Description

Technical Field

[0001] The invention belongs to the technical field of industrial control computers, and specifically designs an industrial control computer with high-efficiency heat dissipation. Background Art

[0002] Generally speaking, industrial computers are computers designed specifically for industrial sites. The industrial site environment is generally more complex, and factories operate continuously, requiring equipment to run continuously for a long time. Industrial computers will generate heat during operation. If this heat cannot be dissipated quickly, it will increase the temperature of the industrial computer, affecting its normal operation or even failure, thereby affecting the normal operation of factory equipment and production lines.

[0003] In the prior art, for example, the Chinese utility model patent document with authorization announcement number CN214504301U discloses a heat dissipation type wall-mounted industrial computer, which accelerates the air flow inside the box through a heat dissipation fan, thereby improving its heat dissipation effect. However, excessively fast air flow will inhale external dust, which will cause a large amount of dust to accumulate inside the device after running for a period of time. The dust will adhere to the inside of the chassis, affecting the heat dissipation effect.

[0004] Another example is the Chinese utility model patent document with authorization announcement number CN214225849U, which discloses a multi-point efficient heat dissipation silent industrial control chassis, which transfers the heat of the central processing unit to the heat dissipation structure of the industrial control chassis through three heat pipes. In addition to retaining the heat dissipation of the traditional technology heat sink, the heat is transferred to the surface of the industrial control chassis for multi-point efficient heat dissipation. However, when the heat is dissipated to the outside of the chassis, if the heat around the chassis is not dissipated in time, the temperature difference between the air around the chassis and the inside of the chassis is small, the heat transfer efficiency is reduced, and the heat dissipation effect is affected.

[0005] Therefore, it is necessary to design an industrial computer with good sealing performance, which can dissipate the heat from the outside in time and ensure the heat dissipation effect to solve the current technical problems. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides an industrial computer with good sealing performance, capable of dissipating the outer heat in time and ensuring the heat dissipation effect and high efficiency heat dissipation.

[0007] The technical solution of the present invention is: an industrial computer with efficient heat dissipation, comprising a shell, a plurality of circular heat sinks with increasing diameters are arranged on the top of the shell from the inside to the outside, a rotating shaft is rotatably arranged at a position on the top of the shell corresponding to the center of the circular heat sink, a driving device for driving the rotating shaft to rotate is arranged inside the shell, a rotating rod is arranged at the upper end of the rotating shaft, and a guide plate is tilted downward at a position on the rotating rod corresponding to the gap between two adjacent heat sinks.

[0008] The driving device comprises a driving gear and a motor for driving the driving gear to rotate. The rotating shaft is rotatably connected to the inner bottom of the shell. The lower end of the rotating shaft is equipped with a driven gear, and the driven gear is meshed with the driving gear.

[0009] The heat sink passes through the top of the shell, and a second coil is provided on one end of the heat sink located inside the shell. First coils are provided on both side walls inside the shell, and the first coil is connected in series with the second coil. Cooling liquid is provided inside the first coil and the second coil, and a circulation mechanism is transmission-connected on the rotating shaft to drive the cooling liquid inside the first coil and the second coil to circulate.

[0010] The circulation mechanism has an isolation shell, and a compression air bag and a cam matching the compression air bag are arranged inside the isolation shell. The cam is sleeved on the outer side of the rotating shaft. The end of the first coil is connected to the air outlet of the compression air bag through a first one-way valve, and the end of the second coil is connected to the air inlet of the compression air bag through a second one-way valve.

[0011] A movable plate is arranged between the cam and the compression airbag, and both ends of the movable plate are slidably connected with the isolation shell.

[0012] Slide blocks are arranged at both ends of the movable plate, and the isolation shell is provided with a clearance groove corresponding to the movement track of the slide block. Supports are arranged at both ends of the clearance groove, and guide rods slidably connected to the slide block are fixedly arranged on the support.

[0013] 7. The industrial computer with high-efficiency heat dissipation according to claim 4, characterized in that a buffer air bag is connected in series between the second coil and the second one-way valve.

[0014] The compression airbag and the buffer airbag are both rubber airbags.

[0015] The cam has two symmetrical protrusions, and there is a smooth transition between the two protrusions.

[0016] A protective net is arranged on the top of the heat sink outside the rotating rod.

[0017] The beneficial effects of the present invention are as follows: the heat inside the shell of the industrial computer with efficient heat dissipation in the present invention is diffused outwardly through the heat sink, so as to achieve the purpose of heat dissipation. The heat sink can increase the heat dissipation area and improve the heat dissipation effect. Moreover, the driving device drives the rotating shaft to rotate the rotating rod, and the rotating rod drives the guide plate to rotate between the heat sinks. The air with higher temperature between the heat sinks can be guided upward through the moving guide plate inclined surface, so that the air temperature between the heat sinks is maintained at a lower state. The temperature difference between the heat sink and the ambient temperature outside the heat sink is large, the heat conversion efficiency is high, and the heat dissipation efficiency of the heat sink is maintained well. In addition, the overall shell is tightly closed and has a certain dustproof effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to further improve the heat dissipation effect, the heat sink 2 passes through the top of the shell 1, and a second coil 11 is arranged on one end of the heat sink 2 located inside the shell 1. The second coil 11 passes through the heat sink 2 and is coiled in a serpentine shape. First coils 10 are arranged on both side walls inside the shell 1. The first coil 10 is coiled in a serpentine shape on the side walls of the shell 1. The first coil 10 is connected in series with the second coil 11. Cooling liquid is arranged inside the first coil 10 and the second coil 11. The cooling liquid can be selected from liquids such as water. A circulation mechanism for driving the cooling liquid inside the first coil 10 and the second coil 11 to circulate is connected to the rotating shaft 4; the first coil 10 is used to absorb heat inside the shell 1.

[0028] As a specific embodiment of the circulation mechanism, the circulation mechanism has an isolation shell 18, and a compressed air bag 14 and a cam 12 matched with the compressed air bag 14 are arranged inside the isolation shell 18. The cam 12 is sleeved on the outer side of the rotating shaft 4. The end of the first coil 10 is connected to the air outlet of the compressed air bag 14 through a first one-way valve 16, and the end of the second coil 11 is connected to the air inlet of the compressed air bag 14 through a second one-way valve 17, wherein the liquid in the first one-way valve 16 flows unidirectionally from the compressed air bag 14 to the first coil 10, and the liquid in the second one-way valve 17 flows from the second coil 11 to the first coil 10. 1 to the compressed air bag 14 unidirectional flow, the rotating shaft 4 drives the cam 12 to rotate, the cam 12 acts on the compressed air bag 14 to squeeze and release the compressed air bag 14, after the compressed air bag is squeezed, the volume of the compressed air bag 14 is reduced, and the coolant inside it can be squeezed into the first coil 10, and after the release, the compressed air bag 14 recovers, and its volume becomes larger, and the coolant in the second coil 11 can be sucked into it, thereby the compressed air bag 14 is continuously driven by the cam 12 to be squeezed or released, and the coolant inside the first coil 10 and the second coil 11 can be driven to circulate continuously.

When the compression airbag 14 is squeezed, the buffer airbag 15 expands, and when the compression airbag 14 recovers, the buffer airbag 15 contracts; more specifically, the compression airbag and the buffer airbag are both rubber airbags.
