The traditional heat dissipation technology cannot meet the increasing power heat dissipation requirement, and at present, the relatively good heat dissipation technology can be a temperature equalizing plate, and the temperature equalizing plate is a heat dissipation device, so that heat can be taken away quickly in work, and the heat can be prevented from being concentrated on a heat source. The structure of the temperature equalizing plate is approximately two upper and lower radiating plate bodies, and the heating area and the radiating area inside the temperature equalizing plate are covered. Because its inside needs the evacuation, consequently the welding quality and the sealing quality of two blocks of plate bodies are crucial, and the welding process is usually for after the edge of two blocks of plate bodies about sets up the solder, high temperature press welding forms, and the quality of welding process will directly decide the quality of monoblock samming board. The problem that an upper sheet and a lower sheet are difficult to position generally exists in the industry, and is mainly reflected in that the difference between the thermal expansion coefficients of a copper alloy of a temperature equalizing plate and a graphite material of a welding mold is large in the welding process, the copper alloy of the temperature equalizing plate and the graphite material of the welding mold cannot be synchronized at high temperature, and when the temperature equalizing plate is blocked by the graphite mold with small expansion degree due to large thermal expansion degree, bulging and deformation are easy to generate, so that poor welding is caused, and therefore a temperature equalizing plate welding mold with good welding quality and high efficiency is urgently needed at present.
