Jet-type high-pressure fluid heat exchanger

The invention discloses a jet-type high-pressure fluid heat exchanger. The jet-type high-pressure fluid heat exchanger comprises a high-pressure jet flow nozzle, low-pressure transfer passages and a fluid mixing zone. An inlet of the fluid mixing zone has an inner cone-shaped structure and an outlet of the fluid mixing zone has a trumpet-shaped structure. An outlet of the high-pressure jet flow nozzle faces to an inlet of the fluid mixing zone. The multiple low-pressure transfer passages are uniformly distributed on an outer wall between the high-pressure jet flow nozzle and the fluid mixing zone. Each one of the low-pressure transfer passages forms an acute angle with the axle center of the high-pressure jet flow nozzle. The outer wall at the intersection of the low-pressure transfer passages and the fluid mixing zone is provided with an arc flow-disturbance zone. The jet-type high-pressure fluid heat exchanger can realize disturbance of low-pressure fluid by the arc flow-disturbance zone, reduces eddy, guar
