Abstract

The invention provides an antifreeze structure of a shell-and-tube heat exchanger, relates to the technical field of general heat exchange or heat transfer equipment, and solves the technical problem of how to slow down the impact force of a brine that freezes and expands on a heat exchange tube. The device includes a cylinder body and a plurality of heat exchange tubes, a brine is filled between the cylinder body and the plurality of heat exchange tubes, and a plurality of the heat exchange tubes are installed in the cylinder body; it is characterized in that, The inner wall of the cylinder is lined with an elastic layer, and the elastic layer slows down the impact force of the brine on the heat exchange tube due to freezing and expansion. The invention is used for chillers operating in low temperature environment.

Description

technical field [0001] The invention relates to the technical field of general heat exchange or heat transfer equipment, in particular to an antifreeze structure of a shell-and-tube heat exchanger. Background technique [0002] At present, the solution to the antifreeze problem of shell and tube heat exchangers in the market is basically to increase the electrical signal control to adjust the unit to achieve the antifreeze effect. Instead of taking antifreeze measures by changing the structure of the shell and tube heat exchanger itself. [0003] In the shell-and-tube heat exchanger used by chillers operating in low-temperature environments, the brine is filled between the cylinder and the heat exchange tubes in the heat exchanger. When the chiller is running or the power outage of the chiller is caused by unexpected reasons, the chiller will stop running. Due to the low ambient temperature (such as in a sub-zero temperature environment), the brine used inside the shell-an...
