Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, and in particular to a heat dissipation structure and a lamp. Background Technology

[0002] During the use of LED lights, the efficiency of converting electrical energy into light energy is not 100%. Some energy is dissipated as heat during the conversion process. Therefore, a heat dissipation structure needs to be incorporated into the LED light. Heat dissipation designs typically include materials such as heat sinks, heat pipes, and aluminum alloy casings. These materials help to quickly transfer heat from the LED chip to the external environment by increasing the surface area or improving thermal conductivity. High-power LED lights, in particular, require additional fans to dissipate heat from the heat sinks and other heat dissipation components.

[0003] However, the airflow direction of existing fans is fixed, and the airflow tends to concentrate in a certain area, resulting in insufficient ventilation in other areas and poor heat dissipation. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a heat dissipation structure that aims to solve the problem in the prior art where the airflow direction of the fan is fixed, the airflow tends to concentrate in a certain area, resulting in insufficient ventilation in other areas and thus poor heat dissipation.

[0005] This utility model provides a heat dissipation structure, including a heat-conducting block, heat dissipation fins, a housing, and a fan structure. The heat dissipation fins are provided in a plurality of configurations, perpendicular to the heat-conducting block, and forming heat dissipation channels between them. The housing is fitted onto the end of each heat dissipation fin furthest from the heat-conducting block. The fan structure includes fan blades, guide vanes, and a mounting shell. The mounting shell is connected to the housing, and the fan blades are disposed on the mounting shell. The guide vanes are rotatably connected to the mounting shell and located at the air outlet end of the fan blades. The fan guides external gas from outside the housing to the heat dissipation fins, and the guide vanes rotate under the drive of the fan to change the direction of gas flow.

[0006] According to some embodiments of the present invention, the heat dissipation fins include rotating fins, which are rotatably connected to the heat-conducting block. The rotating fins are positioned corresponding to the air guide vanes, and the rotating fins are used to rotate when the air guide vanes change the direction of gas flow.

[0007] According to some embodiments of the present invention, the rotating fin has an insertion hole, the heat-conducting block has an insertion shaft, and the rotating fin is inserted into the insertion shaft to rotate.

[0008] According to some embodiments of the present invention, the heat dissipation fins include inner fins and outer fins. The inner fins are located on the outer periphery of the rotating fins, and the outer fins are located on the outer periphery of the inner fins. The heat dissipation channels formed between the inner fins and the heat dissipation channels formed between the outer fins are offset from each other.

[0009] According to some embodiments of the present invention, the inner fin is provided with a first reinforcing rib, which is located in the middle of the inner fin.

[0010] According to some embodiments of the present invention, the outer fin is provided with a second reinforcing rib and a third reinforcing rib, the second reinforcing rib being located in the middle of the outer fin, and the third reinforcing rib being located on the side of the outer fin away from the inner fin.

[0014] This utility model also provides a lamp, including the heat dissipation structure described in any of the above claims.

[0015] Beneficial Effects: This utility model provides a heat dissipation structure, including a base, a housing, and a fan structure. The base includes a heat-conducting block and several heat dissipation fins, which are perpendicular to the heat-conducting block and form heat dissipation channels between them. In this application, because rotatable air guide blades are provided, when the fan guides external air from outside the housing to the heat dissipation fins, the air guide blades rotate under the drive of the fan to change the airflow direction, allowing the airflow to blow in different directions and angles. This allows more heat dissipation channels to benefit from the airflow generated by the fan, effectively avoiding insufficient ventilation in local areas and improving the heat dissipation effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 6 This utility model provides a heat dissipation structure, including a heat-conducting block 1, heat dissipation fins 2, a housing 3, and a fan structure 4. The heat dissipation fins 2 are provided in a plurality of manner, perpendicular to the heat-conducting block 1, and forming a heat dissipation channel 20 between them. The housing 3 is fitted onto the end of the heat dissipation fins 2 away from the heat-conducting block 1. The fan structure 4 includes a fan blade 41, a guide vane 42, and a mounting shell 43. The mounting shell 43 is connected to the housing 3. The fan blade 41 is disposed on the mounting shell 43. The guide vane 42 is rotatably connected to the mounting shell 43 and located at the air outlet end of the fan blade 41. The fan guides external gas from outside the housing 3 to the heat dissipation fins 2. The guide vane 42 rotates under the drive of the fan to change the direction of gas flow.

[0025] In this application, because a rotatable air guide blade 42 is provided, when the fan guides the outside air from the outside of the casing 3 to the heat dissipation fins 2, the air guide blade 42 rotates under the drive of the fan to change the airflow direction, so that the airflow can blow in different directions and angles, so that more heat dissipation channels 20 can benefit from the airflow generated by the fan, effectively avoiding the occurrence of insufficient ventilation in local areas and improving the heat dissipation effect.

[0026] According to some embodiments of this utility model, the heat dissipation fins 2 include rotating fins 21, which are rotatably connected to the heat-conducting block 1. The rotating fins 21 correspond to the positions of the air guide vanes 42, and the rotating fins 21 are used to rotate when the air guide vanes 42 change the direction of gas flow. It can be understood that due to the action of the air guide vanes 42, the direction of airflow is changed, and therefore the rotating fins 21 will also rotate in the changing airflow, thus further disturbing the airflow within the heat dissipation structure, allowing airflow to pass through each heat dissipation channel 20, and improving the uniformity of heat dissipation.

[0027] Specifically, the rotating fin 21 has an insertion hole 211, and the heat-conducting block 1 has an insertion shaft 11. The rotating fin 21 is inserted into the insertion shaft 11 to rotate.

[0028] According to some embodiments of this utility model, the heat dissipation fins 2 include inner fins 22 and outer fins 23. The inner fins 22 are located on the outer periphery of the rotating fins 21, and the outer fins 23 are located on the outer periphery of the inner fins 22. The heat dissipation channels 20 formed between the inner fins 22 and the heat dissipation channels 20 formed between the outer fins 23 are staggered. If the inner fins 22 and the outer fins 23 are arranged in parallel, heat convection dead zones can easily form, which may cause heat to accumulate in certain areas, preventing the heat from dissipating quickly. The staggered design of the inner fins 22 and the outer fins 23 can avoid the above problems. The staggered arrangement allows heat to be distributed and dissipated more evenly, reducing the phenomenon of local overheating.

[0029] According to some embodiments of this utility model, the inner fin 22 is provided with a first reinforcing rib 24, which is located in the middle of the inner fin 22. The first reinforcing rib 24 can enhance the structural strength of the inner fin 22, making it less prone to deformation or damage when subjected to greater mechanical stress or thermal expansion during operation.

[0030] According to some embodiments of this utility model, the outer fin 23 is provided with a second reinforcing rib 25 and a third reinforcing rib 26. The second reinforcing rib 25 is located in the middle of the outer fin 23, and the third reinforcing rib 26 is located on the side of the outer fin 23 away from the inner fin 22. Since the outer fin 23 needs to be connected to the housing 3, it needs to withstand a certain mechanical stress. The second reinforcing rib 25 and the third reinforcing rib 26 can enhance the structural strength of the outer fin 23, enabling the outer fin 23 to withstand greater mechanical stress during operation.

[0031] According to some embodiments of this utility model, the guide vane 42 includes an outer frame 421, longitudinal spacers 422, and transverse spacers 423. The longitudinal spacers 422 and the transverse spacers 423 are staggered and connected to the outer frame 421. A plurality of longitudinal spacers 422 and transverse spacers 423 are provided, and the plurality of longitudinal spacers 422 and the plurality of transverse spacers 423 are evenly spaced. In this embodiment, during rotation, the longitudinal spacers 422 and the transverse spacers 423 can effectively turbulentize the gas, thereby changing the direction of the airflow.

[0032] According to some embodiments of this utility model, the mounting shell 43 is provided with a lower support frame 431, and the lower support frame 431 is provided with a bearing seat 432. The guide vane 42 is rotatably connected to the support frame through the bearing seat 432. In this embodiment, the bearing seat 432 can withstand the axial load from the guide vane 42.

[0033] According to some embodiments of the present invention, the housing 3 is provided with an air inlet 31, and the air inlet 31 corresponds to the position of the fan blade 41.

[0034] This utility model also provides a lamp, including the heat dissipation structure described in any of the above claims. It is understood that in the lamp, the lamp plate is connected to the heat-conducting block 1. Heat emitted by the lamp plate during use can be transferred from the heat-conducting block 1 to the heat dissipation fins 2, and then carried away by the airflow delivered by the fan structure 4.

[0035] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of the equivalent elements of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
