| 摘要 |
The invention relates to a cooling system comprising an essentially flat evaporator consisting of individual evaporation plates ( 3 a). Each evaporation plate comprises two high-grade steel plates ( 9 and 10 ) of different thicknesses, that are assembled by means of welding points ( 6 ) and welding seams ( 8 ). A channel ( 14 ) is formed between the high-grade steel plates ( 9 and 10 ), through which a coolant flows. Preferably, the evaporator forms part of the inner housing of a refrigerating appliance. The evaporator is produced by welding the plates ( 9 and 10 ) together. Compressed air is then blown between the plates ( 9 and 10 ), whereby the thinner of the two plates ( 9,10 ) is curved in such a way the channel ( 14 ) is created for the coolant.
