The invention relates to a heat exchanger with a spiral baffle plate and a corrugated tube for liquid food sterilization. The heat exchanger comprises an outer sleeve, a heat exchange tube and the spiral baffle plate. The heat exchange tube is arranged in the outer sleeve and a cavity is formed between the inner wall of the outer sleeve and the outer wall of the heat exchange tube; liquid food, the flow direction of which is opposite to that of a heating fluid, is introduced into the heat exchange tube, and exchanges heat with the heating fluid to reach a sterilizing temperature, and the heatexchange tube is the corrugated tube, so that the flowing liquid food is disturbed continuously by cyclical fluctuation changes of expansion and compression; the spiral baffle plate is located in thecavity for increasing the flow rate of the heating fluid and forms a structure which increases the turbulence effect of the heating fluid together with the heat exchange tube. The heat exchanger playsefficient heating and ster
