The following are specific names of each of the identifiers in the figure: 1. an upper cover; 2. an energy storage component; 3. a lower cover; 4. a heat radiation fan.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Referring to fig. 1-2, a novel battery pack device is composed of a housing and an energy storage component 2 arranged in the housing; a plurality of cooling fans 4 are uniformly arranged on the shell at intervals, and the cooling fans 4 are connected in series with a main control panel (not shown in the figure) arranged in the battery pack to provide electric operation for the cooling fans.
The electric core is provided with a thermistor, the thermistor senses the temperature change of air around the electric core, the operation of a cooling fan can be accelerated after the temperature of the air around the electric core is increased, the air exhaust quantity between the air is enhanced, and heat is taken away rapidly; the operation of the cooling fan can be slowed down after the temperature of the air around the battery core is reduced.
The shell comprises an upper cover 1 and a lower cover 3, and the energy storage component 2 is arranged between the upper cover 1 and the lower cover 3.
The heat radiation fan 4 is fixed on the lower cover 3, the heat radiation fan 4 is installed close to a thermistor arranged on the battery cell, and the thermistor regulates the rotating speed of the heat radiation fan 2 according to the temperature of air between the battery cells; the cooling fan 4 blows air into the energy storage component 2 to realize rapid convection of air in the energy storage component 2.
The cooling fan 4 may be integrally formed on the surface of the lower cover. Or may be individually and fixedly mounted on the surface of the lower cover 3.
As shown in fig. 2, the energy storage component 2 is formed by uniformly arranging a plurality of electric cores, and the electric cores are arranged in a honeycomb shape. The surface of the lower cover 3 is uniformly provided with a plurality of battery core jacks which are arranged in a staggered manner, and the battery cores are respectively and correspondingly inserted and installed in the battery core jacks. The periphery of the lower cover 3 is also provided with fixing holes for inserting the fixing columns 5, and the fixing columns 5 can strengthen the stabilizing effect of the battery cells.
The upper cover 1 correspondingly is provided with a plurality of positioning grooves, when the battery cells are respectively inserted into the lower cover 3, the upper cover is arranged on the top of the battery cells, and the periphery of the battery cells is fastened and installed with the fixed columns 5 through screws, so that the battery cells are very firmly installed between the upper cover 1 and the lower cover 3.
After the honeycomb-shaped battery cell is arranged between the upper cover 1 and the lower cover 3, fixing and reinforcing are carried out on the periphery through the fixing columns 5; the honeycomb cell arrangement can greatly save the overall size space of the energy storage component 2.
When the electric core is used, the power switch is started, the main control panel in the battery pack provides power for the cooling fan 4 formed by serial connection, so that the cooling fan can be operated immediately, the cooling fan 4 arranged on the surface of the lower cover 3 blows air into a gap between the electric cores to form air convection, so that heat generated by the electric cores in use can be timely emitted, and the electric cores are provided with the electric heating regulator, so that the rotating speed of the cooling fan can be regulated along with the change of temperature.
