Abstract: The invention relates to an apparatus for cooling a heat source of a motor vehicle, comprising a hollow heat sink, an inlet for introducing a cooling fluid, an outlet for discharging a cooling fluid, a first collecting region for collecting the introduced cooling fluid, a second collecting region for collecting the cooling fluid to be discharged, and an insert part for guiding the cooling fluid from the first to the second collecting region, wherein the first and second collecting regions and the insert part are arranged within the heat sink.

Abstract: The invention relates to an apparatus and process for controlling automatic baking in a retail store In on embodiment, the baking apparatus includes an oven, an infeed device for feeding in dough slabs and a transport mechanism for transporting the dough slabs from the infeed device through the interior of the oven to a delivery station at which the ready-baked goods are made available to customers. Further, the apparatus includes a data processing unit that: records the quantity of baked goods made available, receives by way of a data network from the retail store's point-of-sale system the number of baked goods sold, and prompts the baking apparatus to start up the baking process on the basis of a comparison of those two values. In one aspect, the present invention provides for control of the level for the delivery station together with devices present in the retail store.

Abstract: The invention relates to a baking apparatus including an oven, a heating device, and a transport device for the transport of dough slabs through the interior of the oven. The heating device and the transport device are fed with an operating current. Further, the apparatus includes at least one monitoring device for monitoring the operating current of at least one of the two devices, and which increases the operational reliability of the baking apparatus. The monitoring device has at least one interface for outputting of a monitoring signal.

Abstract: A heat exchanger (1) with at least one heat-exchange tube (11) which is held at the end in an end piece (3) such that the joint is liquid- and gas-tight. The end piece (3) has an opening for each tube to which it is connected, allowing the heat-exchange fluid to pass through from the tube (11) into a conduit box and in the opposite direction, a sleeve-like connection socket (8) being located in the region of each opening. The connection socket (8) comprises a cylindrical slot (9) coaxial to the opening and open at the heat-exchange tube end, forming an inner (14) and outer (15) annular wall. The end of the heat-exchange tube (11) is pushed into the slot. A section of the outer annular wall (15) adjacent to the heat-exchange block is longer than the corresponding section of the inner annular wall (14).
