmission copper pipes between water inlet manifold and outfall sewer and is connected to the heat absorbing fins on heat transmission copper pipe, this invention improves the object of collector power, collector area and heat-collecting capacity are effectively increased, but heat-collecting plate core is made up of copper pipe, cost is high, not corrosion-resistant, aging fast.The Chen Chong of China has invented a kind of collecting plate (patent No.: 201310031836.3) of plate solar collector, this invention heat-collecting plate core is made up of aluminium alloy, though corrosion-resistant, cost is low, the reflection of heat-collecting plate core light is not stronger, heat utilization ratio is not high.The JinWeiDong of China, Wang Wenhu have invented ceramic base material heat-absorbing plate core and the flat-plate solar collector (patent No.: 201310433298.0) thereof that a kind of cost is low, heat absorption capacity is good, this invention heat collector has not that burn into is not aging, the feature such as do not seep water, but ceramic base material relative intensity a little less than, in the time installing or use for a long time, easily cause plate core to break.
Summary of the invention
Object of the present invention aims to provide that a kind of intensity is high, good rigidly, life-span are grown, do not seep water, not solar energy pottery-metal composite energy storage heat-collecting plate core and the heat collector thereof of low, the operation convenient and flexible installation of burn into cost, to overcome deficiency of the prior art.
First the present invention provides a kind of pottery-metal composite energy storage heat-collecting plate core, this heat-collecting plate core comprises the heat collecting chamber being made up of black pottery heat absorption upper substrate (2) and black pottery heat absorption infrabasal plate (3), in heat collecting chamber, be provided with metal heat-conducting tube (4), the two ends of metal heat-conducting tube (4) connect respectively the water inlet (6) and the delivery port (7) that in heat collecting chamber, arrange, and metal heat-conducting tube (4) surrounding in heat collecting chamber forms air energy-storage layer (5).
Described water inlet (6) and delivery port (7) are made snakelike heat pipe taking aluminium alloy as material, be nested in the heat collecting chamber of black pottery heat absorption upper substrate (2) and infrabasal plate (3) composition.
Described black pottery heat absorption upper substrate surface is provided with the heat absorbing coating (1) of high-absorbility, antiradar reflectivity.
The present invention provides a kind of solar thermal collector that uses the above pottery-metal composite energy storage heat-collecting plate core simultaneously, this heat collector comprises the pottery-metal composite energy storage heat-collecting plate core described in, heat-collecting plate core top is provided with clear glass cover plate (10), heat-collecting plate core below is provided with thermal baffle layer (9), between the clear glass cover plate (10) of heat-collecting plate core and top, form air layer (11), between the thermal baffle layer (9) of heat-collecting plate core and below, form air energy-storage thermal-insulating layer (8).Described air layer (11) is provided with through hole (12) with the engagement edge of casing (14).
Advantage of the present invention and beneficial effect:
Advantage of the present invention and beneficial effect show following several respects:
1,, by changing material and the composition structure of traditional heat-collecting plate core, make that a kind of intensity is high, good rigidly, life-span are grown, do not seep water, the low solar thermal collector of burn into cost not.
2, by changing the structure of heat collector entirety, improve the optical energy utilization efficiency of heat collector.
3, device is in the structure of heat-collecting plate core and heat collector, air energy-storage layer and air energy-storage thermal-insulating layer are increased respectively, when the temperature of heat-conducting medium in metal heat-conducting tube lower than air energy-storage layer in when the temperature of air, heat imports heat-conducting medium into by air, when the temperature of heat-collecting plate core is during lower than the temperature of air energy-storage thermal-insulating layer, heat imports the heat-conducting medium in heat-collecting plate core into by air energy-storage thermal-insulating layer, has improved heat utilization rate.
