Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary heat dissipation of industrial computers, and in particular to a heat dissipation device for an industrial computer. Background Art

[0002] An industrial computer (IPC), or industrial control computer, is a computer system designed specifically for industrial environments. Featuring a rugged housing, reliable performance, and strong anti-interference capabilities, IPCs operate stably in harsh environments, including high and low temperatures, high humidity, vibration, and electromagnetic interference. They are widely used in automation control, data acquisition, process monitoring, and equipment management. Key features include: industrial-grade components ensuring long-term continuous operation; a wide range of interfaces for easy connection to various industrial equipment; support for multiple operating systems to meet diverse application requirements; and a compact design for easy installation and maintenance. With the continuous advancement of industrial automation, IPCs are playing an increasingly important role in industries such as manufacturing, energy, transportation, and healthcare.

[0003] An industrial computer primarily consists of a motherboard. As the core of the computer, the motherboard integrates key components such as the CPU, memory, chipset, and power management unit, and serves as the hub for connecting various interfaces and expansion cards. Because the motherboard generates heat during operation, it requires cooling. This is typically achieved through heat sinks that contact the motherboard, increasing the surface area to improve heat exchange efficiency, quickly transferring heat to the radiator, and using fans to circulate air to remove the heat. However, different locations on the motherboard generate different amounts of heat, resulting in uneven heat distribution across the heat sink fins. Therefore, a constant fan speed cannot effectively dissipate heat from all locations on the heat sink, requiring increased fan speed to achieve adequate cooling, which is detrimental to reducing energy consumption.

DETAILED DESCRIPTION

[0029] The technical solution of the present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] The components of the embodiments of the present application generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application.

[0031] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

[0032] In the description of this application, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "two ends," "one end," "the other end," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0034] like Figures 1 to 9 As shown, the present invention proposes a heat dissipation device for an industrial computer, comprising a chassis 1, a motherboard fixedly mounted within the chassis 1, and a wiring port 101 fixedly mounted on the chassis 1 for electrical connection to the motherboard. Various industrial devices can be connected to the industrial computer through the wiring port. A radiator 102 is fixedly mounted within the chassis 1 and fixedly connected to the motherboard. Multiple silicone pads 1021 are fixedly mounted on the radiator 102, and the silicone pads 1021 conform to the heating elements on the motherboard. The radiator conducts heat from the motherboard, improving heat dissipation efficiency. The device also includes a heat dissipation box 2 fixedly mounted on the chassis 1, and multiple air ducts 201 fixedly mounted within the heat dissipation box 2. By placing the air ducts 201 at various locations within the heat dissipation box 2, the multiple air ducts 201 can cover the entire radiator, thereby providing air cooling to all locations on the radiator 102. The air output of each air duct 201 can be adjusted based on the heat generated at the point where the radiator 102 contacts the motherboard.

[0035] In this embodiment, the industrial computer heat dissipation device further includes a gas distribution component, which is installed within the heat dissipation box 2. The gas distribution component includes a fan assembly that provides driving force for the gas, and a distribution mechanism that distributes unequal amounts of gas to the interiors of different shrouds 201 while maintaining a constant gas flow from the fan assembly. The distribution mechanism adjusts the proportion of gas entering the interiors of the different shrouds 201. By having the fan assembly deliver gas to multiple shrouds 201 and using the distribution mechanism to rationally distribute the gas flow entering the different shrouds 201, the heat dissipation requirements of different radiator locations can be met when the fan assembly's output power is low, without increasing the fan assembly's output power, thereby effectively reducing energy consumption.

[0036] Furthermore, the fan assembly includes a fan 3 fixedly mounted inside the heat sink 2, a dust cover 204 fixedly mounted between the fan 3 and the heat sink 2, an air inlet 202 is provided at the top of the heat sink 2 and on the upper side of the fan 3, exhaust ports 203 are provided around the heat sink 2, and a filter is installed inside the exhaust port 203. The gas outside the heat sink 2 can be sucked into the heat sink 2 through the fan 3, and dust can be prevented from entering the heat sink 2 through the filter, thereby preventing the dust from affecting the radiator 102. A diverter box 301 is fixedly mounted on the fan 3, and a plurality of first connecting pipes 302 are fixedly mounted on the diverter box 301. The number of the first connecting pipes 302 is the same as the number of the air guide cover 201. The gas entering the fan 3 will enter the diverter box 301 and enter the plurality of first connecting pipes 302 through the diverter box 301.

[0037] Among them, the distribution mechanism includes a distribution box 303 fixedly installed on the first connecting pipe 302, one end of the distribution box 303 is provided with a first connecting hole 3031 connected to the first connecting pipe 302, and the other end of the distribution box 303 is provided with a second connecting hole 3032, a connecting head 304 is fixedly installed on the distribution box 303, the connecting head 304 is connected to the second connecting hole 3032, a sealing plate 305 for blocking the second connecting hole 3032 is slidably installed in the distribution box 303, and a pull rod 306 is fixedly installed on the sealing plate 305. The distribution mechanism also includes a control component that keeps the total effective flow area of ​​the multiple second connecting holes 3032 always equal. Gas entering the first connecting pipe 302 enters the distribution box 303 through the first connecting hole 3031 and enters the connector 304 through the second connecting hole 3032. The connector 304 corresponds to the air deflector 201 and is connected via an air pipe. By adjusting the effective flow area of ​​the multiple second connecting holes 3032, the amount of gas entering the air deflector 201 can be controlled. This is because, according to the continuity equation in fluid mechanics, for a closed system, under steady-state flow conditions, the flow rate through any cross-section is constant. This means that if the output power of the fan 3 remains constant, the total amount of gas passing through the fan 3 and the second connecting holes 3032 per unit time is constant. According to the Bernoulli equation in fluid mechanics, the velocity of a fluid (here, air) is inversely proportional to the cross-sectional area it passes through. That is, the smaller the area of ​​the hole, the faster the air passes through; conversely, the larger the area of ​​the hole, the slower the air passes through. In other words, the larger the area of ​​the second connecting hole 3032, the greater the amount of gas passing through it per unit time.

[0038] Furthermore, the control assembly includes a first oil barrel 308 fixedly mounted inside the heat sink 2. A pull rod 306 passes through the bottom of the first oil barrel 308 and extends into the interior of the first oil barrel 308. The ends of the first oil barrel 308 and the pull rod 306 are sealed. An oil tank 310 is fixedly mounted inside the heat sink 2. A partition 311 is fixedly mounted inside the oil tank 310. The upper and lower ends of the plurality of first oil barrels 308 are both connected to the oil tank 310, and the first oil barrels 308 are respectively connected to both sides of the partition 311. In order to accurately control the ratio of the effective flow areas of the plurality of second connection holes 3032, it is necessary to ensure that the sum of the effective flow areas of the plurality of second connection holes 3032 remains constant. When the effective flow area of ​​one of the second connection holes 3032 needs to be adjusted, the pull rod 306 needs to be pulled to move the sealing plate 305. By adjusting the area of ​​the second connection hole 3032 blocked by the sealing plate 305, the effective flow area of ​​the second connection hole 3032 can be controlled.

[0039] A first sealing head 309, equipped with a sealing ring, is fixedly mounted on the pull rod 306. Both the first oil barrel 308 and the oil tank 310 are filled with a first hydraulic medium 312. When the pull rod 306 is pulled, the first sealing head 309 moves, squeezing the first hydraulic medium 312 within the first oil barrel 308. This forces the first hydraulic medium 312 into the oil tank 310. However, the internal volume of the oil tank 310 is limited and cannot be expanded. Consequently, the first hydraulic medium that enters the oil tank 310 flows into the other first oil barrels 308, pushing the connected pull rod 306 to move. This reduces the flow area of ​​one of the second connecting holes 3032 and increases the area of ​​one or more of the remaining second connecting holes 3032, ensuring that the effective flow areas of the multiple second connecting holes 3032 are always equal.

[0040] Furthermore, multiple sets of positioning members are installed in the heat dissipation box 2 to fix the position of the pull rod 306, and the positioning members correspond one-to-one with the pull rod 306. The positioning members include a second oil barrel 313 fixedly installed in the heat dissipation box 2, a positioning rod 318 fixedly installed on the first sealing head 309, a handle 307 fixedly installed on the positioning rod 318, a second sealing head 319 fixedly installed on the positioning rod 318, and a sealing ring fixedly installed on the second sealing head 319. Second connecting pipes 314 are fixedly installed at the upper and lower ends of the second oil barrel 313, a valve is fixedly installed between the two second connecting pipes 314, and the second oil barrel 313, the second connecting pipe 314, and the interior of the valve are all filled with a second hydraulic medium 320. The positioning piece can be used to control whether the pull rod 306 can move, and thus can control whether the remaining pull rods 306 can move when adjusting the size of one of the second connecting holes 3032. When the pull rod 306 moves, it will drive the positioning rod 318 to move, and the moving positioning rod 318 will drive the second sealing head 319 to move. When the positioning rod 318 moves upward, the second hydraulic medium 320 located above the second sealing head 319 will flow through the second connecting pipe 314 and the valve into the bottom of the second sealing head 319. When the valve is closed, the second hydraulic medium 320 cannot flow, and thus cannot move the second sealing head 319, and thus cannot move the positioning rod 318 and the pull rod 306, so that the size of the second connecting hole 3032 can be fixed.

[0041] In this embodiment, the valve includes a valve body 315 fixedly mounted on two second connecting pipes 314. A valve core 316 is rotatably mounted within the valve body 315. A handle 317 is fixedly mounted on the valve core 316. The handle 317 extends through one side of the valve body 315 and extends to the outside of the valve body 315. Rotating the handle 317 rotates the valve core 316. Rotating the valve core 316 controls whether the valve core 316 blocks the valve body 315, thereby controlling the flow state of the valve body 315.

[0042] The working principle of this embodiment is as follows: the air outside the heat sink 2 is sucked into the heat sink 2 by the fan 3, and dust is prevented from entering the heat sink 2 through the filter, preventing the dust from affecting the radiator 102. The air entering the fan 3 will enter the diverter box 301 and then enter the multiple first connecting pipes 302 through the diverter box 301. The air entering the first connecting pipes 302 will enter the distribution box 303 through the first connecting hole 3031 and enter the connector 304 through the second connecting hole 3032. The connector 304 corresponds to the air deflector 201 one-to-one and is connected via an air pipe. By adjusting the effective flow area of ​​the multiple second connecting holes 3032, the amount of air entering the air deflector 201 can be controlled. When the effective flow area of ​​one of the second connecting holes 3032 needs to be adjusted, the pull rod 306 is pulled to move the sealing plate 305. By adjusting the area of ​​the second connecting hole 3032 blocked by the sealing plate 305, the effective flow area of ​​the second connecting hole 3032 can be controlled. When the pull rod 306 is pulled, the first sealing head 309 will be driven to move, and the moving first sealing head 309 will squeeze the first hydraulic medium 312 inside the first oil barrel 308, and the first hydraulic medium 312 will enter the oil tank 310. The accommodation space inside the oil tank 310 is limited and cannot be expanded, and the first hydraulic medium entering the oil tank 310 will enter the other first oil barrels 308 and push the pull rod 306 connected thereto to move, which reduces the flow area of ​​one of the second connecting holes 3032 and increases the area of ​​the remaining one or more second connecting holes 3032, thereby ensuring that the effective flow areas of multiple second connecting holes 3032 are always equal.

[0043] The positioning piece can be used to control whether the pull rod 306 can move, and thus can control whether the remaining pull rods 306 can move when adjusting the size of one of the second connecting holes 3032. When the pull rod 306 moves, it will drive the positioning rod 318 to move, and the moving positioning rod 318 will drive the second sealing head 319 to move. When the positioning rod 318 moves upward, the second hydraulic medium 320 located above the second sealing head 319 will flow through the second connecting pipe 314 and the valve into the bottom of the second sealing head 319. When the valve is closed, the second hydraulic medium 320 cannot flow, and thus cannot move the second sealing head 319, and thus cannot move the positioning rod 318 and the pull rod 306, so that the size of the second connecting hole 3032 can be fixed.

[0044] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
