Therefore, it should not be construed as a limitation to the embodiments of this application.
[0033] In order to be able to more clearly understand the above-mentioned objects, technical solutions and advantages of this application, the following will combine the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application, and understand in detail how to solve the problems raised in the above-mentioned background technology.
[0034] As Figures 1 to 4 shown, an optical module radiator includes a base 1. The base 1 is provided with at least two heat dissipation groups 2. The heat dissipation group 2 includes a first heat dissipation fin 3 and at least two second heat dissipation fins 4. Among them, the first heat dissipation fin 3 matches the second heat dissipation fin 4, and initially the second heat dissipation fin 4 is clamped with the first heat dissipation fin 3, and at least two second heat dissipation fins 4 are clamped with each other in sequence.
[0035] Specifically, including but not limited to, the base 1 is a heat dissipation substrate, and the heat dissipation substrate is made of a high thermal conductivity material such as aluminum or copper. The base 1 is in direct contact with an optical module (such as an optical module, an LED chip, etc.) to absorb and conduct heat to the radiator. In this embodiment, there are 6 heat dissipation groups 2. Each heat dissipation group 2 is provided with a first heat dissipation fin 3 and multiple second heat dissipation fins 4. The first heat dissipation fin 3 matches one of the second heat dissipation fins 4, and the two are clamped with each other. The remaining second heat dissipation fins 4 are clamped with each other in sequence to realize the fixed assembly of the first heat dissipation fin 3 and the multiple second heat dissipation fins 4. It should be noted that the first heat dissipation fin 3 and the multiple second heat dissipation fins 4 are both in contact and fit with the base 1, which can increase the contact area and thus improve the heat dissipation efficiency. When installing, the first heat dissipation fin 3 and the second heat dissipation fin 4 can be clamped first, and then the remaining second heat dissipation fins 4 can be clamped with each other to obtain a complete heat dissipation group 2, and then the entire heat dissipation group 2 can be fixed to the base 1 by means of screw fixation. The screw fixation method can open through holes with threads up and down on the base 1, the first heat dissipation fin 3 and the second heat dissipation fin 4. It should be noted that after installation, the first heat dissipation fin 3 and the second heat dissipation fin 4 are both in contact and fit with the base 1 to ensure the heat dissipation effect and efficiency. At the same time, the number of the second heat dissipation fins 4 can be set according to actual needs.
[0036] Through the above solution, the installation efficiency of the radiator is effectively improved, and the convenience of overall disassembly and assembly of the optical module radiator is ensured.
[0037] As Figure 1As shown, as a specific implementation of the improvement, there are a first gap 21 and a second gap 22 between two adjacent heat dissipation groups 2, and the first gap 21 and the second gap 22 are perpendicular to each other, so that multiple heat dissipation groups 2 are distributed vertically and horizontally.
[0038] Specifically, including but not limited to, 6 heat dissipation groups 2 in this embodiment are arranged in 2 horizontal rows and 3 vertical columns, so that there are a first gap 21 and a second gap 22 between two adjacent heat dissipation groups 2. In this embodiment, the length direction and the width direction of the base 1 are the horizontal direction and the vertical direction respectively. Thus, the first gap 21 is between the vertically distributed heat dissipation groups 2, and the second gap 22 is between the horizontally distributed heat dissipation groups 2, thereby providing an air circulation channel and improving the heat dissipation efficiency and effect. Of course, those skilled in the art can adaptively adjust the values of the first gap 21 and the second gap 22 according to actual needs, and no specific limitation is made here.
[0039] As Figure 1 and Figure 3 As shown, as a specific implementation of the improvement, the first heat dissipation fin 3 includes a first fixing portion 34 and two first bending portions 35 symmetrically distributed at both ends of the first fixing portion 34, and the first bending portion 35 abuts against the second heat dissipation fin 4.
[0040] Specifically, including but not limited to, the first heat dissipation fin 3 is an overall rectangular structure, the first fixing portion 34 is a rectangular block at the center, the first bending portion 35 is an extension block bent in the same direction at the upper and lower ends of the first fixing portion 34, the first turning portion is integrally bent along the length of the first fixing portion 34, and the first fixing portion 34 and the first bending portion 35 are integrally formed. At this time, the first bending portion 35 of the first heat dissipation fin 3 abuts against the second heat dissipation fin, thus ensuring the structural stability of the heat dissipation group 2.
[0041] As Figure 1 and Figure 4 As shown, as a specific implementation of the improvement, the second heat dissipation fin 4 includes a second fixing portion 44 and two second bending portions 45 symmetrically distributed at both ends of the second fixing portion 44, and the first bending portion 35 and the second bending portion 45 are arranged facing each other and abut against each other.
[0042] Specifically, including but not limited to, the second heat dissipation fin 4 as a whole is a rectangular structure, the second fixing part 44 is a rectangular block at the center, the second bending part 45 is an extension block bent in the same direction at the upper and lower ends of the second fixing part 44, and the first turning part is integrally bent along the length of the second fixing part 44. The second fixing part 44 and the second bending part 45 are integrally formed. At this time, the second bending part 45 of the second heat dissipation fin 4 abuts against the second heat dissipation fin, thereby ensuring the structural stability of the heat dissipation group 2. Based on this, the overall length of the first heat dissipation fin 3 after bending is less than the overall length of the second heat dissipation fin 4 after bending, and the lengths of the first bending part 35 and the second bending part 45 are the same, which can make the two fit closely. When installing, the first heat dissipation fin 3 is embedded in the second heat dissipation fin 4, and the first bending part 35 and the second bending part 45 at the upper and lower ends abut. It should be noted that the bending directions of the first bending part 35 and the second bending part 45 are opposite, and they are clamped towards each other during installation.
[0043] As Figures 2 to 4 shown, as a specific implementation of the improvement, at least one first notch 351 is provided on the first bending part 35, at least one second notch 451 is provided on the second bending part 45, and at least one clamping block 341 is provided on the first fixing part 34 or the second fixing part 44. The clamping block 341 is arranged at the first notch 351 or the second notch 451.
[0044] Specifically, including but not limited to, the first notch 351 and the second notch 451 are respectively arranged along the first bending part 35 and the second bending part 45, and the first entrance penetrates through the whole first bending part 35 and extends to the first fixing part 34. The numbers of the first notch 351 and the second notch 451 are the same. The clamping block 341 is a rectangular block, and the thickness of the clamping block 341 is the same as that of the first fixing part 34 or the second fixing part 44. The clamping block 341 is arranged at the first notch 351 or the second notch 451, and the clamping block 341 is fixedly connected to the first fixing part 34 or the second fixing part 44. The clamping block 341 is perpendicular to the first bending part 35 or the second bending part 45. Based on this, during installation, the clamping block 341 of the first heat dissipation fin 3 is embedded in the second bending part 45, and multiple second heat dissipation fins 4 are clamped in sequence. The clamping block 341 of the previous second heat dissipation fin 4 is embedded in the second bending part 45 of the next second heat dissipation fin 4, and so on, which can realize the clamping and fixing of the first heat dissipation fin 3 and multiple second heat dissipation fins 4, improve the structural stability and firmness, and increase the heat dissipation area.
[0045] As Figure 4 shown, as a specific implementation of the improvement, at least one convex part 452 is further provided on the second bending part 45. The convex part 452 is provided with a bayonet 453, the bayonet 453 is communicated with the second notch 451, the convex part 452 corresponds to the first notch 351 or the second notch 451, and the bayonet 453 corresponds to the clamping block 341.
[0046] Specifically, including but not limited to, the convex portion 452 is disposed at the second notch 451, and the convex portion 452 extends along the second bending portion 45. A bayonet 453 is provided in the convex portion 452, and the bayonet 453 corresponds to the latch 341. At this time, the bayonet 453 is in communication with the second notch 451. Based on this, when the first heat dissipation fin 3 and the second heat dissipation fin 4 are installed, the bayonet 453 of the first heat dissipation fin 3 is inserted into the bayonet 453 of the convex portion 452. When two adjacent second heat dissipation fins 4 are installed, the convex portion 452 of the latter second heat dissipation fin 4 is inserted into the second notch 451 of the previous second heat dissipation fin 4, and the bayonet 453 of the previous second heat dissipation fin 4 is inserted into the bayonet 453 of the latter second heat dissipation fin 4, which can ensure that a plurality of second heat dissipation fins 4 can be clamped tightly.
[0047] Such as Figure 1 and Figure 2 As shown in the figure, as a specific implementation of the improvement, a rib 342 is provided on one side surface of the first fixing portion 34, and a groove 441 is provided on one side surface of the second fixing portion 44.
[0048] Specifically, including but not limited to, a rectangular rib 342 is provided on one side surface of the first fixing portion 34 of the first heat dissipation fin 3. Correspondingly, a rectangular depression is formed on the other side surface of the first fixing portion 34, and the rib 342 and the depression correspond to each other. A rectangular groove 441 is provided on one side surface of the second fixing portion 44 of the second heat dissipation fin 4. Correspondingly, a rectangular protrusion is formed on the other side surface of the second fixing portion 44, and the groove 441 and the protrusion correspond to each other. This can increase the structural strength and the heat dissipation area. Of course, those skilled in the art can set the number and shape of the rib 342 and the groove 441 according to actual needs, and no specific limitation is made here.
[0049] Such as Figure 1 As shown in the figure, as a specific implementation of the improvement, a third gap 5 is provided between the first heat dissipation fin 3 and the second heat dissipation fin 4 or between two adjacent second heat dissipation fins 4.
[0050] Specifically, including but not limited to, after the first heat dissipation fin 3 and the second heat dissipation fin 4, or a plurality of second heat dissipation fins 4 are installed, due to the formation of the first turning portion and the second bending portion 45, the third gap 5 is generated. The third gap 5 can be changed by setting the dimensions of the first turning portion and the second bending portion 45. The setting of the third gap 5 can improve the air circulation, thereby improving the heat dissipation efficiency and effect.
[0051] Such as Figures 1 to 4As shown, as a specific implementation of the improvement, the first heat dissipation fin 3 includes a first fin 31, a second fin 32, and a third fin 33. Correspondingly, the second heat dissipation fin 4 includes a fourth fin 41, a fifth fin 42, and a sixth fin 43. The first fin 31 corresponds to the fourth fin 41, the second fin 32 corresponds to the fifth fin 42, and the third fin 33 corresponds to the sixth fin 43.
[0052] Specifically, including but not limited to, in this implementation, the first bending portion 35 at one end of the first fin 31 and the second bending portion 45 at one end of the fourth fin 41 both have a first notch 351. The first bending portion 35 at one end of the second fin 32 and the second bending portion 45 at one end of the fifth fin 42 both have two first notches 351. The first bending portion 35 at one end of the third fin 33 and the second bending portion 45 at one end of the sixth fin 43 both have three first notches 351. During assembly, the first fin 31 is snap-connected to multiple fifth fins 42, the second fin 32 is snap-connected to multiple fifth fins 42, and the third fin 33 is snap-connected to multiple sixth fins 43, thereby forming three different heat dissipation groups 2. Each heat dissipation group 2 can be provided with multiple ones, so that multiple heat dissipation groups 2 with the same or different structures can be matched with each other. Finally, only multiple heat dissipation groups 2 need to be fixed to the base 1 to improve the convenience of overall disassembly and assembly. Of course, in some other implementations, the first heat dissipation fin 3 and the second heat dissipation fin 4 can also be set as fins with various different structures according to requirements, but it is necessary to ensure that the corresponding first heat dissipation fin 3 and the second heat dissipation fin 4 can be matched, and those skilled in the art can also freely match multiple heat dissipation groups 2 to ensure the diversity and heat dissipation effect of the radiator.
[0053] Finally, it should be noted that the above are only the preferred implementation manners of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
