Title:
HEAT EXCHANGE PLATE OF PLATE-TYPE CONDENSER
Document Type and Number:
WIPO Patent Application WO/2021/203666
Kind Code:
A1
Abstract:
Disclosed is a heat exchange plate of a plate-type condenser. The heat exchange plate is formed by welding edges of two plate bodies, an inlet and an outlet which are connected to an inner cavity of the heat exchange plate are welded to the edges of the plate bodies, and a plurality of baffle lines are arranged on the plate bodies to form a circulating baffle flow channel. Round and oval salient points are arranged in a flow channel area to disturb a flow and enhance heat exchange. The round salient points not only enhance the pressure resistance of the flow channel, but also play a role in disturbing a flow, and the oval salient points improve the dynamic performance of a medium flow channel. The heat exchange plate is manufactured by using two methods, one of which involves firstly carrying out rolling forming and then carrying out resistance welding at the salient points of the plate bodies, and the other of which involves firstly carrying out fixed-point welding on two stacked plate bodies and then carrying out forming by means of blowing. The round and oval salient points of the present invention not only enhance heat exchange, but also increase the mechanical strength of the plate bodies; and the heat exchange plate of the plate-type condenser has a compact structure, is easy to assemble, is resistant to high temperatures and high pressure, has a high heat exchange efficiency, and has a long service life.
