Description

A uniform heat exchange energy-saving heat exchanger Technical Field

[0001] This utility model relates to the field of heat exchange technology, and in particular to a uniform heat exchange energy-saving heat exchanger. Background Technology

[0002] A heat exchanger is an energy-saving device that facilitates heat transfer between two or more fluids at different temperatures. It is widely used in numerous industrial fields such as chemical, petroleum, power, food, pharmaceutical, metallurgy, energy, and environmental protection, and is one of the key devices for improving energy utilization, optimizing process flows, and achieving energy conservation and emission reduction. The most commonly used heat exchanger is the tubular heat exchanger, which consists of a shell, heat exchange tubes, and baffles. The heat exchange tubes contain a working medium, and heat transfer occurs through phase change.

[0003] Existing tubular heat exchangers utilize baffles to increase the fluid's travel distance, thereby improving heat exchange efficiency. However, increasing the fluid travel distance with baffles can lead to poor localized flow, affecting heat exchange uniformity and resulting in heat loss. Furthermore, existing tubular heat exchangers are mounted on a fixed frame on the outer shell, but the relative height of the frame is not adjustable, preventing adjustments based on actual installation conditions and resulting in poor installation flexibility. Summary of the Invention

[0004] The main objective of this invention is to provide a uniform heat exchange energy-saving heat exchanger that can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0011] Preferably, the heat exchange structure includes a conveying pipe, a spiral baffle, and a spiral heat exchange tube. The conveying pipe is fixedly connected to the spiral baffle, and the conveying pipe and the spiral baffle are fixedly installed inside the shell. The spiral heat exchange tube is wound around the conveying pipe and passes through the spiral baffle. The two ends of the spiral heat exchange tube pass through the first isolation plate and the second isolation plate, respectively. The spiral direction of the spiral heat exchange tube is opposite to that of the spiral baffle.

[0012] Preferably, the mounting structure includes a fixed seat, a sliding groove, a fixed plate, a mounting base plate, an oblong hole, and a connecting block. The sliding groove is formed on the fixed seat, and the fixed seat is fixed to the outer wall of the housing. The fixed plate is disposed on the fixed seat. The oblong hole is formed on the mounting base plate, and the mounting base plate is fixedly connected to the connecting block. The connecting block is slidably connected in the sliding groove.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As shown in Figures 1-4, a uniform heat exchange energy-saving heat exchanger includes a shell 1. A first end 2 and a second end 3 are fixed to both ends of the shell 1. A first isolation plate 4 and a second isolation plate 5 are respectively installed at both ends inside the shell 1. A heat exchange structure 6 is installed inside the shell 1, and an installation structure 7 is provided on the outer surface of the shell 1. A heat medium discharge pipe 10 is fixed to one end of the shell 1, and a heat medium inlet pipe 11 is installed at the other end of the shell 1. Connecting flanges are provided on the shell 1, the first end 2, and the second end 3, and the first end 2 and the second end 3 are fixedly connected to the shell 1 through the connecting flanges. A refrigerant inlet pipe 8 is fixed to the first end 2, and a refrigerant discharge pipe 9 is fixed to the second end 3. The two ends of the heat exchange structure 6 are respectively connected to the first isolation plate 4 and the second isolation plate 5, and the installation structures 7 are symmetrically distributed on the shell 1.

[0022] When installing the energy-saving heat exchanger, the shell 1 is stably set by the installation structure 7. The heat exchange structure 6 is provided inside the shell 1. The first end 2 and the second end 3 are fixed to the two ends of the shell 1 by connecting flanges and screws. After connecting the pipes, the heat exchange work begins.

[0023] During the heat exchange process, cold water, acting as the refrigerant, enters the first end 2 through the refrigerant inlet pipe 8. Blocked by the first isolation plate 4, the cold water flows through the heat exchange section of the heat exchange structure 6. Simultaneously, hot water, acting as the heat medium, enters the shell 1 through the heat medium inlet pipe 11 and flows through the baffle section of the heat exchange structure 6. The hot and cold water exchange heat through the heat exchange structure 6. The cold water, having absorbed heat, is heated and discharged from the refrigerant outlet pipe 9 on the second end 3, while the hot water, after heat exchange, cools down and is eventually discharged from the heat medium outlet pipe 10. This completes the heat exchange process. Due to the design of the heat exchange structure 6, uniform heat exchange is achieved during the heat exchange process.

[0024] According to the above implementation scheme, the heat exchange structure 6 includes a conveying pipe 601, a spiral baffle 602, and a spiral heat exchange tube 603. The conveying pipe 601 is fixedly connected to the spiral baffle 602, and the conveying pipe 601 and the spiral baffle 602 are fixedly installed inside the shell 1. The spiral heat exchange tube 603 is wound around the conveying pipe 601 and passes through the spiral baffle 602. The two ends of the spiral heat exchange tube 603 pass through the first isolation plate 4 and the second isolation plate 5, respectively. The spiral direction of the spiral heat exchange tube 603 is opposite to that of the spiral baffle 602. By setting the heat exchange structure 6, the conveying pipe 601 and the spiral baffle 602 are arranged between the two isolation plates, which can increase the fluid travel and prevent local poor flow. When used in conjunction with the spiral heat exchange tube 603, which spirals in the opposite direction to the spiral baffle 602, the heat exchange efficiency is improved, energy saving effect is achieved, and heat exchange uniformity is increased.

[0025] During the heat exchange process, the hot water, which serves as the heat transfer medium, enters the shell 1. Part of it flows inside the delivery pipe 601, while the other part flows spirally along the spiral baffle 602. At the same time, the cold water, which serves as the refrigerant, enters the spiral heat exchange tube 603. The spiral heat exchange tube 603 is wound around the delivery pipe 601 and passes through the spiral baffle 602, thereby realizing the heat exchange between the hot water and the cold water. After the heat exchange, the cold water is heated and discharged, while the hot water is cooled and discharged.

[0026] According to the above implementation scheme, the installation structure 7 includes a fixed seat 701, a sliding groove 702, a fixed plate 703, a mounting base plate 704, an oblong hole 705, and a connecting block 706. The sliding groove 702 is formed on the fixed seat 701, and the fixed seat 701 is fixed to the outer wall of the housing 1. The fixed plate 703 is set on the fixed seat 701. The oblong hole 705 is formed on the mounting base plate 704, and the mounting base plate 704 is fixedly connected to the connecting block 706. The connecting block 706 is slidably connected in the sliding groove 702. The mounting structure 7 also includes a lifting rod 707, an adjusting screw 708, a limiting block 709, and a hexagonal groove 710. The lifting rod 707 is fixed on the mounting base plate 704. The lower end of the adjusting screw 708 is threaded to the lifting rod 707, and the upper end of the adjusting screw 708 passes through the fixing plate 703. The limiting block 709 is located at the upper end of the adjusting screw 708, and the hexagonal groove 710 is formed at the top of the adjusting screw 708.

[0027] The entire heat exchanger is installed using the installation structure 7. The height of the lifting rod 707 and the mounting base 704 can be adjusted using the adjusting screw 708. This ensures the stability of the heat exchanger installation on uneven ground. Each fixed seat 701 is equipped with two mounting bases 704, and these two mounting bases 704 are independently set by the lifting rod 707 and other structures, allowing for individual adjustment and further increasing the flexibility and adaptability of the installation.

[0028] When installing the heat exchanger, the height of the corresponding mounting base 704 is adjusted according to the actual situation. During adjustment, the adjusting screw 708 is rotated through the tool connecting the hexagonal groove 710. Under the action of the limit block 709, the adjusting screw 708 rotates on the fixed plate 703 without changing its height, thereby driving the lifting rod 707 to rise and fall. Driven by the lifting rod 707, the mounting base 704 moves along the sliding groove 702 on the fixed seat 701 through the connecting block 706, thereby changing the height of the mounting base 704. After the adjustment is completed, the bolt passes through the oblong hole 705 to fix the mounting base 704, thus completing the installation and fixation of the entire heat exchanger. The structure is simple and the operation is convenient and quick.

[0029] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
