Abstract

The invention discloses a cooling apparatus and a cooling method for a magnetic resonance imaging device. The magnetic resonance imaging device comprises a magnet disposed in a sealed space filled with refrigerant. The cooling apparatus comprises a primary cooling apparatus (10), a secondary cooling apparatus (20), a sensor (30), and a controller (40). The controller can control the secondary cooling apparatus (20) based on the operating state and the value and trend of the air pressure within the sealed space. The secondary cooling apparatus (20) has a plurality of output powers. When the operating state is a state other than a scanning state, the secondary cooling apparatus (20) operates at a second output power lower than that when the operating state is the scanning state. The coolingapparatus can adjust the output power of the secondary cooling apparatus when the magnetic resonance imaging device is in a state ready to scan, a standby state / a off state. According to the cooling apparatus and the cooling method of the magnetic resonance imaging device, the energy can be saved, the life of the secondary cooling device can be extended, and the use costs can be saved.

Description

technical field [0001] The present invention relates to a cooling device, especially a cooling device for magnetic resonance imaging equipment, and a cooling method using the cooling device. Background technique [0002] In magnetic resonance imaging equipment, the magnet generates a lot of heat during operation. To ensure normal operation, primary cooling devices (Primary Cooling Device, PCD) such as cold heads and helium compressors, and secondary cooling devices such as water cooling devices are required. Secondary Cooling Device (SCD) constitutes a cooling system to export heat, and at the same time, the secondary cooling device can also cool other heat-generating components of the MRI equipment. State, in different operating states, the heat generation of each heating component is different. When the MRI equipment is not scanning, if the secondary cooling device is always in full load working state, the energy consumption will be very high, which will cause unnecessary ...
