Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner condensers, and particularly relates to a liquid collecting pipe assembly for an automotive air conditioner condenser. Background Technique

[0002] As an important part of the air conditioning system, the main function of the air conditioner condenser is to realize the conversion of the refrigerant from gaseous state to liquid state, thereby releasing heat and reducing the indoor temperature. During the air conditioning cycle, the high-temperature and high-pressure gaseous refrigerant enters the condenser and gradually cools and condenses into a liquid through heat exchange with the outside air or water. This process not only requires the condenser to have good heat dissipation performance to ensure that the refrigerant can be fully condensed, but also requires it to be structurally compact and corrosion-resistant to adapt to the needs of different environments and working conditions. The design and optimization of the air conditioner condenser are directly related to the refrigeration efficiency, energy consumption, and service life of the entire air conditioning system.

[0003] The liquid collecting pipe of the air conditioner condenser is a key component connecting the condenser and other components of the refrigeration system. Its main function is to collect and transport the liquid refrigerant flowing out of the condenser. During the condensation process, the liquid refrigerant gathers in the liquid collecting pipe and is transported to components such as the expansion valve and evaporator through the pipeline system to complete the refrigeration cycle. The design of the liquid collecting pipe needs to consider the flow rate and pressure of the refrigerant as well as the overall layout of the system to ensure that the liquid refrigerant can flow smoothly and evenly. At the same time, the liquid collecting pipe also needs to have a certain liquid storage capacity to cope with the fluctuations of the refrigerant when the system load changes. Therefore, the liquid collecting pipe of the air conditioner condenser plays a crucial role in the refrigeration system, and its performance directly affects the stability and refrigeration effect of the entire system.

[0004] Patent document CN215413355U discloses a condenser liquid collecting pipe assembly, including a main connection pipe. A main liquid collecting pipe assembly channel is fixedly arranged on one side of the main connection pipe. The main liquid collecting pipe assembly channel is connected to the main connection pipe by welding. A socket ring is movably installed on the other side of the main connection pipe. A shunt member is arranged on one side of the socket ring. The shunt member is provided with several groups of connection heads. A liquid collecting pipe is fixedly connected to one side of the connection head. A fixing ring is sleeved in the middle of the liquid collecting pipe. A quick-connect installation head is arranged at one end of the liquid collecting pipe. A connection thread is provided inside the quick-connect installation head. A protective layer is sleeved on the surface of the liquid collecting pipe. By arranging a filter screen layer inside the main connection pipe, the liquid entering the condenser can be filtered to prevent impurities in the liquid from affecting the operation of the condenser. At the same time, the detachable filter screen layer also facilitates installation and subsequent replacement.

[0005] As in the prior art of the above-mentioned patent, the liquid collecting pipe of the condenser, as a pipe for temporarily storing condensate, is usually designed to receive condensate through the input pipe and release it through the output pipe when needed. Its volume is generally sufficient to accommodate the amount of condensate generated by the device under normal working conditions. However, in certain specific cases, the amount of condensate will surge, which is mainly due to a sudden increase in system load, a decrease in cooling efficiency, or a sharp change in condensation conditions. Faced with this abnormal increase in condensate, traditional liquid collecting pipes often lack effective countermeasures, resulting in a sharp increase in the pressure in the pipe, which may not only affect the condensation efficiency, but in severe cases may even cause damage to the liquid collecting pipe itself, such as rupture and leakage of the pipe body, thereby threatening the stable operation and safety of the entire condensation system.

When the liquefied condensate in the liquid collecting pipe 1 is input through the access pipe 4 and enters the inside of the liquid collecting pipe 1 through the input ports 13 on the side wall of the input pipe 2 for storage. When in use, it is output from the output assembly again. When the coolant in the liquid collecting pipe 1 is excessive, that is, when the coolant reaches the threshold, the floating ball 14 moves upward under the action of the condensate, thereby pushing the plugging plate 9 to block the input port 13. At this time, the condensate cannot enter the liquid collecting pipe 1 anymore, thus realizing the protection of the liquid collecting pipe 1 and preventing excessive condensate from damaging the liquid collecting pipe 1.

[0028] As a preferred technical solution of this embodiment, the limiting component includes four limiting grooves 7, and the four limiting grooves 7 are respectively opened on the inner walls on both sides of the input pipe 2.
