Problems solved by technology

Additionally, if figure 2 As shown, in mass production, in order to ensure that the connection between the capillary tube 10 and the evaporator tube 30 will not be blocked by welding, the connecting tube 20 must have a section of cantilever section 20a extending into the evaporator. When working, an eddy current is formed around the cantilever section 20a area, causing greater noise. Similarly, when the capillary 10 is connected to the connecting pipe 20, there is also the problem of increased noise due to the eddy current area caused by the cantilever section

Embodiment Construction

[0020] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0021] Such as image 3 with Figure 4 As shown, a capillary and evaporator connecting device according to the present invention is used to connect the capillary 10 and the evaporator tube 30, including a capillary connecting part 21, an evaporator connecting part 23 and a transition part 22 between the two, the capillary The connecting part 21 comprises a straight pipe part 211 connected with the transition part 22 and an expansion part 212 connected with the straight pipe part 211; Steps are formed between them, and the inner diameter of the expansion part 212 is equal to the outer diameter of the capillary 10 . When the capillary 10 is inserted into the expansion part 211, the step restricts the capillary 10 from being too long, preventing the capillary 10 from forming a cantilever section inside the connecting device 20, thereby preventing the refrig...

Abstract

The invention provides a capillary tube and an evaporator connecting device and a refrigerating device with same. The capillary tube and the evaporator connecting device, used for connecting the capillary tube with the evaporator, comprises a capillary tube connecting portion, an evaporator connecting portion and a transition portion between the two. The capillary tube connecting portion comprises a straight tube portion and an expansion portion, wherein the straight tube portion is connected with the transition portion, the expansion portion is connected with the straight tube portion, the inner diameter of the straight tube portion is smaller than the outer diameter of the capillary tube, a step is formed between the expansion portion and the straight tube portion, and the inner diameter of the expansion portion is equal to the outer diameter of the capillary tube. The refrigerating device comprises the capillary tube, the evaporator and the connecting device of the capillary tube and the evaporator. The refrigerating fluid can be smoothly transited from the smaller inner diameter of the capillary tube to the larger inner diameter of the evaporator tube, expansion noises caused by sudden change of the inner diameter of the tube and the fluid noises caused by block to the welding point can be avoided, thus the refrigerating device can work quietly.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to a capillary tube and evaporator connection device and a refrigeration device having the same. Background technique [0002] A refrigeration device is a heat preservation device that brings low temperature through a refrigeration cycle system. It mainly relies on the state change of the refrigerant to take away the heat inside the device, so as to maintain the set low temperature state to store food. [0003] A general refrigeration cycle system includes a compressor, a condenser, a filter drier, a capillary tube, and an evaporator. The evaporator uses the phase change of the refrigerant to take away heat to generate a low-temperature external environment; the compressor compresses the refrigerant discharged from the evaporator; the condenser cools the compressed refrigerant; the capillary tube throttles the compressed medium After pressure treatment, it is discharged into the evaporato...
