摘要： The present application provides a falling film evaporator. The falling film evaporator comprises a housing, a gas outlet, a cover, a gas flow channel, and a plurality of flow guide members. The housing has a length direction and a height direction, and the housing defines an accommodating cavity. The gas outlet is provided at the upper portion of the accommodating cavity. The cover is provided in the accommodating cavity and defines a cover accommodating cavity, the cover accommodating cavity has a lower cover opening located below, and the cover accommodating cavity is configured to accommodate at least one part of a heat exchange tube bundle. The gas flow channel is located between the housing and the cover and enables the lower cover opening of the cover accommodating cavity to be in communication with the gas outlet. The plurality of flow guide members are arranged in the gas flow channel along the height direction of the housing. Here, in the height direction of the housing, one of two adjacent flow guide members is connected to the housing and is separated from the cover by a certain distance, and the other of the two adjacent flow guide members is connected to the cover and is separated from the housing by a certain distance. The falling film evaporator in the present application has the advantage of being high in gas-liquid separation efficiency, and the machining process of the flow guide members of the falling film evaporator is simple.

摘要： The present application provides an evaporator, comprising: a housing; and a falling film tube bundle disposed in an accommodating cavity and arranged in columns, the falling film tube bundle comprising a plurality of heat exchange tubes, the centers of the heat exchange tubes in each column being arranged along a height direction, and the centers of two adjacent heat exchange tubes in adjacent columns being staggered in a width direction of the accommodating cavity; wherein the falling film tube bundle is configured in a way that among four adjacent heat exchange tubes in two adjacent columns, a minimum distance between outer surfaces of at least two heat exchange tubes in different columns is greater than a minimum distance between outer surfaces of two heat exchange tubes in the same column. In the present application, a flow rate of gas flowing among the corresponding heat exchange tubes is reduced by increasing the flow space of a refrigerant in the width direction W, so that a ratio of the gas phase Reynolds number Rev to the liquid film Reynolds number Refilm is reduced, and thus the heat exchange efficiency of the evaporator is improved.
