[0002] The computer case generally exchanges and dissipates heat inside and outside through a plurality of built-in heat dissipation fans and heat dissipation holes on the shell, such as a computer heat dissipation case disclosed in Chinese Patent Specification No. CN108008786A, but since there are many electrical elements inside, the requirement for dust and foreign matter prevention is high, so the heat dissipation holes are arranged at the top and bottom, the heat dissipation holes at the top are covered with a magnetic dustproof mesh, and the bottom is also provided with heat dissipation holes, the case is raised by the foot, a gap is formed between the bottom and the ground, and then a circulating heat dissipation channel is realized.

[0003] However, since the bottom is close to the ground, the air flow performance is poor, and since the heat dissipation holes at the top are covered with a mesh, the exhaust of hot air is inhibited to a certain extent, so that the overall heat dissipation effect is poor, and the electrical elements are often continuously operated in a high-temperature environment, which affects the running speed and stability of the computer. When overheating occurs, the rotation speed of the heat dissipation fan is generally increased to speed up heat dissipation, such as the computer case disclosed in Chinese Patent Specification No. CN107329536A, but the built-in heat dissipation fan inhales and exhausts hot air inside the case when blowing and dissipating heat, that is, the air flow only circulates inside, so that a large temperature difference cannot be established when the hot air flow blows to the surface of the electrical elements, the heat exchange effect is limited, and the overall heat dissipation performance is poor.

DETAILED DESCRIPTION

[0029] The two embodiments of the application will be described in detail below with reference to the accompanying drawings.

[0030] First embodiment:

[0031] Figures 1-2 It is shown that a computer case with a multi-directional heat dissipation air duct includes a case body 1 with a temperature sensor installed inside, which can monitor the temperature inside the case in real time, and then different heat dissipation modes can be taken. The heat dissipation top net 21 is fixedly embedded on the upper end of the case body 1, and the shielding dense net 2 is magnetically attracted above the heat dissipation top net 21. The bottom foot 101 is fixedly connected to each corner of the bottom of the case body 1, and the heat dissipation bottom net 102 is also fixedly embedded on the bottom of the case body 1, which can realize synchronous ventilation and heat dissipation of the top and bottom.

[0032] As Figure 1 and Figure 3, the front and rear side plates of the cabinet body 1 are double-layered, the double-layered side plate comprises an inner partition back plate 32 located in the cabinet body 1 and an outer cover plate 31 located outside the cabinet body 1, the outer cover plate 31 and the inner partition back plate 32 are connected with the cabinet body 1 through bolts, the outer cover plate 31 completely covers the inner partition back plate 32, and the sandwich gap is formed between the outer cover plate 31 and the inner partition back plate 32, two groups of inner embedded air ducts in triangular distribution are arranged on the outer cover plate 31, two air suction fans 33 corresponding to the two groups of inner embedded air ducts are installed on the inner partition back plate 32, and air holes not corresponding to the inner embedded air ducts are reserved on the inner partition back plate 32, when the temperature in the cabinet body 1 is relatively low, part of the hot air in the cabinet body 1 can spread and gather into the sandwich gap through the air holes reserved on the inner partition back plate 32, and then is discharged outwards through the inner embedded air ducts, so that synchronous heat dissipation in four directions of up, down, left and right of the cabinet body 1 is realized, when the temperature in the cabinet body 1 is too high, the air suction fan 33 can be controlled to start, the air suction fan 33 can suck low-temperature air outside through the inner embedded air ducts and deliver the low-temperature air into the cabinet body 1, so that the cabinet body 1 presents a micro-positive pressure state, at this time, the original hot air in the cabinet body 1 is extruded and discharged outwards, thereby realizing active external circulation of the air in and outside the cabinet body 1, and then the air is discharged outwards along the holes, gaps and the like on the cabinet body 1, compared with the internal self-circulation of the built-in heat dissipation fan in the prior art, the exchange of internal and external heat and heat dissipation are greatly accelerated.

[0033] It is worth noting that the starting temperature critical point of the air suction fan 33 can be set according to actual needs in specific implementation, and the temperature is set as the threshold value of the temperature sensor.

[0034] As Figures 4-5 , the inner embedded air duct comprises a plurality of heat dissipation holes drilled on the outer cover plate 31 and a side passing strip 302 fixedly connected to the inner wall of the heat dissipation hole, the side passing strip 302 is located in the sandwich gap, and the side passing strip 302 does not contact the inner partition back plate 32, the side passing strip 302 is U-shaped, and only the two ends of the U-shaped side passing strip 302 are fixed to the inner wall of the heat dissipation hole, and the remaining edge of the U-shaped side passing strip 302 and the edge of the mouth of the heat dissipation hole form an air passing gap, so that the mouth of the air passing gap is parallel to the outer cover plate 31 instead of being perpendicular to the outer cover plate 31, so that when air is inhaled, the middle part of the side passing strip 302 can play a certain interception and blocking role on the air, so that the dust carried in the gas can be intercepted to a certain extent, and the probability of entering the cabinet body 1 is reduced, and the inner partition back plate 32 opposite to the side passing strip 302 can again intercept the dust outside, so as to protect the internal electrical elements from being affected by the dust, effectively protect the electrical elements in the cabinet, and reduce the influence on the operation stability of the computer.

[0035] As Figures 4-5The end surface of the outer baffle plate 31 close to the inner partition back plate 32 is fixedly connected with two air disturbance units, the two air disturbance units are respectively located on the sides of the two groups of embedded air ducts away from each other, and the openings of the two groups of air disturbance units respectively face the two groups of embedded air ducts. The air disturbance unit comprises a semicircular arc strip 41 fixedly connected to the back surface of the outer baffle plate 31, a plurality of air disturbance pipes 42 fixedly connected to one end of the semicircular arc strip 41 facing the side through strip 302, and a rectangular long hole 301 opened in the outer baffle plate 31, the rectangular long hole 301 is opposite to the semicircular arc strip 41, the middle part of the semicircular arc strip 41 is in contact with the inner partition back plate 32, so that the interlayer gap is relatively stable, the stable heat dissipation on the side surface is maintained, and the rectangular long hole 301, the semicircular arc strip 41 and the air disturbance pipe 42 are sequentially communicated, so that the air disturbance unit is communicated inside and outside, and when not working, it can also bear a part of the heat exchange between the inside and outside air.

[0036] The air disturbance pipe 42 is provided with a disturbance assembly, the disturbance assembly comprises an electromagnetic ring one 51 and an electromagnetic ring two 53 fixedly connected outside the air disturbance pipe 42, a magnetic ring 52 located between the electromagnetic ring one 51 and the electromagnetic ring two 53, and a driven air pushing piece 61 and a passive air pushing piece 62 located in the air disturbance pipe 42, the driven air pushing piece 61 and the passive air pushing piece 62 are both made of ferromagnetic material, and both of them generate magnetic attraction with the magnetic ring 52, the inner slide groove 501 is opened in the inner wall of the air disturbance pipe 42, and the passive air pushing piece 62 is matched with the inner slide groove 501, such as Figure 7 When normal heat dissipation, the air disturbance unit can be started, first, the electromagnetic ring one 51 can be controlled to pass through the forward current, so that the corresponding magnetic ring 52 generates magnetic repulsion, at the same time, the electromagnetic ring two 53 is controlled to pass through the reverse current, so that the corresponding magnetic ring 52 generates magnetic attraction, the two work at the same time, so that the magnetic ring 52 moves to the side of the electromagnetic ring two 53, under the action of magnetic attraction, it moves together with the driven air pushing piece 61, in this process, the driven air pushing piece 61 gradually approaches the passive air pushing piece 62 and moves together with the passive air pushing piece 62, at this time, the two coincide, the pores on the surfaces of the two are blocked by each other, so that the air is difficult to pass through, and then the air in the air disturbance pipe 42 can be pushed out from the inside to the plurality of side through strips 302, so that the air flow at the side through strip 302 is disturbed to a certain extent, the speed of the hot air across the air gap and the external exhaust is accelerated, so as to accelerate the heat exchange between the hot air in the cabinet body 1 and the low temperature air outside;

[0037] Then, the current of the electromagnetic ring one 51 and the electromagnetic ring two 53 can be controlled to be reversed, so that the magnetic force changes, and then the electromagnetic ring one 51 generates magnetic attraction to the corresponding magnetic ring 52, and the electromagnetic ring two 53 generates magnetic repulsion to the corresponding magnetic ring 52, so that the magnetic ring 52 can carry the driven air pushing piece 61 and the passive air pushing piece 62 to move reversely, when moving to the limit position of the inner slide groove 501, the driven air pushing piece 61 and the passive air pushing piece 62 are separated; then the above process is repeatedly, so as to realize the circulating disturbance of the hot air at the side through strip 302.

[0038] AsFigure 6 The diameter of the active air pushing fin 61 is smaller than that of the passive air pushing fin 62, the inner sliding groove 501 is located between the electromagnetic ring one 51 and the electromagnetic ring two 53, the electromagnetic ring two 53 is flush with the inner wall of the inner sliding groove 501 away from the semicircular arc strip 41, the electromagnetic ring one 51 is misaligned with the inner sliding groove 501, the passive air pushing fin 62 is bored with a side hole 602 at the center, the active air pushing fin 61 is bored with a plurality of central holes 601 arranged in a ring array, and the central holes 601 and the side hole 602 are not coincident with each other, so that when the active air pushing fin 61 and the passive air pushing fin 62 are coincident with each other, the central holes 601 and the side hole 602 are in a blocking state, at this time, the air flow is facilitated to be pushed, and the disturbance effect of the hot air at the opposite side through strip 302 is better, when the active air pushing fin 61 and the passive air pushing fin 62 are separated from each other, the central holes 601 and the side hole 602 are not blocked, at this time, the air flows on both sides of the two, so that the air disturbance pipe 42, the semicircular arc strip 41 and the rectangular long hole 301 can also bear part of the effect of exchanging the inside and outside air.

[0039] By arranging the side plate with the interlayer gap, when the temperature in the case is low, part of the heat can be collected in the interlayer gap, and cooperating with the air disturbance unit, the air flow speed in the embedded air duct can be accelerated, the air flow is turbulent, the hot air is not easy to stay in the interlayer gap for a long time, and the external exhaust of the hot air at this place is effectively accelerated, when the temperature in the case is high, the air suction fan 33 can directly absorb the low-temperature air outside, so that the inside of the case body 1 is in a state of micro-positive pressure, thereby effectively accelerating the external exhaust of the internal hot air from the shielding mesh 2 and the heat dissipation bottom mesh 102, effectively realizing the internal and external circulation of the air flow, significantly accelerating the heat exchange effect, compared with the prior art, the heat dissipation speed can be greatly accelerated, the accumulation of heat in the case is reduced, and the influence on the stability of the computer operation is reduced.

[0040] The second embodiment:

[0041] On the basis of the first embodiment, the present embodiment adds a shaking support 7 and makes adaptive improvement to the outer shutter 31, and the rest is the same as the first embodiment.

[0042] Figure 8 It is shown that the outer shutter 31 includes an outer rectangular frame, a shaking plate 312 located in the outer rectangular frame, and a connection layer 311 fixedly connected between the outer rectangular frame and the shaking plate 312, the connection layer 311 is a elastic structure, the embedded air duct is located on the shaking plate 312, the semicircular arc strip 41 is located on the outer rectangular frame, a plurality of shaking supports 7 are fixedly connected between the shaking plate 312 and the inner partition back plate 32, the shaking support 7 includes a fixed piece 71, a movable piece 73, and a high-rebound interlayer 72 fixedly connected between the fixed piece 71 and the movable piece 73, the fixed piece 71 and the movable piece 73 are fixedly connected with the inner partition back plate 32 and the shaking plate 312 respectively, the fixed piece 71 is an electromagnetic structure, and the movable piece 73 is a ferromagnetic structure.

[0043] As Figures 9-10 , in the normal heat dissipation, while the air disturbance unit disturbs the hot air at the two groups of embedded air ducts, the multiple fixed pieces 71 can be controlled to be powered on synchronously, thereby attracting the multiple moving pieces 73 to move towards the inner partition back plate 32, thereby driving the whole shaking plate 312 to move, in this process, on the one hand, the hot air can be disturbed in a large area, on the other hand, part of the hot air in it can be forced to pass through the air gap and be discharged, in the process of continuous reciprocating movement, the heat dissipation is further accelerated.

[0044] In combination with the current actual demand, the above-mentioned embodiments adopted by the present application are not limited to the scope, various changes made within the knowledge range of the skilled person in the art without departing from the concept of the present application still fall within the protection scope of the present application.
