Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in the figure, the utility model provides a hot-blast exchange device, it includes ventilation pipe 1, hot exchange pipe 2 and a plurality of cooling tube 3, hot exchange pipe 2 and cooling tube 3 all establish in ventilation pipe 1, hot exchange pipe 2 advance ventilation pipe 1 from ventilation pipe 1 lower extreme and hold out, the utility model has the advantages that hot exchange pipe 2 passes ventilation pipe 1, and cooling tube 3 establishes in ventilation pipe 1, and hot exchange pipe 2 expert has the heat, and cooling tube 3 is the heat equipartition in hot exchange pipe 2 on cooling tube 3, and ventilation pipe 1 is interior to lead to the air, and the air carries out the heat exchange with 3 surfaces of cooling tube and hot exchange pipe 2 surfaces, and heat exchange efficiency is high, and is effectual.

Hot oil flows in the heat exchange tube 2, so that the heat of the hot oil is large, and the heat exchange effect is good.

The flow direction of hot oil in the heat exchange tube 2 is consistent with the flow direction of air in the ventilation tube 1, and the heat exchange effect is good.

The cooling tube 3 between be parallel to each other, be convenient for carry out a lot of heat exchange between air and the cooling tube 3, heat exchange efficiency is high.

The radiating pipes 3 are distributed along the radial direction of the ventilating pipe 1, and the heat exchange between the air and the hot air on the surfaces of the radiating pipes 3 is more sufficient.

The radiating pipe 3 in built-in have liquid medicine, the radiating pipe 3 of being convenient for is the heat equipartition on radiating pipe 3.

The radiating pipe 3 is connected with the heat exchange pipe 2 through welding, so that the radiating pipe 3 is conveniently connected with the heat exchange pipe 2.

The both sides of 1 inner wall of ventilation pipe all be equipped with draw-in

groove

4, 3 both ends of cooling tube block respectively in draw-in groove 4, be convenient for fix in ventilation pipe 1 cooling tube 3.

Particularly, the utility model discloses a principle is that hot exchange pipe 2 passes ventilation pipe 1, and cooling tube 3 establishes in ventilation pipe 1, and hot exchange pipe 2 expert has the heat, and the heat equipartition in cooling tube 3 the hot exchange pipe 2 leads to the air on cooling tube 3 in the ventilation pipe 1, and the air carries out hot exchange pipe 2 with 3 surfaces of cooling tube and hot exchange pipe 2 surfaces, and heat exchange efficiency is high, and is effectual.

The working process is as follows: firstly, air is pumped into the ventilation pipe 1 by an air pump to move upwards, and hot oil in the heat exchange pipe 2 is pumped upwards through the ventilation pipe 1 by an oil pump; secondly, the heat of hot oil in the heat exchange tube 2 is uniformly distributed on the heat dissipation tube 3 by the heat dissipation tube 3, the air exchanges heat with the surface of the heat dissipation tube 3 and the heat in the heat exchange tube 2, and the air is changed into hot air to enter the next process.
