The plate type of heat exchange device consists of a set of ripple stailess steel plate on which there are holes. The heat exchange occurs by the two flows passing through these holes. The plate is fitted between a frame plate and a pressure plate and is tightened by screws. There are seal washers at the plate to seal the channels and alternatively guide the flow to the channels. The plate number is subject to the physical performance and pressure difference and temperature program. The plate wrinkle promotes the turbulent current of the flow and play the support to the pressure difference of the plate. It serves at pharmacy and other liquor foodstuff and home position cleaning liquid and cooling and heating and pasteurization at some occasions.
