Airflow auxiliary heating device utilizing inclined plane in box body

Abstract

The invention discloses an airflow auxiliary heating device utilizing an inclined plane in a box body. The airflow auxiliary heating device comprises a main body, an auxiliary heating device and a heating device, the auxiliary heating devices are distributed around the inner wall of the main body and are arranged in the middle in the main body; a plurality of fixing columns are arranged in the main body and are used for fixing the heating device; two ends of the main body are respectively provided with a first ventilating duct and a second ventilating duct; the first ventilation pipeline and the second ventilation pipeline are communicated with the interior of the main body; an included angle of 30-60 degrees is formed between the contact surface of the bottom plate and the main body and the main body, so that good airflow uniformity is achieved, and the auxiliary heating device can achieve a good auxiliary heating effect; after entering the main body from the first ventilation pipeline, gas is in contact with the auxiliary heating device to be heated, and the heated gas enters the heating device to be further heated and is discharged out of the main body through the second ventilation pipeline; the flow rates of gas in all positions in the main body tend to be similar, so that the whole heating environment becomes uniform, and a better heating effect is achieved.

Description

technical field [0001] The invention relates to the technical field of heating, in particular to an airflow auxiliary heating device using an inclined surface inside a box body. Background technique [0002] When the air flow enters the pipe or box with a larger diameter from a pipe with a smaller diameter, a vortex will be generated at the inner wall of the joint. Heat exchange, thereby affecting the temperature distribution of the entire airflow; the usual solution is to increase the diameter of the airflow inlet pipe to reduce the cross-sectional gap between the pipe and the box, thereby reducing the generation of vortices, or changing the shape of the two to make the box The internal airflow tends to be gentle; but these methods will increase the cost of design and production, and may affect the function of the box. [0003] The simulation results of the internal heating box with a pipe diameter of 10 cm and a box section of a side length of 30 cm show that if a right a...
