Abstract

The invention discloses an air-cooling heat dissipation device of a power battery pack and a control method thereof. The device comprises a case body for placing a battery, a splitter piece and four air flow channels, wherein the four air flow channels comprise a first air flow channel, a second air flow channel, a third air flow channel and a fourth air flow channel. Four valves are respectivelyarranged between the case body and the four air flow channels, and the passages between the case body and the four air flow channels can be opened or closed by opening or closing the four valves. An air outlet flow path may be selected by controlling the first air flow channel and the second air flow channel to be opened or closed. At the same time, a control valve is arranged at the air duct connected with the fan, the switch position of the control valve is arranged at the left and right sides of the air duct, and the air inlet flow channel can be selected as the third air flow channel or the fourth air flow channel by operating the switch position of the control valve.

Description

technical field [0001] The present application relates to the technical field of heat dissipation, and in particular to an air-cooled heat dissipation device and a control method for a power battery pack. Background technique [0002] The energy crisis and environmental issues have brought tremendous pressure to the traditional automobile industry. In recent years, countries have issued plans to ban the sale of traditional energy vehicles. The government has continued to increase efforts to encourage and support the development of new energy vehicles. The era of new energy vehicles has arrived. Battery technology is one of the key technologies of new energy vehicles, and its performance directly affects the development of new energy vehicles. At present, the power battery pack used in new energy vehicles generates a lot of heat due to a series of chemical reactions inside the power battery pack during the rapid charging and discharging process, which will cause the temperatu...
