Specific implementation

Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] As Figures 1-6 Indicated in the drawing, a low-temperature economizer heat pipe fastening assembly, including first frame 1, first frame 1 is connected with a plurality of first wave-shaped clamping plate 5, first wave-shaped clamping plate 5 is welded with second wave-shaped clamping plate 3, and a plurality of heat pipe mounting hole 7 is formed between first wave-shaped clamping plate 5 and second wave-shaped clamping plate 3.

[0023] The heat pipe 2 is inserted into the heat pipe mounting hole 7, and the both ends of the first wave-shaped clamping plate 5 are provided with welding edges 54.

[0024] The first wave-shaped clamping plate 5 and the second wave-shaped clamping plate 3 are arranged on one side of the first frame 1.

[0025] The first wave-shaped clamping plate 5 is provided with a first wave-shaped edge 52 and a second wave-shaped edge 53, and the first wave-shaped clamping plate 5 is provided with a first ash leakage hole 51.

[0026] The second wave-shaped clamping plate 3 is provided with a third wave-shaped edge 32 and a fourth wave-shaped edge 33, and the second wave-shaped clamping plate 3 is provided with a second ash leakage hole 31.

[0027] The heat pipe 2 is welded with a sealing plate 6, and the sealing plate 6 is welded with a connecting plate 4.

[0028] Specifically, the first frame 1 is provided with a plurality of clamping and fixing positions along the axial direction of the heat pipe 2 to clamp and fix the heat pipe 2 from different positions; the heat pipes 2 are arranged in a square shape along the longitudinal and transverse directions.

[0029] Working principle: The low-temperature economizer is an energy-saving device in the boiler. The low-temperature economizer product is used for the coal-fired boiler of the power plant and is an energy-saving device in the thermal energy industry. There are two energy-saving devices at the tail of the boiler. One is a water preheater entering the boiler, which uses the waste heat in the boiler flue to heat the water entering the boiler, thereby saving coal. This is called an economizer in the industry. The economizer of the present application absorbs heat in the flue at the lower part of the heat pipe 2. The heat is transferred to the upper part of the heat pipe 2 by the heat pipe 2. The upper part has a water jacket pipe, which transmits heat to the water in the water jacket pipe.

[0030] The heat pipe 2, as the core component, is filled with a specific working fluid. When one end of the heat pipe 2 is heated, the working fluid evaporates and carries heat upwards along the heat pipe 2 to the condensing section, where the heat is released to an external medium such as air or water, causing the vapor to condense into a liquid and returning to the evaporation section by gravity or capillary action. This cycle continues, achieving efficient heat transfer.

[0031] The first and second wave-shaped clamping plates 5 and 3 are provided with first and second ash discharge holes 51 and 31, which provide a discharge path for the ash. In actual operation, due to the action of airflow or the vibration of the equipment itself, the ash attached to the surface of the heat pipe 2 will gradually fall off and be naturally discharged through these ash discharge holes, avoiding the influence of ash accumulation on heat exchange efficiency and reducing the need for cleaning and maintenance.

[0032] The plurality of heat pipe mounting holes 7 formed between the first and second wave-shaped clamping plates 5 and 3 are used to accurately position and fix the heat pipe 2. The design of the welding edge 54 enhances the connection strength between the heat pipe 2 and the frame, ensuring that the heat pipe 2 does not shift or loosen when subjected to external impact or vibration, maintaining good heat transfer contact conditions.

[0033] The end of the heat pipe 2 is welded with a sealing plate 6, and the sealing plate 6 is further welded with a connecting plate 4. This design not only plays a sealing role to prevent leakage of the working fluid, but also provides an interface for convenient connection with other pipelines or equipment, facilitating system integration and future expansion and upgrading.

[0034] The above description of the embodiments is only used to help understand the method of the present application and its core idea. It should be noted that for ordinary skilled persons in the art, without departing from the principles of the present application, the present application can be improved and modified in many ways, and these improvements and modifications also fall within the protection scope of the claims of the present application.
