Embodiment Construction

[0029] The advantages of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0030] combine Figure 1 to Figure 6 , is a schematic structural view of the combination of the inner lining 120 and the outer jacket 110 of the air amplifier 100 of the present invention. In the present invention, the air amplifier 100 includes a casing 110 and an inner liner 120 , and the inner liner 120 is inserted into the outer casing 110 to form the air amplifier 100 . In order to provide external compressed air to the air amplifier 100, the overcoat 110 is provided with a through hole 111, the through hole 111 communicates with the external compressed air source and the inside of the overcoat 110, corresponding to the through hole 111, the inner lining opposite the air outlet end inside the overcoat 110 The part of 120 is folded, that is, part of the liner 120 is folded inward to form a structure similar to a bell mou...

Abstract

The invention provides an air amplifier capable of increasing air flow amount. The air amplifier comprises an outer sleeve, and a lining inserted into the outer sleeve; the outer sleeve is provided with a through hole; a part of the lining corresponding to the though hole shapes like a trumpet, so that a sealed space is formed between the outer sleeve and the lining, and the sealed space is communicated with the though hole, and is used for accommodating outer compressed air; a gap communicated with the sealed space is arranged between an air inlet end of the lining and the outer sleeve, and the gap is communicated with an air channel in the lining; the inner wall of the air inlet end shapes likes a round corner, so that coanda effects of air flows through the through hole, the sealed space, and the gap are induced. The air amplifier is capable of increasing air discharging speed, and realizing real-time adjustment based on working conditions.

Description

technical field [0001] The invention relates to the field of cooling devices, in particular to an air amplifier capable of increasing air flow. Background technique [0002] In the prior art, the strengthening mechanism of aluminum extrusion profiles is mainly on-line quenching, and the general production process is: extrusion-quenching-cutting-straightening-sawing-framing-aging. The effect of quenching directly affects the mechanical properties of the profile. The temperature drop rate of the profile in the quenching section is proportional to the properties of the profile. In the quenching section, the existing general methods are fan cooling and water cooling. The fan cooling is provided by the fan at the profile outlet to cool the high-temperature profiles. [0003] The existing online air-cooling system of the extrusion machine adopts the air blowing method of the fan, and the wind force is scattered and not concentrated, and the wind force intensity is not enough. Th...
