Heat-dissipating and sound-insulating high-pressure draught fan

Abstract

The invention relates to the technical field of draught fans, in particular to a heat-dissipating and sound-insulating high-pressure draught fan. The heat-dissipating and sound-insulating high-pressure draught fan comprises a sound-insulating box, a high-pressure draught fan body mounted in the sound-insulating box and an exhaust fan mounted in the box. The sound-insulating box comprises a sound-insulating plate and sound-insulating walls arranged to surround the sound-insulating plate. An accommodating cavity is formed by enclosing of the sound-insulating walls. The accommodating cavity is divided into an exhaust cavity and a working cavity by a partition plate. The high-pressure draught fan body and the exhaust fan are mounted in the working cavity. The exhaust fan is used for exhaustingheat of the working cavity to the exhaust cavity. The bottom of the working cavity is provided with an air inlet hole. The side wall of the exhaust cavity is provided with an exhaust hole. Accordingto the heat-dissipating and sound-insulating high-pressure draught fan, the exhaust cavity and the working cavity are formed in the sound-insulating box, the high-pressure draught fan body arranged inthe working cavity sucks external low-heat air from the air inlet hole of the working cavity under action of the exhaust fan, and exhausts hot air in the working cavity to the exhaust cavity, it is ensured that the ambient temperature of the working cavity is low, and the sound-insulating effect is also achieved while heat dissipating is ensured.

Description

Technical field [0001] The invention relates to the technical field of fans, in particular to a heat dissipation and sound insulation high-pressure fan. Background technique [0002] The fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. Fan is the abbreviation for gas compression and gas transportation machinery in China. Generally speaking, fans include ventilator, blower and wind generator. [0003] Fans are widely used for ventilation, dust exhaust and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and induced air for boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances ; Drying and selective delivery of grains, air source of wind tunnel and inflation and propulsion of hovercraft. [0004] As the use of fans becomes more and more widespread, the amount of ventilation for the fans a...

AI Technical Summary

Problems solved by technology

[0004] As the fan is used more and more widely, the ventilation volume of the fan is also increased, so a high-pressure fan is needed, but when the ventilation volume increases, a series of problems will arise. The motor that drives the fan rotates The heat dissipation problem and the noise problem of the motor rotation are two contradictory problems. The heat dissipation problem needs to increase the communication between the inside of the equipment and the outside world, and the noise problem needs to reduce the communication between the inside and the outside of the equipment. Therefore, the existing high-pressure fans cannot Solve the problem of heat dissipation and sound insulation at the same time
