Description
Technical field
The present invention relates to lithium-ion-power cell technical field of heat dissipation, specifically a kind of lithium-ion-power cell with radiator structure.
Background technology
Along with advocating of Green Travel idea, the environment-friendly function of green traffic instrument---electric automobile highlights day by day.But electric automobile operationally, module heating is serious, temperature rise is too fast, if can not dispel the heat the stability and the life-span shortening power battery pack that will affect power battery pack in time.Chinese patent application CN103700904A adopts heat transfer rod to be directly conducted to outside housing by the heat in power battery pack gap; Heat distributes by Chinese patent application CN101047274A employing collecting plate passage, heating panel passage and the cooling fluid recycled; Chinese patent application CN101771180A carries out radiating and cooling by compressed air to power battery pack.All these cooling measures are all the heat that power battery pack produces directly is transmitted to the external world and underuses; In addition, the heat dissipation problem of power battery pack is finally summed up as the heat dissipation problem of cell, and therefore, the radiating efficiency improving cell is the key solving power battery pack heat dissipation problem.
Summary of the invention
The object of the present invention is to provide a kind of lithium-ion-power cell with radiator structure, set about from cell the radiating efficiency and the energy regenerating utilance that improve power battery pack.
Technical scheme of the present invention is:
A kind of lithium-ion-power cell with radiator structure, comprise battery shell layer, described battery shell layer is aluminum hull layer, also comprise the heat radiation shell be prepared from by thermoelectric material, described radiation shell laminating invests battery shell layer outer surface, and described heat radiation shell is connected with automobile-used load, forms radiated energy and reclaim loop.
Have a lithium-ion-power cell for radiator structure, comprise battery shell layer, described battery shell layer is the heat radiation shell be prepared from by thermoelectric material and aluminum compound, and described heat radiation shell is connected with automobile-used load, forms radiated energy and reclaims loop.
The described lithium-ion-power cell with radiator structure, described radiated energy is reclaimed loop and is directly formed by connecting by wire with automobile-used load two ends respectively by the shell that dispels the heat meaning two place of taking up an official post.
Beneficial effect of the present invention is:
As shown from the above technical solution, the present invention directly sets about from cell, its heat dissipation problem is solved from root, effectively reduce the heating up problem of cell, improve cycle life and the security performance of cell, utilize the Seebeck effect of thermoelectric material to carry out thermo-electric generation, the converting heat that cell produces becomes electric energy to be directly supplied to automobile-used load use by the loop of structure, secondary utilization can be carried out, energy-conserving and environment-protective more to used heat.
Accompanying drawing explanation
Fig. 1 is example sketch of the present invention, and wherein, 1-dispels the heat shell, and 2-radiated energy reclaims loop, the automobile-used load of 3-.
Embodiment
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of lithium-ion-power cell with radiator structure, there is the heat radiation shell 1(be prepared from by thermoelectric material and aluminum compound and instead of existing aluminum hull layer), heat radiation shell 1 and the existing load on automobile-used load 3(vehicle) be connected, form radiated energy and reclaim loop 2, this radiated energy reclaims loop 2 and can to dispel the heat on shell 1 from cell and any two draw wires and be connected directly between automobile-used load 3 two ends.Thermoelectric material adopts known thermoelectric material.
The heat produced in lithium-ion-power cell charge and discharge process can make shell temperature raise, the Seebeck effect of thermo-electric generation makes thermoelectric material be equivalent to temporary source, designed by foregoing circuit, the electric current of thermo-electric generation can be directly acted on automobile-used load two ends and realize secondary utilization.The used heat produced in cell charge and discharge process is not only directly changed into power cycles and utilizes by the present invention, and significantly reduces the heating up problem of cell, and then improves cycle life and the security performance of lithium-ion-power cell.
Testing example: choose ternary battery, ternary material is Li (Ni
0.5co
0.2mn
0.3) O
2to (aluminium and thermoelectric material are composited) ternary battery five of heat radiation shell be had and module, with after 0.33C charging under room temperature, then discharge with 0.5C, 1C, 2C, 3C respectively, the peak temperature of battery case and inside under record discharge time and multiplying power discharging condition, concrete data are as shown in table 1.
Test comparison example: choose ternary battery, ternary material is Li (Ni
0.5co
0.2mn
0.3) O
2, will have the ternary battery five of conventional aluminium shell and module, with after 0.33C charging under room temperature, more respectively with 0.5C, 1C, 2C, 3C electric discharge, the peak temperature of battery case and inside under record discharge time and multiplying power discharging condition, concrete data are as shown in table 2.
As can be seen from Table 1 and Table 2, there is the ternary five of heat radiation shell (aluminium and thermoelectric material are composited) and module compared to the ternary five with conventional aluminium shell and module discharge time is longer, peak temperature is lower, benefit from the thermoelectric material composition in heat radiation shell, heat energy is directly changed into utilization of power, extend the battery modules operating time, reduce its working temperature.
The above execution mode is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection range that claims of the present invention determine.
