Claim 7:
8. The electrical control system for minimally invasive tumor therapies according to claim 7, wherein the control module is further configured to:
determine, whether a tank pressure intensity of the refrigeration tank body reaches a fourth pressure intensity threshold value within a second preset duration, wherein the second preset duration is 1 minute and the fourth pressure intensity threshold value is 50 KPa;
control, if the tank pressure intensity of the refrigeration tank body does not reach the fourth pressure intensity threshold value, the vacuum tank liquid charging valve to open, so as to press a refrigeration working medium from the refrigeration tank body into the vacuum tank via the liquid conveying pipeline;
determine whether a vacuum tank pressure intensity sent by the vacuum tank pressure sensor is greater than a fifth pressure intensity threshold value, control, if the vacuum tank pressure intensity sent by the vacuum tank pressure sensor is greater than the fifth pressure intensity threshold value, the vacuum tank liquid charging valve to close, and open the auxiliary pressurization valve to increase a tank pressure intensity inside the refrigeration tank body, wherein the fifth pressure intensity threshold value is 1000 KPa; and
determine whether a tank pressure intensity of the refrigeration tank body is greater than a sixth pressure intensity threshold value, and control, if the tank pressure intensity of the refrigeration tank body is greater than the sixth pressure intensity threshold value, the auxiliary pressurization valve to close, wherein the sixth pressure intensity threshold value is 900 KPa.
