Conjunction state, the semiconductor refrigerating heating machine set enter cooling condition, i.e.,：The anode of the DC power supply connects the N-type half
The cathode of conductor and third metal heat-conducting plate, the DC power supply connects the P-type semiconductor and the second metal heat-conducting plate, in electricity
Under the action of, the difference of insulated cabinet internal-external temperature difference is utilized so that P-type semiconductor, N-type semiconductor point on the inside of the insulated cabinet
Node temperature not between second metal heat-conducting plate, third metal heat-conducting plate lowers, in free convection and radiation
Under effect, photo is cooled down, the second temperature probe continuously monitors the temperature T of the heat treatment sectionH, work as THEqual to ToutWhen,
The controller sends out signal instruction, and semiconductor refrigerating heating machine set is made to be stopped, and the mechanical driving device is the photograph
Piece placement screen work is sent to outlet section, and photo can outbound.
