1. gas-phase plate type heat exchanger, it comprises the heat exchanger core body (2) in housing (1) and the housing (1), be provided with heat-insulation layer between housing (1) and the heat exchanger core body (2), it is characterized in that:

  • described heat exchanger core body (2) is made up of the mold pressing heat exchanger fin (3) that is arranged in parallel, each mold pressing heat exchanger fin (3) is the corrugated heat exchanger fin of two-way baffling disturbance for the cross section, weld together behind the inside backfin limit, both sides up and down of two adjacent mold pressing heat exchanger fins and constitute a heat exchange unit, in the middle of this heat exchange unit, promptly form the heat supply air chamber (4) that the heat supply gas level is flowed;

    And between the two adjacent heat exchange units, the right and left of the mold pressing heat exchanger fin (3) that each is relative also inwardly welds together behind the backfin limit, promptly forms the heated gas chamber (5) that makes the heated gas perpendicular flow between two adjacent heat exchange units;

    Weld the support member (6) that is used to support two heat exchange units at heated gas chamber (5) internal interval, described support member (6) cross section is roughly triangular in shape, and the triangle bipod is to two side edgefolds, and perhaps support member (6) cross section roughly is Ω

    shape;

    Housing (1) both sides are respectively equipped with heat supply air chamber import (7) and heat supply air chamber outlet (8), and communicate with the heat supply air chamber (4) of each unit of heat exchanger core body, housing (1) top is provided with heated gas chamber import (9), heated gas chamber outlet (10) and communicates with heated gas chamber (5) between each unit of heat exchanger core body.
