Flat pipe hydraulic plate and forming method and application thereof

The invention discloses a flat pipe hydraulic plate which comprises flat pipes arranged to be in a roundabout shape, every two adjacent flat pipes are communicated in parallel, a plurality of concave spoilers are arranged on one face of each flat pipe, the other face of each flat pipe is in a plane shape, and the spoilers enable fluid laminar flow in the flat pipes to be developed into turbulent flow. The flat pipe and the spoilers on the flat pipe are integrally hydraulically formed; at the position where the heat load position is large, the height of the flat pipe at the position is reduced, and the width of the flat pipe is increased to improve heat exchange; and at the position where the load position is low, the height of the flat pipe is increased, and the width of the flat pipe is reduced to reduce heat exchange. By arranging the spoilers on the flat tubes, arranging the spoilers on the surfaces, far away from the battery cells, of the flat tubes and not arranging the spoilers on the surfaces, in conta
