Break to adding air channel between heat sink 107 to blow, be admitted to the wind in air channel after the heating of heater 109 becomes hot blast by adding
Direction venting from air vent 117 on heat sink 107 to the second heat sink 107, in hot blast from heat sink 107 is added to the second radiating
, can be by Hot-blast Heating positioned at battery pack around here during the direction venting of plate 107.So wind is constantly drawn into plus heat sink
Air channel is to be heated between 107, and the hot blast obtained after being heated is further through the air vent 117 on heat sink 107 constantly to second
Heat sink venting, not only increases the efficiency of heating surface, while the also temperature difference effectively in reduction battery case 101, it is to avoid in battery case
Part reaches heating preset temperature and heater when stopping heating, and the temperature difference in battery case is still larger.The battery pack of the application
Heat management device, which creatively solves Battery case in the prior art, needs good radiator structure and heating and thermal insulation structure
Conflicting requirements, it is ensured that the battery pack in battery system carries out charge/discharge operation in suitable environment, improves battery pack and follows
In the ring life-span, reduce all kinds of security risks caused by high/low temperature.
In summary, the application arranges to control in cooling by the arrangement of radiating element and the structure of optimization heat management
Temperature rise processed and the temperature difference, it is ensured that battery case and internal battery pack have effective and good air circulation, it is to avoid heat build-up is made
Into temperature rise, and significantly reduce the temperature difference of internal different parts；During heating, arrangement and heat by heater element
The structure of management arranges to heat and to being incubated in whole battery case battery pack.The radiator structure of the application is using warm
Amount guiding and the isolated inside air channel circulation cooling of heat, solve classification of waterproof such as IP67 and mutually conflict and phase with radiator structure
The problem of contradiction, solve with power consumption caused by intensive and a fairly large number of small heating film of arranging is larger and wiring complexity etc. is asked
Topic, the radiator structure of the application, relative to traditional liquid-cooling heat radiation structure, structural manufacturing process is simplified, and solves liquid-cooling heat radiation knot
Structure is complicated, and manufacture craft cost is high and is difficult to modular packing problem, and in the absence of the peace of liquid cooling structure coolant leakage
Full problem, is provided simultaneously with selective heating function.The mode of heating of the application, small power consumption, required heating film quantity is few, heating
Device is hardly damaged, while by the way of wind to be directly blown onto to fan ptc heater surface, overcomes PTC to after rated temperature
It is automatically stopped plus thermal property, drastically increases the efficiency of heating surface.The application is followed using inside and outside two layers of heat management, inside heating
Ring, during heating, thermal isolation film prevents to dissipate outside heat；External cooling is circulated, and is radiated in outer loop, and thermal isolation film prevents heat from entering
To internal layer battery pack.So, the structure that inside and outside two layers of heating and cooling are shared, it is ensured that the strict sealing that heating and thermal insulation needs
Characteristic, meanwhile, independent heat dissipating layer in turn ensure that cooling needs to dissipate thermal property, and thermal isolation film effectively prevents heat from returning to internal layer
Battery pack in, solve at the same realize heating and cooling two functions contradiction.It should be noted that in one embodiment,
Here internal layer refers in the battery case 101 for being by the first heat sink 103, the second heat sink 105 and the sky for adding heat sink 107 to surround
Between, outer layer refers to the wind of the first heat sink 103, the second heat sink 105 and the evagination formation relative closure of the inwall of battery case 101
Road.
Use above specific case is illustrated to the present invention, is only intended to help and is understood the present invention, not to limit
The system present invention.For those of ordinary skill in the art, according to the thought of the present invention, above-mentioned embodiment can be carried out
Change.
