The invention provides a loop heat pipe heat exchanger capable of switching heat sources according to the temperature difference. A first temperature sensor, a second temperature sensor and a third temperature sensor are correspondingly arranged in a left side pipe, a center pipe and a right side pipe and used for detecting the temperature in the left side pipe, the center pipe and the right side pipe; and a controller extracts temperature data of a left tube box, a right tube box and a middle tube box according to the time sequence, temperature differences or accumulation of temperature difference changes are obtained by comparing the temperature data of adjacent time periods, and when the temperature data is lower than a threshold value, the controller controls whether a first heat source, a third heat source and a second heat source perform heating or not. According to the loop heat pipe heat exchanger capable of switching the heat sources according to the temperature difference, the stable state of the fluid is judged according to the temperature difference or accumulation of temperature difference changes, so that the result is more accurate, and the problem of error increase caused by aging due to the running time problem is solved.
Description
Technical field [0001] The present invention relates to a housing heat exchanger, and more particularly to a housing heat exchanger for intermittent vibration descaling. Background technique [0002] The housing heat exchanger is widely used in chemical, petroleum, refrigeration, nuclear energy and power and other industries. Due to the world's energy crisis, in order to reduce energy consumption, there are more demand for heat exchangers in industrial production, The quality requirements for the heat exchanger are getting higher and higher. In recent decades, although a compact heat exchanger (plate, plate fin, pressure welding sheet heat exchanger, etc.), heat pipe heat exchanger, direct contact heat exchangers, etc., due to the housing The type heat generator has a high degree of reliability and extensive adaptability, which still occupies the dominance of yield and dosage. According to relevant statistics, the current industrial equipment is still used in the industrial devic...
