Abstract
The utility model discloses a plate-type heat exchanger with a secondary throttle. The plate-type heat exchanger with the secondary throttle comprises a front end plate and a rear end plate. Fluid interface channels are symmetrically arranged on the front end plate and the rear end plate. Heat exchanging plate sets are arranged between the front end plate and the rear end plate. The heat exchanging plate sets are sequentially piled up and comprise first heat exchanging plates and second heat exchanging plates. A distribution zone is arranged between a heat exchanging zone and a first flow guiding zone. A distribution zone is arranged between the heat exchanging zone and a second flow guiding zone. The plate-type heat exchanger with the secondary throttle boosts resistance generated when a cooling agent flows through a flow channel of the heat exchanging zone beside corner pores of an entry and an exit, reduces resistance generated when the cooling agent flows through a flow channel of the heating exchanging zone, enables the cooling agent to be evenly distributed on the surface of the whole heat exchanging zone and makes full use of area of the heat exchanging plate.
