The invention discloses a liquid cooling radiator for a server, and the radiator comprises a heat dissipation cold head which is disposed on a heating element of the server; the heat dissipation cold head comprises an upper cover plate and a lower cover plate, a hollow lower cover plate cavity is formed in the lower cover plate, and first cooling fluid is injected into the lower cover plate cavity; the upper cover plate and the lower cover plate are connected with each other to define a second cooling fluid cavity, and second cooling fluid is introduced into the second cooling fluid cavity; the first cooling fluid circulates in the lower cover plate cavity and exchanges heat with the second cooling fluid in the second cooling fluid cavity, and at least part of the first cooling fluid is subjected to phase state transformation to dissipate heat of the server. According to the invention, two modes of phase change cooling and convection cooling are combined, so that the cooling efficiency of the server is greatl
