Lithium bromide absorption type refrigerating device with impact and vibration auxiliary heat and mass transfer function

Abstract

The invention discloses a lithium bromide absorption type refrigerating device with an impact and vibration auxiliary heat and mass transfer function, and provide a refrigerating device capable of sucking mechanical energy into an absorber from outside and enabling a heat exchange pipe in the absorber to generate micro vibration, so that the film thickness is reduced; the heat and mass transfer coefficient effect is increased; and the absorption efficiency is improved. An impact and vibration device is connected on the absorber. The impact and vibration device comprises a guide pipe, a valve for vibration control and a spraying pipe; one end of the valve for the vibration control is connected with an outlet of the guide pipe, and the other end of the valve for the vibration valve is connected with an inlet of the spraying pipe; an inlet of the guide pipe is connected with a liquid outlet of the absorber or a shielding pump at the bottom of the absorber; an impact baffle is arranged on the heat exchange pipe of the absorber; and liquid sprayed from the spraying pipe impacts the impact baffle, so as to generate the micro vibration. The micro vibration is generated by the heat exchange pipe of the absorber through the impact and vibration device connected on the absorber, so that the film thickness is reduced, and the refrigeration effect is improved.

Description

technical field [0001] The invention relates to a lithium bromide absorption refrigerating device, in particular to a lithium bromide absorption refrigerating device with the function of shock vibration assisting heat and mass transfer.
