Abstract

A cold appliance comprising a cooling module ( 102 ) and a cabinet ( 101 ) comprising a cold compartment ( 104 ). The cooling module comprises an air outlet ( 43 ) delivering cooled air to the cold compartment and an air inlet ( 44 ) receiving air from the cold compartment. The cooling module is arranged at the bottom of the cold appliance, and comprises a cold section ( 34 ), and a warm section ( 35 ), which is separated from the cold section by an insulating wall ( 105 ). An evaporator ( 33 ) is arranged in the cold section, and a compressor ( 36 ) and a condenser ( 32 ) is arranged in the warm section. The condenser comprises a condenser tube ( 32 ), which is arranged in windings on or integrated in a bottom plate ( 31 ) of the cooling module.

wherein the cooling module further comprises an inlet opening ( 38 ), an outlet opening ( 41 ), a partition wall ( 40 ), and a fan ( 37 ) configured to draw air through the inlet opening ( 38 ) and over the bottom plate ( 31 ) and expel the air out of the outlet opening ( 41 ), wherein the partition wall ( 40 ) is arranged such that air passing from the inlet opening ( 38 ) to the outlet opening ( 41 ) travels from the inlet opening ( 38 ) in a first direction, around the partition wall ( 40 ), and then toward the outlet opening ( 41 ) in a second direction that is opposite the first direction, and
wherein the cooling module further comprises at least one curved fin arranged to guide air passing from the inlet opening ( 38 ) to the outlet opening ( 41 ) around the partition wall ( 40 ).

2. The cold appliance according to claim 1 , wherein the cooling module ( 102 ) comprises a drain water tray ( 46 ), which is arranged adjacent to the condenser tube ( 32 ), for receiving defrost water from the evaporator ( 33 ).

3. The appliance according to claim 2 , wherein the drain water tray ( 46 ) is constituted by a portion of the bottom plate ( 31 ).

4. The cold appliance according to claim 2 , wherein the drain water tray ( 46 ) is constituted by a separate tray mounted to be in direct contact with the top of the condenser tube ( 32 ).

5. The cold appliance according to claim 2 , wherein the condenser tube ( 32 ) is arranged inside the drain water tray ( 46 ).

6. The cold appliance according to claim 2 , wherein the cooling module ( 102 ) further comprises a defrost water collecting device ( 48 ) arranged below the evaporator ( 33 ), and a draining pipe ( 49 ) extending from the defrost water collecting plate to the drain water tray ( 46 ), and guiding the defrost water to the drain water tray.

7. The cold appliance according to claim 6 , wherein the defrost water collecting device ( 48 ) comprises a plate or a tray on or in which the evaporator ( 33 ) is arranged.

8. The cold appliance according to claim 1 , wherein the cabinet ( 101 ) comprises two side wall panels ( 1 ) and a rear wall panel ( 4 ), and wherein at least one of the side wall panels, preferably the side wall panel which partly encloses the cold section ( 34 ) of the cooling module ( 102 ), is attached to the bottom plate ( 31 ).

9. The cold appliance according to claim 8 , wherein at least one of the side wall panels ( 1 ) or the rear wall panel ( 4 ) comprises a pre-foamed panel, preferably made in a continuous double belt foaming process.

10. The cold appliance according to claim 1 , wherein the bottom plate ( 31 ) comprises a support means, such as feet and/or wheels, and preferably also leveling means.

11. The cold appliance according to claim 1 , wherein a condensation preventing device ( 160 ) comprising a heat carrier tube ( 28 , 160 ) is arranged in thermal contact with the condenser tube ( 32 ).

12. The cold appliance according to claim 1 , wherein the bottom plate ( 31 ) comprises fastening means to securely fasten the compressor, and fastening means to securely fasten a fan and part of a door hinge.

13. A cold appliance comprising a cooling module ( 102 ), and a cabinet ( 101 ), which comprises a cold compartment ( 104 ), wherein the cooling module comprises an air outlet ( 43 ) delivering cooled air to the cold compartment, and an air inlet ( 44 ) receiving air from the cold compartment, wherein the cooling module is arranged at the bottom of the cold appliance, and wherein the cooling module comprises a cold section ( 34 ), a warm section ( 35 ), which is separated from the cold section by an insulating wall ( 105 ), an evaporator ( 33 ) arranged in the cold section, and a compressor ( 36 ) and a condenser ( 32 ) arranged in the warm section, characterized in that the condenser comprises a condenser tube ( 32 ) including condenser tube windings integrated into a bottom plate ( 31 ) of the cooling module that extend horizontally, wherein the direct contact or integration between the windings and the bottom plate facilitates heat transfer between the windings and the bottom plate,
wherein the cooling module further comprises an inlet opening ( 38 ), an outlet opening ( 41 ), a partition wall ( 40 ), and a fan ( 37 ) configured to draw air through the inlet opening ( 38 ) and over the bottom plate ( 31 ) and expel the air out of the outlet opening ( 41 ), wherein the partition wall ( 40 ) is arranged such that air passing from the inlet opening ( 38 ) to the outlet opening ( 41 ) travels from the inlet opening ( 38 ) in a first direction, around the partition wall ( 40 ), and then toward the outlet opening ( 41 ) in a second direction that is opposite the first direction, and
