Embodiment Construction

[0028] A shell-and-tube heat exchanger, such as figure 1 As shown, the shell-and-tube heat exchanger includes a shell 20, a heat exchange component 23, a shell side inlet connection 21 and a shell side outlet connection 22; the heat exchange component 23 is arranged in the shell 20, and the heat exchange component It is fixedly connected to the front tube sheet 16 and the rear tube sheet 19; the shell-side inlet connecting pipe 21 and the shell-side outlet connecting pipe 22 are both arranged on the shell 20; the fluid enters from the shell-side inlet connecting pipe 21 and passes through the heat exchange components. For heat exchange, take over the outlet pipe 22 on the shell side to go out.

[0029] Preferably, the heat exchange component extends along the horizontal direction. The heat exchangers are arranged horizontally.

[0030] figure 2 A top view of the heat exchange component 23 is shown, as figure 2 As shown, the heat exchange component includes a central tube...

Abstract

The invention provides a loop heat pipe heat exchanger that switches the heat source according to the speed difference. The speed sensing element is arranged inside the free end of the tube bundle to detect the flow rate of the fluid in the free end of the tube bundle. The speed sensing element communicates with the controller connection, the controller extracts the flow velocity data according to the time sequence, and obtains the flow velocity difference or the accumulation of the flow velocity difference change through the comparison of the flow velocity data in adjacent time periods. Whether the second heat source is heating. The present invention judges the steady state of the fluid according to the speed difference or the accumulation of speed difference changes, so that the result is more accurate, and the problem of error increase caused by aging caused by the running time problem will not be avoided.

Description

technical field [0001] The invention relates to a shell-and-tube heat exchanger, in particular to a shell-and-tube heat exchanger with intermittent vibration descaling. Background technique [0002] Shell-and-tube heat exchangers are widely used in chemical, petroleum, refrigeration, nuclear energy and power industries. Due to the worldwide energy crisis, in order to reduce energy consumption, the demand for heat exchangers in industrial production is also increasing. The quality requirements for heat exchangers are also getting higher and higher. In recent decades, although compact heat exchangers (plate, plate-fin, press-welded plate heat exchangers, etc.), heat pipe heat exchangers, direct contact heat exchangers, etc. have been developed rapidly, but due to the The heat exchanger has a high degree of reliability and wide adaptability, and it still occupies a dominant position in output and consumption. According to relevant statistics, the current consumption of shell-a...
