The invention discloses an aluminum alloy radiator and a surface cold copper spraying process, and belongs to the technical field of radiator machining. The preparation method comprises the following steps: selecting high-purity spherical copper powder, carrying out surface roughening pretreatment, impacting the copper powder on a substrate at a high speed of 300-800m / s by utilizing heating gas at 400-600 DEG C under the protection of inert gas, carrying out layered spraying for 3-8 times to form a 0.1-0.5 mm coating, and finally carrying out vacuum packaging. According to the method provided by the invention, the defects that the copper powder is easy to oxidize, the thermal damage of a matrix is large, the binding force of a coating is poor and the like in a thermal spraying process are effectively overcome. The oxidation rate of the prepared copper coating is lower than 1%, the porosity is smaller than 3%, the bonding strength reaches up to 40-80 MPa, the heat conductivity coefficient exceeds 380 W / (m.K), and the salt spray corrosion resistance exceeds 500 hours. The process has the advantages of low-temperature operation, energy conservation and environmental protection, the heat dissipation performance and reliability of the aluminum alloy radiator are remarkably improved, and the service life of the aluminum alloy radiator is remarkably prolonged.
