Description

Technical Field

[0001] This utility model relates to the field of condenser technology, and specifically discloses an evaporative condenser. Background Technology

[0002] Evaporative condensers are the main heat exchange equipment in refrigeration systems. Their working principle is as follows: the superheated and high-pressure refrigerant gas discharged from the compressor in the refrigeration system passes through the condenser coils in the evaporative condenser, allowing the high-temperature gaseous refrigerant to exchange heat with the sprayed water and air outside the coils.

[0003] In existing evaporative condensers, most of the water that falls onto the condenser coils drips directly from the coils. The water has a short contact time with the condenser coils, and the condenser coils cannot fully exchange heat with the water, resulting in a reduced heat exchange efficiency. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, this application aims to provide an evaporative condenser, including a housing, a first fresh air inlet disposed on the top of the housing, a second fresh air inlet disposed on one side of the housing, an L-shaped pipe disposed inside one side of the housing, a gaseous refrigerant inlet, a liquid refrigerant inlet and a liquid extraction pipe disposed on the outer side of the top of the L-shaped pipe, and a water pump connected between the L-shaped pipe and the liquid extraction pipe. A first filter screen located above the first fresh air inlet is installed on the inner side of the top of the housing, and a second filter screen located outside the second fresh air inlet is installed on the inner side of one side of the housing. A dustproof mechanism is installed on one side of the top of the housing. An exhaust pipe with a hot air outlet running through it is disposed on the side of the housing away from the gaseous refrigerant inlet, and a fan is fixedly installed on the outer side of the exhaust pipe.

[0005] The gaseous refrigerant inlet extends to the outer side of one end inside the box and is connected to a first connecting pipe. The liquid refrigerant inlet extends to the outer side of one end inside the box and is connected to a second connecting pipe. Both the first and second connecting pipes are connected to condenser pipes. The condenser pipes are staggered in adjacent upper and lower layers, and each layer of condenser pipes is connected to each other through an adapter. A water collector is fixedly installed on the inner side of the box.

[0006] Preferably, the top of the housing is provided with a baffle wall located above the first filter screen, and a protective cover located outside the baffle wall is hinged to one side of the top of the housing.

[0007] Preferably, the dustproof mechanism includes a baffle that is fitted inside the top of the box and has a hot air outlet running through it, and an electric telescopic rod that is fixedly installed on the top of the box. The top of the baffle is provided with a connecting plate, and a fixing pin that is fixedly fitted inside the bottom of the electric telescopic rod is movably connected to the inside of the connecting plate.

[0008] Preferably, the outer side of the condenser pipe is fixedly fitted with wavy, equally spaced heat-conducting fins.

[0009] Preferably, the inside of the housing is fixedly fitted with magnets located outside the first fresh air inlet and the second fresh air inlet, and iron pillars are fixedly fitted inside both the first filter and the second filter.

[0010] Preferably, the top of the baffle is provided with a pressure plate located outside the connecting plate, and the inner side of the top of the box is fitted with a sealing gasket located below the pressure plate and outside the baffle.

[0011] The advantages of this utility model are as follows:

[0012] 1. This evaporative condenser, by staggering the condenser coils in adjacent upper and lower layers, allows water sprayed from inside the nozzle to drip down layer by layer along the surface of each condenser coil, thereby increasing the contact time between the water and the condenser coils. Furthermore, by setting wavy heat-conducting fins on the outside of the condenser coils, the contact area with the water can be increased, allowing the condenser coils to fully exchange heat with the water, thus improving the heat exchange effect of the condenser.

[0013] 2. This evaporative condenser, driven by an electric telescopic rod, can cause the baffle and the hot air outlet inside the exhaust pipe to be misaligned, while blocking the exhaust pipe. This prevents external dust from entering the interior of the housing from the exhaust pipe when the condenser is not working, thus ensuring that the water inside the housing does not easily become dirty, allowing the water inside the housing to be circulated and reused.

[0023] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0024] The accompanying drawings in this utility model embodiment: different types of cross-sectional lines in the drawings are not labeled according to national standards, nor do they specify the material requirements of the components. They are used to distinguish the cross-sectional views of the components in the drawings.

[0025] Please see Figure 1-7An evaporative condenser includes a housing 1, a first fresh air inlet 2 located at the top of the housing 1, a second fresh air inlet 3 located on one side of the housing 1, an L-shaped pipe 4 located inside one side of the housing 1, a gaseous refrigerant inlet 5, a liquid refrigerant inlet 6, and a liquid extraction pipe 7, as well as an L-shaped pipe 4 located outside the top of the L-shaped pipe 4 and a water pump 9 connecting the L-shaped pipe 4 and the liquid extraction pipe 7. Driven by the water pump 9, water from the bottom of the inner side of the housing 1 is transported through the liquid extraction pipe 7 to the interior of the L-shaped pipe 4. Water inside the L-shaped pipe 4 is sprayed out through a nozzle 8, forming water droplets that gradually fall onto the surface of the condenser coil 17. A first filter screen 10 is installed on the inner side of the top of the housing 1, above the first fresh air inlet 2. The first filter screen... The filter 10 can filter the air entering the box 1 from the first fresh air inlet 2, and a second filter 11 located outside the second fresh air inlet 3 is installed on the inner side of one side of the box 1. The second filter 11 can filter the air entering the box 1 from the second fresh air inlet 3. A dustproof mechanism 12 is installed on one side of the top of the box 1. An exhaust pipe 13 with a hot air outlet is provided on the side of the box 1 away from the gaseous refrigerant inlet 5. A fan 14 is fixedly installed on the outer side of the exhaust pipe 13. Driven by the fan 14, the hot air generated inside the box 1 can be discharged to the outside through the exhaust pipe 13. The exhaust pipe 13 is set horizontally so that external dust is not easy to enter the inner side of the exhaust pipe 13.

[0026] A gaseous refrigerant inlet 5 extends to the outer side of one end of the inner side of the housing 1 and is connected to a first connecting pipe 15. A liquid refrigerant inlet 6 extends to the outer side of one end of the inner side of the housing 1 and is connected to a second connecting pipe 16. Both the first connecting pipe 15 and the second connecting pipe 16 are connected to condenser pipes 17. The condenser pipes 17 are staggered in adjacent upper and lower layers, and each layer of condenser pipes 17 is connected to each other through an adapter 18. A water collector 19 is fixedly installed on the inner side of the housing 1. The water collector 19 can separate the moisture in the water and air, thereby reducing the loss of moisture.

[0027] The top of the housing 1 is provided with a baffle 20 above the first filter screen 10, and a protective cover 21 is hinged to one side of the top of the housing 1 outside the baffle 20. The baffle 20 and the protective cover 21 work together to shield and protect the first filter screen 10, preventing external dust from falling onto the surface of the first filter screen 10. There is a gap between the baffle 20 and the protective cover 21, so that external air can enter the interior of the housing 1 through the first fresh air inlet 2 under the drive of the fan 14.

[0028] The dustproof mechanism 12 includes a baffle 121 fitted inside the top of the housing 1 and having a hot air outlet running through it, and an electric telescopic rod 122 fixedly installed on the top of the housing 1. A connecting plate 123 is provided on the top of the baffle 121. A fixing pin 124 fixedly fitted inside the bottom of the electric telescopic rod 122 is movably connected to the connecting plate 123. Driven by the electric telescopic rod 122, the baffle 121 can be moved upward, thus misaligning the baffle 121 with the hot air outlet inside the exhaust pipe 13. Therefore, when the condenser is not working, the baffle 121 can block and seal the exhaust pipe 13, preventing external dust from entering the interior of the housing 1 through the exhaust pipe 13.

[0029] The condenser coil 17 is fixedly fitted with wavy heat-conducting fins 22 that are evenly spaced. The heat-conducting fins 22 can increase the contact area between the condenser coil 17 and the water droplets, so that the condenser coil can fully contact and exchange heat with the water sprayed from the nozzle 8.

[0030] The housing 1 has a magnet 23 fixedly installed inside, located outside the first fresh air inlet 2 and the second fresh air inlet 3. The first filter screen 10 and the second filter screen 11 are both fixedly installed inside, and the magnet 23 and the iron column 24 are used to install the first filter screen 10 and the second filter screen 11 on the inside of the housing 1 by magnetic adsorption, which makes it convenient to disassemble and clean the first filter screen 10 and the second filter screen 11.

[0031] The top of the baffle 121 is provided with a pressure plate 25 located outside the connecting plate 123. The inner side of the top of the box 1 is fitted with a sealing gasket 26 located below the pressure plate 25 and outside the baffle 121. The pressure plate 25 can squeeze the sealing gasket 26 and seal the gap between the baffle 121 and the box 1. Then, driven by the fan 14, the air inside the box 1 can be drawn through the exhaust pipe 13, so that the outside air can effectively enter the inside of the box 1 through the first fresh air inlet 2 and the second fresh air inlet 3.

[0032] When the condenser is working, the water pump 9 and the fan 14 are started. Driven by the water pump 9, water inside the housing 1 is transported through the L-shaped pipe 4 to the inside of the nozzle 8 and sprayed out. The sprayed water droplets fall onto the surface of the condenser coil 17, exchanging heat and cooling the condenser coil 17. Driven by the fan 14, air is drawn from the inside of the housing 1. Outside air is filtered through the first filter screen 10 and the second filter screen 11 and then enters the inside of the housing 1 through the first fresh air inlet 2 and the second fresh air inlet 3, cooling the inside of the housing 1. At this time, gaseous refrigerant is transported from the gaseous refrigerant inlet 5 to the inside of the condenser coil 17. The gaseous refrigerant exchanges heat with the condenser coil 17. The refrigerant gradually turns into liquid refrigerant, which is then discharged to the outside through the liquid refrigerant inlet 6. During this process, the heat absorbed by the condenser pipe 17 heats and evaporates the moisture on its surface to form hot air. As the air inside the first fresh air inlet 2 flows, the hot air is transported to the lower inside of the housing 1. The hot air then follows the air entering from the second fresh air inlet 3 and is transported in the opposite direction to the water collector 19. The water collector 19 separates the moisture contained in the air. The hot air after water and air separation is discharged to the outside through the hot air outlet inside the baffle 121 and the exhaust pipe 13. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed.
