Abstract
A plate type heat exchanger with low flow resistance at grooves of angle holes and secondary seals is mainly characterized in that: seal structures of two pairs of four angle holes which designed in pairs at the two ends of heat-exchanged structures of each heat-exchanged plate and in the corresponding secondary seal structures of two pairs of totally four angle holes, the seal structures of different pairs of angle holes and the corresponding secondary seal structures of angle holes, wherein bottom layers of grooves bearing seal gaskets are in a different horizon. When heat-exchanged plates are fixed one by one, a flue channel consisted by seal gasket grooves of angle holes and the corresponding secondary seal gasket grooves between plates is higher than the space between concavo-convex corrugations, thereby enlarging the cross-sectional area of the flue channel and reducing the flow resistance generated by heat-exchanged media flowing here.
Description
Technical field
The utility model relates to a kind of plate type heat exchanger, relates in particular to a kind of plate type heat exchanger that seals with gasket seal.
