Abstract

According to an embodiment, a cooling device for cooling a constituent element housed in a housing of a unit subjected to an influence of a generated magnetic field includes a water cooling mechanism and at least one air cooling mechanism. The water cooling mechanism cools the constituent element by cooling a cooling plate with a flow of water flowing through a pipe passing through the cooling plate arranged in the housing. The air cooling mechanism is arranged on an outgoing side where the flow of water flowing through the pipe is outgoing from the housing and cools the constituent element by discharging air in the housing along with the water flow in accordance with the water flow.

First claim

What is claimed is:

1 . A cooling device for cooling a constituent element housed in a housing of a unit subjected to an influence of a generated magnetic field, the cooling device comprising:
a water cooling mechanism configured to cool the constituent element by cooling a cooling plate with a flow of water flowing through a pipe passing through the cooling plate arranged in the housing; and at least one air cooling mechanism arranged on an outgoing side where the flow of water flowing through the pipe is outgoing from the housing and configured to cool the constituent element by discharging air in the housing along with the water flow in accordance with the water flow.

2 . The cooling device according to claim 1 , wherein the air cooling mechanism suctions the air in the housing using a pressure difference between pressure of the air in the housing and pressure which decreases with a flow rate increased by making a flow channel of the water flow thinner.

3 . The cooling device according to claim 2 ,
wherein the water cooling mechanism is a plurality of pipes are arranged in the cooling plate, and wherein the air cooling mechanism is arranged on the outgoing side of the water flow in each pipe.

4 . The cooling device according to claim 2 , wherein a plurality of air cooling mechanisms are arranged on the outgoing side of the water flow in one pipe.

5 . The cooling device according to claim 2 , further comprising at least another air cooling mechanism configured to cool the constituent element by suctioning the air in the housing in accordance with a flow of water flowing through another pipe passing through the outside of the housing and discharging the suctioned air along with the water flow.

6 . The cooling device according to claim 2 , wherein the air cooling mechanism further includes a guide plate configured to guide the air in the housing toward a suction port for suctioning the air.

7 . The cooling device according to claim 1 , wherein the air cooling mechanism is an aspirator.

8 . The cooling device according to claim 7 ,
wherein the constituent element implements a function of a magnetic resonance imaging device, and wherein the unit for the constituent element housed in the housing is placed near a gantry device for generating a magnetic field in the magnetic resonance imaging device or in a room identical to a room where the gantry device is installed.

9 . The cooling device according to claim 8 , wherein the constituent element implements a function of a high-frequency amplification device configured to amplify an RF pulse to be radiated to a subject placed on a subject tabletop plate in the magnetic resonance imaging device.
