Description
Technical field:
The present invention relates to a kind of many materials rivet welding composite solar collector plate core, make mould and method.Belong to the solar water heater field.
Background technology:
Existing conventional flat plate collector plate core all is by the comb of two collectors, several vertical arrangements up and down; Mode through the manual work welding lets collector and comb interconnect, and forms a plate type solar heat collection plate core that is used for water conservancy diversion jointly; But owing to be to adopt artificial welding manner to connect; Require collector and comb must be homogeneous material, otherwise the weldability between different materials is poor, influences welding quality.So existing flat plate collector plate core is difficult to realize standardization, mechanization, automation, large-scale production,
In addition, can leave over down corrosion-resistant during the manual welding of aluminium collector plate core; Disadvantages such as copper aluminium crushing resistance compound and the copper coin core is poor, caliber is little, is prone to stop up, and the thermal conductivity of stainless steel collector plate core is bad.
Summary of the invention:
The objective of the invention is to overcome above-mentioned prior art; Invent a kind of can many materials rivet welding composite solar collector plate core and preparation method; It can with the mode of multiple material through riveting, weldering be combined into can bear running water high pressure, anti-corrosive properties good, be difficult for stopping up, the plate core of the solar thermal collector efficiently of good, the big latus rectum mozzle of thermal conductivity, Here it is probing direction of the present invention.
For the structure of many materials of the present invention rivet welding composite solar heat-collecting plate core is: by a upper header (1) and the parallel placement of a lower header (1); Several combs (2) have been parallel to each other about between upper header (1) and the lower header (1); Two collectors (1) interconnect the back with comb (2) and form a plate core of solar heat-collecting, it is characterized in that:
Several connecting holes (5) that on collector (1), keep at a certain distance away out, the edge of each connecting hole (5) have a circle groove, form connecting hole (5) the connection platform on a band stretching limit;
Every comb (2) end caliber size is less than comb (2) central tube barrel footpath size;
The internal diameter of connecting hole (5) and the external diameter of every comb (2) two ends pipeline are complementary in the every collector (1), and comb (2) end shape pipeline can be put in collector (1) connecting hole (5);
Every comb (2) two ends small diameter pipeline is put into the connecting hole (5) that upper header (1) and lower collector pipe (1) are left in advance respectively; Being tightly connected with the connecting hole (5) that riveted joint/bonding/welding manner will every comb (2) and two collectors (1) are with the stretching limit up and down is one, constitutes a solar thermal collector heat-collecting plate core (3).
The material of collector (1) and the available unlike material of comb (2), riveted joint becomes a solar thermal collector heat-absorbing plate core (3) admittedly.
Comb (2) both sides have absorber plate, aluminium sheet, the copper coin of absorber plate for handling through selectivity anodic oxidation, the blue film of plating or black chromium plating mode; Perhaps absorber plate is welded into collector plate core through laser or ultrasonic bonding mode and mozzle.
A kind of particular manufacturing craft of making many materials rivet welding composite solar collector plate core; It is characterized in that particular manufacturing craft is used for outer clamping and positioning mould that preliminary election clamps collector (1) external diameter, rivet clasp slide block (21) that is positioned over collector (1) inwall and a nose cone rivet clasp slide bar (30) formation by one
Outer clamping and positioning mould is made up of positioning module (13) under positioning module (12) on the semicircular arc and the semicircular arc, a compressor arm (11) is housed, a hole or the groove that matees with comb (2) external diameter that following positioning module (13) is opened on the last positioning module (12);
Rivet clasp slide block (21) is a hollow tubular; One end inwall of rivet clasp slide block (21) hollow pipe is the taper that outer end is big, the inner end is little (22), and the axial direction of conical inboard wall has several slits, and nose cone rivet clasp slide bar (30) can pass from the hollow pipe of rivet clasp slide block (21); Let the slit of hollow pipe end open; The outer wall of rivet clasp slide block (21) hollow pipe has convex module (23), projection external diameter in the convex module (23) and comb (2) internal diameter coupling
Nose cone rivet clasp slide bar (30) termination is cone shape (32), and cone shape (32) major diameter place connects large diameter cylinder (31), and it is small diameter cylinders shape (33) that cone shape (32) minor diameter connects.
Many materials rivet welding composite solar collector plate core preparation method is characterized in that whenever extruding a connecting hole (5) at a distance from a segment distance at collector (1) earlier connects platform, and has the connection aperture Φ A on band stretching limit in each connecting hole (5) corresponding position:
The connecting hole (5) of collector (1) is outside to be that Φ B pipeline is connected with the minor diameter of comb (2) end directly, constitutes a rivet clasp location structure, and convenient outer clamping and positioning mold cramping is fixed;
The minor diameter of connecting hole (5) inwall of collector (1) and comb (2) end is under small diameter cylinders shape (33) pulling function of Φ A pipeline in nose cone rivet clasp slide bar (30); Cone shape (32) in the nose cone rivet clasp slide bar (30) opens the slit of rivet clasp slide block (21) hollow pipe end; Outer wall convex module (23) moves down to be depressed; Thereby the minor diameter that makes outer wall convex module (23) push down comb (2) end (being preferably with the heatproof fluid sealant) is a Φ A pipeline; Let comb (2) end Φ A ducting side along flange, the mutual riveted and fixed of comb (2) end material and collector (1) connecting hole edge together.
Collector plate core of the present invention is to put into two collectors (1) hole up and down respectively by the two ends of several parallel longitudinals arrangements, metal comb; Through the riveted joint mode with the two ends of comb become with the collector riveted can bearing certain pressure (not causing the heat-transfer working medium seepage) water conservancy diversion use pipeline, as usefulness.
The present invention makes above-mentioned plate core of solar heat-collecting can use particular manufacturing craft, also can use other mode of matching of comb aperture in advance.
That the present invention has is simple in structure, ingenious, production efficiency is high; Solved effectively conventional collector plate core difficulty slip out of the hand worker welding, be difficult to realize the disadvantage of standardization, mechanization, automation, large-scale production; Left corrosion-resistant when having overcome full aluminium collector plate core manual welding, copper aluminium is compound and the crushing resistance copper coin core is poor, caliber is little short slabs such as (being prone to stop up) have prolonged service life of heat collector simultaneously; Especially after not adopting welding procedure; Can strengthen the latus rectum of collector and comb and reduce the wall thickness of these tubing; Promptly improve the trafficability characteristic of fluid and pressure-bearing property, the reduction product cost of mozzle; Make full use of the distinctive superior function of various materials self, be combined into the collector plate core of various different cost performances through the mode of riveting, weldering.It is practical, is a kind of novelty, suitable new product, and the plate core for flat-plate solar collector of extensive market prospects is arranged.
