AI Technical Summary
In the prior art, the cooler cannot work when the small motor is being repaired or replaced, which affects the normal operation of the large motor, resulting in increased temperature and shortened service life.
A dual-channel air outlet device is designed, which uses two independent air blowing devices. Each air outlet is equipped with a self-hanging shutter and a guide rail. One is used as the main and the other as the backup. The two are switched through the control room to ensure the continuous operation of the cooler.
When a blower unit fails, it can immediately switch to the backup unit, avoiding the cooler shutdown and protecting the normal operation and service life of the large motor.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of machinery, in particular to a cooler for large motors, and especially to a dual-channel air outlet device. Background Art
[0002] As the main heat exchange component of the motor, the air-to-air cooler is an important product to maintain the operation of the motor, directly affecting the temperature rise, power and life of the motor. The IC616 air-to-air cooler is a commonly used cooling device. The IC616 air-to-air cooler uses an external fan device to blow the surrounding air towards the heat exchange tubes. After the cold air contacts the hot pipes, heat is transferred to cool the hot substances in the pipes. During the operation of the cooler, the small motor supporting the external air duct fan device often fails due to various reasons such as the use environment and working fatigue. At this time, the small motor needs to be repaired or replaced. When repairing or replacing the small motor, the cooler needs to be in a non-heat exchange state, that is, stop working. In this way, the heat dissipated by the large motor cannot be cooled and exchanged anymore, and the insulating layer inside the large motor will be affected by the temperature rise, and the efficiency and service life of the large motor will also be affected. Summary of the Invention
[0003] The purpose of the utility model is to provide a dual-channel air outlet device, and this dual-channel air outlet device is to solve the technical problem that the cooler cannot work when repairing or replacing the small motor in the prior art, which affects the normal operation of the large motor.
[0004] A dual-channel air outlet device of the utility model includes a bracket. A volute is arranged on the side of the bracket. A first motor and a second motor are arranged at intervals on the side of the volute. A first impeller and a second impeller are arranged in the volute. The output shafts of the first motor and the second motor are respectively connected to the first impeller and the second impeller. A first air collecting port and a second air collecting port are respectively arranged on one side of the first impeller and the second impeller in the volute. A first air outlet and a second air outlet are arranged on the side of the volute. The first air outlet is communicated with the first air collecting port, and the second air outlet is communicated with the second air collecting port. A first one-way ventilation device is arranged in the first air outlet, and a second one-way ventilation device is arranged in the second air outlet.
[0005] Further, the first one-way ventilation device and the second one-way ventilation device are self-closing louvers.
[0006] Further, guide rails for installing self-closing louvers are respectively arranged in the first air outlet and the second air outlet.
[0007] Further, covers are arranged on the outer sides of the first air outlet and the second air outlet.
[0008] Compared with existing technologies, this invention offers significant and positive advantages. During on-site operation, only one blower needs to be activated, while the other serves as a backup. If the operating motor malfunctions, the control room immediately stops the faulty motor and activates the backup motor, ensuring uninterrupted operation of the cooler. Therefore, compared to existing air outlet systems, this design effectively avoids the impact of repairing or replacing the small motor, enhancing the reliability of the large motor. The cover design also allows for the inspection and replacement of the self-closing louvers even during operation. Attached Figure Description

[0012] The present invention will be further described below with reference to embodiments, but the present invention is not limited to these embodiments. Any similar variations using the present invention should be included within the protection scope of the present invention. The use of directions such as up, down, front, back, left, right, center, inside, and outside in the present invention is only for the convenience of clear description and is not intended to limit the technical solution of the present invention.
[0013] like Figure 1-Figure 3 As shown, a dual-channel air outlet device of this utility model includes a bracket 4, a volute 7 is provided on the side of the bracket 4, a first motor 1 and a second motor 10 are provided at intervals on the side of the volute 7, a first impeller 2 and a second impeller are provided in the volute 7, the output shafts of the first motor 1 and the second motor 10 are respectively connected to the first impeller 2 and the second impeller, a first air collecting port 3 and a second air collecting port are respectively provided on one side of the first impeller 2 and the second impeller in the volute 7, a first air outlet 5 and a second air outlet are provided on the side of the volute 7, the first air outlet is connected to the first air collecting port 3, the second air outlet is connected to the second air collecting port, a first one-way ventilation device is provided in the first air outlet, and a second one-way ventilation device is provided in the second air outlet.
[0014] Furthermore, the first one-way ventilation device and the second one-way ventilation device are self-closing louvers 9.
[0015] Furthermore, each of the first air outlet 5 and the second air outlet is provided with a guide rail 8 for installing the self-closing louver 9.
[0016] Furthermore, a cover plate 6 is provided on the outer side of the first air outlet 5 and the second air outlet.
[0017] Specifically, in this embodiment, the volute 7, the first motor 1, the second motor 10, the first impeller 2, the second impeller, the first air inlet 3, the second air inlet, the first one-way ventilation device, the second one-way ventilation device, the self-closing louver 9, the guide rail 8, etc., all adopt well-known solutions in the prior art, which are already known to those skilled in the art, and will not be described in detail here.
[0018] The working principle of this embodiment is as follows:
[0019] The motor, impeller, air inlet, and volute 7 form a blower. Two identical blowers are connected in parallel, each equipped with self-closing louvers 9. When there is airflow at the first air outlet 5 and the second air outlet, the self-closing louvers 9 open; otherwise, they close. This effectively controls the first and second air outlets, ensuring they do not interfere with each other and that there is no loss of airflow. During on-site operation, only one blower needs to be operated, while the other serves as a backup. If the operating motor fails, the control room immediately stops the faulty motor and starts the backup motor, thus ensuring uninterrupted operation of the cooler. Therefore, compared to existing air outlet systems, this design more effectively avoids the impact of repairing or replacing a small motor, enhancing the reliability of the large motor.
[0020] The self-closing louver 9 is inserted into the first air outlet via the guide rail 8, making the installation more stable and reliable. The design of the cover plate 6 allows for inspection and replacement of the self-closing louver 9 even while it is in operation.
