AI Technical Summary

Technical Problem

The complex gas flow path can easily create eddies or blind spots inside the cabin, leading to excessive local temperature rise; the heat dissipation vents are easily clogged by dust, affecting the heat dissipation effect.

Method used

Design a high-efficiency heat dissipation wind turbine nacelle, comprising a load-bearing section, a heat dissipation section, a cleaning section, and an adjustment section. The drive component drives the control and cleaning components to move up and down reciprocally to clean the air inlet. Combined with an electric push rod to control the rotation of the baffle, the air passage is closed, and natural air is guided to concentrate into the heat dissipation module.

Benefits of technology

It effectively prevents dust from clogging the air inlet, increases the speed of natural air entry, enhances heat dissipation, and accelerates air circulation through fans and cooling systems to reduce the internal temperature of the cabin.

Abstract

The application discloses a high-efficiency heat dissipation type wind driven generator cabin, which comprises a bearing part, a heat dissipation part arranged on the bearing part, a cleaning part arranged on the heat dissipation part and an adjusting part arranged on the bearing part; the cleaning part is composed of a driving part, a control part and a cleaning part; the driving part is connected with the control part and controls the up-and-down reciprocating movement of the driving part; the control part is used for connecting the cleaning part and transmitting the kinetic energy provided by the driving part to the cleaning part; the equipment drives the control part to move through the driving part, so that the control part controls the cleaning part to realize the up-and-down reciprocating movement, the dust adhered to the air inlet is cleaned, and the air inlet is prevented from being blocked by the dust; in addition, the adjusting part is driven to move by the electric push rod, so that the adjusting part drives the baffle to rotate, the air paths on both sides are closed, the natural wind entering the air inlet enters the shell interior to be cooled, and thus the heat dissipation effect of the cabin body interior is increased.
