The invention relates to the technical field of lithium battery modules, in particular to a vehicle cylindrical lithium battery module based on heat pipe and liquid cooling coupling heat dissipation,and the battery module comprises a lithium battery pack, heat dissipation aluminum plates, a heat dissipation aluminum pipe, battery lower bearing plates and battery upper cover plates. Every two rowsof batteries are fixed through two aluminum plates, the aluminum plates are separated from the batteries through insulated heat conduction silica gel pads, and battery installation insertion holes are formed in the lower bearing plates and the upper cover plates of the batteries to fix the batteries. The upper ends of heat pipes are equidistantly attached to the heat dissipation aluminum plates,and the lower ends of the heat pipes penetrate through limiting holes of the lower bearing plates to contact with the heat dissipation aluminum plates; and the whole battery pack module is subjected to glue pouring treatment, and an organic silicon foaming material is adopted, so that the shock absorption performance and the flame retardance are very high. According to the battery module, the stability of the whole batteries can be maintained, the influence on other batteries caused by accidents due to faults of the single batteries can be effectively prevented, and in addition, the battery module can be well subjected to heat management by adopting an air conditioner circulating cooling type liquid cooling system and a heating system.
