As an embodiment of the present invention, as shown in fig. 5, fixing plates 22 are fixedly connected to both sides of the inner wall of the casing 1 near the vertical plate 19, the fixing plates 22 are connected to the communication rod 21, drainage grooves 23 are formed in both sides of the inner bottom of the casing 1, both ends of the drainage grooves 23 are connected to the drainage holes 3, and the drainage holes 3 penetrate the casing 1 and communicate with the outside.

The combiner is installed outdoors and can often encounter humid air, the breathable sponge 20 can absorb the humid air around the heat dissipation holes 2 through the heat dissipation holes 2, when excessive moisture is absorbed, the water absorption effect of the breathable sponge 20 can be reduced, and meanwhile, the air permeability of the breathable sponge 20 is also influenced.

The using method comprises the following steps: when the circuit module 7 in the combiner of the invention is in load operation, a large amount of heat is generated, the heat conducting block 8 conducts a part of heat on the surface of the circuit module 7, the other part of heat on the surface of the circuit module 7 is conducted into the air in the combiner, then the heat on the heat conducting block 8 is conducted out by the heat conducting plate 9, when the heat on the heat conducting plate 9 is conducted onto the memory alloy spring 18, the memory alloy spring 18 is heated and stretched to be straightened because the temperature of the memory alloy spring 18 is higher than the set temperature, so that the vertical plate 19 is pushed to move, and the air-permeable sponge 20 fixed on the vertical plate 19 is also driven to move, because a plurality of groups of vertical plates 19 are fixed on the connecting rod 21, the vertical plates 19 of other heat dissipation hole groups are driven to move when one group of vertical plates 19 is pushed, and the movement of the vertical plates 19 can push the air-permeable sponge 20 to not shield the heat dissipation holes 2 any more, at this time, the hot air inside the combiner is discharged to the outside of the combiner through the heat dissipation holes 2, and the cold air enters the combiner to cool the circuit module 7, so that when the circuit module 7 inside the combiner generates an excessive temperature, the heat dissipation holes 2 are automatically opened to circulate the cold air and the cold air, thereby preventing the circuit module 7 from being burnt out due to the excessive temperature, after the temperature inside the combiner is reduced, the temperature on the surface of the memory alloy spring 18 is also reduced, meanwhile, the temperature on the surface of the memory alloy spring 18 is lower than the preset temperature, the memory alloy spring 18 contracts and bends, simultaneously, the vertical plate 19, the breathable sponge 20 and the connecting rod 21 are driven to move reversely, finally, the breathable sponge 20 covers the heat dissipation holes 2, and the wind shields 27 installed on the two sides of the shell 1 can avoid the problem that the heat dissipation holes 2 are opened, part of rainwater enters the combiner, the invention realizes that the heat produced by the circuit module 7 is discharged through the air-permeable sponge 20 and the heat dissipation holes 2 when in normal operation, but the air convection speed is low, the work of the circuit module 7 is not influenced, the problem of short circuit of the circuit module 7 caused by rainwater entering the combiner through the heat dissipation holes 2 in rainy days is also avoided, when the memory alloy spring 18 pushes the vertical plate 19 to move, the fixing rod 25 is driven to move, and meanwhile, the movement of the fixing rod 25 drives the clamping strips 5 and the sealing plates 4 to move, because a plurality of groups of clamping strips 5 and sealing plates 4 are fixedly connected to the connecting rod 17, when one set of the clamping strips 5 and the sealing plate 4 moves, the connecting rods 17 drive the plurality of sets of the clamping strips 5 and the sealing plate 4 to move, therefore, the sealing plate 4 does not shield the heat exhaust port 16 any more, and a part of hot air in the combiner is exhausted from the heat exhaust port 16, so that the heat dissipation effect of the combiner is further improved.

According to the invention, when the circuit module 7 conducts heat to the heat conducting block 8, the heat on the heat conducting block 8 is conducted to the first rotating wheel 10, the first rotating wheel 10 is made of a heat-conducting material, so that the first rotating wheel 10 easily conducts the heat to the memory alloy wire 12 when absorbing the heat on the heat conducting block 8, the temperature of the surface of the memory alloy wire 12 on the first rotating wheel 10 is higher than the set temperature after absorbing the heat, then the memory alloy wire 12 is straightened, but the memory alloy wire 12 is restrained by the first rotating wheel 10, because the memory alloy wire 12 on the heated part only drives the first rotating wheel 10 to rotate when wanting to be straightened, when the heated memory alloy wire 12 runs to the second rotating wheel 11, because the heat conduction far away from the first rotating wheel 10 disappears a part, the memory alloy wire 12 on the second rotating wheel 11 with the temperature reduced can bend and cling to the second rotating wheel 11, the memory alloy silk 12 of first runner 10 end straightens, the memory alloy silk 12 of second runner 11 end is crooked, it can drive first runner 10 and second runner 11 emergence rotation to realize whole process, the rotation of second runner 11 can drive flabellum 13 and rotate, flabellum 13 rotates and can flabellate the hot-air in the combiner and discharge from heat extraction port 16, the inside circulation of air speed of combiner is improved, thereby further improve the radiating effect of combiner, utilize the metallic characteristic of memory alloy silk 12, drive first runner 10, thereby second runner 11 rotates and drives flabellum 13 and rotate, realize intelligent control, the radiating problem of fan has been avoided adopting.
