The invention relates to the field of refrigeration equipment, namely, to designs of evaporative units cooling units of refrigerators and freezers household purpose.Known for the design of the evaporative unit refrigeration unit that contains one United capillary tube, evaporator coil, decimater and the suction tube (French patent N 1355116 F 25 B from 03.02.1964 year ). One end of the evaporator coil in this arrangement, zakluchaetsja and evaporator coil for its plugged end.The application of the technical solutions in multiple leaf-tube evaporator units is impossible because of the much greater length of the evaporator coil as compared to the required length of the capillary tube.Selected as a prototype design of the evaporative unit refrigeration unit contains consistently United capillary tube, the coil of a multiple leaf-and-tube evaporator, each section of which consists of a curved aluminum tube, tacked to the metal sheet, decimates and the suction tube, made of aluminum tubes (Lepew.D. And Repair of household refrigerators. The Handbook. M Legprombytizdat, 1989. S. 162, Fig.68).Capillary tube on a certain site goes inside the suction tube. Before the junction of the suction tube with datepalm capillary tube goes out and connects with the inlet of the evaporator coil. The connection of the capillary tube with the inlet of the evaporator coil and output it from the suction tube by using bimetallic pipes consisting of copper and aluminum tubes, interconnected, for example, by welding.The use of evaporative unit bimeta assocname coating or plastic tubes, put on the joints, and reduces the reliability of the design because of the emergence of additional joints.To simplify the design of the evaporative unit, increase its reliability and efficiency of cooling of the refrigerant flowing from the capillary tube into the evaporator task, which is aimed at solving the claimed invention.Declare evaporative unit refrigeration unit contains consistently United capillary tube, evaporator coil, decimater and the suction tube. To doxypalu, made of aluminum tube, joining the inlet and outlet of the evaporator coil, suction tube, passing inside the capillary tube, which is inside decimates is connected to the inlet side of evaporator coil.Diagram of the evaporative unit shown in Fig.1; Fig.2 incision decimates with a plot of the capillary tube retainers along a helical line; Fig.3 - cut decimates with a plot of the capillary tube that is wrapped around the inlet pipe of the evaporator coil.Evaporative unit refrigeration unit contains consistently United capillary tube 1, the evaporator coil 2 made of aluminum tube, decimater 3 and alytes. To the nozzle 5 of the evaporator coil 2 is connected capillary tube 1 passing inside the suction tube 4 and decimates 3. The pipe 5 is made of aluminum tube and the evaporator coil 2, or bimetal consisting of copper and aluminum tubes, interconnected, for example, by welding.The inner diameter of the pipe 5 at the site of his connection with the capillary tube 1 is made under its outer size.The connection of the capillary tube 1 with the pipe 5 is carried out by compression of the socket around the capillary tube, if the tube is made of aluminum tube, or by soldering, if the pipe is made of bimetal.Finding the intersection of the capillary tube 1 with a pipe 5 inside decimates 3 increases its mechanical strength, reliability, eliminates the need to protect the joint from anticorrosion.To improve cooling efficiency of the refrigerant flowing from the capillary tube 1 in the evaporator coil 2, the capillary tube 1 inside decimates 3 before connection pipe 5 has an area of 6 stranded along a helical line, or plot 7 is wound on the pipe 5 of the evaporator coil 2.During operation of the refrigeration unit liquid refrigerant adagent boils and takes away the heat from the evaporator. The refrigerant, not had time to evaporate in the evaporator coil 2, enters decimater 3, where fully docial. From decimates 3 pairs of refrigerant on the suction tube 4 are received in the motor-compressor refrigeration unit.The use of the invention in the construction of the evaporative unit refrigeration unit allows to simplify the construction, increase its reliability and efficiency of the cooling of the refrigerant entering the evaporator of the capillary tube. 1.
