[0036] Reference Figure 1-5 ,

[0037] A dual-condition evaporative cooling device includes: a main body 1, a fan device 2, and a drive pump 3.

[0038] The main body 1 of the device is provided with an installation chamber 11 for mounting a heat exchanger 4, an air inlet 12 communicating with the installation chamber 11, and an air outlet 13 communicating with the installation chamber 11. A fan device 2 is disposed at the air outlet 13. The main body 1 also has a water storage chamber 14, in which water is pumped downwards from above the heat exchanger 4 by a drive pump 3. Multiple fluorinated water heat exchange elements 5 are disposed on the heat exchanger 4. The fluorinated water heat exchange elements 5 are fluorinated water heat exchange fins, which are fixed to the heat sinks on the heat exchanger 4. The fan causes external air to pass sequentially through the air inlet 12, the installation chamber 11, and the air outlet 13. As the air passes through the heat exchanger 4 in the installation chamber 11, it carries away the cold or heat energy from the heat exchanger 4. The drive pump 3 sprays water onto the heat exchanger 4, which can take away more heat from the heat exchanger 4 by evaporation of water. In addition, water has a large specific heat capacity, which can exchange more heat with the heat exchanger 4 when the temperature of the heat exchanger 4 is low, so that the cold energy on the heat exchanger 4 can be quickly removed.

[0039] Specifically, a water spray pipe 6 is installed above the heat exchanger 4, and the water spray pipe 6 is connected to the drive pump 3; the water spray pipe 6 is provided with multiple water spray holes, which spray water onto the heat exchanger 4. By utilizing the multiple water spray holes on the water spray pipe 6, water is sprayed over a large area of ​​the heat exchanger 4, increasing the efficiency of heat exchange.

[0040] Specifically, a guide rope 7 is provided on the water spray pipe 6; the guide rope 7 is wrapped around the water spray holes on the water spray pipe 6; the guide rope 7 is at least partially in contact with the heat exchanger 4 or the fluorine-water heat exchanger 5. By using the guide rope 7, some water can flow downwards along the guide rope 7, which is made of cotton or linen. Water will remain on the guide rope 7, and since the guide rope 7 is in contact with the heat exchanger 4 or the fluorine-water heat exchanger 5, it ensures that water is always in close contact with the heat exchanger 4 or the fluorine-water heat exchanger 5, increasing the contact area between the heat exchanger 4 or the fluorine-water heat exchanger 5 and the water, thus improving heat exchange efficiency.

[0041] Specifically, the guide rope 7 is partially submerged in the water storage chamber 14. Water will then flow back into the water storage chamber 14 along the guide rope 7, achieving water recycling. Furthermore, the submersion of the guide rope 7 in the water storage chamber 14 also utilizes its own water absorption properties or the principle of siphoning to keep the guide rope 7 constantly moist.

[0042] Specifically, the water storage chamber 14 is located below the installation chamber 11; a filter screen 8 is installed above the water storage chamber 14, and the water storage chamber 14 is connected to the installation chamber 11 through the filter screen 8. The filter screen 8 filters dust and impurities in the water. After water is sprayed onto the heat exchanger 4, the water falls onto the filter screen 8 and flows back into the water storage chamber 14 through the filter screen 8. The filter screen 8 filters the water, ensuring that the water returning to the water storage chamber 14 is free of dust and impurities. This prevents dust and impurities from adhering to the heat exchanger 4 when they are present in the outside air. The water spraying onto the heat exchanger 4 washes off the dust and impurities, preventing them from entering the water storage chamber 14, thus better ensuring the water quality in the water storage chamber 14 and also better flushing the heat exchanger 4 of dust and impurities.

[0043] Specifically, the filter screen 8 is positioned obliquely above the mounting chamber 11; a receiving box 9 is provided at the lower end of the filter screen 8. The oblique positioning of the filter screen 8 allows dust and impurities on it to be flushed into the receiving box 9 along the inclined direction, achieving dust and impurity recovery. Additionally, the receiving box 9 can be connected to the water storage chamber 14 via another filter screen 8, allowing water in the receiving box 9 to flow back into the water storage chamber 14.

[0044] Specifically, an elastic component 10 is provided at the upper end of the filter screen 8; the lower end of the filter screen 8 is hinged to the water storage chamber 14 or the mounting chamber 11. The elastic component 10 is a spring. When the filter screen 8 becomes clogged, the speed at which water passes through the filter screen 8 slows down, and the weight of the water on the filter screen 8 increases, causing the filter screen 8 to press down on the elastic component 10, resulting in partial movement of the filter screen 8. At this time, controlling the speed or time of water spraying by the drive pump 3 can realize the up and down movement of the filter screen 8, which is beneficial for shaking off the dust and impurities clogging the filter screen 8.

[0045] Specifically, the air outlet 13 is perpendicular to the air inlet 12. A water supply pipe 15 is connected to the external water storage chamber 14. The water supply pipe 15 facilitates the replenishment of water into the water storage chamber 14.

[0046] Specifically, the guide rope 7 is elastic, and the portion of the guide rope 7 in the heat exchanger 4 has a rebound section. The rebound section is the elastic part of the guide rope 7, which can be in a bent and rebound state or in a stretchable fabric state. The guide rope 7 is fixed to the filter screen 8, and the guide rope 7 also passes through the filter holes on the filter screen 8 and reaches the bottom of the water storage chamber 14.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
