摘要： This application provides a heat exchange device and a heat exchange system. The heat exchange device has a first heat exchange mode, and includes a housing, a partition plate, an evaporator, and a compressor. The partition plate divides space inside the housing into an internal circulation cavity and an external circulation cavity. The evaporator and the compressor are located in the internal circulation cavity. A first valve group is disposed between an inlet of the compressor and an outlet of the evaporator. When the first heat exchange mode is used for heat exchange, the evaporator is communicated with the compressor by using the first valve group. In this application, the compressor is disposed in the internal circulation cavity, so that a temperature difference between the compressor and the evaporator is small, thereby reducing a slugging risk of the compressor.

摘要： Disclosed in the present application are an economizer and a refrigeration system comprising same. The economizer comprises: an outer shell that internally comprises a heat exchange cavity and a gas-liquid separation cavity; and a heat exchange tube bundle provided in the heat exchange cavity. The economizer is configured to enable refrigerants from a condenser to be subjected to heat exchange in the heat exchange cavity first, and then to be subjected to gas-liquid separation in the gas-liquid separation cavity after passing through a first-stage throttling device, such that gas refrigerants flow out of a gas outlet of the gas-liquid separation cavity, and liquid refrigerants flow out of a liquid outlet of the gas-liquid separation cavity. According to the economizer of the present application, the heat exchange cavity and the gas-liquid separation cavity are provided in the shell, the gas-liquid separation function of the economizer can be achieved, the heat exchange function of a subcooler can also be achieved, such that the structure of the two-stage compression refrigeration system with the function requirements of the subcooler can be more compact.

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.
