Cold plate

The utility model relates to a cold plate. A cold plate comprises a plate body and a floating pressure regulating cavity, a cold plate runner is arranged in the plate body and used for being communicated with an external circulating cooling device, the floating pressure regulating cavity is arranged in the plate body, a floating block is connected in the floating pressure regulating cavity in a sealed and sliding mode, and the floating block divides the floating pressure regulating cavity into a floating cavity and a follow-up cavity. The floating cavity is communicated with the cold plate flow channel, the floating block is driven to slide when pressure in the cold plate flow channel is increased, the size of the floating cavity is increased, and pressure compensation is provided for the cold plate flow channel. According to the cold plate, the floating pressure adjusting cavity is designed in the plate body, pressure compensation is provided for a cold plate flow channel, in the pressure relief process of t
