Abstract
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.
