Description

Technical Field

[0001] This utility model relates to the field of power battery technology, and in particular to a cooling device. Background Technology

[0002] In vacuum coating equipment, the material released from the evaporation source (such as copper foil or aluminum foil) condenses on the substrate surface to form a thin film during the vacuum coating process. If the substrate temperature is too high, it will cause uneven crystallization and stress during the growth of the film, which will affect the uniformity, adhesion and performance of the film. Therefore, the substrate needs to be cooled down during the coating process. However, the cooling device in the existing vacuum coating equipment is mostly a single water pipe controlled cooling. One end of multiple single water pipes is connected to the cooling box, and the other end is extended into the vacuum chamber and close to multiple substrates to cool the substrates in real time through the flow of coolant. However, this arrangement requires a large number of water pipe joints to be connected to the cooling box, which can easily lead to multiple water pipes being tangled and affecting the use. In addition, each water pipe needs to be connected to the cooling box by a separate joint, which is costly and cumbersome to disassemble. Utility Model Content

[0003] In order to overcome at least one of the defects of the prior art, the present invention provides a cooling device having multiple outlets on its cooling pipes, connecting multiple water pipes to the multiple outlets, so that cooling water is centrally circulated and discharged into multiple water pipes.

[0004] The technical solution adopted by this utility model to solve its problem is:

[0005] A cooling device includes a cooling pipe having a flow channel, the flow channel having an inlet and a plurality of outlets, the inlet being used to guide coolant into the flow channel, and the plurality of outlets being spaced apart on the outer periphery of the cooling pipe and used to guide coolant out.

[0006] Furthermore, the cooling pipe is an annular pipe, and the plurality of outlets are evenly distributed around the circumference of the cooling pipe.

[0007] Furthermore, each of the multiple outlets is connected to a liquid outlet connector, which is in communication with the outlet and protrudes from the outer periphery of the cooling pipe.

[0008] Furthermore, it also includes multiple guide tubes, one end of which is connected and in communication with multiple liquid outlet connectors, and the other end of which is connected to an external structure.

[0009] Furthermore, the inlet is provided with an inlet connector, which is connected to the flow channel.

[0010] Furthermore, the liquid inlet connector has a first end and a second end. The first end is inserted into the liquid inlet and abuts against the inner wall of the liquid inlet. The second end is used to fit onto the outer periphery of the liquid inlet after the first end is inserted into the liquid inlet.

[0011] Furthermore, a sealing head is provided at the other end of the cooling pipe away from the liquid inlet connector, and the sealing head is used to seal the other end of the flow channel away from the liquid inlet.

[0012] Furthermore, the sealing head includes a third end and a fourth end. The third end is inserted into the flow channel, and the fourth end is used to fit onto the outer periphery of the cooling pipe after the third end is inserted into the flow channel.

[0013] Furthermore, the water pump is used to drive the coolant to flow within the flow channel.

[0014] In summary, the cooling device provided by this utility model has the following technical effects: During specific assembly, the interfaces of multiple water pipes are connected to multiple outlets on the cooling pipes respectively. In this way, only the inlet of the cooling pipe needs to be connected to the cooling box, and the coolant can circulate into multiple water pipes respectively to achieve centralized circulation cooling. There is no need for multiple joints to be connected to the cooling box separately, which reduces the number of joints, simplifies assembly, and makes it less likely for multiple water pipes to become tangled, resulting in a cleaner appearance.

[0019] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] In the description of this utility model, it should be noted that 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] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] See Figures 1 to 2 This utility model discloses a cooling device, including a cooling pipe 10. The cooling pipe 10 has a flow channel, which has an inlet 11 and multiple outlets 12. The inlet 11 is used to guide coolant into the flow channel, and the multiple outlets 12 are distributed at intervals on the outer periphery of the cooling pipe 10 and are used to guide coolant out.

[0023] Based on the above structure, when the cooling pipe 10 is connected to external equipment, the inlet 11 of the cooling pipe 10 is connected to the container holding the coolant so that the coolant is introduced into the guide channel through the inlet 11. After being introduced, the coolant is then discharged to the required branch through multiple outlets 12, so that the coolant in the cooling pipe 10 can be distributed to multiple branches at the same time for cooling multiple devices or components, reducing the use of water pipes or joints.

[0024] Because most existing vacuum coating equipment uses a single water pipe for cooling, that is, one end of multiple water pipes is connected to the cooling box, and the other end is inserted into the vacuum chamber and close to multiple substrates to cool the substrates in real time through flowing coolant. However, this arrangement requires a large number of water pipe joints to connect to the cooling box 40, which can easily lead to multiple water pipes being intertwined and affecting use. In addition, each water pipe needs a separate joint to connect to the cooling box 40, which is costly and cumbersome to disassemble.

[0025] Therefore, when the cooling pipe 10 in this embodiment is applied to the vacuum coating equipment, during assembly, the cooling pipe 10 is installed on the outside of the equipment away from the chamber, and then the liquid inlet 11 of the cooling pipe 10 is connected to the cooling box 40 through a single liquid guide pipe 41. In this way, the coolant can flow into the guide channel through the liquid inlet 11, and then flow into multiple water pipes or guide pipes through multiple outlets 12, and flow into the chamber to cool multiple substrates simultaneously. The coolant is circulated to multiple water pipes or guide pipes connected to the equipment through a single cooling pipe, realizing centralized circulation cooling. There is no need for multiple joints to be connected to the cooling box 40 separately, reducing the number of joints, simplifying assembly, and making it less likely for multiple pipes to become tangled, resulting in a simpler exterior.

[0026] In addition, by setting multiple outlets 12 on a single cooling pipe 10 and connecting it to multiple devices that need cooling at the same time, the coolant can be synchronously circulated and discharged into the interior of multiple devices that need cooling through a single cooling pipe 10 for centralized cooling and temperature reduction. Synchronous cooling and temperature reduction can reduce the temperature difference between multiple devices in the chamber, making the temperature distribution of the entire system more uniform. This helps to improve the stability and reliability of the entire system. At the same time, synchronous cooling and temperature reduction can also optimize the allocation and utilization of cooling resources and avoid unnecessary energy waste.

[0027] More specifically, it also includes a water pump. The cooling pipe 10 can be directly connected to the inlet and outlet of the water pump. During assembly, the liquid inlet 11 of the cooling pipe 10 can be inserted into the inlet and outlet of the water pump, and clamps, clamps or threaded joints or other fixing devices can be used to tighten it to ensure that the connection is firm and leak-free. The pipes connected to the multiple outlets 12 can be extended to water tanks or water towers after being connected to external equipment, so that the entire cooling system forms a loop. The water pump drives the coolant to circulate to the cooling pipe 10 and flow through multiple outlets 12 into multiple external equipment.

[0028] Furthermore, the cooling pipe 10 is an annular pipe, with multiple outlets 12 evenly distributed around the circumference of the cooling pipe 10.

[0029] Specifically, the cooling pipe 10 is arranged in a ring shape, which allows it to be arranged around the component that needs to be cooled, forming a compact loop. This design not only reduces the length of the pipes but also saves space, making the entire cooling system more compact. The ring arrangement allows the cooling pipe 10 to make more efficient use of limited space, resulting in a more practical structure.

[0030] Furthermore, when multiple outlets 12 are evenly distributed around the circumferential spacing of the cooling pipe 10, the cooling medium (such as water or coolant) can flow more evenly through the entire cooling pipe 10, thereby achieving uniform heat dissipation of the cooling pipe 10 and its surrounding components.

[0031] Furthermore, each of the multiple outlets 12 is connected to a liquid outlet connector 30, which connects the liquid outlet connector 30 to the outlet 12 and protrudes from the outer periphery of the cooling pipe 10.

[0032] Specifically, multiple liquid outlet connectors 30 are connected to multiple outlet ports 12. The liquid outlet connectors 30 are connected to the outlet ports 12 and protrude from the outer periphery of the cooling pipe 10. During assembly, the pipes or flow channels of multiple devices that need to be cooled are connected to the outlet ports 12 of the cooling pipe 10 through the liquid outlet connectors 30. The connection with external devices is more stable. In this way, the coolant in the cooling pipe 10 is not easy to loosen during the process of being introduced into the devices, and the overall structural stability is higher.

[0033] Preferably, the liquid outlet connector 30 can be any existing hose connector, rigid pipe connector, or quick-connect connector or other connectors used for connecting pipes. Specifically, it can be welded, glued, or integrally formed on the cooling pipe 10.

[0034] Furthermore, it also includes multiple guide tubes 31, one end of which is connected to and conducts through multiple liquid outlet connectors 30, and the other end of which is connected to the outside.

[0035] During assembly, guide pipes 31 are connected to the liquid outlet connector 30 to allow the coolant in the cooling pipe 10 to be discharged into the guide pipe 31 through the outlet 12. The guide pipe 31 can be attached to the external equipment or inserted into the external equipment. In this way, after the guide liquid is poured into the guide pipe 31, the coolant flowing in the guide pipe 31 can cool and reduce the temperature of the external equipment without the need to open a tank or flow channel in the external equipment, making the assembly simpler.

[0036] In addition, the guide tube 31 can be detachably connected to the liquid outlet connector 30 by insert or connector (such as bolts, screws, etc.), so that the guide tube 31 and the cooling tube 10 can be detached, which is convenient for later maintenance and replacement.

[0037] Preferably, the guide tube 31 can be made of materials with good thermal conductivity and corrosion resistance, such as stainless steel or aluminum alloy.

[0038] Similarly, an inlet connector 20 is provided on the inlet 11. The inlet connector 20 is connected to the flow channel. During assembly, the outlet of the container for holding coolant is connected to the inlet connector 20 through a hose, water pipe or other pipeline. The pipeline is connected and fixed through the inlet connector 20, making the connection more stable. In this way, the coolant is not easy to loosen during the process of being introduced into the flow channel, and the overall structure is more stable.

[0039] Preferably, the liquid inlet connector 20 can be any existing hose connector, rigid pipe connector, or quick-connect connector or other connectors used for connecting pipes. Specifically, it can be welded, glued, or integrally formed on the cooling pipe 10.

[0040] Furthermore, the liquid inlet connector 20 has a first end and a second end. The first end is inserted into the liquid inlet 11 and abuts against the inner wall of the liquid inlet 11. The second end is used to fit onto the outer periphery of the liquid inlet 11 after the first end is inserted into the liquid inlet 11.

[0041] During assembly, the first end of the liquid inlet connector 20 is inserted into the liquid inlet 11 and abuts against the inner wall of the liquid inlet 11, and the second end is fitted onto the outer periphery of the liquid inlet 11 to prevent the coolant in the guide channel from flowing out from the gap between the first end and the inner wall of the liquid inlet 11, thus achieving a better sealing effect.

[0042] Furthermore, a plug 13 is provided at the other end of the cooling pipe 10 away from the liquid inlet connector 20. The plug 13 is used to block the other end of the flow channel away from the liquid inlet 11.

[0043] Specifically, if the sealing head 13 is not set to block the other end of the flow channel, the coolant in the flow channel may be discharged from the other end of the flow channel, resulting in the coolant not being evenly distributed to the multiple outlets 12 and not being able to circulate centrally. Therefore, in this embodiment, the other end of the flow channel is provided with a sealing head 13 to block the other end of the flow channel, so that the coolant can only be discharged from the multiple outlets 12 after entering through the inlet 11, which facilitates centralized circulation and makes the structure more practical.

[0044] More specifically, the sealing head 13 includes a third end and a fourth end. During assembly, the third end is inserted into the guide channel, and the fourth end is fitted onto the outer periphery of the cooling pipe 10 after the third end is inserted into the guide channel. This allows the fourth end to cover the gap between the third end and the inner wall of the guide channel, preventing the coolant in the guide channel from flowing out from the assembly gap between the third end and the guide channel, thus achieving a better sealing effect.

[0045] Preferably, the plugging head 13 can be a plug-type plugging head 13, a two-stage sealing plugging head 13, or a spherical plugging head 13, etc.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
