Problems solved by technology

[0004] Although the above-mentioned measures can ensure the cooling effect of the air conditioner when the vehicle is at high temperature and low speed, there are defects at the same time. The increase will also greatly increase the discharge of the compressor. If the original heat is exchanged, the heat exchange of the condenser will be greater than the sum of the heat absorption of the evaporator and the work of the compressor, while the heat exchange of the condenser The amount is fixed. In order to ensure energy conservation, the evaporator end must be overcooled, resulting in the temperature of the air outlet being too low, which affects the perception of passengers in the car.
If the vehicle is in this high-speed, low-temperature operating condition for a long time, due to the long-term excessive cooling of the evaporator, the evaporator will freeze, resulting in the cooling failure of the air conditioning system
[0005] In order to avoid the failure of the air conditioning system, in the prior art, the method of stopping the compressor is used to balance the heat absorption and heat dissipation of the system. Although this method can alleviate the excessive cooling of the evaporator, when the vehicle is running at high speed and low temperature, It is necessary to start and stop the compressor frequently, which reduces the life of the compressor, and the start and stop of the compressor will also cause severe fluctuations in the temperature of the air outlet, which will reduce the comfort of the passengers in the car. At the same time, the start and stop of the compressor will inevitably make the vehicle There is a phenomenon of jumping when driving, which will also affect the comfort of passengers in the car
In addition, at present, the start-stop control of the compressor is carried out through the thermistor, and the thermistor works for a long time in a humid environment with severe temperature changes, and its reliability is damaged. Once the resistance value is abnormal, the system will cause refrigeration. If the effect is poor, it may even lead to severe frosting and icing on the evaporator

Abstract

The invention provides an executor for an air conditioning condenser liquid collection pipe. The executor comprises a supporting plate, a plugging part and a driving mechanism, wherein the supporting plate is hermetically and fixedly arranged in a liquid collection pipe body and is provided with a through hole; a gap is reserved between the plugging part and the inner wall of the liquid collection pipe; the plugging part can be used for plugging the through hole; and the driving mechanism is used for driving the plugging part to get in or get out of plugging fit with the through hole. Meanwhile, the invention also provides the liquid collection pipe applying the executor and an air conditioning condenser with the liquid collection pipe. The executor has a simple structure; and the control over the area of refrigerating fluid to flow through the condenser is realized through control over the executor and in combination with the effect of a sealing plate so as to adapt to refrigeration under different vehicle conditions, guarantee the performance of an air conditioning system and prolong the life of the air conditioning system.

Description

technical field [0001] The invention relates to an on-off actuator, and also relates to an air-conditioning liquid collecting pipe and a condenser provided with the on-off actuator. Background technique [0002] As vehicles have gradually become an important means of transportation in people's lives, consumers have higher and higher requirements for their performance. Among them, the air conditioning system is one of the important systems of the vehicle, and its performance directly affects the sensory comfort of the passengers in the vehicle. Since the air-conditioning system of the car is refrigerated through the condenser, the specific principle is: the refrigerant flows into the condenser from the liquid inlet on the condenser liquid collection pipe under the drive of the compressor, and flows through the flat tubes of the condenser. During the circulation process, the refrigerant liquid can dissipate heat to the outside air. Finally, the refrigerant liquid that dissip...
