Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for back domain controllers, and in particular to a back domain controller with heat dissipation function. Background Technology

[0002] With the rapid development of information technology, the back domain controller, as a core component of data centers and mission-critical systems, undertakes important tasks such as data storage, processing, and management. Its performance and stability directly affect the operating efficiency and reliability of the entire system. However, as the performance of core components such as processors and chips continues to improve, power consumption and heat generation also increase dramatically. Heat dissipation has become a key factor restricting the performance and lifespan of the back domain controller.

[0003] Traditional heat dissipation airflow layouts are often designed based on idealized models, failing to fully consider the complexity and dynamic changes in the distribution of heat-generating units during actual operation. Some back-end controllers have compact internal structures with densely packed heat-generating components such as CPUs, GPUs, and power modules, making it difficult to plan airflow rationally. At the same time, due to unreasonable placement and airflow direction of cooling fans, some heat-generating units cannot be effectively covered, and heat cannot be dissipated in time, accumulating inside the controller. Over time, this can not only lead to a decline in the performance of the back-end controller and malfunctions, but may even cause hardware damage and serious consequences such as data loss. Utility Model Content

[0004] In order to overcome the problem that the active heat dissipation efficiency of the existing back domain controller is low because its heat dissipation duct cannot cover the heat-generating unit, this utility model provides a back domain controller with heat dissipation function.

[0005] The technical solution is as follows: A rear domain controller with heat dissipation function includes a housing assembly and a heat dissipation assembly; the heat dissipation assembly is installed inside the housing assembly; the housing assembly includes a housing, an air intake grille, a rear domain controller, a data interface, heat dissipation fins, a rectifier, a heat sink, and a fan speed control knob; the heat dissipation assembly includes a cooling fan and a safety net; the cooling fan is installed inside the housing; air intake grilles are provided at both the top and bottom ends of the housing, and the air intake grilles are fixedly connected to the housing with screws; the rear domain controller is installed inside the housing.

[0006] Furthermore, the rear domain controller is fixedly connected to the inner wall of the housing by bolts; a heat dissipation fin is provided on one side of the rear domain controller, and the heat dissipation fin is integrally formed with the rear domain controller.

[0007] Furthermore, the cooling fan is located in front of the rear domain controller; a safety net is provided on the front face of the cooling fan, and the safety net is located on the front face of the housing, and the safety net is fixedly connected to the cooling fan by screws.

[0008] Furthermore, a rectifier is provided on one side of the rear domain controller, and the output terminal of the rectifier is electrically connected to the input terminal of the rear domain controller; a circuit board is provided at the lower end of the rectifier, and the circuit board at the lower end of the rectifier is fixedly connected to the inner wall of the housing by insulating screws.

[0009] Furthermore, a heat sink is provided on one side of the rectifier, and the heat sink is fixedly connected to the circuit board of the rectifier.

[0010] Furthermore, data interfaces are provided on both the front and rear end faces of the housing, and the data interfaces are electrically connected to the rear domain controller.

[0011] Furthermore, a fan speed control knob is provided on one side of the data interface, and the fan speed control knob is electrically connected to the cooling fan.

[0012] The beneficial effects are as follows: During equipment operation, the rear domain controller and rectifier are the main heat-generating units, and their heat dissipation is crucial for stable equipment operation. The integrated heat dissipation fins on the rear domain controller effectively increase the contact area with air by increasing the surface area, providing more paths for heat conduction. The heat dissipation bracket on one side of the rectifier enhances the heat dissipation capacity of its circuit board based on the principle of heat conduction. When the cooling fan starts, it generates negative pressure suction, and external air enters the equipment through the air intake grille. The air intake grille not only filters the incoming air to prevent foreign objects from entering the equipment, but also guides the airflow, allowing the air to flow through the heat-generating area at a reasonable speed and direction. The incoming air is driven by the cooling fan. The airflow flows along a specific air duct, evenly covering the surface of the heat dissipation fins and heat sink. During the airflow, it fully exchanges heat with the heat generated by the heat-generating unit, absorbing the heat in the flowing air. After the heat exchange is completed, the air is quickly discharged from the equipment under the continuous power of the cooling fan. This continuous air circulation ensures that there is always cool air around the heat dissipation fins and heat sink for heat exchange, so that the heat generated by the heat-generating unit can be carried away in time. In the entire heat dissipation process, the heat dissipation fins, heat sink, cooling fan, and air intake grille work together to form a highly efficient heat dissipation system through the synergistic effect of area expansion and airflow circulation, effectively improving the heat dissipation efficiency of the equipment and ensuring the stable operation of the equipment for a long time.

[0013] By setting the fan speed control knob, the rotation speed of the cooling fan can be controlled, thereby dynamically adjusting the efficiency of the cooling fan's air intake and heat exhaust, greatly improving the flexibility of equipment heat dissipation adjustment.

[0025] A rectifier 106 is provided on one side of the rear domain controller 103, and the output terminal of the rectifier 106 is electrically connected to the input terminal of the rear domain controller 103; a circuit board is provided at the lower end of the rectifier 106, and the circuit board at the lower end of the rectifier 106 is fixedly connected to the inner wall of the housing 101 by insulating screws.

[0026] A heat sink 107 is provided on one side of the rectifier 106, and the heat sink 107 is fixedly connected to the circuit board of the rectifier 106.

[0027] Data interfaces 104 are provided on both the front and rear ends of the housing 101, and the data interfaces 104 are electrically connected to the rear domain controller 103.

[0028] During equipment operation, the rear domain controller 103 and rectifier 106, as the main heat-generating units, are crucial for stable equipment operation due to their heat dissipation. The integrated heat sink fins 105 on the rear domain controller 103 effectively increase the contact area with air by increasing the surface area, providing more paths for heat conduction. The heat sink 107 on one side of the rectifier 106 enhances the heat dissipation capacity of its circuit board based on the principle of heat conduction. When the cooling fan 201 is started, it generates negative pressure suction, and external air enters the equipment through the air intake grille 102. The air intake grille 102 not only filters the incoming air to prevent foreign objects from entering the equipment, but also guides the airflow, ensuring that the air flows through the heat-generating area at a reasonable speed and direction. Driven by the cooling fan 201, the incoming air flows along... A specific airflow evenly covers the surfaces of the heat dissipation fins 105 and the heat sink 107. During the airflow, the heat generated by the heat-generating unit is fully exchanged, and the heat is absorbed in the flowing air. After the heat exchange is completed, the air is quickly discharged from the inside of the equipment under the continuous power of the cooling fan 201. This continuous air circulation ensures that there is always cool air around the heat dissipation fins 105 and the heat sink 107 for heat exchange, so that the heat generated by the heat-generating unit can be carried away in time. In the entire heat dissipation process, the heat dissipation fins 105, the heat sink 107, the cooling fan 201, and the air intake grille 102 work together to form a highly efficient heat dissipation system through the synergistic effect of area expansion and airflow circulation, effectively improving the heat dissipation efficiency of the equipment and ensuring the stable operation of the equipment for a long time.
