Description

Refrigerant inlet and outlet header for evaporative condenser

Technical Field

The utility model relates to a refrigerant inlet and outlet header for an evaporative condenser, in particular to a refrigerant inlet and outlet header for an evaporative condenser, which can automatically correct deviation.

Background

The evaporative condenser is used as one of main heat exchange devices in the industries of refrigeration, chemical engineering and the like, and has a very wide application range. The evaporative condenser has the technical characteristics of water and electricity saving, and has a very wide market foundation. The heat exchange coil group is a core part in the evaporative condenser and has the functions of condensing and liquefying high-temperature and high-pressure refrigerant gas in the coil group and transferring the internal energy of the refrigerant gas to the water film on the outer surface of the heat exchange coil so as to raise the temperature of the water film on the outer surface of the coil and evaporate the water film. The evaporation of water absorbs heat, further reduces the temperature of water, thereby ensuring the condensation effect of the refrigerant in the heat exchange coil.

The refrigerant inlet and outlet collecting pipes in the heat exchange coil group play a role in connecting all heat exchange pipes and refrigerant inlet and outlet pipes, the structure of the heat exchange coil group ensures that the heat exchange pipes bear pressure resistance and are not deformed, all the heat exchange pipes are conveniently welded with the inlet and outlet collecting pipes, and the refrigerant entering from the refrigerant inlet and outlet pipes is uniformly distributed in the evaporation cold collecting pipe and is uniformly sent to all the heat exchange pipes.

The heat exchange coil pipe has the advantages of high heat exchange efficiency, high cleanliness in the pipe, pressure resistance and the like. The aluminum pipe has the advantages of high heat exchange efficiency, high cleanliness in the pipe, convenience in processing and the like, the aluminum pipe can ensure pressure resistance through the wall thickness with reasonable design, the aluminum refrigerant inlet and outlet header pipe is designed to be convenient to weld with the heat exchange coil pipe, the appearance design conforms to the design of a pressure container, and the compression deformation is small. The most desirable form of manifold is round, round pressure resistant. However, when the round header is butted with the heat exchange coil, the heat exchange coil needs to be chamfered so as to ensure that the coil does not enter too much in the header, and thus the air flow distribution of the header is not uniform.

The heat exchange tube is a phi 25 aluminum tube, the center distance between the tubes is 50mm, namely, if the heat exchange tube is welded on the outer side of the header, the welding space is only 25mm in clearance, and the welding difficulty is high.
