Abstract
A refrigerant phase change monitoring device applied to an IBGT module installation area comprises a heat conduction plate, a transparent plate and a pressing plate which are laminated together from bottom to top. The upper surface of the heat conduction plate is provided with a refrigerant sealing flow path allowing refrigerant to flow through, an IBGT module is installed on the lower surface, corresponding to the refrigerant sealing flow path, of the heat conduction plate, a refrigerant inlet and a refrigerant outlet of the refrigerant sealing flow path are both formed in the side face of the heat conduction plate, the pressing plate is provided with a hollowed-out monitoring viewport corresponding to the refrigerant sealing flow path, and sensing devices used for monitoring the pressure and temperature of the refrigerant are installed at the refrigerant inlet and the refrigerant outlet of the refrigerant sealing flow path respectively. According to the refrigerant phase change monitoring device applied to the IBGT module installation area, the refrigerant is utilized for absorbing heat generated during work of the IBGT module, the whole refrigerant phase change process is visual while the work temperature of the IBGT module is lowered, and the pressure and temperature of the refrigerant before and after heat absorption are effectively monitored. The invention further provides a refrigerant phase change monitoring method applied to the IBGT module installation area.
Description
technical field [0001] The invention relates to a refrigerant phase change monitoring device, in particular to a refrigerant phase change monitoring device applied to an IBGT module installation area, which is used to monitor the process of refrigerant absorbing heat and undergoing phase change. The invention also relates to a refrigerant phase change monitoring method applied to the installation area of the IBGT module. Background technique [0002] In the refrigeration industry, two methods are usually used to observe the phase change process of the refrigerant in the pipeline. One is to set up a transparent cylindrical observation room connected in series with the pipeline somewhere in the straight section of the pipeline to observe the phase change of the refrigerant here. ; One is to install a phase-change sight glass somewhere in the straight line of the pipeline in series to observe the phase change of the refrigerant in the pipeline. These two observation features...
