Description
Technical field
The utility model belongs to battery technology field, and in particular to a kind of simple battery thermal control system using phase-change material
System.
Background technique
Battery must generally work within the scope of certain temperature, and electrical property can be only achieved optimal, and safety is protected
Card.Especially large-sized battery pack, if thermal runaway occurs for certain single battery or battery module, it will and lead to pernicious chain reaction
Generation, catching fire, in addition explosion.
In terms of battery thermal control, traditional approach mainly uses air-cooled or liquid cooling.Air cooling way, system structure is relatively simple,
It is light-weight, but due to Measurement of Gas Thermal Conductivity, low efficiency.Liquid cooling mode, heat exchange efficiency is high, however still has centainly not
Uniformity is limited by the structure of battery pack itself, and efficiency is not also high, and since system structure is complicated and potential risk, leads
Cause with limited.
When especially battery pack is in closed environment and is limited by volumetric constraint, phase-change material can preferably control battery
The temperature of group improves its performance, service life and safety.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of simple battery based on phase-change material
Heat control system, the utility model is simple and compact for structure, high reliablity, and the processing of phase-change material packet and introducing are convenient, without consuming volume
Outer power is able to satisfy the radiating requirements of power battery, has potential application prospect.
The technical scheme adopted by the utility model is
A kind of simple battery heat control system based on phase-change material, including battery housing, be placed in shell it is single or
Several battery modules of person, each battery module include several single batteries, between single battery, between single battery and shell
Gap be placed with phase-change material packet, the heat generated when can absorb battery charging and discharging, make battery work preferably working
In temperature.
The single battery is rectangular cell, is soft package lithium magnesium one-shot battery.
The phase-change material packet be vacuum seal be equipped with solid-liquid phase change material aluminum plastic film packet, shape be it is rectangular, surface is flat
Face or corrugated.
The phase-change material fusing point selection is in the working range that battery is suitable for.
The battery and phase-change material packet are in close contact, heat conduction.
Utility model works process:
Battery pack work when especially big multiplying power discharging when, inside generate heat by the phase-change material between single battery
Packet absorbs, and the heat in outside is exported by shell or absorbed by the phase-change material packet between battery and shell, keeps battery work
In suitable operating temperature and its uniformity of temperature.
Compared with prior art, the utility model has the beneficial effects that
The configuration of the present invention is simple, high reliablity；Phase-change material packet contacts closely with battery, and heat transfer efficiency is high, phase-change material
The a certain proportion of corrugated core in surface is wrapped, swelling stress brought by battery discharge can also be alleviated；The processing of phase-change material packet
Simply, it is added easy.The radiating requirements of power battery are able to satisfy, there is potential application prospect.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the simple battery heat control system based on phase-change material of the utility model.
Specific embodiment
With reference to the accompanying drawing and specific example the present invention will be further described.
Embodiment 1
As shown in Figure 1, a kind of simple battery heat control system based on phase-change material, including shell 1, it is placed in shell
Battery pack, battery pack are made of multiple single batteries 2, and phase-change material packet 3 is filled between single battery.Electricity is said with fiber gummed paper
Group packaging in pond is compact, is in close contact battery and phase-change material packet.
Phase-change material packet is the solid-liquid phase change material being added into laminated aluminum film in this example, and through Vacuum Package, heat is melted
Cold moudling.
Select phase-change material fusing point at 55 DEG C in this example, actual temp range can be selected specifically according to actual needs
It selects, is not limited by the specification of specific material, select space big.
