Description

Battery box with air cooling structure

Technical Field

The utility model relates to a battery field, concretely relates to battery box with forced air cooling structure.

Background

A plurality of unit batteries are connected in series and parallel properly, and the requirements of various capacities and voltages can be met, so that the energy supply device is suitable for more and more energy supply occasions. At present, a plurality of unit batteries are loaded through the battery box, the battery box is placed on a special battery frame, and the battery frame can be provided with a plurality of battery boxes so as to form an energy storage device. Because the space of the battery box is limited, and in order to provide the energy density of the battery box, the number of the battery cells in the battery box is large, and therefore, the temperature of the battery cells easily exceeds the safe temperature, and therefore, a corresponding heat dissipation structure needs to be arranged, and the heat dissipation of the battery cells can be carried out in all directions.

The existing heat dissipation structure comprises air inlets formed in all side faces of a battery box body, an air channel is formed between electric cores, and a fan is arranged on one side face of the battery box and used for exchanging air inside and outside the battery box. Because of all sides of the battery box are provided with the air inlets, the air fluidity in the battery box is poor, and the surface of the battery core cannot be fully cooled.

SUMMERY OF THE UTILITY MODEL

The utility model provides a battery box with forced air cooling structure, it is unreasonable to have solved the heat radiation structure among the prior art, leads to the problem that can not effectively reduce electric core temperature.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model provides a battery box with forced air cooling structure, includes the case board of U shape, case board top end opening part is equipped with the top cap, two openings parts that the case board is relative are equipped with panel and rear panel respectively, are equipped with ventilation fan on the rear panel, all the mirror image is provided with two sets of air inlet groups on the relative both sides face of case board, and the air inlet group includes the fresh air inlet that a plurality of rows set up along case board length direction, and every fresh air inlet that arranges all communicates with the forced air cooling passageway between two adjacent electric cores.

Furthermore, in order to make the air entering the chassis flow, each row of air inlet holes comprises a plurality of round holes and strip-shaped holes which are distributed at intervals. Because the opening size in round hole and bar hole is different, the wind speed that passes round hole and bar hole is inconsistent, and then improves mobility.

Furthermore, in order to improve the flowability of air in the chassis, the number of each row of air inlet holes of the air inlet group is reduced in sequence along the length direction of the chassis board. Because the two groups of air inlet groups are arranged in a mirror image mode, preferably, the number of the air inlet holes in one row close to the symmetry line of the two groups of air inlet groups is the largest, namely, the number of the air inlet holes in each row is gradually reduced from the middle of the side surface of the chassis to the outer side, and the phenomenon that the flowability of air in the chassis is reduced due to the fact that too much air enters the chassis at the same time is avoided.

Further, each group of air inlet groups comprises three rows of air inlet holes, and the number of the air inlet holes of the three rows of air inlet holes is 2, 4 and 5 in sequence.

Furthermore, in order to effectively dissipate heat of all parts of the battery cell, the centers of the first air inlet holes of each row are all positioned on the same straight line parallel to the bottom surface of the case board.

Further, in order to fix the battery and dissipate heat of each surface of the battery, the battery box further comprises a battery cell support for installing a battery cell, a plurality of contact protrusions are arranged on two opposite side faces of the battery cell support along the height direction of the battery cell support, and a gap between every two adjacent contact protrusions is an air cooling channel. Every electric core all with two electric core support cooperations, the protruding contact of two electric core supports promptly, and then the many forced air cooling passageways of shape between the electric core.

Furthermore, in order to cool two rows of battery cells (each row of battery cells comprises a plurality of battery cells), two side faces of the battery cell support parallel to the side face of the case plate are provided with air cooling grooves. Two electric cores form the passageway of taking a breath of intercommunication a plurality of forced air cooling passageways through the forced air cooling groove, under the effect of scavenger fan, make the cooling air who gets into the forced air cooling passageway from the fresh air inlet flow out quick-witted case through the passageway of taking a breath to this guarantees that the flow direction of cooling air is correct and can effectively dispel the heat to electric core.

Compared with the prior art, the utility model, have following advantage: utilize the wind channel trend between the thermal distribution of the battery box and the battery, make the forced air cooling passageway between two adjacent electric cores all correspond a fresh air inlet, ensure to carry out effectual heat dissipation to every electric core, can reduce the temperature of quick-witted incasement by a wide margin to avoid the interior high temperature of quick-witted incasement to cause electric core thermal runaway to arouse the explosion of starting a fire. Each row of air inlet holes correspond to an air cooling channel, so that air entering from the air inlet holes directly flows to the surface of the battery, and the flowability of the air in the case is improved.
