Description

Technical Field

[0001] This utility model relates to the field of industrial control computer heat dissipation technology, specifically a heat dissipation device for an embedded fanless industrial control computer. Background Technology

[0002] Embedded fanless industrial PCs, as a type of specially designed small integrated industrial computer, have always had heat dissipation as a major concern in the industry. The fanless design reduces noise and dust intrusion, improving the stability and reliability of the equipment. However, due to the high integration of internal modules, higher requirements are placed on the overall heat dissipation performance of the industrial PC.

[0003] In high-temperature environments, the heat generated by electronic components increases significantly. If heat dissipation is not timely, it can lead to overheating of the equipment, affecting performance or even causing damage. Embedded industrial computers usually adopt a fully enclosed design, which reduces the intrusion of dust and moisture, but also restricts the air circulation inside the embedded industrial computer, increasing the difficulty of heat dissipation and making it difficult for the heat inside the embedded industrial computer to dissipate quickly.

[0004] Existing industrial control computers often increase heat dissipation efficiency by installing cooling fans on heat sink fins. However, most common cooling fans are connected to the industrial control computer housing with screws, making the assembly and disassembly process cumbersome. Furthermore, because the fan and heat sink fins are tightly fitted, dust and other impurities easily accumulate in the gaps of the heat sink fins during prolonged operation, making cleaning difficult and reducing the heat conduction efficiency of the heat sink fins, rendering the cooling fan ineffective. Therefore, those skilled in the art provide an embedded fanless cooling device for industrial control computers to solve the problems mentioned in the background art. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a heat dissipation device for an embedded fanless industrial computer. This solves the problem that most existing industrial computer heat dissipation devices use screw-fixed cooling fans, which are cumbersome to install and remove. Furthermore, because the fan and heat sink fins are tightly fitted, the gaps in the heat sink fins are easily clogged with dust and other impurities during long-term operation, making them difficult to clean. This results in reduced heat conduction efficiency of the heat sink fins and the cooling fan performing ineffective work.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation device for an embedded fanless industrial computer, comprising a housing, a silicone pad, heat dissipation fins, and a heat dissipation fan. The silicone pad is disposed on the upper side of the housing, the heat dissipation fins are attached to the upper side of the silicone pad, and the heat dissipation fan is disposed above the heat dissipation fins. Sliding grooves are provided on both sides of the housing, and first limiting slots are provided in the four corners of the heat dissipation fan. Limiting bolts are slidably engaged in the first limiting slots, and springs are sleeved on the limiting bolts. A clamping plate is installed at the end of the limiting bolts away from the sliding grooves. A second limiting slot is provided on the bottom side of the heat dissipation fan, and a limiting strip is slidably engaged in the second limiting slot. A brush plate is installed on the bottom side of the limiting strip, and a toothed groove is provided on one side of the limiting strip. A toothed disc is provided on one side of the toothed groove, and a stepper motor is connected to the upper side of the toothed disc.

[0009] Preferably, the stepper motor is fixedly installed with the cooling fan, and the stepper motor is connected to the gear drive.

[0010] Preferably, the toothed disc engages with the toothed side of the limiting strip. When the stepper motor drives the toothed disc to rotate back and forth, the limiting strip drives the brush plate to scrape back and forth on the heat dissipation fins, thereby cleaning the impurities on the heat dissipation fins.

[0011] Preferably, one end of the spring is connected to the end of the limiting bolt, and the other end of the spring is pressed against the inner wall of one end of the opening of the first limiting slot. Under the compression of the spring, the limiting bolt drives the two sides of the bottom shell of the clamping plate to clamp together.

[0012] Preferably, the bottom end of the clamping plate is slidably engaged with the sliding groove to increase the stability of the cooling fan.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a heat dissipation device for an embedded fanless industrial computer, which has the following beneficial effects:

[0015] Through design, the industrial control computer heat dissipation device in this utility model consists of a housing, silicone pads, heat dissipation fins, a heat dissipation fan, and a brush plate. A first limiting slot is provided in the four corners of the heat dissipation fan. A limiting bolt is slidably engaged in the first limiting slot. A spring is sleeved on the limiting bolt, and a clamping plate is installed at the end of the limiting bolt away from the first limiting slot. Under the compression of the spring, the limiting bolt drives the two sides of the bottom housing of the clamping plate to clamp and engage with the slot. This clamping and engaging structure facilitates the disassembly and assembly of the heat dissipation fan.

[0016] Furthermore, a second limiting slot is provided on the bottom side of the cooling fan. A limiting strip is slidably engaged in the second limiting slot. A brush plate is installed on the bottom side of the limiting strip. A toothed groove is provided on one side of the limiting strip. When the stepper motor drives the toothed disc to rotate back and forth, the limiting strip drives the brush plate to scrape back and forth on the heat dissipation fins, thereby cleaning the impurities on the heat dissipation fins and preventing the gaps of the heat dissipation fins from being blocked, which would reduce the heat conduction efficiency of the heat dissipation fins and cause the cooling fan to work in vain.

The gear plate 12 is engaged with the side of the limiting strip 8 with the toothed groove 9. When the stepper motor 11 drives the gear plate 12 to rotate back and forth, the limiting strip 8 drives the brush plate 10 to scrape back and forth on the heat dissipation fins 3, thereby cleaning the impurities on the heat dissipation fins 3. One end of the spring 6 is connected to the end of the limiting bolt 5, and the other end of the spring 6 is pressed against the inner wall of the opening of the first limiting groove 401. Under the compression of the spring 6, the limiting bolt 5 drives the clamping plate 7 to clamp the two sides of the bottom shell 1. The bottom end of the clamping plate 7 is slidably engaged with the sliding groove 101 to increase the stability of the cooling fan 4.

[0024] The industrial computer heat dissipation device in this utility model consists of a housing 1, silicone pads 2, heat dissipation fins 3, a cooling fan 4, and a brush plate 10. The housing 1 is equipped with a power interface, a network cable interface, a USB interface, a Type-C interface, and a temperature control component. The silicone pads 2 are double-layered, highly adhesive, and thermally conductive. The heat dissipation fins 3 are thermally conductive aluminum-type fine-toothed heat dissipation fins. The cooling fan 4 is located above the heat dissipation fins 3. When the temperature reaches 50℃, the cooling fan 4 is activated by the temperature control component for rapid heat dissipation. When the industrial computer temperature remains within the normal range, heat dissipation is achieved through layer-by-layer heat conduction by the silicone pads 2 and the heat dissipation fins 3, improving the stable operation of the system. Essentially, it reduces the risk of system downtime and eliminates the dangerous operation caused by system downtime due to high summer temperatures, achieving inherent safety. It also prevents equipment offline, shutdown, and impacts on the accuracy of instrument measurements and the continuity of data transmission caused by industrial computer system downtime. Furthermore, it avoids industrial computer downtime caused by high summer temperatures, thus preventing equipment system failures, reducing manual maintenance and equipment repair costs, and improving system operating efficiency.

[0025] A first limiting slot 401 is provided in the four corners of the cooling fan 4. A limiting bolt 5 is slidably engaged in the first limiting slot 401. A spring 6 is sleeved on the limiting bolt 5, and a clamping plate 7 is installed at the end of the limiting bolt 5 away from the first limiting slot 401. Under the compression of the spring 6, the limiting bolt 5 drives the clamping plate 7 to clamp the two sides of the bottom shell 1. The bottom end of the clamping plate 7 is slidably engaged with the sliding grooves 101 on both sides of the shell 1, which increases the stability of the cooling fan 4. This clamping and engaging structure makes it convenient to disassemble and assemble the cooling fan 4.

[0026] Furthermore, a second limiting slot 402 is provided on the bottom side of the cooling fan 4. A limiting strip 8 is slidably engaged in the second limiting slot 402. A brush plate 10 is installed on the bottom side of the limiting strip 8. The brush plate 10 is a bristle brush that can adapt to the heat dissipation fins 3 with different spacing. A toothed groove 9 is provided on one side of the limiting strip 8. A toothed disc 12 is engaged on one side of the toothed groove 9. A stepper motor 11 is driven and connected to the upper side of the toothed disc 12. The stepper motor 11 is fixedly installed on the frame of the cooling fan 4. When the stepper motor 11 drives the toothed disc 12 to rotate back and forth, the limiting strip 8 drives the brush plate 10 to scrape back and forth on the heat dissipation fins 3, thereby cleaning the impurities on the heat dissipation fins 3 and preventing the gaps of the heat dissipation fins 3 from being blocked, which would reduce the heat conduction efficiency of the heat dissipation fins 3 and cause the cooling fan 4 to work in vain.
