Embodiment
Below in conjunction with accompanying drawing self cool battery pack of the present utility model is further described in detail.
As shown in Figure 1, the battery 1 that the utility model adopted has two lugs for having certain thickness flat lithium ion battery on its top: be anode ear 2 and negative electrode lug 3, all have a circular mounting hole 11 on each lug.
As shown in Figure 2, for superscribing the battery schematic diagram of phase-change material.Four sides and the bottom surface of described battery 1 all superscribe phase-change material layers 6, with resilient nylon rope 7 phase-change material layers 6 are fixed on the battery 1 again.Phase-change material has played protective effect to battery, can prevent that battery in use is subjected to mechanical damage.
From the chemical composition classification, phase-change material can be divided into inorganic phase-changing material and organic phase change material.The inorganic matter that can make inorganic phase-changing material comprises hydrated inorganic salt, inorganic salts, metal and alloy, wherein have only inorganic hydrated salt belong in, the low temperature phase change energy storage material.Compare with organic phase change material that its conductive coefficient, heat of fusion, density and storage density are all big, chemical property generally is neutral, low price.Phase-change material layers 6 in this example is mixed by inorganic hydrated salt and additive, and this phase-change material is used net purchase from Chinese phase-change material and got, and is a kind of nontoxic, not flammable, non-corrosive environment-friendly products.Phase-change material has very big potential, when phase-change material from solid-state when becoming liquid state (fusing), phase-change material absorbs a large amount of latent heat; When phase-change material becomes solid-state (freezing) from liquid state, phase-change material discharges a large amount of latent heat and plays effect at transformation temperature constant temperature.
This phase-change material can repeat the ten hundreds of phase variable period of work and not change its chemical property.The phase transition temperature of this phase-change material is 29 ℃, and this temperature is battery operated ideal temperature, and it has very high energy density (latent heat), and 26 ℃ to 32 ℃ operating temperature ranges, 1 liter of PS29 phase-change material latent heat energy equals the latent heat energy of 12 literss of water.
As shown in Figure 3, for being used to connect the connector shape of battery pole ear.Described connector 5 is the strip copper bar, and the lower end of this connector is provided with an inner groovy that is used to hold anode ear or negative electrode lug, is provided with the through hole 10 that is connected with lug on this inner groovy, also is provided with binding post 12 on connector.
As Fig. 4, shown in Figure 5, this example draw together 7 batteries 1 and 1 battery case 4 that the top is provided with positive and negative lug from the cold mould battery pack, on the outer wall of each battery 1, wrap up a phase-change material layers 6 earlier, by nylon rope 7 phase-change material layers is fixed on the battery 1 again, the positive and negative lug of battery does not wrap up into, stays the outside and does connection usefulness, because phase-change material layers 6 is thinner, and be close on the battery outer wall, therefore can not have influence on the assembling of whole battery group.After anode ear 2 bendings with all batteries 1, by behind the installing hole 11 on through hole on the screw bolt passes connector 5 10 and the anode ear 2 anode ear 2 of all batteries 1 being fixed on the positive pole of this battery pack of formation on a connection piece 5; Same, after negative electrode lug 3 bendings with all batteries 1, all negative electrode lugs 3 are fixed on the negative pole that forms this battery pack on another connector 5 by bolt, respectively be provided with a binding post 12 on two connectors 5: be installed in the positive terminal that is called on the connector 5 of affixed anode ear, be installed in the negative terminal that is called on the connector 5 of affixed negative electrode lug, can realize connection in series-parallel between each battery module by this positive and negative electrode binding post.This battery module is fixed in the battery case 4 by battery separator 8, this battery separator is the riser that the lower end has the right angle bending, and the outside of outmost two batteries is adjacent to mutually in the riser of described battery separator and the battery module, its lower end bending is provided with the circular hole that is connected with the battery case base plate.Battery case 4 for the cube of upper end open, it is made of the perpendicular base plate of four side plates and and side plate.
Operation principle of the present utility model is: battery pack temperature in charge and discharge process will raise, and when temperature arrived 29 ℃, phase-change material layers 6 began fusing.The working temperature of phase-change material layers 6 and each battery 1 rests on 29 ℃ (both having made battery pack ambient temperature all around on 29 ℃) all the time and melts fully up to phase-change material layers 6.In the gap of battery set charge/discharge, the temperature of each battery 1 will reduce, and when temperature falls to below 29 ℃ the time, phase-change material layers 6 begins to solidify.During this process, the working temperature of phase-change material layers 6 and each battery 1 will rest on 29 ℃ up to the phase-change material full solidification.This period of change constantly repeats every day, can effectively keep reaching the time more than 10 years.In addition, phase-change material layers 6 does not need to do regular maintenance, though during the periodic testing battery group still without any need for maintenance, easy to use, the heat radiation cooling effect good.
Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to the foregoing description, those of ordinary skill in the field are to be understood that: still can make amendment or be equal to replacement embodiment of the present utility model, and do not break away from any modification of the utility model spirit and scope or be equal to replacement, it all should be encompassed in the middle of the claim scope of the present utility model.
