Abstract

The invention relates to a heat exchanger. The heat exchanger comprises a shell and a heat exchange tube bundle located in the shell, the shell is provided with an inlet and an outlet, a refrigerant flows in through the inlet, exchanges heat with fluid in the heat exchange tube bundle and then flows out of the outlet, the outlet is provided with an extending section extending into the shell, and the extending section is provided with an accommodating part used for accommodating at least one part of liquid in the refrigerant flowing to the outlet after heat exchange. The heat exchanger has the advantages that the heat exchanger is easy to manufacture, mount and maintain; the cost is low; and by conducting structural optimization design on the outlet pipeline of the heat exchanger, the influence of suction with liquid can be effectively controlled, and the overall performance, safety and reliability of the system are enhanced.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat exchanger. Background technique [0002] The prior art provides various types of heat exchange devices, equipment or systems, which have been widely used in many industries and places, and can bring great convenience. However, these existing heat exchange devices, equipment or systems still have some disadvantages and deficiencies in aspects such as structural configuration, heat exchange effect, work performance, manufacture, installation and maintenance, etc., which can be further improved and optimized. [0003] For example, in figure 1 shows a side view structure of an existing flooded evaporator. The shells of this type of flooded evaporator are mostly cylindrical and have a large space volume, and the heat exchange tube bundles are installed in the shell At the bottom of the body, the refrigerant flows in from the inlet A of the shell, and leaves the flooded ...
