Abstract
A plate heat exchanger that is provided with an internal insert located between plates that form a channel. The insert takes the form of an additional plate that has guide channels with at least one inlet and one outlet which lead from one flow channel of one medium to another flow channel of the same medium. Sections of the additional plate that are free of guide channels are metallically connected to an adjacent heat exchanger plate. The guide channels are metallically connected to the other adjacent heat exchanger plate of the same channel.
Claims20
An improved plate heat exchanger for heat exchanging media in separate loops, wherein individual heat exchanger plates are stacked one upon the other and are metallically connected, the stacked plates each having openings that form flow channels for entry or discharge of a heating or cooling medium and other flow channels for other medium/media which are separate from each other and each is in fluid communication with channels between individual heat exchanger plates to thereby define separate loops consisting of flow channels interconnected by channels between the heat exchanger plates, the improvement comprising:
- at least one pair of adjacent heat exchanger plates having disposed in a channel an additional plate that is integrally secured at various regions thereof to each one of the pair of heat exchanger plates,
- the additional plate and pair of heat exchanger plates physically cooperating to establish at least one separate guide channel within the channel that exists between the pair of heat exchanger plates,
- the guide channel having at least one inlet and one outlet.
