Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of industrial electronic equipment, and specifically to an industrial computer. Background Art

[0002] At present, industrial computers are mainly divided into two categories according to the heat dissipation method, one is active heat dissipation and the other is passive heat dissipation. As the name suggests, active heat dissipation means that the industrial computer is equipped with heat dissipation components such as fans to drive air flow to dissipate heat, while passive heat dissipation achieves heat dissipation through heat exchange with the outside air through structures such as the shell and heat dissipation fins.

[0003] Since industrial computers need to work in industrial environments where there is a lot of dust, high requirements are placed on their dustproof performance. Among them, although passive cooling industrial computers have good dustproof capabilities, they are limited by their heat dissipation efficiency and cannot meet the heat dissipation needs of high-power industrial computers.

[0004] Active heat dissipation industrial computers inevitably need to have ventilation holes on the chassis for air circulation. However, the existing structure of simply setting dust screens at the ventilation holes cannot achieve a good dust-proof effect. Small particles of dust will still enter the chassis through the dust screen. Moreover, since most dust contains conductive substances such as carbon powder, it is easy to cause a short circuit in the internal circuit after entering the chassis, affecting the normal operation of the industrial computer.

[0050] Active heat dissipation industrial computers are equipped with air inlets and outlets. Air enters the machine body from the air inlet to take away heat and is discharged from the air outlet. During operation, the air inlet is under negative pressure and the outlet is under positive pressure. Therefore, many industrial computers only have simple dust prevention measures at the air inlet, such as covering with dustproof foam, but the air outlet is not treated. In this regard, the inventor of the present application found in practice that in a dusty working environment, on the one hand, the dustproof foam cannot achieve a good dustproof effect, and a certain amount of dust will still be sucked into the chassis through the dustproof foam. On the other hand, when the industrial computer is shut down or maintained, dust will fall into the chassis through the air outlet.

[0051] The dust that enters the chassis will inevitably have an impact on the industrial computer. In an industrial production environment, the dust generally contains conductive substances such as carbon powder, which can cause problems such as short circuits in the internal circuit structure of the industrial computer, seriously affecting the normal use of the industrial computer.

[0052] Based on this, the present application proposes an industrial computer, which adopts two dust-proof components for effective dust prevention at its air inlet. Specifically, the first dust-proof adopts an electrostatic filter, which can well adsorb the dust with charge on it, so as to prevent the charged dust from entering the inside of the chassis and affecting the operation of the circuit structure. The second dust-proof adopts a combination of dust-proof ventilation parts and dust-proof nets, in which a part of the dust passing through the first electrostatic filter will be deposited under the action of gravity after hitting the outer wall of the dust-proof ventilation parts, and the other part of the dust passing through the electrostatic filter and entering the dust-proof ventilation parts will be filtered out by the second dust-proof net, and finally only a very small amount may enter the inside of the chassis from the air inlet. Considering that the industrial computer is in working state for a long time, that is, the air outlet is in positive pressure state most of the time, it is difficult for dust to enter from the air outlet, so only one dust-proof component is set at the air outlet to prevent a large amount of dust from entering from the air outlet under the conditions of shutdown, maintenance, etc.

[0053] After testing and inspection, the industrial computer provided in the embodiment of the present application can achieve the IP5X dustproof level while installing a large graphics card to meet the heat dissipation requirements.

[0054] First see Figures 1 to 5 , Figure 1 The three-dimensional structure of the front side of the industrial computer is shown in FIG. Figure 2 The three-dimensional structure of the rear side of the industrial computer is shown in FIG. Figure 3 The internal structure of the industrial computer is shown in Figure 4 The two dust-proof structures on the front of the industrial computer are output. Figure 5 As shown in the figure, the industrial computer 100 provided in the embodiment of the present application includes: a body 110, a fan assembly 120, a first dustproof assembly 130, a second dustproof assembly 140 and a third dustproof assembly 150.

[0055] like Figure 5 and Figure 6 As shown in the figure, the fuselage 110 has a first panel 111 and a second panel 112 arranged opposite to each other, and the first panel 111 and the second panel 112 are respectively provided with an air inlet 1111 and an air outlet 1121. In the specific embodiment shown in the figure, the first panel 111 is the front panel of the fuselage 110, and the second panel 112 is the rear panel of the fuselage 110.

[0056] like Figure 3 As shown in FIG, the fan assembly 120 is disposed inside the body 110 and between the air inlet 1111 and the air outlet 1121. The fan assembly 120 is used to draw air from the air inlet 1111 and discharge it from the air outlet 1121 to achieve heat dissipation of the internal circuit of the body 110. Figure 3 In the specific embodiment shown, a fan assembly 120 is provided on the inner side of the air inlet 1111 and the inner side of the air outlet 1121. Of course, in some other embodiments, an exhaust fan may be provided only at the air inlet 1111, or an exhaust fan may be provided only at the air outlet 1121.

[0057] like Figure 6 As shown in FIG7 , the first dustproof assembly 130 is the second dustproof at the air inlet end, and includes a first dustproof net 131 and a dustproof ventilation piece 132, wherein the first dustproof net 131 covers the outside of the air inlet 1111, and the dustproof ventilation piece 132 is arranged on the side of the first dustproof net 131 away from the air inlet 1111. Specifically, the dustproof ventilation piece 132 can be a shutter or other ventilation structure with a partial outer cover, and the first dustproof net 131 can be a dustproof foam, a steel wire dustproof net, a fiber dustproof net, etc.

[0058] exist Figure 6 and Figure 7a In the specific embodiment shown, a fan assembly 120 is embedded at the air inlet 1111, and the fan assembly 120 includes a fan body 121 and a fan mounting frame 122. The fan body 121 is fixed to one side of the fan mounting frame 122. The dustproof ventilation member 132 includes a first mounting frame 1321 and window blades 1322. The first mounting frame 1321 covers the outer periphery of the first dustproof net 131, and the first mounting frame 1321 is detachably connected to the side of the fan mounting frame 122 away from the fan body 121 to clamp the first dustproof net 131 between the first mounting frame 1321 and the fan mounting frame 122, and the window blades 1322 are arranged in the internal space enclosed by the mounting frame 1321. The first dustproof net 131 covers the air duct on the fan mounting frame 122 to play a good dustproof role. Please further combine Figure 7bOn the back surface as shown, snap fasteners 1221 are provided on two opposite sides of the fan mounting bracket 122. During the assembly of the industrial control computer 100, the fan body 121, the fan mounting bracket 122, the first dust filter net 131, and the first mounting bracket 1321 can be first assembled to form an installation module 160 (as shown by the exploded module in Figure 6 ), and then the installation module is pushed into the air inlet 1111 from the outside. After being pushed in place, the raised edge 1222 of the fan mounting bracket 122 abuts against the outer wall at the air inlet 1111, and the snap fasteners 1221 are snap-connected to the inner wall at the air inlet 1111 to assemble and fix the installation module 160 on the fuselage 110. The whole process is convenient to operate and is beneficial to improving the assembly efficiency.

[0059] It can be understood that in some other embodiments, the first mounting bracket 1321 can also be detachably connected to the outer wall at the air inlet 1111, and the first dust filter net 131 is clamped between the outer wall at the air inlet 1111 and the first mounting bracket 1321.

[0060] The second dust prevention component 140 is the first dust prevention at the air inlet end. As shown by the exploded structure in Figure 6 , it includes a second dust filter net 141. The second dust filter net 141 is an electrostatic filter net and is arranged on the side of the dust prevention and ventilation member 132 away from the first dust filter net 131. The electrostatic filter net can adopt an existing electrostatic filter net capable of adsorbing charged dust.

[0061] As shown in Figure 2 and Figure 5 , the third dust prevention component 150 covers the outside of the air outlet 1121 and is responsible for dust prevention at the air outlet end. To ensure the reliability of the internal circuit operation of the fuselage 110, the third dust prevention component 150 can adopt an electrostatic filter net. Of course, it can also adopt a dust prevention foam, a steel wire dust filter net, a fiber dust filter net, etc. like the first dust filter net 131.

[0062] The industrial control computer 100 provided by the embodiment of the present application not only performs dust prevention treatment on both the air inlet 1111 and the air outlet 1121, but also designs two dust preventions for the air inlet 1111 where dust is more likely to enter. The first dust prevention uses an electrostatic filter net to filter dust, and at the same time can adsorb the charged dust on it to prevent the charged dust from entering the inside of the fuselage 110 and affecting the stability of the circuit structure. The second dust prevention further filters the dust through the cooperation of the first dust filter net and the dust prevention and ventilation member. Part of the dust passing through the electrostatic filter net will collide with the dust prevention and ventilation member and deposit under the action of gravity, so that the dust prevention and ventilation member can also block part of the dust, and finally the first dust filter net performs the final filtration to ensure that very little dust enters the inside of the fuselage 110, thereby improving the overall dust prevention performance of the industrial control computer 100 and ensuring the stable and reliable operation of the internal circuit.

[0063] To ensure the flatness of the surface of the industrial control computer 100, the present application further proposes an implementation manner. Specifically, please refer to again Figure 4 and Figure 6 . As shown in the figure, a first recess 1112 is provided on the first panel 111, and the air inlet 1111 is provided on the bottom wall of the first recess 1112. The first dust-proof component 130 covers the outside of the air inlet 1111 and is located within the first recess 1112. The second dust-proof component 140 further includes a first cover plate 142, the first cover plate 142 is rotatably covered at the opening of the first recess 1112, a first ventilation hole 1421 is provided on the first cover plate 142, and the second dust-proof net 141 covers the inside of the first ventilation hole 1421.

[0064] Specifically, the first recess 1112 can be integrally formed with the first panel 111 to ensure the tightness of the internal space of the fuselage 110. Of course, it can also be a split structure with the first panel 111. Correspondingly, the two can also be a split structure and sealed and connected by a sealing strip.

[0065] As Figure 4 shown, a stepped first flange 11121 can be provided at the edge of the opening of the first recess 1112. When the first cover plate 142 rotates and closes, it is embedded within the first flange 11121 (as Figure 1 shown), ensuring the overall flatness of the outer surface of the first panel 111. Further, sealing strips can be provided at the relative positions between the first flange 11121 and the first cover plate 142 to ensure the sealing of the edge after the first cover plate 142 rotates and closes, achieving a dust-proof effect.

[0066] In this embodiment, the rotatable first cover plate 142 is adopted, so that the first cover plate 142 can rotate to close and open the space inside the first recess 1112. When the industrial control computer 100 is working, the first cover plate 142 is closed to ensure that the two dust-proof structures at the air inlet end each exert good dust-proof capabilities. Since the dust blocked by the dust-proof ventilation member 132 will deposit in the first recess 1112, when it is necessary to clean the space inside the first recess 1112, opening the first cover plate 142 can facilitate the operation.

[0067] As Figure 4 shown, in some embodiments, a switch button 1112a and an indicator light 1112b can be provided inside the first recess 1112, and a transparent observation window 142a can be provided at the position on the first cover plate 142 opposite to the indicator light 1112b, so that technicians can conveniently see the state of the internal indicator light 1112b through the transparent observation window 142a.

[0068] Considering that the second dust-proof net 141, which is the first dust-proof measure at the air inlet end, is prone to dust accumulation and blockage after being used for a period of time, it is generally necessary to frequently clean, maintain or replace the second dust-proof net 141. In order to facilitate the disassembly and assembly of the second dust-proof net 141, the present application further proposes an implementation manner. Please continue to refer to Figure 6 As shown in the figure, the second dust-proof assembly 140 further includes a second mounting bracket 143. The second mounting bracket 143 covers the outer periphery of the second dust-proof net 141 and is detachably connected to the inner wall of the first cover plate 142. A second ventilation hole 1431 is formed at a position of the second mounting bracket 143 opposite to the second dust-proof net 141.

[0069] In Figure 6 the specific embodiment shown, the second mounting bracket 143 is detachably connected to the inner wall of the first cover plate 142 by hand-tightening screws. In some other embodiments, structures such as buckles and pins can also be used, which are not limited herein.

[0070] By covering the outer periphery of the second dust-proof net 141 with the second mounting bracket 143 and detachably connecting it to the inner wall of the first cover plate 142, the reliable fixation of the second dust-proof net 141 is achieved, and at the same time, the disassembly, maintenance or replacement operation of the second dust-proof net 141 is facilitated.

[0071] Regarding the opening, closing and locking of the first cover plate 142, the present application proposes an implementation manner. Please refer to Figure 8 The figure shows the structure of the inner wall of the first recess 1112. As Figure 8 shown in the figure, a first clamping interface 11122 is formed on the side wall of the first recess 1112. As Figure 4 shown in the figure, a first knob 1422 is penetratingly provided on the first cover plate 142. A first clamping portion 1423 is provided at one end of the first knob 1422 located inside the first cover plate 142. The first knob 1422 is used to drive the first clamping portion 1423 to rotate and engage or disengage with the first clamping interface 11122, so as to close or open the first cover plate 142. As Figure 8 shown in the exploded state in the figure, the inner wall of the first recess 1112 around the first clamping interface 11122 is hermetically covered with a first dust-proof cover 11123.

[0072] By using the method of rotationally engaging the first clamping portion 1423 on the first knob 1422 with the first clamping interface 11122 on the side wall of the first recess 1112, the rapid closing and locking as well as opening of the first cover plate 142 can be achieved. Considering that the first clamping interface 11122 is directly connected to the inside of the fuselage 110, which may cause dust to enter from the first clamping interface 11122, a first dust-proof cover 11123 is covered on the inner wall of the first clamping interface 11122 to ensure the dust-proof inside the fuselage 110.

[0073] For the convenience of cleaning, maintenance and replacement of the third dust-proof component 150, it can be arranged in the same manner as the second dust-proof component 140. For details, please refer to Figure 2 and Figure 5 , as shown in the figure, a second recess 1122 is provided on the second panel 112. The third dust-proof component 150 includes a second cover plate 151, a third dust-proof net 152 and a third mounting bracket 153. The second cover plate 151 is rotatably covered at the opening of the second recess 1122. A third ventilation hole 1511 is provided on the second cover plate 151. The third dust-proof net 152 is arranged on the inner wall of the second cover plate 151 at the position of the third ventilation hole 1511 and covers the third ventilation hole 1511. The third mounting bracket 153 covers the outer periphery of the third dust-proof net 152 and is detachably connected to the inner wall of the second cover plate 151. A fourth ventilation hole 1531 is provided at the position of the third mounting bracket 153 opposite to the third dust-proof net 152.

[0074] Specifically, the third dust-proof component 150 in this embodiment can adopt the same structure as the second dust-proof component 140. For example, as shown in Figure 5 , a second overlapping edge 11221 is provided at the edge of the opening of the second recess 1122 so that the second cover plate 151 is embedded within the second overlapping edge 11221 after being closed, ensuring the flatness of the surface of the second panel 112 after the second cover plate 151 is closed. And sealant strips can also be provided on the edge of the inner wall of the second cover plate 151 and the second overlapping edge 11221 to ensure the sealing performance inside the second recess 1122 after the second cover plate 151 is closed.

[0075] The third mounting bracket 153 can also be detachably connected to the inner wall of the second cover plate 151 by means such as hand-tightening screws, buckles or pins, etc., to facilitate the cleaning, maintenance and replacement of the third dust-proof net 152.

[0076] The industrial control computer 100 requires a large number of expansion interfaces to connect with external devices for communication. In order to improve the dust-proof performance at the interfaces, the present application further proposes an implementation manner. For details, please refer to Figure 2 and Figure 5 , as shown in the figure, an interface 170 is provided on the bottom wall of the second recess 1122. The interface 170 is used to connect to an external device (not shown) through a cable (not shown). A wire passing hole 1512 is provided on the second cover plate 151. An elastic retaining piece 1513 is arranged in the wire passing hole 1512. The elastic retaining piece 1513 is used for the cable to pass through and seal the space between the second cover plate 151 and the second recess 1122.

[0077] Specifically, a rubber plug can be embedded in the wire passing hole 1512. A few rubber sheets in the hollow area of the rubber plug form an elastic retaining piece 1513. The elastic retaining piece 1513 will deform under the pressure of the wire cable after the wire cable passes through and abut against the outer periphery of the wire cable to play a certain sealing role. Multiple wire cables passing through the elastic retaining piece 1513 can also be bundled together by a wire binding tube and closely fit with each other to ensure the tightness between the wire cables.

[0078] The opening, closing and locking of the second cover plate 151 can adopt the same structure as that of the first cover plate 142. For details, please refer to Figure 5 again, and further in combination with Figure 9 , Figure 9 The structure of the inner wall of the second recess 1122 is shown. As shown in the figure, a second clamping interface 11222 is provided on the side wall of the second recess 1122. A second knob 1514 is provided through the second cover plate 151. A second clamping portion 1515 is provided at one end of the second knob 1514 located inside the second cover plate 151. The second knob 1514 is used to drive the second clamping portion 1515 to rotate and screw into or out of the second clamping interface 11222 to close or open the second cover plate 151. A second dust-proof cover 11223 is provided on the inner wall of the second recess 1122 around the second clamping interface 11222.

[0079] The closing and locking and opening of the second cover plate 151, and the dust-proof function of the second dust-proof cover 11223 for the second clamping interface 11222 are the same as the relevant structures and principles of the first cover plate 142 described above, and will not be elaborated here.

[0080] For the heat dissipation and dust prevention of the power supply of the industrial control computer 100, the present application also proposes an implementation manner. For details, please refer to Figure 2 , Figure 5 and Figure 9 . As shown in the figure, a power supply module 180 is provided inside the fuselage 110. The power supply module 180 has a power supply fan 181. A power supply heat dissipation port 1123 is provided on the second panel 112. The power supply fan 181 is disposed opposite to the power supply heat dissipation port 1123. The power supply fan 181 is used to blow air outward through the power supply heat dissipation port 1123 to achieve heat dissipation of the power supply module 180. A fourth dust-proof component 190 is provided outside the power supply heat dissipation port 1123.

[0081] Specifically, as shown in Figure 5 , the fourth dust-proof component 190 can adopt the same structure as the third dust-proof component 150 to achieve, and will not be elaborated here. By carrying out corresponding dust-proof design for the power supply module 180, the whole industrial control computer 100 can achieve a good dust-proof effect, and at the same time meet the heat dissipation requirements of the power supply module 180 and other internal circuit structures.

[0082] To improve the heat dissipation efficiency of the industrial control computer 100, an implementation manner is proposed in this application. For details, please refer to Figure 10 and Figure 11 . The figures show the internal structure of the fuselage and the gas flow direction from two perspectives respectively. As shown in the figures, the fan assembly 120 includes a first fan group 1201 and a second fan group 1202. The first fan group 1201 is arranged inside the first panel 111, and the second fan group 1202 is arranged inside the second panel 112. The first fan group 1201 is used to draw air inwards, and the second fan group 1202 is used to blow air outwards. The space inside the fuselage 110 between the first fan group 1201 and the second fan group 1202 forms a heat dissipation channel 113. The gas flow direction during the operation of the industrial control computer 100 is as shown by the arrows in the figures.

[0083] In Figure 10 and Figure 11 the specific embodiments shown, both the first fan group 1201 and the second fan group 1202 each include two fans. One fan in the first fan group 1201 corresponds to the CPU area 114 and the graphics card 115 inside the fuselage 110, and the other fan corresponds to the hard disk 116 and the power module 180, realizing targeted blowing heat dissipation for the main heat-generating components inside the fuselage 110. The two fans in the second fan group 1202 are arranged adjacent to each other and integrated at the interface 170, ensuring the compactness of the circuit element layout on the second panel 112. While the first fan group 1201 draws air inwards, combined with the heat dissipation channels at the graphics card 115 and the hard disk 116 and the self-power fan 181 of the power module 180 and the outward air supply of the second fan group 1202, the air duct of the industrial control computer 100 is smooth from the first panel 111 to the second panel 112 as a whole, and the air ducts of the two major heat-generating components, the power module 180 and the CPU, are separated from each other and do not affect each other, ensuring excellent overall heat dissipation performance of the industrial control computer 100.
