Radiator

The utility model belongs to the technical field of heat dissipation, and particularly relates to a radiator which comprises a heat dissipation module, a plurality of heat exchange pipes are arranged in the heat dissipation module, the heat exchange pipes are arranged at intervals in the height direction of the heat dissipation module, each heat exchange pipe is provided with a heat absorption section and a heat release section, and the heat release sections are higher than the heat absorption sections. A phase-change heat-conducting medium is arranged in the heat exchange tube; the cold plate is connected to the heat dissipation module and makes contact with the heat absorption section, and a cavity is formed in the middle of the cold plate; the vapor chamber is arranged in a cavity in the middle of the cold plate and connected with the heat dissipation module, the vapor chamber is in contact with the heat absorption section, the heat dissipation effect of the radiator on a chip in an electronic device is be
