The specific embodiment
Please refer to Fig. 1, it is a kind of glass heat pipe heat collector that is applicable to pressure-bearing type solar water heater that the utility model provides, it has two working medium pipelines 8 that are communicated to this water heater, and having a plurality of glass heat pipes 7, the heat transfer block 9 by a metal material (as copper or aluminium) between each glass heat pipe 7 and this two working medium pipelines 8 links together.
Shown in Figure 1A, Figure 1B, it is the structural representation of above-mentioned heat transfer block 9, this heat transfer block 9 is made up of working medium connecting portion 91 and heat pipe connecting portion 92 that one connects, in the present embodiment, this working medium connecting portion 91 is rectangular-shaped, and offer two working medium connecting holes 911 that run through, this heat pipe connecting portion 92 is cylindric, it is provided with a heat pipe connecting hole 921 that runs through along central shaft, and this working medium connecting hole 911 and this heat pipe connecting hole 921 mutually noninterfere spatially, be set to the best with orthogonal direction.When heat collector is assembled, working medium connecting hole 911 backs that these two working medium pipelines 8 pass a plurality of heat transfer blocks 9 successively form circulation, the heat pipe connecting hole 921 of each heat transfer block 9 connects the condensation end 701 of a glass heat pipe 7 again, glass heat pipe 7 collected solar energy can be delivered in this working medium pipeline 8 by this heat transfer block 9, by the circulating of working medium, solar energy is delivered in the water heater then.
As shown in Figure 1, for fear of the condensation end 701 of glass heat pipe 7 in the heat pipe connecting hole 921 of the heat transfer block 9 of metal material owing to fragmentation takes place for extruding, collision, can also between the heat pipe connecting hole 921 of the condensation end 701 of glass heat pipe 7 and this heat transfer block 9, a heat transmission fin 10 be set.Shown in Fig. 1 C, Fig. 1 D, this heat transmission fin 10 is metal material (as copper or an aluminium), is folded into polygon prism shape by sheet, and in each folding seamed edge position of this prism, the part outwards is provided with a projection arc 101.When the condensation end 701 of glass heat pipe 7 inserts in the heat pipe connecting hole 921 of these heat transfer blocks 9, the projection arc 101 of this heat transmission fin 10 and the inwall butt of this heat pipe connecting hole 921, these heat transmission fin 10 inwalls then with condensation end 701 butts of this glass heat pipe 7, owing to this heat transmission fin 10 is that sheet metal has elasticity, it is more moderate that this elasticity makes that glass heat pipe 7 and heat transfer block 9 contact dynamics, both guaranteed that the thermal resistance between glass heat pipe 7 and the heat transfer block 9 was less, and can avoid glass heat pipe 7 that broken situation takes place again.
Above-mentioned heat transmission fin 10 can by the elasticity fin 11 of metal material (as copper or aluminium) replacement.As Fig. 1 E, shown in Fig. 1 F, it is the shape of cross section schematic diagram of this elasticity fin 11, and these elasticity fin 11 user mode schematic diagrames, as can be known, this elasticity fin 11 has an interior ring 111 that does not seal (about 330～350 degree of central angle), two free ends of ring 111 all stretch out in being somebody's turn to do, be extended with an external annulus 112 then respectively in the opposite direction, the central angle of each external annulus 112 is about 150～170 degree, and it is parallel with ring 111 in this substantially, also has certain clearance between external annulus 112 and the interior ring 111, in the stage casing of this external annulus 112 and the end V-arrangement flanging 113 that bent inwards respectively.When the condensation end 701 of glass heat pipe 7 inserts in the heat pipe connecting hole 921 of these heat transfer blocks 9, two external annulus 112 of this elasticity fin 11 and the inwall butt of this heat pipe connecting hole 921, condensation end 701 butts of 111 of the interior rings of this elasticity fin 11 and this glass heat pipe 7, simultaneously because extraneous compression, V-arrangement flanging 113 on this external annulus 112 can with ring 111 butts in this, because this elasticity fin 11 is metal materials, the drift angle of this V-arrangement flanging 113 can open or dwindle and have elasticity, it is more moderate that this elasticity makes that glass heat pipe 7 and heat transfer block 9 contact dynamics, both guaranteed that the thermal resistance between glass heat pipe 7 and the heat transfer block 9 was less, and can avoid glass heat pipe 7 that broken situation takes place again.
Refer again to Fig. 2 A, Fig. 2 B, this heat transfer block 9 can be made integrative-structure with heat transmission fin 10, become a flexible fins 13, this flexible fins 13 is one-body molded by metal (as copper or aluminium) thin plate, its manufacture process is to cut a plurality of paired parallel short sides earlier on thin plate, with instrument the metal between the parallel short sides is squeezed to this thin plate one thruster then and form a plurality of bridge sheets 922, then with the upset of this thin plate one end and with the stacked pressing of the other end to form this working medium connecting portion 91, part between the thin plate two ends then is wound into a cylinder, this cylinder constitutes this heat pipe connecting portion 92, these working medium connecting portion 91 upper punches are pressed with two these working medium connecting holes 911, be used for wearing connection for two working medium pipelines 8, give prominence to the inside on this cylinder (i.e. this heat pipe connecting portion 92) and be provided with a plurality of bridge sheets 922, this bridge sheet 922 is the arch bridge shape, and two ends of the bridge are connected with this cylinder one, and the both sides of bridge then are separated with this cylinder, this bridge sheet 922 is used for closely contacting broken pipe when avoiding pegging graft with the condensation end 701 of glass heat pipe 7.
With reference to Fig. 2 C, it is the schematic cross-section of the another kind of molding structure of cylinder (instant heating pipe jointing part 92) of flexible fins 13, the surface of this cylinder is by compression molding, its surface is evenly distributed with many concave arcs 923 to outer process, each concave arc 923 is extending axially along this cylinder all, when the condensation end 701 of glass heat pipe 7 inserts in the heat pipe connecting portion 92, because flexible fins is the elastic telescopic effect of thin plate and projection arc 923, cylinder inner wall will fully closely contact with condensation end, guarantee to reduce thermal resistance, and broken pipe when avoiding pegging graft.
More than explanation is just illustrative for the utility model; and nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited; can make many modifications, variation or equivalence, but all will fall within the protection domain of the present utility model.
