[0002] Currently, demands for ever-increasing refinement and aesthetics in vehicle design are driving the trend toward miniaturization of optical modules in vehicle front lights. For lamps that require integrated high- and low-beam functions, the compact design of multiple functional modules presents significant heat dissipation challenges. Current cooling modules with fans reduce the gap between the fan and the radiator as the lamp's form factor shrinks, making it difficult for the fan to drive airflow across the entire radiator's area. Furthermore, the fan can only actively dissipate heat on one side of the radiator, making it difficult to dissipate heat within the lamp, resulting in poor cooling performance.

[0026] The core of the utility model lies in disclose a heat dissipation structure, lamps and lanterns and vehicle to improve the heat dissipation effect of lamps and lanterns.

[0027] In order to make the personnel in the prior art better understand the utility model scheme, the utility model embodiment is explained below with reference to the drawings, and in addition, the embodiment shown below does not have any limiting effect on the utility model content recorded in the claims.

[0028] In addition, the constitution of the embodiment shown below is not limited to the solution of the utility model recorded in the claims.

[0029] As Figures 1-7 The heat dissipation structure provided by the utility model embodiment mainly includes fan module 10 and fan heater module, wherein fan module 10 is used to blow airflow to flow towards radiator module 20 to realize efficient heat exchange.

[0030] And considering the gradually tense interior space design of lamps and lanterns, in the heat dissipation structure provided by the utility model embodiment, radiator module 20 adopts horn-shaped structure, that is, radiator module 20 has two end structures of different sizes, and the smaller end of radiator module 20 is arranged close to fan module 10 to receive most of the airflow, and preferably, the smaller end of radiator module 20 is sleeved on the outer wall of the opposite two sides of fan module 10 to make the airflow blown by fan module 10 be received by radiator module 20; and correspondingly, the larger end of radiator module 20 is arranged close to the heating component to directly exchange heat with the heating component, and has greater heat exchange area, so as to improve the stability of radiator module 20 in heat absorption process. The structure of radiator module 20 can effectively guide airflow, and for the structure that radiator module 20 is larger than fan module 10, the outflow area of fan module 10 does not need to be increased, but all air volume is received through horn-shaped design structure, so as to optimize the airflow blowing effect of fan module 10 on radiator module 20, improve the heat dissipation efficiency of the heat dissipation structure, and at the same time, the heat dissipation structure does not need to occupy additional space, and can be compactly installed in various devices.

[0031] Further, in the heat dissipation structure provided by the embodiment of the utility model, the radiator module 20 includes a plurality of interval arranged heat dissipation fins 210, so as to improve the contact area of the air flow of the radiator module 20 and the fan module 10 through the heat dissipation fins 210, and improve the heat dissipation efficiency of the radiator module 20. On this basis, at least part of the heat dissipation fins 210 is provided with a guide section 220 and a flow dividing section 230 along the first direction, and it needs to be explained that the first direction here specifically refers to the direction of the fan module 10 towards the larger end of the radiator module 20, and the structure design of the guide section 220 and the flow dividing section 230 is to further improve the air flow uniformity in the radiator module 20.

[0032] Specifically, the flow dividing sections 230 are arranged in parallel, and preferably, the flow dividing sections 230 between adjacent heat dissipation fins 210 are equal in interval, the flow dividing section 230 is arranged on the side closer to the heat generating component compared with the guide section 220 and perpendicular to the outflow surface of the fan module 10, so as to provide a uniform channel for the air flow to the heat generating component area and maintain uniform heat dissipation effect; and the guide section 220 is arranged at an angle with the flow dividing section 230, and the guide section 220 is arranged closer to the fan module 10 compared with the flow dividing section 230, so as to guide and divide the outflow gas of the fan module 10 through the guide section 220.

[0033] And it needs to be explained that among the heat dissipation fins 210 located at different positions, the included angle of the guide section 220 and the flow dividing section 230 is different, and specifically, the obtuse angle included angle of the guide section 220 and the flow dividing section 230 is inversely proportional to the distance between the corresponding heat dissipation fin 210 and the center of the fan module 10; that is, the farther the heat dissipation fin 210 is from the center of the fan module 10, the smaller the bending shape is, and among the heat dissipation fins 210 located in the central area of the fan module 10, the included angle of the guide section 220 and the flow dividing section 230 is close to 180 degrees, or the guide section 220 and the flow dividing section 230 remain parallel extension structure. For the heat dissipation fins 210 staggered with the central area of the fan module 10, the air flow is guided and divided through the guide section 220 bent relative to the flow dividing section 230, and the heat dissipation fin 210 close to the central area needs to maintain a larger deflection angle compared with the heat dissipation fin 210 far from the central area, so as to avoid that the small deflection angle causes the air volume to be unable to enter the heat dissipation fin 210 close to the central area, thereby improving the air flow uniformity of the heat dissipation fins 210 in each area. And preferably, the heat dissipation fins 210 in the radiator module 20 are symmetrically arranged about the fan module 10, and the air flow uniformity of the radiator module 20 is further improved.

[0034] Further, on the basis of the above-mentioned embodiments, in order to avoid the problem of excessive turbulence caused by excessive blocking of the air flow of the fan module 10 due to the folding arrangement of the excessive heat dissipation fins 210, in some embodiments of the present application, only one of the two adjacent heat dissipation fins 210 is provided with a guide section 220 and a flow dividing section 230 to divide the air flow, and the other heat dissipation fin 210 is only provided with a guide section 220. By alternating arrangement, the blocking of the air flow is avoided, the flow rate is not affected, and the manufacturing cost and complexity are reduced.

[0035] Further, in the heat dissipation structure provided by the embodiments of the present application, the heat sink module 20 further comprises a flow dividing layer 260, which is a single-layer plate structure and divides the heat dissipation fins 210 in the second direction. It should be noted that the second direction is the height direction of the single heat dissipation fin 210, i.e. the second direction is perpendicular to the first direction.

[0036] Correspondingly, at least part of the heat dissipation fins 210 are arranged in layers along the second direction and are provided with a first guide layer 240 and a second guide layer 250, and the first guide layer 240 and the second guide layer 250 are located on both sides of the flow dividing layer 260 and are in contact with the flow dividing layer 260. The flow dividing layer 260 is specifically provided with a heat dissipation area 2610, which is used for fixedly arranging the heat generating components, so that the heat generating components can quickly transfer heat to the heat dissipation fins 210 by fixed conduction. The layering of the flow dividing layer 260 and part of the heat dissipation fins 210 in the second direction allows the air flow blown by the fan module 10 to pass through the first guide layer 240 in the second direction, and the other part to pass through the second guide layer 250. Based on the position of the heat dissipation area 2610, the heat generating components on the heat dissipation area 2610 will have air flow passing through on both sides in the second direction. Compared with the current one-way air blowing heat dissipation method, the fan module 10 can achieve the effect of blowing air on both sides of the heat generating components, and the air flow of the fan module 10 can directly reach the position of the heat generating components, further improving the heat dissipation effect of the heat generating components.

[0037] In order to further optimize the above-mentioned embodiment, the second guide layer 250 is also designed as an inclined structure, specifically, the second guide layer 250 is a structure that is contracted towards the heat dissipation area 2610 in the first direction; correspondingly, the heat dissipation structure includes a cover body 30 that is connected with the heat dissipation module 20, the cover body 30 is a structure for protecting the heat dissipation module 20, the fan module 10 and the heat generating component, and the cover body 30 is specially provided with a recessed part, the recessed part is recessed towards the heat dissipation module 20 to be attached to the top wall surface of the second guide layer 250 in the second direction, so as to cooperate with the second guide layer 250 to form a plurality of auxiliary heat dissipation air ducts that are contracted towards the heat dissipation area 2610 in the first direction. The setting of the recessed part can make the adjacent two second guide layers 250 cooperate with the flow distribution layer 260 to form a triangular structure air duct, the large opening position of the air duct is towards the fan module 10 to receive the airflow, and the small opening position of the air duct is towards the heat dissipation area 2610, and due to the contraction structure of the air duct, the airflow is accelerated to the position of the heat generating component under the blowing of the fan module 10, so as to achieve the heat dissipation of the heat generating component.

[0038] It should be noted that the flow outlet 2620 is correspondingly arranged on the flow distribution layer 260, so that after the airflow passing through the second guide layer 250 and performing heat exchange, the airflow can be discharged from the position of the flow outlet 2620, thereby avoiding the accumulation of high-temperature gas in the equipment to affect the heat exchange effect of the heat generating component.

[0039] Further, in some embodiments of the utility model, the first guide layer 240 is connected to the flow distribution layer 260, so that the airflow can be guided by the first guide layer 240 before reaching the flow distribution layer 260; at the same time, the heat dissipation area 2610 is preferably arranged in an inclined manner in the first direction to reduce the air outlet position of the first guide layer 240, which can make the air duct structure formed by the adjacent first guide layers 240 contract towards the heat dissipation area 2610, thereby accelerating the flow rate of the airflow between the first guide layers 240, so as to achieve the effect of accelerating heat dissipation; at the same time, the inclined arrangement of the heat dissipation area 2610 can also make the heat generating component be installed in an inclined manner, so as to have a larger contact area with the airflow passing horizontally, thereby improving the heat dissipation efficiency.

[0040] It should be noted that in the above-mentioned embodiment, for the heat dissipation fin 210, the layered structure thereof in the first direction is the guide section 220 and the flow distribution section 230, and the layered structure thereof in the second direction is the first guide layer 240 and the second guide layer 250, both of which can be separately arranged to optimize the heat dissipation effect of the heat dissipation structure; at the same time, both of which can also be synchronously arranged on one heat dissipation fin 210, and the heat dissipation fin 210 has layered structures in the first direction and the second direction, which will not be described here.

[0041] In addition, since the fan module 10 is mainly arranged towards the first guide layer 240 of the heat dissipation fin 210, the air volume of the fan module 10 reaching the second guide layer 250 is less, and in order to avoid the excessive arrangement of the second guide layer 250 affecting the heat dissipation effect due to the blockage of the air flow, in some embodiments of the present application, one of the two adjacent heat dissipation fins 210 is provided with the first guide layer 240 and the second guide layer 250, and the other heat dissipation fin 210 is only provided with the first guide layer 240, so as to improve the spacing between the two adjacent second guide layers 250 and improve the air volume.

[0042] Further, in the heat dissipation structure provided in the embodiments of the present application, the spacing between the fan module 10 and the heat dissipator module 20 in the first direction is 15-25mm, so that the heat dissipation structure will not be too large due to the spacing, and at the same time, the spacing can also be maintained so that the output air flow of the fan module 10 can be well diffused to the surrounding, and the demand for shunt heat dissipation can be met.

[0043] Further, the embodiments of the present application also provide a lamp, which comprises a lamp panel 40 and the heat dissipation structure provided in any one of the above embodiments, and the lamp panel 40 is close to or contacts the larger end of the heat dissipator module 20 in the heat dissipation structure for heat dissipation. Since the heat dissipation structure has the technical effects provided in any one of the above embodiments, the lamp also has the above technical effects, which will not be described herein again.

[0044] In addition, the embodiments of the present application also provide a vehicle, which comprises the lamp provided in any one of the above embodiments, and since the lamp has the technical effects provided in any one of the above embodiments, the vehicle also has the above technical effects, which will not be described herein again.

Therefore, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features.

The present application can be variously changed and modified by those skilled in the art. The scope of the present application is not limited to the technical solutions formed by the specific combinations of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or equivalent features without departing from the above inventive concept.
