Abstract: A heat exchanger including a first heat absorbing section and a second heat releasing section, such that a plurality of heat exchange structures are arranged, preferably in parallel, in a plane of extension. The first heat absorbing section includes a first plurality of fluid guiding devices and the second heat releasing section comprises a second plurality of fluid guiding devices. Each heat exchange structure includes at least one fluid guiding devices of the first plurality and at least one fluid guiding devices of the second plurality thermally connected to each other, and preferably arranged in parallel. A clearance disposed between two adjacent heat exchange structures allows airflow between adjacent heat exchange structures and/or each heat exchange structure includes a heat sink to thermally couple the fluid guiding devices of the first plurality and the fluid guiding devices of the second plurality.

Abstract: In order to reduce the dimensions and costs of a heat exchanger, while at the same time increasing its heat effectiveness, it is suggested to configure the heat exchanger such that a condenser side and an evaporator side of the heat exchanger are separated from each other by a barrier.

Abstract: A cooling system, in particular for electronics cabinets, is proposed, comprising a casing, wherein the casing comprises at least a cabinet side partitionment, wherein the cooling system comprises a first cooling circuit and a second cooling circuit, wherein the second cooling circuit is an active cooling circuit, wherein the first cooling circuit and the second cooling circuit are thermally coupled, wherein the second cooling circuit is not disposed in the cabinet side partitionment.

Abstract: A cooling system, in particular for electronics cabinets, comprising a casing, wherein the cooling system comprises a first cooling circuit and a second cooling circuit, the first cooling circuit comprising a heat releasing section and the second cooling circuit comprising a heat releasing section, is provided, wherein the casing comprises at least three compartments including a cabinet side compartment, a first external side compartment and a second external side compartment, wherein the three compartments are fluidically separated from each other so that respective airflows in the cabinet side compartment, the first external side compartment and the second external side compartment do not mix, wherein the heat releasing section of the first cooling circuit is arranged in the first external side compartment and wherein the heat releasing section of the second cooling circuit is arranged in the second external side compartment.

Abstract: In order to reduce the dimensions of a heat exchanger it is suggested to configure the heat exchanger in such a way that it has a heat exchanging element comprising a condenser unit and an evaporator unit. The evaporator unit comprises a lower end area, an upper end area and a plurality of channels for transporting a refrigerant from the lower end area to the upper end area, said refrigerant comprising liquid and gas. The upper end area is connected to the lower end area by a first line which is configured to transfer only liquid from the upper end area to the lower end area.

Abstract: A portable automobile alarm hung over the top of an automobile side window is secured in place by raising the window into its frame. The portion of the unit positioned on the interior side of the glass contains a sensor, a receiver, and associated electronic circuitry. The exterior unit houses an alarm siren. The unit is powered from an internal battery or from a cigarette lighter. The unit may be armed and disarmed by a remote transmitter.
