Abstract

The invention discloses a heat exchanging plate of plate type heat exchanger, belonging to the parts of heat exchanging equipment with no directly contacting heat exchanging medium, especially the parts of heat exchanging equipment which is used for fixed plate or laminating channel of two exchanging mediums and in which each medium is not contacted with different side face of the channel. The heat exchanging plate comprises locating hole, in-off hole of medium, guiding region of in-off hole, diverge region, and heat conducting region. It is characterized in that plate ripple in the heat conduction region is divided into two sides by the plate central line, one side is ripple with blunt angle and the other side is ripple with acute angle. The benefit of invention is because ripples with different angle are applied in the plate by the plate central line, the flux of heat exchanging amount is matched with permitted pressure-drop better. Meanwhile, because the path diameter ratio of ripples on two sides of heat exchanging plate is different, velocity of flow of cool and heat medium is approach or equal among plates and the heat exchanging coefficient is improved by 5-10%. The invention is applied in the update of original production.

Description

technical field [0001] The invention belongs to parts of heat exchange devices in which the heat exchange media are not in direct contact, in particular to fixed plates or laminated channels for two exchange media, parts of heat exchange devices in which the media are in contact with different sides of the channels . Background technique [0002] The plate heat exchanger is a high-efficiency heat exchange equipment with a metal corrugated plate as the heat transfer element. The corrugations in the heat exchange plate adopt a symmetrical design, that is, the angles of the corrugations on both sides of the center line of the same plate are the same, so although the manufacturing process is simple , but in the usual heat exchange state, the flow rate of the hot medium and the cold medium are different, and two kinds of plates with different angles are used to cross each other for assembly. Many molds are needed in the manufacture, and it is not easy to operate in the assembly. ...
