Problems solved by technology
In related technologies, most of the radiators are arranged at the position of the air intake grille in front of the vehicle, and at the same time, a fan with a large air intake volume is installed to increase the air intake area to dissipate heat from the engine. However, the above methods cannot meet the heat dissipation requirements of high-power engines. , especially in extreme conditions, the normal operation of the engine cannot be guaranteed

The invention relates to an engine heat dissipation system, a vehicle and an engine heat dissipation method. The engine heat dissipation system comprises a main heat dissipation device arranged in front of the vehicle and an auxiliary heat dissipation device connected with the main heat dissipation device and arranged at the bottom of the vehicle. The auxiliary heat dissipation device comprises anauxiliary heat dissipater fixed to the bottom of the vehicle, an air-inlet grille used for sealing the auxiliary heat dissipation device and a first controller used for controlling the air-inlet grille to open or close. The main heat dissipation device and the auxiliary heat dissipation device are matched, and especially under the limiting condition that the main heat dissipation device cannot meet the heat dissipation requirement of an engine, the auxiliary heat dissipation device can conduct supplementary heat dissipation; due to the fact that the auxiliary heat dissipation device is arranged at the bottom of the vehicle, flowing air in the traveling process of the vehicle is fully used for dissipating heat, and the first controller controls the air-inlet grille to open or close so as to meet the heat dissipation requirements of the engine under different working conditions; and the auxiliary heat dissipation device is arranged at the bottom of the vehicle, so that the arrangement space at the bottom of the vehicle is fully used, and the structure is more compact.
Description
technical field [0001] The present disclosure relates to the field of engine heat dissipation, and in particular, relates to an engine heat dissipation system, a vehicle, and an engine heat dissipation method. Background technique [0002] Engine heat dissipation, especially the heat dissipation of fuel cell vehicle engines, is one of the difficulties in vehicle development. In related technologies, most of the radiators are arranged at the position of the air intake grille in front of the vehicle, and at the same time, a fan with a large air intake volume is installed to increase the air intake area to dissipate heat from the engine. However, the above methods cannot meet the heat dissipation requirements of high-power engines. , especially in extreme conditions, the normal operation of the engine cannot be guaranteed. Contents of the invention [0003] The first object of the present disclosure is to provide an engine heat dissipation system, which can meet the heat dis...
