The parts in the figures are numbered one by one and the corresponding numbers are given below. 1- Vacuum cleaner 2- Body 3- Dust collecting chamber (Dirt collecting Chamber) 4- Engine - Emis mouth (Suction inlet) 6- Air duct 7- Electronic card 8- Openness 9- Heat exchanger l 1- Gasket The vacuum cleaner (1), a body (2), a dust collector housed in the body (2) chamber (3), an engine (4) located in the body (2) and having a suction mouth (5), preferably located on the suction nozzle (5) and one end to the suction nozzle (5) and the other end to the powder contains an air duct (6) opening to the collecting chamber (3) (Figure 1).

In the vacuum cleaner (l), the air suction in the air duct (6) with the operation of the motor (4) it is pulled towards the mouth (5). Dust collection of one end of the air duct (6) vacuum effect in the dust collection chamber (3) by opening the chamber (3). is being created. The hose connected to the user dust collection chamber (3) (in the figures (not shown) performs the cleaning process with

The vacuum cleaner (1), which is the subject of the invention, is a device positioned on the air duct (6). electronic snow (7), at least one opening (8) located in the upper wall of the air duct (6), extending from the opening (8) into the air duct (6) depending on the electronic card (7). and a heat exchanger (9) that provides cooling of the electronic board (7). In the vacuum cleaner (l), which is the subject of the invention, the electronic card (7) is connected to the motor (4) suction nozzle. (5) is positioned on the air duct (6) where it is located. of the air duct (6) in the cooling of the electronic board (7) with the opening (8) on the upper wall the heat exchanger (9) used extends into the air duct (6). Engine (4) By rotating at high speeds, the air in the air duct (6) enters the suction port (5). attracts. Therefore, a high-speed air flow in the air duct (6) is formed. At the same time, the air drawn from the air duct (6) has not yet reached the engine (4). Since it does not pass through it, it is relatively colder. Electronic snow (7) The heat formed on it is transferred to the heat exchanger (9). Engine (4) cold air flow is provided in the air duct (6) and the heat exchanger Heat transfer takes place between the (9) surfaces and the air flow. surface the cooling heat exchanger (9), thus, more heat is transferred through the electronic card (7). and thus the electronic card (7) is cooled.
