Problems solved by technology

[0003] When the current battery is managed for heat dissipation, it generally surrounds a water-cooled or air-cooled heat dissipation mechanism that is attached to the outer wall of the battery pack. However, the center of the battery pack heats up faster, and it is difficult for a single heat dissipation mechanism to quickly turn the battery pack from the inside to the outside. Heat cooling, thereby greatly reducing the service life of the battery pack, reducing the cooling performance and heat conduction effect of the heat dissipation mechanism, the power and density of the battery pack used in ordinary new energy vehicles are high, and the guided blowing and adsorption cooling of heat can reach Less than the ideal actual demand, often promotes the concentration of the battery's own heat, so that the exposed part of the battery cannot naturally exchange heat, which affects the practical application of the battery's power supply requirements.

Embodiment 1

[0032] Example 1, such as Figure 1-3 As shown, when the heat dissipation fan A4 and the heat dissipation fan B406 are started, the inner spiral air duct 401 and the air guide column 402 are used to cooperate with each other, so that the heat dissipation fan A4 forms a wind force and circulates in a spiral flow guide structure, and flows between the air guide column 402 and the air guide column 402. Blind hole A403 cooperates to discharge, through the connection of air guide pipe A404 and air guide pipe B407 and the placement of blind hole B405, the wind force emitted by cooling fan B406 flows out from blind hole B405, and the annular groove 2 can be diffused from inside to outside Guided airflow not only cooperates with cooling fins 5 to air-cool and dissipate the battery pack, but also transfers the dissipated heat to the inner wall of the annular groove 2, and cooperates with the water-cooling structure to effectively dissipate heat and enhance the practical application effe...

Embodiment 2

[0033] Example 2, such as figure 1 and Figure 6As shown, the installation cooperation of the rubber column 13 and the positioning of the mounting seat 1 have played an auxiliary fixing role. At the same time, under the installation cooperation of the rubber column 13 and the protective airbag 3, the vibration and impact of the device are alleviated, and the installation of the device is improved. Stability and shock resistance reduce damage to components.

[0034] Working principle: when the device is in use, the battery pack is divided into four groups under the separation of the cooling fins 5 and placed in the annular groove 2, and the cooling fan A4, the water pump 8 and the cooling fan B406 are respectively activated by the controller 10, and the heat dissipation When the fan A4 and the cooling fan B406 start, the cooling air is blown into the annular groove 2 and guided, so that the heat is extended to the inner wall of the annular groove 2 under the heat dissipation c...

Abstract

The invention discloses a heat dissipation mechanism for new energy automobile battery management. The heat dissipation mechanism comprises a mounting base and a controller; rubber columns are arranged at the four corners of the mounting base; annular grooves connected with one another are formed in the top of the mounting base; protective air bags matched with the rubber columns are arranged on the outer side of the mounting base; a cover plate is arranged at the tops of the annular grooves; heat dissipation through openings are formed in the four corners in the cover plate; and air cooling heat dissipation assemblies are arranged in the middle portions of the bottoms of the annular grooves. Through mutual cooperation of heat-conducting water-cooling assemblies, a battery pack is annularly wound around the clinging position of the battery pack and a heat-conducting silica gel sheet, so that the actual heat dissipation heat of the battery pack is absorbed and permeated at the first time; under the circulating water-cooling cooling of water in a circulating water tank, the functions of heat absorption relieving and heat dissipation cooling of the outer wall of the device are provided; and a cooling effect enabling heat of the device to be dissipated outside is provided.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a heat dissipation mechanism for battery management of new energy vehicles. Background technique [0002] Electric vehicles mainly use battery packs as power devices. The battery pack needs to be charged and stored by the outside world, and then provide power to the electric vehicle. The battery pack works by repeatedly charging and discharging; [0003] When the current battery is managed for heat dissipation, it generally surrounds a water-cooled or air-cooled heat dissipation mechanism that is attached to the outer wall of the battery pack. However, the center of the battery pack heats up faster, and it is difficult for a single heat dissipation mechanism to quickly turn the battery pack from the inside to the outside. Heat cooling, thereby greatly reducing the service life of the battery pack, reducing the cooling performance and heat conduction effect of the he...
