Abstract
The utility model discloses a kind of radiator structure of energy-density lithium ion battery bag, comprise battery battery core, insulator, heat conduction thin plate and power brick heat conduction shell, between described battery battery core and heat conduction thin plate, be provided with insulator; Described heat conduction thin plate one end is upwards turned up and is fixedly connected with described power brick heat conduction shell; Separate by means of only one deck thin insulator between heat conduction radiating sheet and battery battery core, in conjunction with closely enabling heat fully conduct, thus can dispel the heat faster, also a saving space in addition, improve the volumetric specific energy of power brick; Heat conduction radiating sheet other, while tightly fit with heat radiation aluminum hull thus combine, self is also radiating element, provides heat dissipation path to better heat conduction radiating sheet while provide enough strength support to fin.
Description
Technical field
The utility model relates to a kind of radiator structure of lithium ion battery bag.
Background technology
Operating voltage is high, specific energy is high owing to having for lithium ion battery, have extended cycle life, adapt to the features such as operating temperature range is wide, is all widely used in electric automobile, electric tool, UPS, energy-accumulating power station every field.In actual applications in order to reach the demand of various different voltage, power grade, usually needing multiple cell to carry out connection in series-parallel combination, then forming battery pack by multiple this connection in series-parallel.But heat is more easily accumulated when its operating time is longer or carry out high current charge-discharge, once the ventilation and heat condition of module is poor, very easily cause heating up uneven in each position in module, thus inhibit the performance of its performance, more serious meeting directly forms potential safety hazard, even causes battery detonation.
Utility model content
In order to overcome the poor radiation that existing lithium ion battery exists, easily piling up the problem of heat, proposing a kind of lithium ionic cell module radiator structure now, Homogeneouslly-radiating can be carried out to internal battery pack by the employing of radiator structure.
For realizing above-mentioned technique effect, the technical solution of the utility model is as follows:
A radiator structure for energy-density lithium ion battery bag, comprises battery battery core, insulator, heat conduction thin plate and power brick heat conduction shell, is provided with insulator between described battery battery core and heat conduction thin plate; Described heat conduction thin plate one end is upwards turned up and is fixedly connected with described power brick heat conduction shell.
Described insulator is epoxy resin board or epoxy resin thin film.
In described heat conduction thin plate and power brick heat conduction shell heat-conducting be in aluminium sheet, copper coin, graphene film any one or multiple.
Compared with prior art, the beneficial effect had is:
1, separating by means of only one deck thin insulator between the heat conduction radiating sheet set by the utility model and battery battery core, in conjunction with closely enabling heat fully conduct, thus can dispel the heat faster.Also a saving space in addition, improve the volumetric specific energy of power brick;
2, the utility model heat conduction radiating sheet is other while tightly fit with heat radiation aluminum hull thus combine, self be also radiating element while enough strength support is provided to fin, provide heat dissipation path to better heat conduction radiating sheet.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein: 1, heat conduction thin plate; 2, insulator; 3, battery battery core; 4, power brick heat conduction shell.
Embodiment
Fig. 1 is a kind of embodiment of the radiator structure of the utility model energy-density lithium ion battery bag, comprise heat conduction thin plate 1, insulator 2, battery battery core 3 and power brick heat conduction shell 4 to form, when assembling, comprising multiple power brick heat conduction shell 4 combination stacked, forming battery pack pattern, the radiator structure of single lithium ion battery bag is made up of heat conduction thin plate 1, insulator 2, battery battery core 3 and power brick heat conduction shell 4, insulator 2 is laid below heat conduction thin plate 1, battery battery core 1 is set below insulator 2, heat conduction thin plate 1 and battery battery core 3 are by insulator 2 interval and be fixed together, in the present embodiment, heat conduction thin plate and the preferred material of power brick heat conduction shell are aluminium sheet, copper coin, graphene film, other materials with identical effect are also in the range of choice of this material, and the material of insulator prioritizing selection is epoxy resin board or epoxy resin thin film, battery battery core 3 opposite side and power brick heat conduction shell 4 are fixed simultaneously, one end of heat conduction thin plate 1 is upwards turned up and with power brick heat conduction shell 4 by weld or bolt is fixed, described battery battery core is specific energy, volumetric specific energy reaches 150Wh/kg, 450Wh/dm respectively
3above square laminated structure, when battery battery core 3 works, produce heat, part heat is dispelled the heat by the conduction of power brick heat conduction shell 4, part heat conduction gives the heat conduction thin plate 1 separated by insulator, heat conduction thin plate 1 is connected with power brick heat conduction shell 4, heat dissipation path and the efficiency of battery battery core can be increased, the battery pack of multiple power brick composition can thus increasing heat radiation effect, reduce the live load of battery pack, simultaneously when battery battery core needs outside heat to carry out heat heating, heat conduction thin plate can be more effective, improve more heat rapidly to battery battery core, make battery operated can be more quick, stable.
In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
