Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of structural representation with the battery pack of liquid-cooling heat radiator of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of battery pack with liquid-cooling heat radiator of the utility model embodiment comprises:
Battery case body 10, circulating pump 20, radiator 30, detector 50, separator 60, filter 70, circulation pipe 40, battery case body 10, circulating pump 20, radiator 30 seal circulation with detector 50 by circulation pipe 40 and are communicated with, circulation pipe 40 is communicated with separator 60, filter 70 successively by a three-way pipe, the ft connection of filter 70 and circulation pipe 40, between circulation pipe 40 and each assembly, circular flow is connected with circulation fluid.Specifically, in battery case body 10, be provided with battery module, detection module, after battery case body 10 seal group installs into, battery case body 10 inside vacuumized, the inner nitrogen injection of battery case body 10.The flowing that circulating pump 20 is circulation fluid provides power, when in battery case body 10, temperature is too high, circulation fluid flows through radiator 30 in circulation pipe 40, radiator 30 makes circulation fluid reduce temperature, circulation fluid flows in battery case body 10, take away in battery case body 10 and the heat of battery, battery is lowered the temperature, otherwise, when in battery case body 10, temperature is too low, 30, radiator improves the temperature of circulation fluid, and battery case body 10 is heated up, with this repetitive cycling, ensure (in the 5 DEG C) fluctuation in a less temperature range of battery in battery case body 10.The temperature making the battery module in battery case body 10 keep stable, improves the security performance of battery pack
Battery case body 10 is provided with relief valve (not shown), relief valve is unidirectional valve, when battery case body 10 internal pressure is excessive, and can by pressure inner excessive for battery case body 10 to discharging, because relief valve is unidirectional, can prevent extraneous air from entering box house.The degree of protection of casing is IP67.
Circulating pump 20 provides the power of circulation for circulation fluid, and circulating pump 20 is responsible for control by battery management system, when battery pack system internal temperature in allowed limits, circulating pump 20 does not work, and circulation fluid remains static in the entire system; When battery pack system internal temperature has exceeded 1 boundary's point, battery management system controlled circulation pump 20 works.
Radiator 30 is responsible for the effect that circulation fluid provides heating or cooling, and when battery pack temperature is too low, radiator 30 provides heat effect for circulation fluid; When battery pack system temperature is too high, radiator 30 provides thermolysis for circulation fluid.
Detector 50 comprises gas sensing transducer, temperature sensor and pressure sensor, wherein gas sensing transducer can be one or several in the transducers such as fluoride transducer, chloride transducer, hydrocarbonylation thing transducer, carbon dioxide sensor, hydride transducer, self-induction type pressure sensor, temperature sensor, for induced cell discharge in chemical reaction a large amount of hydride, chloride, fluoride, hydrocarbons.
Whether the temperature sensor in detector 50 temperature of the circulation fluid of perception after radiator 30 can meet the requirement of battery pack system; The pressure of pressure sensor energy perception whole battery case body 10 inside, if pressure raises suddenly or reduces, pressure data can be fed back to battery management system by detector 50.
Separator 60 can be separated to be separated the impurity in circulation fluid, gas from circulation fluid, the circulation fluid being separated impurity and gas is sent back to again in battery case body 10 cyclic process, ensure the reliability in wherein circulation fluid and battery case body 10 and fail safe, it is worth mentioning that, the separate mode of separator 60 comprises physical separation and Chemical Decomposition two kinds.
After gas is separated by separator 60 from circulation fluid, isolated gas is through filter 70, dangerous substance, poisonous and harmful substance, combustible material etc. are stored in filter 70 by filter 70, innocuous gas (conventional gas) is disposed in air, avoid the poisonous and harmful substance in gas to be directly disposed in air, so that human body and environment are impacted.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
