Operation principle
When the mode that the present invention is combined using the flat hot pipe 3 with high-termal conductivity and cooled plate 2 is to battery set charge/discharge
Temperature is effectively controlled, and on the one hand will dissipate substantial amounts of heat when lithium battery 4 is in larger current discharge and recharge, battery core temperature
Rise, now by being that lithium battery 4 is spaced heat conductive pad 5, heat conduction soldering 6 and flat heat with the flat hot pipe 3 of battery core mediate contact
Pipe 3 is contacted, and heat is passed to the cooled plate 2 of the lower end of flat hot pipe 3 from lithium battery 4, and heat is stored in the water of cooled plate 2,
The temperature of water can slowly rise, while the temperature of battery core rises and will be suppressed, the temperature of the reclaimed water of cooled plate 2 as heat shifts
Will be with carrying out heat exchange outside battery case when rising to a certain extent, it is ensured that water temperature is led to not over the temperature value of a setting
Cross such a process and realize the purpose to be radiated to the battery core of lithium battery 4；On the other hand, the low temperature less than 0 ° can be to lithium battery 4
Charge-discharge performance adversely affect, now need to heat to lithium battery 4, be stored in the water in cooled plate 2 in heat insulation effect
Being changed into the ice of solid-state in preferable battery case from liquid needs to release substantial amounts of heat, and this partial heat can pass through flat hot pipe
3 pass to the battery core of the lithium battery 4 of the other end, so that temperature decline is suppressed the temperature of lithium battery 4 at low temperatures,
During cooling water temperature slowly declines, when the temperature value set less than one, adding outside battery case can be passed through
Thermal heats to cooling water, so as to realize that heat carries out heating thermal conductive silicon by the way that water and heat pipe are lasting to lithium battery 4
The effect of heat conductive pad 5 of glue material matter is to fill the gap between lithium battery 4 and flat hot pipe 3, while is also to have flame-resistant insulation
The material of energy, its thermal conductivity factor are more than 1.0W/m.k, and lithium battery 4 passes through heat conductive pad 5 and flat hot pipe 3 carries out heat exchange, surrounds
The netted flame-resistant insulation piece of lithium battery 4 does not influence heat exchange performance between the two, 3 surface coated flame-resistant insulation of flat hot pipe
The thermal conductivity factor of layer is more than 2W/M.K, heat pipe has an efficient heat-transfer capability, and the short side part of L-type flat hot pipe 3 is with being connected
Heat transfer sheet 7 carries out heat exchange, and heat transfer sheet 7 is made of aluminium alloy, and heat transfer sheet 7 carries out heat exchange with cooled plate 2 again, finally by
Recirculated water and the outside purpose for carrying out heat exchange, realizing control lithium battery electric core temperature.
