Description

Technical Field

[0001] This utility model relates to an air-to-water generator, and more particularly to a heat exchange element for an air-to-water generator. Background Technology

[0002] Most air-to-water generators on the market operate on the principle of condensation. They utilize the vaporization phase change of a low-temperature, low-pressure liquid refrigerant within the evaporator tubes to cool the air on the outer surface of the evaporator (which is one of the heat exchange elements), causing the water vapor to condense into liquid water, which is then collected to form a water source. In this process, the heat exchange element, as a key component for achieving heat exchange, directly affects the overall efficiency of the air-to-water generator. However, existing air-to-water generators have poor condensation efficiency during the water production process and consume relatively high power. Utility Model Content

[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a heat exchange element for an air-to-water generator.

[0004] The present invention adopts the following technical solution.

[0005] A heat exchange element for an air-to-water generator includes two first heat exchange plates and one second heat exchange plate. The second heat exchange plate is disposed between the two first heat exchange plates and is attached to the two first heat exchange plates. Both the upper and lower ends of the first and second heat exchange plates are inclined surfaces. When one side of one first heat exchange plate is attached to the other side of the second heat exchange plate, it forms several first heat exchange air ducts. When the other side of the other first heat exchange plate is attached to the other side of the second heat exchange plate, it forms several second heat exchange channels.

[0006] In order to form a stable first heat exchange channel, a first ridge is provided on the surface of the first heat exchange plate, and a protrusion is provided at each end of the first ridge.

[0007] To ensure better adhesion between the first heat exchanger and the second heat exchanger, a first bonding strip and a second bonding strip are provided on the surface of the first heat exchanger. Both the first bonding strip and the second bonding strip are provided on the side of the first heat exchanger with the first protrusion, and both ends of the first bonding strip and the second bonding strip are provided with protrusions.

[0008] Preferably, the side of the first heat exchange fin away from the first bonding strip is provided with a first groove and a second groove.

[0009] In order to form a stable second heat exchange channel, the surface of the second heat exchange plate is provided with a first air guide strip and a second air guide strip. Both ends of the first air guide strip and the second air guide strip are provided with a first locking block, and the first locking block can be locked into the first groove.

[0010] To ensure better fit between the second heat exchanger and the first heat exchanger, two retaining strips are provided on the surface of the second heat exchanger, and two second retaining blocks are provided at both ends of the two retaining strips. Both second retaining blocks can be engaged in the first groove and the second groove.

[0011] Preferably, the side of the second heat exchange fin away from the first air guide strip is provided with a slot, and both protrusion one and protrusion two are adapted to the slot.

[0012] To improve the quality of water production, both the first and second heat exchange plates are made of food-grade PS material.

[0013] To improve heat exchange efficiency, the number of first heat exchange channels is two, and the number of second heat exchange channels is no less than four.

[0014] Beneficial effects: This utility model can increase the contact heat exchange area and contact time between room temperature air and low temperature air during the water production process, which can improve the condensation efficiency. Compared with traditional air-to-water generators, the air-to-water generator with the heat exchange element of this application can significantly increase the amount of water produced per unit time. At the same time, it has lower power consumption and is more environmentally friendly. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Combination Figures 1-7 As shown in the figure, a heat exchange element of an air-to-water generator includes two first heat exchange plates 1 and one second heat exchange plate 2. The second heat exchange plate 2 is disposed between the two first heat exchange plates 1 and is attached to the two first heat exchange plates 1. Both the upper and lower ends of the first heat exchange plates 1 and the second heat exchange plate 2 are inclined surfaces. When one side of one first heat exchange plate 1 is attached to the second heat exchange plate 2, two first heat exchange air ducts 3 are formed. When the other side of the other first heat exchange plate 1 is attached to the second heat exchange plate 2, six second heat exchange channels 4 are formed. The surface of the first heat exchange plate 1 is provided with a first protrusion 5, and the two ends of the first protrusion 5 are respectively provided with protrusions 6. The surface of the first heat exchange plate 1 is provided with a first bonding strip 7 and a second bonding strip 8. The first bonding strip 7 and the second bonding strip 8 are both provided on the side of the first heat exchange plate 1 with the first protrusion 5, and both ends of the first bonding strip 7 and the second bonding strip 8 are provided with protrusions 9. The first heat exchange plate 1 has a first groove 10 and a second groove 11 on the side away from the first bonding strip 7. The surface of the second heat exchange plate 2 is provided with a first air guide strip 12 and a second air guide strip 13. Both ends of the first air guide strip 12 and the second air guide strip 13 are provided with a first locking block 14, and the first locking block 14 can be locked into the first groove 10. The second heat exchange plate 2 has two retaining strips 15 on its surface, and each end of the two retaining strips 15 has two second retaining blocks 16, which can be engaged in the first groove 10 and the second groove 11. The second heat exchange plate 2 has a slot 17 on the side away from the first air guide strip 12, and both the first protrusion 6 and the second protrusion 9 are adapted to the slot 17. Both the first heat exchange plate 1 and the second heat exchange plate 2 are made of food-grade PS material.

[0026] In another implementation, the number of first heat exchange channels 3 is three, and the number of second heat exchange channels 4 is not less than four, including but not limited to four, five, seven, or eight.

[0027] In use, one side of the first heat exchange plate 1 is attached to the other side of the second heat exchange plate 2. The first protruding strip 5, the first bonding strip 7, and the second bonding strip 8, together with one side of the second heat exchange plate 2, form a first heat exchange air duct 3, facilitating the flow of room temperature air through the first heat exchange air duct 3. At the same time, since both ends of the first heat exchange plate 1 and the second heat exchange plate 2 are beveled, the contact area with room temperature air is increased, further facilitating the flow of room temperature air into the first heat exchange air duct 3. Then, the other side of the first heat exchange plate 1 is attached to the other side of the second heat exchange plate 2. The first air guide strip 12, the second air guide strip 13, and the retaining block, together with the first heat exchange plate 1, form a second heat exchange channel 4, facilitating the flow of low temperature gas into the second heat exchange channel 4. During the water production process, the first heat exchange duct 3 and the second heat exchange channel 4 are separated only by the second heat exchange plate 2, thereby improving the heat exchange between the first heat exchange duct 3 and the second heat exchange channel 4, which can increase the efficiency of water production. Compared with traditional air-to-water generators (traditional air-to-water generators do not have the heat exchange element in this solution installed), the water production per unit time can be increased by about 20%.

[0028] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
