Description
Technical Field
The utility model belongs to the technical field of the lithium cell, concretely relates to quick radiating lithium cell.
Background
Lithium batteries are widely used at present, and comprise a battery shell, electrolyte and other elements, wherein the battery shell is sealed by a cover sealed by metal glass, so that the electrolyte is stored in the battery shell in a vacuum manner. Because the lithium cell needs the charge of long-term circulation, when the pressure in the lithium cell was too big, the phenomenon that the lithium cell often can take place hollowly to warp, and this kind of condition generally takes place because the too high temperature of lithium cell in charging process leads to. Therefore, heat dissipation of the lithium battery needs to be considered in the using process.
Chinese patent CN206040864U discloses a lithium battery, is equipped with the coolant liquid in the control tank, carries out temperature control by the electrolyte of coolant liquid in to accommodation space, is equipped with the coolant liquid in the control tank, when the temperature of lithium battery was too high, carries out temperature control by the electrolyte of coolant liquid in to accommodation space, so prolonged the life of lithium battery. But do not improve current lithium battery case in the above-mentioned structure to lead to when the lithium cell lasts the work, when the heat of coolant liquid can't dispel the heat fast, can lead to the unable produced heat of lithium cell that absorbs of coolant liquid, thereby can't reach required radiating effect, lead to the unable radiating temperature of carrying out of lithium cell to rise.
SUMMERY OF THE UTILITY MODEL
To the problem of above prior art, the utility model provides a quick radiating lithium cell.
The utility model discloses an adopt following technical scheme to realize:
the utility model provides a quick radiating lithium cell, includes the shell, the shell is cylindrical, the shell includes mutual fixed connection's inner protective layer and outer protective layer, even interval embedding has a plurality of radiating blocks in the outer protective layer, the radiating block is including the extension bar, spring and the baffle of being heated, the extension bar one end of being heated is fixed in on the inner protective layer outer wall, the other end with baffle one end contact, spring one end is fixed in on the inner protective layer outer wall, the other end with baffle middle part fixed connection, the baffle other end with the outer protective layer is articulated.
And sealing rings are fixed at the edges of the periphery of the outer side of the baffle.
The utility model has the advantages that:
the utility model discloses simple structure can make the lithium cell dispel the heat fast through the radiating block. When the temperature of lithium cell rose, the extension pole that is heated gradually extended, with the ejecting outer protective layer of baffle one end to produce the heat dissipation through-hole on the outer protective layer, be convenient for distribute away the heat of lithium cell inside, the heat dissipation through-hole along with the extension of the extension pole that is heated and the grow, thereby can be according to the automatic radiating rate that changes of temperature. When the temperature of lithium cell reduced, the extension rod that is heated shortens gradually, retracts original length at last, and the baffle is got back to in the outer protective layer again under the pulling of spring this moment.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. the heat dissipation device comprises a shell, 2, an inner protection layer, 3, an outer protection layer, 4, a heat dissipation block, 5, a heated extension rod, 6, a spring, 7, a baffle, 8 and a sealing ring.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1, a quick radiating lithium cell, which comprises a housing 1, shell 1 is cylindrical, shell 1 includes inner protective layer 2 and outer protective layer 3 of mutual fixed connection, even interval embedding has a plurality of radiating block 4 in the outer protective layer 3, radiating block 4 is including being heated extension rod 5, spring 6 and baffle 7, 5 one end of being heated extension rod is fixed in on the 2 outer walls of inner protective layer, the other end contacts with 7 one end of baffle, 6 one end of spring is fixed in on the 2 outer walls of inner protective layer, the other end and 7 middle part fixed connection of baffle, the baffle 7 other end is articulated with outer protective layer 3.
And sealing rings 8 are fixed at the peripheral edges of the outer side of the baffle 7.
When the temperature of lithium cell rose, the extension pole that is heated gradually extended, with the ejecting outer protective layer of baffle one end to produce the heat dissipation through-hole on the outer protective layer, be convenient for distribute away the heat of lithium cell inside, the heat dissipation through-hole along with the extension of the extension pole that is heated and the grow, thereby can be according to the automatic radiating rate that changes of temperature.
When the temperature of lithium cell reduced, the extension rod that is heated shortens gradually, retracts original length at last, and the baffle is got back to in the outer protective layer again under the pulling of spring this moment.
