Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat sinks, in particular to a heat sink and a light supplementing lamp. BACKGROUND

[0002] The light supplementing lamp is a device for providing an additional light source, which is usually used in shooting or working environment to help improve the lighting conditions, increase the brightness of the scene, fill in the shadows, etc.

[0003] In the prior art, the heat sink is usually provided with a fan, a substrate and heat dissipation fins, wherein the substrate is used to conduct the heat of the heat source, and the fan and the heat dissipation fins are used to help the substrate dissipate heat. Such a heat sink can only dissipate heat for the part of the heat source in contact with the substrate, and the heat dissipation effect is very limited due to the heat conduction area of the substrate. Moreover, the airflow generated by the fan cannot directly dissipate heat for the heat source due to the obstruction of the substrate, thereby affecting the heat dissipation effect of the heat sink. The heat source of the light supplementing lamp mainly comes from the light source and light efficiency accessories, and the contact part of the heat source with the heat sink is relatively limited, thereby affecting the heat dissipation effect of the light supplementing lamp.

[0004] Therefore, there is a need for a solution to solve at least one of the above problems. CONTENT OF THE INVENTION

[0005] In view of the defects in the prior art, the present application provides a heat sink and a light supplementing lamp, which improves the airflow circulation channel and realizes multi-dimensional heat dissipation air duct, thereby increasing the circulation range of the airflow and having good heat dissipation effect.

[0006] Firstly, the present application provides a heat sink, which comprises a main heat dissipation substrate, main heat dissipation fins and a fan.

[0007] One side of the main heat dissipation substrate is provided with a heat conduction area, and the other side is provided with a heat dissipation area.

[0008] The heat conduction area is used to connect the heat source and conduct the heat to the heat dissipation area. The heat dissipation area is provided with a plurality of main heat dissipation fins, and a heat dissipation gap is formed between adjacent main heat dissipation fins. The fan is arranged in the heat dissipation area to form a first heat dissipation air duct which is in communication with the outside through the heat dissipation gap.

[0009] The equidistant arrangement of the main heat dissipation fins effectively increases the surface area of the heat dissipation area of the heat sink, improves the heat dissipation efficiency, and forms uniform heat dissipation gaps. The first heat dissipation air duct is formed, so that the forced airflow fully contacts the surface of the main heat dissipation fins, thereby improving the heat exchange effect.

[0010] A plurality of ventilation holes are further arranged on the main heat dissipation substrate, which are in communication with the heat dissipation gap and the heat source to form a second heat dissipation air duct from the heat dissipation area to the heat source.

[0011] The fan is used to provide forced air flow to accelerate the flow speed of the air flow, thereby effectively improving the heat dissipation speed; the ventilation hole is arranged on the main heat dissipation base plate, which can weaken the blockage of the forced air flow by the heat dissipation base plate, so that the air flow can directly dissipate heat from the heat source through the second heat dissipation air duct, and on the whole, the first heat dissipation air duct and the second heat dissipation air duct realize multi-dimensional heat dissipation paths, improve the heat dissipation range of the heat dissipation device, and thus improve the heat dissipation efficiency.

[0033] The reflective cup is provided on the lamp panel of the light source, and the extension direction of the ventilation hole is towards the outer wall of the reflective cup;

[0034] The design of the ventilation hole extending towards the reflective cup enables the forced air flow to be directed to the heat dissipation of the reflective cup as a heat source, thereby optimizing the heat dissipation system of the light supplementing lamp.

[0035] The support ring is sleeved on the reflective cup, and the support ring is provided with an air outlet window.

[0036] The air outlet window is provided on the support ring to strengthen the circulation of air flow in the reflective cup part, so that the air flow between the reflective cup and the support ring can circulate and exchange with the outside, improving the air flow circulation speed and efficiency, and thereby improving the heat dissipation efficiency of the light supplementing lamp.

[0071] Embodiments

[0072] First, the present application provides a heat sink, as shown in the accompanying drawings, comprising: a main heat dissipation substrate 1, a main heat dissipation fin 2 and a fan 13; Figures 1 to 4

[0073] One side of the main heat dissipation substrate 1 is provided with a heat conduction area 11, and the other side is provided with a heat dissipation area 12;

[0074] The heat conduction area 11 is used to connect the heat source 3 and conduct heat to the heat dissipation area 12, the heat dissipation area 12 is provided with the main heat dissipation fin 2, the adjacent main heat dissipation fins 2 form a heat dissipation gap 21, all the main heat dissipation fins 2 are arranged equidistantly to form a relatively uniform heat dissipation gap 21 between adjacent main heat dissipation fins 2, and the fan 13 is arranged in the heat dissipation area 12 to form a first heat dissipation air duct 91 which is in communication with the outside through the heat dissipation gap 21 from the fan 13;

[0075] ​It can be understood that the main heat dissipation fins 2 are equidistantly arranged, which optimizes the layout of the main heat dissipation fins 2 on the main heat dissipation substrate 1, effectively increases the heat dissipation area of the heat dissipation area 12 within the limited space range of the main heat dissipation substrate 1, and improves the heat dissipation efficiency to a certain extent; and the equidistant arrangement of the main heat dissipation fins 2 also forms uniform heat dissipation gaps 21, which helps the airflow to flow between the main heat dissipation fins 2 through the heat dissipation gaps 21 and promotes heat exchange of the airflow; the first heat dissipation air duct 91 is formed, so that the forced airflow fully contacts the surface of the main heat dissipation fin 2, improves the heat exchange effect, and further improves the heat dissipation quality and heat dissipation effect of the heat dissipation device.

[0076] Specifically, in some embodiments of the present application, one side of the main heat dissipation substrate 1 provided with the heat conduction area 11 can also be connected with a heat conduction structure, and the heat source 3 is connected through the heat conduction structure. The heat conduction structure can be made of metal materials such as copper, aluminum or copper-aluminum alloy.

[0077] Specifically, in some embodiments of the present application, the heat source 3 mainly refers to the main heat source in the equipment. For example, the light supplementing lamp is taken as an example, that is, the lamp body component, the lamp panel 51 or the circuit board and the like.

[0078] Of course, whether the heat conduction structure is provided or not, and the specific material of the heat conduction structure, the specific object of the heat source 3 is not limited.

[0079] The main heat dissipation substrate 1 is also provided with a plurality of ventilation holes 14, and the ventilation holes 14 are communicated with the heat dissipation gaps 21 and the heat source 3, so as to form the second heat dissipation air duct 92 from the heat dissipation area 12 to the heat source 3.

[0080] The fan 13 is used to provide forced airflow to accelerate the flow speed of the airflow, thereby effectively improving the heat dissipation speed.

[0081] Specifically, in some embodiments of the present application, the fan 13 can be an electric fan.

[0082] Of course, the specific implementation structure of the fan 13 is not limited.

[0083] The main heat dissipation substrate 1 is provided with the ventilation hole 14, which can reduce the blockage of the forced airflow by the heat dissipation substrate, so that the airflow can directly dissipate heat to the heat source 3 through the second heat dissipation air duct 92.

[0084] Compared with the original heat dissipation mode through heat conduction to the heat dissipation device, the airflow directly dissipates heat to the heat source 3 through the second heat dissipation air duct 92, which is more immediate and accelerates the flow of air, which can avoid the accumulation of heat on the heat source 3 to a certain extent and reduce the possibility of damage to the components due to delayed heat dissipation.

[0085] On the other hand, the first heat dissipation air duct 91 and the second heat dissipation air duct 92 realize multi-dimensional heat dissipation paths as a whole, wherein the first heat dissipation air duct 91 is mainly used for heat conduction of the heat source 3 to the main heat dissipation fins 2, and the heat dissipation of the main heat dissipation fins 2 is realized by heat conduction; the second heat dissipation air duct 92 is mainly used for guiding the airflow to the heat source 3, and the heat dissipation is realized by heat exchange between the heat source 3 and the airflow, mainly by air flow heat exchange. The first heat dissipation air duct 91 and the second heat dissipation air duct 92 improve the heat dissipation range of the heat dissipation device and enrich the heat dissipation mode of the heat source 3, thereby improving the heat dissipation efficiency of the heat dissipation device.

[0086] Further, at least heat dissipation gaps 21 extending in two non-parallel directions are formed between all the main heat dissipation fins 2.

[0087] The extension directions of the heat dissipation gaps 21 are different, which increases the flow path of the forced airflow, optimizes the layout of the main heat dissipation fins 2 on the main heat dissipation substrate 1, and can more effectively conduct heat to a wider area and increase the heat dissipation area in different directions, thereby accelerating the dissipation of heat.

[0088] Specifically, in some embodiments of the present application, the included angle between the heat dissipation gaps 21 with different extension directions is a right angle.

[0089] Of course, the specific extension direction of the heat dissipation gap is not limited.

[0090] Further, the air outlet direction of the fan 13 is parallel to the axial direction of the vent hole 14.

[0091] The arrangement of the air outlet direction of the fan 13 and the direction of the vent hole 14 helps to weaken the blocking effect of the main heat dissipation substrate 1 on the forced airflow in the area of the vent hole 14, avoiding unnecessary airflow deflection, which reduces the air flow resistance and makes the air flow smoother, improves the air passing speed and amount, and thereby improves the air circulation efficiency.

[0092] The air outlet direction of the fan 13 is parallel to the vent hole 14, which can also reduce the sharp change or sudden change in direction of the airflow to some extent, thereby effectively reducing the noise caused by airflow bending and collision.

[0093] Further, all the vent holes 14 are arranged close to the heat conduction area 11.

[0094] The design of the vent hole 14 close to the heat conduction area 11 enables the airflow to cover the entire heat source 3 area more evenly, promotes the heat exchange between the airflow and the heat source 3, can prevent local overheating to some extent, improves the heat dissipation efficiency, and maintains the stability of the equipment function;

[0095] It also helps to expand the heat exchange area, so that the airflow is more orderly, thereby improving the efficiency of heat dissipation and heat exchange; by uniformly distributing the airflow, the phenomenon of uneven temperature is avoided, further improving the stability of the equipment.

[0096] The position of the vent hole 14 avoids the heat conduction area 11, that is, the area where the heat source 3 contacts the main heat dissipation substrate 1, thereby maintaining the original heat conduction area of the heat conduction area 11 and reducing the impact of the setting of the vent hole 14 on the heat conduction function of the heat conduction area 11, so that a better heat conduction efficiency can be achieved.

[0097] Secondly, on the basis of the first part, a secondary radiator 4 is further provided;

[0098] The secondary radiator 4 includes a secondary heat dissipation substrate 41 and a plurality of secondary heat dissipation fins 42 arranged on the secondary heat dissipation substrate 41, the side of the secondary heat dissipation fins 42 away from the secondary heat dissipation substrate 41 faces the main heat dissipation fins 2, and the heat dissipation air ducts in the secondary radiator 4 are respectively communicated with the heat source 3 and the first heat dissipation air duct 91 to form a third heat dissipation air duct 93.

[0099] Specifically, the general direction of the first heat dissipation air duct 91, the second heat dissipation air duct 92 and the third heat dissipation air duct 93 can refer to Figure 2 and Figure 4 the direction of the arrow in the figure.

[0100] Optionally, the secondary heat dissipation substrate 41 can include a plurality of secondary heat dissipation substrates 41 arranged along the circumferential direction of the main heat dissipation substrate 1 to wrap the main heat dissipation substrate 1.

[0101] Specifically, in some embodiments of the present application, the secondary heat dissipation substrate 41 is provided with one, and the arrangement direction of the secondary heat dissipation fins 42 on the secondary heat dissipation substrate 41 is perpendicular to the arrangement direction of the main heat dissipation fins 2 on the main heat dissipation substrate 1.

[0102] Of course, the specific number of secondary heat dissipation substrates 41 and the specific arrangement direction of secondary heat dissipation fins 42 are not limited.

[0103] The arrangement of the secondary heat dissipation substrate 41, on the one hand, increases the heat conduction area of the radiator, and the expansion of the heat conduction area helps to improve the heat conduction efficiency and accelerate the heat conduction speed of the heat source 3, thereby improving the overall heat dissipation efficiency;

[0104] On the other hand, the heat conduction point or heat conduction site of the radiator is increased, which is located at different positions of the radiator, and can conduct heat to the heat source 3 at different positions, thereby adapting to the heat conduction needs of different internal structures of the equipment;

[0105] The heat dissipation air ducts in the auxiliary heat sink 4 are in communication with the heat source 3 and the first heat dissipation air duct 91 respectively to form a third heat dissipation air duct 93; the heat dissipation air ducts in the auxiliary heat sink 4 are composed of the heat dissipation gaps 21 formed by the auxiliary heat dissipation fins 42;

[0106] The third heat dissipation air duct 93 reduces the obstruction to the airflow and facilitates the passing of the airflow. In the third heat dissipation air duct 93, the heat dissipation gaps 21 on the main heat dissipation base plate 1 are in communication with the heat dissipation gaps 21 on the auxiliary heat dissipation base plate 41, so that the airflow is forced to pass through the main heat dissipation fins 2 on the main heat dissipation base plate 1 and dissipate heat for them;

[0107] After being forced to pass through the main heat dissipation base plate 1, the airflow is at least partially obstructed by the auxiliary heat dissipation base plate 41 and dissipates heat for the auxiliary heat dissipation fins 42 on the auxiliary heat dissipation base plate 41;

[0108] The airflow forced to pass through the heat dissipation gaps 21 formed by the auxiliary heat dissipation fins 42 on the auxiliary heat dissipation base plate 41 flows to the heat source 3 for heat exchange, effectively improving the utilization rate of the forced airflow and further realizing direct heat exchange dissipation for the heat source 3 through the third heat dissipation air duct 93, optimizing the heat dissipation capacity of the heat sink and further improving the heat dissipation effect of the heat sink.

[0109] Further, as shown in Figure 3 , the main heat dissipation base plate 1 extends outward to form mounting portions 15 for mounting the auxiliary heat dissipation base plate 41.

[0110] The above structure is arranged such that the mounting portions 15 form accommodating spaces therebetween, which can be used to accommodate the auxiliary heat dissipation fins 42 on the auxiliary heat dissipation base plate 41 and facilitate the circulation of the airflow, to a certain extent, avoiding the obstruction of the airflow by the main heat dissipation base plate 1.

[0111] Moreover, the arrangement of the mounting portions 15 facilitates the connection of the main heat dissipation base plate 1 and the auxiliary heat dissipation base plate 41, increases the connection force points and improves the stability of the connection state of the main heat dissipation base plate 1 and the auxiliary heat dissipation base plate 41.

[0112] The embodiment also provides a light supplementing lamp, as shown in Figures 5 to 9 , comprising:

[0113] a heat sink according to any one of the preceding first part and second part,

[0114] a light source 5 connected with the heat conduction area 11;

[0115] a lampshade 6 arranged on the light source 5;

[0116] a control module 7 electrically connected with the heat sink and the light source 5, for controlling the opening and closing of the light source 5 and the driving of the fan 13 on the heat sink or not;

[0117] A lamp shell 8 is used to accommodate the heat sink and the control module 7.

[0118] Specifically, in some embodiments of the present application, the light source 5 can be a lamp body.

[0119] Of course, the specific structure of the light source 5 is not limited.

[0120] Through the structural arrangement of the heat sink, good heat dissipation effect is obtained, thereby improving the overall heat dissipation efficiency of the light supplementing lamp.

[0121] Specifically, the flow direction of the forced air flow of the light supplementing lamp is as shown by the arrowhead in Figure 8 and Figure 9 .

[0122] Further, as shown in Figure 6 and Figure 7 , the lamp cover 6 comprises a reflecting cup 61 and a supporting ring 62.

[0123] The reflecting cup 61 is arranged on the lamp panel 51 of the light source 5, and the extension direction of the air vent 14 is towards the outer wall of the reflecting cup 61.

[0124] It can be understood that the reflecting cup 61 is used to reflect light, and since the light is irradiated on the surface of the reflecting cup 61, heat is easily accumulated in the reflecting cup 61, which can be regarded as a component part of the heat source 3.

[0125] The design that the extension direction of the air vent 14 is towards the reflecting cup 61 helps to optimize the air flow, so that the forced air flow can be used to dissipate heat for the reflecting cup 61 as the heat source 3, and the conduction speed of the heat on the reflecting cup 61 is accelerated, thereby optimizing the heat dissipation system of the light supplementing lamp.

[0126] Since the reflecting cup 61 itself has a relatively high surface temperature, reasonable ventilation design can reduce the risk of overheating, thereby maintaining the stable operation of the light supplementing lamp.

[0127] The supporting ring 62 is sleeved on the reflecting cup 61, and the supporting ring 62 is provided with an air outlet window 621.

[0128] The air outlet window 621 is arranged on the supporting ring 62, which strengthens the flow of the air flow of the reflecting cup 61, so that the air flow between the reflecting cup 61 and the supporting ring 62 can flow and exchange with the outside, thereby improving the flow speed and flow efficiency of the air flow, and further improving the heat dissipation efficiency of the light supplementing lamp.

[0129] Specifically, in some embodiments of the present application, all the air outlet windows 621 are uniformly arranged along the circumferential direction of the supporting ring 62.

[0130] Further, as shown in Figure 6As shown, the lamp shell 8 is further provided with a plurality of external connection structures 81, which are uniformly arranged around the support ring 62, and at least part of the air outlet window 621 faces the space between the plurality of external connection structures 81.

[0131] Specifically, in some embodiments of the present application, the external connection structure 81 is a buckle structure, which is arranged equidistantly and symmetrically around the ring line.

[0132] Of course, the specific form of the external connection structure 81 is not limited.

[0133] It can be understood that the external connection structure 81 is uniformly arranged around the support ring 62, which enhances the physical stability of the overall structure of the light supplement lamp. The external connection structure 81 is uniformly distributed around the support ring 62, which can provide uniform support for the lamp. The plurality of external connection structures 81 can also disperse the load borne by the lamp, reducing the uneven effect of external force on the lamp.

[0134] And the external connection structure is used to connect the lamp body accessories to improve the light effect or realize diversified light effect. The dispersed arrangement of the external connection structure 81 avoids the shielding of the air outlet window 621 to a certain extent, thereby reducing the obstruction of the airflow, making the airflow circulation at the air outlet window 621 more smooth.

[0149] On the other hand, the arrangement of the air outlet 83 increases the ventilation area of the light supplement lamp, and helps to improve the ventilation amount and efficiency.
