Description
Technical field
The present invention relates to refrigerating field, in particular to a kind of capillary tube and vaporizer attachment means and the refrigeration dress with it
Put.
Background technology
Refrigerating plant is a kind of attemperator being brought low temperature by cooling cycle system, and it relies primarily on refrigerant condition change band
Heat within walking apparatus, thus maintain the low temperature state of setting to store food materials.
General cooling cycle system includes compressor, condenser, device for drying and filtering, capillary tube and vaporizer.Vaporizer utilizes
Heat is taken away in the change of the phase of cold-producing medium, produces the external environment condition of low temperature；The cold-producing medium that vaporizer is discharged is compressed by compressor；
The cold-producing medium of compression is carried out cooling process by condenser；After compressed media is carried out reducing pressure by regulating flow process by capillary tube, it is discharged to vaporizer
In.
As it is shown in figure 1, the structure of attachment means between capillary tube and vaporizer is as it can be seen, evaporator section in prior art
It is made up of, between evaporator tube 30 and capillary tube 10 with playing fin 40 two parts increasing heat exchange area evaporator tube 30
Being attached by connecting tube 20, cold-producing medium flows to evaporator tube 30 from capillary tube 10 through connecting tube 20, can from Fig. 1
Going out, the diameter of capillary tube 10 is the narrowest, and the diameter of evaporator tube 30 is the most much bigger, in order to both be connected
Come, the coupling part between coupling part and connecting tube 20 and capillary tube 10 between evaporator tube 30 and connecting tube 20
There is the sudden change of pipe diameter, and with the presence of solder joint.When cold-producing medium flows through this sudden change at two with the velocity of sound, especially in sudden change
Bigger evaporator tube 30 and the transition portion of connecting tube 20, the cold-producing medium of low-temp low-pressure causes vibration because expanding shock duct wall
The noise produced can be very big, and because the existence of solder joint, the noise that cold-producing medium constricted flow produces is also to whole refrigerating plant
Quiet operation have the biggest impact.It addition, as in figure 2 it is shown, in production in enormous quantities, in order to ensure capillary tube 10 with steam
The connection sending out device pipe 30 does not occur weldering stifled, and connecting tube 20 must have one section of cantilever segment 20a in stretching into vaporizer, and during work, this hangs
Form vortex around arm section 20a, cause bigger noise, equally, capillary tube 10 there is also when connecting with connecting tube 20 as by
Vortex is caused and the problem that makes noise increase in cantilever segment.
Summary of the invention

Detailed description of the invention
Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As shown in Figure 3 and Figure 4, according to a kind of capillary tube and the vaporizer attachment means of the present invention, it is used for connecting capillary tube 10 He
Evaporator tube 30, including capillary tube connecting portion 21, vaporizer connecting portion 23 and transition part 22 positioned there between, capillary
Pipe jointing part 21 includes the straight sections 211 being connected with transition part 22 and the enlarged portion 212 being connected with straight sections 211；Straight tube
The internal diameter in portion 211, less than the external diameter of capillary tube 10, forms step, and enlarged portion 212 between enlarged portion 212 and straight sections 211
Internal diameter equal to the external diameter of capillary tube 10.When capillary tube 10 inserts enlarged portion 211, step limits capillary tube 10 to be goed deep into
Long, prevent capillary tube 10 to be internally formed cantilever segment in attachment means 20, thus stopped cold-producing medium around cantilever segment, caused whirlpool
Stream, reduces noise effectively.
The internal diameter of straight sections 211 is more than or equal to the internal diameter of capillary tube 10, thus ensures between straight sections 211 and enlarged portion 212
While can forming step, it is not result in that again step is excessive, so that after attachment means 20 is connected with capillary tube 10, at platform
At rank, cold-producing medium is formed and stop.
The tapered structure of transition part 22, the vaporizer that diameter change gradually expands to be relatively large in diameter from less straight sections 211 connects
Portion 23, thus prevent the sudden change of caliber, it is to avoid pipe diameter sudden change causes the cold-producing medium to expand noise.
Preferably, the external diameter of vaporizer connecting portion 23 is equal to the internal diameter of evaporator tube 30, vaporizer connecting portion 23 and evaporator tube
During 30 connection, the change of internal diameter of the pipeline is only vaporizer connecting portion 23 wall thickness, changes less, and it is less, separately that cold-producing medium expands noise
Outward, the external diameter of vaporizer connecting portion 23 is equal to evaporator tube 30 internal diameter, when preventing attachment means 20 to be connected with evaporator tube 30
Form cantilever segment, stop cold-producing medium around cantilever segment, cause eddy current, thus reduce noise.
According to the attachment means of the present invention, cold-producing medium is when attachment means internal flow, and internal diameter change mainly includes three parts, logical
Cross transition part 22 and change to the larger interior diameter of evaporator tube 30 smoothly from the less internal diameter of capillary tube 10, it is preferable that the present invention
Attachment means use integral forming process manufacture so that three portion connection do not have solder joint or other stop, three
Dividing and smoothly transit at diameter change, cold-producing medium is hindered the flow noise caused by the solder joint completely eliminating three portion connection.More
Preferably, attachment means uses drawing process to generate, convenient for production, technical maturity.
As it is shown in figure 5, curve L1 represents that the using effect of attachment means of the prior art, curve L2 represent the company of the present invention
The using effect of connection device, by the contrast of L1 and L2, uses the attachment means of the present invention can be effectively reduced frequency
At the noise of 700～about 1000Hz.
The present invention additionally provides a kind of refrigerating plant, including capillary tube 10 and evaporator tube 30, also include aforesaid capillary tube and
Vaporizer attachment means 20, attachment means 20 connects capillary tube 10 and evaporator tube 30, make the internal diameter of refrigerant flow channel from
The less internal diameter smooth transition of capillary tube 10 is to the larger interior diameter of evaporator tube 30, it is to avoid pipe diameter suddenlys change the expansion caused
Noise and solder joint hinder the flow noise caused so that refrigerating plant quietly runs.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect:
Capillary tube according to the present invention and vaporizer attachment means and have its refrigerating plant, make the internal diameter of refrigerant flow channel
Larger interior diameter from the less internal diameter smooth transition of capillary tube to evaporator tube, it is to avoid pipe diameter suddenlys change the expansion noise caused
The flow noise caused is hindered so that refrigerating plant quietly runs with solder joint.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for those skilled in the art
For, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of being made, etc.
With replacement, improvement etc., should be included within the scope of the present invention.
