Description

Technical Field

[0001] The utility model relates to the technical field of condenser flow paths, and specifically relates to an improved air conditioner condenser flow path. Background Technique

[0002] When a household air conditioner is refrigerating, the heat exchanger in the outdoor unit is called a condenser. During the heat release process, the high-temperature and high-pressure gaseous freon exchanges heat with the air outdoors and becomes low-temperature and high-pressure liquid freon. For the flow path distribution of the U-shaped heat exchange tubes inside the existing condenser, the positions of most intake pipes and liquid outlet pipes are not clearly defined, resulting in uneven distribution of the refrigerant gas during condensation.

[0003] For example, a multi-connected air conditioner condenser flow path with the publication number CN218120262U includes several U-shaped heat exchange tubes. A plurality of aluminum foil fins are expanded and connected to the outside of the U-shaped heat exchange tubes. Fixing plates located on both sides of the plurality of aluminum foil fins are expanded and connected to the outside of the U-shaped heat exchange tubes. The several U-shaped heat exchange tubes include elbows, short U-shaped tubes, medium U-shaped tubes, and long U-shaped tubes. The flow path inlet and outlet positions of each heat exchange tube are clearly defined for cross-countercurrent heat exchange, and the condenser wind direction is clearly defined. This heat exchange tube layout form can improve the economy of the refrigeration cycle and play an energy-saving role.

[0004] The above-mentioned air conditioner condenser flow path enables the internal gas and liquid to flow through the setting of the U-shaped heat exchange tube. Since the inside of the U-shaped heat exchange tube is a straight-through structure and there is no blocking device for the gas and liquid in the U-shaped heat exchange tube, the flow rate of the gas and liquid inside the U-shaped heat exchange tube is relatively fast. When the temperature is too high, the cooling efficiency will decrease, and the temperature may not drop, thus affecting the refrigeration effect of the air conditioner. Content of the Utility Model

[0005] The purpose of the utility model is to provide an improved air conditioner condenser flow path to solve the problem that in the current market, the flow rate of gas and liquid inside the U-shaped heat exchange tube is relatively fast. When the temperature is too high, the cooling efficiency will decrease, and the temperature may not drop, thus affecting the refrigeration effect of the air conditioner as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An improved air conditioner condenser flow path includes fins and U-shaped heat exchange tubes, and the U-shaped heat exchange tubes are inserted into the inside of the fins;

[0007] It further includes: a connector is installed at the end position of the U-shaped heat exchange tube, and the connector is arranged in a "U" shape;

[0008] Guide plates are evenly installed inside the U-shaped heat exchange tubes. Through holes are opened inside the guide plates. Through the setting of the through holes and the guide plates, the flow rate of the gas inside the U-shaped heat exchange tubes can be reduced, and thus the residence time of the gas inside the U-shaped heat exchange tubes becomes longer.

[0009] Preferably, an air inlet pipe and a liquid outlet pipe are respectively installed at the upper right end and the lower right end of the U-shaped heat exchange tube, and the distance between two adjacent U-shaped heat exchange tubes is equal to the width of the connector, and the connector is used to connect two adjacent U-shaped heat exchange tubes.

[0010] Preferably, a connecting pipe is installed at the right ends of the air inlet pipe and the liquid outlet pipe, a baffle is installed inside the connecting pipe, the diameter of the baffle is the same as the inner diameter of the connecting pipe, and both the upper and lower ends of the connecting pipe are open.

[0011] Preferably, the guide plate is arranged in a frustum structure, the thickness around the guide plate is the same, and the through-hole structure inside the guide plate is the same as the guide plate structure.

[0012] Preferably, both the left and right ends of the U-shaped heat exchange tube protrude beyond the outer ends of the fins, and there are 2 groups of U-shaped heat exchange tubes.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The present utility model is provided with a guide plate and a through hole. The through hole is opened inside the guide plate, and the structure of the guide plate is a frustum structure. After the gas contacts the guide plate, it will block the guide plate, reducing the flow velocity of the gas. As a result, the residence time of the gas inside the U-shaped heat exchange tube becomes longer, enabling the gas to be fully condensed, avoiding poor cooling effect when the temperature is too high, and improving the refrigeration effect of the air conditioner.

[0015] 2. The present utility model is provided with a U-shaped heat exchange tube and a connector. The connector is installed between two adjacent U-shaped heat exchange tubes, enabling multiple U-shaped heat exchange tubes to be connected together. Thus, the gas can flow from the uppermost U-shaped heat exchange tube to the lowermost U-shaped heat exchange tube, allowing the gas to pass through all the U-shaped heat exchange tubes, increasing the number of U-shaped heat exchange tubes the gas passes through, and thereby lengthening the gas path.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-5 , the present invention provides the following technical solutions:

[0024] An improved air conditioner condenser flow path includes a fin 1 and a U-shaped heat exchange tube 2, and the U-shaped heat exchange tube 2 is inserted into the interior of the fin 1; it further includes: a connector 9 is installed at the end position of the U-shaped heat exchange tube 2, and the connector 9 is arranged in a "U" shape; an inlet pipe 3 and a liquid outlet pipe 4 are respectively installed at the upper right end and the lower right end of the U-shaped heat exchange tube 2, and the distance between adjacent two U-shaped heat exchange tubes 2 is equal to the width of the connector 9, and the connector 9 is used to connect adjacent two U-shaped heat exchange tubes 2. A connecting pipe 5 is installed at the right ends of the inlet pipe 3 and the liquid outlet pipe 4, a baffle 8 is installed inside the connecting pipe 5, the diameter of the baffle 8 is the same as the inner diameter of the connecting pipe 5, and both the upper and lower ends of the connecting pipe 5 are open.

[0025] Insert the U-shaped heat exchange tube 2 into the corresponding position, then install the connector 9 between adjacent two U-shaped heat exchange tubes 2. Through the setting of the connector 9, multiple U-shaped heat exchange tubes 2 are connected. Then install the inlet pipe 3 and the liquid outlet pipe 4 at the upper and lower ends of the U-shaped heat exchange tube 2 respectively, and install the ends of the inlet pipe 3 and the liquid outlet pipe 4 on the connecting pipe 5. Gas is introduced through the upper end of the connecting pipe 5, and the baffle 8 cuts off the connecting pipe 5 to prevent gas from flowing out through the lower end of the connecting pipe 5, so that the gas enters the interior of the U-shaped heat exchange tube 2 through the inlet pipe 3. The U-shaped heat exchange tube 2 and the fin 1 cool the gas. When the hot gas encounters the low temperature, it will condense into water droplets, and the water droplets flow into the connecting pipe 5 through the liquid outlet pipe 4.

[0026] Guide plates 6 are evenly installed inside the U-shaped heat exchange tube 2, through holes 7 are formed inside the guide plates 6. Through the settings of the through holes 7 and the guide plates 6, the flow rate of the gas flowing inside the U-shaped heat exchange tube 2 can be reduced, so that the residence time of the gas inside the U-shaped heat exchange tube 2 becomes longer. The guide plates 6 are arranged in a frustum shape, the thicknesses around the guide plates 6 are the same, the structure of the through holes 7 inside the guide plates 6 is the same as the structure of the guide plates 6. The left and right ends of the U-shaped heat exchange tube 2 protrude from the outer ends of the fins 1, and there are 2 groups of U-shaped heat exchange tubes 2.

[0027] Through the setting of the guide plate 6, the gas entering the inside of the U-shaped heat exchange tube 2 can be blocked, thereby reducing the flow rate of the gas inside the U-shaped heat exchange tube 2. Then the gas is transported through the through hole 7, so that the residence time of the gas inside the U-shaped heat exchange tube 2 becomes longer. Thus, the U-shaped heat exchange tube 2 can fully cool the gas, making the cooling effect faster, and further improving the refrigeration effect of the air-conditioning condenser. The structure inside the flow path of the air-conditioning condenser is improved, and the processing is relatively simple.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
