Embodiment
The present invention is further described below in conjunction with accompanying drawing：
A kind of direct changing type antifreezing heat-collecting plate as shown in Figure 1 to Figure 3, including：Frame 1, bottom plate 2, heat-insulation layer 3, the and of thermal-arrest component 4
Glass cover-plate 5, the bottom plate 1 and glass cover-plate 5 are connected with the frame 1 respectively surrounds airtight cavity, the He of thermal-arrest component 4
Heat-insulation layer 3 is arranged in airtight cavity, and the thermal-arrest component 4 includes hollow super heat-conductive pipe 41 and is completely encapsulated in super heat-conductive pipe
The thermal-arrest wing plate 42 on 41 surfaces, the inside of the super heat-conductive pipe 41 are provided with superconducting fluid, described in a stretching of the super heat-conductive pipe 41
Frame 1.
The heat-insulation layer 3 is filled in the inner side of the frame 1 and the top of the bottom plate；Heat-insulation layer 3 is to be integrally formed
, seam is not present in the part of the inner side of frame 1 and the top of bottom plate 2, and its sealing property and heat-insulating property are further lifted.
The surface of the heat-insulation layer 3 is also covered with an aluminium foil layer 31, and the top of aluminium foil layer 31 is additionally provided with rock wool layer 32, institute
State the top that super heat-conductive pipe 41 is arranged on the rock wool layer 32；Aluminium foil layer 31 and rock wool layer 32 strengthen the insulation inside collecting plate
Effect, further strengthen the ability that thermal-arrest component 4 absorbs heat.
The material of the super heat-conductive pipe 41 is copper alloy；Copper alloy is the splendid metallic conductor of thermal conductivity, can accelerate heat
Pass to efficiency.
The super heat-conductive pipe 41 includes heat exchanging part 411 and thermal-arrest portion 412, and the heat exchanging part 411 is the stretching frame 1
One, the diameter of the cross section of heat exchanging part 411 is more than the diameter in thermal-arrest portion 412；The superconduction that the inside of super heat-conductive pipe 41 is set
Liquid evaporates after the enough heats of collecting plate absorbed inside and reaches the heat exchanging part 411 of super heat-conductive pipe 41, by heat exchanging part 411
Diameter to do be to increase heat exchange area greatly so that superconducting fluid steam is accelerated with the heat transfer rate inside water tank.
When in use, heat exchanging part 411 will be extend into inside water tank the present embodiment, and be entered with the water in inner bag inside water tank
Row heat exchange, to carry out encapsulation process herein certainly, mainly be sealed with silica gel sealing ring etc.；When having have illumination daytime
In the case of, through glass cover-plate irradiation thermal-arrest wing plate 42, thermal-arrest wing plate 42 absorbs heat and transfers heat to heat superconducting for illumination
Within pipe 41, superconducting fluid is become into gaseous state from liquid after the absorption heat of super heat-conductive pipe 41, gaseous superconducting fluid rises to heat exchanging part
With the water direct heat-exchange inside water tank, it need not be connected between collecting plate and water tank by pipeline, user is anti-without periodically addition
Freeze liquid, save the cost of later stage maintenance, the heat exchange efficiency of whole system also substantially increases in addition；Inside collecting plate
Pipeline need not be set, and without water inlet and delivery port is set at frame 1, the sealing of collecting plate and heat insulation effect are more preferably.
A kind of production technology of direct changing type antifreezing heat-collecting plate, comprises the following steps：
（1）By frame billot by being machined to the frame 1 of rectangle without riveting riveting so that the face ring of frame 1 four is closed, and corner is without connecing
Mouthful；The production method of frame 1 of script is by rivet by rivet by four billots, and is sealed at riveting
Processing, this production method cause the poor sealing performance of frame 1, the inside of the frame 1 easily water inlet if outdoor exposure for a long time, existing
Change its production technology, the face ring of frame 1 four is closed, and sealing property is greatly improved, and script seam crossing is also more flat than original
It is sliding.
（2）Bottom plate 2 is placed in frame 1, and it is direct toward the inwall of frame 1 and the top of bottom plate 2 by foaming machine
Filled polyurethane heat-insulation layer 3；The part that the heat-insulation layer 3 of script is located above scuncheon and bottom plate be it is split type, it is indirectly
Seam, heat-insulating property is bad, now cause by the way of foaming machine is directly filled the one of heat-insulation layer 3 at frame 1 and bottom plate 2 into
Type, no longer seam between the inner side of frame 1 and the top of bottom plate 2, heat-insulating property is more preferably.
（3）Aluminium foil layer 31 is laid on to the upper surface of heat-insulation layer 3, rock wool layer 32 is placed on to the upper surface of aluminium foil layer 31；
Aluminium foil layer 31 and rock wool layer 32 strengthen the heat insulation effect inside collecting plate, further strengthen the energy that thermal-arrest component 4 absorbs heat
Power.
（4）As shown in Figure 4 and Figure 5, super heat-conductive pipe 41 is plugged in the hollow tube among thermal-arrest wing plate 42, then by group
The thermal-arrest component 4 installed is placed on the lower section of pressing machine, and thermal-arrest wing plate 42 and super heat-conductive pipe 41 are pressed together on into one by pressing machine
Rise, the inwall of the hollow tube of thermal-arrest wing plate 42 is completely encapsulated in the surface of super heat-conductive pipe 41；The technique of script is the side by spot welding
Thermal-arrest wing plate 42 is welded on the surface of super heat-conductive pipe 41 by formula, although this mode cost is low, thermal-arrest wing plate 42 and super heat-conductive pipe 41
Between do not contact fully, heat transfer effect is poor, and heat loss is serious, the structure of traditional thermal-arrest wing plate 42 is now changed, in thermal-arrest
Siphunculus in being set among wing plate 42, super heat-conductive pipe are plugged in middle siphunculus, by way of pressing machine pressing that middle siphunculus is tight
The surface of super heat-conductive pipe 41 is pressed in, fully contacts between thermal-arrest wing plate 42 and super heat-conductive pipe 41, is conducted heat by way of heat transfer,
The forfeiture of heat is reduced, heat transfer effect is splendid.
（5）The thermal-arrest component for completing processing is arranged in frame, heat exchanging part 411 is stretched by the through hole opened up at frame 1
Go out outside frame, the through hole of frame 1 sets sealing ring to carry out encapsulation process；Inside the collecting plate of traditional solar water heater all
Heat exchanging water pipe can be provided with, and water inlet and delivery port with external pipeline communication are provided with frame, due to the insulation of collecting plate
Effect is poor, is first exchanged heat from collecting plate, is then back to water tank by pipeline again, this process heat loss is big；Now change
The structure of collecting plate, does not set heat exchanging water pipe inside collecting plate, and the heat exchanging part of super heat-conductive pipe is directly inserted into inside water tank, with
The inner bag direct heat transfer of water tank, the problem of reducing open piping heat loss, heat conduction efficiency greatly improves.
（6）Glass cover-plate lid 5 is located at the upper surface of frame 1 and glass cover-plate 5 is fixed on frame 1 by press strip
Surface.
Using new manufacturing process, the connecting port on frame 1 is reduced, and heat-insulation layer 3 is integral-filled using foaming machine
Mode, monoblock collecting plate are without riveting mouth so that the sealing and heat-insulating property of collecting plate obtain huge improvement, heat funeral
Lose and reduce, heat exchange efficiency is greatly enhanced.
Described above to be not intended to limit the scope of the present invention, all foundation the technology of the present invention are substantially to the above
Any modification, equivalent variations and the modification that embodiment is made, in the range of still falling within technical scheme.
