Description

Condenser and air conditioner

Technical Field

The application relates to the technical field of air conditioning, for example to a condenser and an air conditioner.

Background

In the refrigeration process, the condenser theoretically plays a role of isobaric heat release, high-pressure gas comes out of the compressor, the flow rate is very high, and in order to reduce pressure loss, multi-way flow division is designed. However, although the refrigerant flowing out of the compressor is in a gaseous state during the heat radiation process, and after the refrigerant flows into the condenser to perform heat radiation, the refrigerant flowing out of the condenser is in a liquid state, and the refrigerant gradually changes from the gaseous state to the liquid state in the condenser, the refrigerant also exists in a state of coexisting gas and liquid during the flow of the refrigerant in the condenser.

The volume of the refrigerant is reduced after the refrigerant changes from the gaseous state to the liquid state, so that more flow paths are not needed, and if the flow paths are more, the pressure is reduced. In the existing structure form that the condenser n enters and exits, the refrigerant flows through the condenser and changes from gas state to liquid state, so the volume is reduced, but the pipeline volume of the condenser is not changed, so the problem of pressure loss exists, the temperature of the refrigerant entering the evaporator is increased, and the refrigeration effect of the air conditioner is reduced.

Referring to fig. 1 to 5, a condenser according to an embodiment of the present disclosure includes a plurality of heat dissipation pipes, a first pipe 10, a second pipe 20, and a first one-way conduction member 40. The first pipeline 10 is formed by extending from the heat dissipation pipeline, and a plurality of first pipelines 10 are arranged in parallel; the second pipeline 20 is communicated with the adjacent first pipeline 10 and is used for collecting the refrigerant in the adjacent first pipeline 10; the first one-way communication member 40 is provided in the first pipeline 10. The refrigerant in the heat dissipation pipe flows into the first pipe 10, and flows into the second pipe 20 through the stopping of the first one-way communication member 40.

By adopting the condenser provided by the embodiment of the disclosure, after the refrigerant is radiated by the radiating pipeline, the refrigerant is changed into a liquid state or a gas-liquid coexisting state, flows into the first pipeline 10, and is stopped flowing by the first one-way conduction piece 40, so that the refrigerant in the adjacent first pipeline 10 converges to the second pipeline 20, and the liquid refrigerant collected in the second pipeline 20 can fill the pipeline, thereby reducing the pressure loss in the pipeline, ensuring the temperature of the refrigerant flowing out of the condenser, further ensuring the temperature of the refrigerant of the evaporator, and being beneficial to improving the refrigeration effect of the air conditioner.

The condenser is also called a radiator, and the purpose of the condenser is to make the high-pressure superheated steam discharged from the compressor release heat when flowing through the pipeline and condense into liquid refrigerant, and the released heat is transferred to the surrounding low-temperature medium, and the high-pressure superheated refrigerant steam releases heat in the condenser and becomes liquid. The temperature and pressure of the refrigerant vapor are required to be kept constant when the refrigerant vapor is condensed and liquefied in the condenser, and the corresponding temperature and pressure are referred to as a condensation temperature and a condensation pressure. Wherein the condensation temperature increases with increasing condensation pressure.

The condenser rapidly dissipates heat and cools high-pressure superheated refrigerant vapor from the compressor through a plurality of heat dissipation pipelines, and the heat dissipation efficiency of the condenser is higher as the number and the heat transfer area of the heat dissipation pipelines are larger. On the other hand, when the refrigerant in the condenser dissipates heat and liquefies, the refrigerant in the heat radiation line of the condenser exists not only in a gas state and a liquid state but also in a gas-liquid coexisting state.

In the embodiment of the present application, under the refrigeration condition, the refrigerant is changed into a liquid state or a gas-liquid coexisting state after being dissipated through the heat dissipating pipeline, and the refrigerant flows into the first pipeline 10 along the heat dissipating pipeline, and is stopped flowing through the first one-way conducting piece 40 disposed on the first pipeline 10, so that the refrigerant no longer flows along the first pipeline 10, but flows into the second pipeline 20 communicated with the first pipeline 10. In this way, the refrigerant in the adjacent first pipeline 10 can be converged by the second pipeline 20, and after the two liquid refrigerants are converged, the volume change caused by the refrigerant form change, and further the pressure in the pipelines can be prevented from changing, thereby avoiding the problem of pressure loss.

Fig. 1 shows the flow path of the refrigerant within the condenser during a cooling condition. Wherein the arrows indicate the flow direction of the refrigerant.

Fig. 2 shows the flow path of the refrigerant in the condenser under heating conditions. Wherein the arrows indicate the flow direction of the refrigerant.

Optionally, the second circuit 20 collects at least two of the refrigerants in the first circuit 10. The second line 20 may also collect a plurality of refrigerant in the first line 10 to ensure pressure in the line containing liquid refrigerant in the condenser. In practical applications, it is preferable that the number of the first pipelines 10 is 2n, and the number of the second pipelines 20 is less than or equal to n. Wherein n is more than or equal to 1 and is an integer.

The first pipeline 10 is divided into a first flow-through segment 101 and a second flow-through segment 102 by a first one-way communication member 40. Under the refrigeration condition, after the refrigerant radiates heat through the heat radiation pipeline, the refrigerant flows into the first circulation pipe section 101 of the first pipeline 10 along the heat radiation pipeline, and the flow of the refrigerant is stopped through the first one-way conduction piece 40 arranged on the first pipeline 10, so that the refrigerant does not flow along the first pipeline 10 any more, namely does not flow into the second circulation pipe section 102, but flows into the second pipeline 20 communicated with the first pipeline 10. In practical applications, the second flow-through segments 102 of the first plurality of pipelines 10 are communicated through a pipeline, that is, the outlets of the second plurality of flow-through segments 102 are collected into one pipeline.

Optionally, the condenser further comprises a second one-way conducting member 50, and the second one-way conducting member 50 is disposed on the second pipeline 20 to cut off a flow path from the second pipeline 20 to the first pipeline 10.

The second one-way communication piece 50 provided in the second pipe line 20 can block the flow path from the second pipe line 20 to the first pipe line 10. It can be understood that, in the heating condition, the refrigerant flows in the reverse direction, and the refrigerant is prevented from flowing to the first line 10 through the second line 20 by the second one-way communication member 50.

Under a heating condition, the refrigerant flows from the second flow-through section 102 of the first line 10 to the first flow-through section 101, and then flows into the heat-radiating line. The circulation paths of the refrigerant are increased compared with the circulation paths under the refrigeration working condition, so that the heat exchange effect of the refrigerant can be enlarged, the refrigerant absorbs heat in an evaporation mode, the liquid refrigerant is changed into the gaseous refrigerant, the space required by the gaseous refrigerant is increased, and the pressure in the pipeline can be kept unchanged after the refrigerant is changed into the gaseous refrigerant by enlarging the number of the flow paths.

Optionally, the second circuit 20 comprises: a first pipe segment 201, a second pipe segment 202 and a third pipe segment 203. The first pipe section 201 is communicated with a first pipeline 10 and is provided with a second one-way conduction piece 50; the second pipe section 202 is communicated with another adjacent first pipeline 10 and is provided with a second one-way conduction piece 50; third tube segment 203 communicates first tube segment 201 and second tube segment 202 to collect the refrigerant in first tube segment 201 and second tube segment 202. Wherein the conducting direction of the second one-way conducting element 50 in the first pipe section 201 is opposite to that of the second one-way conducting element 50 in the second pipe section 202.

The refrigerant of one first pipeline 10 is diverted to the third pipeline section 203 through the first pipeline section 201, and the refrigerant of another adjacent first pipeline 10 is diverted to the third pipeline section 203 through the second pipeline section 202, so that the refrigerants of the adjacent first pipelines 10 are merged.

Wherein the communication between the first pipe segment 201 and the first pipeline 10 is located at the first flow-through pipe segment 101 or the separation between the first flow-through pipe segment 101 and the second flow-through pipe segment 102. The connection of the second pipe section 202 to the first pipe 10 is at the first flow-through pipe section 101 or the separation of the first flow-through pipe section 101 from the second flow-through pipe section 102.

In practical applications, when adjacent first pipelines 10 are arranged in parallel, in the present embodiment, "the conducting direction of the second one-way conducting element 50 in the first pipe section 201 is opposite to that of the second one-way conducting element 50 in the second pipe section 202", it can be understood that: the refrigerant in the first tube section 201 flows in a first direction and the refrigerant in the second tube section 202 flows in a second direction, the first direction and the second direction being opposite to each other. Therefore, the second one-way conduction element 50 of the first pipe section 201 is conducted along the first direction, and the second one-way conduction element 50 of the second pipe section 202 is conducted along the second direction. The first direction or the second direction is the direction from the first pipeline 10 to the third pipeline section 203. As shown in connection with fig. 1.

Optionally, the condenser further comprises: the third pipe line 30 communicates with the adjacent second pipe line 20 to collect the refrigerant in the second pipe line 20.

The third pipe line 30 is communicated with the adjacent second pipe line 20, the refrigerant in the second pipe line 20 is collected, the refrigerant in the condenser can be further converged, the pressure change in the pipe line caused by the volume change due to the refrigerant form change is avoided, and the problem of pressure loss is avoided.

Alternatively, the third conduit 30 may be "T" shaped.

Optionally, the third conduit 30 includes a first communication port, a second communication port, and a third communication port. The first communication port is communicated with the outlet of the third pipe section 203 of one second pipeline 20, and the second communication port is communicated with the outlet of the third pipe section 203 of another adjacent second pipeline 20. The refrigerant flowing in from the first communication port and the second communication port is guided to the third communication port through the pipe, and the refrigerant is discharged from the third communication port.

In the embodiment of the present application, the flow areas of the heat dissipation pipe, the first pipe 10, the second pipe 20, and the third pipe 30 are partially or entirely the same. In practical application, the appropriate flow area can be selected according to practical situations. In addition, the third pipelines and the third flow ports of the first pipelines are finally converged to the liquid outlet of the condenser.

Optionally, the first unidirectional conducting part 40 and/or the second unidirectional conducting part 50 comprise: a valve body 401 and a valve spool 402. The valve body 401 is configured with a flow passage 4011; the valve core 402 is arranged in the flow passage 4011, the valve core 402 is provided with a hollow structure 4022, one end of the valve core 402 is provided with a valve core inlet 4021 communicated with the hollow structure 4022, the other end of the valve core 402 is provided with a flow stopping part 4023, and the flow stopping part 4023 is used for stopping the flow of the refrigerant in the flow passage 4011. A plurality of valve core outlets 4024 communicating with the hollow structure 4022 are opened along the circumferential direction of the valve core 402.

The valve body 402 is disposed in the flow passage 4011, and can reciprocate in the valve body 401 by the urging action of the flow of the refrigerant. The valve body 401 includes opposing first and second ends. The refrigerant enters the flow channel 4011 from the first end of the valve body 401, flows into the valve core 402 through the valve core inlet 4021, and is stopped by the flow stop portion 4023, so that the valve core 402 is pushed to move to the second end of the valve body 401. When the flow stop portion 4023 of the valve body 402 abuts against the second end of the valve body 401, the flow channel 4011 in the valve body 401 is closed, as shown in fig. 3, that is, the refrigerant cannot pass through the flow channel 4011 in the valve body 401, so that the purpose of one-way conduction of the first one-way conduction piece 40 or the second one-way conduction piece 50 is achieved.

The hollow structure 4022 is formed by a sidewall bounding formation of the spool 402. The hollow structure 4022 of the valve body 402 is a passage through which a refrigerant can flow. One end of the valve core 402 is provided with a valve core inlet 4021 communicating with the hollow structure 4022, and the other end is configured with a flow stop portion 4023. Thus, the fluid can be prevented from flowing into the hollow structure 4022 from the valve body inlet 4021 and then flowing out from the other end.

Optionally, the valve core 402 is a cylinder structure, and the length of the valve core 402 is greater than or equal to the length of the hollow structure 4022 along the axial direction of the valve core 402.

Optionally, the flow area of the spool inlet 4021 is equal to the flow area of the hollow structure 4022. In this way, when the refrigerant enters the hollow structure 4022 from the valve element inlet 4021, the pressure can be prevented from changing due to the change of the flow area, and the refrigerant can act on the valve element 402, so that the valve element 402 jumps, and the stable translation cannot be performed.

Optionally, the spool inlet 4021 has a circular or square cross-section. Optionally, the cross-section of the hollow structures 4022 is circular or square. The valve core inlet 4021 and the hollow structure 4022 are preferably circular in cross-section. Thus, the processing, the manufacturing and the cleaning are convenient.

The valve core outlets 4024 are formed along the circumferential direction of the valve core 402, and the valve core outlets 4024 are uniformly arranged at intervals. In this way, when the refrigerant is discharged through the valve core outlet 4024, the valve core 402 is uniformly affected by the refrigerant by the valve core outlets 4024 being arranged at regular intervals, that is, the stability of the valve core 402 in the use process is improved.

Alternatively, the shape of the spool outlet 4024 may be circular or rectangular. According to actual conditions, the processing and manufacturing are carried out.

In the embodiment of the present application, when the refrigerant flows into the flow channel 4011 from the second end of the valve body 401, the refrigerant pushes the flow stop portion 4023, so that the valve body 402 moves linearly to the first end of the valve body 401 and abuts against the first end. At this time, the refrigerant enters through the valve spool outlet 4024, flows into the hollow structure 4022 of the valve spool 402, flows to the second end of the valve body 401 through the valve spool inlet 4021, and then flows out. Under the condition that the valve core inlet 4021 of the valve core 402 is abutted to the first end of the valve body 401, the flow channel 4011 in the valve body 401 is in a conduction state, as shown in fig. 4, namely, the refrigerant can flow in the flow channel 4011 of the valve body 401, so that the purpose of one-way conduction of the first one-way conduction piece 40 or the second one-way conduction piece 50 is achieved.

Optionally, the flow stop 4023 extends from the circumferential edge of the valve spool 402 toward the axis of the valve spool 402, converges and closes. As shown in connection with fig. 5.

In the embodiment of the application, the flow stopping portion 4023 extends from the circumferential edge of the valve core 402 to the axis of the valve core 402, and is closed, so that on one hand, the refrigerant can be prevented from flowing out of the flow stopping portion 4023 from the hollow structure 4022; on the other hand, the flow stop portions 4023 are of a symmetrical structure, and when the refrigerant acts on the flow stop portions 4023, the regions of the flow stop portions 4023 of the valve core 402 are uniformly stressed, so that the stability and the service life of the valve core 402 in the use process are ensured.

Alternatively, the flow stop 4023 is formed in an outwardly extending configuration relative to the hollow structure 4022.

Optionally, the flow stop 4023 comprises a conical surface having an apex on the axis of the valve element 402.

Through the conical surface of the flow stopping portion 4023, when the refrigerant acts on the flow stopping portion 4023, the refrigerant is diverted from the vertex of the conical surface along the conical surface, so that the instantaneous impact force of the refrigerant on the valve element 402 can be reduced, and further the impact force of the valve element 402 on the first end of the valve body 401 under the pushing of the refrigerant is avoided.

The vertex of the conical surface is located on the axis of the valve core 402, and when the refrigerant acts on the flow stopping portion 4023, all areas of the flow stopping portion 4023 of the valve core 402 are uniformly stressed, so that the stability and the service life of the valve core 402 in the use process are ensured.

Optionally, the outer surface of the flow stopping portion 4023 is a tapered surface, and the inner surface of the flow stopping portion 4023 is also a tapered surface. In this way, after the refrigerant flowing from the hollow structure 4022 to the inside of the flow stop portion 4023 is blocked, the refrigerant is branched along the tapered surface, so that the instant impact force of the refrigerant on the valve element 402 can be reduced, and the impact force of the valve element 402 on the second end of the valve body 401 under the pushing of the refrigerant is avoided.

Alternatively, the apex of the inner surface of the flow stop 4023 is disposed opposite the apex of the outer surface. In this way, it is helpful to make the structure of the flow stop 4023 symmetrical, so that the force is uniformly applied.

Optionally, the valve body 401 includes a stopper 4012, the stopper 4012 being configured at an end of the valve body 401. The flow stopping portion 4023 selectively disengages from or collides with the stopper portion 4012 to conduct or stop the flow of the refrigerant in the flow channel 4011.

When the flow stopper 4023 is disengaged from the stopper 4012, the flow passage 4011 of the valve body 401 is in a conductive state, and the refrigerant can flow in the flow passage 4011. When the flow stopper 4023 abuts against the stopper 4012, the flow passage 4011 of the valve body 401 is closed, and the refrigerant cannot flow in the flow passage 4011.

Alternatively, the stopper portion 4012 may be provided around the inner sidewall of the valve body 401. The minimum inner diameter of the limiting part 4012 is smaller than the outer diameter of the valve core inlet 4021 end of the valve core 402. Alternatively, the stopper 4012 is provided in a partial region of the inner sidewall of the valve body 401. Wherein, spacing portion 4012 is two at least, and relative setting. The distance between the two limiting portions 4012 is smaller than the outer diameter of the valve core inlet 4021 end of the valve core 402. Thus, the valve body 401 can be prevented from slipping out of the valve body 402 by the stopper 4012.

Alternatively, the stopper 4012 is formed around the valve body 401 so as to be inclined inward from the circumferential edge thereof. It can be understood that the limiting portion 4012 is truncated cone-shaped, and an inlet of the flow passage 4011 of the valve body 401 is disposed in the middle. Wherein, the wall thickness of the limiting part 4012 is the same. That is, the inside of the stopper 4012 has a circular truncated cone structure.

Optionally, part or all of the outer surface of the flow stop portion 4023 is attached to the inner surface of the limiting portion 4012.

When part or all of the outer surface of the flow stopper 4023 is in contact with the inner surface of the stopper 4012, the flow stopper 4023 contributes to the flow stopping action of the flow stopper 4011 on the flow channel 4011, and prevents the refrigerant from flowing out from the gap between the flow stopper 4023 and the stopper 4012. The area where the flow stopping part 4023 is attached to the limiting part 4012 can form a circle in a surrounding mode.

The embodiment of the disclosure provides an air conditioner, which comprises the condenser provided by any one of the embodiments.

By adopting the air conditioner provided by the embodiment of the disclosure, after the refrigerant is radiated by the radiating pipeline of the condenser, the refrigerant is changed into a liquid state or a gas-liquid coexisting state, flows into the first pipeline 10, and is stopped flowing by the first one-way conduction piece 40, so that the refrigerant in the adjacent first pipeline 10 converges to the second pipeline 20, and the liquid refrigerant collected in the second pipeline 20 can fill the pipeline, thereby reducing the pressure loss in the pipeline, ensuring the temperature of the refrigerant flowing out of the condenser, and being beneficial to improving the refrigeration effect of the air conditioner.
