This application is aimed at the air-cooled liquid-cooled host 2. By changing the position of the air outlet, the energy storage cabinets can be closely arranged side by side and back to back, which can greatly save product costs and land costs.

Please refer to Figure 2. The liquid cooling host 2 is provided with an air inlet 23 corresponding to the first panel of the cabinet 1 and an air outlet corresponding to the second panel of the cabinet 1. The first panel is provided with an air inlet 23. The air reaches the air inlet 23 from the corresponding vent 10, and then the liquid cooling host 2 drives the air to continuously circulate, thereby achieving heat exchange with the heat dissipation medium and taking the heat of the heat dissipation medium out of the cabinet 1.

It should be noted that the first panel and the second panel are arranged opposite each other. The first panel and the second panel are usually the front panel and the rear panel of the cabinet 1, and the third panel is arranged between the first panel and the second panel. The third panel may be the top panel of the cabinet 1 or the bottom panel of the cabinet 1 . The liquid-cooled host is located between the first panel and the second panel.

A guide 24 for changing the air flow direction of the air outlet is provided between the air outlet and the second panel, so that the air can be discharged from the third panel of the cabinet 1 . In other words, when the air is discharged through the air outlet, it can be discharged out of the cabinet 1 through the third panel under the action of the air guide 24, thereby dissipating the heat in the heat dissipation medium to the surrounding environment. An exhaust mechanism 8 is provided on the third panel. The exhaust mechanism 8 can be a structure such as a heat dissipation louver. The function of the air guide 24 is to discharge the air discharged from the air outlet out of the cabinet 1 through the heat dissipation louver. As for the specific structure of the air guide 24, there can be many forms, as long as it ensures that the air discharged from the air outlet can be discharged from the exhaust mechanism 8.

Based on the above embodiments, in this application, the liquid-cooled host 2 is placed at the top or bottom of the cabinet 1, and at the same time, the air flow direction of the air outlet of the liquid-cooled host 2 is changed through the guide 24, so that the air discharged from the air outlet is discharged from the cabinet 1. The third panel is discharged, and the air is discharged outside the cabinet 1, thereby dissipating the heat in the heat dissipation medium to the surrounding environment, realizing the cooling of the heat dissipation medium, and facilitating the subsequent cooling work of the heat dissipation medium. The third panel is located between the first panel and the second panel. At the same time, when the liquid-cooled host 2 is located on the top of the cabinet 1, the third panel can be the top plate of the cabinet 1, thereby guiding the air to flow upward; when the liquid-cooled host 2 2 is located at the bottom of the cabinet 1, the third panel is the bottom plate of the cabinet 1, the bottom plate of the cabinet 1 and the ground form a heat dissipation space, and the air guide 24 guides the air to be discharged from the heat dissipation space formed by the bottom plate and the ground. On this basis, since cabinet 1 does not need to have ventilation holes or heat dissipation spaces at the rear end and both sides, when multiple energy storage cabinets are paralleled, due to the unique air outlet design, the energy storage cabinets can be placed side by side or back to back. Close arrangement can greatly save product costs and land costs.

In this embodiment, a way of arranging the air guide 24 is provided, that is, the number of the air guide 24 is one, the air guide 24 is located on the air outlet, and the air guide 24 only needs to conduct air guided by the air outlet.

An air duct is formed between the parts 24 to facilitate air circulation, and the ends of the two guide parts 24 facing away from the air outlet are arranged at the front and rear ends of the exhaust mechanism 8, so that the air derived from the air outlet can be completely guided through the air duct. Then, the air is discharged from the outside of the cabinet 1 from the exhaust mechanism 8 on the third panel.

The main function of the liquid cooling host 2 is to provide heat dissipation function for the heat dissipation medium. Therefore, the liquid cooling host 2 is also provided with a liquid outlet 22 and a liquid inlet 21. The heat dissipation medium with heat enters the liquid cooling host through the liquid inlet 21. 2, and uses air cooling to take out the heat in the heat dissipation medium, and the heat dissipation medium is discharged from the liquid outlet 22 to provide necessary conditions for the next cooling.

It should be noted that in order to ensure the heat dissipation effect of the liquid-cooled host 2 and ensure its stable air flow, the liquid-cooled host 2 is set in a separate first compartment inside the cabinet 1, so that the liquid-cooled host 2 is The air only moves along the ventilation direction of the liquid-cooled host 2, thereby improving the stability of the air flow and ensuring the heat dissipation effect.
