Problems solved by technology

However, in the actual battery temperature field experiment, it is found that the battery temperature in the middle of the battery pack is relatively high, and the parallel ventilation structure, its wedge-shaped intake and exhaust channels are difficult to ensure the consistency of the battery pack temperature field distribution
In addition, this structure is not convenient for processing, and it is not easy to find problems in the debugging of the battery temperature field in real time during the online debugging system

Embodiment Construction

[0016] This cooling structure is shown in Fig. 3, Fig. 4 and Fig. 5, and it comprises accumulator group 1, air intake guide cover plate 3, accumulator support plate 5, accumulator bottom plate 4 and exhaust fan 8. The battery pack 1 is supported by the battery support plate 5 and is fixed on the battery base plate 4 . The wind guide cover plate 3 covers the battery pack 3 from the top and is fixed with the battery support plate 5 by connecting bolts 2 . It can be seen from Fig. 7 that there is an air intake guide groove 31 obliquely on the position corresponding to each single battery on the air intake guide cover plate 3, and the notches of the air intake guide groove 31 are obliquely opposite to the two rows of batteries. The gap between the groups, and the slot width K and diversion angle α of the air intake guide slot 31 gradually increase along the center of the battery pack to both sides, the slot width is between 10-20mm, and the intake guide slot 31 is 15-25° with the ...

Abstract

The heat elimination structure includes accumulator set, inlet air diversion cover board, support plate of floor plate of accumulator, and exhaust fan. Inlet air diversion trenches in oblique angle corresponding to positions of each single accumulator are made on the cover board. Inlet air diversion trenches in oblique angle are faced to gaps between accumulators. Width of trench, and angle of diversion are enlarged gradually from center of accumulator set to two sides. Being installed under floor plate, one exhaust fan is setup for one accumulator set. Exhausting diversion trenches cover exhaust fans. Being setup on accumulator set, temperature sensor through signal wire is connected to signal processing unit in the heat elimination system. Comparing with prior art, the invention keeps consistency of temperature among single accumulator so as to keep consistency of their performance. Features are simple compact structure, and easy of arrangement.

Description

technical field [0001] The invention relates to a heat dissipation structure of a power battery pack for a hybrid electric vehicle. Background technique [0002] The power battery is the key control component in the hybrid electric vehicle system, and its performance will affect the performance of the whole vehicle. The temperature field distribution of the power battery directly affects the service life of the battery, the main performance parameters of the battery and the imbalance between the battery modules. The research and development of the battery pack thermal management system is necessary for modern electric vehicles. The thermal monitoring and thermal monitoring of the battery pack Management is of great significance to the safety of vehicle operation. For example, "Highway Traffic Science and Technology" 2005 Issue 03, "Key Technologies of Electric Vehicle Battery Pack Thermal Management System" mentioned that Japan's Toyota's hybrid electric vehicle Prius and H...
