A heat exchanger includes a shell, refrigerant distributor, tube bundle, and a first baffle. The shell has a refrigerant inlet through which at least refrigerant with liquid refrigerant flows and a shell refrigerant vapor outlet. A longitudinal center axis of the shell extends substantially parallel to a horizontal plane. The refrigerant distributor fluidly communicates with the refrigerant inlet and is disposed within the shell. The refrigerant distributor has at least one liquid refrigerant distribution opening that distributes liquid refrigerant. The tube bundle is disposed inside of the shell below the refrigerant distributor. The first baffle extends from a first lateral side of the shell. The first baffle is vertically disposed 5% to 40% of an overall height of the shell above a bottom edge of the shell, and extends laterally inwardly from the first lateral side by a distance not more than 20% of a width of the shell.

Heat exchanger

A heat exchanger includes a shell, a refrigerant distributor, tube bundle, and first baffle. The shell has a refrigerant inlet through which at least refrigerant with liquid refrigerant flows and a shell refrigerant vapor outlet. A longitudinal center axis of the shell extends substantially parallel to a horizontal plane. The refrigerant distributor fluidly communicates with the refrigerant inlet and is disposed within the shell. The refrigerant distributor has at least one liquid refrigerant distribution opening that distributes liquid refrigerant. The tube bundle is disposed inside of the shell below the refrigerant distributor. The first baffle extends downwardly from the refrigerant distributor at a top of the tube bundle to at least partially vertically overlap the top of the tube bundle. The first baffle is disposed laterally outwardly of the tube bundle toward a first lateral side of the shell.

A heat exchanger includes a shell, refrigerant distributor, tube bundle, and first upper baffle. The shell has a refrigerant inlet through which at least refrigerant with liquid refrigerant flows and a shell refrigerant vapor outlet. A longitudinal center axis of the shell extends substantially parallel to a horizontal plane. The refrigerant distributor fluidly communicates with the refrigerant inlet and is disposed within the shell. The refrigerant distributor has at least one liquid refrigerant distribution opening that distributes liquid refrigerant. The tube bundle is disposed inside of the shell below the refrigerant distributor so that the liquid refrigerant discharged from the refrigerant distributor is supplied to the tube bundle. The first upper baffle is vertically disposed at a top of the tube bundle. The first upper baffle extends laterally outwardly from the tube bundle toward a first lateral side of the shell.

A condenser for a vapor compression system includes a shell and a tube bundle. The shell has a refrigerant inlet and a refrigerant outlet. The tube bundle includes a plurality of heat transfer tubes disposed inside the shell. Refrigerant discharged from the refrigerant inlet is supplied onto the tube bundle. The heat transfer tubes extend generally parallel to the longitudinal center axis of the shell. The heat transfer tubes are arranged to form a first vapor passage extending generally vertically along a first passage lengthwise direction through at least some of the heat transfer tubes. The first vapor passage has a first minimum width measured perpendicularly relative to the first passage lengthwise direction and the longitudinal axis. The first minimum width is larger than a tube diameter of the heat transfer tubes, and the first minimum width is smaller than four times the tube diameter.

Condenser

A condenser for a vapor compression system includes a shell, a tube bundle, and a tube support structure. The shell has a refrigerant inlet and a refrigerant outlet. The tube bundle includes a plurality of heat transfer tubes disposed inside the shell. Refrigerant discharged from the refrigerant inlet is supplied onto the tube bundle. The heat transfer tubes extend generally parallel to the longitudinal center axis of the shell. The tube support structure is configured and arranged to support the plurality of heat transfer tubes in the tube bundle within the shell. The tube support structure includes at least one tube support plate inclined relative to a vertical direction perpendicular to the longitudinal center axis of the shell.

Condenser with tube support structure

A heat exchanger includes a shell, a refrigerant distributor disposed in the shell, and a heat transferring unit disposed in the shell. The shell has a refrigerant inlet through which at least liquid refrigerant flows and a shell refrigerant vapor outlet. The refrigerant distributor includes a first portion and a second portion. The first portion is connected to the refrigerant inlet to receive refrigerant from the inlet. The first portion has at least one first refrigerant liquid distribution opening and a first refrigerant vapor distribution outlet opening. The second portion is connected to the first portion to receive refrigerant from the first refrigerant liquid distribution opening. The second portion has at least one second refrigerant liquid distribution opening and at least one second refrigerant vapor distribution outlet opening. The heat transferring unit is disposed below the refrigerant distributor to receive liquid refrigerant discharged from the second portion of refrigerant distributor.
