Embodiment.
Fig. 1 (a) illustrates the principle of refrigerant loop.The liquid refrigerant that discharges from compressor 11 flow through condenser 12, expansion valve 13 and evaporimeter 14 return compressor 11 then.Expansion valve 13 is electric expansion valves.As shown in Figure 2, expansion valve 13 comprises a power-jdriven gear, and it is a solenoid coil 132 in this embodiment, also has a valve body 133.When electric current being provided for solenoid coil 132, solenoid coil 132 mobile valves 133.Valve body 133 direction towards closed valve opening 131 under the effect of spring 134 is moved.Whether valve opening 131 is had electric current to flow through solenoid coil 132 by valve body 133 bases opens and closes.Electric current then is according to the unlatching of compressor and stops to offer solenoid coil 132.
Fig. 3 (a) pipeline 17 of first vary in diameter that drawn, Fig. 3 (b) pipeline 18 of second vary in diameter that drawn.First and second pipeline the 17, the 18th are made of metal, such as copper, steel, brass, stainless steel and aluminium.
The pipeline 17 of first vary in diameter comprises a major part 171 with minimum diameter, the reinforcing section 172,173 that diameter is bigger than major part 171, and diameter is greater than the connector part 174,175 of reinforcing section 172,173.The internal diameter of reinforcing section 172,173 is greater than the internal diameter of major part 171.The internal diameter of connector part 174,175 is greater than the internal diameter of reinforcing section 172,173.In major part 171, between any phase adjacency pair in reinforcing section 172,173 and the connector part 174,175 all without any joint.That is to say that the pipeline 17 of first vary in diameter is integrally formed.Tapered intermediate portion 176 is between major part 171 and reinforcing section 172,173.The internal diameter of each transition portion 176 and external diameter increase on the direction of the reinforcing section 172,173 of correspondence gradually in major part 171.
A tapering transition section 177 is between a connector part 174,175 of each reinforcing section 172,173 and correspondence.The internal diameter of each changeover portion 177 and external diameter increase on the direction of a connector part 174,175 of correspondence gradually at reinforcing section 172,173.
The pipeline 18 of second vary in diameter comprises a major part 181 with minimum diameter, and diameter is greater than a reinforcing section 182 of the diameter of major part 181, and diameter is greater than the connector part 183,184 of the diameter of reinforcing section 182.The internal diameter of reinforcing section 182 is greater than the internal diameter of major part 181.The internal diameter of connector part 183,184 is greater than the internal diameter of reinforcing section 182.Between any a pair of adjacent part of major part 181, reinforcing section 182 and connector part 183,184 without any joint.That is to say that the pipeline 18 of second vary in diameter is integrally formed.Between tapered intermediate portion 186 each part in major part 181 and 182,183 these two parts.The internal diameter of transition portion 186 and external diameter increase on the direction of counterpart 182,183 gradually in major part 181.A tapered intermediate portion 187 is between reinforcing section 182 and connector part 184.The external diameter of transition portion 187 and internal diameter increase on the direction of connector part 184 gradually at reinforcing section 182.
Major part 171,181 with minimum diameter generally all is called capillary.The external diameter of major part 171,181 comprises this two values between 2.4 millimeters and 16.0 millimeters.The external diameter of the reinforcing section 173,174,182,183 of intermediate diameters comprises this two values between 3.0 and 15.99 millimeters.The external diameter of major diameter connector part 174,175,184 comprises this two values between 4.76 millimeters to 16.0 millimeters.The internal diameter of major part 171,181 comprises this two values between 0.1 millimeter to 14.4 millimeters.The internal diameter of the reinforcing section 172,173,182,183 of intermediate diameters comprises this two values between 0.8 millimeter to 14.8 millimeters.The internal diameter of large diameter connector part 174,175,184 comprises this two values between 2.4 millimeters to 14.8 millimeters.The thickness of every pipe comprises this two values between 0.6 millimeter to 1.2 millimeters.The maximum length of major part 171,181 is 700 millimeters.The maximum length of reinforcing section 172,173,182 is 150 millimeters.The maximum length of connector part 174,175,184 is 300 millimeters.The value that the internal diameter of major part 171,181 is not limited to list above, but can be less than 0.1 millimeter.
As Fig. 1 (a) with shown in 2, the pipeline 17 of first vary in diameter all becomes reservation shape according to the shape of refrigerant loop with pipeline 17,18 location bendings with respect to expansion valve 13 with the pipeline 18 of second vary in diameter.Connector part 174 is fit into the refrigerant inlet 15 of expansion valve 13.Scolder 19 is applied to the joint between the periphery of the perforate of refrigerant inlet 15 and connector part 174.In this integrality, the connector part 175 of the pipeline 17 of first vary in diameter is connected with the pipeline 101 of condenser 12.
The connector part 183 of the pipeline 18 of second vary in diameter is fit into the refrigerant outlet 16 of expansion valve 13.Scolder 20 is applied to the joint between the periphery of the perforate of refrigerant outlet 16 and connector part 183.The connector part 184 of the pipeline 18 of second vary in diameter connects with the pipeline 102 that has been connected evaporimeter 14.Reinforcing section 172,173,182 increases the bonding strength of connector part 174,175,184.The vibration and the noise that produce when reinforcing section 172,173,182 also suppresses flow of refrigerant.
The refrigerant gas that comes out from compressor 11 device 12 that is condensed siphons away heat, thus liquefaction.The cold-producing medium of liquefaction is atomized when the major part 171 of the pipeline 17 of first vary in diameter flows to reinforcing section 172 and connector part 174.The cold-producing medium of atomizing is sent to expansion valve 13 and evaporimeter 14.The cold-producing medium of delivering to evaporimeter 14 absorbs evaporimeter 14 heat on every side, makes the cooling on every side of evaporimeter 14.In the time of by evaporimeter 14, cold-producing medium returns compressor 11.
First embodiment has the following advantages.
(1) pipeline 17 that comprises first vary in diameter of 171 to 175 of different diameter parts is formed by whole, without any welding point.Equally, comprise that the pipeline 18 of second vary in diameter of 181 to 184 of different diameter parts is also formed by integral body, without any welding point.That is to say, soldering include only vary in diameter pipeline 17,18 connector part 174,183 and expansion valve 13 refrigerant outlet 16 and be connected to the scolder 19,20 of refrigerant inlet 15.Therefore, with be installed in before the refrigerant loop, the pipe section of different-diameter is compared by the situation that welding forms a pipe, adopts the refrigerant loop of global formation vary in diameter pipeline 17,18 to reduce because the possibility that weld defect causes cold-producing medium to leak.
The pipeline 17 of (2) first vary in diameter is connected with refrigerant inlet 15, and the pipeline 18 of second vary in diameter is connected with outlet 16.This structure makes the high-pressure liquefaction cold-producing medium flow through lentamente, thereby reduces the resistance of pipeline.Can reduce the vibrations noise that flow of refrigerant produces like this.
(3) in order to dwindle the size of refrigerant loop, the major part 171,181 with minimum diameter is bent.If adopt the integrally formed prior art pipeline 1 that do not have shown in Figure 16, small diameter portion must be come bending in this manner so, and this mode can guarantee that the joint between the different-diameter pipeline part is without prejudice.Be not that integrally formed pipeline is compared, be the bend mode of smallest diameter portion without any the advantage of the pipeline 17,18 of the vary in diameter of joint.That is to say, utilize the present invention just can select the curved patterns of the pipeline 17,18 of vary in diameter neatly.Therefore, with respect to the pipeline that is not global formation, the size that the pipeline 17,18 of the vary in diameter of employing global formation can fully dwindle refrigerant loop.
