The following specification particularly describes the application and the manner in which it is to be performed.

PRIORITY STATEMENT
The present application hereby claims priority from Indian patent application with the application number 202341024924, filed on 31 March 2023, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD OF INVENTION
The present invention relates to cooling and ventilation devices. More particularly, it relates to a novel forced air-cooling device for metallurgical applications, which can be used for cooling workpieces instantaneously after heat treatment.

BACKGROUND OF INVENTION
In metallurgical industry, various types of workpieces are developed and heat-treated. On many occasions, there is a requirement to cool the workpiece instantly, which is achieved by employing an external cooling source. Conventionally, water quenching or oil quenching is employed to cool the workpiece. However, these methods have some limitations, such as uneven cooling, thermal shock, and corrosion of the workpiece. Therefore, there is a need for a novel forced air cooling device that can provide an even and controlled cooling of the workpiece without causing any damage.
To address the existing problem, a novel forced air-cooling device has been developed. This device is designed to provide rapid and uniform cooling of work pieces by directing a high velocity stream of air onto the surface of the work.

OBJECT OF THE INVENTION
The object of the present invention to design a novel forced air-cooling device which offers a rapid and uniform cooling of work pieces by directing a high velocity stream of air onto the surface of the work.
SUMMARY OF THE INVENTION
This summary is provided to introduce a selection of concepts, in a simplified format, that are further described in the detailed description of the disclosure. This summary is neither intended to identify key or essential inventive concepts of the disclosure nor is it intended for determining the scope of the disclosure.

The present invention discloses a forced air-cooling device for metallurgical applications, comprising a blower unit comprising a motor and a fan for generating a high-velocity air stream; a cooling chamber with nozzles for directing the high-velocity air stream towards a workpiece; and a control unit for monitoring and adjusting temperature and pressure parameters.

DESCRIPTION OF THE INVENTION
The present invention relates to a novel forced air-cooling device for metallurgical applications, which can be used for cooling workpieces instantaneously after heat treatment. The device comprises a blower unit and a control unit.
The blower unit includes a motor and a fan, which generates a high-velocity air stream.
In accordance with an embodiment of the present invention, the blower unit is designed to generate a high-velocity air stream, which is directed towards the workpiece through the nozzles in the cooling chamber.
The blower unit is designed to generate a high-velocity air stream, which is directed towards the workpiece through the nozzles in the cooling chamber. The cooling unit is designed to cool the air stream by circulating the coolant through the heat exchanger. The coolant absorbs heat from the air stream and is circulated back to the cooling unit, where it is cooled by the refrigeration system. The coolant pump is used to circulate the coolant through the heat exchanger and the cooling unit.
The control unit is designed to monitor the temperature and pressure of the coolant and adjust the speed of the motor and the flow rate of the coolant to maintain a constant temperature and pressure of the coolant. The temperature and pressure sensors are connected to the controller, which receives the feedback and adjusts the speed of the motor and the flow rate of the coolant accordingly.

ADVANTAGES AND APPLICATION
The present invention has several advantages over the conventional cooling methods. It provides an even and controlled cooling of the workpiece without causing any damage. It eliminates the need for water or oil quenching, which reduces the risk of corrosion and thermal shock. It also reduces the overall cooling time and increases the productivity of the metallurgical process.
