Heat exchange structure suitable for motor pump

The invention relates to a heat exchange structure suitable for a motor pump. The heat exchange structure comprises a motor pump shell, an outer shell, a motor heat exchange sheath, a fixed sleeve, a movable sleeve, a piston sleeve, a piston and a spring; according to the device, a stream of high-pressure fluid is led from an outlet of the liquid cooling pump and enters the booster cavity through a spiral channel formed by the motor shell and the cylinder, the booster cavity is gradually filled with a working medium, and air in the booster cavity is discharged through a pipeline, so that the air in the booster cavity is prevented from being brought into the system during system medium circulation, and the service life of the system is prolonged. The system function is reduced; and cavitation of the liquid cooling pump occurs. And after the gas in the pressurizing cavity is completely exhausted, the working medium can enter the low-pressure cavity from the high-pressure cavity through the pipeline. And the med
