AI Technical Summary
Traditional defrosting methods are energy-intensive, and uneven frost thickness leads to excessively long defrosting times. Furthermore, once the frost layer freezes, the air ducts are easily blocked, affecting the operation of the fan. Existing thermal fluorine defrosting technology also suffers from secondary accumulation and water condensation problems under long-term use.
A hot-fluorine defrosting air cooler was designed. High-temperature and high-pressure hot fluorine enters the diversion and folding elastic capsule, pushing the second downward heat-conducting plate to move down and contact the radiator and the outer shell. Combined with the electromagnet adsorbing the heat-conducting block, heat conduction and frost compression are accelerated. The defrosting speed is accelerated by using micro graphite heat-conducting blocks and hydrophobic film.
It effectively shortens defrosting time, avoids air duct blockage, reduces water residue, ensures normal operation of the fan, and improves defrosting efficiency and safety.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of air cooler technology, specifically an air cooler for hot fluorine defrosting. Background Technology
[0002] In low-temperature refrigeration systems, evaporators, acting as evaporators, achieve efficient heat exchange through forced air circulation. However, frost easily forms on their surfaces during operation, leading to duct blockage, decreased heat exchange efficiency, and increased energy consumption. Traditional defrosting methods (such as electric defrosting and water defrosting) suffer from high energy consumption, large temperature fluctuations, safety hazards, and poor adaptability to low-temperature environments. To address these issues, hot-fluid defrosting technology has emerged. Its core principle is to utilize the high-temperature, high-pressure gaseous refrigerant discharged from the compressor. By switching the refrigerant flow direction through a solenoid valve or four-way valve, the high-temperature gas is directly introduced into the evaporator of the evaporator, where the heat released from refrigerant condensation melts the frost layer.
[0003] When using the heat released by the refrigerant to melt the frost layer, the melting time depends on the thickness of the frost layer; the thicker the frost layer, the longer it takes to melt. However, under long-term use, the direction and position of the frost layer are uncertain. After a long period of use, a thick layer of frost may form between the outside of the radiator and the outer casing, but the air duct is not yet blocked. Frost continues to accumulate inside, and once the air duct is blocked, the frost layer has already frozen and become quite thick. At this point, using hot refrigerant again will result in an excessively long defrosting time. The long processing time will affect the operation of the fan. Furthermore, when the existing radiator is tightly fitted to the outer casing, some water will remain between the radiator and the outer casing. When the fan is restarted, this water will re-condense, causing secondary frost accumulation, which can easily lead to secondary blockage of the air duct in a short period of time. Therefore, a hot refrigerant defrosting fan is proposed. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-7 This utility model provides a technical solution:
[0024] A hot-fluorine defrosting air cooler includes: a fixed outer shell 1, an upper cover 2 snapped onto the fixed outer shell 1, multiple radiators 3 fixedly connected inside the fixed outer shell 1, the multiple radiators 3 being in contact with each other, and each of the multiple radiators 3 being interconnected by a guide pipe 4, the distance between the two sides of the radiators 3 and the inner wall of the fixed outer shell 1 being not less than 1.5 cm, two folded elastic bladders 10 fixedly connected below the radiators 3, the outside of the folded elastic bladders 10 being connected to a diversion elastic bladder 8, the air inlet of the diversion elastic bladder 8 being connected to a valve 7, the valve 7 being connected to a hot-fluorine air outlet pipe, a second downward pressure heat conduction plate 11 fixedly connected to the side of the folded elastic bladder 10 away from the radiators 3, one of the radiators 3 being connected to an inlet pipe 5, and the other radiator 3 being connected to an outlet pipe 6.
[0025] Specifically, during use, by connecting the inlet pipe 5 to the hot refrigerant inlet channel and the outlet pipe 6 to the hot refrigerant outlet channel, the high-temperature, high-pressure hot refrigerant, after entering the inlet pipe 5, is continuously transported to the radiator 3 connected to the inlet pipe 5. The hot refrigerant entering the radiator 3 connected to the inlet pipe 5 is then transferred to the remaining radiators 3 via the guide pipe 4. The radiators 3 then conduct the heat of the high-temperature, high-pressure hot refrigerant to the outside for defrosting. Once a thick layer of frost has formed on the outside of the radiators 3 and the inside of the fixed casing 1, the hot refrigerant inlet pipe can be connected to valve 7 to release the high-temperature, high-pressure... The hot fluorine is delivered to the interior of the splitting elastic bladder 8 and the folded elastic bladder 10. After the hot fluorine under high temperature and pressure enters the interior of the folded elastic bladder 10, the hot fluorine gas under high temperature and pressure will expand the folded elastic bladder 10. After the folded elastic bladder 10 is expanded, it will cause the second downward pressure heat conduction plate 11 to move downward. The downward moving second downward pressure heat conduction plate 11 will gradually contact the outer wall of the cold radiator 3 and the inner wall of the fixed shell 1. The heat in the hot fluorine will be gradually conducted to the frost surface through the second downward pressure heat conduction plate 11, causing the frost to melt and squeeze, and the overall process will further accelerate the peeling of the frost.
[0026] like Figures 1-2 As shown, multiple fans 12 are installed on the radiator 3, and the air intake of the fan 12 is connected to the fixed housing 1.
[0027] Specifically, during the peeling of frost, the gas can be discharged upward through the fan 12. The steam generated when melting frost floats upward, and the fan 12 located on the upper cover 2 can discharge the steam inside the fixed outer casing 1 more quickly.
[0028] like Figure 3 As shown, a first downward heat-conducting plate 9 is fixedly connected to the lower part of the diversion elastic bladder 8. The first downward heat-conducting plate 9 is located between the inlet pipe 5 and the outlet pipe 6.
[0029] Specifically, when the gas entering the folded elastic bladder 10 expands, the diversion elastic bladder 8 will also expand. When the diversion elastic bladder 8 expands, the frost between the inlet pipe 5 and the outlet pipe 6 can be scraped off.
[0030] like Figures 3-7 As shown, two inclined spade plates 13 are fixedly connected to the lower part of the second downward heat conduction plate 11. The inclined spade plates 13 are attached to the outer wall of the cold radiator 3 and the inner side wall of the fixed housing 1.
[0031] Specifically, during the downward movement, the second downward heat-conducting plate 11 will work with the outwardly protruding inclined spade 13 to quickly peel the frost off from the inner wall of the fixed outer shell 1 and the outer wall of the radiator 3, further strengthening the adhesion and connection of the second downward heat-conducting plate 11 to the fixed outer shell 1 and the radiator 3.
[0032] like Figures 3-7 As shown, the second pressing heat-conducting plate 11 has two iron heat-conducting blocks 14 integrally formed inside, and two electromagnets 15 are fixedly connected to the bottom of the fixed housing 1. Multiple support feet 16 are fixedly connected to the bottom of the fixed housing 1, and the support feet 16 are located on one side of the electromagnets 15.
[0033] Specifically, when the folded elastic bladder 10 is continuously filled with hot fluorine at high temperature and high pressure, the folded elastic bladder 10 will expand and push the second downward heat-conducting plate 11 to move downward. At the same time, during the downward movement of the second downward heat-conducting plate 11, the electromagnet 15 can be activated to attract the iron heat-conducting block 14. During the process of the electromagnet 15 attracting the iron heat-conducting block 14, the downward movement speed of the second downward heat-conducting plate 11 can be accelerated, thereby further strengthening the squeezing force on the frost and further accelerating the elimination and peeling speed of the frost.
[0034] like Figure 5 As shown, guide grooves 17 are provided on both sides of the inner wall of the fixed outer shell 1, and the second pressing heat conduction plate 11 is slidably connected to the inside of the guide grooves 17.
[0035] Specifically, during the downward movement of the second pressing heat-conducting plate 11, the second pressing heat-conducting plate 11 will slide inside the guide groove 17, which can be used to guide the downward movement of the second pressing heat-conducting plate 11.
[0036] like Figure 6 As shown, the interior of the folded elastic capsule 10 is integrally formed with multiple micro graphite heat-conducting blocks 18.
[0037] Specifically, during the expansion of the folded elastic bladder 10, it not only drives the second downward heat-conducting plate 11 to move downward, but also comes into contact with the fixed outer shell 1, the inner wall, and the outer wall of the radiator 3 during the expansion process. When this contact occurs, the micro graphite heat-conducting block 18 located inside the folded elastic bladder 10 conducts the heat inside the folded elastic bladder 10 to the contacted outer wall of the radiator 3 and the inner wall of the fixed outer shell 1, thereby further conducting the heat of the hot fluorine to the frost and further accelerating the defrosting speed. In addition, a hydrophobic film is coated on the outside of the folded elastic bladder 10, which can further reduce the water residue on the outside of the folded elastic bladder 10 and avoid the phenomenon that the folded elastic bladder 10 is continuously frozen in the folded state. When the folded elastic bladder 10 springs back to its original state, it will also squeeze out the water from the outside, reducing the phenomenon of water remaining between the outer wall of the radiator 3 and the inner wall of the fixed outer shell 1.
[0038] Based on the above technical solution, the working steps of this solution are summarized as follows: During the normal defrosting stage, the inlet pipe 5 is connected to the hot refrigerant inlet channel, and the outlet pipe 6 is connected to the hot refrigerant outlet channel. The high-temperature and high-pressure hot refrigerant enters the connected radiator 3 through the inlet pipe 5, and is then transferred to other radiators 3 through the guide pipe 4. The radiators 3 then conduct heat to the outside for defrosting. At the same time, the fan 12 installed on the radiator 3 has its air inlet connected to the fixed housing 1, which can discharge the upward floating steam generated by melting frost. During the deep defrosting stage, when the frost on the outside of the radiator 3 and the inside of the fixed housing 1 is thick, the hot refrigerant inlet pipe is connected to the valve 7. The high-temperature and high-pressure hot refrigerant enters the diversion elastic bladder 8 and the folding elastic bladder 10, causing them to expand and push the second downward pressure heat conduction plate 11 down along the guide groove 17 on the inner side wall of the fixed housing 1. The second downward pressure heat conduction plate 11 gradually contacts the outer wall of the radiator 3 and the inner wall of the fixed housing 1. The heat from the hot refrigerant is transferred through the second downward pressure heat conduction plate 11. The heat is conducted to the frost surface, accelerating the melting of the frost; the inclined scraper 13 below the second downward pressure heat conduction plate 11 adheres to the outer wall of the radiator 3 and the inner wall of the fixed shell 1, and works together to quickly peel off the frost during the downward movement, enhancing the adhesion; at the same time, when the diversion elastic bladder 8 expands, the first downward pressure heat conduction plate 9 below it can scrape off the frost between the inlet pipe 5 and the outlet pipe 6; and, the electromagnet 15 at the bottom of the fixed shell 1 is activated to attract the iron heat conduction block 14 in the second downward pressure heat conduction plate 11, accelerate the downward movement speed of the second downward pressure heat conduction plate 11, enhance the squeezing force on the frost, and accelerate the elimination of the frost; in addition, when the micro graphite heat conduction block 18 in the folded elastic bladder 10 expands and adheres to the inner wall of the fixed shell 1 and the outer wall of the radiator 3, it conducts heat to the frost, accelerates defrosting, and its external hydrophobic film can reduce water residue, prevent the folded elastic bladder 10 from being continuously frozen, and when it rebounds, it can also squeeze out the external water flow, reducing the residue between the outer wall of the radiator 3 and the inner wall of the fixed shell 1.

Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
