Description

Technical Field

Background

For screw units, the flow and the oil temperature control of the frozen oil are two key factors for ensuring the stable operation of the unit, particularly the oil temperature control, and at present, a plate heat exchanger is commonly used for exchanging heat of oil of the system by utilizing a refrigerant circulating in the system, so that the aim of reducing the oil temperature of the unit is fulfilled.

However, for smaller units, the following problems cannot be solved when an independent plate heat exchanger is used for controlling the oil temperature, and the oil cooling effect of the unit is affected. Firstly, a certain pressure difference is needed by common oil cooling equipment to enable the refrigerant to enter an oil cooler for heat exchange. However, for small units, the small units have a compact structure, so that a sufficient pressure difference cannot be realized to ensure the supply of the refrigerant in the oil cooling process. And secondly, the conventional oil cooling system adopts the refrigerant in the system to exchange heat, and the refrigerant in the condensing assembly is higher in temperature in the unit operation process, so that the temperature of the refrigerant entering the oil cooler is higher, and the expected heat exchange effect cannot be achieved. And because the unit operates the operating mode different under different water temperatures, the temperature and the pressure of refrigerant in the condensation subassembly are different, and refrigerant temperature is higher than under the conventional condition in certain abominable operating mode, and the cooling effect of frozen oil further weakens, and the oil temperature is relatively higher, influences unit safe and reliable operation and heat transfer effect.

Referring to fig. 1, an embodiment of the present utility model provides a heat exchange device 100, which includes a cooling assembly 10, wherein the cooling assembly 10 is used for cooling refrigerant oil discharged from a compressor 210 in an air conditioner. The cooling assembly 10 comprises a first heat exchange member 11 and a second heat exchange member 13. The first heat exchange component 11 is arranged on the flow pipeline of the frozen oil, and the second heat exchange component 13 is communicated with the first heat exchange component 11. The first heat exchange member 11 and the second heat exchange member 13 are filled with a cooling refrigerant, and the cooling refrigerant circulates between the first heat exchange member 11 and the second heat exchange member 13 and does not flow to the compressor 210.

The refrigeration oil is oil used for lubrication of various moving parts within the compressor 210, and may also be referred to as a lubricating oil. The temperature of the refrigerant oil discharged from the compressor 210 is relatively high, and the refrigerant oil is required to be cooled and then returned to the compressor 210, and it should be understood that, in order to achieve the discharge and the return of the refrigerant oil, the compressor 210 should have a discharge port for discharging the refrigerant oil and an inlet for returning the refrigerant oil. The compressor 210 is operative to compress a refrigerant for refrigerating and heat exchanging, and the refrigerant and the compressed refrigerant may be various refrigerants or other flowing media capable of performing heat exchanging, preferably a medium capable of performing phase change during heat exchanging, and taking away or releasing a large amount of heat during the phase change. The types of media selected for the refrigeration refrigerant and the cooling refrigerant can be the same or different.

Unlike the refrigerant, the cooling refrigerant does not enter the compressor 210, and thus does not participate in the refrigeration cycle of the air conditioner, but is used exclusively for cooling the refrigerant oil discharged from the compressor 210. Therefore, the cooling refrigerant and the cooling refrigerant flow independently, and do not flow. Specifically, the cooling refrigerant performs a cooling cycle on the frozen oil, and in the cycle process, the cooling refrigerant exchanges heat with the frozen oil in the first heat exchange component 11, takes away heat of the frozen oil, condenses in the second heat exchange component 13, and cools down, and releases heat.

The heat exchanger 100 has a cooling unit 10 for cooling the refrigerant oil, and the cooling medium in the cooling unit 10 is not taken from the high-temperature and high-pressure refrigerant generated by the compressor 210, but is a cooling medium that circulates independently. The cooling refrigerant does not enter the compressor 210, and does not need to participate in the refrigeration cycle of the air conditioner, compared with the refrigeration refrigerant, the pressure difference required by the cooling refrigerant for cooling the refrigeration oil is obviously reduced, the temperature of the cooling refrigerant is lower, and the cooling effect is better. In addition, the cooling refrigerant is less affected by the working condition of the air conditioner.

In this embodiment, the heat exchange device 100 is used in a water chiller, and the water chiller is specifically a screw water chiller. It will be appreciated that the present utility model can be used in other types of air conditioners for cooling the cooling oil to achieve the above effects, and is not particularly limited herein.

Further, the cooling assembly 10 further includes a first communication pipe 15 and a second communication pipe 17, and the first communication pipe 15 and the second communication pipe 17 are provided between the first heat exchange member 11 and the second heat exchange member 13. The cooling refrigerant flows from the first heat exchange member 11 to the second heat exchange member 13 through the first communication pipe 15, and flows from the second heat exchange member 13 to the first heat exchange member 11 through the second communication pipe 17. The first heat exchange member 11 is higher than the second heat exchange member 13 in the gravitational direction. The first communication pipe 15 is higher than the second communication pipe 17 in the gravity direction.

Through the two communicating pipes, the cooling refrigerant can circulate between the first heat exchange component 11 and the second heat exchange component 13, and the first heat exchange component 11 is communicated with the second heat exchange component 13 in a closed mode. The circulating power source of the cooling refrigerant can be a height difference and a temperature difference between the first heat exchange component 11 and the second heat exchange component 13, so that a self-force siphon is formed in the closed communication between the first heat exchange component 11 and the second heat exchange component 13. The cooling refrigerant may undergo a phase change during circulation, and may be a gaseous cooling refrigerant heated by cooling the refrigerant oil flowing through the first communication pipe 15, and may be a liquid cooling refrigerant cooled by condensation in the second heat exchange member 13 flowing through the second communication pipe 17.

In other embodiments, the cooling assembly 10 may be further provided with a driving device to actively drive the cooling refrigerant to circulate.

Further, the first heat exchanging part 11 and the second heat exchanging part 13 are provided with check valves 19, and the cooling refrigerant circulates therebetween in a single flow direction.

The check valve 19 can avoid the reverse flow of the cooling refrigerant, and ensure the orderly cooling circulation between the first heat exchange component 11 and the second heat exchange component 13. The check valve 19 may be provided on the first communication pipe 15 and/or the second communication pipe 17.

In some embodiments, the second heat exchange member 13 is higher than the first heat exchange member 11 in the direction of gravity.

By means of the height difference, the cooling refrigerant condensed and cooled by the second heat exchange component 13 can flow back to the first heat exchange component 11 under the driving of gravity. Thanks to the independent circulation of the cooling medium, the driving pressure difference is not required, so that the height difference between the first heat exchanging element 11 and the second heat exchanging element 13 is not required to be too large.

In some embodiments, the air conditioner further includes an oil return pipe 230, and the refrigerant oil discharged from the compressor 210 is returned to the compressor 210 through the oil return pipe 230. The first heat exchange member 11 is provided on the oil return pipe 230. In this way, the first heat exchange member 11 can exchange heat sufficiently with the high-temperature frozen oil discharged from the compressor 210 and flowing through the oil return pipe 230, thereby cooling it.

Further, the oil return pipe 230 includes an oil separator 231 and a pipe 233, wherein the oil separator 231 has an inlet, a first outlet and a second outlet, and is communicated with the compressor 210 through the inlet, and the oil separator 231 is used for separating the refrigerating oil discharged from the compressor 210 from the refrigerating refrigerant. The separated refrigerating oil and the separated refrigerating refrigerant are discharged through the first outlet and the second outlet respectively.

While the compressed refrigerant is discharged during the operation of the compressor 210, the refrigerant is discharged together with the refrigerant, that is, the refrigerant that needs to be returned to the compressor 210, it is understood that before the refrigerant is returned, the refrigerant is separated from the refrigerant by the oil separator 231, so that the refrigerant can be separately returned to the inlet of the compressor 210 through the pipe 233.

Specifically, the first heat exchange member 11 is disposed on the pipe 233, and the first heat exchange member 11 is located between the first outlet and the compressor 210 in the flow path of the refrigerant oil.

The first heat exchange component 11 may be disposed on the pipe 233 in a manner of being sleeved on the pipe 233, and indirectly exchanges heat through the pipe 233, or may be connected to the pipe 233, so that the refrigerating oil directly flows through the first heat exchange component 11, and at this time, the first heat exchange component 11 has two non-communicating chambers, one for circulating the refrigerating oil and the other for circulating the cooling refrigerant, and exchanges heat therebetween.

The pipe 233 is a pipe through which the refrigerant oil flows, and the first heat exchange member 11 cools the refrigerant oil discharged from the compressor 210 during the process of returning the refrigerant oil to the compressor 210, in other words, before the refrigerant oil returns to the compressor 210 again, the refrigerant oil must be cooled by the first heat exchange member 11 to ensure the stability of the operation of the compressor 210.

In some embodiments, the heat exchange device 100 further includes a condensing assembly 30, where the condensing assembly 30 includes a heat exchange tube including a first tube segment 31 and a second tube segment 33 that are isolated from each other. The first pipe section 31 serves as the second heat exchange member 13 for circulating a cooling refrigerant. The second pipe section 33 communicates with the compressor 210 and circulates the refrigerant discharged from the compressor 210. Specifically, the condensing unit 30 further includes heat sinks 35, and the heat sinks 35 are wrapped around the first tube section 31 and the second tube section 33.

The first tube section 31 and the second tube section 33 are not communicated with each other, so that the cooling refrigerant and the refrigerating refrigerant can be respectively condensed and cooled in two sections of different heat exchange tubes. The air conditioner is provided with a liquid storage tank, and the refrigerating refrigerant obtained by condensing the first pipe section 31 flows out of the first pipe section 31 and is stored in the liquid storage tank.

The first tube section 31 and the second tube section 33 are covered with the heat sink 35, which helps to increase the heat dissipation area and enhance the heat dissipation effect. It will be appreciated that the first pipe section 31 as the second heat exchange component 13 may be regarded as a part of pipe section which is cut off based on the original condenser, and the part of pipe section is independent and is specially used for condensing the cooling refrigerant after cooling and heat exchange with the refrigerating oil. Therefore, although the cooling device 100 has the independent second heat exchanging element 13, the whole air conditioner structure and arrangement are not significantly changed, and the original condition is fully utilized.

In other embodiments, the second heat exchange member 13 may also be a separate member from the condensing assembly 30, having separate fins 35, rather than being part of the condensing assembly 30, and the placement location is selected autonomously, not specifically limited herein.

Further, the separated refrigerant flows back to the compressor 210 through the first outlet of the oil separator 231 and the pipe 233, and the separated refrigerant flows into the second pipe section 33 through the second outlet of the oil separator 231, and the two refrigerant flows into the first heat exchange member 11 and the second pipe section 33 for cooling.

In some embodiments, the first heat exchange component 11 includes an oil heat exchange member 111 and a refrigerant heat exchange member 113, where the oil heat exchange member 111 is in communication with the oil return pipe 230 and provides for the flow of frozen oil. The refrigerant heat exchanging element 113 communicates with the second heat exchanging element 13 and allows the cooling refrigerant to flow therethrough. The refrigerant oil flowing through the oil heat exchange member 111 exchanges heat with the cooling refrigerant flowing through the refrigerant heat exchange member 113.

Specifically, the oil heat exchanging member 111 is connected to the pipe 233 of the oil return pipe 230, and the refrigerant oil flowing from the pipe 233 to the compressor 210 passes through the oil heat exchanging member 111. The two ends of the refrigerant heat exchanging member 113 are respectively communicated with the second heat exchanging member 13 through the first communicating pipe 15 and the second communicating pipe 17, and exchange heat with the refrigerant oil passing through the oil heat exchanging member 111 when the cooling refrigerant is cooled and circulated through the refrigerant heat exchanging member 113, so as to cool the cooling refrigerant.

In the heat exchange device 100, the high-temperature refrigerant generated during the compression operation of the compressor 210 is discharged together with the refrigerant oil and separated by the oil separator 231. The separated refrigerant enters the second pipe section 33 of the condensing assembly 30 for condensing and cooling, and the refrigerant oil enters the pipe 233 of the oil return pipe 230 for returning to the compressor 210. Because the temperature of the refrigerant oil discharged from the compressor 210 is high, the refrigerant oil must be cooled before returning to the compressor 210 in order to ensure that the compressor 210 operates stably. The first heat exchange component 11 of the heat exchange device 100 is disposed on the pipeline 233, the second heat exchange component 13 is a first pipe section 31 in the condensing assembly 30, and cooling refrigerant is filled in the first pipe section 31 and exchanges heat with the refrigerating oil at the first heat exchange component 11 to take away heat of the refrigerating oil, so as to achieve the effect of cooling. The cooling medium thus warmed up flows into the second pipe section 33 to condense and cool down, and can be used to continue cooling the refrigerant oil, thereby cooling the refrigerant oil continuously by the cooling cycle between the first heat exchange member 11 and the second pipe section 33. Because the cooling refrigerant circulates independently between the first heat exchange component 11 and the second pipe section 33, is not communicated with the compressor 210 and the first pipe section 31, and does not participate in the circulation of the compressor 210, the temperature of the cooling refrigerant is lower than that of the cooling refrigerant in the first pipe section 31, cooling of the cooling refrigerant is facilitated, and the pressure is smaller than that of the cooling refrigerant in the first pipe section 31, so that the cooling refrigerant is more convenient to drive.

In an embodiment of the present utility model, an air conditioner is further provided, including the heat exchange device 100 described above.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
