The heating fluid is formed, and the phase-converted fluid is filled in the collector tube box 8, each of which includes a circular arc-shaped plurality of heat pipe 7, and the end of the adjacent heat pipe 7 communicates with the plurality of heat pipes 7. The series structure, and causes the end of the heat pipe 7 to form a free end 3-6; the collecting tube box includes a first juice 10 and a second pipe 13, and the first pipe 10 is connected to the inlet of the left heat pipe group 11. The second tube 13 is connected to the inlet of the right increasing tube set 12, the outlet of the left heat pipe group 11 is connected to the left upper tube 21, and the exit of the right charge pipe group 12 is connected to the right upper tube 22; the first junction 10 and the second pipe 13 is disposed on the side of the collecting tube box 8. As a preferred, the left discharge pipe group 11 and the right amphippoint group 12 are symmetrical along the intermediate position of the collecting tube box.

[0045]As a preferred, the left upper tube 21, the right upper tube 22, and the heat pipe group 1 are disposed in the casing 9, and the flowing fluid is provided in the casing 9, the fluid, preferably air or water.

[0047]Preferably, the fluid flows in the horizontal direction.

[0048]Preferably, a plurality of exothermic tube groups 1 extending in the horizontal direction of the collecting tube box 8 along the left upper tube 21, and a parallel structure between the extension pipe group 1.

[0049]Preferably, the left upper tube 21 is provided with a left return tube 14 between the collector tube box 8, and the right upper tube 22 is provided with a right return tube 15 between the collecting tube box 8. Preferably, the return tube is disposed at both ends of the collector tube 8.

[0050]The collecting fluid is filled in the collector tube box 8, preferably a vapor phase transverse fluid. The fluid is heat evaporation in the collecting tube box 8, flowing along the exothermic tubular bundle to the left upper left tube 21, the right upper tube 22 flows, the fluid is thermally charged, thereby forming a vapor, and the volume of steam is much greater than water, thus formed Steam will flow in the coil for fast impact flow. Because the volume expansion and the flow of steam can induce the free end of the venting tube to generate vibration, the heat transfer pipe free ends during vibration, the vibration is transferred to the heat exchange fluid in the casing 9, and the fluid will also generate disturbances. Thereby, the surrounding heat exchange fluid is formed to form a spoiler, the boundary layer, thereby achieving the purpose of strengthening heat transfer. The fluid is reflowed to the collector tank by reflow tube after condensation of the fluid.

[0051]By modifying the prior art, the present invention is provided to two of the upper housing and the exothermic tube set to the left and right distribution, so that the exothermic pipe group distributed left and right sides can vibrate heat transfer, thereby expand the heat exchange vibration.

[0155]Of course, the hydraulic pump is also a very mature technology in the prior art.Figure 7The embodiment is simply a simple introduction, not limiting. All hydraulic pumps in the prior art can be used.

[0156]Descaling time is preferably carried out after a solar collector runs for a period of time. It is preferably carried out when the collecting effect is deteriorated.

[0157]As a preferred, the exothermic tube of the left heat pipe set is a central distribution at the axis of the upper left tube, and the exothermic tube of the right increasing tube set is a central distribution of the axis of the right tube. By setting the left and right tabs to a center, it can better ensure the distribution of the heat pipe, so that vibration and heat are uniform.

[0161]Preferably, the left discharge heat pipe group 11 and the right radius set 12 are missed in the horizontal extension direction, such asFigure 5 Indicated. Through the missed distribution, vibration and descaling can be made on different lengths, so that the vibration is more uniform, and the heat exchange and descaling effect can be enhanced.

[0162]Preferably, a mirror 16 is provided at a lower portion of the collecting device, and the collecting heat pipe box is located at the focus position of the mirror 16, where the left heat pipe group and the right increasing heat pipe group are located in the fluid passage. Thereby a solar collector system is formed.

[0163]Preferably, the support member 17, the support member 17 supports the heat collecting device.

[0164]Preferably, a fluid passage flows in a fluid channel. As shown in FIG. 2, the collecting heat pipe box 8 is located at the lower end of the fluid passage, as shown in FIG. Left upper tube 21, the right upper tube 22, the left heat pipe group 11 and the right amphip stopper set 12 are disposed in the fluid passage, by exothermic fluid in the heating fluid passage.

[0165]Preferably, the flow direction of the fluid is the same as the left upper tube 21, and the right upper tube 22 is the same as the direction in which the collecting tube box 8 is extended. By this setting, the fluid is blown in the flow of the heat transfer pipe group, especially the free end of the exothermic tube set, so that the free end vibrates, thereby strengthening heat transfer to achieve descaling.

[0166]Preferably, the fluid tube set 1 (e.g., on the left or right side)) is provided along the flow direction of the fluid in the fluid passage, along the flow direction of the fluid in the fluid passage, and heat Group 1 (eg, the diameter of the same side (left or right) is constantly large.

[0167]Along the flow direction of the fluid, the fluid temperature is constantly increasing, thereby constantly reduced the temperature of the heat transfer temperature, and the heat transfer capacity is getting larger. By becoming the diameter of the heat-insulating tube, more steam can be ensured to enter the exothermic tube set in the upper portion, ensuring that the fluid flow direction, because the vapor is large and the vibration effect is good, so that the overall heat is uniform. The distribution of steam in all exothermic tube groups is uniform, further strengthened the heat transfer effect, so that the overall vibration effect is uniform, the heat transfer effect is increased, and further improve the heat exchange effect and the descaling effect.

[0168]Preferably, the radial heat pipe group (e.g., such as one side (left or right side) is constantly increasing, along the flow direction of the fluid in the fluid in the fluid channel.

[0169]By this setting, the fluid is avoided to heat exchange in the front, and the heat exchange is increased toward the rear to form a heat exchanger such as countercurrent. Through experiments, this structure design can achieve better heat exchange effect and descaling effect.

[0170]Preferably, the flow direction of the fluid in the fluid passage, the same side (left or right side) the heat-insulating tube set is provided, from the upward direction, the same side (left or right) adjacent The spacing of the heat transfer tube is constantly smaller.

[0171]Preferably, the spacing between the fluid in the fluid in the fluid channel is constantly increasing. The specific effect is similar to the effect of the previous pipe diameter.

[0172]In the test, the volume, distance, and the volume of the upper right upper tube 22, and the volume of the collector tank can have an effect on heat exchange efficiency and uniformity. If the volume of the collector is too small, the steam is overheating, the heat cannot be transferred to the exothermic tube and the upper left tube, which is too high, causing the steam condensation, and cannot be transmitted, the left upper tube 21, the upper right upper tube 22 The volume must be applied with the collecting tank volume, otherwise the steam condensation is too fast or too slow, which will cause deterioration of heat transfer, and the distance between the left upper tube 21, the upper right upper tube 22 can also cause too poor heat transfer efficiency, distance too Small, the release tube distribution is too dense, and the heat transfer efficiency, the distance between the left upper tube 21, and the right upper tube 22 also needs to be applied with the distance between the collector box, otherwise the distance between them affects the accommodation. The volume of liquid or vapor, affects the vibration of the free end, thereby affecting heat transfer. Therefore, the volume, distance, and the volume of the upper right upper tube 22 have a certain relationship of the volume, distance, and the volume of the collector tank.
