Description
TECHNICAL FIELD
[0001] The utility model relates to heat recovery equipment technical field, concretely relates to a heat exchange structure. BACKGROUND
[0002] Waste heat refers to sensible heat and latent heat that is not reasonably utilized in the original design of the energy consumption device of the industrial enterprise that has been put into operation due to the limitations of history, technology, concept and other factors, which includes high-temperature waste gas waste heat, cooling medium waste heat, waste steam and waste water waste heat, high-temperature product and slag waste heat, chemical reaction waste heat, flammable waste gas, waste liquid and waste material waste heat, etc.
[0003] With the improvement of people's living standards, hot water is more and more widely used, such as: household kitchen vegetable washing water, bathroom hand and foot washing, shower, washing machine, bathtub, commercial swimming pool, bathhouse, water meeting, etc. In actual use, in order to meet the use requirements, a large amount of energy is needed to heat the water to the required temperature, but the actual effective heat energy utilization is less, for example, in the process of taking a bath, taking Guizhou area as an example, the temperature of tap water is 2-5℃ in winter and 15-19℃ in summer, while the temperature of bathing water is between 40-44℃, and the actual heat utilization rate of shower water is only 20%, more heat energy is discharged with domestic wastewater, which wastes a lot of energy and increases the greenhouse effect.
[0004] REFERENCE Figure 1 The applicant provides a heat exchange structure, which comprises a heat exchange tank, a fixed support is fixedly arranged on the heat exchange tank, and the heat exchange pipes are fixedly connected to the fixed support and are distributed in a serpentine shape. The heat exchange pipes are connected to tap water or cold water to be heated, and the waste hot water is introduced into the heat exchange tank. When the waste hot water passes through the heat exchange pipes, the temperature of the tap water or cold water increases after absorbing the heat of the waste hot water. However, this heat exchange mechanism has the following problems: firstly, the heat exchange pipes cannot be disassembled and taken out of the heat exchange tank, secondly, the part of the heat exchange pipes between the fixed supports is prone to corrosion and deformation under high temperature conditions, and the heat exchange is poor due to dirt covering, and the spacing between adjacent parts of the heat exchange pipes is not limited, and the internal space of the heat exchange tank is limited, so that the heat exchange pipes with longer length cannot be installed, thereby the heat exchange area and the heat exchange effect cannot be improved. UTILITY MODEL CONTENTS
[0005] The utility model intends to provide a heat exchange structure, which can facilitate the disassembly of the heat exchange pipes and limit the spacing between adjacent parts of the heat exchange pipes.
[0006] In order to solve the above problems, the utility model provides the following technical scheme:
[0007] The heat exchange structure comprises a connecting beam, heat exchange pipes and symmetrically arranged U-shaped beams, the connecting beam is fixedly connected between the two U-shaped beams, the U-shaped beams are uniformly spaced with a plurality of through holes along the axis of the U-shaped beams, and each U-shaped beam is fixedly connected with a fixing ring between adjacent through holes, and the heat exchange pipes are sequentially arranged through the plurality of fixing rings on the two U-shaped beams and are distributed in a serpentine shape.
[0008] The working principle and beneficial effects of the heat exchange structure are as follows:
[0009] The heat exchange pipes are sequentially arranged through the plurality of fixing rings on the two U-shaped beams, the through holes are used for operation and use when the heat exchange pipes are arranged, the heat exchange pipes and the U-shaped beams are fixed together through the fixing rings to form an integral whole, the heat exchange pipes are not deformed, a fixed shape is formed, batch production is realized, and the heat exchange pipes are convenient to replace in the later period. The heat exchange pipes are distributed in a serpentine shape with a smaller spacing, the overall geometric size is more compact, the heat exchanger is suitable for more narrow spaces, and the heat exchanger is more widely applied; the heat exchange pipes with a longer length can be arranged in the same installation space, the contact area with waste hot water is increased, the heat exchange efficiency is higher, and the heat exchanger is more energy-saving. The two U-shaped beam supports are fixed with the connecting beam, the connecting beam and the two fixing beams are connected as an integral whole, the connecting beam has the effect of assisting in fixing the heat exchange pipes, and the connecting beam can also act as a handle in the assembly and disassembly process, so that the heat exchange pipes are convenient to take and place.
[0010] Optimally, the connecting beam is a cross-shaped beam. The cross-shaped beam has a better fixing effect on the two U-shaped beams.
[0011] Optimally, the connecting beams are symmetrically arranged, and the two connecting beams are located at the two ends of the U-shaped beams. The two ends of the U-shaped beams are fixed through the connecting beams, and the heat exchange pipes are better protected from deformation.
[0012] Optimally, the axis of the fixing ring is perpendicular to the axis of the connecting beam. This optimization scheme is beneficial to the installation of the heat exchange pipes through the plurality of fixing rings.
[0013] Optimally, the heat exchange pipe is sleeved with a flange plate, and the heat exchange pipe is also sleeved with a movable nut. The flange plate is connected with the external thread corresponding to the heat exchange equipment, and there is a sealing gasket in the middle. The movable nut is screwed with the external thread to extrude the sealing ring, so as to achieve sealing connection. The assembly and disassembly are convenient, and the heat exchange is kept high for a long time.
[0014] Optimally, the shape of the fixing ring is oval. BRIEF DESCRIPTION OF DRAWINGS

[0016] Figure 2 It is an internal structure schematic view of a heat exchange structure in the utility model;
[0017] Figure 3A schematic diagram of the connection of the heat exchange tubes fixed by the middle fixed ring. Detailed Implementation
[0018] The following detailed description illustrates the specific implementation method:
[0019] The reference numerals in the accompanying drawings include: heat exchange tube 1, connecting beam 2, U-shaped beam 3, fixing ring 4, and through hole 5.
[0020] In the following statements, directional terms such as "left," "right," "up," and "down" are based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the direction while maintaining their relative positions, it will not affect the implementation of the plan.
[0021] Example: A heat exchange structure, such as Figure 2 As shown, it includes two connecting beams 2, heat exchange tubes 1, and symmetrically arranged U-shaped beams 3. The connecting beams 2 are fixedly connected between the U-shaped beams 3 on both sides; as Figure 3 As shown, each U-shaped beam 3 has 17 through slots 5 evenly spaced along its axis. Each U-shaped beam 3 is fixedly connected to a fixed ring 4 between adjacent through slots 5. There are 16 fixed rings 4 in total. The heat exchange tube 1 passes through multiple fixed rings 4 on both sides of the U-shaped beam 3 in sequence and is distributed in a serpentine pattern.
[0022] This design involves bending the heat exchange tube 1 and threading it sequentially through 32 fixing rings 4 on both sides of the U-shaped beams 3. The through grooves 5 are used for threading the heat exchange tube 1 and provide installation space for the fixing rings 4. The 32 fixing rings 4 secure the heat exchange tube 1 to the U-shaped beams 3 together, forming a unified whole. This prevents the heat exchange tube 1 from deforming, maintaining a fixed shape, allowing for mass production and easy replacement later. Furthermore, the serpentine distribution of the heat exchange tubes 1 results in a smaller spacing and a more compact overall geometry, making the heat exchanger adaptable to more confined spaces and wider in application. Longer heat exchange tubes 1 can be installed within the same installation space, increasing the contact area with wastewater, resulting in higher heat exchange efficiency and greater energy savings. Connecting beams 2 are fixed to the two U-shaped beams 3 supports. The connecting beams 2 and the two fixing beams are connected as a whole. The connecting beams 2 assist in fixing the heat exchange tube 1 and also act as handles during assembly and disassembly for easy placement and removal.
[0023] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
