Abstract:
The present invention relates to a heat exchanger tube, in which turbulence generating portions placed within a passage of the tube are rounded into curved configurations with predetermined curvatures so that they are hardly damaged or fractured during extrusion to improve machinability and product quality, in which upper and lower circular passages formed in upper and lower sides of a tube body are connected via a connecting passage having the turbulence generating portions so that more passages having a smaller hydraulic diameter can be formed in the tube of the same size without unnecessary waste of tube material, and in which the turbulence generating portions are arranged in a lateral direction (Z-axial direction) of the tube body so that the passage is not filled with condensate films even though a large quantity of condensate is produced to reduce the thickness of the condensate films or break the condensate films to promote refrigerant to be converted into turbulent flow, thereby improving heat transfer ability.

Abstract:
A swash plate type compressor includes a drive shaft rotated by a driving source, a swash plate fixedly installed at the drive shaft, a piston reciprocated by the swash plate, a cylinder bore, where the piston is installed to be capable of sliding, for guiding reciprocation of the piston, a thrust bearing supporting a thrust force generated the swash plate and the drive shaft, a race having a protrusion for preventing rotation radially formed at an outer circumference thereof, and a cylinder block having a protrusion fixing means for preventing rotation of the race by fixing the protrusion of the race. Thus, abrasion due to rotational friction between the flat surface of the race and the thrust surface of the cylinder block can be prevented. Also, since generation of a gap between the cylinder block and the swash plate because of the abrasion of the flat surface of the race and the thrust surface of the cylinder block can be prevented, noise in the compressor, damage to the thrust in bearing, and damage to the neighboring member can be prevented. Further, when incorrect assembly is performed, the protrusions interfere with the piston so that incorrect assembly can be easily found and assembly can be easily performed.
