Description

Technical Field

[0001] The present invention relates to the technical field of stage light heat dissipation, and particularly to a novel radiator and a stage light thereof. Background Art

[0002] The cooling fans of the radiator of the stage light are respectively installed at the front end and the rear end of the radiator. Generally, the cooling fan at the front end drives cold air to blow towards each heat dissipation channel of the radiator. After the cold air exchanges heat with the radiator, the cooling fan at the rear end extracts the hot air generated after heat exchange in each heat dissipation channel out of the body, that is, one end of the radiator is for blowing air and the other end is for sucking air; this will cause uneven heat dissipation of the radiator. It can be understood that the temperature of the end of the radiator where the blowing fan is installed is lower than the temperature of the end of the radiator where the sucking fan is installed. Furthermore, it causes the heat absorption of each part of the radiator facing the light source to be unequal, and the radiator cannot be fully utilized to dissipate heat from the light source, resulting in a low heat dissipation efficiency of the radiator of the light source. Therefore, the unevenness of the radiator heat dissipation easily affects the normal operation of the light emitting source assembly. Summary of the Invention

[0023] 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.

[0024] As shown in the atta Figure 1 ched draw Figure 5As shown in the figure, the present invention creates a new type of radiator and a stage light using this new type of radiator. Among them, the new type of radiator includes a first heat dissipation fin group 1, a heat conduction plate 2, and several first heat dissipation tubes 3. The first heat dissipation fin group 1 is in thermal conduction with the heat conduction plate 2 through several of the first heat dissipation tubes 3. The first heat dissipation fin group 1 includes several first heat dissipation fins 11 distributed at intervals. A first heat dissipation channel 10 is formed between adjacent first heat dissipation fins 11. At least one side of the front and rear sides of the first heat dissipation fin group 1 is provided with a wind driving member 4. A wind guiding wall 12 extending towards the left and right ends is provided in each first heat dissipation channel 10. The wind guiding wall 12 is used to guide the air volume in the first heat dissipation channel 10 to blow out towards the left and right sides of the first heat dissipation fin group 1. Preferably, the wind driving members 4 are provided on both the front and rear sides of the first heat dissipation fin group 1. Two of the wind guiding walls 12 are symmetrically arranged on each first heat dissipation fin 11. The wind direction of the wind driving member 4 is directly opposite to the wind guiding wall 12 one by one.

[0025] Specifically, the wind driving member 4 is a cooling fan. The cooling fans on the front and rear sides are both in a blowing state, that is, the cooling fan drives the outside cold air to blow into the first heat dissipation channel 10 for heat exchange. After heat exchange, since the wind guiding wall 12 extends towards the left and right ends of the radiator, the hot air can be dissipated from the left and right ends of the radiator under the drive of the cooling fan and the guidance of the wind guiding wall 12. Based on this, this new type of radiator can obtain better heat dissipation uniformity and high-efficiency heat dissipation, thus effectively ensuring the normal operation of the light source.

[0026] As shown in the attached Figure 4 and attached Figure 5 figure, a through hole 100 is formed in the middle of each first heat dissipation fin 11. The inner edge of the through hole 100 is folded to form the wind guiding wall 12. The wind guiding walls 12 of adjacent first heat dissipation fins 11 are stacked on each other. Specifically, the height of the folded wind guiding wall 12 is 2 - 5 mm, and the wind guiding wall 12 extends to near the left and right ends of the first heat dissipation fin 11. Further, the wind guiding wall 12 is at a right angle to the first heat dissipation fin 11.

[0027] In this embodiment, the air guide wall 12 is composed of an inclined section 121, an arc section 122, and a straight section 123. There is a central symmetry line A that is symmetric about the front and back sides between the two air guide walls 12 on the first heat sink 11. The two ends of the inclined section 121 are respectively connected to one end of the arc section 122, and the other ends of the arc section 122 are both connected to the straight section 123. The distance between the inclined section 121 and the central symmetry line A gradually decreases from the center of the inclined section 121 along the left and right ends. The distance between the arc section 122 and the central symmetry line A gradually decreases along the direction of its respective outer end (left / right end). The distance between the straight section 123 and the central symmetry line A remains unchanged along the direction of its respective outer end (left / right end), so that the cross-sectional area of the first heat dissipation channel 10 gradually increases from the middle to both ends, which can effectively slow down the flow rate of cold air, increase the heat exchange duration, ensure the sufficiency of heat exchange, and thus improve the efficiency of heat exchange.

[0028] As shown in the attached Figure 4 figure, the first heat dissipation fin group 1 is provided with a receiving groove 101 formed by aligning the through holes 100 of each first heat sink 11. A light source assembly 5 located in the receiving groove 101 is fixedly arranged on the top of the heat conducting plate 2, making the installation of the light source assembly 5 on the radiator more compact. Therefore, under the condition of ensuring the effective length of the light path, the volume of the radiator can be optimized, and the volume of the stage light can be effectively reduced.

[0029] As shown in the attached Figure 2 and attached Figure 3 figure, the first heat dissipation tube 3 includes a first duct main body section 31 and first bending sections 32 respectively bent from both ends of the first duct main body section 31. First grooves are provided on both the top and bottom of the heat conducting plate 2. The first duct main body section 31 is correspondingly placed in the first grooves, and both of the first bending sections 32 pass through the first heat dissipation fin group 1, so that the heat generated when the light source assembly works is sequentially transferred to each first heat sink 11 through the heat conducting plate 2 and the first heat dissipation tube 3, thereby improving the heat dissipation efficiency of the radiator.

[0030] As shown in the attached Figure 3 figure, the radiator further includes a second heat dissipation fin group 6 arranged at the bottom of the heat conducting plate 2. The second heat dissipation fin group 6 includes a plurality of second heat sinks 61, and a second heat dissipation channel 62 is formed between adjacent second heat sinks 61. The air driving member 4 is also arranged at the bottom of the second heat dissipation fin group 6, and the air driving member 4 drives the air volume to blow out along both sides of the second heat dissipation channel 62. The second heat dissipation fin group 6 can further improve the heat dissipation efficiency of the radiator.

[0031] As shown in the attached Figure 6As shown, the second heat dissipation fin group 6 is provided with second grooves corresponding one by one to the first grooves at the bottom of the heat conduction plate 2. The first grooves and the second grooves together form a first slot 200 for inserting the first duct main section 31, facilitating the full contact between the first heat dissipation tube 3, the heat conduction plate 2, and the second heat dissipation fin group 6, and improving the heat transfer efficiency.

[0032] As shown in the Figure 6 drawing, the second heat dissipation fin group 6 is in heat conduction with the heat conduction plate 2 through a plurality of second heat dissipation tubes 7. The second heat dissipation tube 7 includes a second duct main section 71 and second bending sections 72 respectively bent from both ends of the second duct main section 71. The bottom of the heat conduction plate 2 is further provided with a plurality of third grooves, and the second heat dissipation fin group 6 is provided with fourth grooves corresponding one by one to the third grooves. The third grooves and the fourth grooves form a second slot 300 for inserting one of the second bending sections 72, and the other second bending section 72 is inserted into the second heat dissipation fin group 6, facilitating the full contact between the second heat dissipation tube 7, the heat conduction plate 2, and the second heat dissipation fin group 6, and further improving the heat transfer efficiency.

[0033] As shown in the Figure 2 drawing, an installation groove 60 is formed at the bottom of the second heat dissipation fin group 6, and the air driving member 4 is installed in the installation groove 60, making the structure of the radiator more compact, saving the installation space of the radiator, and making the stage light smaller in volume.
