Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for energy storage equipment, and in particular to a heat dissipation module for converting air-cooled to liquid-cooled energy storage converters. Background Technology

[0002] With the rapid expansion of the new energy storage market, the operating environment of energy storage systems is becoming increasingly complex. To improve integration, most current energy storage products adopt an integrated AC / DC compartment design. However, current energy storage converters (PCS) generally use forced air cooling, achieving air convection between the inside and outside of the compartment through louvers for cooling.

[0003] This air-cooling method has significant drawbacks: when the equipment is used in harsh environments such as high dust, sandstorms, heavy rainfall, and high pollution, the louvers are insufficient to effectively block external environmental corrosion of the equipment inside the cabin, resulting in inadequate equipment protection. Furthermore, relying on air convection for heat dissipation can easily lead to excessively high overall temperatures inside the cabin, thereby affecting the lifespan of electrical components and the reliability of system operation.

[0004] Therefore, there is an urgent need for a heat dissipation solution for energy storage converters that can adapt to harsh environments, dissipate heat efficiently, and maintain a clean and stable thermal environment inside the chamber. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an air-cooled to liquid-cooled heat dissipation module for energy storage converters in order to overcome the shortcomings of the existing technology.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an air-cooled to liquid-cooled heat dissipation module for an energy storage converter, which is installed in the electrical compartment of the energy storage cabinet. The electrical compartment is equipped with a control cabinet, a transformer, an energy storage converter PCS, a gas-liquid heat exchanger, and a liquid cooling unit.

[0007] The energy storage converter PCS is equipped with a fan for blowing out the heat emitted from its air outlet during operation. The gas-liquid heat exchanger includes a heat exchange module and a front heat exchange fan for blowing hot air toward the heat exchange module, and a rear heat exchange fan for blowing the cold air after heat exchange toward the air inlet of the energy storage converter PCS. The heat exchange module includes liquid cooling pipes, which are connected to the liquid cooling unit.

[0008] Air circulation channels are arranged between the installation compartments of the control cabinet, transformer, energy storage converter (PCS), and gas-liquid heat exchanger, forming a closed, internally circulating heat dissipation loop within the electrical compartment.

[0009] Furthermore, the cooling capacity of the gas-liquid heat exchanger described in this invention is greater than the heat output of the energy storage converter pcs.

[0010] Furthermore, the transformer described in this utility model is installed at the bottom of the electrical compartment, the energy storage converter (PCS) is installed above the transformer, and the control cabinet is installed on one side of the transformer and the energy storage converter (PCS).

[0011] Furthermore, the front and rear displacement heat exchange fans on the gas-liquid heat exchanger of this utility model are arranged in a staggered manner.

[0012] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model has the following significant advantages:

[0013] 1. By converting the heat dissipation method to a closed-loop internal circulation within the electrical compartment, the impact of harsh external environments such as high dust levels, sandstorms, and heavy rainfall on the equipment inside the compartment is completely isolated, improving the environmental adaptability and reliability of the entire energy storage system; 2. Liquid cooling has a much higher heat exchange efficiency than traditional air convection cooling, which can more effectively remove the heat generated by the energy storage converter, helping to improve the energy conversion efficiency and operational stability of the energy storage converter; 3. The closed-loop circulation prevents the entry of external hot air, while the efficient heat exchange reduces the overall temperature inside the compartment, providing a better working environment for other electrical components and extending the service life of the equipment; 4. Compared to high-power fans that directly exhaust heat to the outside, internal circulation fans and liquid cooling units can usually be designed to be quieter, helping to reduce the overall operating noise of the equipment.

[0019] like Figure 1 and Figure 2 The energy storage converter air-cooled to liquid-cooled heat dissipation module shown is installed in the electrical compartment 2 of the energy storage cabinet 1. The electrical compartment 2 is equipped with a control cabinet 3, a transformer 4, an energy storage converter pcs 5, a gas-liquid heat exchanger 6, and a liquid cooling unit 7.

[0020] The energy storage converter PCS5 is equipped with a fan for blowing out the heat emitted from its air outlet during operation.

[0021] Air circulation channels 9 are arranged between the installation compartments of control cabinet 3, transformer 4, energy storage converter pcs5 and gas-liquid heat exchanger 6, forming a closed, internal circulation heat dissipation loop within the electrical compartment 2.

[0025] Working principle:

[0026] Within the sealed electrical compartment, the heat generated by the energy storage converter (PCS) during operation is exhausted from the exhaust vents by its internal fan, creating a hot airflow that permeates the compartment. A gas-liquid heat exchanger within the compartment, equipped with a front-mounted heat exchange fan, draws in hot air and directs it towards the heat exchange module inside the gas-liquid heat exchanger. The hot air is cooled as it flows through the condenser pipes within the heat exchange module, transforming into cold air. This cold air is then guided back to the energy storage converter's air inlet by a rear-mounted heat exchange fan, completing a closed-loop air cooling process within the electrical compartment.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
