Temperature control assembly, discrete heat source convection control device and control method

The invention discloses a temperature control assembly, a discrete heat source convection control device and a control method.The temperature control assembly comprises a temperature control plate, a heat preservation plate and a plurality of heat conduction columns, the heat conduction columns are all connected to the temperature control plate and are distributed on the temperature control plate in a discrete mode, and the heat conduction columns penetrate through the heat preservation plate; the end, away from the temperature control plate, of the heat conduction column is flush with the surface, away from the temperature control plate, of the heat preservation plate. Heat or cold of the temperature control plate can only be transmitted through the heat conduction columns, on the side close to the interior of the box body, the heat conduction columns are the preset heating temperature or preset refrigerating temperature of the temperature control plate, and the temperature of the area where the heat conduct
