DETAILED DESCRIPTION OF EMBODIMENTS

(4) In the present embodiment, a finned heat-exchange system, with schematic diagrams as shown in FIGS. 1 and 2, comprises a heat dissipation chamber, a fin 1, an air guide element 2 and a base 4. The heat dissipation chamber is isolated from the outside, and both the fin 1 and the air guide element 2 are connected to the base 4; and the air guide element 2 and the fin 1 are in communication with the heat dissipation chamber through the base 4 to dissipate heat from the inside of the heat dissipation chamber. The outside is the natural environment.

(5) The finned heat-exchange system can be installed inside a device to be cooled. Particularly, in the present embodiment, the device to be cooled is a stage light, and the finned heat-exchange system is installed in an inner cavity 12 of the light. When a light-emitting component of the stage light generates heat, the heat will enter the air guide element 2 from the heat dissipation chamber and will be dissipated by means of the fin 1, and during heat dissipation, the heat dissipation chamber and the air guide element 2 can form a circulation channel to increase the heat exchange area and improve the heat exchange efficiency. The finned heat-exchange system thus can extend the service life of the stage light.

(6) According to the present embodiment, the air guide element 2 is composed of several air guide pipes. In this embodiment, the air guide pipes are embedded into the fin 1, and two ends of each of the air guide pipes are in communication with the heat dissipation chamber through the base 4. The adjacent air guide pipes are evenly disposed at equal intervals. With such arrangement, heat can be evenly transferred into the air guide pipe, thereby ensuring better dissipation of heat.

(7) In addition, the heat dissipation chamber comprises an air inlet cavity 6 and an air outlet cavity 5. With such arrangement, when heat enters the air guide element 2 from the air inlet cavity 6, part of the heat will be dissipated to the outside via the fin 1, the other part of the heat will continue to be transferred into the air outlet cavity 5, and the heat flowing out of the air outlet cavity 5 can enter the air inlet cavity 6 again, thereby achieving the circulation of heat. Moreover, the arrangement of the air inlet cavity 6 and the air outlet cavity 5 can increase the length of the circulation channel, which facilitates better circulation and dissipation of heat to the outside.

(8) Two ends of each of the air guide pipes are respectively arranged inside the air inlet cavity 6 and the air outlet cavity 5. Such arrangement can ensure better transfer and dissipation of heat.

(9) In addition, one end, at the air inlet cavity 6 and/or the air outlet cavity 5, of each of the air guide pipes can extend to any position outside the air inlet cavity 6 and/or the air outlet cavity 5. In this embodiment, all the air guide pipes are different in length extending out of the air inlet cavity 6 and/or the air outlet cavity 5. Such arrangement can achieve better transfer and dissipation of heat and bring a significant heat dissipation effect.

(10) Each of the air guide pipes is provided with an auxiliary air guide device at an extension end at the air inlet cavity 6 and/or the air outlet cavity 5. With such arrangement, the heat generated by a light-emitting element can be smoothly transferred into the air inlet cavity 6 and the air outlet cavity 5, which is convenient for the circulation of heat in the circulation channel, thereby improving the heat dissipation effect. The auxiliary air guide device is an air guide plate.

(11) In addition, the heat-exchange system further comprises a first air-driving device 7 provided at any position in an air channel extension path of the air inlet cavity 6 or the air outlet cavity 5. The configuration of the first air-driving device 7 can enhance air convection inside the heat dissipation chamber. In this embodiment, the first air-driving device 7 is arranged at any position in the air channel extension path of the air inlet cavity 6.

(12) The heat-exchange system further comprises a second air-driving device 9 for enhancing the efficiency of heat exchange between the fin 1 and the outside. In this embodiment, the second air-driving device 9 has an air direction parallel to the fin 1. With such arrangement, the heat-exchange system can achieve better heat dissipation effect.
