Energy storage container with heat radiation structure

Technical Field

The utility model relates to a lithium cell technical field indicates an energy storage container who possesses heat radiation structure very much.

Background

With the popularization and application of new energy sources such as solar energy, wind energy and the like, an energy storage technology is developed, and lithium batteries gradually become mainstream products of energy storage due to the advantages of high energy ratio, long service life, high rated voltage, high power bearing capacity, low self-discharge rate, light weight, environmental protection, basically no water consumption in production and the like.

In general, the energy storage container is placed in an external space and is easily directly irradiated by the sun, when solar radiation passes through the outer surface of the container, a part of the solar radiation is reflected by the outer surface of the container, and a part of the solar radiation is absorbed by the surface of the container; the absorbed light energy is internally converted into heat energy, so that the temperature of the internal space is increased; when the temperature rises to be very high (50-60 ℃), the service life of the battery cell is influenced.

For the thermal insulation of energy storage containers, a method of coating the outer surface of the energy storage container with a sun protection coating is conventionally adopted. However, the conventional method has the following disadvantages: because the sun-screening coating mainly reduces the absorption of the sun, but the heat caused by the direct sunlight is still accumulated continuously along with the increase of the time, the sun-screening coating only can slow down the time of the temperature rise and cannot effectively reduce the internal temperature.

Therefore, how to provide an energy storage container with a heat dissipation structure to achieve the effect of improving the heat insulation of the energy storage container becomes a problem to be solved urgently.

Disclosure of Invention

The to-be-solved technical problem of the utility model lies in providing an energy storage container that possesses heat radiation structure, realizes promoting the thermal-insulated effect of energy storage container.

The utility model discloses a realize like this: an energy storage container with a heat dissipation structure, comprising:

a case;

the radiating fins are arranged at intervals at the top end of the box body and are abutted against the top end of the box body; the lower end of the radiating fin is provided with a plurality of radiating grooves;

and the heat insulation plate is arranged at the upper end of the radiating fin in a suspended mode and covers the top end of the box body.

Further, the thickness of the radiating fin is smaller than 2 mm.

Further, the radiating fin is a copper sheet or an aluminum sheet.

Further, the heat insulation plate is arranged at the upper end of the radiating fin in a suspended mode through at least four supporting pieces.

Further, the heat insulation plate is a high-strength plastic plate or a metal plate.

Further, the upper surface of the heat insulation plate is coated with a reflecting layer.

The utility model has the advantages that:

the heat insulation plate is arranged in the air at the upper end of the radiating fin in a hanging mode and covers the top end of the box body, namely the radiating fins are arranged in the space between the box body and the heat insulation plate, the lower ends of the radiating fins are abutted to the box body, and gaps are reserved at the upper ends of the radiating fins; the direct solar radiation during the energy storage container, most solar radiation is fallen in the heat insulating board reflection, the coefficient of heat conductivity of the air between heat insulating board and the box is lower, transmits a small amount on the heat of box top transmits the fin again, because the thickness of fin is less than 2mm, and the lower extreme is equipped with a plurality of radiating groove, and big with the area of air contact, spreads out the heat rapidly under the environment of ventilating, and then very big promotion energy storage container's thermal-insulated effect.
