Description

Technical Field

[0001] This application relates to the field of friction disk heat dissipation technology, and in particular to a friction disk heat dissipation device. Background Technology

[0002] In the electroplating zinc bath process, the cathode roller conducts current through a copper friction disc, while the carbon brush acts as a conductive medium, directly contacting the copper friction disc to ensure smooth current transfer to the electroplating solution and complete the zinc plating process. However, this design faces a series of challenges in practical applications.

[0003] First, when the current during the electroplating process reaches a certain peak value, the contact resistance between the carbon brush and the copper friction disk generates a large amount of heat. This heat not only causes a significant increase in the temperature of the copper friction disk but also poses a potential threat to surrounding electrical components such as cables. Due to copper's good thermal conductivity, this heat quickly diffuses throughout the entire copper friction disk, causing its temperature to rise further.

[0004] Secondly, the high temperature of the copper friction disc not only accelerates the aging process of cables and reduces their service life, but may also directly cause the insulation layer of the cables to burn, leading to serious safety accidents such as short circuits or fires. Furthermore, since the electroplating tank is usually filled with corrosive electroplating solutions, the high temperature may also exacerbate the corrosion of electrical components such as cables, further increasing safety hazards.

[0005] In summary, how to prevent the copper friction disc from overheating and avoid the resulting safety hazards such as cable burnout and spontaneous combustion has become a pressing technical problem to be solved in the current electroplating and zinc plating process. Utility Model Content

[0006] The purpose of this application is to provide a friction disk heat dissipation device to solve the problem in the prior art where the heat between the carbon brush and the copper friction disk causes the copper friction disk to overheat, leading to potential safety hazards.

[0007] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0008] On one hand, this application provides a friction disk heat dissipation device, comprising:

[0009] A friction disk having a heat dissipation cavity inside, with a cathode roller connected inside the heat dissipation cavity;

[0010] A carbon brush holder is located on the outside of the friction disc and has multiple fixing chambers on it;

[0011] Carbon brushes, multiple carbon brushes are disposed in each fixed chamber and slide in contact with the friction disc;

[0012] A heat sink is disposed on one side of the friction disk and has a heat dissipation channel inside that communicates with the heat dissipation cavity.

[0013] A heat dissipation cavity is incorporated within the friction disc to effectively disperse heat, preventing overheating at the contact point between the friction disc and the carbon brush. The carbon brush holder is located on the outside of the friction disc and features a mounting chamber for securing the carbon brushes, ensuring stable sliding contact between the brushes and the friction disc during electroplating and facilitating current conduction. Multiple carbon brushes prevent localized overheating caused by a single brush contacting the friction disc. A heat sink is located on one side of the friction disc and contains heat dissipation channels connected to the heat dissipation cavity. These channels effectively dissipate heat from the cavity to the external environment. The heat sink is made of a highly thermally conductive metal, such as aluminum or copper.

[0014] Optionally, the carbon brush chamber contains a compression spring, which axially presses and fixes the carbon brush. The compression spring ensures that the carbon brush maintains contact with the friction disc throughout the electroplating process.

[0015] Optionally, the friction disc is provided with multiple air holes, which are connected to the heat dissipation cavity and do not intersect with the contact surface of the carbon brush. During the electroplating process, the cathode roller drives the friction disc, and the air holes are designed to utilize external airflow or airflow generated by a fan to carry away heat from the heat dissipation cavity, further improving heat dissipation efficiency.

[0016] Optionally, the heat sink includes a heat-conducting part and a heat-dissipating part;

[0017] The heat-conducting part is located inside the heat dissipation cavity and is in contact with the inner wall of the heat dissipation cavity. The heat-conducting part is provided with an air inlet that communicates with the air hole.

[0018] The heat dissipation part is connected to the heat conduction part and is located outside the heat dissipation cavity.

[0019] In this design, the heat-conducting part is located inside the heat dissipation cavity, closely fitting the inner wall to ensure rapid heat transfer from the friction disc to the heat sink. An air inlet connected to the vent is designed on the heat-conducting part, allowing external air or fan-generated airflow to smoothly enter the heat dissipation cavity and exchange heat with the heat-conducting part. The heat dissipation part is located outside the heat dissipation cavity. Its purpose is to maximize the heat dissipation area and improve heat dissipation efficiency.

[0020] During the electroplating process, the heat generated by the friction disc is first absorbed by the heat-conducting part inside the heat dissipation chamber. Because the heat-conducting part is tightly fitted to the inner wall of the heat dissipation chamber, heat can be rapidly transferred to it. Simultaneously, the friction disc rotates under the drive of the cathode roller, allowing external air to quickly enter the heat dissipation chamber through the vents and carrying away the air inside. Furthermore, as heat is transferred, since the heat dissipation part is located outside the heat dissipation chamber and in direct contact with the external air, the heat in the heat sink can also be quickly dissipated into the external environment. This not only improves heat dissipation efficiency but also makes the heat dissipation process more uniform and stable.

[0021] Optionally, the heat dissipation section has multiple heat dissipation fins. These fins increase the contact area with the outside air, thereby accelerating heat dissipation.

[0022] Optionally, the air vents are arc-shaped, and multiple air vents are equidistantly arranged around the sidewall of the friction disc. The arc shape of the air vents allows for more effective guidance of external air into the heat dissipation chamber. During the electroplating process, the friction disc rotates along with the cathode roller. As the friction disc rotates, external air can more easily enter the heat dissipation chamber through the arc-shaped air vents, exchanging heat with the heat sink and thus improving heat dissipation efficiency. The equidistant arrangement of multiple air vents around the sidewall of the friction disc ensures uniform heat transfer and dissipation. This layout not only improves heat dissipation efficiency but also makes the heat dissipation process more stable, avoiding localized overheating.

[0023] Compared with the prior art, the beneficial effects achieved by this application are as follows:

[0024] First, this application incorporates a heat dissipation cavity inside the friction disc, effectively dispersing the heat generated by the friction disc into the cavity, thereby significantly increasing the heat dissipation area of ​​the friction disc. This ensures the stability and safety of the electroplating process. Furthermore, the uniformity of heat dissipation is enhanced by incorporating multiple carbon brushes. The multiple carbon brushes result in a more even heat distribution on the surface of the friction disc, avoiding localized overheating caused by concentrated heat, thus extending the service life of the friction disc and improving the overall stability of the electroplating process.

[0025] Secondly, this application cleverly incorporates air vents on the friction disc, allowing external air to be introduced into the heat dissipation chamber during its rotation, significantly accelerating the airflow within the chamber. This airflow not only facilitates rapid heat dissipation but also removes heat from the chamber, further enhancing heat dissipation efficiency.

[0026] Furthermore, the heat-conducting part can quickly absorb heat from the friction disc and efficiently transfer it to the heat dissipation part through close contact with the heat dissipation cavity. The heat dissipation part has multiple heat dissipation fins, which increases the heat dissipation area and enables the heat to be quickly dissipated into the external environment, thereby achieving effective heat transfer and dissipation.

Detailed Implementation

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0032] Example 1

[0033] This embodiment describes a heat dissipation device for a friction disk 1, referencing... Figure 1 The heat dissipation device for the friction disk 1 in this embodiment includes: a friction disk 1, which is a copper friction disk 1 in this embodiment. The friction disk 1 has a heat dissipation cavity 11, and during the electroplating zinc process, the cathode roller 2 is connected to the heat dissipation cavity 11. A carbon brush holder 3 is disposed on the outside of the friction disk 1, and has multiple fixing chambers 31 on it. Multiple carbon brushes 4 are disposed in each fixing chamber 31 and slide in contact with the friction disk 1. By setting multiple carbon brushes 4, local overheating caused by contact between a single carbon brush 4 and the friction disk 1 is avoided, thereby extending the service life of the friction disk and improving the overall stability of the electroplating process. A heat sink 5 is disposed on one side of the friction disk 1 and has a heat dissipation channel 51 communicating with the heat dissipation cavity 11.

[0034] In this embodiment, a heat dissipation cavity 11 is provided inside the friction disk 1, allowing heat to be effectively dispersed within the friction disk 1 and preventing overheating at the contact point between the outer side of the friction disk 1 and the carbon brush 4. A carbon brush holder 3 is located on the outer side of the friction disk 1 and has a fixing chamber 31 designed on it. The fixing chamber 31 is used to install and fix the carbon brush 4, ensuring that the carbon brush 4 can stably slide in contact with the friction disk 1 during electroplating, thus achieving current conduction. A heat sink 5 is located on one side of the friction disk 1, and its interior is designed with a heat dissipation channel 51 connected to the heat dissipation cavity 11. The heat dissipation channel 51 is used to conduct heat from the heat dissipation cavity 11 to the external environment, achieving effective heat dissipation. The heat sink 5 is made of a metal material with high thermal conductivity, such as aluminum or copper. During the electroplating process, when current is conducted to the friction disk 1 through the carbon brush 4, a certain amount of heat energy is generated. This heat energy is effectively dispersed into the heat dissipation cavity 11 through friction, thereby significantly increasing the heat dissipation area of ​​the friction disk 1. This ensures the stability and safety of the electroplating process.

[0035] In this embodiment, a compression spring 6 is provided inside the carbon brush 4 chamber, which axially presses and fixes the carbon brush 4. The compression spring 6 ensures that the carbon brush 4 maintains contact with the friction disk 1 during the electroplating process.

[0036] Example 2:

[0037] Based on the same inventive concept as Embodiment 1, refer to Figure 1 The difference between this embodiment and Embodiment 1 is that in this embodiment, the friction disk 1 is provided with multiple air holes 12, which are connected to the heat dissipation cavity 11, and the contact surfaces of the air holes 12 and the carbon brush 4 do not intersect. During the electroplating process, the cathode roller 2 drives the friction disk 1, and the air holes 12 are designed to utilize the airflow generated by external air flow or a fan to carry away the heat in the heat dissipation cavity 11, thereby further improving the heat dissipation efficiency.

[0038] Furthermore, the heat sink 5 includes a heat-conducting part 52 and a heat-dissipating part 53. The heat-conducting part 52 is located inside the heat dissipation cavity 11 and is in contact with the inner wall of the heat dissipation cavity 11. The heat-conducting part 52 is provided with an air inlet 521 that communicates with the air hole 12. The heat-dissipating part 53 is connected to the heat-conducting part 52 and is located outside the heat dissipation cavity 11.

[0039] In this design, the heat-conducting part 52 is located inside the heat dissipation cavity 11 and is tightly fitted to the inner wall of the heat dissipation cavity 11, ensuring that heat can be quickly transferred from the friction disk 1 to the heat sink 5. An air inlet 521 connected to the air vent 12 is designed on the heat-conducting part 52, allowing external air or airflow generated by a fan to smoothly enter the heat dissipation cavity 11 through the air vent 12 and exchange heat with the heat-conducting part 52. The heat dissipation part 53 is located outside the heat dissipation cavity 11. The purpose of the heat dissipation part 53 is to maximize the heat dissipation area and improve heat dissipation efficiency.

[0040] During the electroplating process, the heat generated by the friction disc 1 is first absorbed by the heat-conducting part 52 inside the heat dissipation cavity 11. Because the heat-conducting part 52 is tightly fitted to the inner wall of the heat dissipation cavity 11, heat can be rapidly transferred to it. Simultaneously, the friction disc 1 rotates under the drive of the cathode roller 2, allowing external air to quickly enter the heat dissipation cavity 11 through the air vents 12, carrying away the air inside the cavity. Furthermore, as heat is transferred, since the heat dissipation part 53 is located outside the heat dissipation cavity 11 and is in direct contact with the external air, the heat in the heat sink 5 can also be quickly dissipated into the external environment. This not only improves heat dissipation efficiency but also makes the heat dissipation process more uniform and stable.

[0041] Furthermore, the heat dissipation section 53 has multiple heat dissipation fins 531. The multiple heat dissipation fins 531 increase the contact area with the outside air, thereby accelerating heat dissipation.

[0042] In this embodiment, the air vents 12 are arc-shaped, and multiple air vents 12 are equidistantly arranged around the side wall of the friction disk 1. The arc shape of the air vents 12 can more effectively guide external air into the heat dissipation cavity 11. During the electroplating process, as the cathode roller 2 rotates, the friction disk 1 also rotates. When the friction disk 1 rotates, external air can more smoothly enter the heat dissipation cavity 11 through the arc-shaped holes and exchange heat with the heat sink 5, thereby improving heat dissipation efficiency. The multiple air vents 12 are equidistantly arranged around the side wall of the friction disk 1, ensuring uniform heat transfer and dissipation. This layout not only improves heat dissipation efficiency but also makes the heat dissipation process more stable, avoiding local overheating.

[0043] The above description is only a preferred embodiment of this application. 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 this disclosure / application, and these improvements and modifications should also be considered within the protection scope of this disclosure / application.
