The invention relates to a performance testing device for a shell-and-tube heat exchanger. The device includes a pressure gauge, two pressure guide tubes, two dummy tubes and two temperature gauges. One end of the dummy tube is open, and the other end is a tube end. sealed, and the dummy tubes are provided with openings communicating with their interiors, the open ends of the two dummy tubes are fixed in the tube sheet of the shell-and-tube heat exchanger to be tested, and the outer walls of the two dummy tubes are in line with the The tube plate is sealed and connected, the openings of the two dummy tubes are respectively set on the inlet and outlet planes of the test area, and the probes of the two temperature instruments are respectively set on the inlet and outlet planes of the test area; It is connected with a pressure instrument, and the other end is respectively connected with the open ends of two dummy tubes; the invention realizes the performance test of the shell-side local pressure drop and heat transfer performance of the shell-and-tube heat exchanger; The local pressure drop and heat transfer performance of the shell side of the device cannot be analyzed and studied in detail.
Description
technical field [0001] The invention relates to the technical field of heat exchanger performance testing, in particular to a performance testing device for a shell-and-tube heat exchanger. Background technique [0002] The existing performance testing methods for shell-and-tube heat exchangers only place pressure gauges and temperature gauges at the inlet and outlet of the shell-and-tube heat exchanger to test the overall pressure drop and heat transfer performance of the heat exchanger. In fact, the shell-side flow and heat transfer characteristics of the shell-and-tube heat exchanger are very complex, and different local regions have different pressure drop and heat transfer performance. The local pressure drop and heat transfer performance of the shell side of the heat exchanger cannot be analyzed and studied in detail. Contents of the invention [0003] Aiming at the problems that the above-mentioned prior art only conducts performance tests on the whole heat exchang...
