Embodiment Construction
[0022] The present invention and its beneficial effects will be described in further detail below in conjunction with specific embodiments and accompanying drawings, but the specific embodiments of the present invention are not limited thereto.
[0023] like Figures 1 to 3 As shown, a battery pack cooling system for an electric vehicle includes a battery pack 1, the electric vehicle is provided with a battery pack installation area, and the electric vehicle is an electric vehicle with a side compartment for installing the battery pack. area, the side compartment includes an installation base plate 2 and a side wall 3 of the compartment, and the battery pack 1 is mounted on the installation base plate 2 in a ladder arrangement, so that the wall surface of the battery pack 1 is in contact with the installation base plate 2 and the side of the compartment. Between the walls 3 is formed an air duct 4 whose width gradually narrows from the front of the vehicle to the rear of the v...

The invention belongs to the technical field of cooling systems and particularly relates to a cooling system for an electric vehicle battery pack. The cooling system comprises the battery pack. An electric vehicle is provided with a battery pack installing region. The battery pack is installed on the battery pack installing region. An air way in the direction from the head of the vehicle to the tail of the vehicle is formed between the battery pack and the battery pack installing region. An air inlet and an air outlet are formed in the air way. The open direction of the air inlet is consistent with the direction of the head of the vehicle. Due to the fact that the air way is in the direction from the head of the vehicle to the tail of the vehicle and the air inlet is opened towards the head of the vehicle, in the running process of the electric vehicle, air entering the air way from the air inlet can be utilized for taking away heat of the battery pack, and therefore no energy needs to be additionally provided for cooling work of the cooling system for the electric vehicle battery pack, energy consumption is effectively reduced accordingly, and the mileage of the electric vehicle is prolonged.
Description
technical field [0001] The invention belongs to the technical field of heat dissipation systems, and in particular relates to a cooling system for electric vehicle battery packs. Background technique [0002] With the rapid development of electric vehicles, battery packs are one of the core components of electric vehicles, and their performance is directly related to the performance of electric vehicles. The battery pack of electric vehicles is sensitive to temperature changes. During use, excessive temperature will affect the performance of the battery and even cause safety accidents. Therefore, it is necessary to optimize the layout of the battery pack in the vehicle and design the battery pack cooling system. [0003] In the existing heat management system of the battery pack, the fan drives the air or the liquid pump drives the cooling liquid in the liquid pipe to dissipate heat from the battery pack. However, both air-cooled and water-cooled systems need to consume par...
