Description

Technical Field

[0001] This application relates to the field of heat exchanger technology, and in particular to a novel air conditioning heat exchanger. Background Technology

[0002] In the field of air conditioning systems, heat exchangers are core components, and their performance is directly related to the overall efficiency and energy consumption of the air conditioning system. With the continuous advancement of air conditioning technology and the increasing demands of people for the energy efficiency ratio and operational stability of air conditioning systems, the performance of heat exchangers is crucial.

[0003] Traditional air conditioning heat exchangers use smooth tube walls or simple fins, resulting in limited heat transfer efficiency. Especially under high-pressure working fluids, they are prone to forming a thermal resistance layer, leading to low heat exchange efficiency and high energy consumption. This not only increases operating costs but also does not conform to the current development trend of energy conservation and emission reduction.

[0004] Therefore, this application provides a novel air conditioning heat exchanger. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a novel air conditioning heat exchanger that overcomes these deficiencies. It aims to solve the problem that traditional air conditioning heat exchangers, which use smooth tube walls or simple fins, have limited heat transfer efficiency. In particular, they are prone to forming a thermal resistance layer under high-pressure working fluids, resulting in low heat exchange efficiency and high energy consumption. This not only increases operating costs but also does not conform to the current development trend of energy conservation and emission reduction.

[0006] To achieve the above objectives, this application provides the following technical solution: A novel air conditioning heat exchanger includes a housing, inside which a heat exchange tube mechanism is provided. The heat exchange tube mechanism includes several sets of vertical pipes, which are connected by bends. The sets of vertical pipes are interconnected through the bends. The top of the vertical pipe near the inlet end of the housing is connected to an inlet pipe, and the top of the vertical pipe near the outlet end of the housing is connected to an outlet pipe. Both the inlet and outlet pipes extend to the outside of the housing. The outer surface of each set of vertical pipes is provided with a reinforcing mechanism, which includes several sets of ribs. The ribs are spirally fixed to the outer wall of the vertical pipes, and the ribs have an irregular shape design.

[0007] By adopting the above technical solution, high-pressure refrigerant enters the outer shell through the outlet pipe. Since several sets of risers are connected by several sets of bends, the high-pressure refrigerant then enters several sets of risers. When flowing through several sets of risers, the effective heat exchange area is increased by the strengthening mechanism. Heat is transferred through the tube wall of the heat exchange tube mechanism and the strengthening mechanism. Finally, the refrigerant flows out from the outlet pipe. The fins are designed with an irregular shape to generate secondary flow, enhance the heat disturbance of the hot and cold medium, destroy the thermal resistance layer, improve the heat exchange efficiency, and reduce energy consumption.

[0008] As a preferred technical solution of this application, a filtration mechanism is provided at the end of the inlet pipe away from the riser. The filtration mechanism includes a filter shell, and connectors are provided on both sides of the filter shell. The filter shell is connected to the inlet pipe through the connectors. A coarse filter layer and a fine filter layer are fixedly installed inside the filter shell, and the fine filter layer is located between the coarse filter layer and the inlet pipe.

[0009] By adopting the above technical solution, the high-pressure refrigerant passes through the filter shell before entering the heat exchange tube. Through the dual filtration of the coarse and fine filter layers, the cleanliness of the high-pressure refrigerant is improved, the generation of scale in the heat exchange tube mechanism is reduced, and the maintenance requirements of the heat exchange tube mechanism are greatly reduced.

[0010] As a preferred technical solution of this application, a temperature sensor and a pressure sensor are installed on one side of both the inlet pipe and the outlet pipe.

[0011] By adopting the above technical solution, the pressure and temperature of the refrigerant in the inlet and outlet pipes can be monitored in real time through pressure and temperature sensors, providing data support when the device malfunctions, thus improving its practicality during use.

[0012] As a preferred technical solution of this application, a controller is fixedly installed inside the heat exchange tube mechanism, and both the temperature sensor and the pressure sensor are electrically connected to the controller.

[0013] By adopting the above technical solution, the controller feeds back the data from the pressure sensor and temperature sensor to the mobile terminal, making it convenient for staff to check the operating status of the device at any time.

[0014] As a preferred technical solution of this application, the outer surface of the rib is coated with a superhydrophobic self-cleaning coating.

[0015] By adopting the above technical solution, the fins reduce dust and dirt on the fin surface, thus ensuring the heat dissipation effect of the fins.

[0016] As a preferred technical solution of this application, a sealing layer is fixedly installed at the connection between the inlet pipe and the outlet pipe and the outer shell, and an installation plate is fixedly installed on one side of the sealing layer. Several sets of fixing bolts are installed at the connection between the installation plate and the outer shell.

[0017] By adopting the above technical solution, the sealing layer and pressure sensor are securely installed using mounting plates and fixing bolts, thereby improving the sealing performance of the housing.

[0018] As a preferred technical solution of this application, a connecting flange is installed at the ends of the inlet pipe and the outlet pipe that are far apart from each other.

[0019] By adopting the above technical solution, the sealing performance of the inlet and outlet pipes is improved when connected to the external pipeline via connecting flanges.

[0020] The beneficial effects of this application are:

[0021] 1. High-pressure refrigerant enters the outer casing through the outlet pipe. Since several sets of risers are connected by several sets of bends, the high-pressure refrigerant then enters several sets of risers. When flowing through several sets of risers, the effective heat exchange area is increased by the strengthening mechanism. Heat is transferred through the tube wall of the heat exchange tube mechanism and the strengthening mechanism. Finally, the refrigerant flows out from the outlet pipe. The fins are designed with an irregular shape to generate secondary flow, enhance the heat disturbance of the hot and cold medium, destroy the thermal resistance layer, improve the heat exchange efficiency, and reduce energy consumption.

[0022] 2. Before entering the heat exchange tubes, the high-pressure refrigerant passes through the filter shell and undergoes dual filtration through coarse and fine filter layers, which improves the cleanliness of the high-pressure refrigerant, reduces the formation of scale in the heat exchange tube mechanism, and greatly reduces the maintenance requirements of the heat exchange tube mechanism.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Reference Figure 1-4A novel air conditioning heat exchanger includes a housing 1. A heat exchange tube mechanism 2 is disposed inside the housing 1. The heat exchange tube mechanism 2 includes several sets of risers 201, with bends 202 connecting the sets of risers 201. The sets of risers 201 are interconnected through the bends 202. An inlet pipe 203 is connected to the top of the riser 201 near the inlet end of the housing 1, and an outlet pipe 204 is connected to the top of the riser 201 near the outlet end of the housing 1. Both the inlet pipe 203 and the outlet pipe 204 extend to the outside of the housing 1. A reinforcing mechanism 3 is disposed on the outer surface of each set of risers 201. The reinforcing mechanism 3 includes several sets of ribs 301, which are spirally fixed to the outer wall of the risers 201 and have an irregular shape. A temperature sensor 7 and a pressure sensor 5 are installed on one side of both the inlet pipe 203 and the outlet pipe 204.

[0030] High-pressure refrigerant enters the outer casing 1 through outlet pipe 204. Since several sets of risers 201 are connected by several sets of bends 202, the high-pressure refrigerant then enters several sets of risers 201. As it flows through several sets of risers 201, the effective heat exchange area is increased by the strengthening mechanism 3. Heat is transferred through the tube wall of the heat exchange tube mechanism 2 and the strengthening mechanism 3. Finally, the refrigerant flows out from outlet pipe 204. The fins 301 are designed with an irregular shape to generate secondary flow, enhance the heat disturbance of the hot and cold medium, destroy the thermal resistance layer, improve heat exchange efficiency, and reduce energy consumption. The pressure sensor 5 and temperature sensor 7 can monitor the pressure and temperature of the refrigerant in inlet pipe 203 and outlet pipe 204 in real time, providing data support when the device malfunctions, thus improving its practicality during use.

[0031] Reference Figure 1-3 A filter mechanism 4 is provided at the end of the inlet pipe 203 away from the riser pipe 201. The filter mechanism 4 includes a filter shell 401. Connectors 402 are provided on both sides of the filter shell 401. The filter shell 401 is connected to the inlet pipe 203 through the connectors 402. A coarse filter layer 403 and a fine filter layer 404 are fixedly installed inside the filter shell 401, and the fine filter layer 404 is located between the coarse filter layer 403 and the inlet pipe 203. A controller 6 is fixedly installed inside the heat exchange tube mechanism 2. The temperature sensor 7 and the pressure sensor 5 are electrically connected to the controller 6.

[0032] Before the high-pressure refrigerant enters the inlet pipe 203, it first passes through the filter shell 401. Through the dual filtration of the coarse filter layer 403 and the fine filter layer 404, the cleanliness of the high-pressure refrigerant is improved, the formation of scale in the heat exchange tube mechanism 2 is reduced, and the maintenance requirements of the heat exchange tube mechanism 2 are greatly reduced. The controller 6 feeds back the data of the pressure sensor 5 and the temperature sensor 7 to the mobile terminal, so that the staff can check the operating status of the device at any time.

[0033] Reference Figure 2-4The outer surface of the fin 301 is coated with a superhydrophobic self-cleaning coating; a connecting flange 11 is installed at the far end of the inlet pipe 203 and the outlet pipe 204; the fin 301 reduces dust and dirt on its surface, ensuring the heat dissipation effect of the fin 301; the connection between the inlet pipe 203 and the outlet pipe 204 and the external pipe through the connecting flange 11 improves the sealing performance when the inlet pipe 203 and the outlet pipe 204 are connected to the external pipe.

[0034] Reference Figure 1-3 A sealing layer 8 is fixedly installed at the connection between the inlet pipe 203 and the outlet pipe 204 and the outer shell 1. A mounting plate 9 is fixedly installed on one side of the sealing layer 8. Several sets of fixing bolts 10 are installed at the connection between the mounting plate 9 and the outer shell 1. The sealing layer 8 and the pressure sensor 5 are securely installed by the mounting plate 9 and the fixing bolts 10 to improve the sealing performance of the outer shell 1.

[0035] Working principle: High-pressure refrigerant enters the outer shell 1 through the outlet pipe 204. Since several sets of risers 201 are connected by several sets of bends 202, the high-pressure refrigerant then enters several sets of risers 201. When flowing through several sets of risers 201, the effective heat exchange area is increased by the strengthening mechanism 3. The heat is transferred through the tube wall of the heat exchange tube mechanism 2 and the strengthening mechanism 3. Finally, the refrigerant flows out from the outlet pipe 204. Among them, the fins 301 are designed with a special shape to generate secondary flow, enhance the heat disturbance of the hot and cold medium, destroy the thermal resistance layer, improve the heat exchange efficiency, and reduce energy consumption. Before the high-pressure refrigerant enters the inlet pipe 203, it passes through the filter shell 401. Through the double filtration of the coarse filter layer 403 and the fine filter layer 404, the cleanliness of the high-pressure refrigerant is improved, the scale formation in the heat exchange tube mechanism 2 is reduced, and the maintenance requirements of the heat exchange tube mechanism 2 are greatly reduced.

[0036] Among them, the pressure sensor 5 and temperature sensor 7 can monitor the pressure and temperature of the refrigerant in the inlet pipe 203 and outlet pipe 204 in real time, providing data support when the device malfunctions, thus improving its practicality. The controller 6 feeds back the data from the pressure sensor 5 and temperature sensor 7 to the mobile terminal, making it convenient for staff to check the operating status of the device at any time.

[0037] Meanwhile, the fins 301 reduce dust and dirt on their surface, ensuring heat dissipation; the mounting plate 9 and fixing bolts 10 securely install the sealing layer 8 and pressure sensor 5, improving the sealing performance of the housing 1.

[0038] In addition, the connection between the inlet pipe 203 and the outlet pipe 204 and the external pipe via the connecting flange 11 improves the sealing performance when the inlet pipe 203 and the outlet pipe 204 are connected to the external pipe.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
