Technical Field
[0001] This utility model relates to the field of heat dissipation device technology, and in particular to a heat dissipation mounting plate structure. Background Technology
[0002] A linear motor is an electromagnetic device that directly converts electrical energy into linear motion mechanical energy without the need for intermediate conversion mechanisms (such as gears or ball screws). It boasts advantages such as high precision, high speed, high acceleration, and long lifespan, making it widely used in industrial automation, transportation, semiconductor manufacturing, and medical equipment. Linear motors face heat dissipation challenges during high-power and high-temperature operation. Aluminum nitride ceramics, with their high thermal conductivity, low dielectric constant and dielectric loss, reliable electrical insulation, high-temperature resistance, and corrosion resistance, are frequently used as mounting plates for linear motors (primarily for connecting the linear motor to the linear motion platform) and are applied in the field of linear motor heat dissipation.
[0003] However, existing linear motor mounting plates have a small heat dissipation area and low heat dissipation efficiency; moreover, the coolant circulation system is complex in structure and there is a risk of leakage and corrosion of the mounting plate.
[0004] Therefore, there is an urgent need to propose a heat dissipation mounting plate structure to solve the above problems. Utility Model Content

[0009] The heat dissipation pipes are embedded inside the plate body, and a gaseous cooling medium flows through the heat dissipation pipes.
[0010] Multiple first heat sinks are distributed on the side surface of the plate body away from the heat-generating device. The heat generated by the heat-generating device can be dissipated through the plate body, the cooling medium in the heat dissipation pipes, and the first heat sinks.
[0011] As an optional technical solution for the heat dissipation mounting plate structure, the heat dissipation pipeline includes a plurality of first pipelines extending along a first direction and a plurality of second pipelines extending along a second direction.

[0014] As an optional technical solution for the heat dissipation mounting plate structure, the heat dissipation mounting plate structure further includes a positive pressure air source, which can compress and generate the low-temperature and high-pressure cooling medium. The low-temperature and high-pressure cooling medium enters the first pipeline through each of the first pipe joints.

[0020] The beneficial effects of this utility model are:
[0021] The heat dissipation mounting plate structure provided by this utility model includes a plate body, heat dissipation pipes, and multiple first heat dissipation components. The plate body is made of aluminum nitride ceramic material, which has good thermal conductivity. The plate body is attached to the surface of heat-generating equipment such as linear motors to conduct heat dissipation for the heat-generating equipment. The heat dissipation pipes are embedded inside the plate body, and a gaseous cooling medium flows through the heat dissipation pipes. The cooling medium in the heat dissipation pipes can further remove the heat conducted to the plate body. Compared with an external coolant circulation system, the structure is simple, the space occupied by the heat dissipation mounting plate structure is small, and the risks of liquid leakage and corrosion are avoided.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0030] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0031] This embodiment provides a heat dissipation mounting plate structure, which has a large heat dissipation area, high heat dissipation efficiency and simple structure; it can also avoid the risk of liquid leakage and corrosion.
[0032] Specifically, such as Figures 1 to 3 As shown, the heat dissipation mounting plate structure includes a plate body 100, heat dissipation pipes, and multiple first heat dissipation components 310. Exemplarily, the number of first heat dissipation components 310 can be two, three, nine, or ten, etc. The plate body 100 can be attached to the surface of a heat-generating device such as a linear motor, and the plate body 100 is made of aluminum nitride ceramic material. The heat dissipation pipes (shown as dashed lines in the figure) are embedded inside the plate body 100, and a gaseous cooling medium flows through the heat dissipation pipes. The multiple first heat dissipation components 310 are distributed on the side of the plate body 100 facing away from the heat-generating device, and the heat generated by the heat-generating device can be dissipated through the plate body 100, the cooling medium in the heat dissipation pipes, and the first heat dissipation components 310.
[0033] Based on the above design, the plate body 100 is made of aluminum nitride ceramic material, which has good thermal conductivity. The plate body 100 is attached to the surface of heat-generating equipment such as linear motors to conduct heat and dissipate heat from the heat-generating equipment. Heat dissipation pipes are embedded inside the plate body 100, and gaseous cooling medium flows through the heat dissipation pipes. The cooling medium in the heat dissipation pipes can further remove the heat conducted to the plate body 100. Compared with an external coolant circulation system, the structure is simple, the space occupied by the heat dissipation mounting plate structure is small, and the risks of liquid leakage and corrosion are avoided. Multiple first heat dissipation elements 310 are distributed on the surface of the plate body 100, increasing the contact area between the heat dissipation mounting plate structure and the air, which can further remove the remaining heat conducted to the plate body 100, further improving the heat dissipation efficiency. In other words, the heat generated by the heat-generating equipment can not only be dissipated through heat exchange with the air via the plate body 100 and the first heat dissipation elements 310, achieving air cooling with a large heat dissipation surface and high heat dissipation efficiency; it can also be dissipated through heat exchange with the cooling medium via the heat dissipation pipes, increasing the heat dissipation path, and the pipe structure is simple, thus improving the overall heat dissipation efficiency of the heat dissipation mounting plate structure.
[0034] It should be noted that, in this embodiment, the heat dissipation mounting plate structure is used to connect the linear motor and the linear motion platform.
[0035] Furthermore, the heat dissipation pipeline includes multiple first pipes 210 extending along a first direction and multiple second pipes 220 extending along a second direction. The multiple first pipes 210 are evenly distributed at intervals along the second direction, and the multiple second pipes 220 are evenly distributed at intervals along the first direction. Each second pipe 220 is sequentially connected to multiple first pipes 210. The first direction is the length direction of the plate body 100, and the second direction is the width direction of the plate body 100. The first pipes 210 dissipate heat from the plate body 100 along the length direction, and the second pipes 220 dissipate heat from the plate body 100 along the width direction. The cross-connection of the first pipes 210 and the second pipes 220 improves the temperature uniformity of the cooling medium in the first pipes 210 and the second pipes 220, further improving the temperature uniformity of the plate body 100 and making the heat dissipation of the heat-generating device uniform.
[0036] For example, the number of first pipes 210 can be two, three, or four, etc., and the number of second pipes 220 can be two, seven, or ten, etc. In this embodiment, the number of first pipes 210 is two, and the number of second pipes 220 is twelve.
[0037] Optionally, the two ends of the first pipe 210 along the first direction are the inlet and outlet of the cooling medium, respectively. That is, the cooling medium flows from the first pipe 210 into the heat dissipation pipe and simultaneously flows into each of the second pipes 220 along the first pipe 210. In this embodiment, the length dimension of the plate body 100 is larger than the width dimension, and the above arrangement can improve the flowability of the cooling medium.
[0038] It should be noted that, as Figure 2 As shown, the second pipe 220 has plugs 221 at both ends along the width direction of the plate body 100.
[0039] Furthermore, the heat dissipation mounting plate structure also includes multiple first pipe joints 410 and multiple second pipe joints 420. The first pipe joints 410 and the second pipe joints 420 correspond one-to-one with the first pipe 210 and are located at the inlet and outlet of the corresponding first pipe 210, respectively. The first pipe joints 410 and the second pipe joints 420 are provided at the inlet and outlet to facilitate the entry of the cooling medium into the first pipe 210.
[0040] To accelerate the flow rate of the cooling medium in the heat dissipation pipes, the heat dissipation mounting plate structure also includes a positive pressure air source. The positive pressure air source can compress and generate a low-temperature, high-pressure gaseous cooling medium. The low-temperature, high-pressure cooling medium enters the first pipe 210 through each first pipe joint 410, thereby improving the heat exchange rate of the heat dissipation pipes.
[0041] In this embodiment, the heat dissipation mounting plate structure also includes a first multi-port connector 510 and a second multi-port connector 520. The two ends of the first multi-port connector 510 are respectively connected to a positive pressure air source and each first pipe connector 410. One end of the second multi-port connector 520 is connected to each second pipe connector 420, and the other end is connected to the outside.
[0042] Optionally, such as Figure 3 As shown, each first heat sink 310 is directly opposite to the first pipe 210, or directly opposite to the second pipe 220, or directly opposite to the intersection of the first pipe 210 and the second pipe 220. That is, the first heat sink 310 is directly opposite the heat dissipation pipe, so that the first heat sink 310 can directly exchange heat with the heat dissipation pipe, thereby improving heat dissipation efficiency. Furthermore, in order to ensure uniform heat dissipation, multiple first heat sinks 310 are evenly distributed at intervals along the first direction and along the second direction.
[0043] Furthermore, the first heat sink 310 is a first boss protruding from the plate body 100. The boss design has a large surface area and high heat dissipation efficiency. For example, the shape of the first boss can be square, rectangular, or circular, etc.
[0044] The second pipe 220 has multiple first threaded holes 101 on both sides. The multiple first threaded holes 101 on each side are evenly spaced along the second direction. The plate body 100 is connected to the heating device through the first threaded holes 101, which has high connection strength and is simple to connect. The first threaded holes 101 avoid the heat dissipation pipe to avoid the first heat dissipation component 310.
[0045] The heat dissipation mounting plate structure also includes a second heat dissipation component 320, which is located at both ends of the plate body 100 on the side away from the heat-generating device along the first direction, further increasing the contact area between the heat dissipation mounting plate structure and the air.
[0046] Furthermore, the second heat sink 320 is a second boss protruding from the plate body 100. The second boss is provided with a second threaded hole, which can be used to install components. The threaded connection is simple to install. Moreover, the second threaded hole is located on the second boss, which avoids components from blocking the plate body 100 and affecting heat dissipation.
[0047] In this embodiment, the second threaded hole is used to install a linear motion stage.
[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
