It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0047] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0048] like Figures 1 to 6As shown, it is a structural diagram of a heat dissipation assembly for a cabinet provided by an embodiment of the present invention, comprising an outer shell 1, an inner shell 2, an air-cooling heat dissipation mechanism 100, an air intake system 200, a dust removal mechanism 300, an atomization cooling mechanism 400 and an anti-water accumulation mechanism 500. The outer shell 1 and the inner shell 2 are connected by a cylinder 3. The air-cooling heat dissipation mechanism 100 is provided with multiple groups.

The air-cooling heat dissipation mechanism 100 is driven by an independently arranged motor to dissipate heat for the cabinet components placed in the inner shell 2; the air intake system 200 is arranged outside the outer shell 1, and the air intake system 200 is communicated with the space between the outer shell 1 and the inner shell 2; The dust removal mechanism 300 is installed in the side frame 9 in the air intake system 200, and the side frame 9 has an air intake fan built in, so that the external air can be sucked into the interior through the holes on the side frame 9, and sent to the surface of the heating element along the air intake system 200 for heat dissipation; the atomizing cooling mechanism 400 is arranged on the outer shell 1, and the air passing through the air intake system 200 and entering between the outer shell 1 and the inner shell 2 is sprayed for cooling; the anti-water accumulation mechanism 500 is arranged at the bottom end of the longitudinal axis 5 in the air-cooled heat dissipation mechanism 100, and the anti-water accumulation mechanism 500 is also communicated with the atomizing cooling mechanism 400, and in the process of rotating with the longitudinal axis 5, it squeezes the moisture in the air and sends the water flow into the atomizing cooling mechanism 400.

[0049] In one embodiment of the present invention, the built-in air intake fan guides external air into the side frame 9, and dust is removed by the dust removal mechanism 300. After the dust-removed air enters the outer shell 1 and the inner shell 2, it is cooled by the arranged air intake system 200. After cooling, when the air-cooling heat dissipation mechanism 100 is working, it moves along the surface of the heat-generating components inside the cabinet to take away the heat dissipated by the components during operation. The air-cooling heat dissipation mechanism 100 also squeezes the accumulated water through the arranged anti-water accumulation mechanism 500 to prevent water from accumulating at the bottom of the outer shell 1, thereby keeping the working environment in a dry state.

[0050] like Figure 1 As shown, as a preferred embodiment of the present invention, the air-cooling heat dissipation mechanism 100 includes a longitudinal shaft 5, a fan blade 6, a sprocket 7 and a chain 8;

[0052] Among them, sprockets 7 are installed on the multiple longitudinal shafts 5 located in the same horizontal plane, and the sprockets 7 are connected through chains 8 for transmission.

At the same time, the connection method of the chain 8 is changed accordingly, so that multiple longitudinal shafts 5 can rotate synchronously to ensure that the longitudinal shafts 5 and the fan blades 6 are evenly distributed on the outside of the heating element inside the cabinet, and the heat of the heating element is sent out when the longitudinal shaft 5 and the fan blades 6 rotate.

[0056] A plurality of air guide holes 13 are provided, and the air guide holes 13 are evenly distributed at the bottom of the inner shell 2 .

[0057] In one embodiment of the present invention, when the air intake fan is working, air enters the side frame 9, and moves upward along the air guide 10 and the outer tube 11 in sequence, passes through the air cavity 12 and enters the space between the outer shell 1 and the inner shell 2, and gradually turns to move upward along the surface of the heating element when moving downward through the air guide hole 13, and finally is discharged from the outer shell 1.

[0058] like Figure 1 and Figure 2 As shown, as another preferred embodiment of the present invention, the dust removal mechanism 300 includes a scraper 14, an electrostatic dust suction rod 15, an insulating portion 16 and a driving screw 17;

[0059] The electrostatic dust suction rod 15 is longitudinally mounted on the inner wall of the side frame 9, and an insulating portion 16 is provided at the end of the electrostatic dust suction rod 15;

[0060] The electrostatic dust collecting rod 15 is slidably mounted with a scraper 14, which is driven by a driving screw 17 independently arranged on the side frame 9 to scrape off the dust attached to the electrostatic dust collecting rod 15, thereby preventing the dust from entering the interior from the source.

[0061] In one embodiment of the present invention, dust entering the side frame 9 falls on the electrostatic dust suction rod 15. When the external motor drives the driving screw 17 to rotate, the scraper 14 can be pushed to slide along the surface of the electrostatic dust suction rod 15 to scrape off the attached dust, and when passing through the insulating part 16, the dust is released from adsorption and sent out.

The scraper 14 is also connected to the elastic member installed on the inner side of the side frame 9. Such an arrangement can also realize the scraper 14 sliding along the electrostatic dust suction rod 15 to complete the reciprocating dust removal work.

[0063] like Figure 1 and Figure 3 As shown, as another preferred embodiment of the present invention, the atomizing cooling mechanism 400 includes an annular storage frame 18, a liquid infusion tube 19, a shunt tube 20 and an atomizing nozzle 21;

[0064] The annular storage frame 18 is horizontally installed on the outside of the housing 1. The top of the annular storage frame 18 is connected with a liquid infusion tube 19. The liquid infusion tube 19 is communicated with a shunt tube 20 installed in the housing 1. The bottom of the shunt tube 20 is correspondingly installed with an atomizing nozzle 21.

[0065] The liquid infusion pipe 19 is supplied with liquid by a pump body installed in the annular storage frame 18, and the liquid infusion pipe 19 is located inside the outer tube 11, so as to cool down the air flowing in the outer tube 11 when delivering the coolant.

[0066] In one example of the present invention, the annular storage frame 18 can be equipped with semiconductor cooling fins as needed to cool the incoming water flow, and the water flow moves upward along the infusion pipe 19 under the action of the pump body, and finally sprays out from the atomizing nozzle 21 after passing through the shunt pipe 20, so as to perform secondary spray cooling on the air after conduction cooling.

[0067] like Figure 1 and Figure 4 As shown in FIG. 1 , as another preferred embodiment of the present invention, the anti-water accumulation mechanism 500 includes a movable plate 22, a special-shaped groove 23, a vertical rod 24 and a movable rod 25;

[0068] The movable disk 22, the vertical rod 24 and the movable rod 25 are arranged between the outer shell 1 and the inner shell 2, wherein the movable disk 22 is fixedly connected to the longitudinal axis 5, the vertical rod 24 is slidably connected to the outer shell 1, and the movable rod 25 is fixedly mounted on the vertical rod 24;

[0069] One end of the movable rod 25 is slidably connected to the housing 1, and the other end of the movable rod 25 is slidably connected to the special-shaped groove 23 provided on the movable disk 22, so as to push the vertical rod 24 and the movable rod 25 to move in the height direction when the movable disk 22 rotates.

[0070] In an embodiment of the present invention, the longitudinal shaft 5 drives the movable disk 22 at the corresponding position to rotate synchronously when rotating, and the movable rod 25 is lifted and lowered along the housing 1 under the action of the special-shaped groove 23, and drives the vertical rod 24 to lift and lower synchronously therewith.

[0071] like Figure 1 and Figure 5 As shown, as another preferred embodiment of the present invention, the anti-water accumulation mechanism 500 further includes a breathable baffle 26, a water-absorbing cotton 27, an elastic sleeve 28, a reflux pipe 29 and a triangular groove 30;

[0072] The breathable baffle 26 is fixedly installed between the outer shell 1 and the inner shell 2, and the bottom of the breathable baffle 26 is fixedly connected to the absorbent cotton 27;

[0073] The elastic sleeve 28 is fixedly connected to the top of the vertical rod 24. A leakage hole is opened on the upper surface of the elastic sleeve 28. The leakage hole is communicated with the inner cavity of the elastic sleeve 28. The inner cavity is communicated with the annular storage frame 18 through the return pipe 29.

[0074] The movable end of the elastic sleeve 28 is provided with evenly distributed air holes, and a triangular groove 30 is opened on the outer side of the inner shell 2 to facilitate squeezing and draining when the elastic sleeve 28 is separated from the triangular groove 30;

[0075] A second absorbent cotton is installed between the outer shell 1 and the inner shell 2 at the bottom of the first absorbent cotton 27 .

[0076] In one embodiment of the present invention, the humidified air moves downward through the breathable baffle 26 and the absorbent cotton 27, and the absorbent cotton 27 absorbs moisture. When the dried cold air is in the triangular groove 30 at the movable end of the elastic sleeve 28, the air moves downward along the air holes. When the elastic sleeve 28 is pushed away from the triangular groove 30 by the vertical rod 24, the movable end of the elastic sleeve 28 retracts into the interior, and the elastic sleeve 28 squeezes the absorbent cotton 27. The squeezed water flows along the leakage holes and the inner cavity set on the elastic sleeve 28, and is finally introduced into the annular storage frame 18 through the reflux pipe 29.

[0077] The present invention also discloses a heat dissipation device for a cabinet, the heat dissipation device comprising a heat dissipation component, a fixed plate 4 and a movable plate 31;

[0078] The fixed plate 4 is installed at the middle of the top of the housing 1, and a movable plate 31 is slidably installed on the fixed plate 4;

[0079] The fixed plate 4 is provided with a hole 1, and the movable plate 31 is provided with a hole 2. When the movable plate 31 is pulled, the relative positions of the hole 1 and the hole 2 are adjusted to achieve the purpose of enclosing the space, so that the cabinet can dissipate heat and ventilate when working, and prevent dust from entering the interior when not working.

[0080] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0081] In summary, in actual use, the movable plate 31 is pulled to make the hole 1 and the hole 2 communicate with each other, and the built-in air intake fan works to guide the external air into the side frame 9. The dust entering the side frame 9 falls on the electrostatic dust suction rod 15. When the external motor drives the driving screw 17 to rotate, the scraper 14 can be pushed to slide along the surface of the electrostatic dust suction rod 15 to scrape off the attached dust, and when passing through the insulating part 16, the dust is separated from the adsorption and sent out. The air moves upward along the air guide pipe 10 and the outer pipe 11 in turn, and is cooled for the first time by the infusion pipe 19. The air passes through the air cavity 12 and enters the outer shell 1 and the inner shell 2, at this time, the coolant moves upward along the infusion tube 19 under the action of the pump body, and after passing through the shunt tube 20, it is finally sprayed out from the atomizing nozzle 21, and the air after conduction cooling is subjected to secondary spray cooling. The humidified air moves downward through the breathable baffle 26 and the absorbent cotton 1 27, and the absorbent cotton 1 27 and the absorbent cotton 2 absorb moisture. When the air moves downward through the air guide hole 13, it gradually turns to move upward along the surface of the heating element. The longitudinal shaft 5 drives the sprocket 7 at the corresponding position to rotate, and drives the sprocket 7 and the longitudinal shaft 5 at the remaining positions to rotate through the arranged chain 8. When the shaft 5 and the fan blade 6 rotate, the heat of the heating element is sent out through the hole 1 and the hole 2. When the longitudinal shaft 5 rotates, it also drives the movable disk 22 at the corresponding position to rotate synchronously. The movable rod 25 rises and falls along the shell 1 under the action of the special-shaped groove 23, and drives the vertical rod 24 to rise and fall synchronously. After the elastic sleeve 28 is pushed by the vertical rod 24 to break away from the triangular groove 30, the movable end of the elastic sleeve 28 retracts inside, and the elastic sleeve 28 squeezes the absorbent cotton 27. The squeezed water flows along the leakage holes and the inner cavity set on the elastic sleeve 28, and is finally introduced into the annular storage frame 18 through the return pipe 29; The present application has the characteristics of a wide coverage area, and can dissipate heat from multiple sides to the heat-generating components inside the cabinet, so as to greatly improve the efficiency of heat dissipation; the heat dissipation is relatively uniform, and there is no problem of concentrated cooling position, which can avoid the occurrence of uneven heat dissipation caused by changes in the trajectory of cold air; it also prevents dust from entering the cabinet from the source of air intake, and automatically realizes the adsorption, scraping and collection of dust, thereby improving the safety of heat dissipation while avoiding the dust inside the cabinet from being raised; it can realize the internal circulation of coolant, effectively improve the utilization efficiency of coolant, and avoid water accumulation inside, which affects the working state of components.

[0082] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
