Cooling system for magnetic resonance imaging device having reduced noise and vibration

摘要

A conduit for the transfer of a cooling medium is provided that may include a tube that has a length and a through aperture that extends through the entire length. The tube may have an inner surface that defines a helical channel that may be continuous along a length of the tube such that the helical channel is continuous along a plurality of turns of the helical channel along the inner surface. The conduit may be incorporated into a cooling system of a magnetic resonance imaging device.

1. A cooling system for a magnetic resonance imaging device, comprising:
a compressor; a supply conduit in fluid communication with the compressor, wherein a cooling medium is transferred from the compressor through the supply conduit, wherein the supply conduit has a tube that has a through aperture and an inner surface that defines a helical channel that is continuous from a first turn of the helical channel to a second turn of the helical channel, wherein the helical channel has a concave shape, wherein the inner surface has a first convex portion located between the first turn and the second turn of the helical channel, wherein a width of the helical channel of the first turn is greater than a width of the first convex portion; a heat exchanger that receives the cooling medium from the supply conduit and heats the cooling medium; and a return conduit in fluid communication with the compressor, wherein the cooling medium is transferred through the return conduit to the compressor.
