Description

Of course, the heating-cooling devices under which is made in the form of a plate with holes: through which the gaseous medium passes to heat or cool Luzdelin.

A disadvantage of the known devices is the measure of the heat treatment of the product and the low rate of heat exchange.

The previous device is distinguished from wear and tear by the fact that under it is made a type-setting of or more gas stoves: start-up:; holes in the form of В | I.khrevykh oscillators of acoustic oscillations.

Such an embodiment of the device permits an ibisbisiff heat exchange, improves the quality of heat treatment, and simplifies the technology: 13

The heating and cooling device consists of a working space / and a sub-floor of liqi1 and 2, in which combustion device 3 is installed. If it is necessary to supply a coolant (for example, air) into the working space, the latter is fed from an iodo-firebox through a nipple 4. and 6, and

Each of the chits is equipped with 7 holes (5) and 8, 9, and 10 (in plate 6) for the passage of coolant jets of jets of combustion products. The holes in the plate 5 are rectangular discontinuous slots, and the through holes in the plate 6 are made in the 15th view of the vortex generators of acoustic oscillations.

The cylindrical orifice 5 is a reaming chamber to which the inlet orifice 8 is tangentially adjacent and which is provided with an outlet; the first orifice 10.

The device works as follows.

Combustion products. the air iodine into the firebox through pipe 4 passes through the holes 7, 5, 9 and 10 b, and is fed under the treated pdedel / L to heat the product ii maintaining it) ia gas cushion. The gas that enters through the holes 7 and 5 into the resonating chamber, due to the tangential entry into the chamber, acquires a rotational motion. In the axial part of the resonating chamber and the outlet 10, a discharge zone is formed, and the jet flowing into the working space 1 from the region 10 is driven into an oscillatory motion. The system of vortex generators in the hearth provides rotation and tight oscillations of the jets incident on the metal. Thereby, the intrinsic turbulence of the gas jets and the protrusion increase; the path of the two gas flows along the surface of the gas stream increases, resulting in a heat exchange process between the jets and the metal; significantly 13Y | paV-niVaetsa those: sheratur "after about 1 on the surface of the product.
