  • Publication number: 20170219296
    Abstract: Disclosed are a heat exchange plate (10) and a plate-type heat exchanger using the heat exchange plate (10). The heat exchange plate (10) comprises: a body; pits and/or protrusions (3), arranged on the surface of the body in predetermined patterns; and a plurality of adjusting portions (1, 2), wherein four quadrangular adjusting portions (1, 2) are arranged at the periphery of each pit and/or protrusion (3), then a basic heat transfer unit (4) is formed by each pit and/or protrusion (3) and the adjusting portions (1, 2) at the periphery thereof, and the adjusting portions (1, 2) in each basic heat transfer unit (4) are arranged to be provided with relatively large gaps in a main flow direction (D 1) of fluid on the heat exchange plate (10) and are arranged to be provided with relatively small gaps in an auxiliary flow direction (D2) of the fluid on the heat exchange plate (10).

  • Publication number: 20170067695
    Abstract: A heat exchange plate used for a plate-type heat exchanger. The heat exchange plate comprises: a heat exchange part (10); multiples protrusions (14) that protrude from a plate plane (12) to at least one side of the plate plane (12) in the heat exchange part (10), the multiple protrusions (14) being aligned along multiple lines; and a transition part (16) that is between adjacent protrudes (14) aligned along a line and that protrudes to at least one side of the plate plane (12), the size of the top of each protrusion (14) in a direction perpendicular to the line being larger than the size of the top of the transition part (16). Strength of the heat exchange plate of the plate-type heat exchanger is improved by increasing the size of a welding part or a bearing part.

  • Publication number: 20170016680
    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 along 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.

  • Publication number: 20160356560
    Abstract: A board-type heat exchanger comprises multiple heat exchange boards (10) overlapped with each other. Each of the heat exchange boards (10) comprises a fluid inlet (1) and a fluid outlet (2) that are separately located in two opposite ends of the heat exchange board in the lengthwise direction. A partition portion is disposed on the upper surface and/ or the lower surface of each of the heat exchange boards (10), so that fluid from the fluid inlet (1) is divided at the fluid inlet (1), then flows into independent fluid passage zones (3, 4) partitioned by the partition portion, gathers at the fluid outlet (2), and finally flows out of the fluid outlet (2).

  • Publication number: 20160341484
    Abstract: A heat exchanging board (1) and a board-type heat exchanger provided with the heat exchanging board (1). The heat exchanging board (1) comprises a board main body (11). Multiple recessed portions (12) and multiple raised portions (13) are disposed on the surface of the board main body (11). The multiple recessed portions (12) and the multiple raised portions (13) are disposed in a staggered manner along a first direction (51) and are disposed in a staggered manner along a second direction (S2) perpendicular to the first direction (S1). Top portions of the multiple raised portions (13) are provided slender forms along the first direction (S1). The heat exchanging board (1) and the board-type heat exchanger provided with the heat exchanging board (1) can ensure good strength of the heat exchanger in the case of ensuring the heat exchanging efficiency, and can reduce manufacturing cost of the heat exchanging board (1).
