Description

Technical Field

[0001] This invention relates to the field of industrial host technology, specifically to a fanless heat exchange type silent industrial host. Background Technology

[0002] An industrial host computer, also known as an industrial control computer, is a computer designed specifically for industrial environments. It uses a closed aluminum alloy casing instead of a fan for passive heat dissipation, which not only achieves a quiet operation but also prevents dust and impurities from being sucked into the chassis. This avoids problems such as short circuits, corrosion, and reduced heat dissipation performance caused by dust accumulation. It also has advantages such as high reliability and anti-interference capabilities, and is therefore widely used in automation, power, transportation and other fields. For example, the patent disclosed in the prior art with publication number "CN223815528U" is entitled "A Fanless Industrial Main Unit." It discloses that the heat generated by the main unit is transferred to multiple sets of fins through an outer casing. These fins expand the heat dissipation area of ​​the main unit. The coolant inside the heat dissipation pipes absorbs heat from the outer casing and fins and is then transferred to the radiator for cooling. The cooled coolant then flows back to the heat dissipation pipes, repeating this process. The combination of multiple fins and coiled heat dissipation pipes ensures a large contact area between the coolant and the main unit. Furthermore, by replacing the traditional heat dissipation chamber with coiled heat dissipation pipes, the required amount of coolant is effectively reduced while improving the cooling and replacement efficiency. The outer casing is fitted over the main unit. On the outside, the heat pipes are coiled between multiple sets of fins. For example, the patent titled "A Fanless Industrial Host" disclosed in the prior art with the publication number "CN206479918U" discloses a base plate, a cover plate, a front panel, and a rear panel. The base plate, cover plate, front panel, and rear panel together form the internal space of the chassis. The motherboard is installed in the internal space. Several protruding fin-shaped heat sinks are formed on the outer surface of the cover plate. The fin-shaped heat sinks are arranged in parallel and integrally formed on the outer surface of the cover plate. The whole structure is a flat block structure. The longitudinal direction of its cross-section is perpendicular to the outer surface of the cover plate. This structure greatly increases the heat dissipation area and improves the heat dissipation performance. The cover plate can be made of aluminum alloy, which takes into account heat dissipation performance, structural strength, and weight.

[0003] In the aforementioned existing fanless heat exchange type silent industrial host, a relatively static, high-temperature hot air layer forms on the surface of the heating element. Moreover, the industrial host mainly relies on static natural convection and thermal radiation for heat dissipation. This results in a slow airflow speed inside the industrial host, which in turn leads to slow heat dissipation and cooling efficiency, making it impossible for the industrial host to be used continuously for a long time. Therefore, we propose a fanless heat exchange type silent industrial host to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide a fanless heat exchange type silent industrial host to solve the problem mentioned in the background art. In the current fanless heat exchange type silent industrial host, a relatively static, high-temperature hot air layer forms on the surface of the heating element. Moreover, the industrial host mainly relies on static natural convection and thermal radiation for heat dissipation. This results in a slow airflow speed inside the industrial host, which in turn leads to slow heat dissipation and cooling efficiency, making it impossible for the industrial host to be used continuously for a long time.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fanless heat exchange type silent industrial host, including a base plate and a front panel installed on the upper front side of the base plate, and a rear panel connected to the upper rear side of the base plate, and a chassis body connected to the base plate between the rear panel and the front panel. The bottom surface of the base plate is connected to a mounting bracket through a mounting assembly, and a first storage tube is installed on the upper right side of the base plate, and a pushing assembly is provided inside the first storage tube. A sliding frame is slidably connected to the inner right side of the chassis body, and an agitator is connected to the upper left end of the sliding frame. An agitator plate for agitating airflow is fixed above the agitator.

[0006] Preferably, the rear panel, front panel, bottom plate and chassis body are sealed together. The outer sides of the front panel and bottom plate are integrally formed with heat dissipation fins. The front panel and bottom plate are made of aluminum alloy. The front panel has a USB interface, a COM interface and a power switch installed from left to right. The rear panel also has a COM interface installed inside. The motherboard is installed on the top of the bottom plate.

[0007] Preferably, the mounting assembly includes screws, and mounting brackets are symmetrically mounted on the bottom surface of the base plate by the screws, with the mounting brackets arranged in an "L" shape.

[0008] Preferably, the pushing component includes a first piston assembly fitted and installed inside the first storage tube, and a push block is fixed above the first piston assembly, with both the upper and lower sides of the push block being inclined surfaces, and argon gas is injected into the first storage tube located below the first piston assembly.

[0009] Preferably, the right end of the sliding frame is T-shaped, and a connecting spring is installed in the groove opened on the right inner wall of the chassis body. The rear end of the connecting spring is connected to the right end of the sliding frame. Furthermore, a push block is provided below the sliding frame, and the sliding frame forms a back-to-back reciprocating sliding structure through the push block.

[0010] Preferably, a manual telescopic rod is fixed above the left end of the sliding frame, and an agitator is fixed above the manual telescopic rod. A return spring is nested on the outer side of the upper part of the manual telescopic rod, and a protrusion is installed in the corresponding housing body on the upper right side of the agitator. The protrusion is semi-circular, and the lowest point of the protrusion is lower than the highest point of the agitator. The agitator forms a reciprocating lifting structure through the protrusion.

[0011] Preferably, the agitator is arranged in a "T" shape.

[0012] Preferably, the mounting assembly includes a guide rod mounted above the bottom of the mounting bracket, with the outer side of the guide rod slidably connected to the outer side of the base plate, and a buffer spring nested below the outer side of the guide rod, and a buffer rubber pad mounted on the mounting bracket located directly below the base plate.

[0013] Preferably, a second storage tube is fixedly installed through the interior of both the left and right sides of the base plate, and a second piston assembly is attached to the interior of the second storage tube. The bottom end of the second piston assembly is connected to the mounting bracket, and argon gas is injected into the second storage tube located above the second piston assembly.

[0014] Preferably, the base plate forms a lifting structure via a second storage tube.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This fanless heat exchange type silent industrial host can automatically agitate the hot air layer inside the industrial host with its stirring plate, thereby increasing the airflow speed inside the industrial host, facilitating good contact between the hot air and the chassis body, avoiding local heat accumulation, and thus improving the heat dissipation and cooling efficiency of the industrial host. This allows the industrial host to be used continuously for a long time and can meet different usage needs. The specific details are as follows: The rising of the push block, whose upper and lower surfaces are both inclined, can push the sliding frame to move backward first. Later, through the storage of the connecting spring, it can automatically drive the sliding frame, the stirring frame, and the stirring plate to move back and forth for a certain period of time. This allows the stirring plate to automatically stir the hot air layer inside the industrial host, increasing the airflow speed inside the industrial host, making it easier for the hot air to come into good contact with the chassis body, avoiding local heat accumulation, and thus improving the heat dissipation and cooling efficiency of the industrial host. This allows the industrial host to be used continuously for a long time and can meet different usage needs. Furthermore, by using the first storage tube and the first piston assembly together, a certain amount of argon gas is injected into the first storage tube. Therefore, when the temperature inside the industrial host rises, the argon gas expands when heated and automatically pushes the first piston assembly to rise. This allows the first piston assembly to drive the push block to rise without the need for an additional power source, saving energy and reducing production costs. The argon gas inside the second storage tube expands when heated, automatically pushing the second piston assembly downwards. This causes the base plate to move upwards, thus increasing the distance between the base plate and the mounting area. This, in turn, improves the airflow around the chassis and enhances the heat dissipation efficiency of the heat sink fins on the outside of the base plate. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-10 The present invention provides the following technical solution: Example 1: The fanless heat exchanger-type silent industrial host in this example can automatically agitate the hot air layer inside the industrial host, increasing the airflow speed inside the industrial host and facilitating good contact between the hot air and the chassis body 3, avoiding localized heat accumulation. See attached diagram for the specific structure. Figures 1-6 As shown, there is a base plate 1 and a front panel 2 installed on its front side. A rear panel 8 is connected to the rear side of the base plate 1. A chassis body 3 is connected to the base plate 1 between the rear panel 8 and the front panel 2. A mounting bracket 7 is connected to the bottom surface of the base plate 1 through a mounting assembly. A first storage tube 14 is installed on the upper right side of the base plate 1. A pushing assembly is provided inside the first storage tube 14. A sliding bracket 11 is slidably connected to the inner wall of the right side of the chassis body 3. An agitator 12 is connected to the upper left end of the sliding bracket 11. An agitator plate 13 for agitating airflow is fixed above the agitator 12. The rear panel 8, the front panel 2, the base plate 1 and the chassis body 3 are sealed together. Heat dissipation fins are integrally formed on the outer sides of the front panel 2 and the base plate 1. The front panel 2 and the base plate 1 are made of aluminum alloy. A USB interface 6, a COM interface 4 and a power switch 5 are installed inside the front panel 2 from left to right. A COM interface 4 is also installed inside the rear panel 8. A motherboard 9 is installed on the top of the base plate 1.

[0020] The mounting components include screws, and mounting brackets 7 are symmetrically mounted on the bottom surface of the base plate 1 via screws. The mounting brackets 7 are arranged in an "L" shape. The pushing components include a first piston assembly 141 that fits into the first storage tube 14, and a push block 142 is fixed above the first piston assembly 141. The upper and lower sides of the push block 142 are inclined surfaces. Argon gas is injected into the first storage tube 14 located below the first piston assembly 141. The right end of the sliding bracket 11 is arranged in a "T" shape, and a connecting spring 15 is installed in a groove opened on the inner wall of the right side of the chassis body 3. The rear end of the connecting spring 15 is connected to the sliding bracket 11. The right end of 1 is connected, and a push block 142 is provided below the sliding frame 11. The sliding frame 11 forms a back-to-back reciprocating sliding structure through the push block 142. A manual telescopic rod 16 is fixed above the left end of the sliding frame 11, and an agitator 12 is fixed above the manual telescopic rod 16. A return spring 161 is nested on the outer side of the upper part of the manual telescopic rod 16. A protrusion 10 is installed in the corresponding chassis body 3 on the upper right side of the agitator 12. The protrusion 10 is semi-circular, and the lowest point of the protrusion 10 is lower than the highest point of the agitator 12. The agitator 12 forms a reciprocating lifting structure through the protrusion 10.

[0021] First, move the entire industrial host to the installation area. Then, install the mounting bracket 7 in the installation area using screws. Next, insert the corresponding wiring harnesses into the industrial interfaces such as COM port 4 and USB port 6 on the front panel 2 and rear panel 8. Then, press the power switch 5, and the entire industrial host can be used. During use, the motherboard 9 and other heat-generating components will generate a certain amount of heat. This heat can be dissipated through the integrated heat sink fins on the outside of the chassis 3. Since there is no fan installed inside the industrial host, it can achieve a silent operation. If the heat continues to increase, a certain amount of argon gas injected into the first storage tube 14 will expand upon heating, automatically pushing the first piston assembly 141 upward. The first piston assembly 141 will drive the push block 142 upward. Since the upper and lower surfaces of the push block 142 are both inclined, the push block 142 will automatically push the sliding bracket 11 backward when it rises. When the sliding frame 11 moves, the right end of the sliding frame 11 slides in the groove on the inner wall of the right side of the chassis body 3. The connecting spring 15 is pulled and stored. The left end of the sliding frame 11 drives the stirring frame 12 and the stirring plate 13 to move backward together through the manual telescopic rod 16. When the push block 142 rises and separates from the sliding frame 11, the stored force of the connecting spring 15 can automatically drive the sliding frame 11, the stirring frame 12 and the stirring plate 13 to move back and forth for a certain period of time. This allows the stirring plate 13 to automatically stir the hot air layer inside the industrial host, increase the airflow speed inside the industrial host, and facilitate the hot air to contact the surface of the aluminum alloy chassis body 3 well, avoiding local heat accumulation. This improves the heat dissipation and cooling efficiency of the industrial host, allowing the industrial host to be used continuously for a long time, meeting different usage needs. Moreover, it can drive the push block 142 to rise without an additional power source, saving energy and reducing production and manufacturing costs.

[0022] When the stirring frame 12 and the stirring plate 13 move back and forth in a reciprocating motion within a certain period of time, when the stirring frame 12 contacts the protrusion 10, the semi-circular protrusion 10 automatically applies a downward pushing force to the stirring frame 12. At this time, the manual telescopic rod 16 retracts, and the return spring 161 stores energy. When the stirring frame 12 separates from the protrusion 10, as shown above, the stored energy of the return spring 161 automatically drives the manual telescopic rod 16 to stretch and return to its original position, so that the manual telescopic rod 16 drives the stirring frame 12 to return to its original position. Therefore, the stirring frame 12 and the stirring plate 13 move back and forth in a reciprocating motion while moving up and down in a reciprocating motion, further increasing the stirring range and stirring amplitude of the stirring plate 13 on the hot air inside the industrial host, and further increasing the airflow speed inside the industrial host.

[0023] Example 2: Based on Example 1, the fanless heat exchanger-type silent industrial host in this example discloses a different structure for the agitator plate 13, which can further improve the agitation efficiency and agitation amplitude of the agitator plate 13. The specific structure is shown in the attached diagram. Figure 7 As shown, the stirring plate 13 is arranged in a "T" shape.

[0024] The stirring plate 13 in this application is T-shaped, which allows the stirring plate 13 to further increase the stirring range and stirring amplitude when it moves up and down, thereby further increasing the airflow speed inside the industrial host.

[0025] Example 3: This example of a fanless heat exchanger-type silent industrial host, based on Example 1, discloses another mounting component that allows the base plate 1 to move upwards. This increases the spacing between the mounting areas of the base plate 1, thereby improving the airflow around the chassis and facilitating better heat dissipation efficiency of the heat sink fins on the outside of the chassis body 3 and the base plate 1. The specific structure is shown in the attached diagram. Figures 8-10 As shown, the mounting assembly includes a guide rod 17 mounted above the bottom of the mounting bracket 7, with the outer side of the guide rod 17 slidably connected to the outer side of the base plate 1. A buffer spring 171 is nested and connected to the lower outer side of the guide rod 17. A buffer rubber pad 71 is mounted on the mounting bracket 7 located directly below the base plate 1. Second storage tubes 18 are fixedly inserted through the interior of both sides of the base plate 1. A second piston assembly 181 is fitted inside the second storage tube 18. The bottom end of the second piston assembly 181 is connected to the mounting bracket 7. Argon gas is injected into the second storage tube 18 located above the second piston assembly 181. The base plate 1 forms a lifting structure through the second storage tube 18.

[0026] First, move the entire industrial host to the installation area. Then, install the mounting bracket 7 in the installation area using screws. Next, insert the corresponding wiring harnesses into the industrial interfaces such as the COM port 4 and USB port 6 on the front panel 2 and rear panel 8. Then, press the power switch 5, and the entire industrial host can be used. During the use of the industrial host, the motherboard 9 and other heat-generating components will generate a certain amount of heat. At this time, a certain amount of argon gas injected into the second storage tube 18 expands when heated. Since the second piston assembly 181 is fixed, the second storage tube 18 causes the base plate 1 and the chassis body 3 to move upward together, increasing the distance between the base plate 1 and the installation area. This improves the airflow around the chassis body 3 and the heat dissipation efficiency of the heat sink fins on the outside of the base plate 1.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
