Technical Field

The utility model relates to a lithium cell installation technical field specifically is an intelligent heat dissipation outage device of lithium cell.

Background

The lithium battery is gradually applied to various fields of daily life as a power battery, particularly the rise of the electric automobile industry in recent years, and the demand and application scenes of the lithium battery are greatly increased; the heat dissipation of the lithium battery is still a technical difficulty so far, and the application of the lithium battery is influenced to a great extent.

At present, two modes of air cooling and liquid cooling are mostly adopted for heat dissipation of the lithium battery, wherein the liquid cooling is complex in structure, higher in cost and lower in safety factor during use; the air cooling structure is simple and high in safety, but the cooling effect is poor.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an intelligence heat dissipation outage device of lithium cell to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: an intelligent heat dissipation power-off device of a lithium battery comprises: casing, lithium cell piece, temperature switch, output line, the casing constitute by shell body and interior casing, the shell body all is the square hollow casing of platykurtic with interior casing, and interior casing setting is in the inside of shell body, and adopts the connection of heat dissipation connection fin between shell body and the interior casing to be connected, heat dissipation connection fin evenly be provided with the multiunit, space formation air flow channel between the adjacent heat dissipation connection fin, the lithium cell piece pass through the inside of heat conduction colloid rigid coupling at interior casing, the output line pass the corresponding through-hole of shell body and interior casing respectively, and the output port electric connection of output line and lithium cell piece, temperature switch pass through the heat conduction colloid rigid coupling on the through-hole of shell body, and temperature switch and output line electric connection.

Further, the casing be provided with a plurality ofly, a plurality of casings stack the setting, and adopt thermal-insulated colloid to connect between two adjacent casings, the lithium cell piece parallel connection in every casing inserts power supply circuit.

Furthermore, the shell is made of copper-aluminum alloy materials or heat dissipation ceramic materials.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a lithium cell intelligence heat dissipation outage device, at first adopt the high heat conduction material to make the casing, wherein the casing divide into shell body and inner shell, adopt heat dissipation connection fin connection between shell body and the inner shell, and the lithium cell piece passes through the inside of heat conduction colloid rigid coupling at the inner shell, just formed the passageway that supplies the circulation of air between the heat dissipation connection fin, just can dispel the heat of casing through the fan heat piece is bloated the air flow, the radiating effect is good; in addition, be connected with temperature switch through heat conduction colloid on the shell body, when the casing temperature was too high, temperature switch then cut off the output line of lithium cell piece, the lithium cell piece stops electric power output, the temperature just can descend fast, when the temperature reduces below the threshold value, temperature switch then switches on the output line of lithium cell piece, the lithium cell piece carries out electric power output again, the alternating work and the heat dissipation of carrying out of a plurality of parallelly connected lithium cell pieces that set up, can not influence holistic electric power output, the result of use of lithium cell has been improved greatly.

The utility model has the advantages of simple structure, convenient use, good use effect and the like.
