Vehicle-mounted battery thermal management device

Abstract

The invention discloses a vehicle-mounted battery thermal management device. The vehicle-mounted battery thermal management device comprises a water passing main pipe, a water cooling assembly located on at least one side edge of the water passing main pipe, and a water circulating pipeline which is connected with the water passing main pipe; the water passing main pipe comprises a water feeding main pipe and a water returning main pipe which are arranged in parallel; the water circulating pipeline comprises a water feeding header pipe and a water returning header pipe; the water cooling assembly comprises a plurality of water cooling vertical plates which are vertical to the water passing main pipe and are distributed at intervals, water cooling bottom plates which are located between the adjacent water cooling vertical plates and are parallel to the water passing main pipe, a vertical plate water passing branch pipe which is connected between the water passing main pipe and each water cooling vertical plate and a bottom plate water passing branch pipe which is connected between the water passing main pipe and each water cooling bottom plate; each vertical plate water passing branch pipe comprises a vertical plate water feeding pipe and a vertical plate water returning pipe; each bottom plate water passing branch pipe comprises a bottom plate water feeding pipe and a bottom plate water returning pipe. By adopting the vehicle-mounted battery thermal management device disclosed by the invention, the problem that the heat radiation effect of an existing battery module is not good is solved, and uniform cooling and efficient cooling are realized; the device is compact in structure, is safe and reliable and has high practicability.

Description

technical field [0001] The invention relates to a thermal management device, in particular to a vehicle-mounted battery thermal management device, which belongs to the technical field of water cooling equipment. Background technique [0002] New energy electric vehicles refer to vehicles powered by on-board power supplies and driven by motors. As the core component of a pure electric vehicle, the performance of a power battery will directly affect the performance of a pure electric vehicle. In order to meet the mileage requirements of electric vehicles and achieve a predetermined voltage and capacity, multiple lithium-ion batteries need to be connected in series and parallel to form a power battery module; a certain number of modules are connected in series to form a circuit. Since the module installation space reserved in pure electric vehicles is mostly small and irregular in shape, the battery core heats up during battery operation, and the temperature rise and imbalance...
