Background technology
Along with the renewable new forms of energy of aggravation of energy crisis are valued by the people gradually, particularly solar energy is as a kind of clean energy resource, and utilize convenient, to friendly features such as the degree of dependence of environment are less, therefore start by the development and utilization that gets more and more.It is the Major Difficulties that utilizes solar energy that energy disperses to be difficult for Collection and use efficiency not high always.Existing solar thermal collector transfers heat to the heat-conducting mediums such as water by the irradiation of the sun, because the radiation heat loss of flat-plate solar heat collector is large and a part of light reflection is scattered and disappeared and do not utilize, and figure layer absorption efficiency is not high, thereby has caused the efficiency of flat-plate solar heat collector lower.
Summary of the invention
The technical problem that the utility model solves is the deficiency that overcomes existing existence, for example, and part light reflection when the large and light of radiation heat loss irradiates on absorber and the deficiency do not utilized.The utility model provides simplicity of design, and, utilize and catoptrically reduce radiation heat loss's and reach a kind of novel solar collector of high thermal efficiency simultaneously.
The utility model is achieved in that a kind of novel solar collector is mainly comprised of housing, heat-preservation cotton, U-shaped pipe, water tank, heat pipe, heat absorption floor, transparent cover plate, water inlet pipe and outlet pipe.Its water tank is hydrostatic column, and water tank is in heat collector upper end horizontal positioned, and two U-shaped pipes are inserted in respectively water tank two ends, and there are water inlet pipe and outlet pipe in water tank one end.Because water tank is inserted at U-shaped pipe two ends, so water can circulate in water tank and U-shaped pipe.Heat pipe two ends are inserted in respectively in a side pipe of two U-shaped pipes through U-shaped tube wall.Heat pipe is the material that heat transfer property is good, with good two the heat absorption floors of material of conductivity of heat, is fixed on a heat pipe and forms V font groove.Heat absorption floor fixing on two adjacent heat pipes forms W connected in star.Except heat-absorbent surface, all the other heat pipes, water tank, U-shaped pipe and the absorber plate back side are surrounded by heat-preservation cotton, and are contained in housing, and the positive heat absorption of housing floor upper end is covered by transparent cover plate, and transparent cover plate is fixed on housing.User's cold water flows to water tank from water inlet pipe, then flows out from outlet pipe.
When ray cast arrives heat collector top, light projects heat absorption floor through transparent cover plate.The part light Surface absorption that absorbed heat is converted to heat energy, and unabsorbed light reflexes to opposite side heat absorption floor and again absorbs and be converted to heat energy.Heat energy heats the water in U-shaped pipe by heat pipe.Thereby improve the thermal absorptivity of absorber.
When heat absorption floor surface temperature raises, its radiation heat loss also increases.The heat-absorbent surface designing due to the utility model is V font groove shape, so the radiant heat Journalistic of any is absorbed to the opposite side heat absorption floor of V font groove on heat absorption floor surface.Thereby reduced the radiation heat loss of heat collector.
In the utility model, adopt two U-shaped pipes simultaneously, thereby improved the heat transfer rate between water and heat pipe, and integral body reduces heat pipe and the floor temperature of absorbing heat, reduced the heat loss of heat collector.
When the angle of V font groove more hour, improve heat-absorbent surface thermal absorptivity, reduce radiation heat loss.
The utlity model has following advantage: design is new, and owing to adopting adopting heat pipes for heat transfer in the middle of heat collector, thereby this collector structure is simple.In the middle of this heat collector, adopt two U-shaped pipes, strengthened the heat transfer rate of heat pipe and water, reduced heat pipe and heat absorption floor temperature, reduced the heat loss of heat collector.Meanwhile, adopt V font absorber, thereby improved the thermal efficiency of heat collector.

The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the utility model protection domain is not limit therewith.
A kind of novel solar collector is mainly by housing 1, heat-preservation cotton 2, U-shaped pipe 3, water tank 4, heat pipe 5, heat absorption floor 6, transparent cover plate 7, water inlet pipe 8 and outlet pipe 9.Its water tank 4 is hydrostatic columns, and water tank 4 is in heat collector upper end horizontal positioned, and two U-shaped pipes 3 are inserted in respectively water tank 4 two ends, and there are water inlet pipe 8 and outlet pipe 9 in water tank 4 one end.Because water tank 4 is inserted at U-shaped pipe 3 two ends, so water can circulate in water tank 4 and U-shaped pipe 3.Heat pipe 5 two ends are inserted in respectively in a side pipe of two U-shaped pipes 3 through U-shaped pipe 3 tube walls.Heat pipe 5 is materials that heat transfer property is good, with good two the heat absorption floors 6 of material of conductivity of heat, is fixed on a heat pipe 5 and forms V font groove.Heat absorption floor 6 fixing on two adjacent heat pipes 5 forms W connected in star.Except heat-absorbent surface, all the other U-shaped pipes 3, water tank 4, heat pipe 5 and heat absorption floor 6 back sides are surrounded by heat-preservation cotton 2, and are contained in housing 1, and the positive heat absorption of housing 1 floor 6 upper ends are covered by transparent cover plate 7, and transparent cover plate 7 is fixed on housing 1.User's cold water flows to water tank 4 from water inlet pipe 8, then flows out from outlet pipe 9.
When ray cast arrives heat collector top, light projects heat absorption floor 6 through transparent cover plate 7.The part light Surface absorption that absorbed heat is converted to heat energy, and unabsorbed light reflexes to opposite side heat absorption floor 6 and again absorbs and be converted to heat energy.Heat energy is by the water in heat pipe 5 heating U-shaped pipes 3.Thereby improve the thermal absorptivity of absorber.
When heat absorption floor 6 surface temperatures raise, its radiation heat loss also increases.Because the heat-absorbent surface of the utility model design is V font groove shape, so upper any the radiant heat Journalistic in heat absorption floor 6 surfaces is absorbed to the opposite side of the V font groove floor 6 that absorbs heat.Thereby reduced the radiation heat loss of heat collector.
In the middle of the utility model, adopt two U-shaped pipes 3 simultaneously, thereby improved the heat transfer rate between water and heat pipe 5, and integral body reduces heat pipe 5 and floor 7 temperature of absorbing heat, reduced the heat loss of heat collector.
When the angle of V font groove more hour, improve heat-absorbent surface thermal absorptivity, reduce radiation heat loss.
Job description: because heat-absorbent surface in the utility model is W connected in star, when ray cast arrives heat collector top, light projects heat absorption floor 6 through transparent cover plate 7, and part light is absorbed and is converted to heat energy, and unabsorbed part light reflexes to opposite side heat absorption floor 6 and again absorbs and be converted to heat energy.On heat-absorbent surface, the radiant heat Journalistic of any absorbs to opposite side heat absorption floor 6 simultaneously.The heat energy of heat absorption floor 6 carries out heat exchange by heat pipe 5 and the water in U-shaped pipe 3.Due to U-shaped pipe 3 two ends and water tank 4 UNICOMs, and there is heat pipe 5 in a side pipe of U-shaped pipe 3, so cold water flows to from the opposite side of U-shaped pipe 3 the heat intensification that U-shaped pipe 3 absorbs heat pipe 5, because water temperature rising density diminishes, so water forms Natural Circulation between water tank 4 and U-shaped pipe 3, the water that heating water tank is 4 li.User's cold water flows to water tank 4 from water inlet pipe 8, and hot water flows out from outlet pipe 9.
Owing to adopting two U-shaped pipes 3 in the middle of the utility model, thereby improved the heat transfer rate between water and heat pipe 5, and integral body reduces heat pipe 5 and floor 6 temperature of absorbing heat, reduced the heat loss of heat collector.
