Technical Field
The utility model relates to a cooler, a high-efficient low noise motor air-to-air cooler specifically says so.
Background
When the high-power motor works, the temperature of the motor can rise due to continuous work, and the motor has certain potential safety hazard due to overhigh temperature, so that the output power of the motor is influenced, and the service life of the motor is prolonged. Therefore, the motor is now equipped with a motor cooling device to maintain the motor operating in a normal temperature range. The design of the air-air cooler of the early motor has little attention to technical indexes such as noise, a flowing state and the full-pressure efficiency of the internal air path circulating fan, and along with the improvement of science and technology and the improvement of user requirements, the demand of the cooler with compact structure, low noise and high efficiency is more and more strong.
Disclosure of Invention
The utility model provides a simple structure, can effectively improve the total pressure efficiency of fan in the wind path, compromise cooling effect, noise reduction's high-efficient low noise motor air-air cooler.
The utility model adopts the technical proposal that: the utility model provides a high-efficient low noise motor air-air cooler, includes the box, divide into down the middle air inlet chamber of air inlet and the left and right both sides limit air-out chamber of air-out down in the box, middle air inlet chamber upper portion is equipped with cooling blower and outer wind way export respectively through centrifugal fan UNICOM's left and right both sides limit air-out chamber upper portion, box both sides, the heat exchange tube in air inlet chamber, both sides air-out chamber in the middle of many cross-under boxes of UNICOM between cooling blower and the outer wind way export, its characterized in that: the front side and the rear side of the centrifugal fan are respectively provided with two guide plates which are symmetrical with the center of the centrifugal fan, each guide plate comprises a front arc-shaped guide section and a rear arc-shaped guide section, the connecting part between the front arc-shaped guide section and the rear arc-shaped guide section is nearest to the center of the centrifugal fan, and the outer sides of the front arc-shaped guide section and the rear arc-shaped guide section face towards the air outlet cavities on the left side and the right side respectively.
Further, the front and rear arc guide flow sections have the same length.
Furthermore, the front arc-shaped guide section and the rear arc-shaped guide section are different in length, and the connecting part between the front arc-shaped guide section and the rear arc-shaped guide section deviates from the front and rear directions of the center of the centrifugal fan.
Furthermore, a corner arc-shaped guide plate is further arranged in the side air outlet cavity, and the outer side of the corner arc-shaped guide plate, which corresponds to the front arc-shaped guide section and the rear arc-shaped guide section, is arranged at a corner at the upper part of the side air outlet cavity.
The utility model discloses set up the guide plate in the front and back side of centrifugal fan, the front and back arc-shaped guide section outside double outlet of guide plate will leave the gas guide left and right sides limit air-out cavity of centrifugal fan impeller, and change a part of kinetic energy of gas into static pressure, the direction of arc structure ensures that the flow state is good, the effect of taking off and landing noise, can promote the total pressure efficiency of interior centrifugal fan greatly simultaneously, improve the refrigeration effect; the side air outlet cavity is provided with a corner arc-shaped guide plate corresponding to the air outlet guide of the guide plate, so that the flowing state is improved, the internal loss is reduced, and the refrigeration effect and the noise are further improved.
