1. An adaptive cooling allocation system for multiple motors, comprising:
a plurality of cooling groups, wherein each cooling group comprises a motor and a regulating valve, a cooling channel is arranged in the motor, and a liquid inlet channel and a liquid outlet channel are arranged in the regulating valve, respectively; an outlet end of the liquid inlet channel communicates with an inlet end of the cooling channel, and an outlet end of the cooling channel communicates with an inlet end of the liquid outlet channel; and
a main liquid inlet channel, wherein inlet ends of the plurality of liquid inlet channels communicate with the main liquid inlet channel, respectively;
a regulating channel is also arranged in the regulating valve; a valve block is arranged in the regulating channel, and extends into the liquid inlet channel, so that a regulating hole is formed between the valve block and the liquid inlet channel;
a temperature control regulating mechanism for controlling movement of the valve block based on temperature of a cooling medium in the liquid outlet channel is also arranged in the regulating channel, thereby performing differential cooling allocation on the plurality of cooling groups;
in an initial state, the regulating hole is in a minimum opening state; after the cooling medium flows, a position of the valve block remains unchanged according to the temperature of the cooling medium in the liquid outlet channel to maintain the minimum opening state of the regulating hole, or the temperature control regulating mechanism controls the movement of the valve block to increase opening of the regulating hole; and
the temperature control regulating mechanism comprises a temperature control driving component which can be deformed according to temperature changes and uses driving force generated by deformation to control the movement of the valve block.
