[0028] Please refer to Figure 1 , the present utility model provides a heat pipe shaping and necking tooling, including: a heat sink 2, a heat pipe 3, and a connector 4 connected in sequence. The heat pipe 3 abuts against the heat sink 2; in some embodiments, the heat sink 2 is provided with clamping grooves 21 corresponding to the heat pipes 3 one by one, and the clamping grooves 21 are used for clamping and fixing the heat pipes 3. The connector 4 is provided with through holes 41 corresponding to the heat pipes 3 one by one, and the heat pipes 3 pass through the through holes 41 so that the connector 4 is sleeved on the heat pipes 3, and one end of the connector 4 abuts against one end of the heat sink 2.
[0029] In some embodiments, both the heat pipe 3 and the heat sink 2 are 3DVC products.
[0030] In some embodiments, the heat pipes 3 are arranged in an elliptical array.
[0031] It can be understood that for the heat pipe shaping and necking tooling provided by the present utility model, by setting a connecting member and opening through holes corresponding to the heat pipes one by one in the connecting member, during the subsequent tooling shaping process, the through holes can play a role in limiting the heat pipes, making the force on the heat pipes on the heat sink plate uniform (and reducing the gap at the connection between the heat pipes and the heat sink plate), which not only avoids damaging the heat pipes, but also ensures that the heat pipes are perpendicular to the heat sink plate, thus facilitating the subsequent welding process during the tooling shaping process and improving the welding quality. Therefore, the present utility model solves the technical problems that the current manual extrusion method will cause uneven force on the heat pipes on the heat sink plate, which is likely to damage the heat pipes and cannot ensure the perpendicularity between the heat pipes and the heat sink plate.
[0032] In some embodiments, as Figure 1 shown, the heat pipe shaping and necking tooling further includes a base 1 and a pressing cover 5 arranged oppositely; wherein, the base 1, the heat sink plate 2, the heat pipe 3, the connecting member 4, and the pressing cover 5 are connected in sequence. The base 1 is used for clamping and fixing the heat sink plate 2; in one implementation, a first clamping groove 11 is opened at one end of the base 1 close to the heat sink plate 2, and the heat sink plate 2 is clamped into the first clamping groove 11 so that the first clamping groove 11 clamps and fixes the heat sink plate 2. The pressing cover 5 is used for clamping and fixing the connecting member 4; in one implementation, a second clamping groove 51 is opened at one end of the pressing cover 5 close to the connecting member 4, and the connecting member 4 is clamped into the second clamping groove 51 so that the second clamping groove 51 clamps and fixes the connecting member 4.
[0033] In some embodiments, as Figure 1 shown, the end face of the pressing cover 5 far from the connecting member 4 receives pressure from a pressing device (which can be but is not limited to a hydraulic press) to shape the heat pipe 3 and the heat sink plate 2.
[0034] In this embodiment, first, the heat pipe is arranged at the heat sink plate, second, the heat pipe and the heat sink plate are arranged at the base, third, the connecting member is arranged at the heat pipe, then the pressing cover is arranged at the connecting member to obtain the to-be-shaped state of the heat pipe shaping and necking tooling, then the heat pipe shaping and necking tooling in the to-be-shaped state is arranged on the working platform of the hydraulic press, then the pressure parameter of the equipment is adjusted to 30 MPa, then the hydraulic press is started to apply pressure for about 2 seconds to obtain the shaped state of the heat pipe shaping and necking tooling, and finally the pressing cover, the connecting member, and the base are taken out in sequence to obtain the overall heat pipe and heat sink plate with uniform force.
[0035] In some embodiments, as Figure 2 and Figure 3As shown, the connecting member 4 is detachably composed of at least two connecting member parts 42. Each connecting member part 42 is provided with a groove 43, and each through hole 41 is composed of two grooves 43 of adjacent connecting member parts 42. Therefore, after the tooling shaping, each connecting member part can be detached from the heat pipe separately, preventing secondary extrusion or bruising of the heat pipe.
[0036] In an implementation manner of this embodiment, the heat pipe 3 is in clearance fit with the through hole 41.
[0037] In some embodiments, the orifice a of the through hole 41 close to the heat spreader 2 is a tapered or flared shape as shown Figure 2 and is a transition shape that contracts towards the inside of the through hole 41.
[0038] In summary, the present utility model provides a heat pipe shaping and necking tooling, including a heat spreader, a heat pipe, and a connecting member. Among them, the heat pipe abuts against the heat spreader, the connecting member is provided with through holes corresponding to the heat pipes one by one, the connecting member is sleeved on the heat pipe through the heat pipe passing through the through holes, and the connecting member abuts against the heat spreader. By setting the connecting member and providing through holes corresponding to the heat pipes one by one in the connecting member, the through holes can play a role in limiting the heat pipes during the subsequent tooling shaping process, making the force on the heat pipes on the heat spreader uniform (and reducing the gap at the connection between the heat pipe and the heat spreader), avoiding bruising the heat pipes and ensuring that the heat pipes are perpendicular to the heat spreader, which is beneficial to the subsequent welding process during the tooling shaping process and improves the welding quality. Therefore, the present utility model solves the technical problem that the current manual extrusion method will cause uneven force on the heat pipes on the heat spreader, which is likely to bruise the heat pipes and cannot ensure the perpendicularity of the heat pipes to the heat spreader.
