Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, and specifically to a multi-segment powder adding device for heat pipes. Background Technology

[0002] Heat dissipation technology is widely used in electronic devices. Traditional computers, mobile phones, servers and other internal chips generate a lot of heat during operation. If the heat is not dissipated in time, it will affect the chip's operating performance or even damage the chip.

[0003] Existing heat dissipation components are generally metal heat pipes. Typically, copper powder is added inside the copper pipe and sintered to form a capillary structure. After refrigerant is injected, the pipe is vacuum-sealed. A trace amount of refrigerant or pure water will remain in the capillary. The heat dissipation effect is greatly improved through the principle of water gas-liquid conversion and reflux.

[0004] Currently, during the manufacturing process of heat dissipation components, copper powder needs to be added inside the copper pipes. To improve the efficiency of powder addition, powder filling machines have emerged on the market to achieve automatic powder dispensing, such as the powder filling machine disclosed in existing technology CN202111321865.4. However, this method has the following problems:

[0005] 1. Although it can fill two different metal powders, it simply adds one or more feeding mechanisms, resulting in a complex structure and large equipment size;

[0006] 2. The height of the feeding mechanism cannot be adjusted, and it can only fill powder for a specific length of passage, which limits its applicability. Utility Model Content

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] Appendix Figure 1-2 The heat pipe multi-segment powder feeding device of this utility model includes a frame 1, a powder feeding mechanism 2, and a height adjustment mechanism 3 installed on the frame 1 for adjusting the height of the powder feeding mechanism 2.

[0030] The powder dispensing mechanism 2 includes a powder dispensing support 21, a long strip hollow section 22 disposed on the powder dispensing support 21, guide rail assemblies 23 disposed on both sides of the long strip hollow section 22, a movable seat 24 slidably disposed on the guide rail assembly 23, and a linear module 25 disposed on the powder dispensing support 21 for driving the movable seat 24 to translate; the movable seat 24 is provided with at least two powder dispensing units 26 placed along the translation direction and located in the long strip hollow section 22.

[0031] During operation: The three powder feeding units 26 respectively store three different sizes of copper powder, such as 5um, 10um and 20um; During powder feeding: The linear module 25 drives the movable seat 24 to move along the guide rail assembly 23, so that the corresponding powder feeding unit 26 feeds the powder to the vibrating powder filling mechanism, making the structure simpler and more compact and reducing the overall volume.

[0032] Furthermore, such as Figure 3As shown, the powder dispensing unit 26 includes a quantitative powder dispensing module 261, a transfer powder hopper 262 located on top of the quantitative powder dispensing module 261, and a mixing tank 263 located on top of the transfer powder hopper 262; the mixing tanks 263 of the multiple powder dispensing units 26 are interconnected and driven by a stirring motor 27.

[0033] During operation: copper powder is manually placed in the mixing tank 263; when the copper powder in the intermediate powder hopper 262 is insufficient, the mixing tank 263 will automatically replenish the intermediate powder hopper 262; the intermediate powder hopper 262 will dispense powder through the quantitative powder dispensing module 261, and finally inject the copper powder into the vibrating powder filling mechanism in a quantitative manner through the quantitative powder dispensing module 261; since smaller copper powder particles will settle at the bottom of the mixing tank 263 during the static process, the mixing tank 263 will be driven to rotate by the mixing motor 27 before each replenishment of the intermediate powder hopper 262 to ensure that the copper powder in the mixing tank 263 is evenly mixed.

[0034] Furthermore, such as Figure 4 As shown, the powder feeding unit 26 also includes an elastic frame 264 disposed at the bottom of the quantitative powder feeding module 261 and a vibration motor 265 disposed on the elastic frame 264; the feeding hopper 2611 at the outlet of the quantitative powder feeding module 261 is mounted on the elastic frame 264; when the quantitative powder feeding module 261 feeds powder through the feeding hopper 2611, since the feeding hopper 2611 is mounted on the elastic frame 264, the vibration motor 265 can drive the elastic frame 264 to vibrate the feeding hopper 2611, preventing copper powder from remaining on the inner wall of the feeding hopper 2611.

[0035] Furthermore, such as Figure 4 As shown, the elastic frame 264 includes guide rods vertically arranged at the bottom of the quantitative powder dispensing module 261, a horizontally placed floating seat 2641 with both ends slidably arranged on the guide rail, springs 2642 respectively sleeved on the guide rods and located between the quantitative powder dispensing module 261 and the floating seat 2641, and limiting blocks 2643 respectively arranged at the lower end of the guide rods to prevent the floating seat 2641 from detaching from the guide rods; the feeding hopper 2611 and the vibration motor 265 are both mounted on the floating seat 2641;

[0036] During operation: The vibration motor 265 drives the floating seat 2641 to vibrate the feeding hopper 2611. The spring 2642 increases the vibration effect, while the guide rod acts as a limit, so that the feeding hopper 2611 can only vibrate up and down, avoiding misalignment between the feeding hopper 2611 and the discharge port of the quantitative powder dispensing module 261.

[0037] Furthermore, such as Figure 3 As shown, the top of the mixing tank 263 is provided with a powder inlet and a sealing cap 2631; the bottom of the mixing tank 263 is provided with a powder outlet switch.

[0038] Furthermore, such as Figure 3As shown, the side of the mixing tank 263 is provided with an observation window 2632 to facilitate observation of the remaining amount of copper powder inside the mixing tank 263.

[0039] Furthermore, such as Figure 3 As shown, a sensor 2621 is provided on the side of the transfer powder hopper 262. The sensor 2621 is used to detect the remaining amount of copper powder in the transfer powder hopper 262. When the remaining amount of copper powder in the transfer powder hopper 262 is less than a preset value, the mixing tank 263 will automatically replenish the transfer powder hopper 262.

[0040] Furthermore, such as Figure 1 As shown, the frame 1 includes multiple vertically placed guide columns 11 and a top plate 12 horizontally arranged on top of the multiple guide columns 11; the powder feeding bracket 21 is sleeved on the four guide columns 11.

[0041] The height adjustment mechanism 3 includes two screws 31 that are vertically and rotatably mounted on the top plate 12, nuts 32 that are mounted at both ends of the powder lowering bracket 21 and connected to the screws 31, and a belt drive 33 mounted on the top plate 12 for simultaneously driving the two screws 31 to rotate.

[0042] During operation: Since the nuts 32 at both ends of the powder feeding bracket 21 are threadedly connected to the two screws 31 respectively, the two screws 31 are driven to rotate simultaneously through the belt drive 33, which can drive the powder feeding bracket 21 to perform lifting and lowering movements, thereby achieving height adjustment.

[0043] Furthermore, such as Figure 1 As shown, each of the guide posts 11 has a connecting seat 13 at its bottom, which facilitates installation onto existing equipment.

[0044] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
