Description

Technical Field

[0001] This invention relates to a type of air cooler, specifically a portable air cooler with high-efficiency water evaporation cooling, belonging to the field of home appliances. Background Technology

[0002] According to statistics from the World Health Organization and several international research institutions, hundreds of thousands of people worldwide die each year from extreme heatwaves and heat-induced illnesses. A large proportion of these victims are impoverished, often unable to afford air conditioning and its associated electricity costs. During heat waves, temperatures often exceed 40°C, rendering electric fans ineffective in cooling the body. In such catastrophic weather, the health and even lives of impoverished populations are severely threatened.

[0003] In addition to the above situations, for certain high-temperature work positions in open spaces, including outdoor work in summer, traditional air conditioners are not suitable for use due to their high energy consumption and inconvenience in carrying them. Furthermore, traditional air conditioners have complex structures and require heat dissipation, making it difficult to make them into lightweight designs.

[0004] Traditional water curtain machines cool by evaporating moisture from a wet paper honeycomb structure. However, the specific surface area of ​​the paper honeycomb structure is relatively small, and the gaps in the paper wet curtain are relatively large, resulting in uneven distribution of the water film. The effective evaporation area utilization rate is less than 50%, leading to poor cooling effect. To achieve a certain required cooling capacity, a larger volume of paper honeycomb structure is needed, making it difficult to manufacture miniature models.

[0005] Currently, there are publicly available technologies that utilize evaporative cooling in honeycomb cells. However, this technology requires water pumps, nozzles, and electronic controllers to spray water onto the honeycomb cells. As is well known, water pumps are prone to failure, nozzles frequently become clogged, and electronic controllers are difficult for non-professionals to repair. If these components are used in products, in addition to significantly increasing manufacturing costs, they will also incur substantial after-sales service expenses. These costs will ultimately increase the price of the product, making it unaffordable for impoverished individuals. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a lightweight and compact air cooler with good cooling effect, low operating energy consumption, high reliability, convenient use and maintenance, and low cost.

[0007] The present invention can adopt the following technical solution:

[0008] A portable energy-saving air cooler includes a housing, a fan, a honeycomb structure, and a swing mechanism. The housing contains a sequentially connected air inlet, an air passage, and an exhaust zone. A water storage area is located below the air passage. The exhaust zone is equipped with the fan for external ventilation. The air passage includes a swing mechanism. The swing mechanism includes a fulcrum, a fixed plate, and a handle. The fixed plate is located inside the housing and connected to the handle. The fulcrum is located on the housing or a frame within the housing, and the honeycomb structure is mounted on the fixed plate. Moving the handle allows the fixed plate to swing around the fulcrum, positioning the honeycomb structure within the air passage or allowing it to fall into the water storage area.

[0009] The present invention can be further improved by the following measures to solve the problem:

[0010] A further improvement is that a water inlet is provided at the top of the casing.

[0011] Further improvements include: the honeycomb structure 3 is a zeolite-based honeycomb structure, a carbon molecular sieve honeycomb structure, or a nano-ceramic honeycomb structure.

[0012] A further improvement is that when the honeycomb body is in the air passage position, the direction of its honeycomb pores is consistent with the air passage direction.

[0013] Further improvements include: the housing is equipped with a locking mechanism that can lock the handle to keep the honeycomb body in the air passage position.

[0014] Further improvements include: the water storage area is equipped with a water level observation window.

[0015] Further improvements include: a pivot is provided at the corresponding position of the pivot point, and the fixing plate and handle are respectively fixed on the pivot.

[0016] A further improvement is that the handle is located outside the housing.

[0017] The above technical solution has the following technical effects:

[0018] 1. This invention can be made into a small and exquisite air cooler, suitable for personal use, and easy to carry for use outdoors and while traveling.

[0019] 2. The electrical components of this invention consist of only one fan, eliminating the need for a water pump and nozzles, thus reducing electrical malfunctions and nozzle clogging issues. Furthermore, its simple structure makes maintenance easy.

[0020] 3. This invention is energy-saving and inexpensive, achieving the effect of air conditioning at the price and power consumption of a regular electric fan, offering excellent value for money and making it suitable for low-income consumers. In areas lacking grid power, small solar cells or car power supplies can also meet power needs.

[0021] 4. The honeycomb material used in this invention has well-developed capillary channels and a huge specific surface area, which greatly improves the evaporation rate of water and the cooling COP can reach more than 2.5, which is close to the level of compressor cooling and far exceeds the cooling efficiency of traditional water curtain air conditioners with a COP of less than 1.5.

[0022] 5. The honeycomb structure used in this invention has a high evaporative cooling efficiency, and a large cooling capacity can be obtained with a small honeycomb structure, which meets the basic requirements for manufacturing micro-models.

[0023] 6. The refrigeration process of this invention does not require the compressor to work, thus saving energy; it eliminates the problem of external heat discharge; and it reduces environmental pollution by not using chemical refrigerants.

[0024] 7. In addition to having an air conditioning function, the present invention can adsorb dust and purify the air when the honeycomb channels are moist. Since the pore size of the honeycomb nanoscale base material is extremely small, several orders of magnitude smaller than the particle size of dust in the air, the micropores will not be blocked.

[0030] The present invention will now be described in detail with reference to specific embodiments.

[0031] Example 1: As shown in the attached document Figure 1-3As shown, a portable energy-saving air cooler includes a housing 1, a fan 2, a honeycomb structure 3, and a swing mechanism. The housing 1 has an air inlet 11, an air passage 12, and an exhaust zone 13 connected in sequence inside. A water storage area 8 is located below the air passage 12. The exhaust zone 13 is equipped with the fan 2 for external exhaust. The air passage 12 has a swing mechanism. The swing mechanism includes a fulcrum 6, a fixing plate 4, and a handle 5. The fixing plate 4 is located inside the housing and connected to the handle 5. The fulcrum 6 is located on the housing or a frame inside the housing, and the honeycomb structure 3 is mounted on the fixing plate 4. Moving the handle 5 allows the fixing plate 4 to swing around the fulcrum 6, positioning the honeycomb structure 3 within the air passage 12 or allowing it to fall into the water storage area 8.

[0032] In this example, the honeycomb structure 3 is a zeolite-based honeycomb structure. Alternatively, the honeycomb structure can be made using zeolite molecular sieve materials, carbon molecular sieve materials, or nano-ceramics as the base material.

[0033] In this example, the top of the housing 1 is provided with a water inlet 9.

[0034] In this example, the handle 5 is located outside the housing 1. The swing mechanism can be activated by the handle 5 located outside the housing 1, so that the honeycomb body 3 mounted on the fixed plate 4 is positioned within the air passage 12 or falls into the water storage area 8.

[0035] In this example, when the honeycomb body 3 is located in the air passage 12, the direction of its honeycomb pores is consistent with the air passage direction, and is horizontal or nearly horizontal. When the honeycomb body 3 is located in the water storage area 8, the direction of its honeycomb pores is vertical or nearly vertical.

[0036] In this example, the honeycomb structure 3 is arranged in the horizontal air passage duct 12, the exhaust zone 13 is connected to the air passage duct 12 in the horizontal direction, and the gaps other than the air passage duct 12 are sealed by the partition 7.

[0037] In this example, when the honeycomb body 3 is positioned in the air passage 12, the housing 1 is equipped with a latch to hold the handle 5 in place to prevent the honeycomb body 3 from falling due to gravity. The latch functions as a locking mechanism.

[0038] In this example, the water storage area 8 is equipped with a water level observation window.

[0039] One improvement is that a pivot is provided at the corresponding position of the fulcrum 6, and the fixing plate 4 and the handle 5 are respectively fixed on the pivot.

[0040] Working principle:

[0041] Example 1 Appendix Figure 1-3The workflow in this example is as follows: Before use, fill the water inlet 9 on the top of the housing with water. Stop filling the water when the water level reaches the upper limit line 10 of the observation window. Then, turn the handle 5 clockwise. When the handle 5 touches the limit device, turn the handle counterclockwise back to the initial limit position and lock the handle in place using the latch. After completing the above operations, the honeycomb body 3 will return to the air passage position 12 after being soaked and absorbing water. Then, start the fan to generate low-temperature cold air. When the air temperature is felt to rise again, turn the handle again in the same way to allow the honeycomb body to absorb water again, which will restore the cooling function. There is no need to turn off the fan during operation.

[0042] When the present invention is running continuously, the water absorption cycle of the honeycomb is generally about 30 minutes, depending on different climatic conditions. As long as the water can soak up more than two-thirds of the height of the honeycomb, the honeycomb can be basically saturated with water through self-permeation. Each time the water storage area is filled with water, it can meet the water absorption needs of the honeycomb more than 5 times. Therefore, the frequency of turning the handle and filling water is very low, which will not make people feel troubled.

[0043] The refrigeration principle of this invention is as follows: When air flowing through the air passage 12 enters the honeycomb pores of the zeolite molecular sieve using the suction force of the fan 2, the moisture on the pore wall is desorbed and forms water vapor, which is carried out by the wind. When the water vapor evaporates, it absorbs heat. Since the honeycomb has a large air passage area and the molecular sieve material has an extremely high specific surface area, coupled with the open microporous structure of the molecular sieve material, the dense capillaries formed from the inside to the outside will accelerate the permeation of internal moisture to the outside. After these factors are combined, the water vaporization efficiency in the molecular sieve is greatly improved. The latent heat required for the phase change of water vaporization is obtained by absorbing the sensible heat in the honeycomb. When the water vapor leaves the honeycomb pore wall, it has already transferred the cold energy to the honeycomb to cool it down. The air flowing through it is cooled by the cooled honeycomb and generates cold air.

[0044] Because the structure and performance of molecular sieve materials far exceed those of honeycomb paper materials, this invention, compared to water curtain air conditioners, can evaporate more water and obtain more latent heat of vaporization heat exchange with the same airflow. This is the main reason why the cooling efficiency and outlet air temperature of this invention are far superior to those of water curtain air conditioners. Therefore, this invention has a smaller volume under the same cooling capacity.

[0045] This product also has extremely high dust removal capabilities. The moist honeycomb channels can adhere to extremely small particles in the air, solving the problem in traditional air conditioners where the filtration effect deteriorates when the filter mesh is too large, and the mesh is prone to clogging when it is too small.

[0046] This example uses a manual method to soak the honeycomb cells to keep them moist, eliminating the need for additional costs for water pumps, nozzles, and electronic controllers. This also reduces after-sales service costs associated with the failure of these components. The only electrical component is a fan, and the probability of the fan failing is very low. As a result, the manufacturing cost of the small air cooler designed in this example can be reduced to tens of yuan, and its selling price can even be lower than that of ordinary household electric fans, making it affordable for low-income individuals and most impoverished people.

[0047] Example 2: As shown in the attached document Figure 4-5 As shown, a portable energy-saving air cooler includes a housing 1, a fan 2, a honeycomb structure 3, and a swing mechanism. The housing 1 has an air inlet 11, an air passage 12, and an exhaust zone 13 connected in sequence inside. A water storage area 8 is located below the air passage 12. The exhaust zone 13 is equipped with the fan 2 for external exhaust. The air passage 12 has a swing mechanism. The swing mechanism includes a fulcrum 6, a fixing plate 4, and a handle 5. The fixing plate 4 is located inside the housing and connected to the handle 5. The fulcrum 6 is located on the housing or a frame inside the housing, and the honeycomb structure 3 is mounted on the fixing plate 4. Moving the handle 5 allows the fixing plate 4 to swing around the fulcrum 6, positioning the honeycomb structure 3 within the air passage 12 or allowing it to fall into the water storage area 8.

[0048] The main difference between Example 2 and Example 1 is that Example 2 is a vertical structure and the air outlet and air inlet are on the same side.

[0049] In this example, the honeycomb structure 3 is made of nanoporous ceramic as the base material.

[0050] In this example, the top of the shell 1 is provided with a water inlet 9, and a water pipe is provided from the water inlet to introduce water into the water storage area 8.

[0051] In this example, the swing mechanism can be operated by a handle 5 located outside the housing 1, which can be turned to position the honeycomb body 3 mounted on the fixed plate 4 within the air passage 12 or to fall into the water storage area 8.

[0052] In this example, when the honeycomb body 3 is located in the air passage 12, the direction of its honeycomb pores is consistent with the air passage direction, and is horizontal or nearly horizontal. When the honeycomb body 3 is located in the water storage area 8, the direction of its honeycomb pores is vertical or nearly vertical.

[0053] In this example, the honeycomb structure 3 is set in the horizontal air passage duct 12, the exhaust zone 13 is connected to the air passage duct 12 in the vertical direction, and the gaps other than the air passage duct 12 are sealed by the partition 7.

[0054] In this example, when the honeycomb body 3 is in the air passage position 12, the housing 1 is provided with an elastic mechanism to fix the handle 5 to prevent the honeycomb body 3 from falling due to gravity.

[0055] In this example, the water storage area 8 is equipped with a water level observation window.

[0056] The main difference between Example 2 and Example 1 is that Example 2 has a vertical structure and the air outlet and air inlet are on the same side. The advantage is that the thickness of the shell can be further reduced, reducing the area occupied, and it will not block the air inlet when placed against the wall.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
