Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims priority under 35 U.S.C. .sctn. 119(b) to Chinese Application No. 201910403033.3, filed on May 15, 2019, the disclosure of which is incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION

[0002] The present invention relates to the field of air conditioning technologies, and in particular, to an adaptive condensing device for a dual-loop heat pipe air conditioner.

[0003] A condenser is a component of a refrigeration system, and can convert gas or vapor into liquid, and quickly transfer heat in pipes to air near the pipes. The entire process is a heat release process. V-shaped condensers are common on the market, are generally air-cooled, and perform refrigeration by using forced convection air. Air is driven by a fan and is forced to circulate and flows horizontally through a finned tube to take away heat released by a refrigerant. Finned tubes on left and right sides of the V-shaped condenser are connected through upper and lower gathering tubes. The vapor gathering tube is above the liquid gathering tube. The finned tubes on the two sides play a condensation role together. An applicant applied for a Chinese patent with a publication number CN206439954U on Dec. 29, 2016, and disclosed DUAL-LOOP AIR CONDITIONER INTEGRATING WATER-COOLING AND HEAT PIPE AIR-COOLING FOR ROOM REFRIGERATION. When implementing the Chinese patent, the applicant found that an indoor unit requires a compressor evaporator and a heat pipe evaporator, and an outdoor unit includes a water-cooled condenser and an air-cooled condenser. That is, to make a compressor perform refrigeration under a working condition and a heat pipe perform refrigeration under a working condition, two condensers need to be configured, thereby resulting in many components, complicated installation, a large floor area, and high costs.

BRIEF SUMMARY OF THE INVENTION

[0004] An objective of the present invention is to provide an adaptive condensing device for a dual-loop heat pipe air conditioner, to make a compressor perform refrigeration under a working condition and a heat pipe perform refrigeration under a working condition.

[0005] The foregoing objective of the present invention is implemented by using the following technical solution: An adaptive condensing device for a dual-loop heat pipe air conditioner is provided, including a condenser body. A first electric shutter and a compressor condensing heat exchanger are disposed on one side of the condenser body, a second electric shutter and a heat pipe condensing heat exchange micro-channel are disposed on the other side of the condenser body, and a fan is disposed on the top of the condenser body.

[0006] In the foregoing technical solution, the dual-loop heat pipe air conditioner includes two refrigeration systems. One is a compressor system, including a compressor evaporator, a compressor, and an expansion valve. The other is a heat pipe system, including a heat pipe evaporator and a heat pipeline. During use of the adaptive condensing device for a dual-loop heat pipe air conditioner in this application, an upper end of the compressor condensing heat exchanger is connected to the compressor through the pipeline, and a lower end is connected to an indoor unit through the pipeline. One end of the heat pipe condensing heat exchange micro-channel is connected to the heat pipeline, and the other end is connected to the indoor unit.

[0007] When a compressor performs refrigeration under a working condition, the fan is started, the second electric shutter is closed, the first electric shutter is opened, a high-temperature and high-pressure refrigerant enters the compressor condensing heat exchanger from the indoor unit through a copper tube, and cool air is driven by the fan to pass through the first electric shutter to exchange heat with the compressor condensing heat exchanger, and a low-temperature and low-pressure refrigerant is then transported back to the indoor unit through the copper tube.

[0008] When a heat pipe performs refrigeration under a working condition, the fan is started, the first electric shutter is closed, the second electric shutter is opened, a high-temperature gaseous refrigerant enters the heat pipe condensing heat exchange micro-channel from the indoor unit through a copper tube, and cool air is driven by the fan to pass through the second electric shutter to exchange heat with the heat pipe condensing heat exchange micro-channel, and a low-temperature gaseous refrigerant is then transported back to the indoor unit through the copper tube.

[0009] The adaptive condensing device for a dual-loop heat pipe air conditioner can make the compressor the heat pipe perform refrigeration under the working condition, and there is no need to configure two condensers, thereby reducing occupied space, facilitating installation and maintenance, and reducing costs.

[0010] The present invention is further provided as follows: The compressor condensing heat exchanger is located on a side of the first electric shutter close to an interior of the condenser body.

[0011] The present invention is further provided as follows: The heat pipe condensing heat exchange micro-channel is located on a side of the second electric shutter close to an interior of the condenser body.

[0012] The present invention is further provided as follows: The compressor condensing heat exchanger is a copper-tube aluminum fin.

[0013] The present invention is further provided as follows: A cavity is formed inside the condenser body, and an air inlet of the fan is located in the cavity.

[0014] The present invention is further provided as follows: A section of the condenser body is V-shaped.

[0015] The present invention has the following beneficial effects: When the compressor performs refrigeration under the working condition, the fan is started, the second electric shutter is closed, and the first electric shutter is opened, and cool air is driven by the fan to pass through the first electric shutter to exchange heat with the compressor condensing heat exchanger. When the heat pipe performs refrigeration under the working condition, the fan is started, the first electric shutter is closed, the second electric shutter is opened, and cool air is driven by the fan to pass through the second electric shutter to exchange heat with the heat pipe condensing heat exchange micro-channel. In this way, the adaptive condensing device for a dual-loop heat pipe air conditioner can make the compressor and the heat pipe perform refrigeration under the working condition, and there is no need to configure two condensers, thereby reducing occupied space, facilitating installation and maintenance, and reducing costs.
