Four-way pipe structure capable of realizing cross flow

The invention discloses a four-way pipe structure capable of realizing cross flow. The four-way pipe structure comprises a four-way pipe body, a transverse channel and a longitudinal channel, whereinthe transverse channel and the longitudinal channel are perpendicularly crossed; a partition plate for isolating the transverse channel from the longitudinal channel is arranged in the four-way pipe body, the partition plate obliquely extends upwards to the inner wall of the transverse channel, and the partition plate obliquely extends downwards to the inner wall of the longitudinal channel. Preferably, the extension inclination angle of the partition plate is set to be 15 to 35 degrees. Preferably, the inner diameter of the four-way pipe body is set to be 1.5 times that of a cooling pipeline.When a whole vehicle pipeline is designed and developed, under the condition that the pipeline trend meets the design requirement, the pipelines are prevented from crossing as much as possible, mutual friction and influence o
