Description
Technical field
The invention belongs to new energy vehicle power battery technology fields, and in particular to a kind of new energy car battery coldplate.
Background technique
New-energy automobile refers to using vehicle power supply as power, with motor driven wheels travel, meets road traffic, safety law
Advise the vehicle of requirements.Since the influence to environment is smaller with respect to orthodox car, as the requirement of energy-saving and emission-reduction is gradually stringent,
The development prospect of new-energy automobile is had an optimistic view of extensively.
The electric power of new energy vehicle is stored by vehicle-mounted power battery and is provided, and power battery requires have stability, safety
And reliability.The heat that power battery not only discharges in energy sources conversion will have a direct impact on the stability of battery, Er Qiehuan
The too low conversion that also will affect battery electric power of border temperature, causes course continuation mileage too low.Therefore, temperature of powered cell is controlled aobvious
It obtains most important.
Air-cooled and water-cooling mode is generallyd use currently, cooling for new energy vehicle power battery, is dissipated using air-cooled
The mode of heat is although low in cost, but influenced by ambient temperature big, and heat dissipation effect is undesirable under the high temperature conditions, and traditional
The mode of water-cooling generallys use battery cooling plate, but since battery cooling plate inner space is narrow, leads to coolant liquid not
It can be equably full of battery cooling plate, keep battery cooling plate each section temperature difference larger, it is bad to the cooling effect of power battery.Cause
This, a kind of inside of having come into being is disposed with the battery cooling plate (referring to Chinese patent CN207021362U) of water conservancy diversion rib,
To increase the area coverage of coolant liquid, the effect of heat exchange is improved.But this battery cooling plate not only arranged by water conservancy diversion rib
In simple, hydrokinetic influence is not considered, causes the flow and flow rate difference of each runner very big, battery cooling plate each section
The temperature difference it is still very big, and coolant liquid makes slowly to flow from one side of battery cooling plate in the internal flow of battery cooling plate
To other one side, especially only closer from liquid outlet, the heat transfer effect of coolant liquid is poorer, and it is each to also result in battery cooling plate
The partial temperature difference is big.
The heating of new energy vehicle power battery generallys use the mode of electric heating or hot-water heating heating, currently, either electric heating
Or hot-water heating heating, requires an individually designed jacket heating system, and leading to the heat management system of power battery, not only component is various,
And control logic is complicated, and reliability is bad.
Solving problem above becomes the task of top priority.
Summary of the invention
It is big to solve existing battery cooling plate each section temperature difference, it is bad to the cooling effect of power battery, while cannot be simultaneous
The technical issues of holding as cell heater, the present invention provides a kind of new energy car battery coldplate.
To achieve the above object, technical solution of the present invention is as follows:
A kind of new energy car battery coldplate, including shell are provided with inlet in the side outer rim of the shell and go out
