Abstract:
The present invention relates to a heat exchanger plate, more particularly, in which a number of beads for imparting turbulence to refrigerant flowing through a channel of a plate are formed streamlined and guide beads arre formed in refrigerant distributing sections in order to reduce the pressure drop of refrigerant while realizing uniform refrigerant distribution. In the heat exchanger plate of a tube including a tank communicating with a channel, a number of first beads so arrayed in the plate that opposed sides are coupled to each other to impart turbulence to refrigerant flowing through the channel and refrigerant distributing sections provided in inlet and outlet sides of the channel and divided by at least one second bead to have a plurality of paths, the first beads are formed streamlined and satisfy an equation of 0.35 ≤ W/L ≤ 0.75, wherein W is the width and L is the length.
Abstract:
A motor driven compressor which can use refrigerant sucked into a swash plate chamber of the compressor to efficiently cool an electric motor, in which a motor unit (10) has an electric motor (13) installed in an inside motor room (12) for rotating a drive shaft (14) and a compressor unit (20, 120) is installed at one side of the motor unit (10). The compressor unit (20, 120) comprises: a front housing (30, 130) having at least a discharge chamber (31, 131) therein; a rear housing (60, 160) having a suction chamber (61, 161) and a discharge chamber (62, 162) formed therein, the suction chamber (61, 161) being partitioned from the discharge chamber (62, 162), and a refrigerant discharge port (64, 164) formed at one side communicating with the discharge chamber (62, 162); a cylinder block coupled between the front housing (30, 130) and the rear housing (60, 160) and having a plurality bores (41a and 42, 141 a and 142a) formed at both sides of the swash plate chamber (43, 143) and a refrigerant suction port (44, 144) formed at one side thereof; a swash plate (50, 150) placed in the swash plate chamber (43, 143) and coupled with the drive shaft (14) and a plurality of double head pistons (51, 151) for reciprocating within the bores (41a and 42, 141a and 142a) in cooperation with the rotation of the swash plate (50, 150); and feeding means (17, 45, 145) for feeding refrigerant from the swash plate chamber (43, 143) partially into the motor room (12) and partially into the suction chamber (61, 161) of the rear housing (60, 160).
Abstract:
Disclosed is a heat exchanger tube with a plurality of tumbling toy-shaped passages and a heat exchanger using the heat exchanger tube. The heat exchanger tube is provided with a generally flat body having predetermined values in length, height and width directions and with a plurality of refrigerant passages that are formed passed through the interior of the flat body in the length direction thereof, the tube including: the refrigerant passages are provided with a plurality of inside passages, each of which has a first curved portion that is made by changing a predetermined curve over at least a time or more to form a curve changing point protruding in the width direction of the body, by which turbulence activating parts are formed, and has a second curved portion that is formed opposite to the first curved portion and is connected slowly to the first curved portion to thereby form a curve closed face, and with a pair of outside passages disposed on the outermost both ends of the plurality of inside passages.
