Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 and 2, the utility model provides a lithium ion laminate battery becomes splint includes heat-conducting layer 1, binder 2, splint base member 3, insulating layer 4 from last to extremely in proper order, and wherein, heat-conducting layer 1 contacts electric core surface when being used for becoming.
Wherein, splint substrate 3 one side polishing is ground flat, and the another side has the unevenness of micron level, and heat-conducting layer 1 uses binder 2 to fix at splint substrate 3's plane, and heat-insulating layer 4 adopts reflection-type heat preservation thermal-insulated coating at the unevenness plane, and when the formation, refer to figure 3, the clamp is buckled two and is become splint closely, including heat-conducting layer 1 with electric core 5 contact, heat-insulating layer 4 (reflection-type heat preservation thermal-insulated coating) is outmost with the clamp contact.
In a preferred embodiment, the splint base 3 is made of toughened glass, one surface of the splint base is smooth and flat, the other surface of the splint base is polished by frosting to cause uneven surface, the heat conducting layer 1 is a heat conducting silica gel pad, the adhesive 2 is silica gel, and the heat insulating layer 4 (reflective heat insulating coating) mainly contains TiO2According to the reflective heat-preservation and heat-insulation coating, the heat-conduction silica gel pad is attached to the smooth surface of the toughened glass through the binder 2, and the reflective heat-preservation and heat-insulation coating is coated on the polished surface of the toughened glass. The utility model discloses the heat that produces when utilizing electric core to become improves table body temperature, has practiced thrift the energy, and temperature distribution is more even, has promoted the electrochemical performance of electric core.
The utility model discloses a theory of operation:
due to the difference caused by the early production process, during formation, the heat generated at different positions is different, so that the heating speed of partial points or areas is high, and as can be seen from fig. 4, the heat generated by the heating point a is quickly dispersed to other places according to the heat diffusion direction F1 by the heat conduction layer 1, so that regional overheating is prevented, and the temperature of other areas is increased. As can be seen from fig. 5, after the temperature of the heat conducting layer 1 and the clamping plate base body 3 near the cell heating point B rises, infrared rays are radiated outwards along the direction F2, diffuse reflection occurs at the heat insulating layer 4, and the generated infrared rays are reflected back to the heat conducting layer 1 along the direction F3 (see the heating point infrared radiation direction F2 and the infrared reflection direction F3), so that heat loss can be effectively reduced.
The above only be the preferred embodiment of the utility model discloses a not consequently restriction the utility model discloses a patent range, all are in the utility model discloses a conceive, utilize the equivalent structure transform of what the content was done in the description and the attached drawing, or direct/indirect application all is included in other relevant technical field the utility model discloses a patent protection within range.
