Problems solved by technology

When they are neatly arranged in the battery box, the cooling airflow entering from the outside will pass through the gap between the batteries unimpeded. Since the airflow can even travel in a straight line, it is not easy to be disturbed and generate turbulent vortices, which is effective with the surface of the battery. The contact area is small and the convective heat transfer is small, so the cooling efficiency is not high

Embodiment Construction

[0012] The battery arrangement of the present invention is shown in Figure 4 with 5 . looking sideways Figure 4 It can be seen from the figure that the No. 2 and No. 3 batteries are in close contact, so that most of the airflow can only pass through the gap between the No. 1 and No. 2 batteries and the gap between the No. 3 and No. The gap between the number and the wall passes through. When the airflow reaches the second layer of batteries (No. 5, No. 6, No. 7, and No. 8), due to the close contact between No. 5 and No. 6 batteries and between No. 7 and No. 8 batteries, the flow direction is forced to change, from Between No. 6 and No. 7 batteries and the gap between No. 5 and No. 8 batteries and the wall surface flows to the upper layer. In this way, the gaps are misplaced between the adjacent upper and lower layers, and except for some batteries on the wall, they are in close contact in pairs to hinder the direct passage of airflow. As a result, small eddies are conti...

Abstract

A method for arranging the battery in the cooling mechanism for electric vehicle is characterized by that in X direction, adjacent cells are a battery, the ends of two cells in same battery are closely contacted, and the batteries are arranged at intervals; in Y direction, adjacent cells are a battery, the sides of two cells in same battery are closely contacted, and the batteries are arranged atintervals; and in Z direction, the layers are arranged at intervals and batteries are staggered. Its advantages are large heat dissipating area and high heat dissipation effect.

Description

technical field [0001] The invention relates to an arrangement method for uniformly cooling multiple batteries installed on an electric vehicle, which belongs to the thermal management system of an electric vehicle [0002] technology field. Background technique [0003] With the rapid development of electric vehicles and the advancement of battery technology, the power of the battery pack is getting larger and smaller, and the corresponding heat generation is also increasing. How to efficiently dissipate heat and maintain the normal operating temperature of the battery is becoming increasingly urgent. . The battery packs in the existing electric vehicle battery box are all arranged regularly, such as figure 1 , 2 shown. When they are neatly arranged in the battery box, the cooling airflow entering from the outside will pass through the gap between the batteries unimpeded. Since the airflow can even travel in a straight line, it is not easy to be disturbed and generate t...
