Thermoelectric air-cooling unit

The inventive thermoelectric air-cooling unit comprises thermomodules (a device based on the Peltier effect) whose active surfaces are connected to an absorption element and a transmission element. Said thermomodules are arranged on a plate in such a way that a thermobattery is formed. In order to transmit heat from the absorption element to the transmission element during operation, a constant voltage is supplied to the thermobattery. The result of said process is in that the absorption element, which is supposed to be arranged in an insulated chamber, is cooled and the transmission element is heated. The heat is removed from the transmission element by means of a ribbed radiator and a ventilator. The absorption element is also provided with a ribbed radiator and a ventilator. The inventive thermoelectric air cooling unit is provided with an insulation against loss of heat, a control block and a device for compensating changes of geometrical dimensions of the thermomodules and surrounding construction elements of the unit. Said thermoelectric air-cooling unit is characterised in that it is provided with the following novel construction elements, i.e. means for arranging the thermomodules in such a way that the thermobattery is formed and a device for compensating changes of geometrical dimensions of the construction elements of the unit.
