Abstract:
The invention relates to a cooling system comprising an essentially flat evaporator consisting of individual evaporation plates (3a). 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.
Abstract:
The invention relates to a storage device 1, particularly a cooling and freezing device for blood products, and a method for monitoring a temperature-controlled storage device 1. The temperature-controlled storage device 1 has at least one working capacity 23, the temperature of which is controllable by at least one temperature control unit 25. At least one temperature sensor 26a-26e is assigned to the working capacity 23, and this sensor is coupled to a temperature monitoring controller. The temperature monitoring controller is able to be coupled at least intermittently with an analysis point via a preferably packet-based data communication system for the purpose of transmitting temperature measurement values.
