Description

Technical Field

[0001] This utility model belongs to the field of power management technology, specifically a liquid-medium circulating heat dissipation integrated power supply. Background Technology

[0002] With the continuous advancement of integrated power supply technology based on liquid-medium circulating cooling, such power systems have been widely applied in data centers, industrial control, and new energy fields. However, existing technical solutions still have some problems in practical applications. For example, traditional liquid-medium circulating cooling systems typically rely on external pumping equipment to circulate the coolant, which not only increases the system's complexity and energy consumption but also makes it prone to pumping equipment failure during long-term operation, affecting the system's stability and reliability. To address these issues, some researchers and companies have attempted to improve heat dissipation efficiency and reduce dependence on external power sources by optimizing coolant flow channel design and rectifier component layout. Although these methods improve cooling performance to some extent, they still have limitations, especially in high power density and high heat load applications, where natural coolant circulation may not meet the demand for rapid heat dissipation, thus limiting the improvement of overall system performance.

[0003] Specifically, a search revealed a liquid-medium circulating cooling integrated power supply with publication number CN219269421U, published on June 27, 2023. This design, through the rational configuration of the rectifier components and coolant flow channels, utilizes the principle of coolant density reduction after heat absorption to automatically form coolant circulation within the containment cavity, thereby improving the cooling effect on the rectifier components. However, this design relies on natural convection of the coolant. When the system heat load increases sharply, natural convection may not respond in time, leading to localized overheating and affecting the stable operation of the power supply system.

[0004] Therefore, existing technologies suffer from insufficient heat dissipation efficiency, high system complexity, and low reliability when dealing with high power density and high heat load applications. To address these issues, this invention proposes an integrated power supply with liquid-medium circulating cooling, aiming to improve heat dissipation efficiency and system stability by optimizing the coolant circulation mechanism and rectifier component layout, thus adapting to a wider range of application scenarios.

[0015] The structure and implementation principle of this utility model are as follows: A rectifier element is installed in the cavity inside the power supply casing. The coolant circulation system pumps coolant from the coolant radiator into the coolant pipeline via a coolant pump. The coolant then enters the coolant flow channel through the coolant pipeline. The main flow channel spirals around the rectifier element, while the branch channels are distributed in a mesh pattern on the upper and lower surfaces of the rectifier element. The coolant circulates through the connecting pipes between the branch channels and the main flow channel. The coolant absorbs heat as it flows through the rectifier element. A one-way valve controls the flow direction of the coolant to prevent backflow. After absorbing heat, the coolant, driven by the coolant pump, enters the coolant radiator. The cooling fan inside the radiator dissipates the heat into the air, thus cooling the coolant. A temperature sensor monitors the temperature inside the power supply casing in real time. When the temperature exceeds a preset value, the temperature sensor sends a signal to the coolant pump and cooling fan, activating them to increase the coolant flow rate and the fan airflow, thereby improving heat dissipation efficiency. The shock-absorbing springs inside the support feet and the anti-slip pads on the bottom can reduce the vibration of the power supply during operation, improving the stability and safety of the equipment.

[0016] The beneficial effects of this utility model are:

[0017] The design of the spiral main channel and mesh branch channels of the coolant flow channel increases the contact area between the coolant and the rectifier components, improves heat dissipation efficiency, ensures that the rectifier components can be adequately cooled in high power density applications, and extends the service life of the equipment.

[0018] Through real-time monitoring by temperature sensors and coordinated control of coolant pumps and cooling fans, intelligent heat dissipation management is achieved. It can automatically adjust the coolant flow rate and cooling fan airflow according to actual temperature changes, ensuring stable operation of the equipment under different environmental conditions.

[0019] The design of heat-conducting plates and microporous structures enhances the heat conduction between the rectifier components and the coolant, further improving the heat dissipation effect. At the same time, the use of sealing rings ensures the sealing of the coolant flow channels, preventing coolant leakage and improving the safety and reliability of the equipment.
