New energy battery pack with water cooling unit module

Abstract

The invention discloses a new energy battery pack with a water cooling unit module. The battery pack comprises a battery pack shell, a protective shell, a water-cooled tube, a connecting pipe, a scavenging valve and a battery pack, the battery pack shell is mounted in the protective shell; a transverse shaft is horizontally and rotationally installed on the right side wall of the protective shell.A gear is mounted at the right end of the transverse shaft; the gear is meshed with tooth blocks; the tooth blocks are fixed to the lower end face of a pendulum bob plate at equal angles. The pendulum bob plate is of an arc-shaped structure; the pendulum bob plate is mounted at the bottom end of a fixed rod; the top end of the fixed rod is fixedly connected with the right end of a rotating shaft;the fixed rod, the pendulum bob plate and the gear are all located in a sealing shell. The sealing shell is fixed to the right side of the protective shell, the inertia acting force in the automobilerunning process is used for driving a heat dissipation structure in the battery pack to operate correspondingly, efficient heat dissipation can be conducted on the water cooling pipe and the batterypack in the battery pack without adding extra power equipment, the cost is greatly reduced, and the cooling effect is better.

Description

technical field [0001] The invention relates to the technical field of new energy battery packs, in particular to a new energy battery pack with a water cooling unit module. Background technique [0002] New energy battery packs are mostly used in new energy vehicles. Unlike vehicles driven by internal combustion engines / fuel-consuming engines, new energy vehicles are mostly driven by pure electricity. Compared with traditional engine vehicles, they are more energy-saving and environmentally friendly. New energy battery packs A battery pack is formed by combining several batteries, and then the battery packs are connected in series to form a battery pack. Due to the use of a large number of batteries, heating will inevitably occur during the continuous charging and discharging of the battery. Therefore, the existing technology will A water-cooling module is added to the battery pack, but the existing new energy battery pack with a water-cooling module has the following probl...

Problems solved by technology

[0003] The water-cooling module is mostly composed of a pipeline structure for passing coolant and a supply mechanism for coolant. The water-cooling tube for flowing coolant is wound on the outer surface of the battery pack casing, and the temperature of the internal coolant rises correspondingly after absorbing heat. Part of the heat is dissipated, and additional power equipment structures such as fans will be used, resulting in a further increase in energy consumption of the battery pack and a corresponding increase in cost
