The invention discloses an equidistant T-shaped runner air cooling system for heat dissipation of a power battery pack. The equidistant T-shaped runner air cooling system comprises an inlet section, an inlet guide plate, cooling runners, an outlet guide plate, an outlet section and the power battery pack, wherein the outlet guide plate and the inlet guide plate are distributed at the upper and lower sides which are kept at certain spaces from the power battery pack in parallel; upper and lower air runners are formed by the spaces separately; the upper and lower air runners and the cooling runners formed by the spaces between various single batteries in the power battery pack are in a vertical relationship; the inlet section is connected with the inlet guide plate; the outlet section is connected with the outlet guide plate; the inlet section and the outlet section are in a vertical relationship; and air enters the inlet guide plate from the inlet section, reaches the lower air runner,enters the cooling runners vertical to the lower air runner under the oppression of the inlet guide plate, reaches the upper air runner through the cooling runners, is converged under the oppression of the outlet guide plate and then flows outside from the outlet section.
Description
technical field [0001] The invention relates to the field of power battery air cooling systems, in particular to an equidistant T-shaped channel air cooling system for heat dissipation of power battery packs. Background technique [0002] In recent years, the exhaust emissions of fuel vehicles have aggravated the problem of environmental pollution, and many large and medium-sized cities have experienced smog, which makes the country vigorously promote the development of electric vehicles or hybrid vehicles. As the core component of electric vehicles, battery packs provide energy for the driving of electric vehicles. Therefore, ensuring the normal operation of the battery pack can not only prolong the service life of the battery, but also promote the development of the power vehicle industry to a certain extent. The important factors affecting the service life of the entire power battery pack are the temperature of the battery pack and the internal temperature difference. T...
