Engine radiator with cooling pipes convenient to splice

The invention discloses an engine radiator with cooling pipes convenient to splice. The engine radiator comprises a radiating shell. The heat dissipation core pipe is symmetrically arranged between the inner walls of the heat dissipation shell, and the two ends of the heat dissipation core pipe are connected with a first valve set and a second valve set respectively; the heat dissipation core tube comprises core tube single pieces and a combined sleeve, the core tube single pieces are connected end to end through the combined sleeve, and the first valve set and the second valve set are connected to the ends of the core tube single pieces respectively. The heat dissipation panel is composed of the heat dissipation core pipes in the corrugated overlapping shape, the heat dissipation panel is divided into the upper water path and the lower water path to guarantee the change of the cooling effect, a cold water curtain structure is formed from top to bottom, when heat is large, circulation of the upper water path
