Optionally, the capillary inner channel 110 and the external channels 120 disposed at two ends of the capillary inner channel 110 are both located in the tube 100, and the external channels 120 disposed at two ends of the capillary inner channel 110 are both correspondingly disposed in two end regions of the tube 100. Thus, the tube body 100 can protect the capillary inner channel 110 and the external channel 120 inside the tube body, and the external channel 120 is disposed inside the two end regions of the tube body 100, so that the tube body 100 is conveniently connected with other external pipelines 200 through the external channel 120, and the outer side wall of the tube body 100 can be used for protecting the connection between the external channel 120 and the external pipeline 200, thereby improving the stability of the tube body 100 after being connected externally.

Optionally, the tube 100 is made of red copper. Like this, red copper is industrial pure copper, and its plasticity and corrosion resistance are all better, still have good welding performance, therefore body 100 adopts red copper material to make, and the tensile shaping of body 100 and follow-up and external pipeline 200's assembly welding are convenient for in the production and processing process, make body 100's environmental suitability stronger when being used for air conditioner refrigeration work, prolong its life.

Alternatively, the tubular body 100 is a one-piece cast structure. Thus, the pipe body 100 is produced by adopting the production process of integral casting, the integral casting formed pipe body 100 has no welding spot, the structural strength is higher, the stability is stronger when the pipe body is externally connected, and the service life is prolonged.

Optionally, the tubular body 100 is of unitary forge formed construction. Thus, the pipe body 100 is produced by adopting an integrated forging and pressing production process, the integrally forged and pressed pipe body 100 is stronger in toughness and higher in tensile strength, and can adapt to various assembly environments when the pipe body 100 is assembled with the external pipeline 200, and the service life is longer.

It can be understood that the processing length of the tube 100 can be determined according to the processing requirement, because the inner capillary flow channel 110 and the outer capillary flow channel 120 are disposed inside the tube 100, and the inner capillary flow channel 110 can function as a capillary tube in the tube 100, when the tube 100 is connected to a refrigeration system of an air conditioner externally, the inner capillary flow channel 110 can be used to throttle and depressurize the refrigerant flowing through, because the length of the capillary tube in the refrigeration system is related to the refrigeration capacity of the refrigeration system and the inner diameter of the capillary tube, when the tube 100 is manufactured, the length of the inner capillary flow channel 110 in the tube 100 to be processed can be determined according to the refrigeration capacity of the refrigeration system to which the tube 100 needs to be connected and the inner diameter of the inner capillary tube 110 to be processed, and then the length of the outer external flow channel 120 for the tube 100 to be connected externally, thereby determining the total length of the tube 100.

Optionally, the inner diameter of the capillary inner channel 110 is greater than 1.2mm and less than or equal to 2 mm. Thus, when the pipe body 100 is connected to a refrigeration system, the capillary inner flow passage 110 performs the same throttling function as a capillary tube, the high-pressure refrigerant flowing out of a condenser is throttled by the capillary inner flow passage 110, the refrigerant is throttled and depressurized and then flows into an evaporator for evaporation, the inner diameter of the capillary inner flow passage 110 is large in size in consideration of the throttling effect of the refrigerant, so that the evaporation temperature of the evaporator is affected, when the inner diameter of the capillary inner flow passage 110 is less than or equal to 1.2mm, the inner diameter of the capillary inner flow passage 110 is small, and at this time, although the pressure difference between the condenser side and the evaporator side is large, the refrigerant flow in the capillary inner flow passage 110 is small, so that the pressure on the condenser side is high, and the refrigeration system is damaged, when the inner diameter of the capillary inner flow passage 110 is greater than 2mm, although the flow area of the capillary inner flow passage 110 is increased at this time, but the throttling and depressurizing effect is poor, the pressure difference between the condenser side and the evaporator side is small, the flow of the refrigerant is reduced, and the evaporation temperature of the evaporator is influenced, so that the heat exchange effect is influenced, the inner diameter of the capillary inner flow passage 110 is larger than 1.2mm and smaller than or equal to 2mm, the capillary inner flow passage 110 can play a good throttling and pressure reducing effect, the condenser side and the evaporator side of the capillary inner flow passage 110 generate proper pressure difference, the flow of the refrigerant flowing into the evaporator can be ensured, the evaporation effect in the evaporator is ensured, and the evaporation heat exchange effect is improved.

Optionally, the inner diameter of the capillary inner channel 110 is greater than or equal to 1.8mm and less than or equal to 2 mm. Thus, because the capillary inner flow channel 110 disposed in the tube body 100 is connected to a refrigeration system to achieve the same throttling and pressure reducing effect as that of a capillary tube in the refrigeration system, when the inner diameter of the capillary inner flow channel 110 is greater than 1.2mm and less than 1.8mm, the capillary inner flow channel 110 can be applied to a refrigeration system of a small and medium-sized refrigeration device, but the limitation is large, and the capillary inner flow channel 110 is bound by the inner diameter of the capillary inner flow channel 110, and can only be applied to some refrigeration systems with little refrigeration requirement, and when the inner diameter of the capillary inner flow channel 110 is greater than 2mm, the flow area of the capillary inner flow channel 110 is increased, but the throttling and pressure reducing effect is poor, so that the pressure difference between the condenser side and the evaporator side is small, the flow of the refrigerant is reduced, the evaporation temperature of the evaporator is affected, and the heat exchange effect is affected, so that the inner diameter of the capillary inner flow channel 110 is greater than or equal to 1.8mm, and is less than or equal to 2mm, make the capillary internal flow path 110 can play better throttle depressurization effect, produce suitable pressure differential in the condenser side and evaporator side of the capillary internal flow path 110, can guarantee the flowrate of refrigerant flowing into the evaporator, thus has guaranteed the evaporation effect in the evaporator, has improved the evaporation heat transfer effect, make the application scope of this body 100 in the refrigerating system more extensive.

Thus, the pipe body 100 is assembled with the external pipe 200 through the external flow channel 120 at both ends thereof, and is connected to the refrigeration system for use, when the internal diameter of the external flow channel 120 is less than or equal to 3mm, the internal diameter of the external flow channel 120 is smaller, and is not easy to be matched with the external pipe 200 in the refrigeration system to complete assembly, when the internal diameter of the external flow channel 120 is greater than 4.76mm, the external pipe 200 in the refrigeration system is inserted into the external flow channel 120 to be assembled with the pipe body 100, but after assembly, the gap between the outer wall of the external pipe 200 and the inner wall of the external flow channel 120 is larger, and after welding, welding slag excessively extends into the external flow channel 120, and blocks the capillary internal flow channel 110, and reduces the pressure reduction effect of the capillary internal flow channel 110, so that the internal diameter of the external flow channel 120 is greater than 3mm and less than or equal to 4.76mm, and the pipe body 100 can be better connected to the refrigeration system through the external flow channel 120, and improves the assembling strength of the pipe body 100 after assembly, and prolongs the service life thereof.

Optionally, the inner diameter of the external flow channel 120 is greater than or equal to 4mm, and less than or equal to 4.76 mm. Thus, since the tube body 100 is assembled with the external pipe 200 in the refrigeration system through the external flow channel 120 located at both ends thereof, and is connected into the refrigeration system, so that the capillary internal flow channel 110 in the tube body 100 can throttle and reduce the pressure of the refrigerant flowing through the tube body 100, but in case that the internal diameter of the external flow channel 120 is less than 4mm, the external pipe 200 is not easily inserted into the external flow channel 120 to be assembled with the tube body 100 due to the limitation of the external diameter of the external pipe 200, even if the welding seam cannot enter the gap between the external pipe 200 and the external flow channel 120 after assembly, the welding seam can only be performed at the interface of the external flow channel 120, resulting in low assembly strength of the tube body 100, in case that the internal diameter of the external flow channel 120 is greater than 4.76mm, the external pipe 200 in the refrigeration system is inserted into the external flow channel 120 to be assembled with the tube body 100, but the gap between the outer wall of the external pipe 200 and the inner wall of the external flow channel 120 is large after assembly, after welding, welding slag can excessively go deep into the external flow channel 120, so that the internal flow channel 110 is blocked, the throttling and pressure reducing effects of the internal flow channel 110 are reduced, the internal diameter of the external flow channel 120 is larger than or equal to 4mm and smaller than or equal to 4.76mm, the pipe body 100 can be better connected into a refrigeration system through the external flow channel 120, the welding strength between the assembled pipe body 100 and the external pipeline 200 is improved, and the service life of the assembled pipe body is prolonged.

Optionally, the inner diameter of the circumscribed flow passage 120 is equal to 4.5 mm. Thus, under the condition that the inner diameter of the external flow passage 120 is equal to 4.5mm, the external flow passage 120 can be better assembled with the external pipeline 200 in the refrigeration system, the welding strength between the assembled pipe body 100 and the external pipeline 200 is ensured, the service life of the pipe body 100 in the refrigeration system is prolonged, and the service life of the refrigeration system is prolonged.
