Description
Technical Field
[0001] This utility model relates to the technical field of vacuum cavity cooling devices, specifically a vacuum cavity cooling device with a protective structure. Background Technology
[0002] A vacuum chamber is a sealed space formed in a vacuum. In the semiconductor industry, vacuum chambers are used to manufacture high-precision devices such as integrated circuits and liquid crystal displays to isolate the external environment from the process. Furthermore, vacuum chambers play an indispensable role in fields such as vacuum coating and solar cell manufacturing.
[0003] Currently, most vacuum chambers on the market are made of stainless steel, and their external cooling is mostly achieved using water-cooled coils to ensure that the internal working conditions are low. However, this approach has some functional shortcomings and room for improvement. For example, the coil, as the main component for cooling, has a limited contact area with the vacuum chamber, leaving room for further improvement in cooling performance. Furthermore, the protective shell on the outside of the coil is directly attached to the outside of the coil, so when the shell is bumped or dented, the coil will also be dented directly, resulting in poor protection performance and failing to enhance cooling performance or improve protection.
[0004] Now, a novel vacuum cavity cooling device with a protective structure is proposed to solve the above problems. Utility Model Content

[0009] Preferably, the second top protective shell and the second bottom protective shell coincide with the vertical center line of the vacuum chamber body, and the second top protective shell and the second bottom protective shell have the same size.
[0010] Preferably, the aluminum alloy fins are arranged at equal intervals, and the interior of the aluminum alloy fins is uniformly provided with holes, and the vacuum chamber body and the aluminum alloy fins are connected.
[0011] Preferably, a sensor mounting bracket is fixedly connected to one side of the water inlet pipe, a temperature sensor is inserted into the top of one side of the sensor mounting bracket, a PLC controller is fixedly connected to the bottom of one side of the sensor mounting bracket, and a speaker is installed on one side of the PLC controller.

The interior of the aluminum alloy fins 9 is uniformly provided with holes. The connection between the vacuum chamber body 2 and the aluminum alloy fins 9 can improve cooling efficiency and increase protection performance.
[0028] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the first bottom protective shell 3, the first top protective shell 4, the second top protective shell 5, the second bottom protective shell 6, the third bottom protective shell 10, and the third top protective shell 11 form a cylindrical external protection. The aluminum alloy fins 9 serve as an external extension of the cooling coil 8, increasing the contact surface with the vacuum chamber body 2 and allowing the temperature of the surface of the vacuum chamber body 2 to be discharged outward. They also form a support between the external protection and the vacuum chamber body 2, protecting the internal cooling coil 8 when the external protection is recessed.
[0029] Example 2: A sensor mounting bracket 13 is fixedly connected to one side of the water inlet pipe 7. A temperature sensor 15 is inserted into the top of one side of the sensor mounting bracket 13. A PLC controller 14 is fixedly connected to the bottom of one side of the sensor mounting bracket 13. A speaker 16 is installed on one side of the PLC controller 14.

The PLC controller 14, the temperature sensor 15, and the speaker 16 are electrically connected, which can monitor the inlet water temperature and avoid insufficient cooling effect caused by abnormal operation of the chiller.
[0030] Specifically, such as Figure 1 and Figure 3 As shown, the temperature sensor 15 on one side of the sensor mounting bracket 13 measures the temperature of the cold water in the inlet pipe 7 in real time and feeds the data back to the PLC controller 14. The PLC controller 14 controls the speaker 16 according to the data fed back by the temperature sensor 15. When the temperature is abnormal, it can issue a prompt voice to remind the staff to check whether the chiller is working abnormally.
[0031] Example 3: The top of the third top protective shell 11 is fixedly connected to the first fan mounting base 17, and the top of the first fan mounting base 17 is equipped with an exhaust fan 18.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, the exhaust fan 18 on the first fan mounting base 17 starts to draw the air out from between the vacuum chamber body 2 and its external protection, while the blower 20 on the second fan mounting base 19 sends in the external cold air. The combination of extraction and delivery accelerates the airflow speed between the vacuum chamber body 2 and its external protection, improves the heat dissipation efficiency of the aluminum alloy fins 9, and further enhances its cooling effect.
[0033] Working principle: When this utility model is in use, firstly, the bottom support frame 1 serves as the bottom support. The production and processing process is completed inside the vacuum chamber body 2. During the operation of the vacuum chamber, the chiller pumps cold water in from the inlet pipe 7 and recovers it from the outlet pipe 12, forming a cold water circulation. The cooling coil 8 cools the vacuum chamber body 2. The first bottom protective shell 3, the first top protective shell 4, the second top protective shell 5, the second bottom protective shell 6, the third bottom protective shell 10, and the third top protective shell 11 form a cylindrical external protection. The aluminum alloy fins 9 serve as an external extension of the cooling coil 8, increasing the contact surface with the vacuum chamber body 2 and allowing the heat from the surface of the vacuum chamber body 2 to be discharged outwards. They also form a support between the external protection and the vacuum chamber body 2. When the external protection is recessed, it can protect the internal cooling coil 8. The chiller pumps chilled water into the inlet pipe 7. A temperature sensor 15 on one side of the sensor mounting bracket 13 measures the temperature of the chilled water in the inlet pipe 7 in real time and feeds the data back to the PLC controller 14. The PLC controller 14 controls the speaker 16 based on the data from the temperature sensor 15, issuing a warning voice when the temperature is abnormal, reminding staff to check if the chiller is malfunctioning. Simultaneously with the water cooling process, the exhaust fan 18 on the first fan mounting base 17 starts, drawing air out from between the vacuum chamber body 2 and its external protection. Meanwhile, the blower 20 on the second fan mounting base 19 delivers external cold air. This extraction and delivery accelerates the airflow between the vacuum chamber body 2 and its external protection, improving the heat dissipation efficiency of the aluminum alloy fins 9 and further enhancing the cooling effect.
