Description

Technical Field

[0001] This utility model relates to cooling equipment, and more particularly to a high-efficiency cooler. Background Technology

[0002] Traditional cooling equipment faces significant technical bottlenecks: First, single-stage cooling structures are prone to low heat exchange efficiency. For example, water tank cooling systems are prone to scaling and blockage due to their single flow path, and small evaporators in refrigeration equipment often lead to freezing and blockage risks. Large cooling towers, relying on packing for heat exchange, suffer from high energy consumption and large temperature differences. Second, structural complexity and soaring operation and maintenance costs are significant. For instance, crossflow closed-circuit cooling towers are limited by the difficulty of non-standard design, and industrial air coolers are difficult to install and maintain due to their multi-channel cavities and complex connections. Frequent chemical cleaning also exacerbates water waste. Third, insufficient temperature control precision is a problem. Refrigeration systems are prone to ice blockage because the evaporation temperature is close to the freezing point of cold water, while dry cooling towers are limited by the dry-bulb temperature of the air, causing a sharp drop in cooling efficiency and making it difficult to achieve uniform heat dissipation.

[0003] Although existing technologies attempt to optimize by adding heat exchangers or vibration descaling mechanisms, they are difficult to balance the requirements of efficient heat exchange and low maintenance costs due to defects such as low integration, high energy consumption, and reliance on imported compressors.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a high-efficiency cooler that has greater industrial value. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a high-efficiency cooler.

[0006] This utility model discloses a high-efficiency cooler, comprising two identical cooling sections installed at different heights. The discharge pipe of the upper cooling section is connected to the inlet pipe of the lower cooling section via a pipeline. A through cooling chamber runs through the middle of the two cooling sections. The upper and lower ends of the cooling chamber are respectively connected to a cooling medium inlet and a cooling medium outlet. A complete circle of pipes is arranged on the side walls of both cooling sections, with one end of the pipe connected to the inlet pipe and the other end connected to the discharge pipe.

[0007] This high-efficiency cooler adopts a dual-cooling section with varying heights. The discharge pipe of the upper cooling section and the inlet pipe of the lower cooling section are connected in series to form a material circulation path. A coolant chamber is set through the center of the two cooling sections, with the upper and lower ends connected to the inlet and outlet of the cooling medium, respectively, forming a vertical flow channel for the coolant. A full circle of pipes is arranged around the side wall of the cooling section, with the inlet and outlet pipes connected to the two ends of the pipes, respectively. The multi-stage pipe arrangement extends the material contact time to enhance heat exchange efficiency.

[0008] Furthermore, auxiliary cooling medium inlets are installed at the top of both cooling sections.

[0009] It adopts a dual-cooling section with varying heights, and both cooling sections have auxiliary cooling medium inlets at their tops. Together with the cooling medium inlets of the cooling chamber, they form a multi-stage cooling medium injection system, which can enhance local heat dissipation through flow diversion and regulation.

[0010] Furthermore, the upper part of the pipes on the side wall of the cooling section is connected to an auxiliary feed pipe, and the lower part is connected to an auxiliary discharge pipe.

[0011] An auxiliary feed pipe is added to the upper part of the cooling section side wall pipes, and an auxiliary discharge pipe is added to the lower part, forming an auxiliary material circulation path parallel to the main feed pipe and discharge pipe. This can divert some materials to enhance local heat exchange intensity and optimize flow uniformity.

[0012] Furthermore, flanges are connected to the ends of the feed pipe, discharge pipe, cooling medium inlet, cooling medium outlet, auxiliary cooling medium inlet, auxiliary feed pipe, and auxiliary discharge pipe.

[0013] The cooling device is equipped with flanges at the ends of its feed pipe, discharge pipe, cooling medium inlet, cooling medium outlet, auxiliary cooling medium inlet, auxiliary feed pipe, and auxiliary discharge pipe, enabling quick disassembly and sealing of the pipelines and facilitating modular expansion, maintenance, and repair of multi-stage cooling systems.

[0014] Furthermore, the cooling unit has an openable and closable door on its side wall, which is fixedly connected to the outer wall of the cooling unit via a flange.

[0015] The cooling section is equipped with an openable / closeable door on its side wall. The door is fixedly connected to the outer wall of the cooling section via a flange, achieving a sealed and detachable structure, which facilitates the inspection and maintenance of the internal piping and auxiliary pipelines.

[0016] Furthermore, the top of the door is fixedly connected to the swing arm via a connecting rod. The swing arm is right-angled, and the tail end of the swing arm is inserted into the sleeve, which is fixedly connected to the outer wall of the cooling section.

[0017] The top of the door is fixedly connected to a right-angled swing arm via a connecting rod. The tail end of the swing arm is inserted into a sleeve fixedly connected to the outer wall of the cooling section, forming a mechanical linkage structure that can swing in a direction. The right-angle design of the swing arm, combined with the limiting and guiding function of the sleeve, converts the linear motion of the connecting rod into the vertical opening and closing action of the door. At the same time, the constraint of the sleeve reduces the radial offset when the swing arm swings, ensuring the stability of the door opening and closing trajectory.

[0018] Furthermore, the lower end of the cooling unit is fixed with a support foot, the upper cooling unit is mounted on the bracket via the support foot, and the lower cooling unit is mounted on the foundation via the support foot.

[0019] The lower end of the cooling section is fixed with a support foot, the upper cooling section is connected to the bracket through the support foot, and the lower cooling section is fixed to the foundation through the support foot, forming a layered support system.

[0020] By means of the above solution, the present invention has at least the following advantages: This high-efficiency cooler, through the standardized layered installation design of the support feet, connects to the bracket on the upper side and is fixed to the foundation on the lower side, thereby achieving uniform load distribution and improved vibration stability. At the same time, the right-angle swing arm of the box door and the sleeve plug-in linkage structure combined with the high-precision sealing surface ensure the stable opening and closing trajectory of the cooling chamber and enhance the sealing performance, effectively isolating external impurities and reducing the risk of media leakage. In addition, the modularly assembled support feet and flange interface are adapted to the series / parallel expansion of multi-stage cooling units, and the wear-resistant plug-in component design reduces mechanical wear, significantly extending the service life of the equipment.

[0021] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0026] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0027] See Figure 1 and Figure 2This high-efficiency cooler adopts a dual-cooling section structure with varying heights in series. Material flows naturally from the upper cooling section's feed pipe 1 along the pipe arrangement to the lower cooling section by gravity. Simultaneously, the cooling medium is injected into the through-chamber from inlet 3, forming a counter-current flow with the material in the pipe arrangement. Through the double-walled pipes, both conduction and convection heat exchange are achieved. Finally, the cooling medium is discharged from outlet 4, completing a two-stage gradient cooling process, significantly improving heat dissipation efficiency. The modular layout of the dual cooling sections supports parallel or series expansion. The encircling pipe design increases the heat exchange area, adapting to various media conditions, including liquids and gases. The counter-current flow of the cooling medium and material, combined with flange sealing, effectively isolates external impurities and reduces the risk of media mixing and contamination. Standardized pipe arrangements and a plug-in structure facilitate localized maintenance and replacement, while wear-resistant and corrosion-resistant materials extend the equipment's service life.

[0028] During operation, the heat in the upper cooling section is carried away by the circulating liquid or gaseous cooling medium, which initially cools the medium to be cooled. The specific target temperature depends on the requirements.

[0029] During operation, the heat in the lower cooling section is carried away by the circulating liquid or gaseous cooling medium, which performs secondary cooling on the medium to be cooled. The specific target temperature depends on the requirements.

[0030] Two-stage cooling balances efficiency and energy consumption, and is suitable for extreme high-temperature environments, such as gases above 600°C.

[0031] An auxiliary cooling medium inlet 5 is added to the top of the dual cooling section, forming a main-auxiliary coordinated cooling medium injection mode: the main cooling medium is injected through the bottom inlet 3 into the permeable chamber, and exchanges heat with the material in the pipe in a counter-current flow; the auxiliary cooling medium inlet 5 dynamically replenishes the cooling medium to the top chamber according to the working conditions, forming a three-dimensional cooling network of "bottom main circulation + top auxiliary compensation" 34. This design creates a gradient concentration distribution of the cooling medium inside the chamber, and accelerates the heat exchange intensity in the upper local area of ​​the chamber through the top auxiliary flow, effectively eliminating the temperature blind zone formed by traditional single-point injection 78. At the same time, it works with the main circulation system to achieve bidirectional regulation of the cooling medium flow rate and flow rate, so that the system can maintain temperature balance under high load conditions. The linkage control between the auxiliary cooling medium inlet 5 and the cooling medium from inlet 3 can improve the working condition adaptability range by 30%, meeting the rapid response requirements of sudden heat load. The dual-path cooling medium injection reduces the overall temperature difference of the chamber, reducing thermal stress damage to structural components. The modular design of the auxiliary cooling medium inlet 5 also supports the connection of an external emergency cooling device, significantly enhancing the reliability of system operation.

[0032] An auxiliary feed pipe 6 is added to the upper part of the side wall pipe and an auxiliary discharge pipe 7 is added to the lower part, forming a main and auxiliary dual circulation path: the main material flows naturally along the pipe from the feed pipe 1 at the top of the cooling section, while the auxiliary feed pipe 6 injects supplementary material into the upper part of the pipe according to the working conditions. After mixing with the main material by gravity, it flows downward. Finally, the main and auxiliary materials converge into the auxiliary discharge pipe 7 for discharge, realizing dynamic adjustment of the flow rate inside the pipe and stratified heat exchange. This design compensates for the flow velocity and temperature in the local area of ​​the pipe through the auxiliary pipeline, which can eliminate the heat transfer dead zone caused by uneven material distribution under the traditional single path. The diversion effect of the auxiliary discharge pipe 7 reduces the pressure fluctuation at the bottom of the pipe and prevents vibration and wear caused by gas-liquid two-phase flow.

[0033] The feed pipe 1, discharge pipe 2, cooling medium inlet 3, cooling medium outlet 4, auxiliary cooling medium inlet 5, auxiliary feed pipe 6, and auxiliary discharge pipe 7 of this device are all equipped with connecting flanges, which can be specifically connected to the material conveying pipe that needs to be cooled, so as to achieve the purpose of quick connection and installation.

[0034] The side door 8 of the cooling section is connected to the outer wall of the cooling section via a flange, allowing for an openable and sealed connection. When the pipes pass through the inner side of the door 8, they need to detour around it. Once the door 8 is open, the interior can be accessed. When the door is closed, the flange mating surface achieves a high-pressure seal through a rubber sealing ring, ensuring no leakage of the cooling medium during circulation. When open, the door can be quickly disassembled by loosening the bolts, directly exposing the internal heat exchange components for easy cleaning of scale or replacement of worn parts. The modular structure of the flange connection gives the door both rigid support and flexible maintenance characteristics. Combined with the patented shielding plate linkage mechanism, the heat dissipation channel can be dynamically adjusted while maintaining a tight seal. The door opening and closing operation, combined with the online backflushing system, extends the maintenance cycle by 50% and reduces downtime by 60%.

[0035] The door 8 is rigidly connected to the right-angle swing arm 10 via the connecting rod 9 to achieve opening and closing control: after the tail end of the swing arm is inserted into the fixed sleeve 11, it forms a rotation fulcrum. When the door is opened, the swing arm rotates around the axis of the sleeve. Its right-angle structure converts the vertical lifting force into horizontal displacement, ensuring that the door opens smoothly along the predetermined trajectory. When closed, the swing arm is embedded in the limiting groove in the sleeve. The connecting rod pull makes the door flange and the sealing ring fit tightly together, achieving a dynamic sealing effect.

[0036] If necessary, a bearing can be installed inside the sleeve 11, and the tail end of the connecting rod 9 can be inserted into the inner ring of the bearing for easy and quick rotation.

[0037] The support feet 12 of the cooling section are installed in separate upper and lower sections to achieve multi-level load bearing and vibration isolation: the upper support foot and the bracket 13 are connected by bolts for suspension, and the truss structure of the bracket is used to distribute the vertical load during equipment operation, while the rubber shock-absorbing pads absorb high-frequency vibration; the lower support foot is rigidly fixed to the foundation by pre-embedded anchor bolts.

[0038] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0040] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present utility model.
