Description

Technical Field

[0001] The invention relates to cooling technology, and in particular to a linear motor cooling module. Background Art

[0002] Linear motors usually generate a lot of heat when running, so they need cooling to maintain a proper operating temperature. The common system uses coolant to flow through the heat dissipation part of the motor, absorb the heat, and then take the heat away from the motor to keep the motor temperature within an acceptable range.

[0003] However, the coolant usually flows too smoothly in the flow channel, so the temperature is higher in the part close to the motor and lower in the part far from the motor, resulting in uneven temperature distribution, which in turn affects the cooling effect.

[0004] To this end, the Japanese patent application JP2021164193A discloses that a plurality of protrusions are arranged in the flow channel to divide the coolant into multiple streams, while the protrusions disclosed in the Japanese patent application JP2004260941A are wing-shaped and located at the turning position of the flow channel to guide the flow direction of the coolant. However, the flow states of the coolants disclosed in these cases did not cause significant turbulence, and the problem of uneven temperature distribution still exists. Summary of the invention

[0102] Please refer to Figures 1 to 9As shown, a linear motor cooling module of the first embodiment of the present invention is used to be assembled on a linear motor (not shown) for heat dissipation and cooling. The linear motor cooling module includes a main body (10), a flow channel (20), an inlet (30), an outlet (40) and a plurality of spoiler components (50).

[0103] The main body (10) comprises a first plate portion (11) and a second plate portion (12), and a first end surface (111) of the first plate portion (11) and a second end surface (121) of the second plate portion (12) are overlapped with each other along the direction of a virtual first axis (Z).

[0104] The flow channel (20) is defined by grooves relatively recessed in the first end surface (111) and the second end surface (121), and can extend arbitrarily in the body (10). Figure 1 As shown, different sections of the flow channel (20) extend along a virtual second axis (Y) or a third axis (X), respectively, and the second axis (Y) and the third axis (X) are respectively perpendicular to the first axis (Z), and the second axis (Y) and the third axis (X) are respectively parallel to the plane formed by the first end surface (111) or the second end surface (121). The inlet (30) is provided on the first plate portion (11) and connects a starting end (21) of the flow channel (20) with the outside of the body (10). The outlet (40) is provided on the first plate portion (11) and connects an end (22) of the flow channel (20) with the outside of the body (10), and a cooling fluid is provided to flow therein by connecting the inlet (30), the flow channel (20) and the outlet (40).

[0105] However, for the sake of convenience, the following only describes the flow channel (20). Figure 1 In the portion of the dotted line frame, the flow channel (20) has a predetermined length (L) on the second axis (Y), a predetermined width (W) on the third axis (X), and a predetermined height (T) on the first axis (Z).

[0106] The spoiler component (50) is located in the flow channel (20) and satisfies the condition that the length (L) of the flow channel (20) is greater than or equal to the width (W) of the flow channel (20). The spoiler component (50) has a first protrusion (51) and a second protrusion (52). The first protrusion (51) is protrudingly disposed on the first end surface (111) and extends toward the second end surface (121) along the direction of the first axis (Z) to have a first height (t f), and a first flow guide space (512) is formed between the extension end (511) of the first protrusion (51) and the second end surface (121), the second protrusion (52) and the first protrusion (51) are partially staggered and protruded on the second end surface (121) along the positive projection of the first axis (Z) on the second end surface (121), and extend along the direction of the first axis (Z) toward the first end surface (111) to have a second height (t r ), and a second flow guiding space (522) is formed between the extended end (521) of the second protrusion (52) and the first end surface (111), and the first height (t f ) and the second height (t r ) is less than or equal to the height (T) of the flow channel (20). Fig. 6A and Figure 6B As shown, the distance (G) between the extension end (511) of the first protrusion (51) and the extension end (521) of the second protrusion (52) on the first axis (Z), the first height (t f ), the second height (t r ) and the height (T) of the flow channel (20) satisfy the following formula (1):

[0107] G=T-(t f +t r ), and G can be 0. (1)

[0108] In addition, if the first height (t f ), the second height (t r ) is too small, which may result in a low processing yield and make it difficult to maintain the integrity of the spoiler component (50). For this reason, experiments are conducted with or without the spoiler component (50) and with the spoiler component (50) having a spacing (G) of 0 and a spacing (G) of not 0. The experimental results are as follows: Fig.16 To this end, the first height (t f ), the second height (t r ) and the height (T) of the flow channel (20) satisfy the following formula (2):

[0109] tf≧0.2*T, tr≧0.2*T, And α is between 0.4 and 1. (2)

[0110] The aforementioned misalignment means that the positional relationship between the first protrusion (51) and the second protrusion (52) may be, but is not limited to, staggered, interlaced, etc. Figure 3 , Figure 4 and Fig. 9In this example, the first protrusion (51) and the second protrusion (52) are symmetrically arranged in outline shape, and respectively include a first end (513, 523), a connecting portion (514, 524), a second end (515, 525), a first guide plane (516, 526) and a second guide plane (517, 527), the connecting portion (514, 524) bridges between the first end (513, 523) and the second end (515, 525), and the connecting portion (514, 524) has two opposite end sides in the extension direction. The first guide plane (516, 526) and the second guide plane (517, 527) are configured such that the forward projections of the second guide plane (517) of the first protrusion (51) and the second guide plane (527) of the second protrusion (52) on the second end surface (121) along the first axis (Z) are opposite to each other, while the forward projections of the first guide plane (516) of the first protrusion (51) and the first guide plane (526) of the second protrusion (52) on the second end surface (121) along the first axis (Z) are opposite to each other, such as Fig. 9 As shown, each of the first guide planes (516, 526) extends with a first radius of curvature, and each of the second guide planes (517, 527) extends with a second radius of curvature.

[0111] Furthermore, the first end (513) of the first protrusion (51) and the first end (523) of the second protrusion (52) are respectively in a first circular structure on a cross section of the second axis (Y), and their forward projections on the second end surface (121) along the first axis (Z) overlap each other, and the first circular structures have the same radius (Rt). Fig.10 According to the experimental results, when the ratio of the radius (Rt) to the width (W) of the flow channel (20) is greater than 18%, the temperature rises significantly and the heat dissipation effect is compromised. Moreover, if the radius (Rt) is too small, it will lead to processing difficulties and a decrease in yield.

[0112] Accordingly, the radius (Rt) and the width (W) of the flow channel (20) satisfy the following formula (3):

[0113] Rt / W ≤ 18%, and Rt ≥ 0.5 mm. (3)

[0114] According to Fig.11 According to the experimental results, when the distance (Wt) between the geometric center of the overlapping portion between the first protrusion (51) and the second protrusion (52) and the center line (O) of the flow channel (20) parallel to the second axis (Y) is greater than or equal to 15% of the width (W) of the flow channel (20), the temperature increases significantly. Accordingly, the distance (Wt) and the width (W) of the flow channel (20) satisfy the following formula (4):

[0115] 0% ≦ Wt / W ≦ 15%; (4)

[0116] In other words, the location of the spoiler component (50) is moved from the center line (O) of the flow channel (20) toward the first end surface (111) or the second end surface (121) by the distance (Wt), that is, calculated as W / 2±Wt.

[0117] The second end (515) of the first protrusion (51) and the second end (525) of the second protrusion (52) are respectively in a second circular structure on the cross section of the second axis (Y), and the second circular structures have the same radius (Rh), and the forward projection of the second end (515) of the first protrusion (51) on the second end surface (121) and the second end (525) of the second protrusion (52) are staggered. Fig.12 According to the experimental results, the higher the ratio between the distance (K) between the second end (515) of the first protrusion (51) and the imaginary line (F) extending along the second axis (Y) from the geometric center of the overlapping portion between the first protrusion (51) and the second protrusion (52), and the minimum distance (E) between the first end (513) and the second end (515) of the first protrusion (51) along the second axis (Y), the better the heat dissipation effect. However, due to the limitation of the specific size, the distance (K) and the distance (E) satisfy the following formula (5):

[0118] E / K≧1. (5)

[0119] In addition, according to equations (3) and (5), the dimensional variation limits of various values, in particular, the radius (Rt), the width (W) of the flow channel (20), the first radius of curvature, the second radius of curvature, and the radius (Rh) can be combined to obtain a plurality of spoiler components (50) of different shapes, such as Fig.17 The examples of the first protrusion (51) include several variations, but are not limited thereto. The first curvature radius has a limiting range of 1.25Rt≦first curvature radius≦60Rt, and the second curvature radius has a limiting range that is the same as the first curvature radius, or is slightly adjusted.

[0120] like Figure 8 As shown, there is a first angle (β1) between the line connecting the first end (513) of the first protrusion (51) and the second end (515) of the first protrusion (51) and the imaginary line (F) extending along the second axis (Y) from the geometric center of the overlapping portion between the first protrusion (51) and the second protrusion (52). Taking the first angle (β1) as an example, a test is conducted, wherein β1=45° is the control group, and other different angles are the experimental groups. The experimental results are shown in FIG. Fig.13When β1≦35°, the temperature rises; when the angle β≧65°, the temperature is also higher than the control group. Therefore, the first angle (β1) is defined as being between 35° and 65°.

[0121] Furthermore, there is a second angle (β2) between the line connecting the first end (523) of the second protrusion (52) and the second end (525) of the second protrusion (52) and the imaginary line (F) extending along the second axis (Y) from the geometric center of the overlapping portion between the first protrusion (51) and the second protrusion (52), and similarly, the second angle (β2) is between 35° and 65°.

[0122] In addition, according to Fig.14 According to the experimental results, the more spoiler components (50) are arranged in the flow channel (20), the better the heat dissipation effect. Fig.15 According to the experimental results, when the ratio between the distance (P) between any two adjacent spoiler components (50) along the second axis (Y) and the width (W) of the flow channel (20) is ≧1, the temperature begins to decrease; and when P / W ≧2, the temperature begins to increase. Furthermore, if the distance (P) is too large, the total number of spoiler components (50) may be reduced, thereby affecting the spoiler effect. The distance (P) and the width (W) of the flow channel (20) satisfy the following formula (6):

[0123] 1≦P / W≦2. (6)

[0124] Based on the above structural description, the specific usage of the present invention is as follows.

[0125] First, if Figure 1A As shown, when the external cooling fluid flows through the overlapping portion of the first protrusion (51) and the second protrusion (52), it is obstructed and diverted, forming a first lateral spoiler (P1) and a second lateral spoiler (P2) in the direction of the second axis (Y) and the third axis (X).

[0126] Then, a portion of the first transverse spoiler (P1) separates from the second transverse spoiler (P2) along the first guide plane (516) of the first protrusion (51); and another portion of the first transverse spoiler (P1) flows into the first guide space (512) along the contour shape of the extension end (511) of the first protrusion (51) and changes the distribution position of the external cooling fluid in the flow channel (20) on the first axis (Z), so as to form a first longitudinal spoiler (H1) in the direction of the first axis (Z), such as Figure 5A As shown;

[0127] A portion of the second transverse spoiler (P2) is separated from the first transverse spoiler (P1) along the first guide plane (526) of the second protrusion (52); and another portion of the second transverse spoiler (P2) is flowed into the second guide space (522) along the contour shape of the extension end (521) of the second protrusion (52) and changes the distribution position of the external cooling fluid in the flow channel (20) on the first axis (Z), so as to form a second longitudinal spoiler (H2) in the direction of the first axis (Z), such as Figure 5B shown.

[0128] Fig.18 This is the second embodiment of the present invention, which differs from the first embodiment in that the forward projection of the first circular structure of the first protrusion (51A) on the second end surface (121A) partially overlaps with the first circular structure of the second protrusion (52A). In other words, the forward projection of the first circular structure of the first protrusion (51A) on the second end surface (121A) along the first axis (Z) is tangent to the first circular structure of the second protrusion (52A), and the distance (Wg) between the centers of curvature of the first circular structures and the radius (Rt) of the first circular structure satisfy the following formula (7):

[0129] Wg≦2*Rt-1, and Wg is not 0. (7)

[0130] Furthermore, the distance (Y) between the second end (515A) of the first protrusion (51A) and the second end (525A) of the second protrusion (52A), the width (W) of the flow channel (20A), the radius (Rt) of the first circular structure, and the distance (Wg) between the centers of curvature of the first circular structures satisfy the following formula (8):

[0131] 2*Rt+Wg≦Y≦W. (8)

[0132] The difference between the third embodiment of the present invention and the first embodiment is that the shape of the spoiler component is changed, such as Fig.19 Taking the first protrusion (51B) as an example, the second end (515B) of the first protrusion (51B) is a rectangular structure in the cross section of the second axis (Y), and the second guide plane (517B) extends along a straight line, while the first guide plane (516B) still extends in an arc. The shape design of the second protrusion is the same as that of the first protrusion (51B), so it is not repeated here.
