Description
Technical field
The utility model is a kind of heat-exchange system, more particularly to a kind of soil thermal storage and heat pipe heat convection system.
Background technology
In all kinds of facilities of agricultural, heliogreenhouse is as China's original creation greenhouse, with its energy-efficient performance advantage,
By the support energetically and popularization of country, it is widely used in agricultural production.But China's traditional agriculture greenhouse generally existing
Daytime is utilized conventional because by solar radiation temperature indoor temperature is too high, nocturnal temperature relatively low the problems such as influenceing crop growth
Energy sources for heating temperature room air, can largely consume energy, and traditional heliogreenhouse can not meet the needs of agriculture energy-saving and emission-reduction development.
Heat storage is used as by epigeosphere soil, 47% solar energy up to earth's surface can be absorbed to, equivalent to 500 times of mankind's power consumption.
Species on greenhouse heating system mainly has：Electrical heating heats, coal burning heating, heat pump heating.It is wherein hot
Pump heating is divided into air source heat pump heating, Heating by Ground Source Heat Pump etc. again.Electric heating system is relatively simple, and initial cost is smaller,
But greenhouse institute calorific requirement is larger, the electricity needed for electric heating system is larger, and required energy cost is higher during utilization, and increase is thrown
It is higher to enter cost fruits and vegetables price, is unfavorable for market sale；The operating cost of coal burning heating system is relatively low, but fire coal can be made
Into the pollution of environment, in the case where common people increasingly focus on air quality, the overall background of energy-saving and emission-reduction, coal-fired heating system is step by step
It is eliminated；Heat pump heat distribution system can realize the target more saved, but mainly come in the season of cold, the thermal source of heat pump
From the air of external environment condition or the soil of underground, the temperature of thermal source is relatively low, and this situation causes the heating technology to heat pump
And performance requirement is higher, the cost of heat pump also uprises therewith.
Utility model content
The utility model mainly solves the deficiencies in the prior art, there is provided one kind, which proposes, uses air as load
Thermal medium, for soil as method of the heat storage medium to greenhouse heating, hot-air is pumped into underground piping through blower fan in daytime greenhouse, leads to
The heat exchange of underground piping and soil is crossed, heat is transmitted to soil storage；Night, there will be the heat in soil by thermal diode
Amount slowly release, so that warm room air keeps constant temperature.When temperature is too low in night greenhouse, system is by automatic start heat two
Pole pipe, the heat of underground storage take on the ground, to improve temperature in canopy, the patent realize energy " deposit ight day, it is fine to deposit
The moon is used ", it has been truly realized a kind of soil thermal storage and heat pipe heat convection system of energy-saving and emission-reduction.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：

Without capillary UNICOM between thermal diode body, the night soil moisture is higher than warmhouse booth air themperature, closes blower fan, liquid trap
Device formula thermal diode starts positive work, and liquid trap and evaporator section are together heated, and the coagulating liq of their internal reservoirs steams
Send out and enter the circulation of heat pipe tube core, heat pipe tube core is in the normal operating conditions of high heat conductance, the heat that will be stored in soil
It is discharged into warmhouse booth, realizes environment temperature needed for the growth of plant night；
（2）, liquid trap formula thermal diode reverse operation when：
Daytime, sunshine was radiated on warmhouse booth so that indoor temperature raises, and causes warm Indoor Temperature after irradiating for a long time
Height is spent, at this moment opens breeze fan, hot-air is sent into radiating pipe laying in parallel by hot-air induced duct, carried out with soil
Heat exchange, heat is stored in soil, now heat pipe tube core starts opposite direction work, and heat pipe tube core upper end is changed into heating
Section, the lower end placed into the soil are changed into condensation end, are gradually accumulated in after steam condensation in liquid trap, due to liquid trap
Without capillary UNICOM between device and liquid trap formula thermal diode body, therefore accumulate in liquid trap can not be again for condensation water
It is back to evaporator section to be circulated, gradually dries up so as to the working medium of bringing-up section, heat pipe tube core, which turns into an only a small amount of tube wall, leads
The hollow circular-tube of heat, realize reverse heat transfer and block；When the night soil moisture is higher than warmhouse booth air themperature, continue heat
Pipe circulates.
The greenhouse is ground greenhouse, and wherein ABCD is warmhouse booth ground, AEFB-CDHG greenhouse walls, remaining
Face is transparent, light-passing plastic, and crops are planted on ABCD warmhouse booths ground, or carries out soilless culture.Accumulation of heat pipeline connects
Heat supply main pipeline is connected to, heat supply main pipeline passes vertically through described soil horizon and is connected with heat absorption blower fan, and heat absorption blower fan is by canopy
In air suction heat supply main pipeline.Radiating tube in parallel is embedded to warmhouse booth soil thermostat layer, while is also embedded to heat pipe vertically
Soil thermostat layer, condensation end then radiate more than warmhouse booth ground to air.
The material of parallel connection radiating pipe laying is polyvinyl chloride（PVC）.
Evaporator section is scattered in liquid trap formula thermal diode is embedded in around radiating pipe laying in parallel, with more preferable and soil
Exchanged heat.
Hot-air is sent into underground by assembling in warmhouse booth, by hot-air induced duct.
The condensation end of liquid trap formula thermal diode is higher by warmhouse booth ground in air, while its condensation end
Fin is installed to be easy to preferably be exchanged heat with air, and crops of soilless culture etc. can be laid on fin.
Liquid trap formula thermal diode, it is excellent in positive heat transfer property, and reversely only as caused by pipe axial wall
A small amount of leakage heat.
Wherein there is tube core in evaporator section, adiabatic section and condensation segment pipe, and do not connected with liquid trap capillary so that heat
Pipe reverse operation is suppressed, and daytime does not damage the heat in warmhouse booth.
Therefore, a kind of soil thermal storage provided by the utility model and heat pipe heat convection system, it is simple in construction, ensure soil
Temperature, be advantageous to plant growth, effectively reach energy-saving effect.
