Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of radiator design, in particular to a luminous radiator. Background Art
[0002] As the power consumption of electronic products increases, the demand for radiators is also increasing. Taking home computers as an example, the computer host needs to install a radiator to carry out targeted heat dissipation treatment on highly integrated modules such as motherboards and graphics cards to ensure the smooth operation of the equipment. After meeting basic functional requirements, in order to further enhance product competitiveness, computer hosts have now entered an era of personalized design. For radiators, radiators in the past only needed to provide cooling functions, but most of today's radiators have introduced lighting functions, which can emit light according to preset states.
[0003] In traditional heat sinks, the light module is usually integrated on the fan and then attached to the outside of the heat sink body (for example, an ARGB fan obtained by integrating an LED light board into a fan). The defects of this traditional design are: the light emitting area is concentrated on the installation side of the light module (i.e. the side where the fan is located), the light effect presented is close to a plane, and the uniformity and three-dimensional effect of the light effect are poor. Utility Model Content
[0004] Based on this, the utility model provides a luminous heat sink, which utilizes an embedded design to integrate a light-emitting module into a heat sink body, thereby obtaining a three-dimensional light-emitting effect from the inside out, thereby achieving the purpose of improving the uniformity and three-dimensional effect of the light effect.
[0005] A luminous heat sink, comprising:

Moreover, the setting of the shading portion prevents the light of the first light board and the second light board from being directly emitted to the outside, and avoids the situation of high local light intensity, so that the uniformity of the overall light emission is better. Through the above-mentioned design, the light-emitting module is integrated into the heat sink body by using an embedded design, and a three-dimensional light-emitting effect from the inside to the outside is obtained, so as to achieve the purpose of improving the uniformity and three-dimensional sense of the light effect.

[0040] Embodiment 1
[0041] like Figures 1 to 7 As shown, it is a luminous heat sink 100 according to an embodiment of the present invention.
[0042] like Figure 1 and Figure 2 As shown, the light-emitting heat sink 100 includes: a heat sink body 10, a light-emitting module 20 embedded in the heat sink body 10, and a top cover 30 installed on the heat sink body 10. The heat sink body 10 is used to connect an object that needs heat dissipation (such as a CPU, a graphics card, etc.) to achieve a rapid heat dissipation effect. The light-emitting module 20 is used to provide a light source and form a light effect with good uniformity and three-dimensional sense on the heat sink body 10. The top cover 30 is used to fix the light-emitting module 20 on the heat sink body 10 and protect the light-emitting module 20.
[0043] Below, combined Figures 1 to 7 , the above-mentioned light emitting heat sink 100 is further explained.
[0044] Combination Figure 2 , Figure 4 ,as well as Figure 6 As shown, the heat sink body 10 includes: a fin group 11 and a heat pipe 12 passing through the fin group 11. The fin group 11 is provided with a plurality of heat dissipation fins 111 arranged in sequence along the extension direction of the heat pipe 12. The fin group 11 is provided with a clamping hole 112, a first receiving groove 113, and a second receiving groove 114 arranged parallel to the heat pipe 12. The clamping hole 112, the first receiving groove 113, and the second receiving groove 114 all extend inward from one end of the fin group 11. Figure 4 As shown, the first receiving groove 113 is located on one side of the fin group 11, and the second receiving groove 114 is located on the other side of the fin group 11 and is symmetrical to the first receiving groove 113. The two sides of the fin group 11 are respectively provided with a light shielding portion 115 and a light leakage groove 116 parallel to the heat pipe 12.
[0045] Combination Figure 4 and Figure 6 As shown, in this embodiment, the first receiving groove 113 and the second receiving groove 114 are both blind grooves, that is, at the other end of the fin group 11 (corresponding to Figure 4 The last heat dissipation fin 111 at the bottom of the fin group 11) is not provided with holes corresponding to the first receiving groove 113 and the second receiving groove 114. The purpose of its provision is to support the light-emitting module 20 (that is, it can support the bottom of the first light board 21 and the second light board 22 mentioned below).
[0046] Combination Figure 2 , Figure 4 ,as well as Figure 5 As shown, the light emitting module 20 includes: a first light board 21, a second light board 22, and a power line 23 connected in series with the first light board 21 and the second light board 22. Figure 3 As shown, the first lamp board 21 is inserted into the first receiving groove 113, and the second lamp board 22 is inserted into the second receiving groove 114, and the first lamp board 21 and the second lamp board 22 are respectively opposite to the light shielding portion 115. Figure 4 As shown, the power line 23 extends from one end of the fin group 11 where the entrance end of the clamping hole 112 is located along the outer side of the fin group 11 to the other end of the fin group 11. It should be noted that in this embodiment, the power line 23 of the light-emitting module 20 is not only used to connect the power supply, but also used to connect the control board of the device to realize the control of the light-emitting state of the first light board 21 and the second light board 22.
[0047] Considering that the power line 23 needs to be routed outside the fin group 11, in order to facilitate the wiring, Figure 4 As shown, in this embodiment, a limiting groove 117 for accommodating the power cord 23 is provided on the outer side of the fin group 11. The limiting groove 117 is a blind groove connected to the outside of the fin group 11. The limiting groove 117 can limit the routing of the power cord 23 to facilitate cable management, and the blind groove is provided so that the power cord 23 can be extended to the outside according to actual installation requirements to connect to the power supply or the control board of the device.
[0048] In this solution, there are many specific installation methods for the light emitting module 20. According to different installation methods, the structural arrangement of the light emitting module 20 will be different. Figure 4 and Figure 5 As shown, in this embodiment, the power line 23 is provided with a first branch line 231 and a second branch line 232. The first branch line 231 and the second branch line 232 are both clamped between the top cover 30 and the fin group 11. The first branch line 231 is connected to the first light board 21, and the second branch line 232 is connected to the second light board 22. The power line 23 is partially fixed by clamping the first branch line 231 and the second branch line 232, thereby indirectly fixing the first light board 21 and the second light board 22. The use of branch lines to achieve fixation and routing is low in cost and easy to implement, but the disadvantage is that the routing is complicated and the difficulty of wiring is high.
[0049] like Figure 3 and Figure 5 As shown, in this embodiment, the first light board 21 and the second light board 22 are each provided with a plurality of LED lights that are sequentially spaced and distributed along the extension direction of the heat pipe 12. The plurality of LED lights that are sequentially spaced and distributed along the extension direction of the heat pipe 12 are more likely to achieve a variety of three-dimensional lighting effects. It is additionally noted that the control method for the LED light board is a common control method, and in this solution, it does not involve improvements to the control method for the light emission of the LED lamp.
[0050] like Figure 1 and Figure 2 As shown, the top cover 30 is located at one end of the fin set 11 where the entrance end of the snap-in hole 112 is located. Figure 5 As shown, the top cover 30 is provided with a buckle portion 31, a first limiting portion 32, and a second limiting portion 33. Figure 3 As shown, the buckle portion 31 is connected to the buckle hole 112. The first limiting portion 32 abuts against the outer side of the first lamp board 21 to force the first lamp board 21 to be close to the fin group 11, and the second limiting portion 33 abuts against the outer side of the second lamp board 22 to force the second lamp board 22 to be close to the fin group 11. Figure 3 For example, the top cover 30 applies an inward extrusion force to the first lamp board 21 and the second lamp board 22 , so that the first lamp board 21 is closely attached to the inner side of the first receiving groove 113 , and the second lamp board 22 is closely attached to the inner side of the second receiving groove 114 .
[0051] To improve the convenience of installation, Figure 3 and Figure 5 As shown, in this embodiment, the buckle portion 31 is a convex column with a locking tooth. The convex column with a locking tooth can be engaged with the heat dissipation fin 111 without screws, which is easy to operate.
[0052] Brief description of working principle:
[0053] like Figure 3As shown, the light-emitting module 20 is integrated into the heat sink body 10 in an embedded manner, and the top cover 30 is used to fix and protect the light-emitting module 20. The light-emitting module 20 is provided with a first light board 21 and a second light board 22 respectively located on opposite sides of the fin group 11. The first light board 21 and the second light board 22 are arranged along the extension direction of the heat pipe 12, and a light shielding portion 115 is provided on the fin group 11 to face the first light board 21 and the second light board 22. Therefore, when the first light board 21 and the second light board 22 start to emit light, on the plane where the heat dissipation fins 111 are located, the light is emitted from the gaps between the heat dissipation fins 111 and the light leakage grooves 116 to form a single-layer effect of emitting light from the inside to the outside, and along the direction of the heat pipe 12, a multi-layer three-dimensional light-emitting effect is exhibited. Moreover, the provision of the light shielding portion 115 prevents the light of the first light board 21 and the second light board 22 from being directly projected to the outside, avoids the situation where the local light intensity is large, and makes the overall light uniformity better.
[0054] The above-mentioned light emitting heat sink 100 utilizes an embedded design so that the light emitting module 20 is integrated into the heat sink body 10, thereby obtaining a three-dimensional light emitting effect from the inside out, thereby achieving the purpose of improving the uniformity and three-dimensional effect of the light effect.
[0055] It is additionally noted that the light emitting heat sink 100 may further include a fan. The fan may be mounted on the heat sink body 10, i.e., located on the outer side of the fin group 11. As a preferred configuration, the fan may be placed close to the side where the power line 23 of the fin group 11 is routed, so that the bus of the fan and the power line 23 of the light emitting module 20 may be routed together, making it more convenient to manage the cables.
[0056] Embodiment 2
[0057] like Figures 8 to 12 As shown, it is a luminous heat sink 100 according to another embodiment of the present invention.
[0058] The difference between this embodiment and the first embodiment is that: Figures 8 to 11 As shown, in this embodiment, the light-emitting module 20 further includes: a PCB board 24 that connects the first light board 21 and the second light board 22 in series. The power line 23 is connected in series with the first light board 21 and the second light board 22 via the PCB board 24. The PCB board 24 is clamped between the top cover 30 and the fin group 11. The power line 23 is connected in series with the first light board 21 and the second light board 22 by means of the PCB board 24, which reduces the amount of wiring and reduces the difficulty of wiring.
[0059] In order to improve the positioning accuracy and reliability of the light emitting module 20, Figure 8 As shown, in this embodiment, the fin set 11 is further provided with a positioning hole 118. Fig.12 As shown, the top cover 30 is also provided with a positioning portion 34 inserted into the positioning hole 118. Figures 8 to 11 As shown, the PCB board 24 is provided with a position avoidance hole 241 for the positioning portion 34 to pass through. Fig. 9 As shown, the positioning portion 34 passes through the PCB board 24 and forces the PCB board 24 to be pressed against the fin group 11. The positioning portion 34 is used to position the PCB board 24, and the first limiting portion 32 and the second limiting portion 33 can be used to limit the first lamp board 21 and the second lamp board 22 more accurately and stably.
[0060] Furthermore, in this embodiment, the top cover 30 may be a transparent cover, and the PCB board 24 is snapped onto the inner side of the top cover 30. During assembly, the light emitting module 20 may be snapped onto the top cover 30 first, and the light emitting module 20 and the top cover 30 may be mounted onto the radiator body 10 together by utilizing the see-through feature of the transparent cover.
[0061] The other structures of this embodiment are the same as those of the first embodiment and can also achieve the beneficial effects of the first embodiment, so they will not be described in detail.
[0062] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0063] The above embodiments only express the preferred implementation of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
