PURPOSE:To efficiently separate refrigerant liquid mist generated upon boiling of refrigerant liquid in a heat exchanger by providing a gas bleeding tube for externally guiding demister separate gas, a demister separate liquid drain tube provided at a bottom of a second partition chamber and a refrigerant liquid drain tube provided at a bottom of a first partition chamber as required. CONSTITUTION:A refrigerant fluid introducing tube 11 and a fluid-to-be-cooled flow tube 13 having a heat exchanging position 17 at a position lower than a height of a partition plate 4 through a first partition chamber 1 are provided in the chamber 1 of two partition chambers. A demister 21, a gas bleeding tube 22 for externally guiding demister separate gas and a demister separate liquid drain tube 23 at a bottom are provided in a second partition chamber 2 of the two chamber 5. A refrigerant liquid drain tube 12 is provided at a bottom of the chamber 1 as required. The two chambers are provided, the demister is provided in the second chamber thereby to efficiently separate refrigerant liquid mist in a heat exchanger, refrigerant gas is bled without accompanying the mist. |
