Dynamic lithium battery is typically to be contained in multiple single lithium battery serial or parallel connection in different forms
A cell apparatus, the voltage needed for providing or capacity are provided together.Owing to lithium battery is in discharge and recharge
During himself temperature can raise, and when charge-discharge magnification is the highest heat up the fastest, especially to multiple
Cell composition device, the gathering of temperature faster, this by have a strong impact on battery service behaviour and
In the life-span, also result in battery generation vigorous combustion time serious and even explode.Therefore, temperature is to electricity
The performance impact of pool device is very big, and temperature is too high, too low and the unbalanced performance that all can affect battery.
At present, power lithium battery pool device mainly use Natural Heat Convection, Forced Air Convection heat transfer,
Vaporizer provides the modes such as low-temperature receiver heat radiation to carry out cooling, i.e. forces air at single battery shell stream
Move and its heat is taken away, due to shortcomings such as the heat conductivity of air are low, thermal capacitance is little, cause heat transfer coefficient
Little, cooling efficiency is low, and flowing that air is in cell apparatus uneven will affect battery dress
The temperature consistency put.
Wherein liquid-cooling heat radiation mode is owing to the specific heat capacity of liquid is much larger than the specific heat capacity of air, less stream
Amount just can take away bigger heat, thus takes the heat of battery system to its exterior efficiently,
Reduce the temperature rise of battery system, improve the serviceability of battery.The most a lot of battery systems all use
Liquid-cooling heat radiation mode is as dispelling the heat.But the existing cold and hot Managed Solution of liquid is mainly by liquid cooling plate block
It is clipped between two battery modules, or the interspersed cold pipeline of liquid between battery so that the heat that battery sends
The cold liquid of liquid can not be directly passed to, or owing to the very fraction outer surface of the cold pipe of liquid with battery connects
Touch so that bigger in the thermal resistance of the cold liquid of thermal source i.e. battery to liquid, so that temperature rise increases, no
The function of liquid cooling system can be played completely.
Utility model content
For the shortcoming and defect of prior art, this utility model provides a kind of electrokinetic cell heat radiation knot
Structure, to solve the problem that in existing electrokinetic cell heat dissipation technology, the thermal resistance of the cold liquid of liquid is excessive so that electricity
The heat produced during the work of pond can rapidly and efficiently be delivered to the cold liquid of liquid, and is taken to by heat rapidly
In its exterior environment.
In order to reach the effect above, technical solution of the present utility model is as follows:
A kind of electrokinetic cell radiator structure, including heat dissipation metal container and electrokinetic cell, it is characterised in that
Being provided with sweat cooling iknsulating liquid in described heat dissipation metal container, described electrokinetic cell is arranged on metal
On the diapire of heat-dissipating container and be at least partially submerged in described sweat cooling iknsulating liquid.
Preferably, the top of described heat dissipation metal container or be provided with height and press on the sidewall at top
Air valve.
Preferably, the liquid level of described sweat cooling iknsulating liquid is less than described heat dissipation metal container
Highly.
Preferably, the outer surface of described heat dissipation metal container is provided with power output end.
Preferably, the outside wall surface of the top cover of the most described heat dissipation metal container is provided with radiating fin.
Preferably, described electrokinetic cell includes multiple cell.
Further, the plurality of cell serial or parallel connection.
Further, the plurality of cell stacking arranges or be arranged in parallel.
Advantage of the present utility model with have the beneficial effect that electrokinetic cell radiator structure of the present utility model,
By electrokinetic cell being set directly in the sweat cooling iknsulating liquid within heat dissipation metal container, dynamic
The heat produced when power is battery operated can rapidly and efficiently be delivered to sweat cooling iknsulating liquid, and fast
Heat is taken in its exterior environment by speed, significantly reduces the temperature rise of battery system, improves electricity
The serviceability in pond, extends the life-span of battery.
