Description

Technical Field

[0001] The utility model relates to the technical field of heat pipe secondary removal, in particular to a heat pipe secondary removal device. Background Art

[0002] Heat pipes are heat transfer components used to dissipate heat from electronic devices. Heat pipes transfer heat efficiently from high-temperature to low-temperature areas by absorbing and evaporating the working fluid in the evaporation section and then condensing and releasing the heat in the condensation section. This characteristic has led to their widespread application in cooling systems for electronic devices in a wide range of fields, including computers, communications equipment, LED lighting, and new energy vehicles.

[0003] However, in the production and processing of heat pipes, especially in the "secondary degassing" process of heat pipes (the "secondary degassing" process of heat pipes, that is, the secondary degassing process of heat pipes, is a process treatment carried out during the heat pipe manufacturing process to further improve the vacuum degree and heat transfer performance of the heat pipe. This process heats the heat pipe to vaporize the internal working fluid and release non-condensable gas, and then discharges the non-condensable gas from the heat pipe through a specific mechanism, thereby improving the vacuum degree and heat transfer efficiency of the heat pipe), existing equipment and processes generally have the problem of low efficiency.

[0004] Traditional methods often use a mode of processing only one heat pipe at a time. This serial processing method is not only time-consuming and increases production costs, but also difficult to meet the needs of large-scale production.

[0005] Furthermore, during the subsequent sealing process, the heat pipe must withstand a certain amount of extrusion force to achieve a seal, and the positioning devices at both ends of the heat pipe are often fixed. This causes the middle of the heat pipe to easily stretch and deform when squeezed, causing the entire heat pipe to bend. This bending of the heat pipe not only affects its heat transfer efficiency but can also adversely affect the overall structure of the electronic device, such as increasing assembly difficulty and reducing device stability.

[0006] In order to solve at least one of the above problems, the present invention provides a heat pipe secondary removal device. Utility Model Content

[0039] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the figures denote identical or similar structures, and thus repeated descriptions thereof will be omitted.

[0040] The words expressing positions and directions described in this utility model are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of this utility model.

[0041] The utility model introduces a heat pipe secondary removal device.

[0042] In order to prevent the heat pipe from bending during the heat removal process and improve the quality of the product, the heat pipe heat removal device of the present invention includes: a heat pipe (1) after the heat removal, a positioning part, a heating part, a sealing part, and a cutting part. Furthermore, in order to increase the efficiency during the heating process, the heat pipe heat removal device may also include: a pressing part. Furthermore, in order to provide a stable support structure for the entire heat removal device, the heat pipe heat removal device may also include: a base.

[0043] A rear heat pipe (1) of the utility model is parallel to the XOY plane.

[0044] A heat pipe (1) includes a working section (11) and a gas collecting section (12). Furthermore, the working section (11) includes a first end and a second end disposed opposite to each other, and a first side and a second side disposed opposite to each other. Specifically, the first end is connected to the gas collecting section (12). Since the longitudinal cross-sectional area of the working section (11) is larger than the longitudinal cross-sectional area of the gas collecting section (12), a limiting table (13) is formed at the connection between the first end and the gas collecting section (12).

[0045] The positioning portion includes a positioning cylinder (21) and a positioning block (22). The positioning cylinder (21) is connected to the positioning block (22) and drives the positioning block (22) to abut against or away from the second end. For example: if the extension direction of a heat pipe (1) is the X-axis direction, the positioning cylinder (21) drives the positioning block (22) to move back and forth along the X-axis direction; if the extension direction of a heat pipe (1) is the Y-axis direction, the positioning cylinder (21) drives the positioning block (22) to move back and forth along the Y-axis direction. It should be noted that a heat pipe (1) is parallel to the XOY plane, and the positioning block (22) can be away from the second end, so that when a heat pipe (1) is extended and deformed during the subsequent sealing process, an avoidance space can be provided to avoid the lengthened heat pipe (1) from being deformed due to unnecessary squeezing of the equipment.

[0046] The heating part of the utility model is arranged on the first side to heat the working section (11). The pressing part is arranged on the second side to cooperate with the heating part to heat the working section (11).

[0047] The heating portion comprises a heating block (31), and a plurality of first receiving grooves (32) adapted to the second end of the working section (11) are provided on the heating block (31), so as to realize simultaneous processing of a plurality of heat pipes (1).

[0048] The pressing part of the utility model includes a pressing cylinder (61) and a pressing block (62). Furthermore, a plurality of second receiving grooves adapted to the second end of the working section (11) are provided on the pressing block (62), and the second receiving grooves are arranged opposite to the first receiving groove (32). The pressing cylinder (61) is connected to the pressing block (62) and drives the pressing block (62) to move back and forth along the Z-axis direction, that is, the pressing cylinder (61) drives the pressing block (62) to connect to or move away from the working section (11). Specifically, when it is necessary to heat the working section (11), the pressing cylinder (61) drives the pressing block (62) to move toward the heating block (31), and enables the working section (11) to be embedded in the corresponding second receiving groove, so as to cooperate with the heating block (31) to press a heat pipe (1) after removal, thereby improving the heating effect on the working section (11). When the working section (11) does not need to be heated, the pressing cylinder (61) drives the pressing block (62) away from the heating block (31), so that the working section (11) is separated from the second receiving groove, so as to avoid the heat pipe (1) being squeezed due to unnecessary external force during the subsequent process, thereby preventing additional deformation.

[0049] In addition, it should be noted that the first receiving groove (32) and the second receiving groove respectively opened on the heating block (31) and the pressing block (62) not only provide stable support for the heat pipe, but also ensure the synchronization and consistency of the heating and pressing operations, thereby improving the heating efficiency and quality.

[0050] The sealing part of the utility model includes a sealing knife, a sealing cylinder (43), and a sealing clamp. Among them, the sealing clamp includes a sealing upper clamp (41) and a sealing lower clamp (42) arranged relatively to each other. Specifically, the sealing lower clamp (42) is arranged below the gas collecting section (12) and abuts against the limiting table (13), the sealing cylinder (43) is connected to the sealing upper clamp (41), and drives the sealing upper clamp (41) to move back and forth along the Z-axis direction, that is, the sealing cylinder (43) drives the sealing clamp to close or open. Furthermore, the sealing lower clamp (42) is provided with a plurality of limiting grooves (44) adapted to the gas collecting section (12), the notches of the limiting grooves (44) abut against the limiting table (13), and the limiting grooves (44) are arranged relatively to the sealing knife. The sealing knife is arranged on the upper sealing fixture (41), and the sealing knife comprises a plurality of teeth, the shape of the teeth being adapted to the shape of the limiting groove (44).

[0051] Before heating the working section (11), if the heat pipe (1) is not neatly arranged or the placement position is inaccurate, the positioning cylinder (21) can be started to drive the positioning block (22) to move along the extension direction of the heat pipe (1) and abut against the first end, so that all the limiting tables (13) of the heat pipe (1) abut against the notch of the corresponding limiting groove (44), so as to achieve accurate positioning of the heat pipe (1), thereby improving the quality of the product. After heating the working section (11) and after the working section (11) is separated from the second receiving groove, the sealing cylinder (43) drives the sealing clamp to close, so that the blade moves toward the corresponding limiting groove (44) and squeezes the corresponding gas collecting section (12), thereby embedding into the limiting groove (44), thereby achieving sealing of the heat pipe (1). It can be seen that the sealing knife adopts a multi-tooth design and is adapted to the shape of the limiting groove (44), making the sealing operation more uniform and thorough, helping to reduce air leakage and cracking problems at the sealing point, and improving the sealing and reliability of the heat pipe.

[0052] The cutting portion of the utility model is arranged on one side of the sealing portion. Specifically, the cutting portion is arranged on the side of the sealing portion facing away from the working section (11).

[0053] The cutting part comprises a head cutter (53), a head cutter cylinder (51) and an expansion block (52). The head cutter cylinder (51) is connected to one side of the expansion block (52), and the other side of the expansion block (52) is connected to the head cutter (53). The head cutter (53) is connected to the sealing knife, so that in the subsequent cutting process, the redundant part of the sealing side of the gas collecting section (12) can be cut as much as possible to improve the quality of the product.

[0054] When in use, the trimming cylinder (51) drives the trimming blade (53) to move back and forth along the Z-axis direction. Specifically, after sealing a heat pipe (1), the sealing cylinder (43) head is kept in place, and the trimming cylinder (51) is started to drive the trimming blade (53) to move toward the gas collecting section (12) and cut off the excess part of the gas collecting section (12). Then, the sealing cylinder (43) and the trimming cylinder (51) are returned to their original positions.

[0055] The base of the utility model comprises: a support column (71), a mounting plate (72), a first crossbeam (73) and a second crossbeam (74). Further, in order to improve the safety of the equipment, multiple support columns (71) can be provided to provide sufficient supporting force.

[0056] The mounting plate (72) is provided with mounting holes for mounting the sealing cylinder (43) and the cutting cylinder (51), and the mounting plate (72) is connected to one end of the support column (71). The cylinder head of the sealing cylinder (43) mounted on the mounting plate (72) is driven to connect the first crossbeam (73), and the sealing upper clamp (41) is arranged on the first crossbeam (73). In addition, the first crossbeam (73) is movably mounted on the support column (71), so that the first crossbeam (73) can only move back and forth along the support column (71), thereby improving the consistency of the product sealing position. Furthermore, the sealing lower clamp (42) is mounted on the second crossbeam (74), and the second crossbeam (74) is connected to the other end of the support column (71). It can be seen that the base not only provides a stable support structure for the entire secondary removal equipment, but also facilitates the installation and debugging of various components, thereby improving the maintainability and scalability of the equipment.

[0057] In summary, the present invention can accurately control the specific position of the heat pipe in the second removal process by setting a positioning part, which not only provides a reliable benchmark for subsequent heating, sealing and cutting operations, but also improves the uniformity and quality of the same batch of products. In addition, the present invention provides a space for avoiding the deformation of the heat pipe when it is extended during the subsequent sealing process by setting the heat pipe to be parallel to the XOY plane and setting a positioning part composed of a positioning cylinder (21) and a positioning block (22), thereby avoiding the additional deformation of the elongated heat pipe due to unnecessary squeezing of the equipment, thereby improving the quality of the product. Further, the sealing knife of the present invention moves back and forth along the Z axis under the drive of the sealing cylinder (43) to achieve precise sealing; the cutting knife (53) moves back and forth along the Z axis under the drive of the cutting cylinder (51) to achieve precise cutting, which can not only ensure the fixed length of the heat pipe, but also reduce the damage of the heat pipe during the cutting process.

[0058] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limiting the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model. All of these changes should fall within the scope of protection of the claims of the present invention.
