Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, and specifically to a temporary powder storage mechanism for adding powder to 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 tubes. 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 and another powder filling machine disclosed in existing technology CN202310488117.8. However, the feeding mechanism can only inject powder into two copper tubes at a time, while the vibrating powder filling mechanism is equipped with dozens of copper tubes, resulting in a long powder injection waiting time and greatly reducing work efficiency. Utility Model Content

[0008] Preferably, the powder dispensing switch includes a box body, a cavity disposed within the box body, a first through hole that vertically passes through the box body and corresponds to the powder storage cup and hopper respectively, a powder dispensing block that is horizontally slidably disposed within the cavity, a second through hole that is vertically disposed on the powder dispensing block, a spring that is horizontally disposed within the cavity to drive the powder dispensing block to misalign and prevent the first through hole and the second through hole from communicating, and a powder dispensing cylinder that is horizontally disposed outside the box body to drive the powder dispensing block to align and communicate the first through hole and the second through hole.

[0009] Preferably, the hopper has a gradually decreasing diameter from top to bottom, and the lower end of the hopper is placed at an angle to the outside, while the outlet has a flat structure.

[0010] Preferably, the temporary powder storage module further includes several striking electromagnets disposed on the top of the temporary powder storage turntable and located on one side of the temporary powder storage cup.

[0011] Preferably, the lifting assembly includes multiple vertically placed guide rods, a top plate horizontally arranged on top of the multiple guide rods, a lifting plate sleeved on the multiple guide rods, and a drive module arranged on the top plate for driving the lifting plate to rise and fall.

[0012] The rotating mechanism is located at the bottom of the lifting plate and adopts a hollow rotating platform;

[0013] The drive module includes a motor vertically mounted on the top plate, a lead screw vertically passing through the hollow rotating platform and connected to the motor, and a nut mounted on the lifting plate and connected to the lead screw.

[0014] Preferably, each of the guide rods has a connecting seat at its bottom.

[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] This invention allows copper powder to be stored in a temporary powder cup in advance during the installation of copper tubes, powder cups, or vibrating fillers in existing vibrating powder filling mechanisms.

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] Appendix Figure 1-2 The temporary powder storage mechanism for adding powder to a heat pipe according to this utility model includes a temporary powder storage module 1, a rotating mechanism 2 for driving the temporary powder storage module 1 to rotate, and a lifting component 3 for driving the rotating mechanism 2 to rise and fall.

[0025] The temporary powder storage module 1 includes a temporary powder storage turntable 11, a plurality of hoppers 12 disposed at the bottom of the temporary powder storage turntable 11, a plurality of temporary powder storage cups 13 disposed at the top of the temporary powder storage turntable 11 and corresponding to the positions of the hoppers 12, and a plurality of powder dispensing switches 14 disposed on the temporary powder storage turntable 11 and located between the temporary powder storage cups 13 and the hoppers 12.

[0026] During operation: The temporary powder storage mechanism is located directly above the existing vibrating powder filling mechanism. The rotating mechanism 2 drives the temporary powder storage mechanism to make intermittent movements. The existing powder feeding mechanism injects copper powder into the temporary powder storage cup 13 one by one in advance. After the vibrating powder filling mechanism is filled manually and all the powder cups are installed on the copper tubes, the outlets of several hoppers 12 are aligned with the powder cups on several copper tubes. At this time, the powder discharge switch 14 opens the channel, allowing the copper powder stored in several temporary powder storage cups 13 to flow into the powder cups through the corresponding hoppers 12, and then into the gap between the copper tubes and the core rod, saving a lot of powder filling waiting time and greatly improving work efficiency.

[0027] Furthermore, such as Figure 3-4 As shown, the powder dispensing switch 14 includes a box body 141, a cavity 142 disposed in the box body 141, a first through hole 143 that vertically passes through the box body 141 and corresponds to the temporary powder cup 13 and the hopper 12 respectively, a powder dispensing block 144 that is horizontally slidably disposed in the cavity 142, a second through hole 145 that is vertically disposed on the powder dispensing block 144, a spring 146 that is horizontally disposed in the cavity 142 to drive the powder dispensing block 144 to misalign and prevent the first through hole 143 and the second through hole 145 from communicating, and a powder dispensing cylinder 147 that is horizontally disposed outside the box body 141 to drive the powder dispensing block 144 to align and communicate the first through hole 143 and the second through hole 145.

[0028] When the existing vibrating powder filling mechanism is not fully filled with copper pipes or when all copper pipes are not properly installed with powder cups, the powder discharge cylinder 147 does not work. Driven by the spring 146, the powder discharge block 144 causes the first through hole 143 and the second through hole 145 to be misaligned and disconnected, resulting in the copper powder stored in the temporary powder cup 13 being unable to flow into the powder cup. When the vibrating powder filling mechanism is manually filled and all powder cups are properly installed on the copper pipes, the powder discharge cylinder 147 drives the powder discharge block 144 to align and connect the first through hole 143 and the second through hole. The copper powder stored in several temporary powder cups 13 flows into the powder cup through the corresponding hopper 12, realizing the switching function.

[0029] Furthermore, such as Figure 3 As shown, the hopper 12 has a gradually smaller aperture from top to bottom, and the lower end of the hopper 12 is placed at an angle to the outside. At the same time, the outlet has a flat structure, which makes it easy for copper powder to flow into the powder cup and avoids copper powder from spilling out of the powder cup, thus affecting the heat dissipation effect of the copper tube.

[0030] Furthermore, such as Figure 3 As shown, the temporary powder module 1 also includes several striking electromagnets 15 disposed on the top of the temporary powder turntable 11 and located on one side of the temporary powder cup 13; during operation, the striking electromagnets 15 strike the temporary powder cup 13, which not only allows the copper powder stored in the temporary powder cup 13 to flow into the powder cup quickly, but also prevents copper powder from remaining on the inner wall of the temporary powder cup 13.

[0031] Furthermore, such as Figure 1-2 As shown, the lifting assembly 3 includes multiple vertically placed guide rods 31, a top plate 32 horizontally arranged on top of the multiple guide rods 31, a lifting plate 33 sleeved on the multiple guide rods 31, and a drive module arranged on the top plate 32 for driving the lifting plate 33 to rise and fall.

[0032] The rotating mechanism 2 is located at the bottom of the lifting plate 33 and adopts a hollow rotating platform;

[0033] The drive module includes a motor 34 vertically mounted on the top plate 32, a lead screw 35 vertically passing through the hollow rotating platform and connected to the motor 34, and a nut 36 mounted on the lifting plate 33 and connected to the lead screw 35.

[0034] During operation: the hollow rotating platform can drive the temporary powder turntable 11 to make intermittent movements; since the lead screw 35 is threadedly connected to the nut 36 on the lifting plate 33, when the motor 34 drives the lead screw 35 to rotate, the lifting plate 33 can move up and down along the four guide rods 31; the rotating mechanism 2 adopts a hollow rotating platform, and the lead screw 35 passes vertically through the hollow rotating platform, which not only avoids interference, but also makes the overall mechanism more compact.

[0035] Furthermore, such as Figure 1 As shown, each of the guide rods 31 has a connecting seat 37 at its bottom, which facilitates installation onto existing equipment.

[0036] Furthermore, such as Figure 2-3 As shown, several upper positioning modules 4 for fixing the upper end of the copper tube are set at the bottom periphery of the temporary powder turntable 11; the hopper 12 is located next to the upper positioning module 4. After the upper positioning module 4 fixes the upper end of the copper tube, the hopper 12 is aligned with the powder cup on the copper tube, so that the copper powder in the hopper 12 can flow accurately into the powder cup.

[0037] 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.
