Technical field
The present invention relates to the battery thermal management field, particularly contain the Luftgekuhlte rotierende batteries of electric automobile heat management device of phase-change material.
Background technology
Battery is one of core component of electric automobile and hybrid vehicle, its performance quality directly has influence on the performance of electric automobile and hybrid vehicle, yet be subjected to the restriction of technical conditions, the performance of electrokinetic cell is difficult in big breakthrough in a short time, if make electric automobile obtain commercial applications, just must guarantee that battery works under optimal conditions, to improve its service behaviour, life-saving.The electrokinetic cell bag that uses on the electric automobile is made up of by series-parallel system a plurality of battery modules, all can produce heat in the battery charge and discharge process, thereby make the power brick bulk temperature raise, and temperature can have a strong impact on battery performance and life-span when too high, even can directly cause battery failure.Simultaneously, when discharging and recharging, the heat release in each single pond or the inhomogeneous meeting of dispelling the heat cause occurring in the power brick temperature difference in the power brick, and the higher cell degradation of local temperature is very fast, and long-play can destroy the consistency of battery pack, thereby battery pack was lost efficacy.On the other hand, when battery was worked at low temperatures, cell voltage and discharge capacity can reduce significantly, and temperature is low to a certain degree, may cause electric motor car to start or normally to travel.Battery carried out effective heat management, make power brick when work that its interior temperature distribution is even, and entire cell bag temperature maintenance is in the optimum working temperature scope of battery, to improve battery performance, extending battery life is most important.So it is significant to applying of electric automobile and hybrid vehicle to develop high performance battery thermal management system.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, propose a kind ofly can maintain the Luftgekuhlte rotierende batteries of electric automobile heat management device that contains phase-change material in the optimum temperature range to battery temperature.
The present invention adopts following technical scheme:
A kind of Luftgekuhlte rotierende batteries of electric automobile heat management device that contains phase-change material, comprise battery case, a plurality of interconnective batteries are set in the described battery case, described battery outer wall is with interlayer, the inner casing of described interlayer and the outer wall of battery are fitted, filling porous medium between the Inner of interlayer shell and shell is filled phase-change material in the hole of described porous media.
On the described interlayer shell radiating fin is set.
Described porous media is made by copper or aluminium.
Described radiating fin is a kind of in plate, Wave plate shape or the triangle corrugated plate type.
The course of work of the present invention:
The heat that battery distributes by heat conduction pass to interlayer inner casing, pass to shell by the porous media skeleton in the interlayer, distribute by the mode of radiating fin with air cooling at last, battery steady operation time institute liberated heat under certain load can dissipate by above-mentioned heat-conducting mode, and battery temperature remains in the optimum temperature range; When battery load was unstable, the heat that battery produces also can change fast, and at this moment the phase-change material of filling in the porous media hole can the absorption portion heat, and battery temperature is still maintained in the optimum temperature range.
Beneficial effect of the present invention:
(1) be filled with the interlayer of porous media and phase-change material, not only good heat conductivity but also heat storage capacity are strong, can guarantee that internal temperature of battery evenly distributes, and can guarantee that battery temperature maintains in the optimum working temperature scope;
(2) interlayer good airproof performance can prevent effectively that phase-change material from causing damage to corrosion or the phase-change material leakage of battery to battery;
(3) on the shell of interlayer radiating fin is set, radiating fin can adopt flat board, waveform, triangle corrugated etc., can the enhance heat effect;
(4) in the battery case, the radiating fin on the interlayer shell of all batteries connects together, and battery is had good fixation.
