Description

Technical Field

[0001] The utility model relates to the technical field of evaporative air coolers, in particular to an evaporative air cooler. Background Art

[0002] Evaporative air coolers are widely used in industry and agriculture for cooling. Their main working principle is to use the heat absorption characteristics of water evaporation to reduce the air temperature through the contact between the evaporating medium and the air. This equipment has the advantages of energy saving, environmental protection, and significant cooling effect. Therefore, it has been widely used in greenhouses, livestock farms, factory workshops and other places where large areas need to be cooled.

[0003] Evaporative air coolers inhale outside air and use the evaporation process of water to cool down. However, there are some technical problems with current evaporative air coolers. First, after the air cooler inhales air, the air flow direction is relatively scattered and cannot effectively contact the heat exchange tubes, resulting in low heat exchange efficiency. Secondly, the outside air directly contacts the heat exchange tubes, which easily causes the temperature of the heat exchange tubes to rise too quickly, affecting the overall cooling effect and the service life of the equipment. These problems restrict the performance improvement of evaporative air coolers and cannot give full play to their cooling effect.

[0004] Based on this, those skilled in the art have proposed an evaporative air cooler. Utility Model Content

[0008] The first driving motor can drive the screw to rotate, and the screw can drive the guide plate to move when rotating. The guide plate has an outward-expanding air collecting port, and the guide plate is configured in a trumpet shape, so that air enters from a large inlet and flows to a small outlet, which can speed up the air flow and thus reduce the air temperature in advance. Moreover, through the rotation of the screw, the air can be evenly delivered to the outside of the heat exchange tube, thereby ensuring that the heat exchange tube can be evenly in contact with the air.

[0009] In a preferred solution, two vertical plates are symmetrically fixedly connected inside the shell and on one side of the fixed plate, and a heat exchange tube is arranged between the two vertical plates. The heat exchange tube is arranged in a multi-layer paper clip structure.

[0011] In a preferred solution, evaporation plates are equidistantly arranged outside the heat exchange tube and between two vertical plates, and the evaporation plates are made of copper.

[0012] The heat obtained by the heat exchange tube and the air will evaporate through the evaporator plate, thus completing the heat transfer.

[0013] In a preferred solution, a protective cover is fixedly connected to the outer side of the housing, a second drive motor is fixedly connected to the outer side of the protective cover, and an output end of the second drive motor extends to the inside of the protective cover and is fixedly connected to a fan.

[0014] The fan is driven to rotate by the second driving motor, and the rotation of the fan drives the air to flow.

[0015] In a preferred embodiment, two notches are provided on the back of the shell, one end of the heat exchange tube is fixedly connected to the water inlet pipe and extends to the outside of the shell through the corresponding notch, and the other end of the heat exchange tube is fixedly connected to the water outlet pipe and extends to the outside of the shell through the corresponding notch.

The guide plate is provided with an outward-expanded air collecting port, and the guide plate is configured in a trumpet shape, so that air enters from the large inlet and flows to the small outlet, which can speed up the air flow, thereby reducing the air temperature in advance, and through the rotation of the screw rod, the air can also be evenly delivered to the outside of the heat exchange tube, thus ensuring that the heat exchange tube can be evenly in contact with the air, which can effectively extend the heating speed of the heat exchange system of the evaporative air cooler, and is more convenient to use.
