Description

Technical Field

[0001] The present invention relates to the technical field of heat exchange, and particularly relates to a high-efficiency radiator and a stage light applying the high-efficiency radiator. Background Art

[0002] During the operation of the light source of a stage light, a large amount of heat is generated, and the heat needs to be dissipated in time through a radiator. Otherwise, it will affect the stability of the light source performance and also reduce the service life of the light source. Generally, the radiator mainly consists of a first heat sink fin group, a second heat sink fin group, and a third heat sink fin group. The second heat sink fin group and the third heat sink fin group are respectively fixedly arranged on the left and right sides of the first heat sink fin group, and the substrate is fixedly arranged on the top of the first heat sink fin group. Then, only a row of heat dissipation tubes passes through the second heat sink fin group, the substrate, and the third heat sink fins. For example, a light source radiator with a light-shielding function and a stage light having the same disclosed in a Chinese utility model patent (Publication No. CN217843795U) cannot meet the heat dissipation requirements of a high-power light source. Therefore, we need to design a radiator with higher heat dissipation efficiency to meet the needs of high-power light sources. Summary of the Invention

[0021] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following further describes this application in detail with reference to the drawings and specific embodiments.

[0022] As shown in the attached Figure 1 - attached Figure 3As shown in the figure, a high-efficiency radiator includes a first heat sink fin group 1, a second heat sink fin group 2, a third heat sink fin group 3, a substrate 4, and a heat pipe row group 5. The first heat sink fin group 1, the second heat sink fin group 2, and the third heat sink fin group 3 are each formed by a plurality of heat sink fins arranged side by side. There are multiple groups of the heat pipe row group 5, and each group is formed by a plurality of single heat pipes arranged in a row. The second heat sink fin group 2 and the third heat sink fin group 3 are respectively fixedly arranged on the left and right sides of the first heat sink fin group 1. The substrate 4 is attached to the top of the first heat sink fin group 1. The heat pipe row group 5 includes at least two groups of first-group heat pipes passing through the substrate 4. The first-group heat pipes pass through the second heat sink fin group 2 or / and the third heat sink fin group 3. The heat pipe row group 5 further includes at least one group of second-group heat pipes passing through the substrate 4 and not connected to the second heat sink fin group 2 and the third heat sink fin group 3. Compared with the prior art, the radiator of this product includes at least three heat pipe row groups 5, thus greatly increasing the heat conduction efficiency between each heat sink fin group. It can quickly transfer heat energy from the high-energy area to the low-energy area, reducing the temperature of the high-energy area, thereby achieving the purpose of cooling. Furthermore, it enables the heat energy generated by the light source to be effectively removed in a timely manner, ensuring the stability of the light source during operation. At the same time, it avoids damage to the internal parts of the lamp caused by heat energy and extends the service life of the lamp.

[0023] As shown in the attached Figure 2 figure, specifically, the number of the first-group heat pipes is set to two groups, one group is the upper-row heat pipes 51, and the other group is the lower-row heat pipes 52. One end of a part of the upper-row heat pipes 51 passes through the top of the substrate 4, and the other end passes through the second heat sink fin group 2. One end of another part of the upper-row heat pipes 51 passes through the top of the substrate 4, and the other end passes through the third heat sink fin group 3. One end of a part of the lower-row heat pipes 52 passes through the bottom of the substrate 4, and the other end passes through the second heat sink fin group 2. One end of another part of the lower-row heat pipes 52 passes through the bottom of the substrate 4, and the other end passes through the third heat sink fin group 3. This can further increase the heat conduction efficiency between the first-group heat pipes and each heat sink fin group.

[0024] As shown in the attached Figure 2 figure, the upper-row heat pipes 51 of the second heat sink fin group 2 and the upper-row heat pipes 51 of the third heat sink fin group 3 are staggered and separated, and the lower-row heat pipes 52 of the second heat sink fin group 2 and the lower-row heat pipes 52 of the third heat sink fin group 3 are staggered and separated. This enables a high heat conduction efficiency between the heat pipes and each heat sink fin group, and at the same time makes the structure of the overall radiator more compact, effectively saving the installation space.

[0025] As shown in the attached Figure 1 and the attached Figure 2As shown, the number of the second group of heat dissipation tubes is set to one group. The second group of heat dissipation tubes is the middle row of heat dissipation tubes 53. The middle row of heat dissipation tubes 53 is arranged through the middle part of the substrate 4 and is located between the upper row of heat dissipation tubes 51 and the lower row of heat dissipation tubes 52. The middle row of heat dissipation tubes 53 can effectively improve the heat absorption efficiency of the substrate 4, and the heat absorbed by the substrate 4 from the light source is quickly transferred to each heat dissipation fin group 2.

[0026] As shown in the Figure 1 attachment, all the first group of heat dissipation tubes are perpendicular to the second heat dissipation fin group 2 and the third heat dissipation fin group 3. The second group of heat dissipation tubes are parallel or perpendicular to the second heat dissipation fin group 2 and the third heat dissipation fin group 3, making the structure of the radiator more compact.

[0027] As shown in the Figure 2 and Figure 3 attachment, the substrate 4 is mainly composed of an upper fixing plate 41 and a lower fixing plate 42. A plurality of first grooves 411 with downward openings are spacedly arranged on the lower end surface of the upper fixing plate 41. Second grooves 421 with upward openings and corresponding to the first grooves 411 one by one are arranged on the upper end surface of the lower fixing plate 42. The first grooves 411 and the second grooves 421 jointly form a first fixing groove 400 corresponding to and adapted to the middle row of heat dissipation tubes 53. The first fixing groove 400 can fully contact the surface of the middle row of heat dissipation tubes 53 while fixing the middle row of heat dissipation tubes 53, so as to increase the heat conduction efficiency.

[0028] As shown in the Figure 2 and Figure 3 attachment, a plurality of third grooves 412 with upward openings are spacedly arranged on the upper end surface of the upper fixing plate 41. The upper row of heat dissipation tubes 51 is adaptively installed in the third grooves 412. A flat surface 510 is arranged on the part of the upper row of heat dissipation tubes 51 adapted to the third grooves 412, and the flat surface 510 is flush with the upper end surface of the upper fixing plate 41. The flat surface 510 and the upper end surface of the upper fixing plate 41 jointly form an installation plane for installing the light source. The installation plane can fully contact the lamp board of the light source, thereby effectively increasing the heat conduction efficiency. Compared with the prior art in which an installation board is also required to be attached to the substrate for installation and then the lamp board is attached to the installation board, the installation plane on this product directly contacts the lamp board of the light source, that is, the upper row of heat dissipation tubes 51 and the upper end surface of the substrate 4 directly contact the lamp board surface of the light source, so that it can be closer to the heat source and further improve the heat dissipation efficiency of the light source.

[0029] As shown in the Figure 2 and Figure 3As shown, a plurality of fourth grooves 422 with downward openings are spaced apart on the upper end surface of the lower fixing plate 42. A fifth groove 100 corresponding to each of the fourth grooves 422 is provided at the top of the first heat sink fin group 1. The fourth groove 422 and the fifth groove 100 jointly form a second fixing groove 200 corresponding and adapted to the lower row of heat dissipation tubes 52, which not only fixes the lower row of heat dissipation tubes 52 but also enables the lower row of heat dissipation tubes 52 to be in surface contact with the substrate 4 and the first heat sink fin group 1 respectively.

[0030] As shown in the attached Figure 1 figure, heat dissipation fans 6 are provided at the bottoms of the first heat sink fin group 1, the second heat sink fin group 2, and the third heat sink fin group 3; the heat dissipation fans 6 can drive cold air flow to exchange heat with the surfaces of the heat sink fin groups, further increasing the heat dissipation efficiency.

[0031] The present invention also provides a stage light including the high-efficiency radiator, which includes a light source assembly 7 and the radiator, and the light source assembly 7 is fixedly installed at the top end of the substrate 4 of the radiator.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various equivalent changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalent scope.
