Technical field
Helioplant technical field is the utility model is related to, specifically, is related to a kind of multi-chamber vacuum solar
Can heat collector.
Background technology
Existing solar thermal collector generally includes glass shell, forms closing chamber in glass shell, is set in closing chamber
Collecting core is equipped with, collecting core is made of copper, aluminium, stainless steel and other metal materials, and collecting core is connected to the conductive fluid outside closing chamber
Metal is responsible for, and closing chamber vacuumizes, heat-insulated to realize, collecting core and the end junction sealing of glass closing chamber connect.It is existing
This solar thermal collector structure, closing chamber is a big chamber, internal parallel or is in series with more conductive fluid gold
Belong to branch pipe.Because the overall volume of closing chamber is big, it is big to vacuumize difficulty, and easy gas leakage, therefore is relatively difficult to ensure the height of card closing chamber
Vacuum, and vacuumize that rear pressure-bearing is larger, overall closing chamber bearing capacity is poor, not enough firmly, is easily broken.
Further, since collecting core is made up of metal material, metal material is different from the coefficient of expansion of glass, in solar energy collection
When hot device absorbs solar energy expanded by heating, collecting core is different from the degrees of expansion of glass shell, can cause outside collecting core and glass
The sealing junction of shell produces crack gas leakage, the vacuum moment of closing chamber is lost sky, loses vacuum heat-insulation effect, cause solar energy
The overall service life of heat collector is shorter.

Two sub-chamber.
Preferably, getter is provided with the sub-chamber.
Preferably, the row being equipped with each sub-chamber for being vacuumized to the sub-chamber is corresponded on the glass shell
Valve.
Preferably, one end of the glass shell is provided with opening, and described metal-cored one end sets the metal supervisor, institute
The one end for stating glass plate is connected or is welded to connect by the opening sealing of the glass head seal block and the glass shell.
Preferably, the both ends of the glass shell are respectively equipped with opening, and the metal-cored both ends are respectively equipped with metal master
Pipe, the both ends of the glass plate respectively by the connection of the both ends open of the glass head seal block and glass shell sealing or
It is welded to connect.
After employing above-mentioned technical proposal, the beneficial effects of the utility model are：
Multi-chamber evacuated solar collector of the present utility model, accommodating chamber include at least two mutually completely cut off divide chamber
Room, the structure of this multi-cavity, minimize each sub-chamber, sound construction, bearing capacity are strong, it is not easy to be broken because pressure is big
Split, be easy to vacuumize, it is not easy to which sky is lost in gas leakage, improves vacuum.
Multi-chamber evacuated solar collector of the present utility model, metal manifold are sealed in glass plate, the glass plate
Surface be provided with absorption film；The end set glass head seal block of glass plate, glass head seal block and glass shell sealing connection closing
Sub-chamber.Such a structure of multi-chamber evacuated solar collector, it is metal-cored to be wrapped in glass plate, make outside metal-cored and glass
Vacuum space in shell is completely isolated, and identical with the material of glass shell with the glass plate of glass shell opening connection, together
Belonging to glass material, the coefficient of expansion is identical, when solar thermal collector absorbs solar energy expanded by heating, the parcel glass plate of collecting core
It is identical with the degrees of expansion of glass shell, make the parcel glass plate of collecting core and with degree heat expansion is cold the junction of glass shell
Contracting, it is not easy to produce crack gas leakage, and be wrapped in due to metal-cored in glass plate, made metal-cored empty with vacuum in glass shell
Between it is completely isolated, it is metal-cored with the junction of glass plate because crack caused by expansion does not interfere with the vacuum of vacuum chamber yet,
Avoid because degrees of expansion difference causes the vacuum moment of closing chamber to lose the problem of empty, extend making for solar thermal collector entirety
Use the life-span.In addition, metal-cored sealing makes metal-cored to be not easy to snap and deform in glass plate.
