Description

Technical Field

[0001] This utility model belongs to the field of motor technology, and relates to a linear motor, and more particularly to a linear motor cooling mechanism. Background Technology

[0002] A linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without requiring any intermediate conversion mechanism.

[0003] A cooling device is an important component of a linear motor. Its structure is illustrated in a novel linear motor cooling device disclosed in the Chinese Patent Database (application number: 201810858094.4). This novel linear motor cooling device includes a stator unit and a mover unit. The mover unit is slidably mounted on the stator unit. The mover unit includes a coil, an iron core structure, several trapezoidal blocks, and a cooling structure. The iron core structure includes several iron core laminations. The trapezoidal blocks are parallel to the gaps between the iron core laminations. The coil is wound around the iron core laminations. The cooling structure includes a transition block and several water pipes. The transition block is located outside the mover unit and has an inlet, an outlet, and several transition block water channels. The inlet, the transition block water channels, the water pipes, and the outlet are interconnected. The water pipes are arranged around the mover unit and are close to the coil. The water pipes are made of copper.

[0004] In actual products, the moving unit also needs to be placed in a mold and encapsulated with epoxy resin. Since most of each water pipe is suspended, the epoxy encapsulation process can easily cause adjacent water pipes to bend and fold together, creating localized hot spots and affecting heat dissipation. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a linear motor cooling mechanism with a stable structure and good heat dissipation.

[0006] The objective of this utility model can be achieved through the following technical solution: A linear motor cooling mechanism, wherein the linear motor includes an elongated iron core assembly, the cooling mechanism includes a support base and multiple water guide pipes arranged vertically side by side, the support base is located on one side of the iron core assembly, and an inlet channel and an outlet channel are formed inside the support base, and the number of outlets of the inlet channel and the number of inlets of the outlet channel are the same as the number of water guide pipes, the water guide pipes are rectangular ring structures and are horizontally sleeved on the outside of the iron core assembly, one side of the water guide pipe is open, and both ends of each water guide pipe are respectively connected to the outlet of the corresponding inlet channel and the inlet of the outlet channel, characterized in that the gap between two adjacent water guide pipes is 0.3cm to 0.7cm, a ring of support members is provided between two adjacent water guide pipes, and multiple support members in the same ring are distributed at intervals around the central axis of the water guide pipe, and the upper and lower sides of the support members are respectively pressed and fixed on the two adjacent water guide pipes.

[0007] A ring of support is installed between two adjacent water pipes to stably separate them and form a gap, preventing the accumulation of hot spots between the two adjacent water pipes from affecting heat dissipation, thus ensuring the structural stability and heat dissipation effect of this cooling mechanism.

[0008] In the aforementioned linear motor cooling mechanism, the support component includes a column and two positioning sleeves respectively formed at both ends of the column. The shape and size of the positioning sleeves match the outer wall of the water guide pipe, and the two positioning sleeves on the same support component are respectively fitted onto the corresponding two water guide pipes. The positioning sleeves and water guide pipes cooperate to form a pre-positioning, which not only enhances the support and limiting effect on the water guide pipe, but also facilitates subsequent positioning and assembly.

[0009] In the aforementioned linear motor cooling mechanism, the water guide pipe consists of two long sides and two short sides, with the opening located on one of the short sides. At least two of the aforementioned support members are provided between each pair of adjacent long sides, and at least one of the aforementioned support members is provided on each of the other two adjacent short sides. This design ensures a reasonable distribution of support members, making the cooling mechanism more stable.

[0010] In the aforementioned linear motor cooling mechanism, the support component is an integral structure.

[0011] In the linear motor cooling mechanism described above, the positioning sleeve and the corresponding water guide pipe are fixed together by adhesive bonding.

[0012] As an alternative, in the aforementioned linear motor cooling mechanism, the positioning sleeve and the corresponding water guide pipe are fixed together by welding.

[0013] In the aforementioned linear motor cooling mechanism, the two ends of the water guide pipe are respectively embedded in the outlet of the corresponding water inlet channel and the inlet of the water outlet channel.

[0014] Compared with existing technologies, this linear motor cooling mechanism has the following advantages: 1. A ring of support is installed between two adjacent water pipes to stably separate them and form a gap, so as to avoid the accumulation of local hot spots in the two adjacent water pipes and affect heat dissipation, thus ensuring the structural stability and heat dissipation effect of this cooling mechanism.

[0015] 2. The positioning sleeve and the water guide pipe work together to form a pre-positioning, which not only enhances the support and limiting effect of the water guide pipe, but also facilitates subsequent positioning and assembly. Attached Figure Description

Detailed Implementation

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] Example 1: In this linear motor cooling mechanism, the linear motor includes an elongated iron core assembly 1. The iron core assembly 1 includes a silicon steel sheet assembly and a coil disposed on the silicon steel sheet assembly. This structure is a conventional structure and will not be described in detail here.

[0022] The linear motor cooling mechanism includes a support base 2 and multiple water pipes 3 arranged vertically side by side.

[0023] in, The support base 2 is located on one side of the iron core assembly 1. The support base 2 has a water inlet channel 2a and a water outlet channel 2b formed inside it. The water inlet channel 2a includes one inlet and multiple outlets, and the number of outlets is the same as the number of water guide pipes 3. The water outlet channel 2b includes one outlet and multiple inlets, and the number of inlets is the same as the number of water guide pipes 3.

[0024] The water guide pipe 3 has a rectangular ring structure and is horizontally sleeved on the outside of the iron core assembly 1. One side of the water guide pipe 3 is open, and both ends of each water guide pipe 3 are respectively connected to the outlet of the corresponding water inlet channel 2a and the inlet of the water outlet channel 2b. In this embodiment, the shape and size of both ends of the water guide pipe 3 are matched with the outlet of the water inlet channel 2a and the inlet of the water outlet channel 2b, respectively, and both ends of the water guide pipe 3 are respectively embedded in the outlet of the corresponding water inlet channel 2a and the inlet of the corresponding water outlet channel 2b, so as to simplify the structure and facilitate assembly.

[0025] In the actual product, both the water pipe 3 and the support base 2 are made of brass to ensure a better seal between them. Of course, it is also possible to use heat-conducting materials such as stainless steel or aluminum alloy for the water pipe 3 and the support base 2.

[0026] like Figure 1 and Figure 2 As shown, the gap between two adjacent water pipes 3 is 0.3cm to 0.7cm, and preferably 0.6cm. A ring of support members 4 is provided between each pair of adjacent water pipes 3. Multiple support members 4 in the same ring are distributed at intervals around the central axis of the water pipe 3, and the upper and lower sides of the support members 4 are respectively pressed and fixed to the two adjacent water pipes 3.

[0027] A ring of support members 4 is set between two adjacent water pipes 3 to stably separate the two adjacent water pipes 3 and form a gap, so as to avoid the accumulation of local hot spots in the two adjacent water pipes 3 and affect heat dissipation, thus ensuring the structural stability and heat dissipation effect of this cooling mechanism.

[0028] In this embodiment, as Figure 2 and Figure 3 As shown, the support member 4 is an integral structure, including a column 4a and two positioning sleeves 4b respectively formed at both ends of the column 4a, and the two positioning sleeves 4b are symmetrically arranged along the center of the column 4a. The shape and size of the positioning sleeves 4b match the outer wall of the water guide pipe 3, and the two positioning sleeves 4b on the same support member 4 are respectively fitted onto the corresponding two water guide pipes 3. The positioning sleeves 4b and the water guide pipes 3 cooperate to form a pre-positioning, which not only enhances the support and limiting effect on the water guide pipes 3, but also facilitates subsequent positioning and assembly.

[0029] The preferred cross-section of the water guide pipe 3 is annular, and the cross-section of the positioning sleeve 4b is arc-shaped, so as to increase the contact area between the water guide pipe 3 and the positioning sleeve 4b, and enable the support member 4 to better support and limit the water guide pipe 3.

[0030] Support component 4 is made of metal materials such as aluminum alloy or stainless steel to provide better support. Of course, it is also possible to make support component 4 out of plastic.

[0031] To further explain, the water guide pipe 3 consists of two long sides 3a and two short sides 3b, with the aforementioned opening located on one of the short sides 3b; at least two of the aforementioned support members 4 are provided between each pair of adjacent long sides 3a, and at least one of the aforementioned support members 4 is provided on each of the other two adjacent short sides 3b. This design ensures a reasonable distribution of the support members 4, making the cooling mechanism's structure more stable.

[0032] In the actual product, the positioning sleeve 4b is fixed to the corresponding water guide pipe 3 by adhesive bonding. There are three water guide pipes 3; three of the above-mentioned support members 4 are provided between each pair of adjacent long sides 3a; and one of the above-mentioned support members 4 is provided between each pair of adjacent short sides 3b.

[0033] Example 2: The structure and principle of Example 2 are basically the same as those of Example 1. The difference is that the positioning sleeve 4b and the corresponding water pipe 3 are fixed together by welding.

[0034] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
