Description

Technical Field

[0001] This utility model relates to the field of heat dissipation device technology, specifically a split-type heat dissipation device for an electromagnetic valve. Background Technology

[0002] In industrial automation and the operation of various electromechanical equipment, solenoid valves are key control components, and their stability and reliability are of paramount importance. During operation, solenoid valves inevitably generate a significant amount of heat due to factors such as coil energization, hysteresis and eddy current losses in the iron core, and resistance to fluid flow.

[0003] Currently, there are various heat dissipation methods and devices for solenoid valves on the market. Traditional heat dissipation devices are mostly integrated structures, requiring the entire device to be disassembled or installed from the solenoid valve during installation. This is extremely inconvenient, especially when the solenoid valve is installed inside equipment with limited space or a compact layout. The disassembly and replacement of such integrated heat dissipation devices often consumes a lot of time and effort, seriously affecting the equipment maintenance efficiency and downtime costs.

[0004] Furthermore, existing heat dissipation devices are not well-suited for compatibility with solenoid valves. Because different models and specifications of solenoid valves vary in their outer dimensions and shapes, and these integrated heat dissipation devices lack sufficient flexibility and versatility, they cannot fit well against the outer surfaces of various solenoid valves, resulting in low heat transfer efficiency and significantly reduced heat dissipation performance.

[0005] Therefore, we propose a split-type heat dissipation device for solenoid valves. Utility Model Content

[0006] The purpose of this invention is to provide a split-type heat dissipation device for a solenoid valve to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a split-type heat dissipation device for a solenoid valve, comprising:

[0008] Two symmetrically arranged combined heat dissipation frames, each of which has an inner wall with a covering cavity matching the outer contour of the solenoid valve, and each of which has multiple heat dissipation fins distributed on its outer surface.

[0009] The two combined heat dissipation frames are detachably connected, and a flexible thermal pad is fitted inside the cavity of each combined heat dissipation frame.

[0010] This invention features a detachable connection design for the two combined heat dissipation frames, making installation and maintenance easier and increasing flexibility. The encapsulation cavity can fit the outer contour of the solenoid valve and, with the addition of a flexible thermal pad, can fit tightly against the valve body to improve heat transfer efficiency and quickly conduct heat, thereby enhancing the heat dissipation effect.

[0011] Furthermore, the two combined heat dissipation frames are connected by multiple screws, and the cross-section of each heat dissipation fin is in the shape of a straight line.

[0012] During installation, the solenoid valve can be placed between the two combined heat dissipation frames, aligning the encasing cavity, and then the screws can be gradually tightened. This causes the flexible thermal pad to deform under pressure, tightly adhering to the valve body surface, thereby improving the heat dissipation effect of the solenoid valve.

[0013] Furthermore, the two combined heat dissipation frames are connected by two pairs of quick-release components, which are located on both sides of the two combined heat dissipation frames.

[0014] Furthermore, one of the combined heat dissipation frames is provided with a plurality of positioning posts, and the other combined heat dissipation frame is provided with a plurality of positioning holes, each positioning post corresponding to a positioning hole, and each positioning post being inserted into the corresponding positioning hole.

[0015] Furthermore, each pair of quick-release components includes two mounting seats, which are respectively disposed on the sides of the two combined heat dissipation frames. One mounting seat is provided with a locking post, and the other mounting seat is provided with a through groove that matches the locking post. The other mounting seat is provided with a moving rod that engages with the locking post.

[0016] Furthermore, the movable rod is slidably connected within the mounting base, and a locking block is provided on the side of the movable rod near the locking post. A locking groove is provided on the locking post, and the locking block engages with the locking groove.

[0017] Furthermore, a spring is provided at the bottom of the movable rod, the mounting base where the movable rod is located is hollow, the bottom of the spring is fixedly connected to the inner wall of the mounting base, and a pressing plate is provided at the top of the movable rod.

[0018] When installing the two combined heat dissipation frames, first align the positioning posts with the corresponding positioning holes and apply pressure. At this time, the front end of the locking post will exert a squeezing effect on the locking block, the spring will be compressed, and finally the locking block can be quickly inserted into the locking groove, so as to quickly complete the connection and fixation of the two combined heat dissipation frames.

[0019] Furthermore, each of the heat dissipation fins has a wavy cross-section, and each of the heat dissipation fins has multiple split grooves.

[0020] By designing the heat dissipation fins in a wave shape and opening multiple interrupted slots on each heat dissipation fin, the heat dissipation area of ​​each heat dissipation fin can be increased, further improving the heat dissipation effect on the solenoid valve.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This invention features a detachable connection design for the two combined heat dissipation frames, making installation and maintenance easier and increasing flexibility. The encapsulation cavity can fit the outer contour of the solenoid valve and, with the addition of a flexible thermal pad, can fit tightly against the valve body to improve heat transfer efficiency and quickly conduct heat, thereby enhancing the heat dissipation effect.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1, please refer to Figures 1-3 A split-type heat dissipation device for a solenoid valve, comprising:

[0035] Two symmetrically arranged combined heat dissipation frames 1, each combined heat dissipation frame 1 has an inner wall with a covering cavity 4 that matches the outer contour of the solenoid valve 6 (the solenoid valve is existing technology and is only shown in the figure), and each combined heat dissipation frame 1 has multiple heat dissipation fins 3 distributed on its outer surface.

[0036] The two combined heat dissipation frames 1 are detachably connected, and a flexible thermal pad 2 is fitted inside the enclosing cavity 4 of each combined heat dissipation frame 1.

[0037] This utility model adopts a detachable connection design for the two combined heat dissipation frames 1, which makes the installation and maintenance of the combined heat dissipation frames 1 easier and more flexible in use. The covering cavity 4 can adapt to the outer contour of the solenoid valve 6 and is equipped with a flexible heat-conducting pad 2, which can fit tightly to the valve body to improve heat conduction efficiency and quickly conduct heat, thereby improving the heat dissipation effect.

[0038] It should be noted that the two combined heat dissipation frames 1 can be made of aluminum alloy, and their inner walls are machined with covering cavities 4 that match the outer contour (such as cylindrical or polygonal) of the solenoid valve 6. The cavity depth of the covering cavity 4 covers the core heat-generating area of ​​the solenoid valve 6 (such as the coil and valve body). The outer surface of the combined heat dissipation frame 1 is uniformly distributed with I-shaped cross-section heat dissipation fins 3. The fin height can be 15mm-30mm and the spacing can be 5mm-8mm, forming a dense heat dissipation array.

[0039] Specifically, the two combined heat dissipation frames 1 are connected by multiple screws 5, and the cross-section of each heat dissipation fin 3 is in the shape of a straight line.

[0040] It should be noted that by designing the heat dissipation fins 3 in a straight line, the processing difficulty is lower and the actual production cost is also lower. Therefore, it is more suitable for heat dissipation of solenoid valves 6 with low heat generation.

[0041] In this embodiment, when installing the two combined heat dissipation frames 1, the solenoid valve 6 can be placed between the two combined heat dissipation frames 1, aligned with the covering cavity 4, and the screws 5 can be gradually tightened. This causes the flexible thermal pad 2 to deform under pressure and fit tightly against the valve body surface, thereby improving the heat dissipation effect on the solenoid valve 6.

[0042] Example 2 is an improvement on Example 1, and its difference from Example 1 is as follows:

[0043] Please see Figures 4-9 The two combined heat dissipation frames 1 are connected by two pairs of quick-release components, which are located on both sides of the two combined heat dissipation frames 1.

[0044] Specifically, one of the combined heat dissipation frames 1 is provided with multiple positioning posts 9, and the other combined heat dissipation frame 1 is provided with multiple positioning holes 10. Each positioning post 9 corresponds to a positioning hole 10, and each positioning post 9 is inserted into the corresponding positioning hole 10. Each pair of quick-release components includes two mounting seats 7, which are respectively located on the sides of the two combined heat dissipation frames 1. One mounting seat 7 is provided with a locking post 11, and the other mounting seat 7 is provided with a through groove that matches the locking post 11. The other mounting seat 7 is also provided with a moving rod 13 that engages with the locking post 11.

[0045] Furthermore, the movable rod 13 is slidably connected within the mounting base 7. A locking block 15 is provided on the side of the movable rod 13 near the locking post 11. A locking groove 12 is provided on the locking post 11, and the locking block 15 is engaged with the locking groove 12. A spring 14 is provided at the bottom of the movable rod 13. The mounting base 7 where the movable rod 13 is located is hollow. The bottom of the spring 14 is fixedly connected to the inner wall of the mounting base 7. A pressing plate 16 is provided at the top of the movable rod 13. A flange is provided at the front end of the locking post 11. A ramp that matches the flange is provided at the top of the locking block 15, so that the locking post 11 can smoothly press the locking block 15 downward.

[0046] It is worth mentioning that when installing the two combined heat dissipation frames 1, first align the positioning post 9 with the corresponding positioning hole 10 to complete the alignment of the two combined heat dissipation frames 1. Then apply pressure, at which time the front end of the locking post 11 will exert a squeezing effect on the locking block 15, the spring 14 will be compressed, and finally the locking block 15 can be quickly inserted into the locking groove 12, so as to quickly complete the connection and fixation of the two combined heat dissipation frames 1.

[0047] Similarly, when it is necessary to disassemble the two combined heat dissipation frames 1, simply press the two pressing plates 16, the moving rod 13 will compress the spring 14 downwards, and the locking block 15 will disengage from the locking groove 12, thus quickly completing the separation of the two combined heat dissipation frames 1.

[0048] The difference from Embodiment 1 is that the cross-section of each heat dissipation fin 3 is wavy, and each heat dissipation fin 3 has multiple split grooves 8.

[0049] By designing the heat dissipation fins 3 as wavy and opening multiple interrupted slots 8 on each heat dissipation fin 3, the heat dissipation area of ​​each heat dissipation fin 3 can be increased, further improving the heat dissipation effect on the solenoid valve 6. The wavy heat dissipation fins 3 are difficult to process and have higher production costs, making them suitable for heat dissipation of the solenoid valve 6 with high heat generation.

[0050] It should be noted that the cross-section of the wavy fin is a sinusoidal wave (where the amplitude can be 2mm and the wavelength can be 10mm), and the surface has a 3mm deep groove 8 with a spacing of 8mm, which can disrupt the boundary layer airflow, enhance turbulence, and improve the heat dissipation effect.

[0051] It should be noted that, although embodiments of the present invention have been shown and described herein, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
