Description

Battery water cooling plate and battery cooling device Technical Field The utility model relates to the field of battery cooling, in particular to a battery water cooling plate and a battery cooling device. Background The power of battery car is provided by the battery, the battery can produce the heat at charge and discharge in-process, if can not in time distribute away battery module's heat in time, can all produce very big influence to battery's duration and life-span, at present generally adopt the water-cooling board to dispel the heat to battery module, common water-cooling board includes base plate and runner, the runner can form through the grooved mode on the base plate, also can form through setting up the water pipe, the tip welding at the water pipe has the joint, use joint and water pump etc. to be connected, but adopt welded mode to have some drawbacks, for example, the joint can influence the structure and the material characteristic of joint because of the thermal effect when welding, the welding bead is protruding after the welding is accomplished, influence outside aesthetic measure, and all need the staff to weld moreover, more difficult location, processing strength and inefficiency. Accordingly, there is a need for a battery water cooling plate and a battery cooling device that help to eliminate the processing steps and improve the structural strength to overcome the above-mentioned drawbacks. Disclosure of utility model The utility model aims to provide a battery water cooling plate which is beneficial to omitting processing steps and improving structural strength. It is another object of the present utility model to provide a battery cooling apparatus including a battery water cooling plate that helps to eliminate processing steps and to improve structural strength. In order to achieve the above purpose, the battery water cooling plate provided by the utility model comprises a base plate and a water pipe arranged on the first side surface of the base plate, at least one part of the water pipe is bent, the water pipe is provided with a joint end extending out of one side surface of the base plate, the joint end forms a cylindrical joint structure in an extrusion molding mode, flow channels for flowing refrigerant are arranged in the water pipe and the joint structure, and an installation groove for installing a sealing ring is formed in the outer side wall of the joint structure. Preferably, the water pipe is a flat tubular member, and the base plate is a square plate which is arranged in a straight manner. Preferably, the joint structure is disposed orthogonally to the first side surface of the substrate. Preferably, the water pipe is arranged in a multi-section winding manner on the first side surface of the base plate. Preferably, the battery water cooling plate further comprises a plurality of support pipes, wherein the support pipes are arranged beside the water pipes and/or are inserted between the water pipes. Preferably, the support tube is a flat tubular member, and the support tube is flush with the bottom surface of the water pipe. Preferably, the substrate comprises a second side surface opposite to the first side surface, the joint structure upwards passes through the second side surface, and the second side surface is provided with a layer of insulating glue in a hot melting pressing manner.
