The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.It should be noted that hereinafter only the utility model feature unlike the prior art to be described,, just do not given unnecessary details here for the technical characterictic that can find in the prior art.
At first with reference to Fig. 1, show the structural representation that has according to the heat exchanger of the bobbin carriage device of the utility model preferred embodiment.The part that circular I among Fig. 1 indicated is installed in cold-producing medium and enters between pipe and the heat exchanger tube for the bobbin carriage device that is used to heat exchanger assignment system cryogen according to the utility model preferred embodiment, this device.
Below with reference to the concrete structure of introducing according to the bobbin carriage device of the utility model preferred embodiment of Fig. 2.This bobbin carriage device mainly comprises: body, constitute by horizontally disposed cylindrical tube 2, and the left end of this cylindrical shell 2 (i.e. first end) is a cover plate 3, and its right-hand member 10 is openend (heat exchanger tube 7 sealings are installed on this openend), and the inside of this cylindrical shell 2 has formed chamber 8; Blast pipe 1 is arranged on upper part of body; Baffle plate 4 (referring to Fig. 3), the disk that has breach for the lower end, the periphery of this baffle plate 4 engages with the inwall of cylindrical shell 2, thereby chamber 8 is divided into upper isolation and two parts of bottom connection, is respectively the right side part (being second portion) that enters pipe 5 left part that communicate (being first) and communicate with cold-producing medium with heat exchanger tube 7; And filter assemblies 6 (referring to Fig. 5 and Fig. 6), horizontally disposed between the lower end of cover plate 3 and baffle plate 4, left part is divided into two spaces that are separated by up and down, and this filter assemblies 6 comprises two layers of support board 11 up and down and is clipped in screen pack 12 between them that this screen pack material is 1Cr18Ni9Ti.In addition, preferably, filter assemblies 6 is soldered to cover plate 3 and baffle plate 4.
For ease of understanding, the course of work and the principle of bobbin carriage device of the present utility model are simply introduced.The refrigerant air-liquid mixture enters pipe 5 left part that enter chamber 8 by cold-producing medium, because baffle plate 4 is in tilted layout, make refrigerant mixture upwards distribute, because the space of left part is enough big, refrigerant mixture after distributing is realized separating of gas and liquid, the refrigerant gas that does not separate fully in the process of distributing is again by filter assemblies 6 secondary separations, make that the whole of final arrival chamber 8 right side parts are refrigerant liquid, thereby make refrigerant liquid be assigned to uniformly in each heat exchanger tube.
The increasing refrigerant gas of separating is pumped into the compressor suction side of kind of refrigeration cycle continuously by the blast pipe 1 that is arranged on body top, makes that the gas flow of chamber 8 left part is stable, thereby guarantees that the right side part all is a refrigerant liquid.
Should be noted that because the volumetric ratio of whole chamber 8 is bigger, can store abundant refrigerant liquid, thereby play the effect of cold-producing medium fluid reservoir, so in whole cooling cycle system, the cold-producing medium fluid reservoir need not be set separately again.Not only can solve cold-producing medium uniform distribution problem according to bobbin carriage device of the present utility model, can also play the effect of fluid reservoir, therefore improved heat exchanger performance, guarantee stable overheated, simplified structure, raising unit reliability and reduce cost.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
