As shown in Figure 1, a kind of photo-thermal constant temperature agricultural greenhouse comprising heat sink body 1, solar thermal collector 2, transparent membrane
3 and transparent panel 4.
The heat sink body 1 includes the first cooling fin 101, the second cooling fin 102 and oblique cooling fin 103, wherein first dissipates
Backing 101 and the second cooling fin 102 are vertically fixed on soil, that is to say, that the height extending direction of the first cooling fin 101 and
The height extending direction of second cooling fin 102 is vertical with soil surface.102 phase of first cooling fin 101 and the second cooling fin
It is mutually parallel, and first cooling fin 101 is higher than second cooling fin 102.
Oblique cooling fin 103 be arranged in the top of the first cooling fin 101 and the second cooling fin 102 and with the first cooling fin 101
It is connected with the second cooling fin 102.The side of the oblique cooling fin 103 is connected with the top of the first cooling fin 101, the other side and the
The top of two cooling fins 102 is connected.Since the first cooling fin 101 is higher than the second cooling fin 102, the oblique cooling fin 103 is tilted
In soil surface, as shown in Figure 1, the oblique cooling fin 103 and soil surface angle at an acute angle, the oblique cooling fin 103 and soil table
Angle between face is preferably between 30 °~75 °, to ensure that the firm in structure of heat sink body 1.
First cooling fin 101, the second cooling fin 102 and oblique cooling fin 103, three is connected, so that heat sink body 1 is
Integrated formed structure, it is more sturdy and durable.
First cooling fin 101, the second cooling fin 102 and oblique cooling fin 103 are radiators, and steel heating can be selected
Any one of piece, copper aluminium radiator, aluminium radiator.
The setting of solar thermal collector 2 is on soil surface and close to second cooling fin 102.Heat sink body 1 and solar energy
The thermally conductive connection of heat collector 2.
The solar thermal collector 2 is connected with the first cooling fin 101, the second cooling fin 102 and oblique cooling fin 103 respectively,
It is transmitted on heat sink body 1 to which thermal energy caused by solar radiation will be absorbed, then is come out heat by heat sink body 1.
In addition to this, solar thermal collector 2 also may be selected to be connected with the second cooling fin 102, heat caused by the solar thermal collector 2
It can be first transmitted to the second cooling fin 102, then heat is sequentially delivered to oblique cooling fin 103, the first cooling fin 101, passes through heat dissipation
Main body 1 comes out heat.
Transparent membrane 3 is located at outside the heat sink body 1 and the solar thermal collector 2, side and first heat dissipation

Constant temperature in canopy.
Flat-plate solar heat collector or vacuum tube type solar energy heat collector can be selected in the solar thermal collector 2.
When flat-plate solar heat collector works, after solar radiation passes through transparent cover plate, it is incident upon on absorber plate, is absorbed heat
Plate absorbs and is converted to thermal energy, the heat-transfer working medium being then passed in absorber plate, increases the temperature of heat-transfer working medium, as thermal-arrest
The useful energy of device exports；At the same time, the absorber plate after temperature increases will inevitably pass through conduction, convection current and radiation etc.
Mode radiates around, becomes the thermal loss of heat collector.
Flat plate solar collector is a kind of most basic type in solar heat collector, structure is simple, it is reliable for operation, at
This is suitable for also having the characteristics that bearing capacity is strong, endotherm area is big.
Vacuum tube type solar energy heat collector is exactly the solar energy that the space between absorber and cover transparent sheet is evacuated
Heat collector.
Vacuum tube presses absorber material category, can be divided into two classes: one kind is glass absorber vacuum tube (or for full glass
Vacuum tube), one kind is metal absorber vacuum tube (or being glass-metal vacuum tube).Heat pipe type vacuum pipe is metal heat absorption
One kind of body vacuum tube, it is made of main components such as heat pipe, absorber, glass tube and metal ends.
Vacuum tube type solar energy heat collector has the advantages that following irreplaceable:
Resistance to frost: using anti-freezing type heat pipe, will not bursting by freezing under -50 DEG C of severe cold condition.
Starting is fast: the thermal capacity of heat pipe is big, in the sun can quantity of heat given up after a few minutes.
Above-mentioned photo-thermal constant temperature agricultural greenhouse, which employs 4 couple structures of transparent membrane 3 and transparent panel, and pass through the sun
Energy heat collector 2 will absorb thermal energy caused by solar radiation and will be dispersed into greenhouse by heat sink body 1, ensure that the perseverance in greenhouse
Temperature enables crops inside greenhouse normally to grow, and does not need additionally to save expense, also to environment using other energy
It is pollution-free.
With improvement, the transparent membrane 3 is preferably multi-layer transparent film, to further enhance the heat insulating ability of greenhouse
Can,
With being further improved, the side on the oblique cooling fin 103 backwards to soil surface is densely covered with black micelle 5, black
Substance has heat absorption capacity very strongly, can further promote greenhouse itself by the black micelle 5 that oblique 103 surface of cooling fin is gathered
Heat absorption capacity, being more conducive to crops inside greenhouse can normally grow.
It is above that certain exemplary embodiments of the utility model are only described by way of explanation, undoubtedly, for
Those skilled in the art can be with a variety of different without departing from the spirit and scope of the utility model
Mode is modified described embodiment.Therefore, above-mentioned attached drawing and description are regarded as illustrative in nature, and should not be construed as
Limitation to the utility model claims protection scope.
