Abstract

The invention discloses a liquid homogenizing board for a flooded evaporator and the flooded evaporator. Multiple liquid homogenizing holes are formed in the liquid homogenizing board and distributed in the liquid homogenizing board in an inhomogeneous manner, so that the hole opening area in the unit area of the position, which bears the large fluid pressure, below the liquid homogenizing board is smaller than that in the unit area of the position, which bears the small fluid pressure, below the liquid homogenizing board, and / or the hole opening area in the unit area of the position, with the small fluid resistance, above the liquid homogenizing board is smaller than that in the unit area of the position, with the large fluid resistance, above the liquid homogenizing board. The flooded evaporator comprises a shell, the liquid homogenizing board and heat exchange pipes. The liquid homogenizing board is arranged in the shell and located above the bottom of the shell. The heat exchange pipes are arranged between the shell and the liquid homogenizing board. The liquid homogenizing board is mentioned above. Due to the fact that the hole opening manner of the multiple liquid homogenizing holes in the liquid homogenizing board is reasonably set, the flow of fluid is more reasonably distributed.

Description

technical field [0001] The invention relates to the field of heat exchange equipment, in particular to a liquid equalizing plate of a flooded evaporator and a flooded evaporator. Background technique [0002] Flooded evaporators are generally used in refrigeration systems. The heat exchange tube of the flooded evaporator is water, and the refrigerant evaporates outside the heat exchange tube, so the heat transfer surface is basically in contact with the liquid state, and the refrigerant liquid flows out through the fluid outlet on the top of the shell after absorbing heat and vaporizing. The flooded evaporator has compact structure, convenient operation and management, and high heat transfer coefficient. [0003] Figure 1 to Figure 3 The structure of a first prior art flooded evaporator is shown. in, figure 1 It is a structural schematic diagram of the first flooded evaporator in the prior art. figure 2 yes figure 1 Schematic diagram of the M-M cross-sectional struc...
