Low-noise air source heat pump outdoor heat exchange device

Abstract

The invention discloses a low-noise air source heat pump outdoor heat exchange device, and relates to the technical field of low-noise heat exchange devices. The heat exchanger device comprises a heatexchanger box, and a heat exchanger box shell comprises a three-layer noise elimination and sound insulation layer; the three-layer noise elimination and sound insulation layer sequentially comprisesa glass fiber silencing plate, a butyronitrile rubber-based sound insulation layer and an asphalt plate damping sound insulation layer from the inner wall to the outer wall of the heat exchanger box;a thickened silencing layer is arranged in the middle of the inner side of the heat exchanger box; the thickened silencing layer and the other side of the inner side wall of the heat exchanger box form a narrow flow channel cavity; the narrow flow channel cavity divides the heat exchanger box into an upper air inlet expansion static pressure cavity and a lower air outlet expansion static pressurecavity. According to the device, the three-layer noise elimination and sound insulation layer composed of the glass fiber silencing plate, the butyronitrile rubber-based sound insulation layer and the asphalt plate damping sound insulation layer is adopted in the heat exchanger box, so that noise elimination and sound insulation are achieved. Meanwhile, an air inlet and an air outlet adopt the static pressure box type design with an increased flow channel area, and the noise of a centrifugal fan is lowered.

Description

technical field [0001] The invention belongs to the technical field of low-noise heat exchange devices, in particular to a low-noise air source heat pump outdoor heat exchange device. Background technique [0002] The air source heat pump system is often used in the air conditioning system to bring people a comfortable living environment, but the air source heat pump system will generate noise during the operation. The noise of the air source heat pump system mainly comes from the fan and the compressor; and in the heat exchange process of the air source heat pump system, the fan is the main cause of noise. [0003] The present invention is devoted to developing a low-noise air source heat pump outdoor heat exchange device, which is used to solve the problem of high noise of the centrifugal fan in the existing heat exchange device. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a low-noise air source heat pump outdoor heat exchange de...

Problems solved by technology

[0004] The purpose of the present invention is to provide a low-noise outdoor heat exchange device for an air source heat pump. The shell of the heat exchange box adopts three layers of sound attenuation: glass fiber sound-absorbing board, nitrile rubber-based sound-insulating layer, and asphalt-board damping and sound-insulating layer. Layer; realize sound attenuation and sound insulation; at the same time, both the air inlet and the air outlet adopt the static pressure box design with enlarged flow channel area, which solves the problem of high noise of the centrifugal fan in the existing heat exchange device
