| 摘要 |
The invention relates to a heat exchanger device including a plate heat exchanger having a plate package of heat transfer plates. Between the plates there are first passages ( 18 ) for a heat transfer medium and second passages ( 19 ) for a cooling agent. Porthole channels ( 21 and 22 ) communicate with the first passages. Porthole channels ( 23 and 34 ) communicate with the second passages. The porthole channel ( 21 ) forms at least a part of an inlet channel ( 31 ) for the heat transfer medium. The porthole channel ( 22 ) forms at least a part of an outlet channel ( 32 ) for the heat transfer medium. The porthole channel ( 23 ) forms a part of an inlet channel ( 33 ) for the cooling agent. The porthole channel ( 24 ) forms a part of an outlet channel ( 34 ) for the cooling agent. A conduit ( 5 ) extends to the inlet channel ( 33 ) for supplying the cooling agent to the second passages. The conduit includes a conduit portion ( 6 ) extending into and out of the outlet channel ( 34 ) for the heat exchanger between the cooling agent in the conduit portion and the cooling in the outlet channel.
