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&#x2266;W/L&#x2266;0.75, wherein W is the width and L is the length.

Plate for heat exchanger

The present invention relates to a heat exchanger for carbon dioxide, in which a tank having a number of domes is coupled with a header and a connection member having a connection flow channel is interposed between the header and the tank, thereby easily changing a refrigerant flow channel, reducing the volume of a header tank, and improving productivity, pressure resistance and durability.

Heat exchanger

The present invention relates to a heat exchanger which can suitably regulate the quantity, the feeding position or the feeding order of heat exchange medium fed into tubes to adjust heat exchange performance according to cooling and heating load. The heat exchanger comprises a plurality of tubes placed at least one header, each tube having both ends fixed to the header, medium-distributing means installed at the header for feeding heat exchange medium to the specific tubes, a tank placed over the medium-distributing means, the tank having a medium-inlet pipe, a medium-outlet pipe and distribution passages for feeding heat exchange medium to specific regions of the medium-distributing means, and medium-regulating means installed at the tank and operated in response to a control signal for adjusting the feed of the heat exchange medium.

A heat exchanger tube and a heat exchanger that uses the heat exchanger tube. The heat exchanger tube is provided with a generally flat body has a plurality of refrigerant passages that pass through the interior of the flat body in the length direction thereof. The tube includes refrigerant passages which 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. A second curved portion is formed opposite to the first curved portion and is connected slowly to the first curved portion to thereby form a curve closed face. A pair of outside passages is disposed on the outermost both ends of the plurality of inside passages.

Heat exchanger tube and heat exchanger using the same

The gas-liquid separating condenser of the present invention can enhance the sub-cooling rate in the pre-sub-cooling section as well as in the total sections. Moreover, the present invention can have designs according to calculated conditional expressions of relative dimensional ratios of the sections in condensation of refrigerant to realize the optimum condensing efficiency regardless of the overall size of the gas-liquid separating condenser.

Multistage gas and liquid phase separation condenser

Disclosed is a thrust bearing structure for supporting a driving shaft for use in a variable displacement swash plate type compressor. The inventive thrust bearing structure supports a driving shaft of the compressor, and has a specific correlation between the inner and the outer diameters of a stationary race and a driving race, between the races and a cylinder bore and an outer diameter of the driving shaft. That is, a distance between an inner diameter of the stationary race and an outer diameter of the driving shaft is greater than a distance between an outer diameter of the stationary race and a surface of the center bore.
