Specific embodiment
In conjunction with Fig. 1, Fig. 3, a kind of novel plate heat exchanger plate of fishbone, including plate main body is set in plate main body
Set location hole 1, corner apertures 2, guiding region 3, shunting zone 4, heat transfer zone 5.Play the work of positioning in the both ends that location hole 1 is located at plate main body
With.There are four being located on four angles of plate main body, heat transferring medium flows through corner apertures 2 from corner apertures 2.Guiding region 3 will exchange heat
Medium is guided to shunting zone 4.Heat transferring medium is branched to the different region in heat transfer zone 5 by shunting zone 4.It is situated between on heat transfer zone 5 along heat exchange
Mass flow to setting ripple 11.
When heat transferring medium flows into plate by corner apertures 2, by guiding region 3 and shunting zone 4, inflow heat transfer zone 5 is being provided with
It is that heat exchange is carried out on heat transfer zone 5 on the plate of ripple.Fluid after heat exchange flows at the corner apertures of the other side, converges inflow
