Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1-7 As shown: One embodiment of the present invention is:

[0031] like Figure 1 and 2 As shown, a converter with good heat dissipation effect includes a converter body 1, one end of the converter body 1 is electrically connected to a connection socket 2 connected to the outside, the converter body 1 includes a shell, a plurality of retractable heat dissipation fin assemblies 3 are arranged in parallel on the top of the shell, a lifting drive assembly 4 is installed in the inner cavity of the shell, one end of the lifting drive assembly 4 passes through the shell and is connected to the heat dissipation fin assembly 3 and drives the heat dissipation fin assembly 3 to retract;

[0032] The heat dissipation fin assembly 3 includes a first heat dissipation fin 31 and a second heat dissipation fin 32 which are hollow inside. The second heat dissipation fin 32 is sleeved on the outer wall of the first heat dissipation fin 31 and is slidably connected to the first heat dissipation fin 31. The outer walls on opposite sides of the second heat dissipation fin 32 are connected to a plurality of transversely arranged third heat dissipation fins 33 along the height direction. The opposite side walls of the first heat dissipation fin 31 are symmetrically slidably connected to fourth heat dissipation fins 34. One end of the fourth heat dissipation fin 34 is inserted into the inner cavity of the first heat dissipation fin 31 and is provided with a plurality of limit blocks 35. The fourth heat dissipation fin 34 and the limit block 35 are both hollow structures inside, and an opening is provided at one end of the two limit blocks 35 which are close to each other. A spring 36 is provided between the limit block 35 and the inner wall of the first heat dissipation fin 31. A limit rod 37 which cooperates with the limit block 35 is connected to the top of the inner cavity of the second heat dissipation fin 32. The limit block 35 and the limit rod 37 are both provided with mutually cooperating inclined surfaces.

[0033] like Figure 2 As shown, in the present embodiment, in order to enable the heat to be better transferred to the inside of the first heat dissipation fin, each first heat dissipation fin 31 is connected to the top of the shell, and the heat can flow into the first heat dissipation fin through the connecting port between the shell and the first heat dissipation fin, and then flow into the second heat dissipation fin, the third heat dissipation fin and the fourth heat dissipation fin, and the air can contact each heat dissipation fin when flowing, so that the heat can be taken away faster.

[0034] like Figure 7 As shown, in this embodiment, the limit rod 37 includes a first limit rod and a second limit rod connected to each other, and the first limit rod and the second limit rod are transitioned by an inclined surface, and the width of the second limit rod is greater than the width of the first limit rod, wherein in the contracted state, the limit block of each layer abuts against the first limit rod to ensure the fixation of the position of the fourth heat sink fin, and in the extended state, the limit block abuts against the second limit rod.

[0035] like Figure 6 As shown, in the present embodiment, in order to ensure better heat transfer between the second heat sink fin and the first heat sink fin, a plurality of heat conducting strips 38 are provided on the opposite side walls of the first heat sink fin 31, and the heat conducting strips 38 are provided with notches which cooperate with the fourth heat sink fin 34, and the inner wall of the second heat sink fin 32 is provided with a heat conducting groove which cooperates with the heat conducting strip 38, wherein the mutual cooperation between the heat conducting strip and the heat conducting groove can not only ensure the stable sliding between the second heat sink fin and the first heat sink fin, but also enable the heat to be conducted through the heat conducting strip and the heat conducting groove.

[0036] like Figure 4 and 5As shown, in this embodiment, in order to be able to adjust the heat dissipation capacity of the heat dissipation fin assembly in real time according to the temperature inside the shell, the lifting drive assembly 4 includes a mercury sealing groove 41 installed on the side wall of the inner cavity of the shell, a piston block 42 is slidably connected between the inner walls of the mercury sealing groove 41, a sliding column 43 is fixedly connected to one side of the piston block 42, and mercury is filled between the other side of the piston block 42 and the inner wall of the mercury sealing groove 41, one end of the sliding column 43 passes through the mercury sealing groove 41 and is connected to a gear condition 44, and screws 45 are symmetrically rotatably connected to the two opposite sides of the top of the shell, one end of the screw 45 is inserted into the inner cavity of the shell and is installed with a rotating gear 46 meshing with the gear condition 44, and the outer wall of one end of the screw 45 located outside the shell is threadedly connected with A threaded sleeve 47, a connecting strip 48 is fixedly connected to the top of the threaded sleeve 47, and the connecting strip 48 spans over each second heat sink fin 32 and is fixedly connected to the top of the second heat sink fin 32, and the connecting strip 48 is connected to the second heat sink fin 32 by bolts, wherein the mercury in the mercury sealing groove expands due to the increase in the temperature inside the shell, and pushes the piston block and the sliding column to slide, so that the gear condition at the end of the sliding column slides and drives the rotating gear to rotate, thereby driving the screw to rotate, so that the threaded sleeve and the connecting strip slide upward, thereby driving the second heat sink fin to slide upward, increasing the heat dissipation area of ​​the heat sink fin assembly, improving the heat dissipation effect, and finally achieving the heat dissipation effect of the heat sink fins that can be adjusted in real time when the temperature rises.

[0037] like Figure 5 As shown, in this embodiment, in order to improve the heat conduction capacity of the mercury sealing groove, a heat conducting sheet 49 is provided at the bottom of the mercury sealing groove 41 .

[0038] like Figure 4As shown, in this embodiment, in order to enable the converter to issue an alarm in time when the temperature inside the shell continues to rise when the heat dissipation fin assembly has been extended to the maximum area, the gear condition 44 includes a transverse connecting rod 441 connected to the sliding column 43, and the two opposite ends of the side of the transverse connecting rod 441 away from the sliding column 43 are fixed with sliding rods 442, and the same side of the two sliding rods 442 is provided with a gear group 443 that meshes with the rotating gear 46, and the gear group 443 is arranged at one end of the sliding rod 442 away from the transverse connecting rod 441 and a spacing is set between the transverse connecting rod 441, and the inner wall of the shell is provided with a push switch 5 that cooperates with a group of sliding rods 442, and the push switch Switch 5 is electrically connected to an external alarm, wherein in the early stage of the internal temperature rise of the shell, the sliding column pushes the sliding rod and the gear group and the rotating gear to engage, driving the second heat sink fin to rise, and after the second heat sink fin rises to the highest position, the gear group and the rotating gear are disengaged, and at this time when the internal temperature of the shell continues to rise, the sliding column continues to push the sliding rod to slide, and at this time, the end of the sliding rod without the gear group is in contact with the rotating gear, thereby not causing the second heat sink fin to continue to rise, and at the same time, when the internal temperature continues to rise to a certain temperature, the end of a group of sliding rods can contact the push switch and press the push switch to make the external alarm sound an alarm, reminding that the internal temperature of the shell is too high.

[0039] like Figure 3 and 4As shown, in the present embodiment, in order to be able to clean the surface of the second heat dissipation fins and prevent dust from adhering to the second heat dissipation fins and affecting the heat dissipation effect of the second heat dissipation fins, the outer walls of the two screws 45 are fixedly connected with sprockets 410, and the sprockets 410 are located between the threaded sleeve 47 and the shell, and a chain 411 is connected between the two sprockets 410, and a fixed block 412 is fixedly connected to the outer wall of one side of the chain 411, and the fixed block 412 is slidably connected to the chain 411 on the other side, and a telescopic rod 413 is fixedly connected to the top of the fixed block 412, and a sliding bar 414 spanning the top of the second heat dissipation fin 32 is fixedly connected to the top of the telescopic rod 413, and a rubber scraper 415 that cooperates with the second heat dissipation fin 32 and the third heat dissipation fin 33 is fixedly connected to the bottom of the sliding bar 414, and the rubber scraper 415 that cooperates with the second heat dissipation fin 32 and the third heat dissipation fin 33 is fixedly connected to the bottom of the sliding bar 414. 15 is provided with bristles, wherein since the gear groups on the two sliding rods are arranged on the same side, the two sliding rods can respectively drive the two rotating gears and the screw rods to rotate in the same direction, thereby driving the sprocket and the chain to rotate, so as to drive the fixed block, the telescopic rod, the sliding bar and the rubber scraper to slide, so that when the second heat sink fin rises, the rubber scraper can also be driven to clean the surfaces of the second heat sink fin and the third heat sink fin, and the second heat sink fin rises to a certain height, the rubber scraper slides a corresponding distance, and when the second heat sink fin slides to the highest position, the rubber scraper slides from the position of one screw rod to the position of another screw rod, thereby cleaning the second heat sink fin and the second heat sink fin within the range, and the setting of the telescopic rod can enable the rubber scraper to adapt to the extension and retraction of the second heat sink fin.

[0040] like Figure 4 and 5 As shown, in this embodiment, in order to prevent deformation of the chain caused by the extension and retraction of the telescopic rod, a T-shaped slide rail 416 that cooperates with the fixed block 412 is provided on the top of the shell, and a slide groove that cooperates with the T-shaped slide rail 416 is provided at the bottom of the fixed block 412. The T-shaped slide rail can limit the position of the fixed block, so that when the second heat dissipation fin drives the telescopic rod to extend and retract, it can also ensure that the fixed block will not generate a pulling force on the chain.

[0041] The specific working process of this embodiment is as follows:

[0042] When the converter is working, the converter body 1 is first installed and fixed, and then connected to the external device through the connection socket 2.

[0043] When the converter is working, the internal electrical components generate heat, and the heat is transferred to the mercury sealing groove 41 through the heat conducting sheet 49, so that the mercury expands due to the heat, thereby pushing the piston block 42 and the sliding column 43 to slide, so that the gear set 443 on the sliding rod 442 gradually contacts the rotating gear 46 and gradually drives the rotating gear 46 and the screw 45 to rotate, thereby driving the two threaded sleeves 47 and the connecting strip 48 to slide synchronously, and then driving the second heat dissipation fin 32 to rise, thereby increasing the contact area between the heat dissipation fin assembly 3 and the air, and improving the heat dissipation effect;

[0044] At the same time, when the second heat sink fin 32 slides upward, the limit rod 37 is simultaneously driven to slide upward, so that the inclined surface on the limit rod 37 gradually contacts the inclined surface on each layer of the limit block 35, thereby pushing the limit block 35 and the fourth heat sink fin 34 to slide, so that the fourth heat sink fin 34 passes through the first heat sink fin 31, so that the fourth heat sink fin 34 and the first heat sink fin 31, and the second heat sink fin 32 and the third heat sink fin 33 are arranged vertically to each other, so that turbulence can be generated when air flows through the heat sink fin assembly 3, thereby increasing the contact area and contact time between the air and the heat sink fin assembly 3, so that the heat on the heat sink fin assembly 3 can be better taken away, thereby improving the heat dissipation effect of the converter.

[0045] When the screw 45 rotates, the sprocket 410 and the chain 411 can be driven to rotate, thereby driving the fixed block 412 to slide along the T-shaped slide rail 416, thereby driving the rubber scraper 415 to clean the surface of the second cooling fin 32 and the third cooling fin 33, and when the second cooling fin 32 rises to the highest position, the rubber scraper 415 slides from the position of the sprocket 410 on one side to the position of the sprocket 410 on the other side, and cleans the second cooling fin 32 and the third cooling fin 33 of this section to prevent dust from adhering to the surface of the third cooling fin 33 and the second cooling fin 32 (because when the temperature is low, the first cooling fin 31 and the fourth cooling fin 34 are both inside the second cooling fin 32, so there is relatively little dust adhesion and no cleaning is required).

[0046] After the second heat sink 32 slides into place, when the temperature inside the converter body 1 continues to rise (the heat dissipation rate is lower than the heating rate), the mercury continues to expand and pushes the sliding column 43 and the sliding rod 442 to continue to slide, and because the gear set 443 has been out of contact with the rotating gear 46, it will no longer drive the screw 45 to rotate, and as the sliding rod 442 continues to slide and abuts against the push switch 5, the alarm electrically connected to the push switch 5 generates an alarm to remind the user that the temperature inside the converter body 1 is too high.

[0047] In the present invention, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0048] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
