Description

TECHNICAL FIELD

[0001] The utility model relates to a circulating technical field, concretely a novel circulating structure based on solar vacuum tube. BACKGROUND

[0002] The glass vacuum tube is adopted by most types of solar water heaters at present because of simple manufacturing process and low cost. In order to improve the heat efficiency of the vacuum tube, the main methods adopted at present are: 1, improving the heat absorption layer to improve the vacuum degree; 2, increasing the diameter of the vacuum tube; and 3, adding a vacuum glass tube or metal wing piece in the vacuum tube. However, the first improvement is limited, and it is difficult to improve the absorption rate more than 95%. The second improvement improves the heat efficiency, but the cost is also greatly increased, and some have exceeded the medium heat pipe type vacuum tube. Moreover, the more the diameter of the vacuum tube is, the more the hot water retained in the vacuum tube is, which increases the weight of the water heater itself and the installation difficulty, especially for the split type water heater. The cost of the third improvement is still too high. SUMMARY

[0003] The technical problem to be solved by the utility model is to overcome the above technical defects.

[0004] In order to solve the above problems, the technical scheme of the utility model is as follows: a novel circulating structure based on solar vacuum tube, comprising a heat preservation continuous box, a solar vacuum tube and a water tank.

[0005] A circulating conduit is inserted on the water tank, the circulating conduit is placed in the heat preservation continuous box, the solar vacuum tube is located on both sides of the heat preservation continuous box and is uniformly distributed, the solar vacuum tube is connected with the circulating conduit, the circulating conduit is connected with the water tank, a sealing cover is arranged between the circulating conduits, and a water pump is arranged on the circulating conduit.

[0006] Further, an electromagnetic valve is connected to the upper end of the circulating conduit.

[0007] Further, the circulating conduits are staggered and inserted with the solar vacuum tube, the long end of the circulating conduit is located on the lower side, and the end is located on the upper side.

[0008] Compared with the prior art, the utility model has the advantages of:

[0009] The heat preservation continuous box is arranged on the utility model, the circulating conduit is inserted in the heat preservation continuous box, the circulating conduit is connected with the solar vacuum tube, so that the siphon effect of the liquid can be utilized, the power required for circulation is reduced, the practicability is improved, and the heat conversion rate can be improved by adding the pump circulation in the equipment.
