Description

Technical Field

[0001] The utility model relates to the field of heat dissipation equipment, in particular to a novel fin tube structure. Background Art

[0002] Heat exchange coils are common heat exchange equipment in the prior art, but the forms of heat exchange coils in the prior art are similar, generally in the form of a long metal tube repeatedly bent. This form of coil has been well applied in many fields, but in the field of heat recovery, the soft water in the coil needs to form steam to rise under the action of heat exchange, and the coil form in the prior art has many disadvantages, including slow circulation, large circulation resistance caused by too many elbows, and thus low heat exchange efficiency. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a new type of fin tube structure with multiple coils connected in parallel to achieve better uniformity of heat exchange effect and higher heat exchange efficiency, that is, higher steam conversion rate.

[0004] The equipment comprises a water inlet main pipe, and the water inlet main pipe is connected to a plurality of water inlet branch pipes;

[0005] The water inlet branch pipe is connected to a plurality of heat exchange coils, one end of the heat exchange coil is connected to the water inlet branch pipe, and the other end is connected to the return branch pipe, and the return branch pipe is connected to the return main pipe;

[0006] The end of the heat exchange coil connected to the water inlet branch pipe is lower than the end connected to the water return branch pipe, that is, the heat exchange coil is in an inclined form.

[0007] The effect achieved by this is that the water in the water main pipe flows to multiple water inlet branches, and then flows to the heat exchange coils from the multiple water inlet branches. The water in the heat exchange coils evaporates to form steam through heat exchange, and enters the steam pipe from the upper part of the return branch pipe. The water in the heat exchange coils flows into the return water main pipe through the return branch pipe. In other words, in the heat exchange steam generating equipment, the water in multiple heat exchange coils does not interfere with each other, and heat exchange and steam are produced synchronously, thereby achieving higher heat exchange efficiency and higher steam conversion rate.

[0008] The beneficial effects of the utility model are as follows: the utility model solves the problems of low heat exchange efficiency, slow circulation and large circulation resistance of the coil in the prior art, realizes high-efficiency steam conversion, smaller pipe resistance makes water circulation more convenient and the maintenance cycle is longer. At the same time, the equipment structure is simple and has greater market promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The end of the heat exchange coil 5 connected to the water inlet branch pipe 3 is lower than the end connected to the water return branch pipe 7. That is, the heat exchange coil 5 is in an inclined form.

[0016] The effect achieved by this is that the water in the water inlet main pipe 2 flows to the multiple water inlet branch pipes 3, and then flows to the heat exchange coil 5 from the multiple water inlet branch pipes 3. The water in the heat exchange coil 5 evaporates through heat exchange to form steam, and enters the steam pipe from the upper part of the return branch pipe 7. The water in the heat exchange coil 5 flows into the return main pipe 6 through the return branch pipe 7. In other words, in the heat exchange steam generating device, the water in the multiple heat exchange coils 5 does not interfere with each other, and heat exchange and steam are produced synchronously, thereby achieving the effect of higher heat exchange efficiency and higher steam conversion rate.

[0017] Furthermore, the water inlet valve 1 of the water inlet main pipe 2 is located at the lower part of the water inlet main pipe 2 .

[0018] Furthermore, the water inlet branch pipes 3 are connected to the water inlet main pipe 2 in a uniform array from bottom to top, and the arrangement direction thereof is perpendicular to the water inlet main pipe 2, and the plurality of water inlet branch pipes 3 are arranged in parallel.

[0019] The effect achieved in this way is to ensure that the water flows in smoothly and evenly.

[0020] Furthermore, the heat exchange coil 5 is also provided with heat exchange fins 4 .

[0021] The effect achieved by this is to improve the heat exchange effect.

[0022] Furthermore, the water return branch pipes 7 are arranged in a uniform array from top to bottom, and a water return main pipe 6 is arranged at both ends of the water return branch pipes 7. That is to say, there are two water return main pipes 6 in total.

For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
