It causes thermal resistance (Thermal Resistance) excessively high, has been easy that heating speed is slow and the uneven situation of temperature.
However, embodiment according to the present invention, then do not need to install electric blanket additional in battery module support frame upper and lower again
Or resistive heating elements, but directly the liquid in liquid heat exchanger 150 is heated, then by heat sink 140, i.e.,
It can reach the effect heated to battery 120, can reduce and cause the uneven phenomenon of heating temperature because thermal resistance is excessively high.
According to the heat management system of battery module disclosed in U.S. Patent Publication No. US2014/0193683, cooling water pipe
It is introduced directly among battery module, can be too long because of cooling line if 120 quantity of battery is excessive, cause internal coolant resistance
Coefficient is excessive, must be driven using high-lift pump, will cause cooling line hypertonia, has potential pipe joint or material bad
When, cooling tube booster situation is caused, causes battery module that the situation of short circuit occurs.
In contrast, a kind of embodiment according to the present invention, extends the element between battery 120 as heat dissipation path
The temperature-uniforming plate 443 of heat sink 140, and the liquid line in liquid heat exchanger 150 need not extend to battery 120 it
Between, it is only necessary to extend the heat exchanger plate 442 of heat sink 140.The liquid line of liquid heat exchanger 150 does not need too high
Pressure, therefore do not need to drive using high-lift pump, loine pressure can be reduced, avoid the generation of booster situation.

Electric transportation carrier has the risk to collide with each other, such as traffic accident.When having a car accident, the liquid of battery system 100
Pipeline in heat exchanger 150 may rupture, and make liquid leakage, and make multiple batteries 120 that short circuit occur and cause electricity
Cell system 100 explodes.Compared to the existing technology of the embodiment of Fig. 1 and aforesaid U.S. Patent, in the embodiment of Fig. 2
In, liquid heat exchanger 150 and its liquid line are respectively positioned on outside shell 110, therefore can reduce liquid heat exchanger 150
Leakage contacted with multiple batteries 120, can be avoided multiple batteries 120 and short circuit occur, and reduce battery system 100 explosion
Generation.
In addition, (not indicated in one embodiment with attached drawing), the heat of liquid heat exchanger 150 and heat sink 140 is handed over
Change plate 442, be all set in outside shell 110, and liquid heat exchanger 150 is contacted with the one side of heat sink 140, do not need across
Shell 110, so as to increasing the heat exchanger effectiveness between liquid heat exchanger 150 and heat sink 140.Preferably, shell 110
It is contacted with the another side of heat sink 140, and makes heat that can also radiate by shell 110.
Fig. 1 and Fig. 2 is please referred to again.Preferably, heat sink 140 includes an at least airtight cavity 441, and close
Being equipped in closed chamber body 441 can be in the alternate working fluid for carrying out phase change of liquid vapour two, and content is few so that air pressure pole in cavity
It is low.The motion mechanism of airtight cavity 441 is as described below.The working fluid of liquid phase passes through the capillary channel in airtight cavity 441
It is flow to temperature end, flashes to vapour phase after absorbing heat.It generates partial high pressure in the cavity at this time, drives the working fluid of vapour phase high
The working fluid of flow speed and direction low-temperature end, vapour phase is back to temperature end after low-temperature end condenses into liquid phase, then through capillary force, with this
The mode circulation action of sample.Preferably, the working fluid in airtight cavity 441 is in the state of liquid vapour two-phase coexistent,
Two-phase forms the hot superconducting phenomenon that Isothermal Hot passes without the temperature difference.In one embodiment, airtight cavity 441 is set to heat sink
In 140 temperature-uniforming plate 443.Preferably, airtight cavity 441 is all set in temperature-uniforming plate 443 and heat exchanger plate 442.In
In a kind of embodiment, temperature-uniforming plate 443 can be a cuboid, so that 441 straight line of airtight cavity for being set to temperature-uniforming plate 443 prolongs
It stretches and is not bent, so as to increasing heat transfer efficiency.
Working fluid in airtight cavity 441 is preferably non conducting fluid, such as can be freon, ammonia, acetone etc..
After can further avoiding the rupture of airtight cavity 441 in this way, least a portion of working fluid leaks out and causes percentage of batteries core 120
