Piece type heat exchange silencer

Abstract

The invention discloses a piece type heat exchange silencer which satisfies a plurality of technical indexes such as a noise eliminating coefficient, the heat exchange efficiency, regenerative noise, resistance loss and the like. According to the piece type heat exchange silencer, space wasting is reduced on the condition that all indexes are satisfied; the noise eliminating coefficient is maintained, the regenerative noise, and the flow resistance are increased due to the fact that a heat exchange pipe bundle is arranged inside noise eliminating materials; purposes of waste heat recovery or air conditioning treatment are achieved and extra space is not occupied during the heat exchange process; heat dissipation loss is reduced due to the fact that peripheral noise eliminating materials are made of thermal insulation type materials; the heat exchange effect is increased due to the fact that the middle noise eliminating materials are made of ordinary noise eliminating materials.

Description

technical field [0001] The invention is a device with both heat exchange performance and noise reduction performance, and more specifically relates to a sheet muffler with heat exchange function mainly used in the field of HVAC. Background technique [0002] In the field of HVAC, there are generally two types of treatment for air, namely heat and humidity treatment and noise reduction. Heat and moisture treatment is generally heated or cooled to the desired treatment state by surface heat exchangers. Noise reduction and noise reduction are generally achieved through a sheet muffler. Chip mufflers and surface heat exchangers can generally be installed on air ducts, civil air ducts or air conditioning units. Generally speaking, the minimum effective length of the plate muffler is 1.0m, and the installation space of the surface heat exchanger also needs to be about 1.0m. Obviously, the two are installed separately, resulting in a waste of space. The reason for this waste of...

Obviously, the two are installed separately, resulting in a waste of space

The reason for this waste of space is that the muffler has a single function and cannot have the heat exchange function at the same time.

[0003] In the utilization of waste heat from automobile exhaust, a kind of resistant muffler that can exchange heat has been proposed in the literature, but because there are no fins installed in the heat exchange tube bundle, the heat exchange area is too small, resulting in low heat exchange efficiency. Cannot be applied to the field of low temperature differential heat transfer

In the field of industrial power, a kind of small-hole muffler that can exchange heat has been proposed in the literature, but the heat exchange tube bundle is directly installed on the air flow channel, which affects the area of ​​the air flow channel, resulting in increased air regeneration noise and noise reduction. Unfavorable conditions such as reduced coefficient and increased flow resistance

At the same time, since the existing muffler with heat exchange and energy supply is not insulated, the heat exchange loss increases
