Description

Technical Field

[0001] This invention relates to the field of computer equipment technology, and in particular to a heat dissipation device for communication network cabinets. Background Technology

[0002] A network cabinet is a mounting enclosure used to assemble and install panels, plug-ins, boxes, electronic components, devices, and mechanical parts and components into a complete unit. It provides a suitable environment and security for the normal operation of electronic equipment. Network cabinets generate a significant amount of heat during use; failure to dissipate this heat in a timely manner can damage the internal electronic components.

[0003] Current technologies for heat dissipation and dehumidification of network cabinets typically involve creating openings in the cabinet or pre-installing exhaust fans. However, these exhaust fans need to be constantly running during operation, leading to resource waste. Furthermore, due to the openings or exhaust fans, external dust can easily enter the network cabinet. Therefore, a heat dissipation device is designed that can be activated when heat dissipation is needed and deactivated when not, effectively preventing external dust from entering. It is also easy to install and requires no external power source. Summary of the Invention

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0033] Example 1

[0034] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a heat dissipation device for a communication network cabinet. The heat dissipation device for the communication network cabinet includes a heat dissipation component 100 and a mounting component 200. The heat dissipation component 100 can adaptively dissipate heat from the network cabinet, and the mounting component 200 can be conveniently and quickly installed and disassembled.

[0035] Specifically, the heat dissipation assembly 100 includes a top cover 101, a cylinder 102 disposed inside the top cover 101, and a first spring 103 disposed between the cylinder 102 and the top cover 101. An air inlet 104 is also disposed on the top of the cylinder 102. The top cover 101 is normally sealed to the outer wall of the cabinet, forming a compression chamber M-1 between it and the outer wall of the cabinet, and a pressure relief chamber M-2 between it and the cylinder 102 and the pressure rod 202a. The first spring 103 is a tension spring, which normally keeps the top cover 101 tightly fitted to the outer wall of the cabinet.

[0036] Preferably, the mounting assembly 200 includes a clamping member 201 disposed inside the upper part of the cylinder 102, and a locking member 202 disposed inside the center of the cylinder 102. The clamping member 201 applies pressure from the outer wall of the cabinet, and cooperates with the locking member 202 to securely mount the device on the network cabinet.

[0037] In use, the device is first installed in the mounting holes on the network cabinet using the clamping member 201 and locking member 202. When the temperature inside the network cabinet rises and the gas begins to expand, the high-pressure gas passes through the cylinder 102 into the compression chamber M-1 and the pressure relief chamber M-2 between the top cover 101 and the outer wall of the cabinet. This gradually lifts the top cover 101, allowing the inside of the network cabinet to connect with the outside and begin heat dissipation. When the temperature and pressure inside the network cabinet decrease, the top cover 101 begins to fall back. Due to the presence of the pressure relief chamber M-2, the gas inside cannot escape quickly but can only escape slowly. Therefore, the top cover 101 falls back at a slow speed, extending the heat dissipation time and ensuring the heat dissipation effect. When heat dissipation is not needed, the top cover 101 can be closed to prevent dust from entering.

[0038] Example 2

[0039] Reference Figures 2-11 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, the top cover 101 is umbrella-shaped, with a perforation 101a at its center. An annular protrusion 101b is also provided on the inner side of the top cover 101, and the annular protrusion 101b is integrally connected to the top cover 101. The umbrella shape of the top cover 101 facilitates its being lifted by gas, and the annular protrusion 101b is designed to cooperate with the cylinder 102 to form a certain sealed space and to limit its movement.

[0041] Preferably, the top of the cylinder 102 is provided with an annular groove 102a, which engages with an annular protrusion 101b. A slot 102b is also provided at the central axis of the cylinder 102. At least one channel 102c is provided around the cylinder 102. The channel 102c is divided into an upper channel 102c-1 and a lower channel 102c-2. Movable grooves 102c-2a are also provided on the two side walls of the lower channel 102c-2. In this embodiment, four elongated channels 102c are evenly provided around the cylinder 102. The channels 102c are interconnected and parallel to the central axis of the cylinder 102.

[0042] Preferably, the air inlet 104 includes at least one variable diameter channel 104a disposed at the top of the cylinder 102. A float 104b is disposed inside the variable diameter channel 104a. The diameter of the float 104b is larger than the minimum diameter of the variable diameter channel 104a but smaller than the maximum diameter of the variable diameter channel 104a. When the gas inside the cabinet expands, the gas will push open the float 104b and enter the pressure relief chamber M-2. Thus, the float 104b and the variable diameter channel 104a form a one-way valve, and the gas can only enter the pressure relief chamber M-2 from bottom to top through the variable diameter channel 104a.

[0043] Preferably, the clamping member 201 includes a second spring 201a disposed within the upper channel 102c-1, and a pressure plate 201b disposed at the bottom of the second spring 201a. The pressure plate 201b is slidably engaged with the cylinder 102, and the two ends of the second spring 201a are fixedly connected to the cylinder 102 and the pressure plate 201b, respectively. The second spring 201a is a compression spring, and the pressure plate 201b is annular with protrusions inside that allow it to slide up and down along the upper channel 102c-1. During installation, the second spring 201a will press the pressure plate 201b tightly against the outer wall of the network cabinet.

[0044] Preferably, the locking member 202 includes a pressure rod 202a disposed in the slot 102b. One end of the pressure rod 202a passes through a through hole 101a on the top cover 101, and the pressure rod 202a and the through hole 101a are clearance-fitted. The pressure rod 202a and the top cover 101 are in sliding fit, and there is a certain gap at the connection position between them. The gas that previously entered the depressurization chamber M-2 can only exit through this gap. Because the gap is very small, the gas discharge speed is very slow, so the top cover 101 can slowly fall back.

[0045] Preferably, the middle section of the pressure rod 202a is further provided with at least one shrinkage groove 202a-1. The shrinkage grooves 202a-1 are interconnected and communicate with the upper channel 102c-1 and the lower channel 102c-2. A first rotating shaft 202a-2 is also provided within the shrinkage groove 202a-1, and the first rotating shaft 202a-2 is fixedly connected to the pressure rod 202a. The number of shrinkage grooves 202a-1 is consistent with the number of channels 102c.

[0046] Preferably, the locking member 202 further includes a third spring 202b disposed at the bottom of the pressure rod 202a, the two ends of the third spring 202b being fixedly connected to the bottom of the pressure rod 202a and the bottom of the slot 102b, respectively. The third spring 202b is a compression spring, which always exerts an upward force on the pressure rod 202a.

[0047] Furthermore, the locking component 202 also includes a support arm 202c disposed within the lower channel 102c-2. A second rotating shaft 202c-1 is disposed at the middle position of the support arm 202c, and the second rotating shaft 202c-1 is placed within the moving groove 102c-2a. The support arm 202c is elongated and can rotate around the second rotating shaft 202c-1, while the second rotating shaft 202c-1 can move within the moving groove 102c-2a. This is so that the support arm 202c can be completely retracted into the cylinder 102 when needed.

[0048] Furthermore, one end of the support arm 202c is provided with a rotating groove 202c-2, which cooperates with the first rotating shaft 202a-2. When the pressure rod 202a moves upward, it drives the support arm 202c to rotate counterclockwise around the second rotating shaft 202c-1 in the direction shown in the figure via the first rotating shaft 202a-2. When the pressure rod 202a moves downward, the support arm 202c rotates clockwise. It is worth noting that the lower channel 102c-2 is not completely open inside and out, and there is still the outer wall of the cylinder 102 on the outer side. Therefore, when the support arm 202c rotates counterclockwise to a certain extent, it will be blocked and cannot rotate any further.

[0049] Based on the above, the usage method and working principle of this device are as follows:

[0050] The first step is installation. A hole of appropriate size needs to be drilled in the outer wall of the network cabinet. Then, the cylindrical part 102 of the device is directly inserted into the hole. At this time, the support arm 202c will be compressed and will retract until it enters the cabinet. Under the action of the third spring 202b, the pressure rod 202a will move upward, and the support arm 202c will reopen. On the other hand, since the diameter of the pressure plate 201b is larger than the diameter of the hole, it will be pressed tightly against the outer wall of the cabinet under the action of the second spring 201a. In this way, the support arm 202c and the pressure plate 201b are one inside and one outside, which can fix the device at the hole.

[0051] When disassembly is required, simply press down on the pressure rod 202a. The pressure rod 202a will move downward and break through the elastic force of the third spring 202b to continue moving downward. The end of the support arm 202c will be pulled by the first rotating shaft 202a-2, and will begin to move and rotate. Finally, it will rotate clockwise and retract into the cylinder 102 in the direction shown in the figure. At this time, without the obstruction of the support arm 202c, the entire device can be lifted out smoothly, and disassembly can be completed.

[0052] Heat dissipation principle: When the internal temperature of the network cabinet rises and the gas begins to expand, the expanding gas enters the compression chamber M-1 through the lower channel 102c-2 on the cylinder 102, the contraction groove 202a-1, and then the upper channel 102c-1. Since the weight of the top cover 101 is greater than the weight of the float 104b, the gas first fills the pressure relief chamber M-2. Then, the air pressure in both the compression chamber M-1 and the pressure relief chamber M-2 increases together until the top cover 101 is lifted. At this time, the inside and outside of the network cabinet are connected, and heat dissipation begins. After a period of time, the temperature drops and the air pressure decreases, and the top cover 101 begins to fall. However, because the pressure relief chamber M-2 is blocked by the float 104b, the gas inside can only be discharged through the gap between the pressure rod 202a and the top cover 101. However, because the gap is very small, the gas discharge speed is very slow, so the top cover 101 falls slowly, thereby prolonging the heat dissipation time and ensuring the heat dissipation effect.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
