As preferably, the flow direction of fluid in thermal-collecting tube 1, the distance between adjacent communicating pipe 2 constantly reduces.
This is in order that arrange more communicating pipe, because along with the flowing of fluid, fluid is constantly heated, along with fluid is constantly heated, being heated in different thermal-collecting tubes is more and more uneven, therefore by above-mentioned setting, it is possible to ensure to reach as soon as possible pressure equilibrium in process fluid flow.
As preferably, along the flow direction of thermal-arrest tube fluid, the ever-reduced amplitude of distance between adjacent communicating pipe is increasing.
It is found through experiments, above-mentioned setting, it is possible to ensure more excellent in process fluid flow to reach pressure equilibrium faster.

As preferably, as it is shown on figure 3, the cross section of described thermal-collecting tube 1 is rhombus.
Although Fig. 3 does not show communicating pipe 2, but as preferred structure, the embodiment of the diamond structure thermal-collecting tube of Fig. 3 also includes communicating pipe 2.
As preferably, the line at two relative angles in described rhombus is perpendicular to transparent cover plate 4.
By arranging diamond structure thermal-collecting tube 1 and thermal-collecting tube 1 is set to the line at two relative angles being perpendicular to transparent cover plate 4, it is ensured that more surfaces of collector tubes can absorb solar energy such that it is able to makes full use of solar energy.
As preferably, each lens 3 are in two sections of settings, including tilting section 31 and 31. Described tilting section 31 and 32 extends along two limits on the top of rhombus, as shown in Figure 4.
By such setting, it is ensured that can the solar energy of thermal-arrest multiple directions, as shown in Figure 4, thus reaching to make full use of solar energy.
As preferably, the focus of described tilting section 31 and 32 is positioned at the intersection point of two diagonal angle lines of rhombus.
As preferably, the four edges of rhombus is equal, and four angles of rhombus are equal.

Described inner fin 7 is divided into multiple passage aisle 9 by internal for thermal-collecting tube 1, arranges intercommunicating pore 8, so that adjacent passage aisle 9 communicates with each other on inner fin.
By arranging inner fin 7, it is divided into multiple passage aisle 9, further augmentation of heat transfer by internal for thermal-collecting tube 1, but the pressure of corresponding fluid flowing increases. By arranging intercommunicating pore 8, ensure the connection between adjacent passage aisle 9, so that fluid in the big passage aisle of pressure can to flowing in the little passage aisle of contiguous pressure, solve each problem that small flow channels 9 pressure is uneven and local pressure is excessive of inside of condensation end, thus having promoted the fluid abundant flowing in heat exchanger channels, simultaneously by the setting of intercommunicating pore 8, also reduce the pressure within thermal-collecting tube, improve heat exchange efficiency, also improve the service life of thermal-collecting tube simultaneously.
Preferably, the flow direction of fluid in thermal-collecting tube 1, the area of described intercommunicating pore 8 constantly increases.
Described intercommunicating pore 8 is circular configuration, and the flow direction of fluid in thermal-collecting tube 1, the radius of described circular configuration constantly increases.
Because the flow direction of fluid in thermal-collecting tube 1, fluid in thermal-collecting tube 1 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 8 so that the pressure distribution within thermal-collecting tube 1 is more and more uniform, and therefore the area of intercommunicating pore needs very big, constantly become big by arranging, so that when ensureing inside heat pipe pressure all even pressure, increase heat exchange area by the change of intercommunicating pore area, thus improving heat exchange efficiency.
Preferably, the flow direction of fluid in thermal-collecting tube 1, the amplitude that the area of described intercommunicating pore 8 constantly increases is continuously increased. By such setting, also it is consistent with the Changing Pattern of flowing pressure, reduces while flow resistance further, improve heat exchange efficiency. By such setting, by being test it is found that the heat exchange efficiency of raising about 9%, resistance is held essentially constant simultaneously.
Preferably, the flow direction of fluid in thermal-collecting tube 1, the distributed quantity of intercommunicating pore 8 gets more and more, it is preferred that, the amplitude that described intercommunicating pore quantity constantly increases is continuously increased.
Reduce principle by the Distribution Principle of above-mentioned quantity with area identical, compared with identical with intercommunicating pore quantity, reduce circulation area by distributed number.
Finding in actual experiment, the area of intercommunicating pore 8 can not be too small, and too small words can cause the increase of flow resistance, thus causing weakening of heat exchange, the area of intercommunicating pore 8 can not be excessive, and area is excessive, can cause the minimizing of heat exchange area, thus reducing heat transfer effect. Equally, the cross-sectional area of thermal-collecting tube 1 can not be excessive, and the excessive heat exchanger tube causing being distributed in tube plate structure unit length is very few, again result in heat transfer effect to be deteriorated, thermal-collecting tube flow area can not be too small, and too small meeting causes that flow resistance increases, thus causing that heat transfer effect is deteriorated. Therefore the distance between intercommunicating pore 8 with thermal-collecting tube cross-sectional area and adjacent intercommunicating pore 8 thereof must is fulfilled for certain requirement.

Described pressure gauge 10 is connected to thermal-collecting tube 1, by measuring the pressure in thermal-collecting tube 1, check whether thermal-collecting tube 1 leaks, once leak, then the measurement data of pressure gauge 10 will be abnormal, then close the Fluid valve entered in thermal-collecting tube 1 in time.
As preferably, described heat collector also includes control system and valve, and described control system and valve carry out data cube computation, for controlling the opening and closing of valve and the size of valve flow. Described control system and pressure gauge 10 carry out data cube computation, for detecting the pressure that pressure gauge 10 is measured. Once the pressure of the pressure gauge 10 of control system detection is lower than predetermined value, then show pressure anomaly, it is likely that thermal-collecting tube 1 leaks, now control system control valve door and be automatically switched off, forbid that fluid flows in thermal-collecting tube. By above-mentioned automatic control function so that monitoring process realizes automatization.

So can reduce the quantity of pressure gauge 10, only by the pressure gauge that or quantity are few, thus realizing the pressure detecting of all thermal-collecting tubes.
As preferably, described fluid first passes through the inlet header of thermal-collecting tube, then passes through inlet header and enters each thermal-collecting tube 1. Described valve is arranged on fluid and enters on the pipeline of inlet header. So in time leakage being detected, automatic-closing valve, then fluid cannot be introduced into inlet header, naturally cannot be introduced into thermal-collecting tube.
As preferably, it is vacuum structure in casing 5.
As preferably, the pressure on thermal-collecting tube 1 top is measured in described pressure gauge 10. Mainly in running, top is usually steam condition, and pressure is maximum. Once leak, pressure change is obvious, so measurement is the most accurate.
