Description
Technical field
The utility model is related to cell art, and in particular to a kind of battery system interstitital texture.
Background technology
With the economic development with science and technology, energy crisis and environmental problem become increasingly conspicuous.In order to solve the two problems,
The whole world is greatly developed under the overall situation of new energy, and energy storage battery system and electrokinetic cell system are given birth to therewith, energy storage battery system
It is mainly used in energy storage station, electrokinetic cell is mainly used on electric automobile.
The B of Chinese patent literature CN 104393200, disclose a kind of battery case, including casing and are sealed in the case
Internal battery, the casing is set to bilayer, including the inner and outer wall being made up of fibrous composite, the inwall and outer
Grasping part is formed between wall, reflecting layer and thermal insulation layer are formed with the grasping part, wherein the reflecting layer is near described
Outer wall is set, and the inwall is formed with heating layer on the surface of the grasping part.And it does not consider battery mould
Heat exchange between block, the temperature inside balancing battery.
Temperature distributing disproportionation is even in battery system, and the heat exchange with external environment condition there is also difference, and this is resulted in system
Battery core uniformity be deteriorated, so as to reduce the performance and used life of battery system.Inside and outside circumstance of temperature difference can also cause battery
Water vapour condensation in system, causes system insulation failure, it may occur that the situation of dew condensation phenomenon has：
(1) battery works in psychro-environment, can be generated heat when battery operated while can be empty to air heating in battery system, heat
Gas runs into cold battery tank wall can condensation.
(2) battery is when heated, while air is also heated, hot-air runs into cold battery tank wall can condensation.
(3) air conditioning warm air is passed through in battery system, and running into cold object can condensation.
(4) battery operated heating, while to air heating in system, hot-air runs into cold water pipe or cold battery and battery
Tank wall can condensation.
(5) because humidity is larger in itself in battery system, when system temperature drops to dew point, there is condensation.
At present by natural heat dissipation, air-cooled, the cold mode of liquid avoids the uniformity of battery performance from being deteriorated, but these modes are present
Certain defect：
1) natural heat dissipation cannot meet battery system and be worked under high temperature, psychro-environment.
2) it is air-cooled to reduce battery system bulk temperature, but effect efficiency is low, and because inside battery construction can be formed
Many vortex, it is impossible to the temperature consistency effectively in control battery system, or even cause the temperature difference to aggravate.
3) liquid cold energy effectively reduces battery system bulk temperature and the temperature difference very much, if soaking battery module using conductive fluid,
Condensation in battery system can be solved causes insulation fault.But the weight of battery system can be so greatly increased, battery system is reduced
The energy density of system, while very high to the requirement of the degree of protection of battery system, and unsuitable later maintenance, increased design cost and
After cost.
At present, it is not specifically used to avoid the design of battery system internal condensation also.
The content of the invention
The utility model provides a kind of battery system interstitital texture, to reach in balancing battery system thermal field and prevent electricity
The purpose of condensation in cell system.
A kind of battery system interstitital texture, including battery system casing, it is characterised in that：In battery system casing
Wall, heat-conducting layer is set close to battery system cabinet wall, and heat conduction layer material wraps up battery module.
Further, described casing outside, thermal insulation layer is set close to battery system cabinet exterior, or in cabinet wall
Thermal insulation layer is provided between heat-conducting layer；The low thermal conductivity of insulating layer material is in the thermal conductivity of heat conduction layer material.
Further, described insulating layer material is polyethylene foamed, expanded polypropylene, polyurethane foams, titanium dioxide
Silica aerogel, mica, phenol formaldehyde foam, polystyrene foam.
Further, described heat conduction layer material is foamed silastic, foamed silica gel, the methyl phenyl vinyl that foams is organic
Silicon, organic silicon potting material.
Further, the fixed form of described thermal insulation layer and heat-conducting layer on battery system casing is gluing, extruding, spiral shell
Bolt is fastened.
Battery system interstitital texture of the present utility model has the beneficial effect that：
By setting heat-conducting layer, and battery module is wrapped up, the temperature difference in balancing battery system makes each of battery system
Battery module temperature keeps identical, the temperature consistency in battery system is improved, so as to improve battery performance and life-span；Battery system
The internal filling of system, the air in battery system is excluded as far as possible, reduces the water vapour content in battery system, it is to avoid system
Insulation fault occurs.
