Condense.Condensed worker quality liquid is back to evaporator section by the effect such as gravity or capillary force, continues to receive thermal evaporation, so past
It is multiple.Because adopting heat pipes for heat transfer is along with the phase transformation of its internal working medium, therefore the ability of heat pipe transmission heat is very high.Simultaneously because phase transformation
During Temperature of Working keep constant, therefore the temperature difference at heat pipe two ends also very little.The heat management system design of the disclosure is exactly
Take full advantage of above-mentioned adopting heat pipes for heat transfer characteristic.
It must be noted that in the present embodiment, under different working conditions, heat pipe had both been participated in lithium battery surface and electricity
The heating process of heat is provided in the case of pond, is also assisted in heat transfer in lithium battery surface and battery case to extraneous radiating
Journey.Therefore, heat pipe initial and end two ends will serve as evaporator section or condensation segment under different operating modes.If heat pipe only relies on gravity makes liquid
Body is back to evaporator section from condensation segment, and its evaporator section must be placed at down, and condensation segment is upper.After will so fixed placement being caused
Heat pipe cannot simultaneously meet the dual-use function that heat management system described in the disclosure is heated or radiated to electric automobile lithium battery
It is required that.Therefore, in the disclosure, inside heat pipe will have capillary-porous structure, and its internal working medium will be flowed back by capillary force,
Under, condensation segment is not limited heat pipe evaporator section in upper placement, will simultaneously meet adding for heat management system designed by the disclosure
Heat, heat sinking function.In addition, the heat pipe with capillary-porous structure can also more preferably meet electric automobile space requirement.Such as, at certain
In kind electric automobile, it is desirable to which liquid tank can only be arranged in lithium battery box top.Under this condition, heat pipe will be placed using inverted L shape.
Due to possessing capillary-porous structure, even if the heat pipe that inverted L shape is placed can also implement heating, heat sinking function, related heat management is met
It is required that.As can be seen here, the heat pipe in the disclosure can according to real space requirement carry out all around, positive L-type or inverted L shape put
Put.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to above-described embodiment
The present invention has been described in detail, it will be understood by those within the art that；It still can be to above-mentioned each implementation
Technical scheme described in example is modified, or carries out equivalent substitute to which part technical characteristic；And these modification or
Replace, do not make the scope described in the essence disengaging various embodiments of the present invention technology of appropriate technical solution.
