Detailed Description
The invention is described in further detail below with reference to fig. 1-3.
The embodiment of the invention discloses a cooler for exhaust.
Referring to fig. 1,2 and 3, a cooler for exhaust gas includes a heat dissipation assembly 1 and a ventilation duct 2, wherein the heat dissipation assembly 1 has a wind source; the air outlet of the ventilating duct 2 faces to the parts needing heat dissipation; the wind blown out from the wind source is blown to the heat dissipation parts through the ventilation pipeline 2. Wind is blown to the heat dissipation parts through the wind source, the heat dissipation parts are dissipated, and the heat dissipation effect is improved.
The wind source comprises a fan 11 which is driven to rotate, and wind generated by driving the fan 11 blows to the heat dissipation parts through the ventilation pipeline 2. An air winding seat groove 6 is arranged between the fan shell 3 and the ventilation pipeline 2, the air winding seat groove 6 is an annular groove, an air jet opening 61 is formed in the air winding seat groove 6, and air generated by driving the fan 11 enters the air winding seat groove 6 through the fan shell 3 and then is blown to heat dissipation parts through the ventilation pipeline 2.
In this embodiment, the ventilation duct 2 is a Lafael air tube. The ventilation duct 2 is fixedly arranged on the exhaust pipe 7 by a fixing rod 5. The convergent air inlet of the Laval air pipe faces the air jet orifice 61 of the air mat winding groove 6, the diffusion jet pipe of the Laval air pipe faces the heat dissipation part, the air entering the Laval air pipe passes through a pipeline which is contracted first and then expanded, the front half part of the pipeline is contracted to a narrow throat from large to small, the narrow throat is then expanded to a throttle valve from small to large, the air in the pipeline flows into the front half part of the pipeline by vacuum negative pressure, and is ejected from the rear half part after passing through the narrow throat.
The blade of fan 11 is metal blade, be provided with fan casing 3 on the air pipe 2, fan casing 3 is used for gathering together fan 11 by the wind that drives the production and guides to air pipe 2 through the installation pole installation on fan casing 3 to fan casing 11's blade, be provided with permanent magnet 4 on the fan casing 3, permanent magnet 4 is used for magnetizing metal blade, permanent magnet 4 is fixed to be set up in fan casing 3 and is close to blast pipe 7 one side, the mounted position of permanent magnet 4 is according to blast pipe 7's temperature height, can suitably make the adjustment, maintain higher magnetization efficiency.
There is a movement gap between the fan housing 3 and the exhaust duct 7. There is a movement gap between the fan housing 3 and the exhaust duct 7 in the range of 1mm to 5mm, the fan housing 3 is close to the exhaust duct 7 with as little clearance as possible, but without interference, in this embodiment the movement gap is 2mm.
The opening of the air injection port 61 is inclined in a direction approaching the air pipe, so that the air quantity entering the ventilation duct 2 is increased, and the air quantity loss is reduced.
The permanent magnet 4 is adopted to magnetize the local metal fan 11 blades, the fan 11 blades are subjected to the magnetic force action and are static, but after the blades are close to the exhaust pipe 7, the metal blades are demagnetized under the action of the high temperature of the exhaust pipe 7, so that the whole fan 11 is stressed unevenly and rotates, after the fan 11 rotates, the sucked air enters the fan 11 shell and then upwards enters the air winding seat groove 6 and is sprayed out from the air spraying port 61, the front end air of the Laval air pipe is ejected and enters the Laval air pipe to finish the first air volume multiplication, then the air passes through the Laval air pipe, and the pressure can be converted into kinetic energy due to the pressure difference at the front end and the rear end of the Laval air pipe, so that the air flow velocity around the Laval air pipe is increased, the cooling and heat dissipation effects of surrounding parts are increased, and no additional power source is needed, and the Laval air pipe can be arranged at any position of the exhaust pipe 7 to increase heat dissipation.
In addition, compared with the Laval air pipe, the fan 11 is closer to the advancing direction of the vehicle, the fan 11 is of an open design, the air inlet of the fan 11 and the air inlet of the Laval air pipe are in a positive pressure state in the vehicle road surface running process, the air outlet of the fan 11 and the air outlet of the Laval air pipe can be obviously increased, and the radiating effect is improved.
