TECHNICAL FIELD

[0002] In the research and development, production and debugging process of industrial power supply, the load plays a crucial role. As a key component of the test equipment, the load not only simulates the current and voltage requirements under actual working conditions, but also ensures the stability and reliability of the power supply under various working conditions. The design and configuration of the load are directly related to the performance verification and quality control of the power supply product. Traditionally, the load structure is mostly made of steel plates. In high-power application scenarios, significant heat accumulation occurs when a large current passes through the steel plate, which will seriously affect the stable operation of the load and the entire power supply system if not properly cooled.
[0003] In related technologies, in order to solve the heat dissipation problem of high-power loads under high-intensity work, a design scheme of installing the load in a water tank is generally adopted. The water tank is filled with cooling medium, which uses the good thermal conductivity of water to absorb and carry away the heat generated by the load, thereby achieving effective heat dissipation of the load. This design not only improves the heat dissipation efficiency of the load, but also prolongs the service life of the load, ensuring the safety and accuracy of the power supply debugging and testing process.
[0004] However, since industrial power supplies need to be debugged and tested in various different field environments after leaving the factory, and these environments often do not have the water tank and its supporting facilities required for installing high-power loads. This not only increases the complexity and cost of on-site deployment, but also limits the testing range and flexibility of power supply products, causing many inconveniences to power supply manufacturers and users.
