The invention relates to devices for cooling electric apparatuses filled with dielectric liquid, preferably for cooling oil transformers.

A conventional device for cooling electrical apparatus, containing a container filled with dielectric fluid, its outlet nozzle, radiator and radiator outlet nozzle. The upper part of the tank is connected by means of pipes to the lower part of the radiator, a. the upper part of the radiator - with the lower part of the capacity fl.

The drawbacks of the cooling device are the need to remove the device from the electrical apparatus, to locate the bent pipes, and therefore increase vibration, the need for additional attachment of the device to the electrical apparatus, as now mounting with the help of nozzles is not enough, and the inability to use the blast cooling system ( since there is no bracket for securing engines to blow) and an increase in labor intensity, consumption of materials and dimensions of the apparatus.

A device for cooling oil-filled transformers is known, which contains a system of tubular radiators connected to manifolds, which are connected to a transformer tank by means of nozzles, and a diffuser nozzle 2J is installed on the inlet nozzle of each of the radiators inside the tank.

However, the known device does not provide effective cooling ....

The aim of the invention is to increase the cooling efficiency.

This goal is achieved by the fact that in a device for cooling electric apparatuses containing a system of tubular radiators with headers that are connected to a tank of an electrical apparatus by means of nozzles, plates are installed in the cavity of the upper and lower collectors adjacent to the nozzle and part of the pipes. with nalon, and the plates in the upper and lower collectors are tilted in opposite directions.

FIG. 1 shows the proposed device for cooling electric apparatuses, the general view of FIG. 2 is a section A-A in FIG. 1, FIG. 3-- section BB in FIG. 1, in FIG. 4 is a diagram of the movement of a dielectric fluid.

The device for cooling the electrical apparatus contains a system of tubular radiators 1, connected to the collectors 2, which by means of nozzles 3 are connected to the tank 4 of the electric apparatus, in the cavity of the upper and lower collectors 2 adjacent to the nozzle, 3 and part of the pipes 1, plastids are installed 5 and b C inclined, with the plates in the upper and lower collector .pax. inclined in opposite directions.

; The cooling device operates as follows. The heated dielectric liquid from the upper part of the tank enters through the pipe 3 into the collector 2 (Fig 2) and through part of the pipes 1 fenced off by the plate 5 is lowered into the lower collector 2, then rises through the main part of the pipes into the upper collector 2 and again goes down pipes, fenced off the second plate 6, and then through the pipe in the lower manifold enters the bottom of the tank.

The use of the invention provides an efficient cooling of electrical apparatus.
