What is MRI Chiller and How Does It Work

2024-01-02

MRI Chiller is an essential component for the MRI machine. In order to operate normally, the MRI machine needs to be kept at a consistent, cool temperature. This is where the MRI chiller comes in. In this article, we will discuss what MRI chiller is and how it works.

What is MRI?

First, let's define what an MRI machine is. MRI is the abbreviation for Magnetic Resonance Imaging. It is a non-invasive medical imaging technique that uses strong magnetic fields and radio waves to generate images of the human body. MRI is used to diagnose a wide range of health conditions, including cancer, stroke, and neurological disorders.


During an MRI scan, the patient lies inside a giant cylindrical machine. A powerful magnetic field aligns the magnetization direction of hydrogen atoms in the body, and a radiofrequency field is applied to systematically change this alignment, causing the hydrogen atoms to produce a rotating magnetic field that is detected by the scanner. This signal can be manipulated with additional magnetic fields to build up enough information to construct an image of the body.


An MRI scan can be used to examine almost any part of the body, including the brain, spinal cord, bones, joints, breasts, heart and blood vessels, as well as internal organs such as the liver and lungs. They can be used to diagnose various medical conditions, guide certain treatment procedures, and monitor the progression of disease.

Now, let's discuss what MRI chiller is. An MRI chiller is a type of industrial water chiller that is specifically designed to keep the MRI machine cool. The chiller works by circulating chilled water through the MRI machine. This water absorbs the heat generated by the machine and carries it away, cooling the machine in the process.

There are two main types of MRI chillers:air-cooled and water-cooled chiller.As the names suggest, air-cooled chillers use air to cool the water, while water-cooled chillers use water. Air-cooled chillers are more common because they are easier to install and maintain. Water-cooled chillers, on the other hand, are more efficient, but they require water cooling tower ,so it is more complex installation and maintenance.


How Does MRI Chiller Work?

In terms of how an MRI chiller works, the process is relatively simple. The MRI chiller uses a refrigeration cycle to cool the water. The cycle consists of four main components: the compressor, the condenser, the expansion valve, and the evaporator. The compressor compresses the refrigerant gas, which raises its temperature. The hot gas is then passed through the condenser, where it is cooled by air or water. The cooled gas is then passed through the expansion valve, which reduces its pressure and temperature. Finally, the cool gas is passed through the evaporator, where it absorbs heat from the water. The process is then repeated, with the refrigerant gas returning to the compressor to complete the cycle.
