Description
Technical field
The utility model relates to a kind of heat-releasing device that holds that is applicable to the greenhouse, and particularly a kind of device that in the greenhouse, initiatively holds heat release belongs to the agricultural engineering technology field.
Background technology
The maximum characteristics of greenhouse by solar heat are that energy is almost all from solar radiation.Daytime, solar radiation behind the greenhouse, promptly with the stored in form of heat in body of wall and soil; At night, when indoor air temperature descended, the heat of accumulating in body of wall and the soil was again continuously to the greenhouse supply.But because this exothermic process that holds is a kind of passive mode that depends on greenhouse structure, the heat storage capacity of body of wall and soil is limited, and the low temperature phenomenon happens occasionally, and influences the output and the benefit of chamber crop.The utility model is intended to design a kind of heat-releasing device that initiatively holds, the mode absorption solar radiant heat as much as possible that accumulate through active daytime, and carry out the release of heat according to temperature in the greenhouse and crop demand night, to improve the greenhouse nocturnal temperature.
The utility model content
The utility model designed a kind of be applicable to greenhouse temperature increasing initiatively hold heat-releasing device, the heat that solar radiation produced with greenhouse daytime as much as possible is accumulated, and is used for the heating at night.
For realizing above-mentioned purpose, the utility model has adopted following technical scheme:
A kind of heat-releasing device that holds that is applicable to the greenhouse comprises water inlet pipe, thermal-arrest plate, collector pipe, heat storage water tank and water pump, and wherein thermal-arrest plate upper end is equipped with water inlet pipe, and the lower end is equipped with collector pipe; Heat storage water tank one end connects water pump and water inlet pipe successively, and the other end connects collector pipe.
Further, the said heat-releasing device that holds comprises a support, and said thermal-arrest plate tilts to be fixed on this support top, and the angle of inclination is 30 to spend to 50 degree.
Further, said thermal-arrest plate comprises a recuperation layer and a hyaline layer.
Further, said recuperation layer comprises heat-sink shell and heat-insulation layer, and said heat-sink shell is between hyaline layer and heat-insulation layer.
Further, said heat-sink shell is a black film, and said heat-insulation layer is a styrofoam, and said hyaline layer is a lucite.
Further, be covered with insulation material around the said heat storage water tank.
Further, said insulation material is a styrofoam.
Further, said water inlet pipe is the pvc pipe that has the slit.
Further, said collector pipe is semi-circular pipe fitting, and thermal-arrest plate lower end places the opening of said semicircle pipe fitting.
The utility model through initiatively hold the exoergic device; The mode absorption solar radiant heat as much as possible that daytime, realization was accumulated; Carry out the release of heat according to indoor temperature and crop demand night, to improve the greenhouse temperature at night, realizes heat circulating collection and storage.
The advantage of the utility model is:
With solar energy as thermal source, any fossil fuel that need not burn can not produce any pollution; With water as heat storage medium, with low cost; 3. the hot water of being accumulated also can be used as irrigation water, increases the crop root zone temperature.
