However, this solution still causes a lot of liquid refrigerant to fly, since the air flow rate at the inlet of the baffle still reaches 2 m/s, and in order to reduce the air flow rate, only the height of the baffle can be reduced, firstly the evaporator space is reduced, and secondly the baffle is close to the pool surface, and still liquid refrigerant is easily carried away; in terms of refrigerant charge, the flooded charge is greatest. Because the ship can shake, the liquid of the flooded evaporator can be easily shaken out in the running process, and the existing land flooded evaporator is not suitable for being used in the ship occasion.

Furthermore, the heat exchange tube bundle 3 and the end plate 1 are fixed by expansion or welding, the partition plate 4 is attached to the end plate 1 at one end and has no gap, a certain gap is reserved between the other end and the end plate 1, so that the refrigerant can flow from the upper area to the lower area, the partition plate 4 partitions the evaporation tube bundle, the first evaporation area 301 and the second evaporation area 302, the partition number is the same as the flow number of water, and the refrigerant and the water flow in the opposite direction.

The following reasons for the beneficial effects are specifically described:
the structure is compact: because the refrigerant does not have gas-liquid layering in the cylinder, the liquid refrigerant does not need to flow out from the liquid outlet after shaking, and therefore, the upper part of the cylinder does not need to reserve a space for storing the gaseous refrigerant, and the structure can also achieve a compact effect;
the oil return is convenient: the gaseous and liquid refrigerants flow in the cylinder together and carry the frozen oil, so that the frozen oil is prevented from being retained in the cylinder, and the oil return is ensured;
the refrigerant flushing amount is low: the refrigerant is in a gas-liquid mixed flowing state, and the density is lower, so that the flushing quantity of the refrigerant can be lower;
the heat exchange coefficient is high: the refrigerant in the gas-liquid mixing state is used for flushing the evaporation tube bundles back and forth under the action of the baffle plate, so that the heat exchange coefficient is high;
the degree of freedom of the structural arrangement is higher: the liquid inlet of the traditional flooded heat exchanger is required to be arranged at the bottom of the cylinder, so that the distance between the liquid inlet and the air outlet is increased, the problem of reliability caused by splashing of the liquid refrigerant out of the air outlet after shaking is avoided, and the refrigerant in the gas-liquid mixing state flows in the cylinder according to the flow, so that the necessity of arranging the liquid inlet at the bottom of the cylinder is avoided, and the degree of freedom of structural arrangement is higher.
