Document Type and Number:
WIPO Patent Application WO/2015/131834
Kind Code:
A1
Abstract:
A heat exchange plate for a plate-type heat exchanger and a plate-type heat exchanger provided with said heat exchange plate. The heat exchange plate comprises: an opening (11) used to form an end opening; a plurality of protrusions (12) arranged around at least a portion of the opening (11) along a circular line around the opening (11), the plurality of protrusions (12) protruding towards one side of a plate plane (15); transition portions (16) arranged between at least two neighbouring protrusions (12), the transition portions (16) being located on one side of the plate plane (15), and being a preset distance from the plate plane (15). The distance from the tops of the protrusions (12) to the plate plane is greater than the distance from the lowest points of the transition portions (16) to the plate plane. The present heat exchange plate and plate-type heat exchanger are provided with a relatively small end opening, can obtain a better fluid distribution between heat exchange fluid channels, and can obtain a better fluid distribution between heat exchange fluid channels even if a carbon dioxide refrigerant is used.
