Technical Field

[0001] The present application relates to the technical field of heat exchange devices, and in particular to a monitoring device and system for a heat exchange unit and a heat exchange unit. Background Art

[0002] In modern medical equipment, heat exchangers such as helium compressors are critical components, which can be used in MRI systems, etc. If the helium compressor water supply temperature is overheated, the MRI system will not work or the liquid helium will evaporate, which will cause serious economic losses.

[0003] In the prior art, once a problem occurs in a heat exchanger unit, the manufacturer is contacted through the hospital to report the problem, and the manufacturer rushes to the site for repair after receiving the report. The whole process usually takes about 24 hours. In addition, in order to reduce the failure rate, the manufacturer will increase the number of active inspections and strengthen maintenance and maintenance work.

[0004] Although existing technologies have improved the reliability of heat exchangers to a certain extent, since maintenance takes a certain amount of time, the unit problem may further deteriorate while waiting for maintenance, and the heat exchanger cannot operate, causing the MRI system to shut down and not work properly. In order to avoid this situation, manufacturers can only be forced to increase the number of active inspections to ensure the normal operation of the unit.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application. In the event of any inconsistency, the meaning described in this specification or the meaning derived from the contents recorded in this specification shall prevail. In addition, the terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application. In order to accurately describe the technical content in this application and to accurately understand the present application, the following explanations or definitions are given to the terms used in this specification before describing the specific implementation methods:

[0037] 1) HC supply water temperature: refers to the temperature of the supply water flowing from the heat source into the heat exchange unit.

[0038] 2) Secondary supply water pressure: refers to the pressure of water entering the building or equipment from the outlet of the heat exchange unit. It is provided by the high-pressure pump in the HC water supply system and can be adjusted according to demand to ensure stable water supply.

[0039] 3) Secondary return water pressure: refers to the pressure of water flowing back to the heat exchange unit from the return port of the equipment. It is usually lower than the secondary water supply pressure because water will experience pressure loss during use.

[0040] The monitoring scheme of the heat exchange unit provided in the embodiment of the present application is particularly suitable for and targeted at medical heat exchange units. The monitoring scheme of the heat exchange unit provided in the present application is introduced below in conjunction with a specific embodiment.
