Description

Technical Field

[0001] The utility model relates to a V-shaped air cooler with a flow guide device, belonging to the technical field of air coolers. Background Art

[0002] Air cooler, also known as air-cooled condenser or air-cooled heat exchanger, is a heat exchanger that uses air as the cooling medium. The air cooler is mainly composed of an outer shell plate, a fan, and a fin tube bundle. Its main principle is that the cooled medium flows in the fin tube bundle, and the air flows outside the fin tube bundle. After the air is forced to flow through the fin tube bundle by the fan, it absorbs heat and its temperature rises, while the medium in the fin tube bundle loses heat and its temperature drops, thereby achieving the purpose of cooling the medium in the tube.

[0003] During the operation of a conventional V-type air cooler, since the fan is at the top, the wind speed in the fin area close to the fan is particularly fast and easily forms a dead angle. The wind speed in the fin area far away from the fan is very slow. Since the heat exchange of the air cooler mainly relies on the cross-sectional wind speed to improve the heat exchange efficiency, a fast wind speed will lead to large resistance and large air volume loss. A slow wind speed will cause the fan air volume to decrease, resulting in reduced heat exchange efficiency and poor heat exchange effect at the bottom of the fin.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] In view of the deficiencies in the background technology, the utility model provides a V-shaped air cooler with a guide device, which can extend part of the air volume in the upper area to the lower part, increase the wind speed in the lower area, make the wind speed of the fin tube bundle uniform, the air volume uniform, and the cross-sectional resistance uniform, thereby improving the overall heat exchange efficiency.

[0007] A V-shaped air cooler with a guide device comprises an equipment frame, a fin tube bundle with a V-shaped structure is installed inside the equipment frame, a fan is installed on the top of the equipment frame, and two symmetrically arranged guide devices are installed on both sides of the main body of the equipment frame.

[0009] Furthermore, the angle controller is fixedly connected to the equipment frame, and a plurality of adjustment holes distributed in an arc shape are provided on the angle controller.

[0014] Furthermore, a wet curtain structure is installed between the fin tube bundle and the guide device.

[0017] The window blades in the utility model can adjust the angle by pulling and pushing the operating rod. The operating rod drives the main pull rod, the sub-pull rod and the window blades to move in sequence during the push-pull swing process. After the operating rod is fixed in position, the swing angle of the window blade is fixed.
