Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, and in particular to an energy-saving cooling device without a compressor for a closed space. Background Art

[0002] At present, during the hot summer period, the use of air conditioners can bring a cool and comfortable feeling to people's living environment. In response to the demand for air conditioning in residential places, office places and public places, the utilization rate of air conditioners is also gradually increasing. The air conditioner currently widely used is a compressor refrigeration air conditioner. The working principle of this air conditioner is: the compressor compresses the gaseous refrigerant into a high-temperature and high-pressure gas, and sends it to the condenser for cooling. After cooling, it becomes a medium-temperature and high-pressure liquid refrigerant and enters the drying bottle for filtration and dehumidification. The medium-temperature liquid refrigerant is throttled and reduced in pressure by the expansion valve to form a low-temperature and low-pressure gas-liquid mixture. It absorbs heat in the air through the evaporator and vaporizes into a gas, and then returns to the compressor to continue compression and refrigeration cycle.

[0003] Based on the working principle of existing compressor refrigeration air conditioners, a compressor must be used. Such usage will easily cause the following problems:

[0004] 1. The power consumption of the compressor is high, which causes the annual power supply demand to increase rapidly;

[0005] 2. The assembly and use of the compressor, air conditioner and pipeline will take up more space, and the compressor will generate a lot of noise when running;

[0006] 3. When the compressor is running, it will generate high-temperature hot air and discharge it to the outside, causing the outdoor temperature to rise abnormally;

[0007] Based on the working principle and existing problems of the above-mentioned compressor refrigeration air-conditioning, it is difficult to install and use it in closed spaces such as residential underground parking lots and elevator lobbies in underground parking lots. First, the pipeline between the compressor and the air conditioner needs to be greatly extended, and the installation cost of such pipelines is high. Secondly, the heat generated by the compressor may flow back and accumulate in the closed space, causing the internal temperature to be higher. Thirdly, it is impossible to install compressor refrigeration air-conditioning in such a small closed space as the elevator lobby in the underground parking lot. Users have to endure high room temperature while waiting for the elevator, which can easily lead to heatstroke. Summary of the invention

[0008] The purpose of the utility model is to provide an energy-saving and cooling device for a closed space without a compressor, which can achieve effective cooling without using a compressor, reduce energy consumption costs, and reduce the occupation of the used space.

[0009] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] A compressor-free energy-saving and cooling device for a closed space comprises a box body, wherein a plurality of aluminum heat exchange tubes arranged in parallel are arranged in the box body, one end of the aluminum heat exchange tube is arranged on one outer wall of the box body, the other end of the aluminum heat exchange tube is arranged on the other outer wall of the box body, a plurality of grooves are arranged on the outer surface of the aluminum heat exchange tube, air guide ducts are arranged on both sides of the box body, the air guide ducts include ventilation ducts and fans, one end of the ventilation duct is arranged on the side of the box body and is interconnected with each aluminum heat exchange tube, the fan is arranged at the other end of the ventilation duct, and the other two sides of the box body are provided with pipeline interfaces connected to the interior thereof.

[0011] Furthermore, the fans are provided in plurality and are arranged at the other end of the ventilation duct via a mounting plate, and the plurality of fans are distributed at equal distances.

[0012] Furthermore, the other end cover of the ventilation pipe is provided with a filter, and the fan is located on the inner side of the filter.

[0013] Furthermore, the inner diameter of the aluminum heat exchange tube is set to 10-28 mm.

[0014] Furthermore, waterproof glue is provided at the joint between the box body and the aluminum heat exchange tube.

[0015] Furthermore, a steam exhaust fan connected to the interior of the box is provided on the top of the box.

[0016] Furthermore, a plurality of the grooves are threadedly arranged around the outer surface of the aluminum heat exchange tube and extend along the axial direction of the aluminum heat exchange tube, and the inner wall of the aluminum heat exchange tube is configured as a smooth surface.

[0017] Furthermore, a plurality of the grooves are arranged in strips on the outer surface of the aluminum heat exchange tube and extend along the axial direction of the aluminum heat exchange tube, and the inner wall of the aluminum heat exchange tube is arranged to be a smooth surface.

[0018] Beneficial effects of the utility model:

[0019] 1. This device realizes the cooling function based on the working fluid phase change mechanism. Before use, the cooling water is connected through the pipeline interface to make the cooling water flow inside the box. The air guide pipe will guide the hot air from the outside to enter from one end of the aluminum heat exchange tube. The hot air flowing in the aluminum heat exchange tube exchanges heat with the water mist on the surface of the aluminum heat exchange tube to obtain cold air, and then the cold air is discharged from the other end of the aluminum heat exchange tube through the air guide pipe, thereby forming a comfortable cold wind that is significantly lower than the outside atmospheric temperature;

[0020] 2. The device does not require a compressor during the entire cooling process, and can achieve a significant cooling effect by only using the electric energy of the fan. Compared with the existing compressor refrigeration air conditioner, this device can save a lot of energy consumption and use costs;

[0021] 3. The structure of this device is simple and light, and the use cost is low. It not only reduces the occupation of the use space, but also facilitates the placement and use in the closed space. At the same time, this device can be installed in multiple settings to achieve a wide range of cooling coverage, and is suitable for closed spaces such as residential underground parking lots and elevator waiting halls in underground parking lots;

[0022] 4. Since this device does not require the use of refrigerants and compressors, the cold air it provides is healthy and comfortable natural cooling, which effectively reduces the occurrence of air-conditioning disease. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The technical solutions in the embodiments of the present utility model will be described below in conjunction with the accompanying drawings. Example 1

[0030] like Figure 1 and Figure 2As shown, an energy-saving and cooling device for a closed space without a compressor includes a box body 1, wherein a plurality of aluminum heat exchange tubes 2 arranged in parallel are arranged in the box body 1, one end of the aluminum heat exchange tube 2 is arranged on one side outer wall of the box body 1, and the other end of the aluminum heat exchange tube 2 is arranged on the other side outer wall of the box body 1, and a plurality of grooves 3 are arranged on the outer surface of the aluminum heat exchange tube 2, and air guide ducts are arranged on both sides of the box body 1, and the air guide ducts include a ventilation pipe 4 and a fan 5, one end of the ventilation pipe 4 is arranged on the side of the box body 1 and is interconnected with each aluminum heat exchange tube 2, and the fan 5 is arranged at the other end of the ventilation pipe 4, and the other two sides of the box body 1 are provided with pipe interfaces 6 connected to the interior thereof.

[0031] In this embodiment, the device realizes the cooling function based on the phase change mechanism of the working fluid. Before use, the circulating water pipeline is connected by using the pipeline interface 6 to introduce flowing cooling water from the outside into the box body 1. The fan 5 guides the hot air from the outside to enter from one end of the aluminum heat exchange tube 2. The hot air flowing in the aluminum heat exchange tube 2 exchanges heat with the water mist on the surface of the aluminum heat exchange tube 2 to obtain cold air, and then the cold air is discharged from the other end of the aluminum heat exchange tube 2 through the fan 5, thereby forming comfortable cold air that is significantly lower than the outside atmospheric temperature. Among them, due to the continuous flow and replacement of cooling water, the overall temperature of the aluminum heat exchange tube 2 will drop after the heat exchange, ensuring the continuous execution of heat exchange and being able to continuously blow out cold air.

[0032] It should be understood that the device does not require the use of a compressor during the entire cooling and cooling process, and can achieve a significant cooling effect using only a small amount of electric energy. Compared with existing compressor refrigeration and air conditioning, the device can save a lot of energy consumption and use costs. Since no refrigerant and compressor are required, the cold air provided by the device is healthy and comfortable natural cold, which can effectively reduce the occurrence of air-conditioning disease; the device has a simple and light structure and low use cost. It not only reduces the occupancy of the use space, but also is conducive to placement and use in closed spaces. At the same time, the device can be installed in multiple settings to achieve a wide range of cooling coverage, and is suitable for closed spaces such as underground parking lots in residential areas and elevator lobbies in underground parking lots.

[0033] It should be noted that the plurality of grooves 3 can increase the contact area between the aluminum heat exchange tube 2 and the cooling water, thereby enhancing the heat exchange effect of the aluminum heat exchange tube 2 .

[0034] It should be noted that since the hot air flowing in the aluminum heat exchange tube 2 only exchanges heat with the water mist on the surface of the aluminum heat exchange tube 2, the cold air will not be sent to the external environment with moisture, thereby avoiding the problem of water mist directly spraying onto the human body and causing physical discomfort to the user.

[0035] It should be understood that the cooling and cooling of this device is actually related to the ambient temperature and humidity. Please refer to Figure 6 When the device is applied in the actual field, under the environmental condition of less than or equal to 75% humidity, the higher the temperature of the closed space, the greater the temperature difference before and after cooling, and the more obvious the cooling effect achieved by the device.

[0036] It can be understood that the fans 5 on both sides of the box body can be arbitrarily set to air intake and exhaust. Under the guidance of the fans 5, the hot air from the outside can be guided into the aluminum heat exchange tube 2 to perform heat exchange, and then the obtained cold air can be quickly discharged from the aluminum heat exchange tube 2 to the outside, and the outlet direction of the dry cold air can be freely controlled.

[0037] The fans 5 are provided in plurality and are arranged at the other end of the ventilation pipe 4 through the mounting plate 7. The fans 5 are distributed equidistantly. The two sides of the box 1 are each provided with a plurality of fans 5, which is conducive to the collection of hot air from the outside and entering one end of the aluminum heat exchange tube 2. At the same time, when the cold air is discharged, it is also conducive to the cold air spreading to the surroundings, thereby enhancing the cooling effect.

[0038] The other end cover of the ventilation pipe 4 is provided with a filter 8, and the fan 5 is located inside the filter 8. The filter 8 can prevent external debris from being drawn into the aluminum heat exchange tube 2, thereby preventing the aluminum heat exchange tube 2 from being damaged or blocked.

[0039] The inner diameter of the aluminum heat exchange tube 2 is set to 10-28 mm. The inner diameter of the aluminum heat exchange tube 2 is controlled to 10-28 mm to achieve the best air heat exchange effect.

[0040] The joint of the box body 1 and the aluminum heat exchange tube 2 is provided with waterproof glue 9. The waterproof glue 9 can prevent the cooling water flowing inside the box body 2 from flowing out from the joint of the box body 1 and the aluminum heat exchange tube 2, and prevent the cold air from carrying moisture to be discharged outward.

[0041] Several of the grooves 3 are threadedly wrapped around the outer surface of the aluminum heat exchange tube 2 and extend along the axial direction of the aluminum heat exchange tube 2. The inner wall of the aluminum heat exchange tube 2 is set to a smooth surface. The distribution design of the threaded grooves 3 can further increase the contact area between the aluminum heat exchange tube 2 and the cooling water, and under the restriction and guidance of the threaded grooves 3, the cooling water flows around the surface of the aluminum heat exchange tube 2, thereby enhancing the heat exchange effect and improving the cooling efficiency. Example 2

[0042] like Figure 3 , Figure 4 and Figure 5As shown, a plurality of the grooves 3 are arranged in strips on the outer surface of the aluminum heat exchange tube 2 and extend along the axial direction of the aluminum heat exchange tube 2, and the inner wall of the aluminum heat exchange tube 2 is arranged as a smooth surface. The distribution design of the strip grooves 3 can further increase the contact area between the aluminum heat exchange tube 2 and the cooling water, and under the restriction and guidance of the strip grooves 3, the cooling water flows on the surface of the aluminum heat exchange tube 2 for a distance before leaving the aluminum heat exchange tube 2, thereby enhancing the heat exchange effect and improving the cooling efficiency. Example 3

[0043] The top of the box 1 is provided with a steam exhaust fan 10 connected to the interior thereof. Figure 1 and Figure 3 Embodiment 3 adds a steam exhaust fan 10 on the basis of Embodiment 1 and Embodiment 2. During the heat exchange process between hot air and cooling water, part of the cooling water will heat up and form steam. The steam exhaust fan 10 is used to discharge the steam to the outside to ensure that the temperature inside the box 1 drops rapidly and the heat exchange effect is better. It should be understood that when the present device is actually used, it can be selected whether to open a hole on the top of the box 1 and install the steam exhaust fan 10, or to configure a pipe to transport steam to ensure that the external temperature and humidity are not affected by the steam.
