Description
Technical Field
The invention relates to the technical field of evaporators, in particular to a refrigerant two-phase mixed flow liquid inlet uniform distribution device and application thereof.
Background
The evaporator is one of the key components in a refrigeration system, and its performance determines the performance of the entire refrigeration system. The low-temperature and low-pressure gas-liquid mixed refrigerant enters the evaporator, exchanges heat with the outside air (or secondary refrigerant, such as water, glycol and the like), is gasified to absorb heat, and achieves the aim of refrigerating the air (or the secondary refrigerant). The evaporator is of various types, mainly including tube fin type, shell and tube type, flooded type, parallel flow type, plate fin type and the like. The plate-fin evaporator is a relatively new evaporator form, mainly utilizes fins and partition plates to construct medium channels, and then welds the channels in a stitch welding mode according to different flowing modes of fluid to obtain an evaporator core body (also called as a plate bundle), so that the plate-fin evaporator can be used as a gas-gas, gas-liquid and liquid-liquid alternate heat exchange place and is suitable for various flow field conditions such as concurrent flow, countercurrent flow, cocurrent flow or wrong countercurrent flow.
In the industrial practical application process of the plate-fin evaporator, the most common problem is the blockage of the medium channel, which is usually caused by that large-diameter medium particles doped in the fluid entering the channel are gathered at the end fin or the turning part of the medium channel, so that the fluid cannot smoothly pass through the channel to cause blockage, and it is calculated that the blockage can not occur in 1/4 with the diameter of the medium particles being smaller than the inner diameter of the tube. An effective solution to this problem is to take some filtering action or to cause the particulate laden media to settle out at the entrance of the channel before the fluid enters the media channel. In addition, if the flow rate at a certain position of the medium channel is too large, the leakage of the channel is easily caused, so that the problem of uneven distribution of the fluid is solved, and the excessive instantaneous flow rate at a certain position is avoided.
