Description

Technical Field

[0001] This utility model relates to the technical field of condenser heat exchange equipment, specifically a condenser heat exchange structure. Background Technology

[0002] When refrigeration and air conditioning are in operation, condensers are often used for heat exchange, thus requiring condenser heat exchange equipment. Utility model patent application CN201621408787.6 discloses a condenser structure with high heat exchange efficiency. The structure is simple, lightweight, and easy to use. By setting a first heat exchange channel and a second heat exchange channel within the core, it solves the problems of low heat exchange efficiency and non-compact structure in existing coil-type heat exchangers. The arrangement of the fins not only increases the heat exchange area of ​​the condenser per unit volume but also improves the condenser's turbulence effect on the fluid, making this utility model... This type of device has high heat exchange efficiency. In addition, the partition plate in this invention is relatively thin, and the fins can provide support, ensuring the stability of the structure. According to the disclosed technical solution, existing condenser heat exchange equipment often fails to effectively guarantee the heat dissipation effect of the refrigerant when using the heat exchanger for heat dissipation, resulting in insufficient heat dissipation of the refrigerant, which is detrimental to the cooling effect of the air conditioner. On the other hand, when using the heat exchanger for heat absorption, the refrigerant may not absorb enough heat from the outside air within the heat exchanger, which is also detrimental to the heating effect of the air conditioner.

[0003] Therefore, how to design the heat exchange structure of the condenser has become a problem we need to solve. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a condenser heat exchange structure to solve the problems mentioned in the background technology. This utility model is reasonably designed, convenient to use, and suitable for heat exchange work in refrigeration and air conditioning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a condenser heat exchange structure, comprising a frame and a channel, wherein a heat exchange component is installed on the frame, the heat exchange component includes finned tubes and air ducts, an inlet / outlet component is installed on the frame, the inlet / outlet component includes an upper tube and a lower tube, a connecting component is installed on the frame, the connecting component includes a slot and a fine hole, a movable component is installed inside the slot, the movable component includes a piston and a gate, a thermal control component is installed inside the frame, the thermal control component includes an annular cavity and a connecting hole, and an adjusting component is installed inside the annular cavity, the adjusting component includes an inner cavity and a valve pin.

[0006] Furthermore, the channel is located on the inner side of both ends of the frame, the upper pipe is welded to the top of one end of the frame, and the lower pipe is welded to the bottom of the other end of the frame. Both the upper pipe and the lower pipe are connected to the channel.

[0007] Furthermore, both ends of the finned tubes are welded to the inner wall of the frame, the finned tubes are evenly distributed on the inner side of the frame, and the air duct is formed by the gap between the finned tubes and the inner wall of the frame.

[0008] Furthermore, openings are provided on the inner walls at both ends of the frame, and both ends of the finned tube are connected to the channel through the openings.

[0009] Furthermore, the slot is located on the inner side of one end of the frame, the piston is engaged on the inner wall of one end of the slot, and one end of the slot is connected to the outer side of the frame through a small hole.

[0010] Furthermore, the gate is welded to the piston, one end of the gate passes through the slot and extends to the inside of the opening, and the piston is connected to the inner wall of the other end of the slot by a spring.

[0011] Furthermore, both the annular cavity and the inner cavity are located on the inner side of the other end of the frame. The inner cavity and the annular cavity are distributed at the top and bottom of the opening, and the inner cavity is connected to the annular cavity through a connecting hole.

[0012] Furthermore, one end of the valve pin is engaged with the inner wall of the inner cavity, and the other end of the valve pin passes through the inner cavity and extends to the inner wall of the opening.

[0013] Beneficial effects: 1. When the air conditioner is cooling, the refrigerant enters the inner side of the channel in the frame through the inlet pipe, then flows to the other end of the frame through the finned tubes, and dissipates heat through the air duct. If the refrigerant in some finned tubes does not dissipate heat sufficiently due to insufficient airflow speed in the air duct or other factors, the heat of the refrigerant is conducted to the inner side of the annular cavity. The air in the annular cavity expands, and the expanded air enters the inner side of the inner cavity through the connecting hole, thereby pushing the valve pin to the inner side of the port, closing the opening of the port connected to the finned tube, reducing the flow speed of the refrigerant in the finned tube, so as to ensure that the heat of the refrigerant can be fully dissipated to the outside, avoiding the impact of insufficient heat dissipation of the refrigerant on the cooling speed of the air conditioner, and ensuring the cooling effect of the air conditioner.

[0014] 2. In the heating operation of the air conditioner, the refrigerant of the condenser heat exchange structure enters the inner side of the lower pipe through the pressure relief valve and enters the inner side of the other end of the finned tube through the channel. It absorbs heat from the outside through the finned tube and the air duct. When the refrigerant does not absorb enough heat, when the refrigerant flows to the inner side of the opening located at one end of the frame, the air in the slot contracts, which in turn causes the piston to compress the spring and drive the gate to move inward to the inner side of the opening, reducing the opening of the opening connected to the finned tube and reducing the flow rate of the refrigerant. This allows the refrigerant to absorb enough heat, thereby ensuring the heat of the refrigerant and the heating effect of the air conditioner.

[0015] 3. The condenser has a reasonable heat exchange structure design, is highly efficient and convenient to use, and is suitable for heat exchange in refrigeration and air conditioning. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a condenser heat exchange structure, including a frame 1 and a channel 2. A heat exchange assembly is installed on the frame 1, including finned tubes 3 and air ducts 4. An inlet / outlet assembly is installed on the frame 1, including an upper tube 5 and a lower tube 6. A connecting assembly is installed on the frame 1, including a slot 8 and a fine hole 12. A movable assembly is installed inside the slot 8, including a piston 9 and a gate 10. A thermal control assembly is installed inside the frame 1, including an annular cavity 13 and connecting holes 16. An adjusting assembly is installed inside the annular cavity 13, including an inner cavity 14 and a valve pin 15. Through-holes 7 are provided on the inner walls at both ends of the frame 1. Both ends of the finned tubes 3 are connected to the channel 2 through the through-holes 7. The slot 8 is located inside one end of the frame 1, and the piston 9 is engaged at one end of the slot 8. On the inner wall, one end of the slot 8 is connected to the outer side of the frame 1 through a fine hole 12. The gate 10 is welded to the piston 9. One end of the gate 10 passes through the slot 8 and extends to the inner side of the opening 7. The piston 9 is connected to the inner wall of the other end of the slot 8 through a spring 11. When the air conditioner is in heating mode, the refrigerant of the air conditioner enters the inner side of the lower pipe 6 through the pressure relief valve and enters the inner side of the other end of the finned tube 3 through the channel 2. It absorbs heat from the outside through the finned tube 3 and the air duct 4. When the refrigerant does not absorb enough heat, when the refrigerant flows to the inner side of the opening 7 located at one end of the frame 1, the air in the slot 8 contracts, which causes the piston 9 to compress the spring 11 and drive the gate 10 to move to the inner side of the opening 7, closing the opening of the opening 7 connected to the finned tube 3 and reducing the flow rate of the refrigerant so that the refrigerant can absorb enough heat, thereby ensuring the heat of the refrigerant and ensuring the heating effect of the air conditioner.

[0023] In this embodiment, the channel 2 is opened on the inner side of both ends of the frame 1. The upper pipe 5 is welded to the top of one end of the frame 1, and the lower pipe 6 is welded to the bottom of the other end of the frame 1. Both the upper pipe 5 and the lower pipe 6 are connected to the channel 2. Both ends of the finned tube 3 are welded to the inner wall of the frame 1. The finned tubes 3 are evenly distributed on the inner side of the frame 1. The air duct 4 is formed by the gap between the finned tubes 3 and the inner wall of the frame 1. The annular cavity 13 and the inner cavity 14 are both opened on the inner side of the other end of the frame 1. The inner cavity 14 and the annular cavity 13 are both distributed at the top and bottom of the opening 7. The inner cavity 14 is connected to the annular cavity 13 through the connecting hole 16. One end of the valve pin 15 is stuck on the inner wall of the inner cavity 14, and the other end of the valve pin 15 passes through the inner cavity 14 and extends into the opening 7. On the wall, during use, when the air conditioner is cooling, the refrigerant enters the inner side of the channel 2 inside the frame 1 through the inlet pipe 5, then flows to the other end of the frame 1 through the finned tube 3, and dissipates heat through the air duct 4. If the refrigerant in some of the finned tube 3 does not dissipate heat sufficiently due to insufficient airflow speed in the air duct 4 or other factors, the heat of the refrigerant is conducted to the inner side of the annular cavity 13. The air in the annular cavity 13 expands, and the expanded air enters the inner side of the inner cavity 14 through the connecting hole 16, thereby pushing the valve pin 15 to the inner side of the port 7, closing the opening of the port 7 connected to the finned tube 3, reducing the flow speed of the refrigerant in the finned tube 3, so as to ensure that the heat of the refrigerant can be fully dissipated to the outside, avoiding the impact of insufficient heat dissipation of the refrigerant on the cooling speed of the air conditioner, and ensuring the cooling effect of the air conditioner.

[0024] When the air conditioner is cooling, the refrigerant enters the inner side of the channel 2 inside the frame 1 through the inlet pipe 5, then flows to the other end of the frame 1 through the finned tube 3, and dissipates heat through the air duct 4. If the refrigerant in some of the finned tubes 3 does not dissipate heat sufficiently due to insufficient airflow velocity in the air duct 4 or other factors, the heat of the refrigerant is conducted to the inner side of the annular cavity 13. The air in the annular cavity 13 expands, and the expanded air enters the inner side of the inner cavity 14 through the connecting hole 16, thereby pushing the valve pin 15 towards the inner side of the port 7, closing the opening of the port 7 connected to the finned tube 3, reducing the flow velocity of the refrigerant in the finned tube 3, so as to ensure that the heat of the refrigerant can be fully dissipated outward, and to avoid heat loss due to refrigerant condensation. Insufficient heat dissipation can affect the cooling speed of the air conditioner. To ensure the cooling effect of the air conditioner, when the air conditioner is in heating mode, the refrigerant enters the inner side of the lower pipe 6 through the pressure relief valve and enters the inner side of the other end of the finned tube 3 through the channel 2. It absorbs heat from the outside through the finned tube 3 and the air duct 4. When the refrigerant absorbs insufficient heat, when the refrigerant flows to the inner side of the opening 7 located at one end of the frame 1, the air in the slot 8 contracts, which causes the piston 9 to compress the spring 11 and drive the gate 10 to move to the inner side of the opening 7, reducing the opening degree of the opening 7 connected to the finned tube 3 and reducing the flow rate of the refrigerant so that the refrigerant can absorb enough heat, thereby ensuring the heat of the refrigerant and thus ensuring the heating effect of the air conditioner.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
