Description

Technical Field

[0001] The present invention relates to the technical field of fluid cooling, and more specifically, to a two-phase high-efficiency cooling device. Background Art

[0002] Cooling equipment is particularly important in the industry and trade, especially during the gear rotation process. Cooling equipment can effectively control the heat generated by the gear system when it is working, and maintain the lubricating oil at a suitable working temperature to prevent the lubricating oil temperature from being too high, which may lead to the degradation of gear material performance, increased tooth surface wear, and deterioration of lubricating oil performance. At the same time, cooling equipment can also control the lubricating oil to remain within the appropriate temperature range, thereby ensuring that the lubricating oil has good viscosity and lubricating properties, reducing friction and wear between gears, avoiding thermal deformation of gears due to overheating, extending the service life of gears and bearings, ensuring the accuracy and stability of gear transmission, and improving transmission efficiency and working reliability.

[0003] Cooling equipment also plays an important role in hydraulic systems. For example, cooling equipment can ensure that the hydraulic oil works within a suitable temperature range, thereby preventing the hydraulic oil temperature from being too high, which may cause the hydraulic oil to deteriorate and reduce viscosity, affecting the performance and reliability of the hydraulic system. At the same time, cooling equipment can also solve the problem of too high hydraulic oil temperature, avoid thermal damage to hydraulic components (such as pumps, valves, seals, etc.) caused by high hydraulic oil temperature, reduce wear and failure of hydraulic components, extend the service life of the hydraulic system, and reduce maintenance costs.

[0033] The present invention provides a two-phase high-efficiency cooling device. In the present invention, the two-phase high-efficiency cooling device includes three main parts: 1. A structure for providing cold capacity, including a refrigerator and a cold source heat exchange tube 1 for unidirectionally transporting cooling water that transports cold capacity; 2. A structure for transporting a medium to be cooled, including a pump and a cooling heat exchange tube 2 for unidirectionally transporting the medium to be cooled; 3. A structure for realizing cold capacity exchange, including a slow-flow cooling box 3, the interior of the slow-flow cooling box 3 is used to load cooling water, the cold source heat exchange tube 1 and the cooling heat exchange tube 2 are both arranged through the slow-flow cooling box 3, and the cold source heat exchange tube 1 and the cooling heat exchange tube 2 are loaded with cooling water in the slow-flow cooling box 3 to exchange cold capacity to form a two-phase high-efficiency heat exchange structure.

[0034] In the above structural design, the cold source heat exchange tube 1 contacts the cooling water loaded inside the slow flow cooling box 3, thereby exchanging cold energy into the cooling water to reduce the temperature of the cooling water, and the cooling heat exchange tube 2 contacts the cooling water loaded inside the slow flow cooling box 3, and can absorb the cold energy of the cooling water, thereby achieving the purpose of cooling. The present invention mainly realizes cold energy exchange through the cooling water loaded in the slow flow cooling box 3. In order to improve the cold energy release efficiency of the cold source heat exchange tube 1 and improve the cold energy absorption efficiency of the cooling heat exchange tube 2, the present invention also provides a high-efficiency heat dissipation cooling plate 4, which is a double-layer structure. The double-layer structure of the high-efficiency heat dissipation cooling plate 4 is clamped on the cold source heat exchange tube 1 or the cooling heat exchange tube 2. Specifically, the cold source heat exchange tube 1 contacts the high-efficiency heat dissipation cooling plate 4 and forms a heat conduction connection structure, and the cold source heat exchange tube 1 and the high-efficiency heat dissipation cooling plate 4 constitute a cold source heat exchange component; the cooling heat exchange tube 2 contacts the high-efficiency heat dissipation cooling plate 4 and forms a heat conduction connection structure, and the cooling heat exchange tube 2 and the high-efficiency heat dissipation cooling plate 4 constitute a cooling heat exchange component.

[0035] The high-efficiency heat dissipation cooling plate 4 of the present invention has two main functions: 1. increasing the contact area between the pipeline (cold source heat exchange tube 1 and cooling heat exchange tube 2) and the cooling water; 2. forming a complex flow channel structure inside the slow-flow cooling box 3 to reduce the flow rate of the cooling water in the slow-flow cooling box 3.

[0036] In a specific embodiment of the present invention, the cold source heat exchange tube 1 and the cooling heat exchange tube 2 are both metal pipes (preferably using an S-shaped coil structure), such as an aluminum tube or a copper tube or a stainless steel tube. The high-efficiency heat dissipation cooling plate 4 is a metal plate, such as an aluminum plate, a copper plate or a stainless steel plate, and the cold source heat exchange tube 1 and the cooling heat exchange tube 2 are welded to the high-efficiency heat dissipation cooling plate 4.

[0037] In another specific embodiment of the present invention, an S-shaped groove structure is provided on the high-efficiency heat dissipation cooling plate 4, two high-efficiency heat dissipation cooling plates 4 are relatively assembled together and then fixed, and an S-shaped pipe structure is formed inside the high-efficiency heat dissipation cooling plate 4, that is, the cold source heat exchange tube 1 and the cooling heat exchange tube 2 are directly formed on the high-efficiency heat dissipation cooling plate 4.

[0038] Furthermore, the cold source heat exchange components are grouped in two, the two cold source heat exchange components in the same group are arranged at intervals and in parallel, and the cold source heat exchange pipes 1 arranged in the two cold source heat exchange components in the same group are connected; the cooling heat exchange components are grouped in two, the two cooling heat exchange components in the same group are arranged at intervals and in parallel, and the cooling heat exchange pipes 2 arranged in the two cooling heat exchange components in the same group are connected; the two cold source heat exchange components in the same group and the two cooling heat exchange components in the same group are arranged in a staggered plug-in structure to form a heat exchange unit, that is, a heat exchange unit consists of two cold source heat exchange components and two cooling heat exchange components, the two cold source heat exchange components and the two cooling heat exchange components are interspersed to form a structure of cold source heat exchange component-cooling heat exchange component-cold source heat exchange component-cooling heat exchange component, which can increase the residence time of the cold air or the medium to be cooled in the slow flow cooling box 3, and improve the efficiency of cold release and cold absorption.

[0039] In the above structural design, in the same heat exchange unit, adjacent high-efficiency heat dissipation cooling plates 4 are arranged at intervals to facilitate the circulation of cooling water loaded in the slow-flow cooling box 3 .

[0040] The present invention provides a cooling water inlet for cooling water input and a cooling water outlet for cooling water output on the slow flow cooling box 3, and the cooling water inlet and the cooling water outlet are opened on the same side of the slow flow cooling box 3; and / or, the setting height of the cooling water inlet is lower than the setting height of the cooling water outlet.

[0041] As can be seen from the above, the refrigerator is connected to the cold source heat exchange tube 1 to form cold air for cold transport; the pump is connected to the cooling heat exchange tube 2 to transport the medium to be cooled. Specifically, the cold source heat exchange tube 1 is connected to a vortex refrigerator 5 for providing cold; the cooling heat exchange tube 2 is connected to a diaphragm pump 6 for transporting the medium to be cooled.

[0042] As another structural design focus of the present invention, the present invention also proposes the following structural design: the inner side of the high-efficiency heat dissipation cooling plate 4 is in contact with the cold source heat exchange tube 1 or the cooling heat exchange tube 2 (or the cold source heat exchange tube 1 or the cooling heat exchange tube 2 is formed on the inner side of the high-efficiency heat dissipation cooling plate 4), and the outer side of the high-efficiency heat dissipation cooling plate 4 is provided with a spoiler structure 7, which is used to increase the direct contact area between the high-efficiency heat dissipation cooling plate 4 and the cooling water and to disturb the transportation of the cooling water. Specifically, the spoiler structure 7 is a hexagonal honeycomb structure; the spoiler structure 7 arranged on the same side is provided with two layers. Furthermore, the outer side of the spoiler structure 7 is a smooth arc surface protruding outward. The spoiler structure 7 can be a separate structure, fixed to the outer side of the high-efficiency heat dissipation cooling plate 4, for example, fixed by glue or welding. The spoiler structure 7 can also be directly formed on the efficient heat dissipation cooling plate 4. When the efficient heat dissipation cooling plate 4 is a thin plate structure, the spoiler structure 7 can be formed on the efficient heat dissipation cooling plate 4 by stamping, and the cold source heat exchange tube 1 and the cooling heat exchange tube 2 can be welded on the efficient heat dissipation cooling plate 4 as independent structures. One side of the spoiler structure 7 is connected to the efficient heat dissipation cooling plate 4, and the other side of the spoiler structure 7 adopts an arc surface structure design, which is preferably a smooth arc surface structure protruding outward, and can also adopt an inward concave arc surface structure. The spoiler structure 7 can be a hexagonal structure, similar to a honeycomb, or a cylindrical structure. The spoiler structure 7 can adopt a single-layer structure on the efficient heat dissipation cooling plate 4, that is, only one layer of spoiler structure 7 is set on the efficient heat dissipation cooling plate 4, and a second layer, a third layer, etc. can be set on the basis of a layer of spoiler structure 7. For each layer of spoiler structure 7, the spoiler structures 7 of the same layer can be closely arranged or arranged at intervals. When two or more layers of spoiler structures 7 are provided, the spoiler structures 7 between adjacent layers are staggered.

[0043] The present invention provides a two-phase high-efficiency cooling device, which can effectively solve the problem of too high oil temperature in lubrication systems or hydraulic systems, such as splash lubrication reducers. The two-phase high-efficiency cooling device provided by the present invention specifically includes a pneumatic diaphragm pump 6 (for pumping liquids that need to be cooled, such as lubricating oil or hydraulic oil), a vortex refrigerator 5 (as a cold source, for providing cold capacity), a muffler 8 (installed on the vortex refrigerator 5, for silencing and reducing noise when discharging hot air flow), a heat dissipation cooling pipe (for air flow circulation) and a slow flow cooling box 3 (for installing a heat dissipation cooling pipe to achieve efficient exchange of cold capacity through water flow).

[0044] In a specific embodiment of the present invention, the two-phase high-efficiency cooling device provided by the present invention is a combined structure, including: a pneumatic diaphragm pump 6, a slow-flow cooling box 3, a high-efficiency heat dissipation cooling plate 4, and a vortex refrigerator 5. Among them, the high-efficiency heat dissipation cooling plate 4 is installed in the circulating cooling box, and while disturbing the cooling water (slow flow), it can also effectively improve the heat exchange efficiency between the heat dissipation cooling pipe in the plate and the cooling water. Specifically, the high-efficiency heat dissipation cooling plate 4 is evenly installed in the slow-flow cooling box 3, and a corresponding gap is left between the two high-efficiency heat dissipation cooling plates 4 to ensure the passage of cooling water.

[0045] The interior of the slow-flow cooling box 3 is designed with a special slow-flow structure, such as a high-efficiency heat dissipation cooling plate 4, other baffle-like structures, guide grooves, etc., so that the flow rate of the cooling water inside the slow-flow cooling box 3 is slowed down and a complex flow path is formed, which prolongs the residence time of the cooling water in the box and allows it to more fully exchange heat. The slow-flow cooling box 3 is preferably a rectangular box structure, which is convenient for the installation of the high-efficiency heat dissipation cooling plate 4. A cooling water inlet and a cooling water outlet are provided on the same side of the circulating cooling box. Furthermore, the cooling water outlet is arranged near the top, and the cooling water inlet is arranged near the bottom. In this way, the cooling water flows from bottom to top inside the slow-flow cooling box 3, and this flow method can improve the stability of the cooling water flowing inside the slow-flow cooling box 3.

[0046] The high-efficiency heat dissipation cooling plate 4 is a double-layer sealed structure, and the whole is made of heat-conducting materials, such as metal aluminum or aluminum alloy, stainless steel, etc. The high-efficiency heat dissipation cooling plate 4 is a plate structure, which includes two large sides, and a plurality of arc-surface honeycomb hexagonal protrusions are arranged on the side surface as spoiler structures 7. In one embodiment of the present invention, the spoiler structure 7 arranged on a single side of the high-efficiency heat dissipation cooling plate 4 is two layers, and the spoiler structures 7 in each layer can be arranged closely or at intervals. When arranged at intervals, the distance between two adjacent spoiler structures 7 is less than the minimum size of the spoiler structure 7 itself, so that the two layers of spoiler structures 7 can be stacked together. The two layers of spoiler structures 7 stacked together also adopt a staggered structure setting.

[0047] In addition to the above-mentioned structural design, the present invention may also adopt the following structure in other embodiments: the spoiler structure 7 is staggered on the high-efficiency heat dissipation cooling plate 4 (for example, the spoiler structure 7 is arranged at equal intervals laterally, and multiple rows are arranged in the height direction, and the spoiler structures 7 between two adjacent rows are staggered laterally; further, the spoiler structures 7 in the same row may also be staggered in the height direction; at the same time, the spoiler structures 7 arranged on both sides of the same high-efficiency heat dissipation cooling plate 4 are also staggered). By arranging the spoiler structure 7 on the high-efficiency heat dissipation cooling plate 4, a special flow path can be formed, which increases the heat exchange surface area of ​​the high-efficiency heat dissipation cooling plate 4 and forms a turbulent flow path for the cooling water, thereby improving the heat exchange effect.

[0048] The working process of the present invention is as follows: when the two-phase high-efficiency cooling equipment is working, the pneumatic diaphragm pump 6 is started first, and its function is to extract the medium to be cooled (such as gear oil or special fluid) from the storage container and transport it to one of the subsequent groups of high-efficiency heat dissipation cooling plates 4 for cooling; at the same time, the compressed air is turned on to enter the vortex refrigerator 5. The vortex refrigerator 5 works based on the vortex tube principle. After the compressed gas enters the vortex tube, it will rotate at high speed in the tube and separate into two cold and hot air flows. The hot air flow is discharged from one end of the vortex refrigerator 5, and is discharged into the surrounding environment after noise reduction through the muffler 8. The cold air flow is guided to another group of high-efficiency heat dissipation cooling plates 4. There are two types of high-efficiency heat dissipation cooling plates 4, one for heat exchange of the medium to be cooled, and the other for heat exchange of cold air. The two types of high-efficiency heat dissipation cooling plates 4 are alternately arranged and fixedly installed in the slow-flow cooling box 3, and corresponding gaps are left between the two types of high-efficiency heat dissipation cooling plates 4 to ensure the passage of cooling water.

[0049] When the cold airflow generated by the vortex refrigerator 5 flows in the high-efficiency heat dissipation cooling plate 4, it will exchange heat with the water in the slow-flow cooling box 3. Since the temperature of the cold airflow is lower than the temperature of the cooling water, the heat is transferred to the cold airflow, thereby reducing the temperature of the cooling water. When the pneumatic diaphragm pump 6 extracts the medium (oil) to be cooled and flows in the high-efficiency heat dissipation cooling plate 4, it will exchange heat with the cooling water in the slow-flow cooling box 3. Since the water in the slow-flow cooling box 3 has an extremely low temperature after heat exchange with the cold airflow in the high-efficiency heat dissipation cooling plate 4, the temperature of the oil to be cooled can be quickly reduced, thereby achieving efficient cooling.

[0050] As can be seen from the above, the present invention provides a two-phase high-efficiency cooling device, which includes: a cold source heat exchange tube 1 for unidirectional transportation of cooling water for transporting cold; a cooling heat exchange tube 2 for unidirectional transportation of a medium to be cooled; a slow-flow cooling box 3 for loading cooling water inside, the cold source heat exchange tube 1 and the cooling heat exchange tube 2 are both arranged through the slow-flow cooling box 3, and the cold source heat exchange tube 1 and the cooling heat exchange tube 2 are loaded with cooling water inside the slow-flow cooling box 3 to exchange cold to form a two-phase high-efficiency heat exchange structure. Through the above structural design, the present invention is loaded with cooling water inside the slow-flow cooling box 3, the cold source heat exchange tube 1 transports cold, the cold is exchanged into the cooling water, and then the cold in the cooling water is exchanged to the medium to be cooled in the cooling heat exchange tube 2, thereby realizing the cooling and temperature reduction of the medium to be cooled. The present invention has a reasonable structural design and adopts cooling water for heat exchange. The cooling water can absorb and release a large amount of cold. In addition, the residence time of the cold air and the medium to be cooled and the contact area with the cooling water can be increased by optimizing the structure of the cold source heat exchange tube 1 and the cooling heat exchange tube 2, thereby achieving the effect of improving the cooling heat exchange efficiency.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
