Description
Technical field
The present invention relates to a kind of battery radiator structures, more particularly, to a kind of battery modules unit knot of adjustable thermal resistance
Structure.
Background technique
In recent years, since electric car can be good at reducing the application of fossil fuel, country widelys popularize new energy vapour
Vehicle, lithium battery industry are developed rapidly.Core component power battery pack as electric vehicle is to restrict Development of Electric Vehicles
Key factor.Mould group can not only effectively improve battery pack energy density, and can carry out any string and number, thus the emphasis of exhibition.
It is well known that the device that mould group is made of multiple battery cells can generate a large amount of heat in charge and discharge process, can draw
It plays battery core temperature to increase, the excessively high influence battery life of battery core temperature and performance, it is also possible to cause thermal runaway, cause safe thing
Therefore.Battery core temperature distributing disproportionation weighing apparatus can accelerate the inconsistency for leading to single battery core, influence the service life of battery core.Therefore optimize
The radiator structure of mould group is important link.
Nowadays mould group heat dissipation is there are mainly two types of mode: first, by the aluminium sheet between battery core by heat derives to mould group side
Face or bottom surface carry out natural heat dissipation.There are two types of situations among these: aluminium sheet is relatively thin, and heating conduction is poor, and heat dissipation effect is poor；Aluminium sheet compared with
Thickness, quality is larger, drags down power battery energy density.Second, by water-cooling pattern, although heat dissipation effect is preferable, cost
Higher, structure is complicated, and water cooling tracheal rupture is easy to cause leakage to send a telegraph core short circuit, and water-cooling system increases battery system quality,
Reduce energy density.Secondly, soft pack cell has slight bulging in charge and discharge process, there is vibration during battery core vehicle movement
It is dynamic, buffer gap is needed, mechanical damage is otherwise be easy to cause.
Summary of the invention
The present invention is intended to provide one kind can be adjusted by thermal resistance, the requirement according to operating condition to thermal resistance is different, can be right
When the resistance value of thermal resistance is more demanding, the energy density of mould group is improved by reducing the dosage of heat-conducting glue and reduces mould group cost
The battery modules cellular construction of adjustable thermal resistance, including battery core, plastic stent and heat dissipation aluminium block, battery core are arranged in plastic stent
On, heat dissipation aluminium block is arranged on plastic stent, and heat dissipation aluminium block includes outer heat sink, contact plate, partition plate and mounting plate, contact plate
Heat for receiving to pass over from battery core, partition plate are separated out radiating control locellus between contact plate and outer heat sink,
Mounting plate is connect for the aluminium block that will radiate with plastic stent, the perforation of radiating control locellus both ends.Radiating control locellus has reserved sky
Between for smearing heat-conducting glue, to indirectly increase the heat-conducting area between contact plate and outer heat sink.Realize by adjusting
The dosage of heat-conducting glue come improve mould group energy density and reduce mould group cost.
Preferably, being additionally provided with heat-conducting glue between contact plate and battery core.Heat-conducting glue is filled between contact plate and battery core
Keep the contact between contact plate and battery core even closer, improves basic radiating efficiency.
Preferably, heat dissipation aluminium block includes the second partition plate, third partition plate, partition plate, the second partition plate, outer heat sink
The second radiating control locellus is surrounded with contact plate, the second partition plate, third partition plate, outer heat sink and contact plate surround third and dissipate
Thermal control locellus.Heat dissipation grade can be divided into three-level by three radiating control locellus, when needing to adjust radiating efficiency, it is only necessary to root
Heat-conducting glue is filled in corresponding radiating control locellus according to required heat dissipation grade without controlling in single heat dissipation locellus
The amount of heat-conducting glue processed, to play the function of reducing complex procedures degree.
Preferably, partition plate, the second partition plate and third partition plate are parallel to each other.Three partition plates should be same work
Part can also be separated out radiating control locellus similar in three volumes while reducing manufacturing cost.
Preferably, there are two heat dissipation aluminium blocks or more than two, heat dissipation aluminium block is arranged on plastic stent close to battery core two
The part of side.The heat dissipation aluminium block that battery core two sides are arranged in is thickness in order to reduce battery modules unit.
Preferably, battery core two sides are additionally provided with heat dissipation otic placode.Heat dissipation otic placode is for increasing between battery core and outer heat sink
Effective contact area.
In conclusion the present invention has the advantage that can requirement according to operating condition to thermal resistance it is different, can be to thermal resistance
Resistance value it is more demanding when, by reduce heat-conducting glue dosage come improve mould group energy density and reduce mould group cost.
