Condenser

A condenser, comprising:

• a condensing tube including a refrigerant inlet formed at one end thereof, a refrigerant outlet formed at another end thereof, and a passage pipe having a heat radiation protrusion formed on an outer circumference thereof, the heat radiation protrusion comprising a plurality of heat radiation protrusions protruded in a serration shape where a triangle protrusion is attached on the outer circumference of the cooling tube;
• and
• a cooling plate having a groove on which the condensing tube is mounted so as to prevent a separation of the condensing tube, and a plurality of bent pieces formed protruding from left and right sides of the groove;
• wherein the plurality of heat radiation protrusions are not formed on a part of the outer circumference of the condensing tube mounted on the groove that face-contacts the cooling plate.

A condenser, comprising:

• a condensing tube including a refrigerant inlet formed at one end thereof, a refrigerant outlet formed at another end thereof, and a passage pipe having a heat radiation protrusion formed on an outer circumference thereof, the heat radiation protrusion comprising a plurality of heat radiation wings each having an apex portion and a space defined between the apex portions;
• and
• a cooling plate having a groove on which the condensing tube is mounted so as to prevent a separation of the condensing tube, and a plurality of bent pieces formed protruding from left and right sides of the groove;
• wherein the plurality of heat radiation wings are not formed on a part of the outer circumference of the condensing tube mounted on the groove that face-contacts the cooling plate.

A condenser comprising:

• a condensing tube constructed from a passage pipe having a refrigerant inlet formed at one end thereof and a refrigerant outlet formed at another end thereof, the condensing tube comprising a plurality of heat radiation protrusions formed on an outer circumference thereof;
• and
• a cooling plate having a groove on which the condensing tube is mounted so as to prevent a separation of the condensing tube, and a plurality of bent pieces formed protruding from left and right sides of the groove, the cooling plate being bent in a multi-layer structure of a three dimension to increase an area ratio per unit volume;
• wherein the plurality of heat radiation protrusions are not formed on a part of the outer circumference of the condensing tube mounted on the groove that face-contacts the cooling plate.
