Battery box internally provided with independent heat-dissipating channel and battery box body

Abstract

The invention relates to the field of new energy automobiles and provides a battery box internally provided with an independent heat-dissipating channel and a battery box body, and solves the problemthat the heat-dissipating efficiency of the battery box in the prior art is low. The battery box internally provided with the independent heat-dissipating channel comprises a battery box body and a battery pack arranged in the battery box body. An air inlet and an air outlet are formed in the battery box body, a battery bracket is arranged in the battery box body, a battery pack mounting cavity and an air flue communicating to the air inlet and the air outlet are separately formed on two sides of the battery bracket, more than two branched tuyeres are formed on the battery bracket, the independent heat-dissipating channels are arranged at the branched buyers, the battery pack is arranged in the independent heat-dissipating channel, and a channel through which an air flow circulates is arranged between the battery pack and the inner wall of the heat-dissipating channel and/or a channel through which an air flow circulates is arranged between the battery units is arranged in the batterypack. The air flow is guided in the channel to dissipate heat of the battery pack in the whole channel, so that the heat-dissipating efficiency is improved.

Description

Technical field [0001] The invention relates to a new energy vehicle, in particular to a battery box with built-in independent heat dissipation channels and a battery box body thereof. Background technique [0002] Under the guidance of national policies, the scale of domestic new energy vehicle R&D and production is increasing, and the total energy of batteries installed in new energy vehicles is also increasing to meet higher market requirements. In the current process of battery manufacturing and use, the outstanding problems are: the weight of the battery is large, the volume is large, the charging is slow, and the safety of the battery. The above aspects all involve the technology to cool the battery. . In the prior art, the heat dissipation structure in the battery box is relatively simple, and the battery pack is only placed in the box body with the air inlet and the air outlet, the heat dissipation effect is poor, and the heat dissipation is uneven. [0003] The authorize...
