Fig. 3 is a cistern structure of the present utility model;
Wherein: 1. heat exchanger tube; 2. cement plate; 3. water pump; 4. warming plate; 5. cistern; The 6-water collecting and diversifying device; The 7-water intaking valve; The 8-outlet valve; 9 water bags.
Embodiment
Embodiment 1
As shown in Figure 1, adopt heat exchanger tube 1 as heat collector, heat exchanger tube 1 is provided with and is the U type, the heat that can guarantee water like this can be by fully heat exchange, U type thermal-collecting tube evenly is arranged in parallel together, be horizontally fixed on behind the greenhouse within the walls the surface and go up outlet pipeline and the inlet pipeline that its two ends connect water collecting and diversifying device 6 respectively, water collecting and diversifying device 6 plays the effect that moisture is flowed and compiles, the inlet pipeline of water collecting and diversifying device 6 is provided with water intaking valve 7 and is connected with water pump 3, water is annotated in the thermal-collecting tube, and the outlet pipeline of water collecting and diversifying device 6 is provided with outlet valve 8, is when greenhouse temperature is higher, water in the thermal-collecting tube can be discharged, reduce the greenhouse amount of stored heat.Heat exchanger tube 1 adopts the higher black plastic pipe of heat transfer coefficient, is satisfying under the pressure-bearing thinly as far as possible, can guarantee that like this heat-transfer effect is better; Be arranged on behind the greenhouse by solar heat near the wall underground as the cistern 5 of regenerative apparatus, as shown in Figure 3, in heat-accumulating process, lose heat too much for fear of cistern, around cistern 5 and the bottom one deck warming plate 4 is set, described warming plate 4 adopts perlites or heat transfer coefficient materials with smaller formation.And on cistern 5, cover cement plate 2.Water pump 3 is arranged in the cistern 5, opens water pump 3 when temperature is higher in the daytime greenhouse, and the water in the pond is recycled in the wall heat exchanger tube of back, absorbs solar radiation, and water temperature returns in the cistern 5 after raising; Like this heat of heat exchanger tube 1 collection on daytime being transferred to cistern 5 by water pump 3 stores, night is when greenhouse temperature is low, the ON cycle water pump 3 again, with the hot water circuit in the cistern 5 in heat exchanger tube 1, can reject heat to simultaneously in the greenhouse to increase greenhouse temperature, after the release heat, the water in the heat exchanger tube 1 returns in the cistern 5.
Embodiment 2
As shown in Figure 3, adopt water bag 9, can use rectangular water bag, be fixed on the position of being convenient to collect heat on the inner surface of wall behind the greenhouse as heat collector.Water bag 9 is connected on the water pump 3 by pipeline, water pump 3 is arranged in the cistern 5, the structure of cistern as shown in Figure 3, the mode of concrete accumulation of heat is with specific embodiment 1, by day the heat of water bag 9 collections being transferred to cistern 5 by water pump 3 stores, night is when greenhouse temperature is low, the ON cycle water pump 3 again, with the hot water circuit in the cistern 5 in water bag 9, can reject heat to simultaneously in the greenhouse to increase greenhouse temperature, after the release heat, the water in the heat exchanger tube 1 returns in the cistern 5.
Although disclose specific embodiment of the utility model and accompanying drawing for the purpose of illustration, its purpose is to help to understand content of the present utility model and implement according to this, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and appended claim, various replacements, variation and modification all are possible.The utility model should not be limited to this specification most preferred embodiment and the disclosed content of accompanying drawing, and the claimed scope of the utility model is as the criterion with the scope that claims define.
