B, C direction) on bearing of trend, the amplitude that thermal-collecting tube cross-sectional area increases tapers into.Find in an experiment, for heat absorption
Amount, along the middle part (i.e. extreme higher position) of tube plate structure to both sides extreme lower position (i.e. Fig. 2 thermal-collecting tube A is to B, C direction) extension side
Amplification upwards is gradually successively decreased, and therefore caliber has done such change, to meet corresponding requirement.
As preferably, maximum cross-sectional area is less than 1.22 with the ratio of minimum cross-sectional area.
As preferably, the lower wall surface (face relative with reflecting mirror 17) of tube plate structure is provided for the convex of augmentation of heat transfer
Rise, to strengthen the absorption to solar energy.Along tube plate structure middle part (i.e. extreme higher position) to both sides extreme lower position (i.e. Fig. 2 collect
Heat pipe A is to B, C direction) on bearing of trend, the height of projection of the lower wall surface of thermal-collecting tube 18 is more and more higher.Find in an experiment, from
Middle part extends to both sides, and caloric receptivity gradually rises, and is because the stop of tube plate structure by analyzing main cause, causes middle part
It is heated minimum, and extends to both sides from middle part, absorb heat and gradually rise.By the continuous rising of height of projection, can make
Being heated evenly of water in whole thermal-collecting tube 18, it is to avoid both sides temperature is too high and medium temperature is too low.In so can also avoiding
Between the material of thermal-collecting tube be at high temperature easily damaged, the homogeneous temperature of whole thermal-collecting tube can be kept, extend and use the longevity

Pipe A is to B, C direction) extend, the density of protrusions of the lower wall surface of thermal-collecting tube 18 is more and more higher.Main cause be middle part be heated minimum,
And extend to both sides from middle part, absorb heat and gradually rise.By the continuous rising of density of protrusions, so that whole thermal-arrest
In pipe 18, water is heated evenly, it is to avoid medium temperature is too low and both sides temperature is too high.So can also avoid the thermal-collecting tube of centre
The material of 18 is at high temperature easily damaged, and can keep the homogeneous temperature of whole thermal-collecting tube, increase the service life.

Radius constantly increases.
Because the flow direction of fluid in thermal-collecting tube 18, the fluid in thermal-collecting tube 18 constantly absorbs heat and even evaporates,
Hence in so that the pressure of thermal-collecting tube constantly increases, and because the existence of intercommunicating pore 26 so that the pressure within thermal-collecting tube 18
Distribution is more and more uniform, and therefore the area of intercommunicating pore needs very big, constantly becomes big by arranging, so that ensureing heat pipe
In the case of the most even pressure of internal pressure, increase heat exchange area by the change of intercommunicating pore area, thus improve heat exchange effect
Rate.
Preferably, the flow direction of fluid in thermal-collecting tube 18, the width that the area of described intercommunicating pore 26 constantly increases
Degree is continuously increased.By being arranged such, also it is the Changing Pattern meeting flowing pressure, while reducing flow resistance further,
Improve heat exchange efficiency.By being arranged such, by being to test the heat exchange efficiency finding to improve about 9%, resistance is basic simultaneously
Keep constant.
Preferably, the flow direction of fluid in thermal-collecting tube 18, the distributed quantity of intercommunicating pore 26 gets more and more, further
Preferably, the amplitude that described intercommunicating pore quantity 26 constantly increases is continuously increased.
Reduce principle by the Distribution Principle of above-mentioned quantity and area identical, identical with intercommunicating pore quantity compared with, logical
Cross distributed number to reduce circulation area.
Finding in actual experiment, the area of intercommunicating pore 26 can not be too small, too small if can cause the increase of flow resistance,
Thus causing weakening of heat exchange, the area of intercommunicating pore 26 can not be excessive, and area is excessive, can cause the minimizing of heat exchange area, thus
Reduce heat transfer effect.Equally, the cross-sectional area of thermal-collecting tube 18 can not be excessive, excessive causes in tube plate structure unit length distribution
Heat exchanger tube is very few, again results in heat transfer effect and is deteriorated, and thermal-collecting tube flow area can not be too small, and too small meeting causes flow resistance to increase
Add, thus cause heat transfer effect to be deteriorated.Therefore between intercommunicating pore 26 with thermal-collecting tube cross-sectional area and adjacent intercommunicating pore 26 thereof
Distance must is fulfilled for certain requirement.
Therefore, the present invention is thousands of the numerical simulations by multiple various sizes of heat collectors and test data,
