Description
Technical field
The present invention relates to a kind of priming system thermoelectricity pool technology.
Background technology
At present, fitted outside thermal cell is main is tied three parts and is constituted by battery cover, band temperature keeping battery shell, battery, side insulation
Standard order is glass layer and asbestos perithallium.At present, the fitted outside thermal cell of volumetric specific power 735.5W/L is present
Following problem：
1) low-temp activation time 0.45s~0.47s, compared with technical requirements≤0.5s, nargin is small.
2) heat sets low, and low-temperature working time scattered error is big；Heat sets high, and hot operation time scattered error is big.
3) the low-temperature working time be put to the test frock influence it is larger.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention to provide a kind of fitted outside of volumetric specific power (>=735.5W/L) high
Thermal cell side insulation construction, the low-temp activation time is short, and thermal cell heat sets and interval may be selected greatly, and the low-temperature working time is difficult
The frock that is put to the test influences.
The technical solution adopted for the present invention to solve the technical problems is：A kind of side insulation knot of fitted outside thermal cell
Structure, including asbestos perithallium, heating perithallium, glass fibre perithallium, heating plate and the bar I that ignites, ignite bar II.
In the battery case of fitted outside thermal cell, battery bundle lateral wall coats asbestos perithallium, heating perithallium, asbestos and encloses successively
Layer and glass fibre perithallium；Battery bundle top coats the bar I that ignites；Battery bundle bottom coats ignite bar II, heating plate and nothing successively
Hole asbestos；Described ignite the connection ignition part of bar I and heating perithallium；Described ignite bar II connection heating perithallium and heating plate.
Described heating perithallium is the symmetrical semicylinder of two panels, and the bar I that ignites, the bar II that ignites are along the axially connection two of battery bundle
Piece heats perithallium.
The thick asbestos of 0.3mm are enclosed in winding 1 between described battery bundle lateral wall and heating perithallium；Described glass fibre encloses
The thick asbestos of 0.3mm are enclosed in winding 2~3 between layer and heating perithallium；Described glass fibre perithallium encloses 0.23mm for winding 2~3
Thick glass fibre.
The beneficial effects of the invention are as follows：
(1) heating perithallium burns simultaneously with center heating plate, and electrolyte is rapidly achieved molten condition in can making thermal cell.
For activationary time requirement less than 0.5s, the fitted outside thermal cell of element cell design thickness 1.3mm~1.5mm, by the structure
Design, the low-temp activation time of thermal cell can shorten 0.15s (thermal cell low-temperature working scope is -20 DEG C~-45 DEG C).
As a result of technical scheme, after heating perithallium burning, thermal cell can be quickly made under low-temperature condition
The temperature of side asbestos perithallium, glass fibre perithallium, shell and battery cover is raised, without from the heat absorption of center heating plate, central hot
5%~10% can be reduced during amount design.Meanwhile, thermal cell fixed cover is aluminium, copper and other heat absorptions larger material or building ring
When border is low temperature low gas, 50% or so can be lengthened working hours.
(2) after the burning of heating perithallium, the heat of generation can produce heat radiation to battery bundle；It is larger for volumetric specific power
Pulsed discharge thermal cell, by this structure design, heating perithallium thermal design is the 10% of thermal cell total amount of heat, and center heat sets
It is calculated as the 90% of thermal cell total amount of heat.
Brief description of the drawings
Fig. 1 is thermal cell structural representation of the present invention；
Fig. 2 is insulation construction schematic diagram in side of the present invention；
Fig. 3 is that side insulation construction of the present invention ignites structural representation.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples, and the present invention includes but are not limited to following implementations
Example.
The invention provides a kind of thermal cell activation initial stage, to shell body, the side insulation construction of battery bundle heating simultaneously.
The present invention is by glass fibre perithallium 504, interior asbestos perithallium 501, heating perithallium 502, outer asbestos layer 503, big heating
Piece 506 and the bar I 3 that ignites ignite bar II 505 composition.Heating perithallium 502 is located between interior asbestos perithallium 501 and outer asbestos layer 503,
Insulation construction assemble sequence in side is that interior asbestos perithallium 501- heating perithallium 502- ignites the outer asbestos perithallium 503- glass of the 505- of bar II
Glass fiber perithallium 504.
Reference picture 1, battery case 5 group of the thermal cell by battery cover 1, ignition part 2, the bar I 3, battery that ignites bundle 4 and with insulation
Into side insulation is located in band temperature keeping battery shell 5.Side insulation assembling process is as follows：
Reference picture 2, is put into big non-porous asbestos 507 in battery case, places into big heating plate 506.Assembling is taken out to attach,
Assembling attaches winding 1 and encloses the thick asbestos 501 of 0.3mm, be then around 2 into heating perithallium 502, will then ignite bar II
505 attach axial direction across assembling docks with heating perithallium 502, then winds the thick asbestos 503 of 2~3 circle 0.3mm, and finally winding 2~
3 circle 0.23mm thick glass fibre perithallium 504, attaches together with assembling and is put into battery case, takes out assembling and attaches.
Reference picture 1 and Fig. 3, ignition part 2 is under fire in thermal cell, and ignition part lights the bar I 3 that ignites, and the bar I that ignites ignites from two ends
Heating perithallium 502 and the activated ignition element tied up of battery, heating perithallium 502 burn light the bar II 505 and greatly of igniting from top to bottom
Backing 506.
