Safety heat exchanger capable of monitoring leakage in real time

Abstract

The invention relates to a safety heat exchanger capable of monitoring leakage in real time. The safety heat exchanger comprises a cross-flow type shell and a heat exchanger core which is arranged in the cross-flow type shell, wherein a first fluid inlet, a second fluid inlet, a first fluid outlet and a second fluid outlet are respectively formed on a first sealing head, a second sealing head, a third sealing head and a fourth sealing head; a first vacuum layer sealing head is arranged at a joint of the first sealing head and the fourth sealing head; a vacuumizing device and a pressure detector or a material component detector are arranged on the first vacuum layer sealing head; a first vacuum layer is communicated with the first vacuum layer sealing head; a first fluid flow channel is respectively communicated with the first fluid inlet and the first fluid outlet; and a second fluid flow channel is respectively communicated with the second fluid inlet and the second fluid outlet. The safety heat exchanger capable of monitoring the leakage in real time is high in heat transfer efficiency, high in performance and high in equipment safety and can monitor the leakage situation in real time, and production safety and production quality are ensured.

Description

technical field [0001] The invention relates to the field of thermal equipment, in particular to a safety heat exchanger capable of real-time monitoring of leakage. Background technique [0002] At present, there are many kinds of heat exchangers. The plate-fin heat exchanger has high heat exchange efficiency, but due to its structural problems, internal leakage may occur between adjacent flow channels, resulting in the mixing of the two media. , which may cause equipment failure, damage, or even burnout. In addition, some media are high-pressure and toxic fluids. Once leaked, they will pollute the environment and even endanger personal safety. [0003] In some special occasions, once the fluids on both sides of the heat exchanger leak and come into contact, it is very likely to cause danger or cause a production safety accident. Finned heat exchangers in other forms lead to an increase in the volume and weight of the heat exchanger and an increase in cost. Contents of th...
