Specific embodiment
As shown in Fig. 1 to Figure 15, for existing defect, protection main body of the invention is as follows:
Exploitation is a kind of lithium cell power battery pack, and existing cylinder type lithium battery has two kinds of feelings during the installation process
Condition forms power battery pack one is directly being bundled using film material, this power battery pack the problem is that,
It is easy accumulation heat, causes temperature to increase, self-expanding, leakage, spontaneous combustion, self-destruction, safety is poor, existing for this problem
Solution is to increase a frame, and existing frame has thermal expansion and contraction still obvious, such as Chinese patent
The scheme announced in CN204927374U, wherein bracket uses moulding, has the function of insulating and position, can be convenient cylinder
The assembly of shape lithium battery, still, above-mentioned structure do not form air duct, and the heat dissipation of battery core is not solved fundamentally, and deposits
In following problems: bracket is plastic part, have inflammable characteristic, although plastic density is lower than metal, bracket be it is solid,
It is self-possessed larger, accounts for about 1/10th or so of battery core weight, in addition antidetonation sound insulation effect is also bad.
The technical problem to be solved is:
Problem one: during power battery work, there are heat expansion effect, the swell incremenies of multiple battery cores to be accumulated at for single battery core
In battery pack, huge deformation just will form, cause the dislocation of electrode position, current solution is that electrode design is at U
Type, for making up displacement and deformation between battery core.
Problem two: in the case that short circuit occurs for single battery core, due to what is be proximate between battery core, without bracket carry out every
From, and battery core and the material of busbar are lithium material, high temperature itself is inflammable, can cause the detonation of the battery core between adjacent.
Problem three: cooling wind is in unordered flow regime, cannot effectively be cooled down for battery core, cannot be in battery core
It is formed about uniform wind field, the non-uniform temperature at each battery core causes battery core internal resistance inconsistent, and power consumption increases.
Problem four, from great, lithium electricity battery core density itself is big, adds metal shell, be self-possessed bigger, self weight account for vehicle body from
More than half of weight.
Problem five, the costs of manufacture such as bracket, metal-back are high.
Based on the description above, cylinder lithium cell power battery assembly provided by the invention, and cool down to battery
Wind adjustment structure.
Power battery assembly includes shell 1, organic foaming bracket 2, corrugated sleeve 3, upper cover 5, lower cover 5 '.
Shell 1 uses moulding, is to be formed by the opposite installation of upper and lower two sub- shells, and use bolt fastening, internal
A rectangular space is formed, inside is for installing battery core.
Above-mentioned shell can also use thin sheet metal part.
Organic foaming bracket 2 is upper and lower penetrating structure, is made for resin expanded technique, using Mold Making.
Organic foaming bracket 2 is resin expanded block structure, is provided in the two sides of organic foaming bracket several
A open C-shaped groove 23 being evenly arranged is provided with supporting projections 24, several organic hairs at the open position of the C-shaped groove
Bubble bracket 2 is set side by side and forms several first circular holes 21, every one first circular hole between two adjacent organic foaming brackets
One corrugated sleeve 3 of middle insertion, the corrugated sleeve are the annulus column that metal plate is formed by corrugation, bending, each wave
