Description

Technical Field

[0001] This utility model relates to the field of UPS power supply heat dissipation technology, and in particular to a heat dissipation channel structure for a UPS power supply overheat protection device. Background Technology

[0002] An UPS (Uninterruptible Power Supply) is a power backup device that integrates energy storage and inverter technology. It is mainly used to ensure the continuous power supply needs of critical equipment in the event of abnormal power grid conditions. It consists of modules such as batteries, inverters, and rectifiers, and can switch to battery power in milliseconds when the mains power fails, so as to maintain the continuous operation of the equipment.

[0003] In traditional UPS power supplies, the battery and related components are tightly installed inside the equipment casing. Due to the limited internal space of the casing, and the heat radiated to the outside by the battery, rectifier, and inverter during operation, the overall temperature of the UPS power supply rises significantly, interfering with the operation of related power components. To improve heat dissipation and reduce operating temperature, a heat dissipation channel structure for a UPS power supply overheat protection device is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a heat dissipation channel structure for an overheat protection device for UPS power supplies, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of this utility model provides a heat dissipation channel structure for a UPS power supply overheat protection device, including a hollow base. A mounting groove is provided in the middle of one side of the base, and four fans are installed side-by-side inside it. Several first through slots are provided in the middle of the top surface of the base. A support frame is installed on the top surface of the base. Three vertically placed partition plates are installed on one side inside the support frame, dividing the interior of the support frame into three parts. Multiple battery placement racks are located on one side inside the support frame. Multiple second through slots are provided on the bottom surface of the multiple battery placement racks. Multiple limiting blocks are installed inside the multiple battery placement racks. A protective cover is installed on the outer wall of the support frame. Operating through slots are provided on all four sides of the protective cover. First sealing plates are installed on three sides of the protective cover near the operating through slots, and two second sealing plates are rotatably installed on the other side. A top cover is installed at the top of the support frame. All four sides of the top cover are bent downwards, and an air outlet slot is reserved between the top cover and the top of the protective cover.

[0006] Preferably, in any of the above solutions, the side of the base away from the mounting groove is hollowed out, and a side plate is installed inside it. This solution facilitates the provision of an installation position for the side plate. At the same time, the hollowed-out structure on one side of the base allows the operator to observe the operation of the four fans. During installation, it provides space for the fans to be installed, making it convenient for the operator to perform the installation operation. The four corners of the side plate are fixed to the base with screws, which facilitates the sealing of the hollowed-out area and prevents air from leaking from the inside of the base to the outside.

[0007] Preferably, one side of the mounting groove is equipped with a filter screen, which facilitates the filtration of air entering the base to remove dust and particulate matter. The mesh size is usually selected as 80-200 mesh.

[0008] Among them, 80-120 mesh is suitable for ordinary environments and can block dust particles with a diameter of about 125-180μm, balancing filtration efficiency and airflow speed, and avoiding heat dissipation obstruction.

[0009] 150-200 mesh: Suitable for dusty or precision environments, it intercepts fine particles of 50-100μm and requires regular cleaning to prevent clogging.

[0010] If the UPS power supply needs to be exposed to harsh environments such as high dust levels for a long time, the mesh size can be increased to 200-300 mesh; if heat dissipation performance is the priority (such as for overclocking hosts), the mesh size can be reduced to 40-60 mesh, filtering out larger impurities while ensuring smooth airflow.

[0011] The filter screen is generally made of 304 / 316L stainless steel plain or twill woven mesh.

[0012] Preferably, in any of the above solutions, the support frame is equipped with six limiting guide rails, and the two sides of the three partition plates are slidably connected to the two adjacent limiting guide rails. This solution facilitates the provision of installation positions for the three partition plates, thereby making it easier to divide the internal space of the support frame into three parts: one large and two small. The battery and battery rack are installed in the larger space, and the battery rack is installed layer by layer with a certain distance between each layer, which facilitates the insertion or removal of the battery and the installation of screws and connecting jumpers using a right-angle electric wrench.

[0013] Preferably, in any of the above solutions, a mounting bracket is installed on the side of the two spacers on the same side away from the battery placement rack, and a power device body is installed on one side of each of the two mounting brackets. In this solution, after the two spacers on the same side are installed, it is convenient to provide an installation position for the mounting bracket. The middle part of the mounting bracket protrudes from the side away from the spacer, thereby facilitating air circulation. The power device body includes rectifiers, inverters, etc. In order to increase the contact area between the power device body and the external air, heat dissipation fins can be installed on its outer shell, thereby allowing air to flow from bottom to top, which helps to reduce the operating temperature of the power device body.

[0014] Preferably, in any of the above solutions, all four sides of the three first sealing plates are fixedly connected to the protective cover by screws, and the adjacent sides of the two second sealing plates are rotatably connected to one side of the protective cover by hinges. This solution allows operators to easily remove the screws using tools, thereby disassembling the three first sealing plates. The side of the second sealing plate away from the hinge is fixed by a lock, which facilitates the later disassembly of the three first sealing plates and the rotation and opening of the two second sealing plates, making it convenient for maintenance or repair of the battery, power device body, etc.

[0015] This utility model has the following advantages:

[0016] 1. The heat dissipation channel structure of this UPS power supply overheat protection device includes a base, support frame, protective cover, and top cover. Air outlet slots are provided between the four sides of the top cover and the top of the protective cover. Multiple second through slots are provided on the bottom surface of multiple battery racks, and multiple first through slots are provided in the center of the top surface of the base. Four fans are powered on, drawing air into the base and allowing it to flow upwards through the multiple first through slots, passing over the multiple battery racks from bottom to top, and exiting through the air outlet slots. This airflow carries away the heat generated by the batteries and power devices during operation, reducing the overall operating temperature and effectively solving the problems existing in the prior art.

[0017] 2. The heat dissipation channel structure of this UPS power supply overheat protection device includes a base with four fans and side plates installed on both sides. A filter screen is installed inside the mounting slot to filter the air entering the base and improve the air cleanliness. Three first sealing plates and two second sealing plates are installed. The three first sealing plates can be removed and the second sealing plates can be opened to facilitate the inspection and maintenance of the internal battery and power device.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0028] like Figures 1 to 8 As shown, a heat dissipation channel structure for an overheat protection device of a UPS power supply includes a hollow base 1. A mounting groove 5 is provided in the middle of one side of the base 1, and four fans 13 arranged side-by-side are installed inside it. Several first through slots 15 are provided in the middle of the top surface of the base 1. A support frame 12 is installed on the top surface of the base 1. Three vertically placed partition plates 11 are installed on one side inside the support frame 12, dividing the interior of the support frame 12 into three parts. Multiple battery placement racks 10 are located on one side inside the support frame 12. Multiple second through slots 19 are provided on the bottom surface of the multiple battery placement racks 10. Multiple limiting blocks 20 are installed inside the multiple battery placement racks 10. The limiting blocks 20 facilitate the support of multiple batteries 9, allowing air to flow through the outer wall of the batteries 9, thus facilitating heat dissipation from the batteries 9.

[0029] The outer wall of the support frame 12 is equipped with a protective cover 4. The protective cover 4 has operation slots on all four sides. The three sides of the protective cover 4 closest to the operation slots are equipped with first sealing plates 2, and two second sealing plates 7 are rotatably installed on the other side. The top of the support frame 12 is equipped with a top cover 3. The four sides of the top cover 3 are bent downwards, and an air outlet slot 8 is reserved between it and the top of the protective cover 4.

[0030] The top cover 3 is made of metal and is manufactured by stamping. The top cover 3 is fixedly connected to the top of the support frame 12 by screws, thereby stabilizing the installation of the top cover 3 and keeping the distance of the air outlet slot 8 stable, so as to make use of the chimney effect and the operation of the fan 13 to accelerate air circulation.

[0031] The base 1 has a hollowed-out side away from the mounting groove 5, and a side plate is installed inside it. As an optional technical solution of this utility model, this facilitates the provision of an installation position for the side plate. At the same time, the hollowed-out structure on one side of the base 1 makes it easy for the operator to observe the operation status of the four fans 13. In addition, it provides installation and operation space for the fans 13 during installation, making it easy for the operator to perform installation operations. The four corners of the side plate are fixedly connected to the base 1 with screws, which makes it easy to seal the hollowed-out position and prevent the air inside the base 1 from leaking out from it.

[0032] A filter screen 6 is installed on one side inside the mounting slot 5. As an optional technical solution of this utility model, it is convenient to filter the air entering the base 1 to remove dust and particulate matter. The mesh size is usually selected as 80-200 mesh.

[0033] Among them, 80-120 mesh is suitable for ordinary environments and can block dust particles with a diameter of about 125-180μm, balancing filtration efficiency and airflow speed, and avoiding heat dissipation obstruction.

[0034] 150-200 mesh: Suitable for dusty or precision environments, it intercepts fine particles of 50-100μm and requires regular cleaning to prevent clogging.

[0035] If the UPS power supply needs to be exposed to harsh environments such as high dust levels for a long time, the mesh size can be increased to 200-300; if heat dissipation performance is the priority, it can be reduced to 40-60 mesh, filtering out larger impurities while ensuring smooth airflow.

[0036] The material of filter screen 6 is generally 304 / 316L stainless steel plain or twill woven mesh.

[0037] The support frame 12 has six limiting guide rails 16 installed inside. The two sides of the three partition plates 11 are slidably connected to the two adjacent limiting guide rails 16. As an optional technical solution of this utility model, this facilitates the provision of installation positions for the three partition plates 11, and thus facilitates the division of the internal space of the support frame 12 into three parts: one large and two small. The battery 9 and the battery placement rack 10 are installed inside the larger space. The battery placement rack 10 is installed layer by layer, with a certain distance between each layer, which facilitates the insertion or removal of the battery 9 and the installation of screws and connecting jumpers using a right-angle electric wrench.

[0038] On the side of the two partition plates 11 on the same side away from the battery placement rack 10, a fixing frame 17 is installed. On one side of each fixing frame 17, a power device body 14 is installed. As an optional technical solution of this utility model, after the two partition plates 11 on the same side are installed, it is convenient to provide an installation position for the fixing frame 17. The middle part of the fixing frame 17 protrudes on the side away from the partition plate 11, which facilitates air circulation. The power device body 14 includes a rectifier, an inverter, etc. In order to increase the contact area between the power device body 14 and the external air, several heat dissipation fins 18 can be installed on its outer shell, so that the air flows from bottom to top, which helps to reduce the temperature of the power device body 14 during operation.

[0039] The three first sealing plates 2 are fixedly connected to the protective cover 4 on all four sides by screws. The two second sealing plates 7 are rotatably connected to one side of the protective cover 4 by hinges on adjacent sides. As an optional technical solution of this utility model, this makes it easy for operators to use tools to disassemble the screws, thereby disassembling the three first sealing plates 2. The side of the second sealing plate 7 away from the hinge is fixed by a lock, which facilitates the disassembly of the three first sealing plates 2 and the rotation and opening of the two second sealing plates 7 in the future, making it convenient to maintain or repair the battery 9, power device body 14, etc.

[0040] This UPS power supply overheat protection device heat dissipation channel structure requires the following steps for use:

[0041] 1) When in use, the four fans 13 are powered on and run, driving air from the mounting slot 5 into the interior of the base 1, while the filter screen 6 filters the dust in the air;

[0042] 2) Air rises along multiple first channels 15, passing sequentially through multiple battery racks 10, batteries 9 and power device bodies 14, carrying away the heat generated during operation and reducing the operating temperature of the UPS power supply.

[0043] In summary, during use, the system comprises a base 1, a support frame 12, a protective cover 4, and a top cover 3. Air outlet slots 8 are provided between the four sides of the top cover 3 and the top of the protective cover 4. Multiple second through slots 19 are provided on the bottom surfaces of the battery racks 10, and multiple first through slots 15 are provided in the center of the top surface of the base 1. Four fans 13 are powered on, drawing air into the base 1. The air then flows upward through the multiple first through slots 5, passing over the multiple battery racks 10 from bottom to top, and exiting through the air outlet slots 8. This airflow carries away the batteries 9 and the power device bodies 14. The heat generated during operation reduces the overall operating temperature, thereby effectively solving the problems existing in the prior art. Furthermore, by setting up a base 1, four fans 13 and side plates are installed on both sides respectively. At the same time, a filter screen 6 is installed inside the mounting slot 5, which facilitates the filtration of the air entering the base 1 and improves the cleanliness of the air. By setting up three first sealing plates 2 and two second sealing plates 7, the three first sealing plates 2 can be removed, and the second sealing plates 7 can be opened to facilitate the inspection and maintenance of the internal battery 9 and power device body 14.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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.
