Abstract
The utility model discloses a radiating device of a battery pack, comprising a radiating shell, radiating fins arranged at the periphery of single batteries in the radiating shell, and an insulating heat-conducting piece which is connected among the radiating shell and the radiating fins in a heat-conducting manner. The radiating device can lead the heat of a plurality of single batteries which are radially arranged in a shell of the battery pack in parallel to be radiated fast, thus leading the temperature of the inner part of the battery pack to be even with fast radiating speed and high efficiency. The battery pack can realize omniseal, and has small occupied space and low use cost.
Description
Technical field
The utility model relates to a kind of battery pack heat abstractor.
Background technology
Battery pack generally comprises the some cells in shell and the shell, in use or when charging, each cell all can the evolution of heat, if the radiating effect of battery pack is weak, the accumulation of the heat of battery heating brings influence can for the use of battery pack, the life-span that might cause the unstable of battery pack and shorten battery pack.In order to help heat radiation, generally can be provided with louvre on the battery-pack exterior casing, circulate in battery pack by air and realize heat radiation.But such radiating rate is slow, and outside simultaneously dust impurity can enter by louvre, and making influences the easily dirty even corrosion of battery pack and use.
Summary of the invention
The utility model purpose provides a kind of battery pack heat abstractor, the heat transferred of a plurality of cells that it can be arranged in parallel the battery-pack exterior casing inner radial comes out to distribute fast, make that the battery pack internal temperature is even, radiating rate is fast, efficient is high, battery pack can realize hermetically sealed, and take up room little, use cost is low.
The technical solution of the utility model is: a kind of battery pack heat abstractor comprises heat-dissipating casing, is located at the fin around the cell in the heat-dissipating casing and heat conduction and is connected in insulating heat-conductive spare between heat-dissipating casing and the fin.Described insulating heat-conductive spare is an insulating heat-conduction material, as heat-conducting glue.
Further, in the gap of described fin between a plurality of cells that radially are arranged side by side, and contact with cell surface.With the heat transferred on cell surface to insulating heat-conductive spare.
Further, described insulating heat-conductive spare is fixed and is resisted against on the heat-dissipating casing inwall with the dismountable grafting of fin.Easy-to-dismount like this structure makes battery pack easy accessibility, maintenance simply.
Further, described heat-dissipating casing comprises hermetically sealed heat conduction shell.All-sealed structure can prevent effectively that dust and corrosive deposit from entering in the battery-pack exterior casing, pollutes or the damage cell.Described hermetically sealed heat conduction shell is a metal material, preferred aluminum alloy materials.
In addition, described heat-dissipating casing can also comprise the outer radiating part that is provided with on hermetically sealed housing and the hermetically sealed housing.This moment, hermetically sealed housing itself can heat conduction, also can not heat conduction.When the heat conduction of hermetically sealed housing own, outer radiating part can be for being located at the radiator structures such as radiating fin of hermetically sealed surface of shell.
Further, described outer radiating part can be water-circulating cooling device, and the heat that the battery pack internal delivery is come that water-circulating cooling device can be very fast is taken away, and radiating rate is fast.This moment, hermetically sealed housing can be a heat conductivility good metal shell, also can be not transcalent, as mould shell; If when moulding shell, heat conductive insulating spare does not directly contact with water-circulating cooling device hermetically sealed housing for transcalent, heat is imported in the water-circulating cooling device transfer away.
Described fin is metal material, preferably aluminum material.Metal material heat conduction is fast, and insulating heat-conductive spare is clipped between fin and the heat-dissipating casing, has both played the effect of fin and heat-dissipating casing mutually insulated that makes, prevents that electric leakage is dangerous, can help heat radiation with the heat transferred on the fin to heat-dissipating casing again.
The utility model advantage is:
1, the utility model can be rapidly with the heat transferred between the inner cell of battery pack to shell and distribute, prevent excessively accumulation and cause hidden danger safe in utilization or shorten battery pack useful life of heat in battery set.
2, the utility model adopts insulating heat-conductive spare to be connected between fin and the heat-dissipating casing, insulating heat-conductive spare respectively and the contact-making surface between fin and the heat-dissipating casing big, the convenient heat transfer, simultaneously, when fin and heat-dissipating casing all are conductive material, insulating heat-conductive spare can be the insulating heat-conductive material, plays insulation and conductive force between fin and the shell.
3, the utility model heat-dissipating casing surface can be provided with water-circulating cooling device, and compares by battery surface air flows heat radiation, and water-cooling is rapider effectively, and is subjected to the influence of ambient temperature little, and the heat in the more convenient heat-dissipating casing spreads out of.
