Description
Technical field
The utility model relates to a kind of cleaning high-energy power batteries, belong to power battery technology field.
Background technique
The temperature regime of power battery when in use is very big on the influence of its performance, and such as under high temperature environment, power battery exists
In charge and discharge process and hot environment using when can release a large amount of heat, if radiating condition difference will will lead to battery temperature and surpass
Height, risk increase, it is therefore desirable to have preferable heat dissipation performance；And at low ambient temperatures, especially in cold winter, move
Power battery working performance is very poor, or even is unable to operate normally because of low temperature, needs to keep the temperature battery again at this time.
Further, since the demand of heat dissipation, can be sometimes arranged on the corresponding box plate in airtightless space domain of Battery case
Ventilation hole, but simple ventilation hole is easy dust stratification again, is unfavorable for the cleannes setting of Battery case.
Utility model content
The purpose of this utility model is to provide a kind of cleaning high-energy power batteries, the specific scheme is that
A kind of cleaning high-energy power battery, including cabinet, cabinet is interior to be equipped with battery component, and the both ends of the cabinet, which are equipped with, opens
Mouthful；The battery component includes battery pack and cooling mechanism, and cooling mechanism includes the thermal transfer plate being folded between battery pack, heat
Conductive plate is through to the both ends of cabinet, and connect with the radiating piece that tank ends are arranged in；The radiating piece includes internal layer heat dissipation
The outside of plate and outer layer heat sink, outer layer heat sink is equipped with partition, the thermal transfer plate and internal layer heat sink and outer layer heat sink
It is fixedly connected, partition is movably set on the outside of outer layer heat sink；Phase is folded between the outer layer heat sink and internal layer heat sink
Become reservoir, thermal expansion item is connected between the partition and outer layer heat sink；Partition is equipped with outer layer heat sink and mutually staggers
Ventilation hole.
Further, the thermal transfer plate is hollow plate, and the inner hole of thermal transfer plate is through to the ventilation of outer layer heat sink
Hole.
Further, the thermal expansion item is polyvinylidene fluoride alkene plastics.
Further, the outer layer heat sink and partition are equipped with mutual corresponding groove, and the thermal expansion item is located at groove
It is interior.
The beneficial point of the utility model is: the power battery of this programme is equipped with cooling mechanism, the heat dissipation way of cooling mechanism
Diameter is the heat transfer that is generated battery pack by thermal transfer plate to tank ends, the phase between internal layer heat sink and outer layer heat sink
Become reservoir and can absorb heat, plays temperature adjustment effect.In addition, driving partition is mobile, partition after thermal expansion expanded by heating
Ventilation hole between outer layer heat sink is opened, and heat can be shed by ventilation hole.It thermally expands item and selects polyvinylidene fluoride alkene plastics,
Obvious expansion more than temperature 60 C will be generated, therefore ventilation hole only can just be opened in battery using adstante febre, and in deactivated shape
It under state, is bonded between partition and outer layer heat sink, ventilation hole is mutually closed, and dust can be prevented to enter, can also gas in winter
Temperature reaches heat insulation effect when low.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is that the utility model removes the side schematic view after rigid support plate.
Specific embodiment
Conventional ABS plastic knot can be used in a kind of cleaning high-energy power battery as shown in Figure 1, including cabinet 1, cabinet
Structure, the both ends of the cabinet are equipped with opening, are equipped with battery component in cabinet；The battery component includes battery pack 2 and heat dissipation machine
Structure, cooling mechanism include the thermal transfer plate 3 being folded between battery pack, and thermal transfer plate 3 generally uses aluminum, good heat conduction effect.
Thermal transfer plate is through to the both ends of cabinet, and connect with the radiating piece that tank ends are arranged in；The radiating piece includes that internal layer dissipates
The outside of hot plate 4 and outer layer heat sink 5, outer layer heat sink 5 is equipped with partition 6, the thermal transfer plate and internal layer heat sink and outer layer
Heat sink is fixedly connected, and partition is movably set on the outside of outer layer heat sink；It is pressed from both sides between the outer layer heat sink and internal layer heat sink
Equipped with phase-change thermal storage layer 7, thermal expansion item 8 is connected between the partition and outer layer heat sink；Partition is equipped with outer layer heat sink
The ventilation hole 9 mutually staggered.In addition, partition should select the material with thermal insulation property, such as with the plastic plate of foam inner liner.
In above scheme, the effect of thermal expansion item 8 is that driving partition is mobile relative to outer layer heat sink, due to partition and outside
The ventilation hole of layer heat sink is mutually staggered.As shown in Fig. 2, when thermal expansion item is in normal temperature state, partition and outer layer heat sink
Fitting, ventilation hole occlude one another.In thermal expansion expanded by heating, partition is squeezed to be deviated outward, with outer layer heat sink
Between generate spacing, ventilation hole between the two is to realize perforation.Therefore, the material selection for thermally expanding item, which should have, is closing
Apparent volume expansion is generated under the conditions of suitable temperature, to meet the driving force request of diaphragm displacement.
Kynoar is a kind of high polymer, and linear expansion coefficient is smaller at room temperature, and at 50 DEG C or more, line expansion
Coefficient significantly increases.Therefore, Kynoar is selected to can satisfy above-mentioned want as the material of thermal expansion item in the present embodiment
It asks.
To improve heat-transfer effect, as improvement project, the thermal transfer plate 3 is hollow plate, and the inner hole of thermal transfer plate passes through
It wears to the ventilation hole of outer layer heat sink.When the ventilation hole of partition and outer layer heat sink is opened, hollow thermal transfer plate is conducive to sky
Air-flow is logical, is more advantageous to heat dissipation.
In addition, the outer layer heat sink and partition are equipped with mutual corresponding groove, the thermal expansion item is located in groove.Heat
The thickness of Expandable strip at room temperature should be consistent with the total depth of above-mentioned groove, thermally expands item in normal temperature state, it is ensured that every
Plate fits with outer layer heat sink.Thermal expansion item is specifically located at four edge of partition and outer layer heat sink.
