As preferably, the cross section of described thermal-collecting tube 38 is squares.
Traditional heat collector is all that thermal-collecting tube is set directly in focus, once position is offset, heat just can thermal-arrest in thermal-collecting tube, pass through said structure, solar light irradiation is at speculum 37, reflex to tube plate structure by speculum 37, by heat thermal-arrest in the thermal-collecting tube 38 in tube plate structure. By this structure, even because install or operation problem causes tube plate structure position to change, solar energy still can thermal-arrest in thermal-collecting tube 38, thereby avoid thermal loss; Simultaneously because traditional heat collector is all that thermal-collecting tube is set directly in focus, cause thermal-collecting tube hot-spot, cause thermal-collecting tube local losses excessive, life-span is too short, even cause thermal-collecting tube over-heat inside, produce superheated steam, be full of whole thermal-collecting tube, cause thermal-collecting tube internal pressure excessive, damage thermal-collecting tube, and take the application's structure, both heat can be absorbed fully, again can be by dispersion relative heat, avoid heat too concentrated, make overall thermal-collecting tube heat absorption evenly, extend the service life of thermal-collecting tube.
As one preferably, the focus D of speculum 37 is positioned on the mid point of two tube plate structure least significant end lines. By above-mentioned setting, can ensure to absorb to the full extent solar energy, avoid solar energy to lose because of focal shift, can also ensure that platy structure may reduce the sunlight on speculum 37 that is radiated at blocking as far as possible simultaneously. Prove by experiment, adopt said structure, the effect of solar absorption is best.
As preferably, the cross-sectional area of thermal-collecting tube is not identical. Along the middle part (being extreme higher position) of tube plate structure, on both sides extreme lower position (being that Fig. 3 thermal-collecting tube A is to B, C direction) bearing of trend, the cross-sectional area of thermal-collecting tube is increasing. In experiment, find, extend to both sides from middle part, caloric receptivity raises gradually, is because there be stopping of tube plate structure by analyzing main cause, causes middle part to be heated minimum, and extends from middle part to both sides, absorbs heat and raises gradually. Continuous change by thermal-collecting tube cross-sectional area is large, can increase the discharge of bottom, can make being heated evenly of water in whole thermal-collecting tube, avoids both sides excess Temperature and medium temperature is too low. The material of the thermal-collecting tube in the middle of so also can avoiding at high temperature easily damages, and can keep the temperature of whole thermal-collecting tube even, increases the service life.
As preferably, along the middle part (being extreme higher position) of tube plate structure, on both sides extreme lower position (being that Fig. 3 thermal-collecting tube A is to B, C direction) bearing of trend, the amplitude that thermal-collecting tube cross-sectional area increases diminishes gradually. In experiment, find, for caloric receptivity, successively decreasing gradually to the amplification on both sides extreme lower position (being that Fig. 2 thermal-collecting tube A is to B, C direction) bearing of trend in middle part (being extreme higher position) along tube plate structure, therefore caliber has been done to variation like this, to meet corresponding requirement.

As preferably, on the lower wall surface of tube plate structure (face relative with speculum 37), be provided for the projection of augmentation of heat transfer, to strengthen the absorption to solar energy. Along the middle part (being extreme higher position) of tube plate structure, on both sides extreme lower position (being that Fig. 3 thermal-collecting tube A is to B, C direction) bearing of trend, the height of projection of the lower wall surface of thermal-collecting tube 38 is more and more higher. In experiment, find, extend to both sides from middle part, caloric receptivity raises gradually, is because there be stopping of tube plate structure by analyzing main cause, causes middle part to be heated minimum, and extends from middle part to both sides, absorbs heat and raises gradually. By the continuous rising of height of projection, can make being heated evenly of water in whole thermal-collecting tube 38, avoid both sides excess Temperature and medium temperature is too low. The material of the thermal-collecting tube in the middle of so also can avoiding at high temperature easily damages, and can keep the temperature of whole thermal-collecting tube even, increases the service life.
As preferably, along the link position (being the middle part of tube plate structure) of two tube plate structures to both sides (being that Fig. 3 thermal-collecting tube A is to B, C direction) extend, the density of protrusions of the lower wall surface of thermal-collecting tube 38 is more and more higher. Main cause is heated minimum in the middle part of being, and extends from middle part to both sides, absorbs heat and raises gradually. By the continuous rising of density of protrusions, can make being heated evenly of water in whole thermal-collecting tube 38, avoid the too low and both sides excess Temperature of medium temperature. The material of the thermal-collecting tube 38 in the middle of so also can avoiding at high temperature easily damages, and can keep the temperature of whole thermal-collecting tube even, increases the service life.
As preferably, the outer wall of thermal-collecting tube 38 can arrange outer fin, straight fins or helical fin for example can be set, the outer fin height difference of different thermal-collecting tubes, along link position (being the middle part of tube plate structure) (being that Fig. 3 thermal-collecting tube A is to B, C direction) extension to both sides of two tube plate structures, the height of outer fin reduces gradually.

By inner fin 40 is set, thermal-collecting tube 38 inside are divided into multiple passage aisles 42, further augmentation of heat transfer, but the mobile pressure of corresponding fluid increases. By intercommunicating pore 41 is set, ensure the connection between adjacent passage aisle 42, thereby the fluid in passage aisle that pressure is large can be flowed in the passage aisle little to contiguous pressure, solve each problem that small flow channels 27 pressure are inhomogeneous and local pressure is excessive of inside of condensation end, thereby promote fluid fully flowing in heat exchanger channels, simultaneously by the setting of intercommunicating pore 27, also reduced the pressure of thermal-collecting tube inside, improve heat exchange efficiency, the service life of also having improved thermal-collecting tube simultaneously.

Because along the flow direction of thermal-collecting tube 38 inner fluids, the constantly even evaporation of heat absorption of fluid in thermal-collecting tube 38, therefore make the pressure of thermal-collecting tube constantly increase, and because the existence of intercommunicating pore 41, make the pressure distribution of thermal-collecting tube 38 inside more and more even, therefore the area of intercommunicating pore needs very large, it is large by continuous change is set, thereby make ensureing that inside heat pipe pressure is all even pressure in the situation that, variation by intercommunicating pore area increases heat exchange area, thereby improves heat exchange efficiency.
Preferably, along the flow direction of thermal-collecting tube 38 inner fluids, the amplitude that the area of described intercommunicating pore 41 constantly increases constantly increases. By setting like this, be also the Changing Pattern that meets flowing pressure, when further reducing flow resistance, improve heat exchange efficiency. By setting like this, by being the heat exchange efficiency that experiment finds to improve 9% left and right, resistance remains unchanged substantially simultaneously.

Distribution Principle by above-mentioned quantity is identical with area minimizing principle, and compare identical with intercommunicating pore quantity, reduces circulation area by distributed number.
In actual experiment, find, the area of intercommunicating pore 41 can not be too small, and too small words can cause the increase of flow resistance, thereby cause weakening of heat exchange, and the area of intercommunicating pore 41 can not be excessive, and area is excessive, can cause the minimizing of heat exchange area, thereby reduce heat transfer effect. Equally, the cross-sectional area of thermal-collecting tube 38 can not be excessive, and the excessive thermal-collecting tube that distributes in tube plate structure unit length of causing is very few, cause equally heat transfer effect variation, thermal-collecting tube flow area can not be too small, and too small meeting causes flow resistance to increase, thereby causes heat transfer effect variation. Therefore the distance between intercommunicating pore 41 and thermal-collecting tube cross-sectional area and adjacent intercommunicating pore 41 thereof must meet certain requirements.
Therefore, the present invention is by thousands of numerical simulations of the heat collector of multiple different sizes and test data, meeting in industrial requirements pressure-bearing situation (below 10MPa), in the situation that realizing maximum heat exchange amount, the dimensionally-optimised relation of the best heat collector summing up.
