Description
Technical Field
[0001] The present application relates to the technical field of heat dissipation of vehicle lamps, and in particular to a heat dissipation copper tube, a heat dissipation component and a vehicle lamp. Background Art
[0002] At present, with the development of car lighting technology, car lights are no longer satisfied with the pursuit of good lighting effects, but through the projection function to achieve a variety of practical and entertaining special effects. For example, by illuminating concrete symbols and logos on the ground to achieve communication between people and cars.
[0003] In order to achieve the best projection performance, the power of the headlight needs to be kept at a high value. However, the heat dissipation effect of the headlight in the related art is average, which can easily lead to damage of the headlight due to overheating. Utility Model Content
[0004] The present application provides a heat dissipation copper tube, a heat dissipation component and a car lamp, which can effectively improve the heat dissipation effect of the car lamp, reduce the probability of damage to the car lamp due to overheating, and increase the service life of the car lamp.
[0005] In a first aspect, the present application provides a heat dissipation copper tube, comprising:
[0006] Heat absorption pipe section;
[0007] The heat dissipation pipe section is spaced apart from the heat absorption pipe section; and
[0008] A connecting pipe section, two ends of which are respectively connected to the heat absorbing pipe section and the heat dissipating pipe section;
[0009] Wherein, a microchannel is formed on the inner wall of the heat dissipation copper tube, and the interior of the heat dissipation copper tube is a negative pressure environment and is filled with coolant.
[0010] In the solution provided by the present application, when the heat generated by the headlight is transferred to the heat absorbing pipe section of the heat dissipation copper tube, the coolant in the heat absorbing pipe section under negative pressure is evaporated by heat, and flows from the heat absorbing pipe section to the heat dissipation pipe section through the connecting pipe section. The temperature of the heat dissipation pipe section is lower than that of the heat absorbing pipe section, and the gaseous coolant condenses when it encounters cold in the heat dissipation pipe section, and the heat is conducted out of the headlight. Subsequently, the coolant in the heat dissipation pipe section can gradually flow back from the heat dissipation pipe section to the heat absorbing pipe section under the capillary action of the microchannels on the inner wall of the heat dissipation copper tube. Specifically, since the inner wall of the heat dissipation copper tube has many tiny microchannels, the coolant is adsorbed in these tiny microchannels, and under the combined action of the surface tension, cohesion and adhesion of the coolant, it can gradually flow back from the heat dissipation pipe section to the heat absorbing pipe section. Therefore, the coolant can circulate back and forth in the heat absorbing pipe section and the heat dissipation pipe section, thereby continuously transferring the heat generated by the headlight from the heat absorbing pipe section to the heat dissipation pipe section and dissipating it to the outside of the headlight. It can be seen that this solution can effectively improve the heat dissipation effect of the headlights, reduce the probability of damage to the headlights due to overheating, and increase the service life of the headlights.

[0014] In combination with the first aspect and the above-mentioned implementations, in some possible implementations, the heat absorption pipe section is flat, and two opposite surfaces of the heat absorption pipe both have the fitting plane.

[0033] The following embodiments of the technical solution of the present application are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.
[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.
[0035] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0036] At present, with the development of car lighting technology, car lights are no longer satisfied with the pursuit of good lighting effects, but through the projection function to achieve a variety of practical and entertaining special effects. For example, by illuminating concrete symbols and logos on the ground to achieve communication between people and cars.
[0037] In order to achieve the best projection performance, the power of the headlight needs to be kept at a high value. However, the heat dissipation effect of the headlight in the related art is average, which can easily lead to damage of the headlight due to overheating.
[0038] In order to solve the above technical problems, the present application provides a heat dissipation copper tube, a heat dissipation component and a car light, which can effectively improve the heat dissipation effect of the car light, reduce the probability of damage to the car light due to overheating, and increase the service life of the car light.
[0039] The heat dissipation copper tube, heat dissipation assembly and vehicle lamp provided in the embodiments of the present application are first introduced in detail below with reference to the drawings in the specification.
[0040] First, please refer to Figures 1 to 3 In the first aspect of the present application, a heat dissipation copper tube 410 is proposed, which includes a heat absorbing tube section 411, a heat dissipation tube section 412 and a connecting tube section 413. The heat dissipation tube section 412 is spaced relative to the heat absorbing tube section 411; the connecting tube section 413 and the two ends of the connecting tube section 413 are respectively connected to the heat absorbing tube section 411 and the heat dissipation tube section 412; the inner wall of the heat dissipation copper tube 410 is formed with microchannels, and the interior of the heat dissipation copper tube 410 is a negative pressure environment and is filled with coolant. The coolant can be pure water, or it can be a special coolant such as alcohol type or glycerin type. The negative pressure state inside the heat dissipation copper tube 410 can reduce the boiling point of the coolant inside the heat dissipation copper tube 410.
[0041] In the solution provided by the embodiments of the present application, when the heat generated by the vehicle lamp is transferred to the heat absorption pipe section 411 of the heat dissipation copper pipe 410, the coolant in the negative pressure environment inside the heat absorption pipe section 411 is heated and evaporated, and flows from the heat absorption pipe section 411 to the heat dissipation pipe section 412 through the connecting pipe section 413. The temperature of the heat dissipation pipe section 412 is lower than that of the heat absorption pipe section 411, and the gaseous coolant condenses when it meets the heat dissipation pipe section 412, and the heat is exported from the vehicle lamp. Subsequently, the coolant in the heat dissipation pipe section 412 can gradually flow back from the heat dissipation pipe section 412 to the heat absorption pipe section 411 under the capillary action of the microchannels on the inner wall of the heat dissipation copper pipe 410. Specifically, since there are many fine microchannels on the inner wall of the heat dissipation copper pipe 410, the coolant is adsorbed in these fine microchannels, and under the combined action of the surface tension, cohesion and adhesion of the coolant, it can gradually flow back from the heat dissipation pipe section 412 to the heat absorption pipe section 411. Therefore, the coolant can circulate reciprocally between the heat absorption pipe section 411 and the heat dissipation pipe section 412, so as to continuously transfer the heat generated by the vehicle lamp from the heat absorption pipe section 411 to the heat dissipation pipe section 412 and dissipate it outside the vehicle lamp. It can be seen that through this solution, the heat dissipation effect of the vehicle lamp can be effectively improved, the probability of the vehicle lamp being damaged due to overheating can be reduced, and the service life of the vehicle lamp can be improved.
[0042] It can be understood that the structure of the heat dissipation copper pipe 410 can be various. In a possible implementation manner, the heat dissipation copper pipe 410 can be bent twice to form a structure similar to a "匚" shape. In addition, the heat absorption pipe section 411 and the heat dissipation pipe section 412 of the heat dissipation copper pipe 410 can be arranged in a staggered manner. For example, referring to Figure 3 , Figure 3 is Figure 1 the rear view of the heat dissipation component with the heat dissipation fins omitted. In some embodiments of the present application, in the vertical direction, the heat absorption pipe section 411 can be set higher or lower relative to the heat dissipation pipe section 412. Among them, for the connecting pipe section 413 connecting the heat absorption pipe section 411 and the heat dissipation pipe section 412, the connecting pipe section 413 can be set at an angle with both the heat absorption pipe section 411 and the heat dissipation pipe section 412. Exemplarily, referring to Figure 2 , Figure 2 is Figure 1 the structural schematic diagram of the heat dissipation component with the heat dissipation fins omitted, the connecting pipe section 413 can be set perpendicular to both the heat absorption pipe section 411 and the heat dissipation pipe section 412. In addition, it can also be set as an acute angle or an obtuse angle according to actual needs, and the embodiments of the present application do not make specific limitations in this regard.
[0043] In order to improve the heat dissipation efficiency, the heat absorbing pipe section 411 may have a fitting plane. The fitting plane is in contact with the light source, which can increase the effective contact area between the heat dissipating copper tube 410 and the light source, thereby improving the heat dissipation efficiency. The heat absorbing pipe section 411 may be a rectangular parallelepiped structure or other structures, such as a flat structure. Considering the convenience of processing and manufacturing the heat absorbing pipe section 411, the heat dissipating copper tube 410 may be a round tube as a whole, and the heat absorbing pipe section 411 may be processed into a flat structure with two relatively fitting planes by stamping, extruding, etc.
[0044] Second, see Figure 2 The second aspect of the present application also proposes a heat dissipation component 401, comprising at least two heat dissipation copper tubes 410 described above. In other words, the heat dissipation copper tubes 410 can be two, three, four, and so on. The heat absorption pipe sections 411 of at least two heat dissipation copper tubes 410 are adjacent and arranged side by side up and down. It can be understood that the multiple heat absorption pipe sections 411 arranged adjacent to each other are arranged more closely, which can better cover the light source and achieve close contact with the light source. The heat absorption pipe sections 411 are arranged side by side up and down, which is also convenient for the installation and fixation of the heat dissipation copper tube 410.
[0045] See also Figure 3 In some embodiments of the present application, in the heat dissipation copper tube 410 located at the top, the heat absorption tube section 411 is located higher than the heat dissipation tube section 412. For example, Figure 3 As shown, for the upper heat dissipation copper tube 410, in the vertical direction, the heat dissipation pipe segment 412 in the upper heat dissipation copper tube 410 can be arranged higher relative to the heat absorption pipe segment 411. In this way, in addition to being affected by the capillary action, the heat dissipation pipe segment 412 can be accelerated to flow back to the heat absorption pipe segment 411 under the action of gravity. Therefore, the coolant in the heat dissipation copper tube 410 can flow back to the heat absorption pipe segment 411 more quickly.
[0046] Please continue to see Figure 3 , in the heat dissipation copper tube 410 located at the bottom, the heat absorption pipe section 411 is lower than the heat dissipation pipe section 412. For the heat dissipation copper tube 410 at the bottom, in order to avoid increasing the ambient temperature around the heat dissipation pipe section 412 of the upper heat dissipation copper tube 410 and affecting the heat dissipation of the upper heat dissipation copper tube 410, the heat dissipation pipe section 412 of the lower heat dissipation copper tube 410 can be farther away from the heat dissipation pipe section 412 of the upper heat dissipation copper tube 410, that is, in the vertical direction, it can be as follows Figure 3 As shown, the heat dissipation pipe section 412 in the lower heat dissipation copper tube 410 is arranged lower than the heat absorption pipe section 411. In this way, sufficient space can be maintained between the heat dissipation pipe section 412 of the upper heat dissipation copper tube 410 and the heat dissipation pipe section 412 of the lower heat dissipation copper tube 410 to avoid affecting the heat dissipation effect of each other.
[0047] See also Figure 1 and Figure 3 In some embodiments of the present application, the heat dissipation component 401 may further include a plurality of heat dissipation fins 420. The plurality of heat dissipation fins 420 are arranged at intervals perpendicular to the heat absorption pipe segment 411 and the connecting pipe segment 413. The heat absorption pipe segment 411 is located at one end of the heat dissipation fin 420. In order to improve the heat dissipation effect, the heat absorption pipe segment 411 may be bonded to one end of the heat dissipation fin 420. As described above, bonding planes may be set on opposite sides of the heat absorption pipe segment 411, one of which is bonded to the light source, and the other is bonded to one end of the heat dissipation fin 420. A through hole 421 for accommodating the heat dissipation pipe segment 412 is provided on the heat dissipation fin 420. For each heat dissipation fin 420, the number of through holes 421 corresponds to the number of heat dissipation copper tubes 410.
[0048] See also Figure 1 and Figure 4 , Figure 4 yes Figure 1 The schematic diagram of the structure of the heat dissipation copper tube is omitted in the heat dissipation component. Figure 1 The heat dissipation assembly 401 shown has two heat dissipation copper tubes 410. Figure 4 There are two through holes 421 on the heat dissipation fin 420. The diameter of the through hole 421 matches the diameter of the heat dissipation copper tube 410. Considering the convenience of installing the heat dissipation copper tube 410, the diameter of the through hole 421 can be set slightly larger than the diameter of the heat dissipation copper tube 410. When in use, the heat dissipation pipe section 412 is inserted into the through hole 421, so that the heat of the heat dissipation pipe section 412 can be better conducted from the heat dissipation fin 420 to the car lamp.
[0049] Finally, an embodiment of the present application also provides a vehicle lamp, comprising the heat dissipation assembly 401 described above.
