Description

Technical Field

[0001] This application relates to the technical field of heat sinks, and in particular to an external heat dissipation expansion module. Background Technology

[0002] Modern industrial PCs use an increasing number of components, all of which generate a significant amount of heat during operation. Among various heat dissipation methods, built-in fan cooling is widely used due to its low cost, significant cooling effect, and mature technology. However, considering that built-in fan failure is a major cause of industrial PC malfunctions, devices without built-in fans are generally more durable and reliable.

[0003] In existing technologies, fanless industrial PCs are industrial control computers that employ passively cooled technology. Fanless cooling is a heat dissipation solution for electronic devices, primarily achieving efficient heat dissipation through the use of high thermal conductivity materials, heat pipes, heat sinks, and optimized design. This technology eliminates dust and debris from entering the system, significantly improving the reliability and durability of the industrial PC. However, for computationally intensive applications, under high-temperature environments and high CPU loads, the fanless design of industrial PCs also has significant limitations in improving overall heat dissipation.

[0004] In summary, to avoid damage to control equipment caused by excessively high temperatures in industrial PCs due to fanless cooling technology, it is urgent to design an external cooling expansion module that can improve the cooling effect of industrial PCs without affecting their normal form. Utility Model Content

[0005] In order to improve the heat dissipation of the industrial control computer without affecting its normal form, this application provides an external heat dissipation expansion module.

[0006] This application provides an external heat dissipation expansion module, which adopts the following technical solution:

[0007] An external heat dissipation expansion module includes a bracket, a perforated protective mesh plate, and a cooling fan. The cooling fan is fixedly connected to the bracket. The side of the bracket closest to the cooling fan is mounted on the side of the industrial computer closest to the heat dissipation fins. A first through hole for heat dissipation of the industrial computer is opened on the bracket at the position corresponding to the cooling fan. The perforated protective mesh plate completely covers the first through hole.

[0008] By adopting the above technical solution, the bracket fixes the cooling fan to the side of the industrial computer near the heat sink fins. The rotation of the cooling fan removes the heat from the side of the industrial computer near the heat sink fins, and the heat is discharged through the first through hole, which can achieve efficient heat dissipation. The hollowed-out protective mesh plate can prevent dust or particles from entering the industrial computer.

[0009] Preferably, the bracket includes a main bracket and a mounting bracket. The main bracket is located on the side of the industrial computer near the heat sink fins. Two mounting brackets are provided, symmetrically mounted on both sides of the main bracket, and respectively mounted on the two side walls of the industrial computer. The main bracket and the mounting bracket are integrally formed, and the first through hole and the cooling fan are located on the main bracket.

[0010] By adopting the above technical solution, when the mounting bracket is fixed on the industrial computer, the bracket completely wraps around the heat dissipation fins of the industrial computer, ensuring the horizontal balance and symmetry of the bracket. The main bracket and the mounting bracket are integrally formed, eliminating the need for additional fasteners or complicated assembly steps during installation, which greatly simplifies the installation process and saves time and costs.

[0011] Preferably, the main support includes a main frame and a fixing base. The main frame is attached to the heat dissipation fins of the industrial control computer, and the fixing base is fixed to the side of the main frame near the cooling fan. The cooling fan has a first fixing hole, and a fixing screw passes through the first fixing hole. The fixing screw passes through the cooling fan and is screwed into the fixing base.

[0012] By adopting the above technical solution, the fixing base is used to fix the perforated protective mesh plate and the cooling fan with fixing screws, so as to realize the connection between the cooling fan, the perforated protective mesh plate and the main frame. This connection method is simple and easy to disassemble and clean the cooling fan.

[0013] Preferably, the main frame has a second through hole for heat dissipation of the industrial control computer.

[0014] By adopting the above technical solution, the second through hole is used to further dissipate the heat from the industrial control computer side, and this design can also reduce the weight of the bracket.

[0015] Preferably, the main support frame is also provided with a weight-reduction notch for reducing the weight of the main support frame.

[0016] By adopting the above technical solution, this design can further dissipate the heat from the side of the industrial computer near the heat sink fins through the weight-reducing notch on the bracket, while reducing the weight of the components and enhancing aesthetics.

[0017] Preferably, the mounting bracket includes a mounting side plate and two fixed legs. The mounting side plate is fixedly connected to the side wall of the main frame, and the two fixed legs are respectively fixedly connected to both ends of the mounting side plate. The mounting side plate and the main frame are directly opposite the heat dissipation fins of the industrial computer, and the fixed legs are mounted on the side wall of the industrial computer.

[0018] By adopting the above technical solution, when the bracket is installed on the industrial computer, the mounting side plate and the main frame are directly opposite the heat dissipation fins of the industrial computer, and the fixed legs are installed on the side wall of the industrial computer, so that the mounting bracket and the main frame completely cover the heat dissipation area of ​​the industrial computer.

[0019] Preferably, the fixed leg has a second fixing hole for fixing the mounting bracket, and the second fixing hole is used to insert the outer casing screw.

[0020] By adopting the above technical solution, the second fixing hole is used to insert the housing screw of the industrial control computer. This design can combine and connect the bracket with the main body of the industrial control computer without changing the main structure of the industrial control computer, so as to achieve a firm connection between the bracket and the industrial control computer.

[0021] Preferably, the mounting side plate has a third through hole for heat dissipation of the industrial control computer.

[0022] By adopting the above technical solution, the third through hole can improve the heat dissipation effect on the side of the industrial control computer, while reducing the weight of the bracket.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The bracket fixes the cooling fan to one side of the industrial computer. The cooling fan rotates and removes the heat from the side of the industrial computer closest to the heat sink fins. The heat is discharged through the first through hole, which can achieve efficient heat dissipation. The hollowed-out protective mesh plate can prevent dust or particles from entering the industrial computer.

[0025] 2. When the bracket is installed on the industrial computer, the mounting side plate and the main frame are aligned with the heat dissipation fins of the industrial computer, while the fixed legs are located on the side wall of the industrial computer, so that the mounting bracket and the main frame completely cover the heat dissipation area of ​​the industrial computer.

[0026] 3. The second fixing hole is used to insert the housing screw of the industrial control computer. This design allows the bracket to be combined and connected with the main body of the industrial control computer without changing the main structure of the industrial control computer, so as to achieve a firm connection between the bracket and the industrial control computer.

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0032] This application discloses an external heat dissipation expansion module, referring to... Figure 1 It includes a bracket 1 and a cooling fan 3. The cooling fan 3 is fixedly connected to the bracket 1. The side of the bracket 1 closest to the cooling fan 3 is installed on the side of the industrial computer closest to the heat dissipation fins. The rotation of the cooling fan 3 drives the surrounding air to flow faster, so that the heat of the heat dissipation fins can be transferred out more quickly, thus improving the heat dissipation effect of the industrial computer.

[0033] The bracket 1 includes a main bracket 11 and mounting brackets 12. The main bracket 11 is located on the side of the industrial computer closest to the heat sink fins. Two mounting brackets 12 are symmetrically mounted on both sides of the main bracket 11, and each mounting bracket 12 is mounted on one of the two side walls of the industrial computer. The cooling fan 3 is mounted on the side of the main bracket 11 closest to the industrial computer. In this embodiment, the main bracket 11 and mounting brackets 12 are integrally formed. In use, the bracket 1 completely encloses the heat sink fins of the industrial computer, ensuring a tight fit and improving the heat dissipation effect.

[0034] A first through hole 112 is provided through the main support 11 at the position corresponding to the cooling fan 3. The first through hole 112 is located at the center of the main support 11, allowing the hot air blown out by the cooling fan 3 to be discharged through the first through hole 112. (Refer to...) Figure 1 and Figure 2 The main support 11 includes a main frame 111 and a fixing seat 113. The main frame 111 is attached to the heat sink fins of the industrial control computer, and the fixing seat 113 is fixed to the side of the main frame 111 near the cooling fan 2. There are four fixing seats 113, which are evenly distributed around the first through hole 112. The fixing seats 113 are used to fix the cooling fan 3.

[0035] The main frame 111 is also provided with a second through hole 114 for heat dissipation of the industrial control computer. There are four second through holes 114, which are evenly distributed around the four fixed seats 113. The second through holes 114 help to reduce the overall weight of the main frame 111.

[0036] The main frame 111 is also provided with weight reduction notches 115. There are two weight reduction notches 115, which are located at the upper and lower ends of the main frame 111 respectively. The weight reduction notches 115 are symmetrically distributed with the axis of the center of the main frame 111 as the axis of symmetry. The weight reduction notches 115 are arc-shaped along the edge of the main frame 111. The weight reduction notches 115 can further dissipate the heat of the industrial control computer, while reducing the weight of the main frame 111, enhancing the visual effect of the main frame 111 and improving its aesthetics.

[0037] The mounting bracket 12 includes a mounting side plate 121 and fixed legs 124. The mounting side plate 121 is formed on the side wall of the main frame 111. Two fixed legs 124 are provided and formed at both ends of the mounting side plate 121, and the mounting side plate 121, fixed legs 124 and main frame 11 form a U-shaped structure. (Refer to...) Figure 1 and Figure 3 When bracket 1 is installed on the industrial computer, the mounting side plate 121 and the main frame 111 are directly opposite the heat dissipation fins of the industrial computer, while the fixed support leg 124 is located on the side wall of the industrial computer, so that the mounting bracket 12 and the main frame 11 completely cover the heat dissipation area of ​​the industrial computer.

[0038] To facilitate fixing the mounting bracket 12 to the industrial computer, a second fixing hole 123 is provided on the fixing leg 124. The second fixing hole 123 is used to pass through the housing screw 6 of the industrial computer, and the housing screw 6 passes through the second fixing hole and is screwed into the industrial computer. This design allows the bracket 1 to be combined and connected with the industrial computer without changing the main structure of the industrial computer, thus achieving a firm connection between the bracket 1 and the industrial computer.

[0039] To further improve the heat dissipation of the industrial control computer, a third through hole 122 is provided on the mounting side plate 121. The third through hole 122 is located at the end of the mounting side plate 121 away from the main frame 111.

[0040] The bracket 1 is cut and bent from sheet metal, which can reduce the area of ​​the bracket 1 while meeting the required area for the installation of the cooling fan 3, and further reduce the overall weight of the bracket 1.

[0041] The cooling fan 3 has four first fixing holes 5, which are symmetrically distributed around the center of the cooling fan 3. A fixing screw 4 passes through each first fixing hole 5 and is screwed into the fixing base 113. In this application, four fixing screws 4 are positioned corresponding to the fixing holes 5. During use, all four fixing screws 4 pass through the cooling fan 3 and are fixed to the fixing base 113, thus connecting the cooling fan 3 and the main frame 111. The connection method is simple and easy to disassemble and clean.

[0042] To prevent large particles from entering the cooling fan 3, a perforated protective mesh plate 2 is fixed between the bracket 1 and the cooling fan 3, and the perforated protective mesh plate 2 completely covers the first through hole 112.

[0043] The implementation principle of this application embodiment is as follows: the screws 6 of the industrial control computer’s outer shell pass through the bracket 1, so that the bracket 1 completely covers the heat dissipation area of ​​the industrial control computer. At the same time, the cooling fan 3 acts on the industrial control computer. This design can improve the heat dissipation effect of the industrial control computer without affecting its normal shape.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
