Description

TECHNICAL FIELD

[0001] The utility model relates to heat exchanger field especially a heat exchanger with water leakage early warning. BACKGROUND

[0002] High temperature fluid and low temperature fluid in the box type heat exchanger carry out indirect contact heat exchange through solid wall surface. Heat is transferred from the high temperature fluid to the wall surface, and then is transferred to the low temperature fluid from the wall surface, so that heat exchange and transmission are realized, the purpose of heating or cooling fluid is achieved. Two surface type heat exchanger are connected by heat carrier circulating in it, the heat carrier circulates between the high temperature fluid heat exchanger and the low temperature fluid, and heat transmission is realized.

[0003] When the heat exchanger leaks, the joint is the part prone to water leakage. Since the heat exchanger is connected with the pipeline outside, the flange is generally used for connection, and the flange connection is sealed by the gasket between the flange surfaces relying on the bolt fastening. If the bolt fastening force is uneven, the gasket will be unevenly stressed, and the seal in some areas will be loose. The gasket will age, deform and be damaged after long-term use, and lose the sealing performance, so that the fluid leaks from the flange joint. The prior art cannot collect the liquid leaked from the joint and give an early warning. Water leakage at the joint will reduce the heat exchange efficiency between the cold and hot fluids in the heat exchanger. For example, in a tubular heat exchanger, if the fluids in the tube and shell leak through the joint and mix with each other, they cannot fully transfer heat according to the designed process, so that the temperature of the outlet fluid cannot reach the expected value, affecting the effect of the entire heat exchange process.
