Description

Technical Field

[0001] This utility model relates to the field of rapid heat dissipation through dual-exchange pipelines, specifically a combined high-efficiency dual 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 transfers heat from a higher-temperature fluid to a lower-temperature fluid, bringing the fluid temperature to the specified parameters to meet process requirements. It is also a key component in improving energy efficiency. Our company's water treatment processes have specific temperature requirements. For example, in northern winters, excessively low water temperatures can reduce the water flux of membrane bioreactors (MBR), ultrafiltration membranes, or reverse osmosis membrane systems. Plate heat exchangers can raise the inlet water temperature to a suitable range, ensuring the normal operation of the membrane system and improving effluent quality and treatment efficiency. Simultaneously, their smooth heat exchange surface helps reduce fouling, maintains water quality stability, and meets the needs of treatment processes with high water quality requirements. Previously used radiators were often insufficient for the on-site requirements, frequently causing damage to equipment and other devices due to inadequate heat dissipation.

[0003] To address these issues, a combined high-efficiency dual heat exchanger is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a combined high-efficiency dual heat exchanger to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined high-efficiency dual heat exchanger, comprising heat dissipation tubes, exchange tubes, and heat dissipation fins.

[0006] The heat dissipation pipe has an inner cavity for containing heat-absorbing liquid, and the exchange pipe has an inner cavity for containing the heat dissipation pipe and the liquid to be cooled. The heat dissipation pipe extends into the interior of the exchange pipe so that the heat-absorbing liquid in the heat dissipation pipe can absorb the heat of the liquid inside the exchange pipe.

[0007] The heat sink assembly forms an inner cavity to accommodate the exchange tube, which extends into the inner cavity of the heat sink assembly. The heat sink assembly is used for secondary cooling of the liquid inside the exchange tube.

[0008] Furthermore, both the heat dissipation pipe and the heat exchange pipe adopt a rectangular structure.

[0009] Furthermore, the two ends of the heat dissipation pipe and the exchange pipe are flush, and the two ends of the heat dissipation pipe and the exchange pipe share an integral baffle plate, which is used to prevent liquid leakage inside the heat dissipation pipe and the exchange pipe.

[0010] Furthermore, a first connecting pipe is installed at both ends of the exchange tube, and the first connecting pipe is used to transport the liquid inside the exchange tube.

[0011] Furthermore, a second connecting pipe is installed on the integral baffle plate, the second connecting pipe being connected to the heat dissipation pipe and used to transport the heat-absorbing liquid.

[0012] Furthermore, the heat sink assembly includes a single heat sink, which is mounted on the outside of the heat exchange tube.

[0013] Furthermore, the combined high-efficiency dual heat exchanger also includes heat dissipation tubes and fins, which are installed on the outside of the heat dissipation tubes and extend into the inner cavity of the heat exchange tubes together with the heat dissipation tubes.

[0014] Analysis shows that this utility model provides a combined high-efficiency dual heat exchanger, including a heat dissipation tube, an exchange tube, and a heat dissipation fin assembly. The heat dissipation tube has an internal cavity for containing a heat-absorbing liquid, and the exchange tube has an internal cavity for containing the exchange tube and the liquid to be cooled. The heat dissipation tube extends into the exchange tube so that the heat-absorbing liquid inside the heat dissipation tube can absorb heat from the liquid inside the exchange tube. The heat dissipation fin assembly has an internal cavity for containing the exchange tube, and the exchange tube extends into the internal cavity of the heat dissipation fin assembly. The heat dissipation fin assembly is used for secondary cooling of the liquid inside the exchange tube. The heat-absorbing liquid inside the heat dissipation tube carries away most of the heat from the liquid inside the exchange tube, causing the liquid inside the exchange tube to cool down rapidly. The heat dissipation fin assembly further enhances the cooling efficiency. This device brings significant energy-saving benefits through the dual-pipe structure of the exchange tube and heat dissipation tube, significantly improves heat dissipation efficiency through enhanced heat transfer via dual flow channels, and further improves heat dissipation efficiency through the heat dissipation fin assembly outside the exchange tube.

[0015] Compared with the closest existing technology, the technical solution provided by this utility model has the following advantages: Addressing the technical problem that current radiators often fail to meet on-site usage requirements, frequently causing damage to equipment and devices due to inadequate heat dissipation, this invention offers higher stability and reliability compared to single-plate or shell-and-tube heat exchangers. Its combined dual-structure design provides greater adaptability to pressure and temperature variations, improving the device's resistance to shocks and fluctuations, and enabling it to better handle complex operating conditions over long periods. The improved heat exchange efficiency of this invention relies on the dual-channel structure design between the exchange tubes and the heat dissipation tubes. Compared to single-plate or shell-and-tube heat exchangers, it allows for the reuse or recycling of the heat-absorbing liquid within the heat dissipation tubes, resulting in significant energy-saving benefits while accommodating a wider range of operating conditions.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] It should be noted that in the description of this utility model, the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0023] This utility model provides a technical solution: a combined high-efficiency dual heat exchanger, including a heat dissipation tube 1, an exchange tube 2, and a heat dissipation fin assembly 3.

[0024] The heat dissipation pipe 1 has an inner cavity for containing heat-absorbing liquid, and the heat exchange pipe 2 has an inner cavity for containing heat dissipation pipe 1 and liquid to be dissipated. The heat dissipation pipe 1 extends into the interior of the heat exchange pipe 2 so that the heat-absorbing liquid in the heat dissipation pipe 1 can absorb the heat of the liquid inside the heat exchange pipe 2.

[0025] The heat sink assembly 3 forms an inner cavity to accommodate the exchange tube 2. The exchange tube 2 extends into the inner cavity of the heat sink assembly 3, and the heat sink assembly 3 is used for secondary cooling of the liquid inside the exchange tube 2.

[0026] By combining heat dissipation pipe 1 and heat exchange pipe 2, the heat absorption effect of the heat absorber is enhanced. Furthermore, the combined dual structure is better able to cope with complex operating conditions during long-term operation and reduces the risk of failure: it is more resistant to scaling and easy to clean, has stronger pressure and temperature adaptability, and is more resistant to shock and fluctuations.

[0027] In this embodiment, as Figure 1 As shown, the heat dissipation pipe 1 and the exchange pipe 2 are two sets. When the heat dissipation pipe 1 is filled with heat-absorbing liquid, it can carry away most of the heat of the liquid in the exchange pipe 2. This makes it easier for the liquid that needs to be cooled to cool down quickly. At the same time, the two exchange pipes 2 share a heat dissipation fin group 3 on the outside, realizing secondary cooling of the liquid in the exchange pipe 2. This improves the heat dissipation efficiency of the device, saves materials, and reduces costs.

[0028] In this embodiment, both the heat pipe 1 and the exchange pipe 2 adopt a rectangular structure.

[0029] When the heat exchange tube 1 is filled with heat-absorbing liquid, most of the heat is carried away by the flow energy, which facilitates the rapid cooling of the liquid that needs to be cooled. The heat exchange tube 2 also adopts a square structure, which makes it convenient to cooperate with the heat exchange tube 1 for rapid heat dissipation during use. Through the optimization of the plate heat exchange structure, problems such as scaling, corrosion, and aging of rubber strips can be effectively reduced. The flat heat exchange surface helps to reduce the adhesion of dirt, maintain water quality stability, and meet the treatment process with high water quality requirements.

[0030] Preferably, the two ends of the heat dissipation pipe 1 and the exchange pipe 2 are flush, and the two ends of the heat dissipation pipe 1 and the exchange pipe 2 share an integral baffle plate 4. The integral baffle plate 4 is used to prevent liquid leakage in the heat dissipation pipe 1 and the exchange pipe 2. The use of integral baffle plate 4 facilitates on-site processing and maintenance and saves materials.

[0031] Preferably, both ends of the exchange pipe 2 are equipped with first connecting pipes 5. The first connecting pipes 5 are used to transport the liquid in the exchange pipe. The condensate can be recovered through the first connecting pipes 6 to reduce energy consumption costs. The condensate can be recovered for use in preheating water intake or other process steps.

[0032] The integral baffle plate 4 is equipped with a second connecting pipe 6, which is connected to the heat dissipation pipe 1 and is used to transport heat-absorbing liquid.

[0033] In this embodiment, as Figure 2The output ends of the first connecting pipe 5 and the second connecting pipe 6 are both equipped with connecting flanges, which facilitates the combination with other heat exchangers for heat dissipation according to the site conditions each time it is used.

[0034] In practical engineering applications, its "modular" structure brings stronger adaptability to different scenarios, while also having significant energy-saving benefits: modular combination, wide adaptability, high waste heat recovery efficiency, significant energy saving, small size, low footprint and low installation cost.

[0035] Preferably, the heat sink assembly 4 includes a single-piece heat sink, which is installed on the outside of the heat exchange tube 2. The advantage of the single-piece heat sink is that it has good thermal conductivity, can be mass-produced, and can save materials and reduce costs.

[0036] More preferably, the combined high-efficiency dual heat exchanger also includes heat dissipation tubes and fins, which are installed on the outside of the heat dissipation tube 1 and extend into the inner cavity of the exchange tube 2 together with the heat dissipation tube 1; the heat dissipation tubes and fins further improve the heat transfer of the heat-absorbing liquid in the heat dissipation tube 1, increase the contact area between the heat dissipation tube 1 and the exchange tube 2, and thus improve the heat exchange efficiency of the device.

[0037] The specific process of absorbing heat from a liquid using this device is as follows: According to the on-site working conditions, the other parts of this device are connected by bolting the flange connecting discs on the first connecting pipe 5 and the second connecting pipe 6. The heat-absorbing liquid is introduced through the second connecting pipe 6, and the liquid to be cooled is introduced through the first pipe 5. The heat of the liquid in the heat exchange pipe 2 is carried away by the flow of the heat-absorbing liquid in the heat dissipation pipe 1, as well as the heat dissipation on the outside of the heat exchange pipe 2 by the heat dissipation fin group 4. The inner and outer sides of the liquid in the heat exchange pipe 2 can be cooled. After the work is completed, the condensate is recovered through the first connecting pipe 5 and used for preheating the inlet water or other process steps.

[0038] In summary, this utility model achieves the following technical effects: 1) This utility model enhances heat transfer through the dual-pipe structure design of heat dissipation pipe 1 and exchange pipe 2, copes with complex working conditions, reduces the risk of failure, and improves the anti-fouling and easy-to-clean properties of the device by adopting a rectangular structure for heat dissipation pipe 1 and exchange pipe 2 and using a plate heat exchange structure. It also has stronger pressure and temperature adaptability and can improve the ability to resist impact and fluctuation.

[0039] 2) This utility model achieves rapid cooling of the liquid in the exchange tube 2 by setting a heat sink group 4 on the outside of the exchange tube 2 and cooperating with the heat absorption liquid in the heat sink 1.

[0040] 3) Other heat exchangers can be combined with this heat exchanger through the first connecting pipe 5 and the second connecting pipe 6. Specifically, they can be connected to the connecting flange of another combined high-efficiency dual heat exchanger by connecting flange and then quickly connected by bolts. The modular structure brings stronger adaptability to different scenarios and has significant energy-saving benefits: modular combination, wide adaptability, high waste heat recovery efficiency, significant energy saving, small size, low footprint and low installation cost.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
