Some row's isolation bars, are used for controlling flow direction, and described import department's bit stream road converges district, exit site runner converges district and runner
Turning converges and is provided with zigzag fin between both sides, district, inner housing and shell body, described zigzag fin be arranged on inner housing or
On shell body, described zigzag fin is multiple rows of independent fin.
The further technical scheme of the present invention is, described water inlet and outlet position are vertically or horizontally arranged.
The further technical scheme of the present invention is, the axis of described water inlet and outlet is all vertical with the surface of inner housing
Directly.
The further technical scheme of the present invention is, described import department's bit stream road converges district and exit site runner converges district
It is provided with flow distribution plate.
The further technical scheme of the present invention is, the turning of described runner converges district and is arranged on inner housing and import department
Bit stream road converges district and converges, with exit site runner, the side that district is relative.
The further technical scheme of the present invention is that described isolation bar is for vertically or horizontally to arrange.
The further technical scheme of the present invention is, described isolation bar quantity is single row or multiple rows.
The further technical scheme of the present invention is, runner is divided into structure in parallel or series by described isolation bar.
