Abstract

The invention provides a tube-shell type heat exchanger. The tube-shell type heat exchanger comprises a shell, wherein sealing heads are arranged at the two ends of the shell respectively, tube platesare arranged at the joints between the sealing heads and the shell, a heat exchange tube is connected with the tube plates at the two ends, the shell comprises a hot water inlet and a hot water outlet, the hot water inlet and the hot water outlet are connected with a hot water inlet pipe and a hot water return pipe respectively, the hot water inlet pipe and the hot water return pipe are providedwith a plurality of connecting points, a heat preservation layer is arranged outside the connecting points, and the tube-shell type heat exchanger is characterized in that a thermal imager is arrangedat the at least one connecting point. According to the tube-shell type heat exchanger, the good energy-saving and environment-friendly effects can be achieved.

Description

technical field [0001] The invention relates to a shell-and-tube heat exchanger, in particular to a shell-and-tube heat exchanger for leak detection. Background technique [0002] Shell and tube heat exchanger is also called shell and tube heat exchanger. It is a partitioned wall heat exchanger that uses the wall of the tube bundle enclosed in the shell as the heat transfer surface. This kind of heat exchanger has simple structure, low cost, wide flow cross-section, and easy to clean scale; but it has low heat transfer coefficient and occupies a large area. It can be made of various structural materials (mainly metal materials), and can be used under high temperature and high pressure. It is the most widely used type at present. The leakage of the shell and tube heat exchanger will directly lead to the loss of a large amount of high-temperature medium in the tube, which will pollute the environment. [0003] At present, there are not many research projects on heat exchang...
