The invention provides a jet type condenser, which comprises a shell. A plurality of multilayered inner water chambers are arranged in the shell, multilayered outer water chambers which are correspondingly communicated with the inner water chambers are arranged outside the shell, each outer water chamber is communicated with a water source, the lower portion of the inner water chamber in a bottomlayer is an air-cooling area, and a water guiding tube which is communicated with the air-cooling area is arranged at the bottom of the inner water chamber of the bottom layer. The jet type condenseris characterized in that a transverse partition board is disposed in the inner water chamber of the bottom layer, the inner space of the inner water chamber of the bottom layer is divided into an upper cavity and a lower cavity which are independent, and correspondingly, the outer water chamber which corresponds to the inner water chamber of the bottom layer is also divided into two independent cavities which are respectively communicated with the two cavities of the inner water chamber of the bottom layer and respectively connected with the water source. The service range of the jet type condenser is expanded, when circulation water quantity is reduced in various seasons, jetting press heads of each row of sprayers can be guaranteed in the best range, the water quantity of the air-cooling area is guaranteed to be 5% of the total quantity of cooling water entering the jet type condenser under the work condition, condenser depression of condensate of the condenser can be remarkably reduced, running thermal consumption of a unit is reduced, and the jet type condenser is simple and feasible, and is convenient for large-scale popularization and use.
