Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation structures of energy storage boxes, in particular to a heat circulation acceleration structure for energy storage batteries. Background Art

[0002] The energy storage box is a grid-side outdoor smart substation based on the concept of "standard power distribution". It consists of chargers, inverters, batteries, isolation transformers, switches and other components, and can convert DC power into AC power.

[0003] There are usually multiple energy storage batteries installed in the energy storage box. When the energy storage box is in use, the energy storage batteries will generate a lot of heat. The energy storage box uses a carbon dioxide refrigeration cycle to achieve cooling and heating inside the battery pack. However, the heat generated by the energy storage batteries when they are running in a concentrated manner is large, and the heat inside the energy storage box is large. The exchange rate between the hot air in the box and the cold air outside is slow, which affects the heat dissipation effect of the energy storage battery. Therefore, a heat storage battery heat cycle acceleration structure is needed to solve the above problems. Summary of the invention

[0004] The purpose of the utility model is to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

Through the design of the inverted triangle protrusion at the bottom end of the protective plate, the hot air sucked out by the suction fan can be guided and diverted.

[0009] Preferably, two baffles are installed inside the heat box, and the two baffles are symmetrically arranged. Through the design of the two baffles, particulate debris can be guided and intercepted, thereby reducing the probability of particulate debris entering the box.

[0010] Preferably, a dustproof plate is embedded in the through groove on the right side of the box body, and a side guard plate is connected to the top side of the box body, and the vertical section of the side guard plate is an L-shaped structure. The dustproof plate is inserted into the through groove of the box body to prevent debris in the air from entering the box body through the dustproof plate.

[0011] Preferably, the fixing assembly includes a buckle plate buckled on the right side of the box body, and two locking components are symmetrically installed at the upper and lower ends of the right side of the buckle plate. The right side of the box body can be closed by buckling the buckle plate to cover the right side of the box body.

[0012] Preferably, the locking component includes a threaded shaft rotatably mounted on the side of the box body, and the threaded shaft is inserted into the inside of the constraint block through a groove, the constraint block is connected and fixed to the buckle plate, a screw cap is threadedly sleeved on the outer side of the threaded shaft, the bottom ends of the two threaded shafts are connected and fixed by a connecting rod, and the screw cap is threadedly sleeved on the surface of the threaded shaft, so that the screw cap is buckled on the bottom end of the constraint block, thereby ensuring the stability of the buckle plate and the box body.

[0013] The utility model has at least the following beneficial effects:

[0014] By setting up a suction component, the heat of the energy storage battery can be sucked and replaced. Compared with the traditional structure, the device allows the hot air mass to pass through the connecting shaft tube and enter the heat box. At the same time, the suction fan is started to suck the hot air mass gathered in the heat box. The hot air mass can be discharged from the outlet pipe during the suction, thereby accelerating the heat exchange rate inside the box and improving the heat dissipation effect of the energy storage battery.

[0015] By setting up a dustproof plate and a fixing component, the dustproof plate can be easily replaced. The device is designed with air permeable grooves on both sides of the box body, so that when the hot air mass in the box body is extracted, the external cold air mass can enter the box body through the air permeable grooves for filling. At the same time, the dustproof plate can intercept dust. The dustproof plate can be removed from the right side of the box body by removing the buckle plate, and then the dustproof plate can be replaced in time to prevent dust from being electromagnetically adsorbed on the battery surface during the heat exchange process, affecting the heat dissipation effect of the battery.
