Description
Technical field
The invention belongs to solar low-temperature heat utilization fields, and in particular to a kind of self-adapting solar energy flat plate collector.
Background technique
Freezing tolerance of the presently commercially available plate solar collector greatly most without self active, must before freezing in winter
Must take in advance hot water recharge heat preservation, low level discharge water emptying or compressed air blow by force the methods of sky come it is passive antifreeze.And it influences
The principal element of plate solar collector environmental suitability is its flow passage structure and composition material, at present plate solar thermal-arrest
The runner of device is mainly 3 kinds of tubular structures: perpendicular grid-type (III font of likeness in form), horizontal grid-type (three fonts of likeness in form), snake type (likeness in form S word
Type).First two runner form is the journeys such as typical multichannel parallel channel, is formed by copper collector and comb vertical welding,
Mechanical structure is complicated, and technique soldering opening is more, and institute's consumption material is also more, causes its high production cost, difficulty big, is also difficult to adapt to
The operating conditions such as rapid heat cycle, it is more difficult to adapt to extreme operating conditions and the climatic environments such as freeze proof icing.Snake type runner then belongs to a kind of single-pass
Road, too long in flow bend is excessive, causes its running resistance larger, and system dynamic role is poor, it is difficult to the sun of reform of nature circulation
The operation of energy balcony water heater system can not adapt to the climatic environments requirement such as freeze proof icing.In order to overcome these deficiencies, special to certainly
Plate solar collector is adapted to be researched and developed.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of self-adapting solar energy flat plate collector, it can be fitted automatically
Generated complex stress when answering the operating conditions such as rapid heat cycle, make it have jelly without splitting, the freeze proof and emergency capability of self active.
The technical solution used to solve the technical problems of the present invention is that: it includes frame and plate core, and plate core is mainly by collector
It is formed by connecting with comb, collector is fabricated from a flexible material, and comb is made of metal material, and collector extends collector and interrupts, comb
It injects collector and interrupts interior sealing therewith with merging and header in communication；The comb of same row is formed by two sections, two sections of combs by by
Continue pipe concatenation connection in made of flexible material；The nozzle for continuing pipe upper and lower ends in described connect with comb respectively, in continuous pipe
Be equipped with interlayer in tube wall, interlayer pass through in continue the pipeline of pipe and be connected to comb；The collector interrupt root outer surface be equipped with plus
Strong circular cone.The flow passage structure that the non-heat absorptivity such as collector is manufactured due to application flexibility material utilizes the good plasticity of flexible collector
Generated complexity when the operating conditions such as the swelling volume and tension when water freezes, and automatic adaptation rapid heat cycle is accommodated with elasticity
Stress, thus realize plate solar collector have freeze without splitting, the freeze proof and emergency capability of self active.
Further, the comb of same row is formed by two sections, and two sections of combs are by continuing pipe string in being fabricated from a flexible material
Lead in succession.Due to when the water in heat collector, which is endured cold, to freeze, comb is under glass cover-plate large area without guarantor because of thermal coefficient height
On the position of adiabator protection, comb is endured cold most fast earliest, and comb both ends are influenced and induction by heat reservoirs such as collectors, because
This, the water in plate core endure cold icing sequence be since among comb, to the collector at comb both ends spread.Under normal circumstances,
The water that the volume that water freezing is expanded can not also freeze at both ends squeezes away, to not generate excessive extrusion stress again, and in continue
The setting of pipe then accommodates the swelling volume and tension when water freezes using the good plasticity of pipe and elasticity is continued in flexibility, facilitates
Volume expansion is too fast when preventing water freezing, and the water at both ends is not squeezed away and leads to comb bursting by freezing.
Further, pipe is continued in there are two types of design method: the first be in continue the nozzle closings of pipe left and right ends, in continue
The tube wall of pipe respectively to upper and lower ends extend several connect one to one with comb in continue and interrupt；Another kind continues pipe in being
The nozzle of upper and lower ends is connect with comb respectively, in continue pipe tube wall in be equipped with interlayer, interlayer pass through in continue pipe pipeline and row
Pipe connection.It is related to mode for second, has enough intensity and comb sealing to cooperate to continue the nozzle of pipe in guarantee, preferably
Be at the top of interlayer and in continue between tube top portion, interlayer bottom and in continue be respectively solid engaging portion, each solid knot between bottom of the tube
The length L in conjunction portion continues the 1/4 of length of tube H in being not less than.
Further, the interrupt outer surface of root of the collector is equipped with and reinforces circular cone, and the setting for reinforcing circular cone facilitates
360 ° are improved collectors and interrupted the intensity of root, and collector is made to interrupt even intensity everywhere on root circle face.
Further, the collector is connected with auxiliary tube and cross under in turn, and cross under passes through the frame of heat collector, auxiliary
Pipe and cross under are made of flexible or plastic material.The setting of auxiliary tube helps to adjust plate solar according to the design needs
The position of the inlet and outlet of heat collector.Cross under is conducive to use with water storage box etc. mainly for the protection of collector and auxiliary tube
Hydrophone connection avoids collector and auxiliary tube because occurring to wear due to whole replacement with frame, to reduce maintenance cost.
Further, the length M that the collector is interrupted is greater than or equal to the outer diameter N of collector.Accordingly even when collector is by comb
Interior ice is squeezed to complete and is flattened, and also can guarantee that the deformation quantity of collector is less than the length that collector is interrupted, to guarantee comb and collection
Pipe, which is interrupted, keeps connection, without departing from.
In the technical program, interrupt to prevent comb to be detached from collector, they have following two connection type: one is combs
Both ends falling-resistant ring is equipped with by welding or jumping-up, falling-resistant ring inject collector interrupt in and be stuck in that collector is interrupted and collector mutually passes through
At mouthful, the setting of falling-resistant ring is beneficial to prevent comb from interior disengaging of interrupting.
The comb and collector interrupt between be equipped with insulation anti-avulsion bushing, insulation anti-avulsion bushing in tubular rivet shape and with collection
Pipe is interrupted riveting, and the setting of insulation anti-avulsion bushing not only contributes to prevent comb from interior disengaging of interrupting, and effectively avoids because of row
The high temperature heat of the metal surface of pipe be transferred directly to collector interrupt and cause collector to be interrupted deformation occurs and accelerated ageing.
