Abstract
A plate heat exchanger includes a first plate having a first heat transfer region through which a first fluid flows, a first inlet into which the first fluid flows, and a first discharge portion through which the first fluid is discharged, and a second plate having a second heat transfer region through which a second fluid flows, a second inlet into which the second fluid flows, and a second discharge portion through which the second fluid is discharged, and stacked on the first plate. The first plate further includes a flat portion disposed to surround the first inlet portion, and the flat portion has an asymmetrical shape with respect to the first inlet.
Claims17
A plate heat exchanger comprising:
- a first plate including:
- a first heat transfer region configured to allow a first fluid to flow therethrough, the first heat transfer region having a groove;
- a first inlet configured to introduce the first fluid into the first heat transfer region;
- a first discharge portion configured to discharge the first fluid from the first heat transfer region;
- and
- a flat portion surrounding the first inlet, the flat portion having an asymmetrical shape with respect to the first inlet;
- and
- a second plate including:
- a second heat transfer region configured to allow a second fluid to flow therethrough;
- a second inlet configured to introduce the second fluid into the second heat transfer region;
- and
- a second discharge portion configured to discharge the second fluid from the second heat transfer region, the second plate being stacked on the first plate,
- wherein the flat portion includes:
- a first region located between a center of the first inlet and the groove;
- and
- a second region other than the first region,
- wherein the second region includes:
- a first boundary surface having a first end adjacent to a first end of the first plate and a second end connected to the groove;
- and
- a second boundary surface having a first end adjacent to the first end of the first plate,
- wherein a distance between the first boundary surface and the second boundary surface increases in a left-direction as the distance between the first boundary surface and the second boundary surface approaches from the first end of the first plate to the center of the first inlet,
- wherein a portion of the first boundary surface has a straight-line shape, and
- wherein a portion of the second boundary surface has a curved shape.
