And the energy absorption box is provided with an energy absorption crumple slot.
The cooling liquid of the cooling system of the automobile flows into the main beam through the medium interface of one side connector and then flows out from the medium interface of the other side connector, and a pressure difference exists between the medium interfaces of the two side connectors.
As shown in fig. 3, the main beam is formed by welding and connecting a first curved beam, a second curved beam, a third curved beam and a third curved beam.
