Description

Technical Field

[0001] This utility model relates to the field of power module technology, specifically a novel combined power module. Background Technology

[0002] A power line carrier communication module is a device that uses existing power lines as the transmission medium to transmit data signals. Its core function is to allow power lines, which are originally only responsible for transmitting electrical energy, to also function as "communication lines," enabling information exchange between devices without the need for additional dedicated communication cables. The current data transmitted by the power line carrier communication module allows monitoring systems or control centers to remotely control circuit breakers. Based on the monitored current data, the circuit breaker can be switched on or off to promptly cut off or restore power supply, ensuring the safe operation of the power system. Currently, power line carrier communication modules are electrically connected by pins plugged into the sockets of circuit breakers.

[0003] In existing technologies, such as the power line carrier communication module disclosed in CN221380929U, a rectangular opening is provided at the middle of both ends of the housing, and a pin is disposed within the rectangular opening with an annular boss on its periphery; a rectangular groove is provided at the connection between the bottom wall and the side wall of the housing, the rectangular groove being located at the middle of the connection; a T-shaped groove is provided through both side walls of the housing, communicating with the rectangular groove; it also includes a rectangular block disposed within the rectangular groove, and a T-shaped groove is provided on any side wall of the rectangular block. It works by manually pulling on the L-shaped pieces on both sides, the L-shaped pieces moving along the L-shaped grooves; when the limiting strip moves to the T-shaped groove, it is blocked, and the spring disengages from the L-shaped piece, and the force is applied to the circuit breaker, causing the pin of the power line carrier communication module to be pulled out along with the manual pulling force.

[0004] The existing module allows manual pulling of the L-shaped plates on both sides, which move along the L-shaped groove. When the limiting strip moves to the second T-shaped groove, it is blocked, and the spring disengages from the L-shaped plate. The force is applied to the circuit breaker, and the pins of the power line carrier communication module are pulled out along with the manual pulling force. However, it is inconvenient to dissipate heat inside the module during use, and ventilation and heat dissipation are difficult, which leads to accelerated aging of electronic components inside the module and unstable operation of the module. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the above-mentioned or existing technologies have problems such as inconvenience in heat dissipation inside the module during use, difficulty in ventilation and heat dissipation, accelerated aging of electronic components inside the module, and instability in module operation.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A novel combined power module includes: a power line carrier module body, a connector, and a positioning rod; the connector is fixed to one end of the power line carrier module body, and the positioning rod is welded and fixed to one side of the power line carrier module body; it also includes:

[0009] A protective housing and a semiconductor cooling chip; the protective housing is disposed at the other end of the power line carrier module body, and the semiconductor cooling chip is disposed inside the protective housing.

[0010] As a further embodiment of this utility model: the protective shell includes a mounting cavity, which is formed on the inner wall of the protective shell, and a limit spring is fixed at the lower end inside the mounting cavity.

[0011] As a further improvement of this utility model: the upper surface of the limiting spring abuts against the limiting rod, and a pull plate is integrally fixed to the side wall of the limiting rod.

[0012] As a further improvement of this utility model: the pull plate has a limiting groove opened on the protective shell for external sliding connection, and four fixing bolts that are threadedly connected to the power line carrier module body are installed on one side of the protective shell.

[0013] As a further embodiment of this invention: the semiconductor cooling chip includes heat dissipation fins, which are fixed to one side of the semiconductor cooling chip.

[0014] As a further improvement of this utility model: a cooling fin is fixed to the other side of the semiconductor cooling chip, and two fixing plates are fixed to the side wall of the protective shell.

[0015] As a further improvement of this utility model: two circulating fans are installed inside each of the two fixed plates, and a mounting plate is fixed to one side of the heat dissipation fins by screws.

[0016] As a further improvement of this utility model: a cooling fan is installed inside the mounting plate, and a sealing gasket is bonded to the inner side of the protective shell.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model uses a semiconductor cooling chip to cool the heat-conducting fins. The circulating fans in the two fixed plates are activated, and the air is cooled as it circulates through the heat-conducting fins. This allows the air to re-enter the power line carrier module and dissipate heat from the internal electronic components, thus ensuring the service life of the electronic components. The heat dissipation fins can absorb the heat generated by the semiconductor cooling chip during operation, and the heat dissipation fans on the mounting plate blow air onto the heat dissipation fins to further ensure the service life of the semiconductor cooling chip.

[0019] 2. After the limiting rod comes into contact with the power distribution equipment, it can move vertically in the installation cavity, thereby pushing the limiting spring to compress. When the power carrier module is fully pushed in, the limiting spring will push the limiting rod to reset during its own extension and reset process, so that the upper end of the limiting rod is inserted into the limiting hole inside the power distribution equipment, thereby limiting the power carrier module and preventing it from falling off.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] 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 in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Example 1:

[0030] Please see Figure 1 - Figure 5 This is the first embodiment of the present invention, which provides a novel combined power module, including: a power line carrier module body 1, a connector 2, and a positioning rod 3. The connector 2 is fixed to one end of the power line carrier module body 1, and the positioning rod 3 is welded and fixed to one side of the power line carrier module body 1. It also includes:

[0031] The protective housing 4 and the semiconductor cooling chip 5 are disposed at the other end of the power line carrier module 1, and the semiconductor cooling chip 5 is disposed inside the protective housing 4.

[0032] Specifically, the protective shell 4 includes a mounting cavity 41, which is formed on the inner wall of the protective shell 4. A limit spring 42 is fixed at the lower end inside the mounting cavity 41. The upper surface of the limit spring 42 abuts against a limit rod 43. A pull plate 44 is integrally fixed to the side wall of the limit rod 43.

[0033] Furthermore, after the limiting rod 43 contacts the power distribution equipment, it can move vertically within the mounting cavity 41, thereby pushing the limiting spring 42 to compress. When the power carrier module 1 is fully pushed in, the limiting spring 42 will push the limiting rod 43 to reset during its own extension and reset process, so that the upper end of the limiting rod 43 is inserted into the limiting hole inside the power distribution equipment, thereby limiting the power carrier module 1.

[0034] Specifically, the external sliding connection of the pull plate 44 has a limiting groove 45 opened on the protective shell 4, and four fixing bolts 46 that are threadedly connected to the power line carrier module body 1 are installed on one side of the protective shell 4.

[0035] Furthermore, manually pull the pull plate 44 on the limit groove 45 vertically, thereby causing the limit plug 43 to separate from the power distribution equipment, which facilitates the disassembly of the power line carrier module 1. By unscrewing the fixing bolt 46, the protective shell 4 can be disassembled.

[0036] In use, the power line carrier module 1 is assembled. Using the connector 2 and positioning rod 3 on the power line carrier module 1, the connector 2 is aligned with the interface of the power distribution equipment. Then, the power line carrier module 1 is inserted horizontally into the slot of the power distribution equipment. The positioning rod 3 matches the positioning hole inside the power distribution equipment, thus achieving positioning. Using the limiting rod 43 on the protective shell 4, when the power line carrier module 1 is fully pushed in, the arc-shaped structure at the upper end of the limiting rod 43 allows it to contact the power distribution equipment and move vertically within the mounting cavity 41. The linear motion pushes the limiting spring 42 to compress. When the power carrier module 1 is fully pushed in, the limiting spring 42 will push the limiting rod 43 to reset during its own extension and reset process. This allows the upper end of the limiting rod 43 to be inserted into the limiting hole inside the power distribution equipment, thereby limiting the power carrier module 1 and preventing it from falling off. When disassembly is required, the pull plate 44 on the limiting groove 45 can be pulled vertically by hand to separate the limiting rod 43 from the power distribution equipment, making it easy to disassemble the power carrier module 1. The protective shell 4 can be disassembled by unscrewing the fixing bolt 46.

[0037] In summary, when this novel combined power module is in use, after the limiting rod 43 contacts the power distribution equipment, it can move vertically within the mounting cavity 41, thereby pushing the limiting spring 42 to compress. When the power carrier module 1 is fully pushed in, the limiting spring 42 will push the limiting rod 43 to reset during its own extension and reset process, so that the upper end of the limiting rod 43 is inserted into the limiting hole inside the power distribution equipment, thereby limiting the power carrier module 1 and preventing it from falling off.

[0038] Example 2:

[0039] Please see Figure 1 - Figure 5 This is the second embodiment of the present utility model.

[0040] Specifically, the thermoelectric cooler 5 includes heat dissipation fins 51, which are fixed on one side of the thermoelectric cooler 5. A cooling fin 52 is fixed on the other side of the thermoelectric cooler 5, and two fixing plates 53 are fixed on the side wall of the protective shell 4.

[0041] Furthermore, the semiconductor cooling chip 5 cools the cooling fins 52, and the circulating fans 54 in the two fixed plates 53 are started. When the air circulates through the cooling fins 52, it can be cooled, so that the air can dissipate heat from the internal electronic components after re-entering the power line carrier module 1.

[0042] Specifically, two circulating fans 54 are installed inside each of the two fixing plates 53, and a mounting plate 55 is fixed to one side of the heat dissipation fins 51 by screws. A heat dissipation fan 56 is installed inside the mounting plate 55, and a sealing gasket 57 is bonded to the inside of the protective shell 4.

[0043] Furthermore, the heat dissipation fins 51 can absorb the heat generated by the thermoelectric cooler 5 during operation, and the heat dissipation fan 56 on the mounting plate 55 blows air to dissipate heat from the heat dissipation fins 51, thereby ensuring the service life of the thermoelectric cooler 5.

[0044] In use, the semiconductor cooling chip 5 installed inside the protective shell 4 is activated, which can cool the cooling fins 52. At this time, the circulating fans 54 in the two fixed plates 53 are activated. One set of circulating fans 54 draws air from inside the power line carrier module 1 into the protective shell 4, and the other set of circulating fans 54 blows air from inside the protective shell 4 into the power line carrier module 1. When the air circulates through the cooling fins 52, it can be cooled, so that when the air re-enters the power line carrier module 1, it can dissipate heat for the internal electronic components, ensuring the service life of the electronic components. The heat dissipation fins 51 can absorb the heat generated by the semiconductor cooling chip 5 during operation. The heat dissipation fan 56 installed on the mounting plate 55 blows air to dissipate heat from the heat dissipation fins 51, thereby ensuring the service life of the semiconductor cooling chip 5. The sealing gasket 57 installed on the protective shell 4 can ensure the sealing effect between the protective shell 4 and the power line carrier module 1.

[0045] In summary, when the new combined power module is in use, after the limiting rod 43 contacts the power distribution equipment, it can move vertically within the mounting cavity 41, thereby pushing the limiting spring 42 to compress. When the power carrier module 1 is fully pushed in, the limiting spring 42 will push the limiting rod 43 to reset during its own extension and reset process, so that the upper end of the limiting rod 43 is inserted into the limiting hole inside the power distribution equipment, thereby limiting the power carrier module 1 and preventing it from falling off. Furthermore, the semiconductor cooling chip 5 cools the cooling fins 52, and the circulating fans 54 in the two fixing plates 53 are started. When the air circulates through the cooling fins 52, it can be cooled, so that when the air re-enters the power carrier module 1, it can dissipate heat for the internal electronic components, ensuring the service life of the electronic components. The heat dissipation fins 51 can absorb the heat from the side of the semiconductor cooling chip 5 during operation, and the heat dissipation fan 56 on the mounting plate 55 blows air to dissipate heat from the heat dissipation fins 51, thereby ensuring the service life of the semiconductor cooling chip 5.
