Description

Technical Field

[0001] This utility model relates to the field of air conditioning and refrigeration equipment technology, specifically an air conditioning evaporator with a condensation reflux mechanism. Background Technology

[0002] The evaporator is the core heat exchange component of an air conditioning refrigeration system, and its performance directly affects the cooling effect and energy consumption level of the air conditioner. During the operation of the air conditioner, when the refrigerant flows in the evaporator tubes, it is affected by factors such as flow velocity, heat exchange area, and airflow distribution, which can easily lead to some liquid refrigerant flowing out of the evaporator before it has fully evaporated.

[0003] Existing air conditioner evaporators lack an effective condensation reflux structure. Unevaporated liquid refrigerant directly enters the compressor, which not only fails to participate in heat exchange but may also cause liquid slugging in the compressor, shortening the equipment's service life. Moreover, the heat exchange tubes are mostly straight tubes or simple U-shaped tubes, resulting in a short residence time of the refrigerant inside the tubes, insufficient evaporation, and low heat exchange efficiency. Therefore, those skilled in the art have provided an air conditioner evaporator with a condensation reflux mechanism to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide an air conditioner evaporator with a condensation reflux mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An air conditioner evaporator with a condensation reflux mechanism includes a housing and a liquid pump. The inner wall of the housing is connected to equidistantly arranged connecting plates. The front sides of multiple connecting plates are connected to two sets of heat dissipation fins. The inner walls of the two sets of heat dissipation fins are connected to a conduit. The outer surface of the conduit is connected to two reflux pipes. One end of one of the reflux pipes is connected to a liquid collection tank. The output end of the liquid pump is connected to a liquid guide pipe. The end of the liquid guide pipe away from the liquid pump is connected to the liquid collection tank. A cooler is installed on the inner bottom wall of the liquid collection tank. The front and back sides of the liquid collection tank are connected to equidistantly arranged heat dissipation plates.

[0006] As a further improvement of this utility model: both ends of the conduit penetrate the shell, and a liquid level sensor is installed on the inner bottom wall of the liquid collection tank.

[0007] As a further improvement of this utility model: two ventilation windows are provided on the back of the housing, and the inner walls of the two ventilation windows are connected with dustproof nets.

[0008] As a further improvement of this utility model: a cover plate is installed on the front of the housing by screws, and two mounting plates are connected to both the left and right sides of the housing.

[0009] As a further improvement of this utility model: each of the mounting plates in the group has mounting holes on one side that is close to each other, and each mounting hole has mounting screws inside.

[0010] As a further improvement of this utility model: two reinforcing plates are connected to both the left and right sides of the housing, and the side of each set of reinforcing plates that is far apart from each other is connected to the mounting plate.

[0011] As a further improvement of this utility model: the outer surface of the conduit is connected to a circular tube, and a pressure gauge is installed at one end of the circular tube.

[0012] As a further improvement of this utility model: each of the heat dissipation fins is made of aluminum, and the input end of the infusion pump is connected to one of the return pipes.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This air conditioner evaporator with a condensation reflux mechanism guides the condensate generated on the outer surface of the duct to a collection tank via a reflux pipe. The pump then returns the condensate to the system via a liquid guide pipe, achieving condensate recycling. The low-temperature characteristics of the condensate help reduce the temperature of the duct and heat dissipation fins, reducing heat loss. At the same time, the aluminum heat dissipation fins have high thermal conductivity, further enhancing the heat exchange effect and improving the overall heat exchange efficiency of the evaporator. The ventilation window, combined with a dustproof screen, can prevent dust from entering the casing and avoid dust accumulation affecting heat dissipation. The sealed connection between the cover and the casing protects the internal components from external environmental corrosion. Attached Figure Description

[0016] Please see Figures 1-5 In this embodiment of the present invention, an air conditioner evaporator with a condensation reflux mechanism includes a housing 1 and a liquid pump 10. The inner wall of the housing 1 is connected to connecting plates 2 arranged at equal intervals. The front sides of multiple connecting plates 2 are connected to two sets of heat dissipation fins 3. The inner walls of the two sets of heat dissipation fins 3 are connected to a conduit 4. The outer surface of the conduit 4 is connected to two reflux pipes 9. One end of one reflux pipe 9 is connected to a liquid collection tank 11. The output end of the liquid pump 10 is connected to a liquid guide pipe 18. The end of the liquid guide pipe 18 away from the liquid pump 10 is connected to the liquid collection tank 11. A cooler 19 is installed on the inner bottom wall of the liquid collection tank 11. The front and back sides of the liquid collection tank 11 are connected to heat dissipation plates 20 arranged at equal intervals. The low temperature characteristics of condensate help to reduce the temperature of the conduit 4 and the heat dissipation fins 3, reducing the waste of cooling capacity. The aluminum heat dissipation fins 3 have excellent thermal conductivity and, together with the connecting plates 2 for stable support, can fully expand the heat exchange area, significantly improve the overall heat exchange efficiency of the evaporator, and reduce the energy consumption of the air conditioner.

[0017] Both ends of the conduit 4 penetrate the housing 1. A liquid level sensor 8 is installed on the inner bottom wall of the collection tank 11. Two ventilation windows 5 are opened on the back of the housing 1. Dustproof nets 6 are connected to the inner walls of the two ventilation windows 5. A cover plate 7 is installed on the front of the housing 1 by screws. Two mounting plates 12 are connected to the left and right sides of the housing 1. This not only allows people to disassemble and install the cover plate 7, but also makes the dust removal effect of the equipment better.

[0018] Each set of mounting plates 12 has mounting holes 13 on the side facing each other, and each mounting hole 13 has a mounting screw 14 inside. The left and right sides of the housing 1 are connected to two reinforcing plates 15. The side facing away from each other of each set of reinforcing plates 15 is connected to the mounting plate 12. The outer surface of the conduit 4 is connected to a round tube 16, and a pressure gauge 17 is installed at one end of the round tube 16. Each heat dissipation fin 3 is made of aluminum. The input end of the infusion pump 10 is connected to one of the return pipes 9. This not only greatly increases the strength of the mounting plate 12, but also makes the heat dissipation effect of the equipment better, thereby greatly increasing the practicality of the equipment.

[0019] The working principle of this utility model is as follows: First, the refrigerant flows through the conduit 4 that passes through the shell 1. The two sets of aluminum heat dissipation fins 3 fixed by the connecting plate 2 expand the heat exchange area and accelerate the heat exchange between the refrigerant and the air inside the shell 1. During the heat exchange process, the condensate generated on the outer surface of the conduit 4 is guided through the two return pipes 9 connected to its outer surface. One of the return pipes 9 transports the condensate to the collection tank 11 to complete the collection of condensate.

[0020] Then, the liquid level sensor 8 on the bottom wall of the collection tank 11 monitors the amount of condensate in real time. When the amount of water reaches the set value, the infusion pump 10 is started. The infusion pump 10 draws condensate through the return pipe 9 at the input end and sends the condensate back to the collection tank 11 through the liquid guide pipe 18 at the output end, realizing the recycling of condensate. This helps to reduce the temperature of the conduit 4 and the heat dissipation fins 3 and improve the heat exchange efficiency. The cooler 19 and the heat dissipation plate 20 can cool the return liquid inside the collection tank 11.

[0021] Meanwhile, the two ventilation windows 5 on the back of the housing 1 ensure air circulation, and the dustproof net 6 on the inner wall prevents dust from entering; the round tube 16 on the outer surface of the conduit 4 is connected to the pressure gauge 17 to monitor the pressure inside the conduit 4 in real time and avoid abnormal pressure.
