Silencing and noise-reducing coil pipe heat exchanger as well as ultra-silencing fan coil pipe and soundproofing heat exchanger

Abstract

The invention relates to a silencing and noise-reducing coil pipe heat exchanger as well as an ultra-silencing fan coil pipe and a soundproofing heat exchanger, wherein the coil pipe heat exchanger is internally provided with a plurality of groups of bending-type heat exchange fins which are arranged along the air flowing direction and form a plurality of groups of air flowing channels in the coil pipe heat exchanger; micro holes with the diameters of 0.3-1.0mm are formed in the heat exchange fins at two sides of the air flowing channels in a left-right alternative way along the air flowing direction or micro holes with the diameters of 0.3-1.0mm are formed in the interval heat exchange fins; when air flows, air flow passes through the micro holes in a heat exchange fin on a plane vertical to the air flowing direction; and the micro holes and fin bodies at the opposite sides of the heat exchange fins at least locally form a micro hole plate sound absorption cavity body space. According to the silencing and noise-reducing coil pipe heat exchanger as well as the ultra-silencing fan coil pipe and the soundproofing heat exchanger, various complex and high-cost soundproofing devices are not required to be installed, and the silencing and noise-reducing coil pipe heat exchanger as well as the ultra silencing fan coil pipe and the soundproofing heat exchanger have the advantages of simple structure, obvious soundproofing effect, extremely low cost and the like.

Description

technical field [0001] The invention relates to a coil heat exchanger and corresponding equipment, in particular to a silent and noise-reducing coil heat exchanger, an ultra-quiet fan coil and a noise-eliminating heat exchanger. Background technique [0002] Fan coil units are usually installed in air-conditioning systems and are used to provide heat exchange between the air returning to the air-conditioning system from the space to be conditioned and the medium in the form of liquid, steam or gas. [0003] As the fan draws return air into the fan coil unit and over the heat exchanger coil, a lot of noise is bound to be generated. [0004] These noises are composed of aerodynamic noise and mechanical noise. Mechanical noise depends on the processing, dynamic balance and assembly accuracy of rotating parts, that is, on product quality; aerodynamic noise is only related to the static pressure and air volume of the air supply. Generally, the aerodynamic noise of fan coil unit...
