According to a battery pack which is produced by utilizing the battery pack shell, air is fed and discharged through the V-shaped spaces, so that the air inside the battery is circulated, the temperature difference of batteries in the battery pack can be reduced, and the service life of the battery pack can be prolonged.
Description
Technical field
The present invention relates to a kind of power brick housing.
Background technology
The arranging batteries support that current battery bag adopts is made up of two housings, the upper and lower sandwich construction of the many employings of battery module, air intake passage or air-out passage are arranged on the superiors or the orlop of battery module, when ventilation, need to pass through successively the battery module of each layer, so just cause the battery temperature difference of each layer of battery module larger, the battery temperature of the battery module of air inlet is low, the battery temperature of the battery module of air outlet is high, temperature distributing disproportionation is even, finally affects the useful life of power brick.
Summary of the invention
The present invention aims to provide a kind of power brick housing that is conducive to circulation of air, reduces the battery temperature difference.The present invention realizes by following scheme:
A kind of power brick housing, comprise shell, two above and identical inlet shell and air-out housings of quantity, the mid portion of inlet shell, the mid portion of air-out housing are all inclined-plane, and the inclined-plane of inlet shell mid portion with the inclined-plane of angle angle in direction perpendicular to inlet shell two ends and air-out housing mid portion with identical perpendicular to the angle angle in the direction at air-out housing two ends; Inlet shell and air-out housing complement one another and form several battery pack passages and mode adjacent with inlet shell and inlet shell, that air-out housing is adjacent with air-out housing and put side by side and fix in the enclosure, between adjacent inlet shell, form between the openend in QieVXing space, a V-arrangement space and shell and form air intake passage, between adjacent air-out housing, form between a V-arrangement space QieVXing space openend and shell and form air-out passage.
For obtaining better effect, the inclined-plane of described inlet shell mid portion with perpendicular to the angle angle in the direction at inlet shell two ends be 2～8 degree.
Compared with prior art, the present invention has the following advantages:
Power brick housing of the present invention, adopt the mid portion of inlet shell, air-out housing to be inclined-plane, inclined-plane have angle with perpendicular to the direction at inlet shell or air-out housing two ends and angle identical, make adjacent inlet shell or air-out housing form a V-arrangement space, and between the openend in the V-arrangement space that inlet shell forms and shell, leave space and form air intake passage, between the openend in the V-arrangement space that air-out housing forms and shell, leave space and form air-out passage.The power brick that adopts power brick housing of the present invention to make, air-flow enters from air intake passage, flows into the V-arrangement space of air intake passage end the battery pack on the both sides, V-arrangement space of flowing through, and flows out to air-out passage from the V-arrangement space of air-out passage end, discharge hot gas from air-out passage, so circulation; The flow direction of air-flow in power brick is stable, and air-flow does not need through multi-layer cell pack module, and air circulates, make the air flow rate of each battery pack in power brick more even, reduce the temperature difference between each battery in power brick, the useful life that can improve power brick.
