Description

Technical Field

[0001] This utility model belongs to the technical field of cooling structure of coating machine, and specifically relates to a cooling circulation mechanism for coating machine. Background Technology

[0002] In the field of vacuum coating, the heat dissipation and cooling effect of the coating machine cavity directly affects the coating quality and equipment stability. Traditional coating machine cooling structures have many shortcomings: Single air-cooled type: These types typically have simple heat dissipation fins on the outside of the cavity, relying on natural wind or ordinary fans for heat dissipation. However, heat needs to be conducted from the inside of the cavity through the wall thickness to the external fins, resulting in a long path and high thermal resistance. If the cavity's heating power is slightly high, heat accumulation is likely to occur, leading to large temperature fluctuations inside the cavity. This cannot meet the temperature stability requirements of high-precision coating. Furthermore, the fins are prone to dust accumulation, and the heat dissipation efficiency decreases significantly after long-term use, requiring frequent maintenance.

[0003] Single water-cooled type: often adopts an external water cooling jacket or an internal flow channel design. The external water cooling jacket requires a large space to be reserved in the cavity, which occupies the volume of the equipment and is not suitable for miniaturized and integrated coating equipment. Although the internal flow channel improves the heat dissipation efficiency, it is difficult to process. If there are sand holes or aging of the sealing ring in the flow channel, the coolant can easily seep into the cavity, contaminating the cavity and the coated parts, causing the coating to be scrapped. The maintenance cost is high and the risk is great.

[0004] Simple composite cooling type: Some devices use a simple combination of air cooling and water cooling, such as an external water cooling jacket with a finned fan. However, the heat must first pass through the cavity wall to the water cooling jacket and then to the fins, which makes the conduction path longer and reduces the heat dissipation efficiency. At the same time, there are still problems such as large space occupation and uneven local temperature control, making it difficult to adapt to complex heat dissipation scenarios.

[0005] In summary, the cooling effect and temperature control accuracy of traditional cooling structures are insufficient to meet the stringent cooling requirements of high-precision vacuum coating. Utility Model Content

[0006] The purpose of this invention is to provide a cooling circulation mechanism for a coating machine, which has the advantages of good cooling effect and high temperature control accuracy.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cooling circulation mechanism for a coating machine, comprising a coating machine cavity, a cover symmetrically fixedly connected to the surface of the coating machine cavity, a plurality of equidistantly arranged arc-shaped heat dissipation fins between the cover and the coating machine cavity, a heat-conducting connecting column integrally machined on the arc-shaped heat dissipation fins, an arc-shaped heat-conducting plate symmetrically arranged inside the coating machine cavity, one end of the heat-conducting connecting column penetrating into the interior of the coating machine cavity and fixedly connected to the arc-shaped heat-conducting plate, an air guiding mechanism provided on the surface of the cover, a circulating water channel opened inside the arc-shaped heat-conducting plate, a circulating cooling water inlet pipe and a circulating cooling water outlet pipe respectively installed on the surface of the arc-shaped heat-conducting plate, the circulating cooling water inlet pipe and the circulating cooling water outlet pipe respectively communicating with both ends of the circulating water channel, and the other ends of the circulating cooling water inlet pipe and the circulating cooling water outlet pipe both penetrating to the outside of the cover.

[0008] The above technical solution involves directly attaching an arc-shaped heat-conducting plate to the inside of the coating machine cavity, which can quickly absorb heat from the cavity. The heat is efficiently transferred to the arc-shaped heat dissipation fins via the heat-conducting connecting pillars. Simultaneously, the circulating water channel inside the arc-shaped heat-conducting plate actively absorbs heat through coolant circulation, forming a dual high-efficiency heat dissipation path of internal water cooling and through-type fin air cooling. Compared with the traditional single cooling structure, the heat conduction path is shortened, and the heat dissipation efficiency is greatly improved, which can quickly remove the heat accumulated in the cavity. The tight fit between the arc-shaped heat-conducting plate and the inside of the cavity allows for uniform heat dissipation. The continuous circulation of coolant in the circulating water channel can stably absorb heat. Combined with the air cooling auxiliary adjustment of the arc-shaped heat dissipation fins, the temperature fluctuation range inside the cavity is effectively reduced, making the cavity temperature more stable and meeting the strict requirements of high-precision coating processes for temperature stability. This is beneficial for improving the uniformity and quality of the film layer.

[0009] The present invention is further configured such that the coating machine cavity is composed of two symmetrically arranged arc-shaped chambers, and the two arc-shaped chambers are hinged together, and the two covers are respectively installed on opposite sides of the two arc-shaped chambers.

[0010] The above technical solution facilitates the opening of the coating machine cavity, allowing materials to be placed inside the cavity and making loading and unloading easier.

[0011] The present invention is further configured such that the air guiding mechanism includes an air guiding seat fixedly installed on the surface of the cover, the air guiding seat is connected to the interior of the cover, and a plurality of equally spaced exhaust fans are assembled inside the air guiding seat.

[0012] The above technical solution involves an air guide mechanism where the air guide seat is connected to the inside of the housing. Multiple exhaust fans inside the mechanism can form a directional airflow. The exhaust action of the exhaust fans accelerates the airflow inside the housing, causing the hot air around the arc-shaped heat dissipation fins to be quickly drawn away and discharged from the housing. At the same time, it promotes the entry of external cold air into the housing through the air inlet slot, forming a continuous air circulation convection. This structure enhances the efficiency of air cooling. By increasing the airflow velocity, it accelerates the heat exchange between the arc-shaped heat dissipation fins and the air. Combined with the water cooling system, it further improves the overall cooling effect, ensuring that heat is dissipated from the cavity in a timely manner and maintaining the stable temperature of the coating machine cavity.

[0013] The present invention is further configured such that air inlet slots are symmetrically formed on the surface of the cover, and a dustproof net is installed inside the air inlet slots.

[0014] The above technical solution is adopted: the symmetrical air intake slots on the surface of the cover are the channels for external cold air to enter the interior of the cover, which can replenish fresh cold air for the air-cooling system. Together with the exhaust fan of the air guide mechanism, it forms a complete air circulation path, ensuring that air flows continuously through the arc-shaped heat dissipation fins, ensuring the continuity and efficiency of air-cooling heat dissipation. The dustproof net installed in the air intake slot can effectively block dust and impurities in the air from entering the interior of the cover, and prevent dust from adhering to the surface of the arc-shaped heat dissipation fins.

[0015] The present invention is further configured such that a through-hole groove is formed on the surface of the arc-shaped cavity, and the through-hole groove is used in conjunction with the heat-conducting connecting post.

[0016] The above technical solution utilizes through-hole grooves on the surface of the arc-shaped chamber in conjunction with thermally conductive connecting pillars. Its core functions lie in two aspects: the construction of a heat conduction channel and structural sealing adaptation. Firstly, the through-hole grooves provide a precise installation and through-path for the thermally conductive connecting pillars, enabling them to stably connect the arc-shaped heat-conducting plate inside the chamber to the arc-shaped heat dissipation fins outside the chamber. This forms a heat transfer channel where heat absorbed inside the chamber is transferred to the connecting pillars and then to the external fins for heat dissipation. This ensures that the heat absorbed by the arc-shaped heat-conducting plate inside the chamber is efficiently transferred to the external air-cooling structure, preventing heat accumulation at the chamber walls. Secondly, the matching structure of the through-hole grooves and thermally conductive connecting pillars, typically used in conjunction with sealing components, ensures heat conduction while preventing leakage of the vacuum environment inside the chamber due to the presence of the grooves. This balances heat transfer efficiency and chamber vacuum sealing, ensuring that the vacuum conditions and cooling effects required for the coating process are achieved simultaneously.

[0017] The present invention is further configured such that a base is provided at the bottom of the coating machine cavity, and the boss of the base is fixedly connected to the bottom of one of the arc-shaped chambers of the coating machine cavity.

[0018] The above technical solution has the following advantages: First, the base is fixedly connected to one of the arc-shaped chambers through the boss, which can provide a stable support foundation for the entire coating machine cavity. Second, the fixing method is compatible with the design of the double arc-shaped chamber hinge, so that the fixed side arc-shaped chamber becomes the reference support end for the opening and closing of the cavity, and the other side arc-shaped chamber can rotate stably around the hinge axis to open and close, avoiding the cavity from shaking due to the lack of a fixed reference during the opening and closing process, thus taking into account both the convenience of operation and the reliability of the structure.

[0019] In summary, this utility model has the following beneficial effects: 1. This utility model uses an arc-shaped heat-conducting plate to directly adhere to the inside of the coating machine cavity, which can quickly absorb heat from the cavity. The heat is efficiently transferred to the arc-shaped heat dissipation fins through the heat-conducting connecting column. At the same time, the circulating water channel inside the arc-shaped heat-conducting plate actively absorbs heat through the circulation of coolant, forming a dual high-efficiency heat dissipation path of internal water cooling heat absorption and through-type fin air cooling heat dissipation. Compared with the traditional single cooling structure, the heat conduction path is shortened, the heat dissipation efficiency is greatly improved, and the heat accumulated in the cavity can be quickly removed. 2. This utility model uses an arc-shaped heat-conducting plate that fits tightly into the cavity, allowing for uniform heat dissipation. The coolant in the circulating water tank continuously circulates, stabilizing heat absorption. Combined with the air-cooled auxiliary adjustment of the arc-shaped heat dissipation fins, it effectively reduces the temperature fluctuation range within the cavity, making the cavity temperature more stable. This meets the stringent temperature stability requirements of high-precision coating processes and helps improve the uniformity and quality of the coating layer. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Example 1: refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A cooling circulation mechanism for a coating machine includes a coating machine cavity 1. A cover 2 is symmetrically fixedly connected to the surface of the coating machine cavity 1. Multiple equidistant arc-shaped heat dissipation fins 3 are arranged between the cover 2 and the coating machine cavity 1. Heat-conducting connecting columns 4 are integrally machined onto the arc-shaped heat dissipation fins 3. Arc-shaped heat-conducting plates 5 are symmetrically arranged inside the coating machine cavity 1. One end of the heat-conducting connecting column 4 penetrates into the interior of the coating machine cavity 1 and is fixedly connected to the arc-shaped heat-conducting plate 5. An air guiding mechanism 6 is provided on the surface of the cover 2. A circulating water channel 7 is opened inside the arc-shaped heat-conducting plate 5. A circulating cooling water inlet pipe 8 and a circulating cooling water outlet pipe 9 are respectively installed on the surface of the arc-shaped heat-conducting plate 5. The circulating cooling water inlet pipe 8 and the circulating cooling water outlet pipe 9 are respectively connected to both ends of the circulating water channel 7. The other ends of the circulating cooling water inlet pipe 8 and the circulating cooling water outlet pipe 9 both penetrate to the outside of the cover 2. The curved heat-conducting plate 5 is directly attached to the inside of the coating machine cavity 1, which can quickly absorb heat from the cavity. The heat is efficiently transferred to the curved heat dissipation fins 3 via the heat-conducting connecting column 4. At the same time, the circulating water channel 7 inside the curved heat-conducting plate 5 actively absorbs heat through the circulation of coolant, forming a dual high-efficiency heat dissipation path of internal water cooling heat absorption and through-type fin air cooling heat dissipation. Compared with the traditional single cooling structure, the heat conduction path is shortened and the heat dissipation efficiency is greatly improved, which can quickly remove the heat accumulated in the cavity. Because the curved heat-conducting plate 5 is closely attached to the inside of the cavity, it can dissipate heat evenly in the cavity. The coolant in the circulating water channel 7 continuously circulates and can stably absorb heat. With the air cooling auxiliary adjustment of the curved heat dissipation fins 3, the temperature fluctuation range in the cavity is effectively reduced, making the cavity temperature more stable and meeting the strict requirements of temperature stability for high-precision coating processes. This is beneficial to improving the uniformity and quality of the film layer.

[0024] refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 The coating machine cavity 1 consists of two symmetrically arranged arc-shaped chambers 10, which are hinged together. Two covers 2 are installed on opposite sides of the two arc-shaped chambers 10. By setting the arc-shaped chambers 10, the coating machine cavity 1 can be opened easily, so that materials can be put into the cavity of the coating machine cavity 1, which is convenient for loading and unloading.

[0025] refer to Figure 1The air guiding mechanism 6 includes an air guiding seat 61 fixedly installed on the surface of the cover 2. The air guiding seat 61 is connected to the interior of the cover 2. Multiple equidistant exhaust fans 62 are installed inside the air guiding seat 61. By setting the air guiding seat 61 and the exhaust fans 62, the air guiding mechanism 6 connects the air guiding seat 61 to the interior of the cover 2. The multiple exhaust fans 62 inside can form a directional airflow. Through the exhaust action of the exhaust fans 62, the air flow inside the cover 2 can be accelerated, so that the hot air around the arc-shaped heat dissipation fins 3 is quickly drawn away and discharged from the cover 2. At the same time, it promotes the external cold air to enter the cover 2 through the air inlet slot 11, forming a continuous air circulation convection. This structure enhances the efficiency of air cooling. By increasing the air flow rate, the heat exchange between the arc-shaped heat dissipation fins 3 and the air is accelerated. Combined with the water cooling system, the overall cooling effect is further improved, ensuring that the heat is dissipated from the cavity in time and maintaining the temperature stability of the coating machine cavity 1.

[0026] refer to Figure 1 and Figure 2 The surface of the cover 2 is symmetrically provided with air inlet slots 11, and the inside of the air inlet slots 11 is equipped with a dustproof net 12. By setting the air inlet slots 11 and the dustproof net 12, the symmetrical air inlet slots 11 on the surface of the cover 2 are channels for external cold air to enter the inside of the cover 2, which can replenish fresh cold air to the air-cooling system. Together with the exhaust fan 62 of the air guide mechanism 6, a complete air circulation path is formed to ensure that air flows continuously through the arc-shaped heat dissipation fins 3, ensuring the continuity and efficiency of air-cooling heat dissipation. The dustproof net 12 installed in the air inlet slots 11 can effectively block dust and impurities in the air from entering the inside of the cover 2, and prevent dust from adhering to the surface of the arc-shaped heat dissipation fins 3.

[0027] refer to Figure 6 The surface of the arc-shaped chamber 10 is provided with a through-hole groove 13, which is used in conjunction with the heat-conducting connecting post 4. By setting the through-hole groove 13, the core functions of the through-hole groove 13 on the surface of the arc-shaped chamber 10 and the heat-conducting connecting post 4 are reflected in two aspects: the construction of a heat conduction channel and the structural sealing adaptation. On the one hand, the through-hole groove 13 provides a precise installation and through path for the heat-conducting connecting post 4, so that the heat-conducting connecting post 4 can stably connect the arc-shaped heat-conducting plate 5 inside the chamber and the arc-shaped heat dissipation fins 3 outside the chamber, forming a heat transfer channel from the heat absorbed inside the chamber to the connecting post and then to the heat dissipation of the external fins. This ensures that the heat absorbed by the arc-shaped heat-conducting plate 5 inside the chamber is efficiently transferred to the external air-cooling structure, avoiding heat accumulation at the chamber wall. On the other hand, the adaptation structure of the through-hole groove 13 and the heat-conducting connecting post 4 is usually used in conjunction with a sealing element. This can ensure heat conduction while preventing leakage of the vacuum environment inside the chamber due to the presence of the groove, balancing heat transfer efficiency and chamber vacuum sealing, and ensuring that the vacuum conditions and cooling effect required for the coating process are achieved simultaneously.

[0028] refer to Figure 1 and Figure 3The bottom of the coating machine cavity 1 is provided with a base 14. The boss of the base 14 is fixedly connected to the bottom of one of the arc-shaped chambers 10 of the coating machine cavity 1. By setting the base 14, on the one hand, the base 14 is fixedly connected to one of the arc-shaped chambers 10 through the boss, which can provide a stable support foundation for the entire coating machine cavity 1. On the other hand, this fixing method is adapted to the hinged design of the double arc-shaped chambers 10, so that the fixed side arc-shaped chamber 10 becomes the reference support end for the opening and closing of the cavity, and the other side arc-shaped chamber 10 can be stably rotated and opened and closed around the hinge axis, avoiding the cavity from shaking due to the lack of a fixed reference during the opening and closing process, thus taking into account both the convenience of operation and the reliability of the structure.

[0029] Brief Description of Usage: This utility model achieves efficient cooling of the coating machine cavity 1 through the synergistic effect of water-cooled heat absorption and air-cooled heat dissipation. During operation, after the internal temperature of the coating machine is detected by an external temperature sensor, the working principle can be summarized in three steps: First, the heat generated by the coating machine cavity 1 during operation is directly captured by the arc-shaped heat-conducting plate 5 attached to the inner wall of the cavity. Simultaneously, the coolant circulating in the water tank 7 inside the arc-shaped heat-conducting plate 5 quickly absorbs the heat on the heat-conducting plate, completing the initial transfer of heat from the cavity to the coolant. Second, the arc-shaped heat-conducting plate 5 is not cooled... Part of the heat absorbed by the liquid is transferred to the arc-shaped heat dissipation fins 3 outside the cavity through the heat-conducting connecting column 4 that runs through the arc-shaped cavity 10. This transfers the heat to the air-cooled area outside the cavity. The exhaust fan 62 in the air guide mechanism 6 starts and draws air from inside the cover 2 through the air guide seat 61. This causes the external cold air to enter the cover 2 through the air inlet slot 11, forming a continuous airflow that flows through the arc-shaped heat dissipation fins 3. This quickly carries away the heat on the fins and discharges it from the cover 2. At the same time, the coolant flows out of the cavity through the circulating cooling drain pipe 9, completing the final heat transfer and achieving stable temperature control of the cavity.

[0030] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0031] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
