[0003] With the progress of society, people have higher and higher requirements for chillers. Not only should the cooling effect be good, but also the size should be small and the floor space should be small. Therefore, in the process of research and development of chiller equipment, it is necessary to make reasonable use of the internal space of the chiller to further reduce the size of the chiller. The condensers used in current chillers are mostly cylindrical or rectangular, with thick thickness. The space occupied inside the chiller is large and concentrated, which is not conducive to reducing the size of the chiller.

[0007] A further improvement is that the vertical cross section of the condensation pipe is an ellipse which can reduce the thickness of the condenser assembly.
[0008] A further improvement is that the condenser tube is a copper tube, and a first silver coating for increasing the heat conduction effect is sprayed on the outer surface of the copper tube.
[0009] A further improvement is that the upper heat absorbing plate and the lower heat absorbing plate are aluminum plates, and the upper arc groove and the lower arc groove are respectively sprayed with a second silver coating and a third silver coating for increasing the thermal conductivity effect.
